a suggestion along similar lines to personal heat is to use vivarium heat pads and place your bare feet on to them which will warm up your feet and your blood which then circulates and warms up your entire body and these can be USB powered and plugged into battery banks
@@joshuadelisle I got to the end and this video is as high quality as the ones I saw that made me want to sub and you're a brother in Christ to boot and I like the direction of your thinking with wanting to experiment with water heating... you could probably make use of computer water cooling pipes although I'd check first whether they're rated for heated water to the temperatures you're likely to encounter, typically as you probably know they carry the heat away from the components in a PC and those can get rather toasty. I look forward to seeing the next video
been using them for two years now, great when on the motorbikes (or using my mobility buggy) Looks you found some nice ones. I recharge my battery packs on my solar when I can, but only a small set up, so do have to use mains a lot too. Problems I found out were the buttons stop working after a small while, a lot of them just pull off from the wires which is a pain, but with the prices as they are, they are easily replaced.
And as true as all you've said is, isn't it extremely sad that as British people we're now planning on wearing heated clothes and using a dehumidifier just so we can afford to not be cold in our own homes and not then have mould and damp....while the energy suppliers make record profits and we're being charged more per unit than anyone else in the world.... What's happened to our once great country?
Ffs. What ever happened to personal responsibility. These little heat pads are great, but oh no, there's always some whinging halfwit... it has to be big energy or the govt or policemen are too young or working 25 hours a day when I was a lad
Well we know what happened to our planet... human beings overconsumed resources and energy, generating massive amounts of greenhouse gases, which could potentially wipe out billions of human beings, animal and plant life... if not worse. Cheap energy and resources and high wealth economies are the worst things that could have ever happened to our planet. The British have been some of the highest emitters / polluters on the planet since the late 1800s. North Americans are even worse. IMO, people looking for ways to save energy, while not giving our money away to greedy energy companies, isn't sad, it's something to be proud of and hopeful about. Saving money is just icing on the top. What is sad is how many people simply don't care enough to do anything to lower their footprint. In the past two years, I've had multiple friends decide to become frequent flyers. Not because they need to fly for work. In two egregious examples... two of my friends each have a favorite band. One started to fly around the US multiple times in a single year to visit her favorite band, dragging her husband along with her. The second friend some how got it in her mind that this was a great idea, so she started to do the same for her favorite band as well. Likely thousands of pounds of CO2 just to cavalarly fly around to see bands they've already seen multiple times this year, and who even visited our region in the past year. But it's not their fault... it's the energy company's fault. It's the airline's fault. It's everyone's fault but the wealthy individual humans who are consuming and polluting far more than the world can handle. And their footprint isn't a mystery. Environmental conditions and impact are all over the internet for everyone to see. I myself share all the things I do to conserve energy with my friends, and rather than take such ideas to heart, they're usually laughed at, scoffed at, or called crazy. One such simple thing... I stopped flying for vacation. Another thing, I ride my bike instead of driving every chance I get. I conserve water .I turn the HVAC down and wear warmer clothes. These actions are considered crazy. I do love all the westerners who have far more than the majority of the people in the world complaining when energy prices go up. If they have to spend so much on energy, then however will they afford their annual trip to another continent for vacation! This isn't a corporate problem... it's a greedy human problem.
Your just plane & simply brilliant 🤩 Perhaps you and your rooster should shoot over to the Brecon Beacons & try it out. I’m in West Sussex & it’s much too mild down here, even the postmen walk around year long in shorts! I have followed you for a while now, I do so enjoy your content & products you have put to the test. Thank you. Robert 🇬🇧
As a motorbike courier I have the cheap vest, heated insoles, heated gloves and mini heated pads I can put anywhere (all from Temu). I find the neck heating on the vest amazing, I don’t notice the body heating but it has a reflective layer on the inside and that I do notice for containing body heat. The heated insoles don’t keep the toes warm enough so I’ve resorted to the toe warmer version of the hand warmers that are chemically activated by air and they’re just amazing, even the cheapo ones I bought; you just have to give them 5 minutes out of the boots to activate properly. The cheap heated gloves are great under 40mph with handlebars muffs around 0 degrees but over that speed or lower than 0 I put the pads in the gloves too. I use a 27600mah power bank with modified cables and connectors going to everything and on full the gloves and vest alone blast through all those mah in around 8 hours. I’ve taken to relying on just the neck and glove heating most of the time with toe warmers, ah the toe warmers!
I just installed heated handlebars on my enduro bike. What a difference it makes! In ambient temps of about 4-6 C even when wet and covered in mud those two heaters which total about 120W on max are enough to keep me warm enough to be comfortable going about 60-80 km/h! The gloves i use have a really thin inside and well insulated and windproof outside.
@@joshuadelisle the navy did some great studies on heating systems for core, head and gloves. If you core and head are warm enough, the body does not restrict blood circulation to the arms and legs to slow heatloss. A warmer core keeps your fingers warm. I use the silicone encapsulated heating pads for diving. The 100m rated battery tank outside the dry suit provides 6,9 or 12V and keeps me warm in winter, especially during decompression the end of the dive (better blood flow in tissue improves getting rid of nitrogen)
Here in sunny Sheffield, me and our lass put an electric blanket down on the settee then cover our legs with a single duvet. Blanket draws 45w and is toasty warm. Got a dehumidifier to deal with the condensation and will get another for the upstairs. Done this for the last few years. Dehumidifier also dries the washing but it does take time. How are your bees. I have 8 hives myself.
I work in below freezing conditions all winter.....if you can keep your hands, feet and head warm the rest of you stays warm.....electric socks need the elements to go around the toes to be effective i found
My Knees are the only bits that seem to suffer badly from the cold!! My feet sometimes, but mostly my knees!! Thank you J for making and sharing this!!
I love your videos mate. I seem to remember the Americans (it might have been the US military or maybe NASA) did some tests where they put test subjects in cold water baths to see how long they could tolerate low temperatures. They then provided the subjects with heated copper tubes they could hold in their hands. That was the only heating source but they found that subjects could tolerate low temperatures much longer. It was based on the assumption that your hands (and hot the top of your head) are the biggest heat absorbers or radiators in the body. It worked the other way too - cold pipes for subjects in hot water baths.
I like the idea at the end for a liquid heat exchanger. That would let you use a reversible heat pump, which would be even more efficient. Also greatly appreciate your testing there. Most channels would have left it at a bought item or just theoretical. But seeing it in use is great. Cheers!
Your videos are brilliant My wife thinks im nuts after trying your experiments Keeps the old gray matter flowing Thanks for putting your interesting info out there
I understand it's not popular, but I like the idea of somebody doing a good job being rewarded for it and I am a subscriber because of the good work that you do. Makes me feel good there's still people to carry on it can be competent and do a great job presenting a product or some item. Thank you for a great video
Thank you for your support. I hope to bring to light products and ideas that are most valuable to you and cost effective. I get a kick back no extra cost to anyone if they use my links. cheers J
I bought 3 pairs of the heated inner soles to insert in clothes, £12.50 shipped. Not heating the house and not seeing any damp, probably because any moisture remains evenly distributed rather than condensing on cold spots. Generally resistive heating is an expensive option but when it's this well targeted it's cheap as chips.
I have had my Ororo for two years, it's awesomeness, lasts about five hours. The newer version has a smaller and lighter battery but old version uses 18650 cells and is probably easier to rebuild if you like projects.
Gather round children, its story time. I remember when a friend of mine, from down South, was going out into the forests during the winter to do a bunch of measurements. He didn't have much experience being outside in the winter. He had bought a bunch of electrical heating clothing. I told him that they were going to make him cold, but he wouldn't listen. When he came back he was a lot more humble, he had been so damn cold. Basically what happened was exactly what i told him would happen. He went out, started the heaters. Got a bit to warm and got sweaty. Then the batteries ran out and then he got REALLY cold. The next time he went out I lent him a bunch of woolen clothes and a thermos of hot coco. It was actually colder that week but he was fine. . In short, the trick to staying warm in the winter is 3-4 layers of clothes (adapting the layers so that you feel slightly cool and don't get sweaty), changing socks often, eating and drinking a lot. Wool is king.
@@joshuadelisle My friend said basically the same thing, he still got to warm and then had to suffer the consequences. = ) I grew up in, and spend a fair bit of time outdoors, in a sub-arctic climate. Your use-case is kind of different, since its basically going from keeping the house warm to mostly just keeping you warm, so its not the same as being out and away from power sources for entire days. I mean, you could run electric socks, long johns and a vest on full blast 24/7 for way less than it would cost to heat a house to ~20C in the winter.
yep, you can change the volt or amps to change how hot the pads get, for safety you could silicone onto the pads some Normally Close Temperature Controller Switch KSD9700 that are rated to stop the power when the pads get to a certain temp. they also make 12v XH-W3001 current limiters based on a temp probe.
Carpenter here working in unheated workshop all day. Been using these for years, the cheaper under garment ones are best as you can wear usual top layers over it. For feet the heated insoles are better than socks and can be purchased with battery packs (From amazon) that last about 10hrs on medium which just about lasts a working day for me. Have been using the current set for 5 years and still working perfectly.
