It's interesting. Where I live electricity is really cheap, usually about 0,05 pounds/kWh, so stuff like this has a hard time competing. But I do get curious, if you instead run a generator, take the excess heat through a heat pump to heat your house and sell the power, what would that come out to? Although, I don't know if private citizens can sell electricity over there. Thanks for an interesting video, mate!

If you're worried about o-rings, you can buy strings of the same material, cut it to length and glue it together to form an o-ring. Some manufacturers even sell complete o-ring fabrication kits with everything included. For automatic air relief of the system, you can use a standard air vent valve that's used for hot water heating systems.
@@mattruz9238at least Josh said it was silicone o-rings, not neoprene. I'm fairly sure that silicone is the most temperature resistant of the common O-ring and sealing elastomeres.

Been using this unit for hot water when camping on my ute. Plumbed into my diesel tank for fuel. Heats up my 30 litre hot water tank to 50 degrees in about 10 to 15 minutes. Works really well
yours are some of the most informative unboxing/practical application videos on the internet. Thank you on behalf of everyone who benefits from your videos!
Thank you so much for your kind encouragement. I try my best to keep everything condensed, at a good pace and have as much useful information as possible in the time. Cheers J
@joshuadelisle from my perspective you have succeeded perfectly on all fronts, brilliantly balanced and within the loose story of your shed and yourself. Your delivery as well is excellent, not always the case with you tube which is totally understandable. The only element I would expand on and this is meant for encouragement not negative criticism is the story telling context. As in your life . But I understand that's a fine balance as these are helpful instructional vids and too much of that would distract and that would be shame because, like I say , it feels like you have nailed the format ! (It's just I'm a story teller so I bend towards that side of things) Maybe I should go back a bit in your back catalogue. But , yes, amazing vids , crack on my friend, crack on 😃
@@JCisJDthank you so much. I may ad context to my background again at some point. I've shared my story in earlier videos so it's tedious for regular subscribers to keep talking about that stuff. I have a lot of new subscribers so maybe it's of higher interest. I'll think about it but I don't really like talking about myself. Cheers J
@@joshuadelisle yes, totally get that. I'll look back. Thanks. I came to you through the first diesel heater vid you posted because I baught one for a van project that never got , installed, didn't even fire it up but I will come back to it for sure. So you flag up from time to time but now I'm really appreciating the craft you put into them. Now I've got more time I'll look back through. All the best, keep up the great work 👍
If you press on upper pin on the remote while the heater is running you can scroll and see current battery voltage, temperature of the chamber and more. Great video cheers!
This is why I love your videos, you not only listen to the comments but you investigate them too. Galvanic corrosion is no joke, especially in a hot system. For your heater system, you should try using a radiator for your exhaust. Make sure the top is the in port and the bottom is the out port. As you say make sure the exhaust always flows downwards to remove condensation. Home radiators are so cheap and you don't have to deal with aluminium!
So can we just put the exhaust pipe into one of the 2 water pipe holes in a home water radiator? Then let the exhaust gas find it's way out of the other hole. And while it's inside it's going to warm up the radiator. Is that the idea? Seems straight forward. Just got to remember to allow the moisture condensation water to drip out. And steer the exhaust gas away outside and a certain distance from windows or ventilation fans.
@Google_Does_Evil_Now no I wouldn't use the water pipes for hot gas. Instead I would pass the exhaust pipe though the water tank so the exhaust heats the water. The rest of the system is designed for water only. Cheers J
I was an infrared thermographer during my working years. Spray paint your exhaust tube with some high temperature flat black paint to get an accurate IR temperature measurement. Powerful little heater. Great idea for a hot tub. Good luck. 🤝🤝👍🇺🇸
I like your suggestion to get out and do. I worked in automation, tasked with turning ideas into machines. It was great on someone elses dime. Very satisfying. Now retired, I miss it from time to time. I have to settle on creating vicariously as the tools and materials are too expensive. And I lack problems to solve.
10 thumbs up !! (if I could) This is the gold standard of product reviews particularly for techs, engineers and geeks. The beauty is that just an average Joe will get an education just watching you!.
Your videos are very good and informative, you explain things in a clear easy to understand way. But there is a little but, I can’t understand why a guy like you doesn’t seem to have any proper tools . Thanks for the video I have enjoyed it.