BTW! CHEERS MATE! I Really love that you chose to do this! Since I started riding a motorcycle, And after having done my mandatory conscription military service, having experienced sleeping outside In SWEDISH FREEZING COLD winter! I first heard of and considered battery heated socks etc some 40 years ago! HOWEVER I never: "Got my thumb out"… TO actually GET some of the battery heated socks or layers! BUT now it is back in my consciousness! AS I am 59 years now - I LOATHE being cold and freezing in the DAMP Southern Swedish Winter! What I have done instead is: I have found and become totally impressed with and kind of: "crazy about": MERINO WOOL !, Angora/Cashmere WOOL! AND multiple breathable layers! BUT at many occasions a set of battery heated: underwear and socks - would be glorious!
Thank you. Yes Merino wool is excellent 👌. Cold feet are my Achilles heel... And cold hands. They're also where most of the blood flows so you get a lot of heat gain and loss though those parts. Cheers J
I recently bought a pair of (stick: 3" x 1" x 1" ) electric hand warmers. I have a couple of (airsoft? `grenade`) pouches with belt loops. They fit on my belt at the rear, over a polo shirt but under a fleece gillet and a thick fleece. Warm air drifts up my back during the day. A further set of handwarmers would fit into the front pockets of the gillet. My hand warmers last over 12 hours on the low setting. On chilly nights, hand warmers go inside: a) a loosely knotted sock or b) small neoprene pouch or c) tiny tent-peg bag that sits fairly securely under the quilt at the edge of the bed. They operate like a low power hot water bottle that can be switched on or off when required.
That's awesome. I have a Zippo hand warmer that runs on lighter fluid. It sounds dangerous but it's actually really good and very cheap to refill. Cheers J
I haven't seen the silicone pads before they look quite handy, you can also get usb heated sleeping bags and 12v blankets quite cheap. Regarding trying other methods pumping hot water is an interesting idea, also using something like a sand battery maybe. In Germany they have sleeping pods for the homeless called ulmer nests, they are insulated pods with solar panels and led lights inside. At the cheaper end there is another one called the Iglou its an emergency shelter made from foam. Combining a cheap shelter with solar usb heating or similar would probably save many homeless people in winter. It would also make winter camping enjoyable, better than freezing your nuts off lol. Good video, interested to see what it evolves into 👍
Something in between: turn the heat down at night, and an electric mattress pad. Keeps the whole bed nice and toasty. Uses a few more watts, but you're not wired into anything.
I actually tested a heated blanket with a solar power bank in another video coming up soon. I've had IT problems so it's been delayed for now. Cheers J
I just sleep in a cold room/bed. The bed will warm up after a minute from body heat, if you have the right blanket. I feel like I fall asleep faster, too.
During the shutdown I was eating in my car at work because I didn't trust the lunch room, being in Canada and winter (-20C is fairly common) and not having great heat in the car I bought a heated hoodie. (The battery that came with it only lasts about 3 hours but if you only use it during break time you get about a week out of it.) Best thing ever! I bought a second one for when not at work (I don't want to smell like factory at home or out and about). I prefer the ones that use the 5V USB over the 7.5V 4mm plug just because spare battery packs are easier/cheaper to get, yes they don't get as hot, but a spare battery (and more energy storage) is well worth the trade off (especially if you have an outer layer on).
@@joshuadelisle One thing I forgot to mention I also bought a Battery powered handwarmer at the same time (basically a standard power pack with a heater built into the case in a pleasant shape) and that is even better than having heated pockets (because you can stick it in any pocket of any jacket or holding it like a hot cup of tea). I've even seen someone use one to keep drone batteries warm on a snowmobile trip (several hours on a -10C day out in the wilderness, the cold would have drained the batteries for the drone before they would have been used).
Problem with the silicone tubes might be kinks which will stop the flow. There's reinforced ones, but for lots of movement it could still get tricky. Would love to see the experiment tho!
I used to use one of the cheap ones as a second layer when I had my workshop. T-shirt, the heated body warmer, a jumper and good to go. When really cold I used to add a thick body warmer
Excellent, well thought out experiment, good job! However, don't underestimate the efficiency of thermal underwear like Damart. Wearing a full set under layered clothing and, if necessary, a hot water bottle strategically placed in my stomach, I can stay warm all night for zero cost apart from the initial outlay. If physically active, there is no need for a hot water bottle as you will be generating enough heat to keep you warm without supplementing it.
Maybe target heating where the blood is close to the surface of the body? Then your blood moves the heat around the body? I'm thinking arm pits, inner thigh, neck, and wrists? In theory your body will cut blood flow to your fingers and toes if it's loosing too much heat, so if your fingers and toes are cold then heating your body elsewhere can make them more comfortable. At least up to the limit where your foot is submerged in a fast flowing ice cold river or similar, I guess, and your body can't deliver enough heat to it to keep it warm?
Definitely. Apparently there was a study and heating hands had the best effect. I would imagine the neck would be good. However a lower back and shoulders would be just lovely. Cheers J
I'm a gadget guy but the last time I checked a blanket or a sweater works in all weather, day or night, never needs to be charged and if it gets wet it isn't destroyed (or at least requiring repair). The best part is that people throw these things out all the time so you can literally get them VERY cheaply, or even for free in some cases. If my grandmother had lived long enough to see me wearing a battery powered vest to keep warm she would smack my upside the head until I didn't notice I was cold. I still love your reviews and process though so PLEASE do not take this as a criticism of you or your videos. I'm just truly let down by humanity and how delicate we have become. lol
You're totally right. A lot of people complain about their heating bills but don't think to put on a jumper... The best thing is if you do feel the cold between getting changed or being in sub zero temperatures then a few minutes with a heated vest makes a massive difference. The key point is what to do with the house if the heating is turned off so you don't get frozen pipes or mould from high humidity. Cheers J
bad circulation in humans is a thing... inability to be mobile through various conditions is a thing...... peoples metabolisms differing is a thing........extreme weather changes in quick succession denying people the ability to adapt well is a thing..... these toasty jackets cost little to purchase and run.... so the next time you take a bath.. maybe take your own advise and not run hot water... simply jump in and flap about for an hour.. u know.. so granny doesnt clip you up the side of the head for being a snowflake .... peace
I like the idea of the water heated clothing with the tube. I guess you could reverse it and use it for cooling in summer too. Interested to see what you come up with. A small log burner on your back? Maybe something that uses tealights? Or a gas burner powered by methane from your farts? the possibilties are endless.
Lol. Yes that's the idea. You can get lighter fluid powered hand warmers from Zippo. They work really well actually. I could easily rig it to be powered with one. Cheers J
I would definitely be interested in seeing a solution with flowing coolant through it. Something that interests me is something like a powered exoskeleton or power armor and I've always thought if I did that it would need a liquid heating and cooling solution like that. So it would be neat to see it work in any context.
It's called pacamama. They're hand knitted and lined with fleece. Very good quality. I was given mine by my mother in-law who bought it second hand. I bought the hat to match. Cheers J
I found a down blanket on Amazon for about $60, it works wonderfully and without any use of power! I get in my chair and use this blanket and keep plenty warm during the winter without using gas or more heat
Could you form your own water heating/cooling panels out of plastic bags that you strategically melt together in strips into a kind of labyrinth? And face it with Mylar heat reflective coating to reflect your body heat back? Make the whole torso one big water heat transfer panel!
Great video, and appreciate how you explain things. Point about the future pumped fluid idea...I wouldn't. Electric heating is 100% efficient but as soon as you introduce fluids, pumps etc you will have consequential losses. I love your ideas about undervolting the silicone heaters. Great stuff!
Yes however the inefficiency of a mechanical design you're referring to is mainly energy lost as heat which in this application is helpful. Electricity from the grid however isn't efficient at all, the steam turbines are only 40% efficient, solar is 20% efficient and 20% on top is lost through the grid as heat from transformers and wires. The idea is to reclaim heat from free resources using a water cooling system which is very effective. Cheers J
26:20 You will NEVER get anywhere near 200 watts from a 200 watt solar panel at dawn, even in June. You won't get more than 25 or 50 at sunrise in the Winter, a week and half before Christmas. This is especially true if you have them facing south on an angle equal to your latitude, which is where solar panels should be.
IF THE UK GOVERMENT GAVE OUT THAT STUFF TO UK PENSIONERS INSTEAD OF CUTTING THEM OFF FROM THE ENERGY PAYMENT THEY WOULD SAVE MONEY THEY WAST ANYWAY ON GOVERMENT INEFICENCYS AND CRONYISUM AND OUT PENTONERS WOULD NOT FREEZE TO DEATH
I build home battery backup systems, and I've been telling my clients this for years - you will use less energy keeping your family warm with DC heated blankets and outerwear for a MONTH than you otherwise would with a resistive space heater in a DAY. And if you're worried about frozen pipes bursting - buy a few extra heated blankets, and place them strategically around the most exposed pipes. It really doesn't take much preparation to save your family and home from the worst impacts of many common emergency scenarios.
Got some plug in thermostats with accurate temperature measurement and adjustable hysteresis. I think it's important you decide on the lowest temperature you feel you want. e.g. nook/snug/nest concept and not heating the whole room; seating safe from draughts, and sufaces you see about 23C. Need to understand conductive, convective, radiative, and air you breathe losses. CO2 build up, oxygen, gases, moisture and ventilation requirements means it's not so easy for people or animals. Turn on the boiler?
Been thinking of getting one for some time now, thanks for doing a test. Some flexwing( microlite) pilots use these when flying. Not sure which version. However they are handy as they draw very little power considering the output from the aircraft is small, so power usage has to be kept to a minimum. If interested a chap called Paul Hamilton did a video about this.
Hey Joshua, another great video! Your last idea sounded really interesting ever considered doing that on your mattress? There is this company that sells it for upwards of 4000€. I would love to see a DIY build for that.
I have had Cold store sollopettes for over 5 years now from work as temperature can drop well below zero overnight they are called flexitog x28 and they are the nuts, a worknbuddy bought the jacket that they make as well and he literally wears shorts and a t-shirt underneath in the coldest of months, sitting still for long periods you do feel the cold a bit but as soon as you start moving around you warm up in minutes, just body heat and the quality is excellent the sollopettes are less than £80 now when we got them they cost over £120 I've used mine every winter for at least 5 years maybe 6 or 7 this year and they are still like new, with your warmer kit trust me you would be toasty all the time if camping, they are like a sleeping bag best thing I've found and tried loads of thermal underwear, multiple layers ect and I ride a motorcycle well not all year round now but did years ago and wish I had the cold store trousers back then they are designed for cold store workers so zero and below temps, I'd love to see the jacket and sollopettes with the heaters together, the socks are a good idea that's about the only thing that gets cold mainly down to wearing steel toe cap, I'm the same though wear shorts almost all year round legs never seem to get cold but once you wear the sollopettes you will see they warm everywhere so we must lose alot of heat in the legs as well they cover from chest down I just where a normal high vis jacket and I get too hot if I'm doing anything manual for more than 10 minutes with them on just pop my jacket off and unzip the sollopettes at the front and you cool down!
one big downside of these jackets is the fact you can get burns quite easily. I’d highly recommend using the one with coils with more surface area. Also, be careful with overheating powerbanks and try avoiding sleeping in these jackets, because heat is heat, electricity is electricity, things can go bad and you can go up in flames.
you do know the jacket goes on the outside right ? used these for 20 years + and its the lack of heat that becomes a problem if you dress correct if you use brand names like bosch or milwaukee ofcourse only thing i would not sleep in is underwear and socks, its not like these self combust all the time
I use a desiccant dehumidifier as a heater. It gets my room up to 16C and humidity right down, all for 350W. I also wear fake sheepskin trousers and top, and a heated jacket when it gets exceptionally cold. My bills are mostly standing charges.
A few heat pads in a bed of sand and bedding on top with a heated blanket, a huge solar system even the sofa could be on when watching tv, the vest would be nice for portable around anywhere. A portable diesel heater can be used for a half hour or so when liked if you have a steady amount of money for fuel so on. I bet people could get away with some back up generator systems two or so for good measure and some smart batteries with a solar system the bigger the better for bad weather, because a big systems will still produce power on cloudy or winter days when cleaned.
I have an iheat one of these and it's really good. Three different settings and the battery lasts a good 8 hours. It was 99 quid on offer, so a decent one but when i get chilly just sitting around at home or at work, it's well worth it.
This sounds really interesting as I have Ankylosing Spondylitis (neck mainly)(I think?) Arthritis etc. I can’t move my neck at the moment and have a fan heater on it whenever I can. Luckily, we have solar and a battery. I am going to adapt a car battery also and bolt it outside. I am on morphine for pain in back , shoulders and neck. Add needing new knees. Im 56 btw. Love your channel and you are obviously very clever. You are similar thinking as myself. I have a large workshop at home as I will never live to claim my small pension anyway due to Crohn’s and Primary sclerosing cholangitis (PSC) all are related. Keep up the good work.
I pray for your recovery if that's possible. The ororo was fantastic on the neck but just too pricey. I think a DIY version that can be placed exactly where it's needed maybe best. Cheers J
Hi Josh, thanks for covering this topic. 99% reductions in heating cost can only be described as hacks. Did you already handle the topic of efficient moisture removal elsewhere?
Not yet but I'm considering doing something around the subject. Especially heat recovery ventilation and comparing dehumidifiers and alternative methods. Cheers J
I'd suggest trying the "Air Warrior microclimate vest" for your heated/cooled water pump idea, it's military surplus, relatively cheap and tested already, been thinking about giving it a try myself as I work outdoors.
I feel like it might be possible to stitch a fine enamel-coated wire on a zigzag stitch up and down into a standard vest or t-shirt, or trousers etc and then apply an amount of voltage appropriate to the final resistance value. Use of the zigzag stitch to prevent the wire reducing the stretchiness of the original fabric too much.
That's basically how the heating elements are made with just sandwiched in silicone or felt. I think a temp sensor and relay would be a good addition. Cheers J
Great experiment. Surely if the heating pads are inside pockets in a dowb gillet that would be best,because if you heat your lower core then the heat rises and is trapped by the down. The neck element seems a waste and would be better on the lower back area. Have you ever seen one of those sleeping bags that have arms and legs, well if you could make a thin suit with many of the heat pads attached then sleep in the sleeping bag suit that could be a great way to winter camp
How Apt! I have an Ororo & looking for a cheap alternative. All the cheap ones seem crap and fall apart from reviews Ive read. Also need to look at voltage. Ororo use 7.4v batteries, 2*21700 in parallel or series or whatever doubles the voltage. Using a cheap powerbank won't deliver the same heat
What a great review! What is the make of the woolly jacket and hat? I have been following your videos for some time, and you certainly excel at providing information. Thank you.
We have a fixed allowance deal so we get 11,000Kwh a year for a fixed monthly fee of £130 - The whole house is electric now the only thing we had was GCH but that was replaced by a 250L Water tank.I do run glass panel heaters and also IR heaters which do the same job as this in regards to heating the person not the space
Hi josh I brought a load of portwest af84 insulated fire retardant coveralls at auction about £10 each. They are super toasty . Then I brought a 100 tins of Adidas shoe protection spray 60p a tin. Next I'm going to use a tin or two to waterproof the coverall so I can stand out in torrential rain and remain dry . I tried a tin on a old combat jacket and the water now just bounces off . I have a set of merino wool bottoms and a £13 heated vest off Ali express.. For batteries I brought 50 x 4ah power banks £75 . Will never run out of heat or emergency power for phone. Love auctions..
Imagine a heated jacket but it had a layer of super quilt insulation usually used in the building industry as the "down" oh that would be a cosy jacket!
The main reason the elderly like it warmer is that they have lower metabolism and just output less heat energy. They often also have less fat too (as natural insulation). So they genuinely need a slightly warmer environment to feel conformable. I enjoy watching the way you follow your curiosity and test theories (reporting both success and failure).
Great video on the heated clothing & laser cutting. I'm waiting anxiously for your reviews on the toolbox diesel heaters. I've just completed my polycarbonate greenhouse. I'm going to install a diesel heater. From your underfloor heating experiment, I'm about to start fabricating a stainless steel clarifier to heat water from the exhaust & experiment piping the warm water through my growing beds, or a starter bed to raise seedlings?? 😊
These work great, I also use heated wraps and blankets with timers. Had an RV, and if I woke up at 3am and was cold, I just hit the switch and went back to toasty sleep in a few minutes. Having a timer is a good idea if it is an option. It saved a ton on propane costs instead of running the furnace all night.
Could you use the silicone pads and mod a sleeping bag? Only need one connection to the power supply and you would be free to roll about without tying yourself in knots.
Definitely. I think you can even buy electric sleeping bags now. A simple electric blanket as an underlay would work too. A timer and/or a temp sensor would be ideal. Cheers J
Much as i'd like the hijinks of the silicon tubing for warming you up. I feel like that will be a project in frustration for you. The tubing is likely to kink or your weight will close it off unless it's very rigid or large diameter and if it's large diameter it's not going to have good heat transfer. But if you want to stab at it, by all means.
4.6C is spot on my favorite sleeping temperature. I actually have down to 1C in my bedroom that is completely unheated and only receive some air from the heated hall. When it's -25C outside it gets close to negative in the bedroom. I sleep so well in the cold and in the summer I can barely sleep at all. So if people think you are crazy... 😂 When it's below 10C I use a thicker blanket, below 5C and I can have a t-shirt on (otherwise naked). Yes I am very warn...
@@joshuadelisle how is it better not to sleep we all know this is just a excuse to dress up like a kid in the wintertime we all know that dude with the shorts on in the wintertime (that never works or breaks a sweat)
I got a cheap body warmer last year for my wife and she loved it. The only down size was the charge only lasting a few hrs but I'm thinking I might wear it at home as I work from home and have it plugged in with a USB and save me heating the whole house just to keep me warm! Edit, I've just got it out and started wearing it and I just have the back and collar on heat. I forgot how nice this thing is to wear 😁👍
As heated handlebar grips / heated seats exist, it should be possible to create heated foot-pegs. Also, as a lot of (southern) Europeans complain about engine heat, it must be possible to jig around with air flow, to warm up the feet and legs of the more northerly riders using engine heat.