A small detail, glycol has both less heat capacity and heat conductivity than water. Around half. But it does flow better at zero degree Celsius, which is the only benefit to it. Any other benefits are usually due to additives added to glycol solutions. Otherwise, good video as usual, nice breakdown of the pump, appreciate the walkthrough!
Ok, thank you for the tip. Any idea of a more suitable fluid thermally-wise ? In terms of possible interesting alternatives to glycol, here in France it is possible to buy bottles to make your own cooling liquid simply by mixing a concentrated bottle of additives with distilled water. It is way way cheaper, you can add it up after testing a circuit with water and you can concentrate or dilute it according to your freezing conditions.
@@63n0it I've heard of "Water Wetter" for race cars, from memory it allows the water to conduct more heat while being less slippery if there is a spill on a race track but I don't think it has any freezing protection.
One mistake, glycol inhibits heat transfer, not much, but the decrease will be greater with higher glycol concentrations. 30% propylene glycol will decrease heat transfer by around 10%. Also, glycol takes more power to pump, again, not a lot more, but this also increases with higher concentrations.
What a fantastic video! Very detailed and practical! About the cooling system, Water is better than glycol at heat transfer but regular tap water will corrode. That’s why most club race car drivers prefer distilled water in their cooling system as long as they don’t live in an area where water freezes which will cause the engine block to crack.
Depending on the metals used in the burner, you 'might' be able to clean out gunk deposits by soaking it overnight in a concentrated solution of Sodium Hydroxide. Flush with clean water, then place in the oven at ~ 100°C for an hour or two to dry it out.
I’m looking forward to the Bamboo Labs X1 review - I trust your opinion and judgement more than any other; the Webasto copy content today was excellent as always and it’s fantastic to see your subscriber numbers up at 225k. And to think in the early days you had just a handful of subscribers. Keep it coming Joshua 👍
Thank you so much. I appreciate your long term support. I have a lot of practical ideas for the printer and also got some interesting filaments including carbon fibre and ASA. Cheers J
Hi I fitted the same unit on my 900 lt hot tub last june and its great so much quicker to heat up, I piped the tubs drain to the inlet and then fitted the return on a stand over the top of the tubs wall this way I could leave the tubs controls in place. I also have installed a egr on the inlet this makes a big difference on temp rise over time. Great video
@joshuadelisle That's the only problem with this model but when the hot tub is at temperature I found that a short boost one hour before use was all it needed.
This thing reminds me of about 25 years ago a buddy's dad picked up an ex railroad pickup and it had a diesel cabin/engine preheater in it. It was intended for the rail crews to be able to sit/sleep in the truck in the coldest weather but not have to leave the engine running. It kept the cabin toasty and the engine block and oil nice and warm. We pulled the thing out and ended up installing it in his shed for heat. It used 12V DC and a 1 gallon diesel tank (would last well over 24hrs) and the truck's heater core. A 12V fan on the heater core made this thing pump out the heat. It would run off a car battery for hours without thinking about it.
Thanks for a very informative video. I am in the process of building a 68ft barge, and was indecisive about what form of heating to use. As my boat is going to be fully electric, I wanted a secondary form of heating but haven't made a decision on the form of delivery until i watched your video. You've given me a lot to ponder on. Thankyou. Look forward to your next one.
if you use your preferred method of making a casting or molding , ( powder, 3d printing, blue stuff) you can make a reusable mold and make replacement o-rings and seals using silicone with the proper heat resistance, they wont be quite as good quality but since you can make as many as you want it usually evens out. i always find this useful for weird shaped gaskets like the one on the back plate. also I'm sure for where you are the use of biodiesel doesn't make sense for financial reasons but it might be worth seeing what the efficiency of using it is because it is easier to make in emergencies than refining your own petrochemical diesel.