@rogerandroid2186 I have heated grips and seats, and the bike also vents hot air on both sides after passing through the radiator. Keeps the legs warm. Feet do get cold, LOL.
I'd love to see the idea with the sewing tubes into clothes. I think Adam Savage did that for cosplay to keep him cool? I think he used a suit like astronauts use?
Dear Josh. Good content, thanks. I’ve just seen your ‘shorts’ (!😂) on the same subject. So felt obliged to make the same observation here. Beware of the cheap night rates, they’re only for 6/7 hours. You’ll need to bear that in mind as the daytime rate of these tariffs is (or was when I tried it) a LOT higher than standard. You probably can make it work if you’re very organised, have the necessary amount of batteries (1 didn’t cut it for me) and helps if you’re out all day. (Most pensioners aren’t).
Idea for a video - what exactly does an average household use in electricity? By that I mean actual appliances. You’d get some ‘participation’ on that one! A ‘questionnaire’ maybe? I don’t imagine that figures are readily available.eg are there more gas than electric ovens? Do employed people use microwaves more?? Which is more cost effective microwave or gas???
I have a midrange amazon vest branded as Loowoko (whatever that Ai generated nonsense means), it's like a budget version of the premium one you have, probably polyester filled etc. At £60 including a 10,000mah battery I have to say it's brilliant. In the depths of winter I wear it in the home office plugged into a decent usb wall charger and on battery tinkering in the shed. I would recommend not having them on too high for too long or really sleeping in them though, they can easily cause burns that you wouldn't imediately be aware of (well worth reading into). I have experienced something along these lines where it made my back feel very achey, worth bearing in mind I'm fit and healthy and in my early 30s.
That's a very good point. I'm learning that instead of full body heating, heating just your hands is enough. I think a temp sensor would work well. Cheers J
@@joshuadelisle heating the hands is a good move. I ride motorbikes all year round and suffer from Raynaud's not just from the cold but also vibration, heated grips are a godsend, heated gloves would be even better but they are expensive (as is anything when you stick the words motorcycle in front of it).
I loved your videos of smithing, metal working and design. Do you jave plans to do more of those videos in the near future? Being in sub tropical Qld Australia, I have zero interest in heating, and even less interest in thinking about it when we have humid 30+ days at thos time of year. :)
As a matter of fact yes. I have been commissioned to forge dog head barrier stands for the tower of London. I've got an arc droid to cut the bases out with too. Cheers J
Should you also factor in the life of such a heat pad or battery. Rechargeable batteries fail after a too-short a time, so could be expensive over time.
i have a heated vest that my kids are jealous of but after i received it i started thinking about the potential EMF exposure that cannt be good. i wonder if you can test different products for the degree of electrical effects beyond heat
You mentioned water cooling/heating through tubes in vests? That already exists - AS personal cooling systems for racing drivers! AND transforming a cooling system into a warming system, SHOULD BE a fairly attainable DIY project!
I've been playing with these for a while, cheaper ones at least and they keep failing. The heated collar is annoying and I cut the wires to the last one. The flashing button on the front is annoying, id rather not stand out. They really need to be close to work - I found putting the "puffer jacket" under another layer works better but then makes the insulation in it useless. Will have to consider a waistcoat style. Nice they have an option to turn off the front as its only my back that gets cold easily. I would look into battery packs with replaceable cells though, since its a shame to keep throwing out poor performing battery banks when cells can be replaced (and the older ones used for situations to suit).
Glad I didn't buy the sock ones then. Got the leggings which I haven't tested as the leggings set cold on a motorcycle doing 70MPH on the motorway at -4C which is the coldest I did a run from Oxford to the NEC "motorcycle live" show at Birmingham. but will at some stage, just annoyed I can't get my leathers over the top of them. Oh, and thanks for adding the links, I really like the set you found, I have some of the really easily ripped ones, OK for riding, but useless for spannering
@@ruzziasht349 it depends where the pocket is, the problem is they put it in the back so you have to move the jacket to the side when you sit down- the small battery does not take up much room, but that doesent last for a work day and the bigger battery have a very bad shape for your back i often use another pocket then the one for the purpose, and let the cable go on the outside bosch have a better placement for the battery
Cool I haven't seen these before. I can imagine the option to heat just the back might be quite nice for people working outside with back pain or aches.

a suggestion along similar lines to personal heat is to use vivarium heat pads and place your bare feet on to them which will warm up your feet and your blood which then circulates and warms up your entire body and these can be USB powered and plugged into battery banks
I see now you did cover something similar, I should have waited I forgot how thorough you are
@@plaguezero thank you. Yes that worked out well for me at the end of the video. Cheers J
@@joshuadelisle I got to the end and this video is as high quality as the ones I saw that made me want to sub and you're a brother in Christ to boot and I like the direction of your thinking with wanting to experiment with water heating... you could probably make use of computer water cooling pipes although I'd check first whether they're rated for heated water to the temperatures you're likely to encounter, typically as you probably know they carry the heat away from the components in a PC and those can get rather toasty. I look forward to seeing the next video
been using them for two years now, great when on the motorbikes (or using my mobility buggy) Looks you found some nice ones. I recharge my battery packs on my solar when I can, but only a small set up, so do have to use mains a lot too. Problems I found out were the buttons stop working after a small while, a lot of them just pull off from the wires which is a pain, but with the prices as they are, they are easily replaced.
And as true as all you've said is, isn't it extremely sad that as British people we're now planning on wearing heated clothes and using a dehumidifier just so we can afford to not be cold in our own homes and not then have mould and damp....while the energy suppliers make record profits and we're being charged more per unit than anyone else in the world.... What's happened to our once great country?
Yes I thought I would hold back on a political rant for now. Maybe in my follow up video I'll share my 2 pence on the subject. Cheers J
Ffs. What ever happened to personal responsibility.
These little heat pads are great, but oh no, there's always some whinging halfwit... it has to be big energy or the govt or policemen are too young or working 25 hours a day when I was a lad
Same in sweden..
Well we know what happened to our planet... human beings overconsumed resources and energy, generating massive amounts of greenhouse gases, which could potentially wipe out billions of human beings, animal and plant life... if not worse. Cheap energy and resources and high wealth economies are the worst things that could have ever happened to our planet. The British have been some of the highest emitters / polluters on the planet since the late 1800s. North Americans are even worse. IMO, people looking for ways to save energy, while not giving our money away to greedy energy companies, isn't sad, it's something to be proud of and hopeful about. Saving money is just icing on the top.
What is sad is how many people simply don't care enough to do anything to lower their footprint. In the past two years, I've had multiple friends decide to become frequent flyers. Not because they need to fly for work. In two egregious examples... two of my friends each have a favorite band. One started to fly around the US multiple times in a single year to visit her favorite band, dragging her husband along with her. The second friend some how got it in her mind that this was a great idea, so she started to do the same for her favorite band as well. Likely thousands of pounds of CO2 just to cavalarly fly around to see bands they've already seen multiple times this year, and who even visited our region in the past year.
But it's not their fault... it's the energy company's fault. It's the airline's fault. It's everyone's fault but the wealthy individual humans who are consuming and polluting far more than the world can handle.
And their footprint isn't a mystery. Environmental conditions and impact are all over the internet for everyone to see. I myself share all the things I do to conserve energy with my friends, and rather than take such ideas to heart, they're usually laughed at, scoffed at, or called crazy. One such simple thing... I stopped flying for vacation. Another thing, I ride my bike instead of driving every chance I get. I conserve water .I turn the HVAC down and wear warmer clothes. These actions are considered crazy.
I do love all the westerners who have far more than the majority of the people in the world complaining when energy prices go up. If they have to spend so much on energy, then however will they afford their annual trip to another continent for vacation!
This isn't a corporate problem... it's a greedy human problem.
Your just plane & simply brilliant 🤩
Perhaps you and your rooster should shoot over to the Brecon Beacons & try it out. I’m in West Sussex & it’s much too mild down here, even the postmen walk around year long in shorts!
I have followed you for a while now, I do so enjoy your content & products you have put to the test. Thank you. Robert 🇬🇧
As a motorbike courier I have the cheap vest, heated insoles, heated gloves and mini heated pads I can put anywhere (all from Temu). I find the neck heating on the vest amazing, I don’t notice the body heating but it has a reflective layer on the inside and that I do notice for containing body heat. The heated insoles don’t keep the toes warm enough so I’ve resorted to the toe warmer version of the hand warmers that are chemically activated by air and they’re just amazing, even the cheapo ones I bought; you just have to give them 5 minutes out of the boots to activate properly. The cheap heated gloves are great under 40mph with handlebars muffs around 0 degrees but over that speed or lower than 0 I put the pads in the gloves too.