@@joshuadelisleI used to make my own biodiesel years ago. Thinking with these heaters might be ok to not bother washing it and just leave the methanol residue in it. If the fuel pipe is switched to silicone with maybe a ptfe hard plastic outer (I probably wouldn’t bother myself as I’m still 5 years in on the crappy green fuel lines and heater lives outside in all weather) anyway, yeah, I know bio diesel is fine at 50/50 with white diesel but it’s 10 year old stuff I had from back in the day and it’s washed. Ps, it won’t run on 100% unless you want to create a battleship grade smoke screen. ( never tried a twin tank system though on heater ( landrover yes)
FYI don’t use stainless steel next to aluminium with water as galvanic action is strong. Used to scuba dive with a Nikons us camera, the brackets mixed the two and despite loads of grease and washing carefully after each dive the 40 minute dives were enough to destroy the aluminium part where they touched.
Please do the build video of the hot tub. I have one half built from an IBC container. I'm thinking of scrapping that off though and using 2 tin baths on decking for me and my wife instead. It would be easier to keep clean, less water usage and when not in use I'd be able to move it all. I would like a system that keeps the water warm though so we can spend an hour or two in there with a glass of wine. But either way, what ever you come up with will be helpful for my own endeavours. Many thanks for bringing these heaters to my attention. It looks like the answer to my problems has just fallen in my lap!
Thank you. I had the idea to use an IBC too but also came to the conclusion that a regular bath is more cost effective and can still use jacuzzi jets. I've got 4 kids though that want space to splash around. Cheers J
Another thought provoking video! ...... Well done that man! As per electrolytic corrosion, I do not know how glycol affects things but you can get a corrosion inhibitor for normal central heating systems. This is designed to stop electrolytic corrosion between Aluminium, Copper and Steel ..... so should be a good thing in your setup! Given the direction our world is going (especially here in the UK) these are all great tools to have in your kit in order to enable if not grid free living then a reduced dependence on the grid. Even the annoying overstating of capacity can be forgiven for this kind of kit ...... Brilliant!
FYI with a stainless steel water to gas heat exchanger, you can extract even more heat from the exhaust of the unit and raise it's efficiency past 80%, and this part likely would cost you $60-$150 from your favourite websites.
Thanks for the vid! don't forget in the 30 minutes of run time, that un-insulated water container would have lost a good amount to the air, especially as it was cold in your workshop!
A terrific review - thanks for editing out the minutae of the taking out bolts one-by-one, etc. It's wonderful watching someone work with their hands and passing along their tinkering projects. I'm sure that someone could find many uses for this heating system. Unfortunately, as another commenter observed, our fuel costs are too high in Canada to make this cost effective. Keep up the great work, Joshua!
Oh no , wish I knew about this unit before I ordered my Wippro diesel heater, want to heat my patio with it to supplement my St Croix pellet stove . The floor is 1- 1/2 “ thick patio pavers , that heater would be nice to use with pex tube to heat the floor 😢 Just subscribed, watched a few of you earlier videos and really appreciate your attention to detail with explanations as you go. Along with converting Celsius to Fahrenheit and metric to inches.
I bought a webasto to fit to my land rover - have had it in the shed for over a year now cause I just can't bring myself to work on the car now that it's running somewhat okay at the minute. This is a good alternative use
Thankyou for making these videos. I just started watching your videos. Im on a few acres in the Australian bush and im trying to learn similar stuff as l power off solar and now we're broke but l deal with scrap so l have access to bits and pieces. Keep going. You're important for these times.
Thank you. I've been broke for a long time and so I've had to learn to be resourceful. I like it that I can now afford to test new things I would otherwise be Interested in using to save money but wasn't sure about the return on investment. I'm only too glad my research is able to help people who were like me... Broke. Cheers J
Awesome info, thank you. just one minor bit of feedback, an antifreeze makes sense BUT water is a better heat transfer medium than glycol (or pretty much anything else). This is why, even in power stations where money is a trivial consideration, plain old water is still the heat transfer fluid of choice.
Thanks for this. I always find your videos interesting. This time I've actually ordered one of these water heaters on your recommendation for my own project. I look forward to receiving it and starting work.
Wow, again such a nice video! I would LOVE to see a series optimizing this heating system, like you did with the air diesel heating system. Maybe using an insulated water storage with a two-way exhaust. When the room temperature drops below a certain point, the exhaust heat could be stored in a sand bank. Otherwise, the exhaust heat could go through an EGR cooler and transfer the heat into the insulated tank. Maybe it's a bit useless, but I love useless things :) Thanks for making this video! Greetings from Germany!
I love your videos. I found this product on aliexpress and was intrigued by it.. now you have made one of your indepth videos, all my questions are answered. Keep it up.
Wow, an amazing tear down and demonstration, can’t fault it. A solar panel through charging your battery pack should see the system through the day heating your hot tub. Thanks for sharing.
Thinks for the quick follow up. I just noticed your channel. I saw the video with the installation of the radiator. Usually the follow up video is a year away!!! LOL
Great video I’m exploring different ways to heat water on my narrowboat before I move onboard, very efficient and not too big 👍 I think my calorifier has connectors that will connect directly to it thank you👌
THANK YOU!!!! I've bee watching all your videos and was about to pull the trigger on a hot water heater for my truck. barely anyone is testing the Chinese hydronic heaters 🙏
A few days ago I was thinking about this water heater and had some doubts about its efficiency for my CV installation. Thank you for the video and math after it. Looks it worth trying for this amount of money (I found it for 145 euro)
Another cracking video - that laugh was absolutely hysterical! 😆😂 I wish there were more creators like you putting out this kind of high quality content. Selfishly, though, I’d love to see you uploading more too. Have a good Christmas & keep up the great work! 😁
How exciting... With Ai steaming along we will all be able to make things a lot easier... I live off grid in the hills and this will definitly help me treat my water I get from the creek... at the moment it costs me about AU$5 in unleaded to use my 8kva generator to get 30 litres of water boiling for 10 minutes to make it safe... I too am now dreaming of a hot tub. Thanks heaps brother Josh.
@ no need. Need to sterilise it so have to boil it for close to ten minutes and then can use gravity filter that keeps all the beneficial elements. You could use charcoal and uv if you wanted to do it that way. Or just do your reverse osmosis… however you feel best.
In an emergency you could use a silicone sealant to make/repair the 'O' rings most standard sealants are good for 250°C and the high temperature sealant is good for 300°C. I was impressed with the units build quality, sorry, once an engineer always an engineer, and the manual looked really detailed. The ability to remotely start and stop the heater is fantastic as quite often my finishing time would vary enormously. Running on glycol through an indirect water tank/heating coil is a bonus, as it should prolong the life of the unit. As you said reclaiming the heat lose through the exhaust is helpful. Our heating is all gas from the tank in the garden, the price of this has virtually doubled in recent times, so having a cheaper method of producing hot water can only be a win-win situation. Thank you for yet more ways towards a more efficient lifestyle, it is greatly appreciated. Take care and be well, regards to all 👍
Thank you so much. I think having this integrated in the current heating system gives the option depending on market price and availability. Both oil, gas and electric are up and down depending on demand and politics. Cheers J
Great video, I love it when you explore alternative and affordable ways of heating. I'd only add that saying the unit is only 3.2kW isn't quite correct. You should take into account that your system has a lot of losses. Not only on the exhaust but also the water dissipating heat onto the environment,. In an ideal world, you should have the water in a closed system that doesn't lose heat to measure the efficiency. Edit: Also, since kWh is a measure of energy, W is a measure of power, and we know power is energy divided per time; saying kWh/hour would simply be kW. Another useful thing to understand is that 1 W is the same as 1 J/s, 1 kW equals 1 kJ/s, 1 Ws (watt * second) is 1 J, 1 Wh is 3600 J as 1 hour is 3600 seconds, 1 kWh is 3600 kJ, so on and so forth. Working with measurements of power and energy would confuse me so much until I learned this, so I hope this can help you🙂
Great video :) btw, i believe those metal clips on the connecters, does not need to come off, they are similar to older auto style connecters. just press firmly on the metal clip and it unlocks, less chance of losing it :)
Hi joshua! I really like your videos please keep going you are great as well the content. I happened to notice at 8.13 of this video, the silicon ring was pinched. I think a bit of silicon grease around the cilinder prior to” force it” might have prevented it. Ciao man!
excellent presentation! I'm off grid and in a "cabin" where hot air ducting from a diesel heater is challenging....and hydronic heating for ancillary space would be possible. I've looked at small diesel boilers but the expense and complexity is too high. Thank you for this and i hope that you might at some point develop blower coil space heating concepts.