I use a 27600mah power bank with modified cables and connectors going to everything and on full the gloves and vest alone blast through all those mah in around 8 hours. I’ve taken to relying on just the neck and glove heating most of the time with toe warmers, ah the toe warmers!
Well done. That's awesome. Cheers J
I just installed heated handlebars on my enduro bike. What a difference it makes! In ambient temps of about 4-6 C even when wet and covered in mud those two heaters which total about 120W on max are enough to keep me warm enough to be comfortable going about 60-80 km/h! The gloves i use have a really thin inside and well insulated and windproof outside.
@@joshuadelisle the navy did some great studies on heating systems for core, head and gloves. If you core and head are warm enough, the body does not restrict blood circulation to the arms and legs to slow heatloss. A warmer core keeps your fingers warm.
I use the silicone encapsulated heating pads for diving. The 100m rated battery tank outside the dry suit provides 6,9 or 12V and keeps me warm in winter, especially during decompression the end of the dive (better blood flow in tissue improves getting rid of nitrogen)
750,000 UK pensioners need to see this guy's work.
I hope it helps someone. cheers J
You're covered on that.
Thank you.
"My sock stopped working" is not a phrase I thought I'd ever hear anyone say. 22:24
Lol. Cheers J
Mine too! My Eeectric insoles seem much more resilient
Here in sunny Sheffield, me and our lass put an electric blanket down on the settee then cover our legs with a single duvet. Blanket draws 45w and is toasty warm. Got a dehumidifier to deal with the condensation and will get another for the upstairs. Done this for the last few years. Dehumidifier also dries the washing but it does take time. How are your bees. I have 8 hives myself.
Nice. Well done. Cheers J
a good extractor fan is way cheaper than dehumidifier and it works for me
Extractor fans in the kitchen and bathroom should remove most of the moisture.
Yes, electric under blanket for the bed is really good also.
I work in below freezing conditions all winter.....if you can keep your hands, feet and head warm the rest of you stays warm.....electric socks need the elements to go around the toes to be effective i found
Those are the part most susceptible to frostbite, makes sense.
That's good information. Cheers J
Amazon are currently selling: Heated Insoles, Electric Feet Warmers. I don't know if these would be any good or priced right ...
My Knees are the only bits that seem to suffer badly from the cold!!
My feet sometimes, but mostly my knees!!
Thank you J for making and sharing this!!
Thank you for watching. Cheers J
I love your videos mate. I seem to remember the Americans (it might have been the US military or maybe NASA) did some tests where they put test subjects in cold water baths to see how long they could tolerate low temperatures. They then provided the subjects with heated copper tubes they could hold in their hands. That was the only heating source but they found that subjects could tolerate low temperatures much longer. It was based on the assumption that your hands (and hot the top of your head) are the biggest heat absorbers or radiators in the body. It worked the other way too - cold pipes for subjects in hot water baths.
That's very interesting. I'll look into that. Cheers J
Seconded. Heating the hands is really efficient. Toes and feet probably decent too
I like the idea at the end for a liquid heat exchanger. That would let you use a reversible heat pump, which would be even more efficient. Also greatly appreciate your testing there. Most channels would have left it at a bought item or just theoretical. But seeing it in use is great. Cheers!
Thank you. Lots to come. Cheers J
I'd highly recommend "Adam Savage's One Day Builds: Refrigerated Cooling Suit"
Your videos are brilliant
My wife thinks im nuts after trying your experiments
Keeps the old gray matter flowing
Thanks for putting your interesting info out there
Thank you so much. It's not crazy if it works lol. Cheers J
Time for a wife upgrade
Probably better if the gray matter does not flow. ;)
You haven’t met my wife. Got to be alert 24/7😂
I understand it's not popular, but I like the idea of somebody doing a good job being rewarded for it and I am a subscriber because of the good work that you do. Makes me feel good there's still people to carry on it can be competent and do a great job presenting a product or some item. Thank you for a great video
Thank you for your support. I hope to bring to light products and ideas that are most valuable to you and cost effective. I get a kick back no extra cost to anyone if they use my links. cheers J
I bought 3 pairs of the heated inner soles to insert in clothes, £12.50 shipped. Not heating the house and not seeing any damp, probably because any moisture remains evenly distributed rather than condensing on cold spots. Generally resistive heating is an expensive option but when it's this well targeted it's cheap as chips.
Exactly. Cheers J
hi, can you give me temu links to any thin heatee gloves from 5 v batteries attached to the gloves for short duration usage. thanks
I have had my Ororo for two years, it's awesomeness, lasts about five hours. The newer version has a smaller and lighter battery but old version uses 18650 cells and is probably easier to rebuild if you like projects.
Nice 👍. Cheers J
You need thermistor temperature feedback, and a pulse width control to regulate the temperature.
Definitely. Cheers J
Gather round children, its story time.
I remember when a friend of mine, from down South, was going out into the forests during the winter to do a bunch of measurements. He didn't have much experience being outside in the winter.
He had bought a bunch of electrical heating clothing. I told him that they were going to make him cold, but he wouldn't listen.
When he came back he was a lot more humble, he had been so damn cold.
Basically what happened was exactly what i told him would happen. He went out, started the heaters. Got a bit to warm and got sweaty. Then the batteries ran out and then he got REALLY cold.
The next time he went out I lent him a bunch of woolen clothes and a thermos of hot coco. It was actually colder that week but he was fine.
.
In short, the trick to staying warm in the winter is 3-4 layers of clothes (adapting the layers so that you feel slightly cool and don't get sweaty), changing socks often, eating and drinking a lot.
Wool is king.
Agreed but you can also just turn it on when cold and off when you're good. That way you don't sweat. Cheers J
@@joshuadelisle My friend said basically the same thing, he still got to warm and then had to suffer the consequences. = )
I grew up in, and spend a fair bit of time outdoors, in a sub-arctic climate.
Your use-case is kind of different, since its basically going from keeping the house warm to mostly just keeping you warm, so its not the same as being out and away from power sources for entire days.
I mean, you could run electric socks, long johns and a vest on full blast 24/7 for way less than it would cost to heat a house to ~20C in the winter.
yep, you can change the volt or amps to change how hot the pads get, for safety you could silicone onto the pads some Normally Close Temperature Controller Switch KSD9700 that are rated to stop the power when the pads get to a certain temp. they also make 12v XH-W3001 current limiters based on a temp probe.
Excellent tip. Cheers J
Carpenter here working in unheated workshop all day. Been using these for years, the cheaper under garment ones are best as you can wear usual top layers over it. For feet the heated insoles are better than socks and can be purchased with battery packs (From amazon) that last about 10hrs on medium which just about lasts a working day for me.
Have been using the current set for 5 years and still working perfectly.
@@IronMountainx well done. Cheers J
BTW! CHEERS MATE! I Really love that you chose to do this!
Since I started riding a motorcycle, And after having done my mandatory conscription military service, having experienced sleeping outside In SWEDISH FREEZING COLD winter! I first heard of and considered battery heated socks etc some 40 years ago!
HOWEVER I never: "Got my thumb out"…
TO actually GET some of the battery heated socks or layers!
BUT now it is back in my consciousness!
AS I am 59 years now - I LOATHE being cold and freezing in the DAMP Southern Swedish Winter!
What I have done instead is: I have found and become totally impressed with and kind of: "crazy about":
MERINO WOOL !, Angora/Cashmere WOOL!
AND multiple breathable layers!
BUT at many occasions a set of battery heated: underwear and socks - would be glorious!
Thank you. Yes Merino wool is excellent 👌. Cold feet are my Achilles heel... And cold hands. They're also where most of the blood flows so you get a lot of heat gain and loss though those parts. Cheers J
I recently bought a pair of (stick: 3" x 1" x 1" ) electric hand warmers. I have a couple of (airsoft? `grenade`) pouches with belt loops. They fit on my belt at the rear, over a polo shirt but under a fleece gillet and a thick fleece. Warm air drifts up my back during the day. A further set of handwarmers would fit into the front pockets of the gillet. My hand warmers last over 12 hours on the low setting. On chilly nights, hand warmers go inside: a) a loosely knotted sock or b) small neoprene pouch or c) tiny tent-peg bag that sits fairly securely under the quilt at the edge of the bed. They operate like a low power hot water bottle that can be switched on or off when required.
That's awesome. I have a Zippo hand warmer that runs on lighter fluid. It sounds dangerous but it's actually really good and very cheap to refill. Cheers J
I haven't seen the silicone pads before they look quite handy, you can also get usb heated sleeping bags and 12v blankets quite cheap. Regarding trying other methods pumping hot water is an interesting idea, also using something like a sand battery maybe. In Germany they have sleeping pods for the homeless called ulmer nests, they are insulated pods with solar panels and led lights inside. At the cheaper end there is another one called the Iglou its an emergency shelter made from foam. Combining a cheap shelter with solar usb heating or similar would probably save many homeless people in winter. It would also make winter camping enjoyable, better than freezing your nuts off lol. Good video, interested to see what it evolves into 👍
Wow that's good to hear. Localised heating is definitely the most cost effective for sure. Cheers J
Something in between: turn the heat down at night, and an electric mattress pad. Keeps the whole bed nice and toasty. Uses a few more watts, but you're not wired into anything.