Hi, maybe not ideal for you but for special rubber or silicone gaskets that are impossible to find, I use a 3d printer to make molds and cast it with loctite silicone blue or black, of course this can work with any silicone sealant but loctite curing time is well documented (it can take several days, the thicker, the longer) and also reliable. Definitely not the simplest/fastest solution but better than not fixing something because of stupid gasket not available (or prohibitively expensive) ....
I really appreciate your experiments with these heaters, I placed one in my garage two years ago, and its still running well. No doubt this deisel water heater works well, the real question is, how good is the China English manual? 😅
Awesome detailed review! I would be interested in seeing a TDS total dissolved solids, metre reading of the water before and after to see if it is adding any significant amount of contaminants.
At the beginning you suggested it could be combined into a central heating and then separately mentioned galvanic corrosion, hopefully those listening actually paid attention to that. If someone wants to do that, then you can get plated heat exchangers which are neutral to the other metals.
@@BobHannent you can isolate it with calorifier. So it's not an issue if you know what to use. Also there are inhibitors to counteract the corrosion. It's just not as simple as hooking it up. Cheers J
I think the reason for the missing heat sensor gasket is the anticipated heat expansion, which may cause pressure to occur between the facing surfaces of the two involved parts.
Believe nothing, evidence everything, great policy and the only way is to get your hands dirty, this is when you start learning, not at school. Top notch as per usual Josh, im not looking to buy one but i do like professional approaches to manufacturers claims under test.
Great video. Been waiting for this product to be released. I've fitted quite a few of the genuine version of this. Pleased to see a affordable version lol. I plumb them into a calorifier and use them to heat multiple radiators too, on narrowboats. You may want to use a closed loop heat exchanger set up for your hot tub. That way they heater will be run at operating temperature. Plus once the unit hits 80somthing degrees it will 'back off' to half power. Which has a beneficial effect on fuel and power consumption . Firstly I'd recommend upgrading the pump to a genuine one as they are completely silent and same goes with the exhaust. The marine silencers are expensive but the best. Also be careful not to overcool it as they're a bit more sensitive compared to the blow heaters. Good luck on your mission. From an un educated tinkerer like yourself. Peace ✌️
Fantastic presentation. New subscriber.. one point, though I don't know how important it is. As the water heat up the heat transfer rate between it and the chamber gets less efficient. I.e. delta T decreases and so does heat transfer. I have no idea how much, but a rise in exhaust temperature proportional to rise in water may give a clue. Anyway, recovering exhaust heat would probably mostly negate this loss.
What a price compared to the Webasto and Eberspacher very nice-looking alloy casts, it appears the Chinese are getting better at quality control. The only thing I noticed was the flow of water is a lot less than my Webasto thermo top. There are specific heat exchangers available when used in a glycol system to heat the air, or indeed hot water for showers or washing. Quite a lot of motorhomes have the same system. Nice to see you warn of the copper pipe's galvanic action also not to be used for exhausts because of poisonous fumes
Just finished up on a Webasto Thermotop Evo setup. Running underfloor heating. Don’t work as well as hoped requires the unit to run at full speed for nearly an hour to get the whole floor upto temp and unit to idle down. Where using rad’s only takes around 20 minutes to heat the whole system. The amount of diesel used on the UFH is about 4 times the amount of rads. You say you can’t use Cooper & Ali together. My system has been running for 15 years. I’ve not seen and corrosion of Ali parts whatsoever I do use an inhibitor for extra protection. A friend of mine has a wood fired hottub and thinking of doing the same thing. Preheat the water so you can just top it off with wood once you get there
12:35 Glycol will not get you better efficiency. As a matter of fact, the efficiency will be worse if you use glycol. Usually glycol is mixed with water to stop it from freezing. Even if you don't use pure glycol but a 1:1 mixture with water, the specific heat capacity of the mixture is about 75% of what it would be if you used pure water. This is assuming you're using ethylene glycol.
I just bought one 3 days ago from Banggood, have no idea what I’m going to use it for but if I have one I will find something to do with it. Shame max run time is 1 hr on the version I ordered but at £200 delivered it’s a no brainer. I hope hcalory come out with a service kit for the unit, seals etc.
looks super cool! Realy handy that it has a build in heat exchanger! Seems like you could squeeze some more efficientsy out of it by some how capturing the heat produced from the exhaust!
@@joshuadelisle Those £60 automotive EGR units like you showed in the last vid are great. The exhaust is cool enough to hold your hand in front of! I'm recovering over 400W on the H4 setting on my air heater.
Love the review! Granted this is only a copy of Webasto’s design but it is still very nicely done. The only option I wish it had was a temperature control, in a large storage tank turn on at 5^C and turn off at 10^C, or in a small tank for hot water storage. I’m sure I can figure out how to make it do that with an Arduino.
Nice test! I think the efficiency is a bit higher since you are losing quite a bit of energy to the air and workbench ( see the flir image), you would get a more accurate reading if you insulated the container and hoses :)
very true but for a practical output there will always be losses in the whole system so I think the calculation it is still relavent. depending on wether the pipes are insulated or not, it could be far worse. cheers J
Yeah, at last a test of one of these ... And top-notch review ... How great ! Any idea of what chinese brands to prefer or avoid ? In terms of air heaters, i have a bad experience with a 5kW Vevor and excellent yet time-limited with 2kW and 5kW FDIK ... The controls and possibly the pumps seem different from one to another ...
@@63n0it thank you. The brand it self isn't important, they're just a name. Knowing who manufactures it is the key because most brands use the same manufacturer. Hcalory has terrible diesel heaters but this water version is fantastic but made by a different factory. Cheers J
@@joshuadelisle Thank you. How do you figure out the factory of an existing and/or of a desired product ? And how to figure out the good factories, then ?
Another quality video 💪👌 I like what you said. „ you don’t need always certificate to do things „ Thanks for your hard work 👍 all the best for you and your family
Looks like a nice bit of kit. Imagine hooking that up with a hot water cylinder. Could quite easily set the unit outside and run some pipes from the water pump.
Why not use 240v inverter? Cheap, and you don't run out when you need it most ( aka sods law) plus, you don't want an abrupt stop, you want the cooldown run...🥂🥂🥂🥂 Great video, as always👍👍👍👍👏👏👏👏
A british pence is about a us penny,and kerosene is hard to find locally since everything has gone to either diesel or natural gas here,but it can be found within 1 hours drive and wouuld be well worth throwing an empty drum in the trucks bed before heading out of town with that for a water heater..
When sealing up things to heat (with in reason) clear silicone works really well against heat, just make sure it has gone off before exposing to heat. Been using it on car exhaust parts for years. I realised how good it was after tying to burn some off a piece of glass, it did come off the class. . . or should I say the glass came off it!
I commented last time with the idea of a plate heat exchanger, but going directly to water from the source is a much better solution indeed. A lot of heat pump installs use a buffer vessel combination with zone heating. Running the exhaust through the buffer as well would make this pretty efficient, and compatible with "ordinary" heating solutions! Looking forward to your ideas :)!
LOL love your comment about qualifications. I would love to see how this would work heating a couple of radiators as we live in a 150yr old stone cottage with 0 heating other than a coal fire and 1 radiator. We used to have a hot tub and our electric bill increased nearly £200 per month and that was in 2015, I dread to think what that would be now, but I miss my hot tub lol, this just might be the answer as the max recommended temp for the tub is about 39c. Definitely like to see any more on these heaters. Just found your channel a few days ago, but have seen diesel heaters used in Alaska to heat hen houses etc. Oh and I would escape to Alaska in heart beat. I noticed in a previous video you did a segment on climate change, Totaly agree with your thinking! Thanks for an interesting and educational channel!
regarding accessing the filter gauze I'm not sure but it looked like it was held in by a spring clip which might be accessed by a long nose pliers. Just a thought. Great video thanks.
I really hope this information is useful to someone and I look forward to hearing your thoughts on it.

What does AWCB mean after your name?
BTW I really enjoyed the video!
It's interesting.
Where I live electricity is really cheap, usually about 0,05 pounds/kWh, so stuff like this has a hard time competing.
But I do get curious, if you instead run a generator, take the excess heat through a heat pump to heat your house and sell the power, what would that come out to?
Although, I don't know if private citizens can sell electricity over there.
Thanks for an interesting video, mate!

I was in the bottom class for maths and left school with very low exam results I went on to become a driller on an oil rig working out dozens of complicated mathematical equations for flow rates formation pressure etc .I've always maintained you learn easier if your interested in a subject
Definitely. When you need maths as a tool to complete a job that has your interest, suddenly it makes sense. Cheers J
That and kids are dumb.