I actually tested a heated blanket with a solar power bank in another video coming up soon. I've had IT problems so it's been delayed for now. Cheers J
I just sleep in a cold room/bed. The bed will warm up after a minute from body heat, if you have the right blanket.
I feel like I fall asleep faster, too.
During the shutdown I was eating in my car at work because I didn't trust the lunch room, being in Canada and winter (-20C is fairly common) and not having great heat in the car I bought a heated hoodie. (The battery that came with it only lasts about 3 hours but if you only use it during break time you get about a week out of it.) Best thing ever! I bought a second one for when not at work (I don't want to smell like factory at home or out and about). I prefer the ones that use the 5V USB over the 7.5V 4mm plug just because spare battery packs are easier/cheaper to get, yes they don't get as hot, but a spare battery (and more energy storage) is well worth the trade off (especially if you have an outer layer on).
Nice. Yes a large pocket battery 40000mah can make it last all day. Coupled with a solar panel then it's free to heat all night. Cheers J
@@joshuadelisle One thing I forgot to mention I also bought a Battery powered handwarmer at the same time (basically a standard power pack with a heater built into the case in a pleasant shape) and that is even better than having heated pockets (because you can stick it in any pocket of any jacket or holding it like a hot cup of tea). I've even seen someone use one to keep drone batteries warm on a snowmobile trip (several hours on a -10C day out in the wilderness, the cold would have drained the batteries for the drone before they would have been used).
@@sunshaker01 why don't you 'trust' the lunch room? 😃
Problem with the silicone tubes might be kinks which will stop the flow. There's reinforced ones, but for lots of movement it could still get tricky. Would love to see the experiment tho!
I used to use one of the cheap ones as a second layer when I had my workshop. T-shirt, the heated body warmer, a jumper and good to go. When really cold I used to add a thick body warmer
@@BurtKwouk77 nice. Cheers J
Excellent, well thought out experiment, good job! However, don't underestimate the efficiency of thermal underwear like Damart. Wearing a full set under layered clothing and, if necessary, a hot water bottle strategically placed in my stomach, I can stay warm all night for zero cost apart from the initial outlay. If physically active, there is no need for a hot water bottle as you will be generating enough heat to keep you warm without supplementing it.
Hot water bottles are underrated. We love them. Especially boiling water on a fire from wood I've collected for free. Cheers J
Maybe target heating where the blood is close to the surface of the body? Then your blood moves the heat around the body? I'm thinking arm pits, inner thigh, neck, and wrists? In theory your body will cut blood flow to your fingers and toes if it's loosing too much heat, so if your fingers and toes are cold then heating your body elsewhere can make them more comfortable. At least up to the limit where your foot is submerged in a fast flowing ice cold river or similar, I guess, and your body can't deliver enough heat to it to keep it warm?
Definitely. Apparently there was a study and heating hands had the best effect. I would imagine the neck would be good. However a lower back and shoulders would be just lovely. Cheers J
I'm a gadget guy but the last time I checked a blanket or a sweater works in all weather, day or night, never needs to be charged and if it gets wet it isn't destroyed (or at least requiring repair). The best part is that people throw these things out all the time so you can literally get them VERY cheaply, or even for free in some cases. If my grandmother had lived long enough to see me wearing a battery powered vest to keep warm she would smack my upside the head until I didn't notice I was cold.
I still love your reviews and process though so PLEASE do not take this as a criticism of you or your videos. I'm just truly let down by humanity and how delicate we have become. lol
You're totally right. A lot of people complain about their heating bills but don't think to put on a jumper... The best thing is if you do feel the cold between getting changed or being in sub zero temperatures then a few minutes with a heated vest makes a massive difference. The key point is what to do with the house if the heating is turned off so you don't get frozen pipes or mould from high humidity. Cheers J
bad circulation in humans is a thing... inability to be mobile through various conditions is a thing...... peoples metabolisms differing is a thing........extreme weather changes in quick succession denying people the ability to adapt well is a thing..... these toasty jackets cost little to purchase and run.... so the next time you take a bath.. maybe take your own advise and not run hot water... simply jump in and flap about for an hour.. u know.. so granny doesnt clip you up the side of the head for being a snowflake .... peace
I like the idea of the water heated clothing with the tube. I guess you could reverse it and use it for cooling in summer too. Interested to see what you come up with. A small log burner on your back? Maybe something that uses tealights? Or a gas burner powered by methane from your farts? the possibilties are endless.
Lol. Yes that's the idea. You can get lighter fluid powered hand warmers from Zippo. They work really well actually. I could easily rig it to be powered with one. Cheers J
I would definitely be interested in seeing a solution with flowing coolant through it. Something that interests me is something like a powered exoskeleton or power armor and I've always thought if I did that it would need a liquid heating and cooling solution like that. So it would be neat to see it work in any context.
That's the end goal. Cheers J
Love your videos Josh! Another fascinating blend of diy tech to solve problems and innovate!
Merry Christmas
Merry Christmas. Thank you so much. Cheers J
Where do i get myself one of them fancy jackets you have ontop of it ? That thing is so dapper.
It's called pacamama. They're hand knitted and lined with fleece. Very good quality. I was given mine by my mother in-law who bought it second hand. I bought the hat to match. Cheers J
I found a down blanket on Amazon for about $60, it works wonderfully and without any use of power!
I get in my chair and use this blanket and keep plenty warm during the winter without using gas or more heat
That's great. Cheers J
Could you form your own water heating/cooling panels out of plastic bags that you strategically melt together in strips into a kind of labyrinth? And face it with Mylar heat reflective coating to reflect your body heat back? Make the whole torso one big water heat transfer panel!
It's a possibility. Cheers J
Great video, and appreciate how you explain things. Point about the future pumped fluid idea...I wouldn't. Electric heating is 100% efficient but as soon as you introduce fluids, pumps etc you will have consequential losses. I love your ideas about undervolting the silicone heaters. Great stuff!
Yes however the inefficiency of a mechanical design you're referring to is mainly energy lost as heat which in this application is helpful. Electricity from the grid however isn't efficient at all, the steam turbines are only 40% efficient, solar is 20% efficient and 20% on top is lost through the grid as heat from transformers and wires. The idea is to reclaim heat from free resources using a water cooling system which is very effective. Cheers J
its good to store batteries at around 50% charge , so the compact battery that was discharged slightly is a good thing
That's right. Cheers J
26:20 You will NEVER get anywhere near 200 watts from a 200 watt solar panel at dawn, even in June. You won't get more than 25 or 50 at sunrise in the Winter, a week and half before Christmas. This is especially true if you have them facing south on an angle equal to your latitude, which is where solar panels should be.
That's a fair point. Still a small battery charges pretty fast compared to a big system. Cheers J
IF THE UK GOVERMENT GAVE OUT THAT STUFF TO UK PENSIONERS INSTEAD OF CUTTING THEM OFF FROM THE ENERGY PAYMENT THEY WOULD SAVE MONEY THEY WAST ANYWAY ON GOVERMENT INEFICENCYS AND CRONYISUM AND OUT PENTONERS WOULD NOT FREEZE TO DEATH
I couldn't agree more. cheers J
I build home battery backup systems, and I've been telling my clients this for years - you will use less energy keeping your family warm with DC heated blankets and outerwear for a MONTH than you otherwise would with a resistive space heater in a DAY. And if you're worried about frozen pipes bursting - buy a few extra heated blankets, and place them strategically around the most exposed pipes. It really doesn't take much preparation to save your family and home from the worst impacts of many common emergency scenarios.
That's right. All you need to do is turn the central heating on to 10°c on days below freezing. In the UK that's not very often. Cheers J
I would have loved to have witnessed the conversation with your wife when you told her you were going to sleep outside in a hammock in December. LOL
She's not even suprised anymore to be honest with everything I get up to, especially the stuff that isn't on camera. lol. cheers J
Got some plug in thermostats with accurate temperature measurement and adjustable hysteresis. I think it's important you decide on the lowest temperature you feel you want. e.g. nook/snug/nest concept and not heating the whole room; seating safe from draughts, and sufaces you see about 23C. Need to understand conductive, convective, radiative, and air you breathe losses. CO2 build up, oxygen, gases, moisture and ventilation requirements means it's not so easy for people or animals. Turn on the boiler?
Been thinking of getting one for some time now, thanks for doing a test. Some flexwing( microlite) pilots use these when flying. Not sure which version. However they are handy as they draw very little power considering the output from the aircraft is small, so power usage has to be kept to a minimum. If interested a chap called Paul Hamilton did a video about this.
Nice. Thank you. Cheers J
Hey Joshua, another great video! Your last idea sounded really interesting ever considered doing that on your mattress? There is this company that sells it for upwards of 4000€. I would love to see a DIY build for that.
thank you. i'll look into it. cheers J
I have had Cold store sollopettes for over 5 years now from work as temperature can drop well below zero overnight they are called flexitog x28 and they are the nuts, a worknbuddy bought the jacket that they make as well and he literally wears shorts and a t-shirt underneath in the coldest of months, sitting still for long periods you do feel the cold a bit but as soon as you start moving around you warm up in minutes, just body heat and the quality is excellent the sollopettes are less than £80 now when we got them they cost over £120 I've used mine every winter for at least 5 years maybe 6 or 7 this year and they are still like new, with your warmer kit trust me you would be toasty all the time if camping, they are like a sleeping bag best thing I've found and tried loads of thermal underwear, multiple layers ect and I ride a motorcycle well not all year round now but did years ago and wish I had the cold store trousers back then they are designed for cold store workers so zero and below temps, I'd love to see the jacket and sollopettes with the heaters together, the socks are a good idea that's about the only thing that gets cold mainly down to wearing steel toe cap, I'm the same though wear shorts almost all year round legs never seem to get cold but once you wear the sollopettes you will see they warm everywhere so we must lose alot of heat in the legs as well they cover from chest down I just where a normal high vis jacket and I get too hot if I'm doing anything manual for more than 10 minutes with them on just pop my jacket off and unzip the sollopettes at the front and you cool down!
@@danielduke5059 nice. Cheers J
I got a so called 13 zone heated jacket from Temu for £13 delivered to the UK. Yes it's cheaply built but it seems to do the job.
Nice. Cheers J
one big downside of these jackets is the fact you can get burns quite easily. I’d highly recommend using the one with coils with more surface area.
Also, be careful with overheating powerbanks and try avoiding sleeping in these jackets, because heat is heat, electricity is electricity, things can go bad and you can go up in flames.
That's very wise and definitely something to consider. Cheers J
you do know the jacket goes on the outside right ?
used these for 20 years +
and its the lack of heat that becomes a problem if you dress correct
if you use brand names like bosch or milwaukee ofcourse
only thing i would not sleep in is underwear and socks, its not like these self combust all the time
My ex girlfriends underwear used to self combust 🙄
I use a desiccant dehumidifier as a heater. It gets my room up to 16C and humidity right down, all for 350W. I also wear fake sheepskin trousers and top, and a heated jacket when it gets exceptionally cold. My bills are mostly standing charges.
Nice 👍. Cheers J
UTILITA- NO STANDING CHARGES - PAY MORE FOR FIRST 2 UNITS 👍
Same rig, but for sleeping use an automobile 12v electric blanket.
Nice. Cheers J
A few heat pads in a bed of sand and bedding on top with a heated blanket, a huge solar system even the sofa could be on when watching tv, the vest would be nice for portable around anywhere. A portable diesel heater can be used for a half hour or so when liked if you have a steady amount of money for fuel so on. I bet people could get away with some back up generator systems two or so for good measure and some smart batteries with a solar system the bigger the better for bad weather, because a big systems will still produce power on cloudy or winter days when cleaned.
Sounds like a plan. Cheers J
For camping use a 12v heater blanket, yep same as the one you have on your bed inside.
They work great until you get out of bed. Cheers J
I kinda wanna see a DIY version of this tbf it's cool to see these products but they're all pretty basic
I have an iheat one of these and it's really good. Three different settings and the battery lasts a good 8 hours. It was 99 quid on offer, so a decent one but when i get chilly just sitting around at home or at work, it's well worth it.
Nice. cheers J
This sounds really interesting as I have Ankylosing Spondylitis (neck mainly)(I think?)
Arthritis etc. I can’t move my neck at the moment and have a fan heater on it whenever I can. Luckily, we have solar and a battery. I am going to adapt a car battery also and bolt it outside.
I am on morphine for pain in back , shoulders and neck. Add needing new knees. Im 56 btw.
Love your channel and you are obviously very clever. You are similar thinking as myself. I have a large workshop at home as I will never live to claim my small pension anyway due to Crohn’s and Primary sclerosing cholangitis (PSC) all are related.
Keep up the good work.
I pray for your recovery if that's possible. The ororo was fantastic on the neck but just too pricey. I think a DIY version that can be placed exactly where it's needed maybe best. Cheers J
Hi Josh, thanks for covering this topic. 99% reductions in heating cost can only be described as hacks. Did you already handle the topic of efficient moisture removal elsewhere?
Not yet but I'm considering doing something around the subject. Especially heat recovery ventilation and comparing dehumidifiers and alternative methods. Cheers J
@@joshuadelislesounds great, sir.
I'd suggest trying the "Air Warrior microclimate vest" for your heated/cooled water pump idea, it's military surplus, relatively cheap and tested already, been thinking about giving it a try myself as I work outdoors.
I'll check it out. Cheers J
Thank you. I'll check it out. Cheers J
It's MORE than 1 week to Christmas NOW.
Near enough a week lol.
PLEASE PLEASE where did you get that jumper. So want it. It’s awesome
I've put a link in the description for you. Cheers J
I feel like it might be possible to stitch a fine enamel-coated wire on a zigzag stitch up and down into a standard vest or t-shirt, or trousers etc and then apply an amount of voltage appropriate to the final resistance value.
Use of the zigzag stitch to prevent the wire reducing the stretchiness of the original fabric too much.
That's basically how the heating elements are made with just sandwiched in silicone or felt. I think a temp sensor and relay would be a good addition. Cheers J
@joshuadelisle true, I feel by going full custom, one could to an entire garment rather than just a few zones though
Great experiment. Surely if the heating pads are inside pockets in a dowb gillet that would be best,because if you heat your lower core then the heat rises and is trapped by the down. The neck element seems a waste and would be better on the lower back area.
Have you ever seen one of those sleeping bags that have arms and legs, well if you could make a thin suit with many of the heat pads attached then sleep in the sleeping bag suit that could be a great way to winter camp
We'll all be walking around like characters out of the film Dune soon
Lol. Could be... Cheers J
How Apt! I have an Ororo & looking for a cheap alternative. All the cheap ones seem crap and fall apart from reviews Ive read. Also need to look at voltage. Ororo use 7.4v batteries, 2*21700 in parallel or series or whatever doubles the voltage. Using a cheap powerbank won't deliver the same heat
@@Chris_Willows thank you. You're right. The 5v can be boosted or use a 12v power bank and reduce the power with a buck converter. Cheers J
What a great review! What is the make of the woolly jacket and hat? I have been following your videos for some time, and you certainly excel at providing information. Thank you.
Thank you so much. I've put a link in the description to the brand for you. Cheers J
We have a fixed allowance deal so we get 11,000Kwh a year for a fixed monthly fee of £130 - The whole house is electric now the only thing we had was GCH but that was replaced by a 250L Water tank.I do run glass panel heaters and also IR heaters which do the same job as this in regards to heating the person not the space
@@petecoventry6858 that's not bad. Cheers J
Also if you want to control the temp you could get a DC Dimmer Switch and wire it in between the power and pads to dial in the temp you want.
Definitely. I wish I did that for the foot pads because they get too hot. Cheers J
Hi josh
I brought a load of portwest af84 insulated fire retardant coveralls at auction about £10 each.
They are super toasty .
Then I brought a 100 tins of Adidas shoe protection spray 60p a tin.
Next I'm going to use a tin or two to waterproof the coverall so I can stand out in torrential rain and remain dry . I tried a tin on a old combat jacket and the water now just bounces off .
I have a set of merino wool bottoms and a £13 heated vest off Ali express..
For batteries I brought 50 x 4ah power banks £75 .
Will never run out of heat or emergency power for phone.
Love auctions..
@@sftatat nice. me too. I got my entire workshop PIR Kingspan for £30 at auction. I'm looking for more for my outdoor office/studio. Cheers J
Imagine a heated jacket but it had a layer of super quilt insulation usually used in the building industry as the "down" oh that would be a cosy jacket!
The main reason the elderly like it warmer is that they have lower metabolism and just output less heat energy. They often also have less fat too (as natural insulation). So they genuinely need a slightly warmer environment to feel conformable.
I enjoy watching the way you follow your curiosity and test theories (reporting both success and failure).
Great video on the heated clothing & laser cutting. I'm waiting anxiously for your reviews on the toolbox diesel heaters. I've just completed my polycarbonate greenhouse. I'm going to install a diesel heater. From your underfloor heating experiment, I'm about to start fabricating a stainless steel clarifier to heat water from the exhaust & experiment piping the warm water through my growing beds, or a starter bed to raise seedlings?? 😊
@@stephenjlangford2451 I've had IT problems so it's on hold for now. I've not had great experience with the toolbox designs so far though. Cheers J
These work great, I also use heated wraps and blankets with timers. Had an RV, and if I woke up at 3am and was cold, I just hit the switch and went back to toasty sleep in a few minutes. Having a timer is a good idea if it is an option. It saved a ton on propane costs instead of running the furnace all night.
That's great. I'm thinking of introducing a temp sensor that kicks in before I feel the cold. Cheers J
Could you use the silicone pads and mod a sleeping bag? Only need one connection to the power supply and you would be free to roll about without tying yourself in knots.