If you're worried about o-rings, you can buy strings of the same material, cut it to length and glue it together to form an o-ring. Some manufacturers even sell complete o-ring fabrication kits with everything included. For automatic air relief of the system, you can use a standard air vent valve that's used for hot water heating systems.
Nice. cheers J
Hight Temp RTV would likely work also as long as you were careful with application.
I use Loctite o ring kit....McMaster Carr.... the neoprene rubber would be equal or better than the urethane that you are using.
@@mattruz9238at least Josh said it was silicone o-rings, not neoprene. I'm fairly sure that silicone is the most temperature resistant of the common O-ring and sealing elastomeres.
Very nice tips. How great is the internet, sometimes. THANK YOU !

Been using this unit for hot water when camping on my ute. Plumbed into my diesel tank for fuel. Heats up my 30 litre hot water tank to 50 degrees in about 10 to 15 minutes. Works really well
@@rylanbrowne5658 nice. Cheers J
yours are some of the most informative unboxing/practical application videos on the internet. Thank you on behalf of everyone who benefits from your videos!
Thank you so much. Cheers J
Your videos are so clear so well edited and designed.
Thank you so much for your kind encouragement. I try my best to keep everything condensed, at a good pace and have as much useful information as possible in the time. Cheers J
@joshuadelisle from my perspective you have succeeded perfectly on all fronts, brilliantly balanced and within the loose story of your shed and yourself. Your delivery as well is excellent, not always the case with you tube which is totally understandable. The only element I would expand on and this is meant for encouragement not negative criticism is the story telling context. As in your life . But I understand that's a fine balance as these are helpful instructional vids and too much of that would distract and that would be shame because, like I say , it feels like you have nailed the format ! (It's just I'm a story teller so I bend towards that side of things) Maybe I should go back a bit in your back catalogue. But , yes, amazing vids , crack on my friend, crack on 😃
@@JCisJDthank you so much. I may ad context to my background again at some point. I've shared my story in earlier videos so it's tedious for regular subscribers to keep talking about that stuff. I have a lot of new subscribers so maybe it's of higher interest. I'll think about it but I don't really like talking about myself. Cheers J
@@joshuadelisle yes, totally get that. I'll look back. Thanks. I came to you through the first diesel heater vid you posted because I baught one for a van project that never got , installed, didn't even fire it up but I will come back to it for sure. So you flag up from time to time but now I'm really appreciating the craft you put into them. Now I've got more time I'll look back through. All the best, keep up the great work 👍
If you press on upper pin on the remote while the heater is running you can scroll and see current battery voltage, temperature of the chamber and more. Great video cheers!
Good tip. Cheers J
This is why I love your videos, you not only listen to the comments but you investigate them too. Galvanic corrosion is no joke, especially in a hot system. For your heater system, you should try using a radiator for your exhaust. Make sure the top is the in port and the bottom is the out port. As you say make sure the exhaust always flows downwards to remove condensation. Home radiators are so cheap and you don't have to deal with aluminium!
Thank you so much. Cheers J
So can we just put the exhaust pipe into one of the 2 water pipe holes in a home water radiator? Then let the exhaust gas find it's way out of the other hole. And while it's inside it's going to warm up the radiator. Is that the idea?
Seems straight forward. Just got to remember to allow the moisture condensation water to drip out. And steer the exhaust gas away outside and a certain distance from windows or ventilation fans.
@Google_Does_Evil_Now no I wouldn't use the water pipes for hot gas. Instead I would pass the exhaust pipe though the water tank so the exhaust heats the water. The rest of the system is designed for water only. Cheers J
watch out for backpressure .... might mess with the burning
I was an infrared thermographer during my working years. Spray paint your exhaust tube with some high temperature flat black paint to get an accurate IR temperature measurement.
Powerful little heater. Great idea for a hot tub. Good luck. 🤝🤝👍🇺🇸
Thank you. Cheers J
Get a water to water heat exchanger, don’t have chlorine full hot tub water coming anywhere near your heat source, it’ll eat through everything
I like your suggestion to get out and do. I worked in automation, tasked with turning ideas into machines. It was great on someone elses dime. Very satisfying.