Definitely. I think you can even buy electric sleeping bags now. A simple electric blanket as an underlay would work too. A timer and/or a temp sensor would be ideal. Cheers J
Much as i'd like the hijinks of the silicon tubing for warming you up. I feel like that will be a project in frustration for you. The tubing is likely to kink or your weight will close it off unless it's very rigid or large diameter and if it's large diameter it's not going to have good heat transfer. But if you want to stab at it, by all means.
It's worth a try and highlight those issues. Cheers J
4.6C is spot on my favorite sleeping temperature. I actually have down to 1C in my bedroom that is completely unheated and only receive some air from the heated hall. When it's -25C outside it gets close to negative in the bedroom. I sleep so well in the cold and in the summer I can barely sleep at all. So if people think you are crazy... 😂
When it's below 10C I use a thicker blanket, below 5C and I can have a t-shirt on (otherwise naked). Yes I am very warn...
Doesnt sound very healthy for your house.
It's actually better for you to sleep cold. Apparently you need to drop your body temp by 10% to get proper sleep. Cheers J
@@joshuadelisle how is it better not to sleep
we all know this is just a excuse to dress up like a kid in the wintertime
we all know that dude with the shorts on in the wintertime (that never works or breaks a sweat)
I got a cheap body warmer last year for my wife and she loved it. The only down size was the charge only lasting a few hrs but I'm thinking I might wear it at home as I work from home and have it plugged in with a USB and save me heating the whole house just to keep me warm! Edit, I've just got it out and started wearing it and I just have the back and collar on heat. I forgot how nice this thing is to wear 😁👍
Awesome well done. Cheers J
Do you think the silicone pads would be to think to install in the foot bed of large motorcycle boots?
As heated handlebar grips / heated seats exist, it should be possible to create heated foot-pegs. Also, as a lot of (southern) Europeans complain about engine heat, it must be possible to jig around with air flow, to warm up the feet and legs of the more northerly riders using engine heat.
@rogerandroid2186 I have heated grips and seats, and the bike also vents hot air on both sides after passing through the radiator. Keeps the legs warm. Feet do get cold, LOL.
I can't see why not. Cheers J
Amazing ideas, just thinking, maybe you cold do that with mattress and try solar panel outside? How effective that could be? Thanks a lot.
I have just bought a gas catalytic heater for my caravan. 800w , no co2 and will run on a 13kg bottle of gas for 300 hrs. Should arrive tomorrow.
If it uses gas and doesn't produce CO2 then what does it produce? Cheers J
If you are going to heat the thing with a candle or such, you could use a teg to drive a pump.
I'd love to see the idea with the sewing tubes into clothes. I think Adam Savage did that for cosplay to keep him cool? I think he used a suit like astronauts use?
Nice. Cheers J
Used one of these for years. You need a decent power bank and your warm all day. No issues with it. Very light weight as well.
You should have made this video instead of all this rambling garbage.
Thanks...
Excellent video. Thank you.
Any recommendations for a low energy dehumidifier?
@@dacawa3917 thank you. I've used a 12L prem-i-air for years. I'll try and get a comparison on others if I can. Cheers J
Dear Josh. Good content, thanks.
I’ve just seen your ‘shorts’ (!😂) on the same subject. So felt obliged to make the same observation here.
Beware of the cheap night rates, they’re only for 6/7 hours. You’ll need to bear that in mind as the daytime rate of these tariffs is (or was when I tried it) a LOT higher than standard. You probably can make it work if you’re very organised, have the necessary amount of batteries (1 didn’t cut it for me) and helps if you’re out all day. (Most pensioners aren’t).
Idea for a video - what exactly does an average household use in electricity?
By that I mean actual appliances. You’d get some ‘participation’ on that one!
A ‘questionnaire’ maybe? I don’t imagine that figures are readily available.eg are there more gas than electric ovens? Do employed people use microwaves more?? Which is more cost effective microwave or gas???
@@JamsODonnell100thank you. those are good points worth investing. Cheers J
Funny, I've been using those silicon pads a lot when winter camping here in Sweden. Lot's of use cases, especially when you get down to -30C
I bet. Cheers J
I have a midrange amazon vest branded as Loowoko (whatever that Ai generated nonsense means), it's like a budget version of the premium one you have, probably polyester filled etc. At £60 including a 10,000mah battery I have to say it's brilliant. In the depths of winter I wear it in the home office plugged into a decent usb wall charger and on battery tinkering in the shed. I would recommend not having them on too high for too long or really sleeping in them though, they can easily cause burns that you wouldn't imediately be aware of (well worth reading into). I have experienced something along these lines where it made my back feel very achey, worth bearing in mind I'm fit and healthy and in my early 30s.
That's a very good point. I'm learning that instead of full body heating, heating just your hands is enough. I think a temp sensor would work well. Cheers J
@@joshuadelisle heating the hands is a good move. I ride motorbikes all year round and suffer from Raynaud's not just from the cold but also vibration, heated grips are a godsend, heated gloves would be even better but they are expensive (as is anything when you stick the words motorcycle in front of it).
In UK split Tariff or Smart meter our electricity prices vary £0.273, £0.138 & £0.099 so heat pump or night stores makes calculations complicated!
Very complicated. Cheers J
you have fluid heating/cooling swetters at your surplus stores. police and military uses them under their body armor
Nice. Cheers J
I loved your videos of smithing, metal working and design. Do you jave plans to do more of those videos in the near future?
Being in sub tropical Qld Australia, I have zero interest in heating, and even less interest in thinking about it when we have humid 30+ days at thos time of year. :)
As a matter of fact yes. I have been commissioned to forge dog head barrier stands for the tower of London. I've got an arc droid to cut the bases out with too. Cheers J
Should you also factor in the life of such a heat pad or battery. Rechargeable batteries fail after a too-short a time, so could be expensive over time.
The new batteries are rated to over 10,000 charge cycles which is a very long time. Depreciation is definitely a good factor though. Cheers J
Re your idea about a silicone tube and heated fluid isn't that similar to what astronauts use? 👍🏻
i have a heated vest that my kids are jealous of but after i received it i started thinking about the potential EMF exposure that cannt be good. i wonder if you can test different products for the degree of electrical effects beyond heat
I wondered the same but you can earth yourself pretty easily if it's something you're worried about. Cheers J
What's the link for your wool jacket? Thanks
I've put a link to the brand in the description for you. Cheers J
as a idea for a project, how about underfloor heating with ether heat pads or diesel heater
Check out the previous video. cheers J
You mentioned water cooling/heating through tubes in vests?
That already exists - AS personal cooling systems for racing drivers!
AND transforming a cooling system into a warming system, SHOULD BE a fairly attainable DIY project!
Definitely. And it's been done for astronauts. Cheers J
smashing work. van and car dwellers will benefit from your research. thank you indeed.
I hope it was helpful to someone. Cheers J
as a idea for a future project, how about underfloor heating with ether heat pads or diesel heater
Watch the last video I did 😉. Cheers J
I've been playing with these for a while, cheaper ones at least and they keep failing. The heated collar is annoying and I cut the wires to the last one. The flashing button on the front is annoying, id rather not stand out. They really need to be close to work - I found putting the "puffer jacket" under another layer works better but then makes the insulation in it useless. Will have to consider a waistcoat style. Nice they have an option to turn off the front as its only my back that gets cold easily. I would look into battery packs with replaceable cells though, since its a shame to keep throwing out poor performing battery banks when cells can be replaced (and the older ones used for situations to suit).
Glad I didn't buy the sock ones then. Got the leggings which I haven't tested as the leggings set cold on a motorcycle doing 70MPH on the motorway at -4C which is the coldest I did a run from Oxford to the NEC "motorcycle live" show at Birmingham. but will at some stage, just annoyed I can't get my leathers over the top of them. Oh, and thanks for adding the links, I really like the set you found, I have some of the really easily ripped ones, OK for riding, but useless for spannering
Well done. Cheers J
ive been using the Milwaukee heated hoodie it has been decent , uses the tool battery so able to out put more volts and amps
I'm tempted to get one but they're also very pricey. Cheers J
you have to carry a Milwaukee battery in your pocket? Damn that sounds uncomfortable.
@@joshuadelisle i had a few of those
better then bosch jackets
@@ruzziasht349 it depends where the pocket is, the problem is they put it in the back
so you have to move the jacket to the side when you sit down-
the small battery does not take up much room, but that doesent last for a work day
and the bigger battery have a very bad shape for your back
i often use another pocket then the one for the purpose, and let the cable go on the outside
bosch have a better placement for the battery
Use a step block for ten minutes an hour, long enough to warm up and not get sweaty?
Good idea. Cheers J
RUclipsr Shug sleeping outdoors in the Northern US in the middle of Winter at -14 degrees Fahrenheit is nuts.
@@BigBlueMotors Luke from outdoorboys eat your heart out lol. Cheers J
Cool I haven't seen these before. I can imagine the option to heat just the back might be quite nice for people working outside with back pain or aches.
@@Pentagathusosaurus definitely. It's very soothing. Cheers J
Really helpful, think I might look into using the pad's to DIY a sort of desk - kotatsu
Nice. An infrared heater maybe ideal for that. Cheers J