Now retired, I miss it from time to time. I have to settle on creating vicariously as the tools and materials are too expensive. And I lack problems to solve.
10 thumbs up !! (if I could) This is the gold standard of product reviews particularly for techs, engineers and geeks. The beauty is that just an average Joe will get an education just watching you!.
@@rockofalethia9387 you're very kind. Cheers J
Your videos are very good and informative, you explain things in a clear easy to understand way. But there is a little but, I can’t understand why a guy like you doesn’t seem to have any proper tools . Thanks for the video I have enjoyed it.
Thank you. Its because im a cheap skape and/or too lazy to find the right tool. cheers J
A small detail, glycol has both less heat capacity and heat conductivity than water. Around half. But it does flow better at zero degree Celsius, which is the only benefit to it. Any other benefits are usually due to additives added to glycol solutions. Otherwise, good video as usual, nice breakdown of the pump, appreciate the walkthrough!
Thank you. Cheers J
In some states it is still sold at the pump .
I saw it in Portland , Or two years ago but only at one station .
Ok, thank you for the tip. Any idea of a more suitable fluid thermally-wise ? In terms of possible interesting alternatives to glycol, here in France it is possible to buy bottles to make your own cooling liquid simply by mixing a concentrated bottle of additives with distilled water. It is way way cheaper, you can add it up after testing a circuit with water and you can concentrate or dilute it according to your freezing conditions.
"But it does flow better at 0⁰c than water" it also doesn't expand and crack anything you put it in if left in that temperature for long periods 🤣
@@63n0it I've heard of "Water Wetter" for race cars, from memory it allows the water to conduct more heat while being less slippery if there is a spill on a race track but I don't think it has any freezing protection.
One mistake, glycol inhibits heat transfer, not much, but the decrease will be greater with higher glycol concentrations. 30% propylene glycol will decrease heat transfer by around 10%. Also, glycol takes more power to pump, again, not a lot more, but this also increases with higher concentrations.
What a fantastic video! Very detailed and practical! About the cooling system, Water is better than glycol at heat transfer but regular tap water will corrode. That’s why most club race car drivers prefer distilled water in their cooling system as long as they don’t live in an area where water freezes which will cause the engine block to crack.
Depending on the metals used in the burner, you 'might' be able to clean out gunk deposits by soaking it overnight in a concentrated solution of Sodium Hydroxide. Flush with clean water, then place in the oven at ~ 100°C for an hour or two to dry it out.
interesting. cheers J
In these current times all of your videos are super useful and magnificently informative 👍

Hi I fitted the same unit on my 900 lt hot tub last june and its great so much quicker to heat up, I piped the tubs drain to the inlet and then fitted the return on a stand over the top of the tubs wall this way I could leave the tubs controls in place. I also have installed a egr on the inlet this makes a big difference on temp rise over time. Great video
Nice one. Did you have any issues with the controller timings, some say it only heats for one hour and so need to keep re setting? Cheers J
@joshuadelisle That's the only problem with this model but when the hot tub is at temperature I found that a short boost one hour before use was all it needed.
This thing reminds me of about 25 years ago a buddy's dad picked up an ex railroad pickup and it had a diesel cabin/engine preheater in it. It was intended for the rail crews to be able to sit/sleep in the truck in the coldest weather but not have to leave the engine running. It kept the cabin toasty and the engine block and oil nice and warm. We pulled the thing out and ended up installing it in his shed for heat. It used 12V DC and a 1 gallon diesel tank (would last well over 24hrs) and the truck's heater core. A 12V fan on the heater core made this thing pump out the heat. It would run off a car battery for hours without thinking about it.
Nice. cheers J
Modifying this for a home radiator would be awesome for a shop/garage
Mini expansion vessel and prv amd your there 600x1200 double rad or cleverer would be car radiator and quiet fan.in a cabinet.
Thanks for a very informative video. I am in the process of building a 68ft barge, and was indecisive about what form of heating to use. As my boat is going to be fully electric, I wanted a secondary form of heating but haven't made a decision on the form of delivery until i watched your video. You've given me a lot to ponder on. Thankyou. Look forward to your next one.
Thank you so much. Cheers J
if you use your preferred method of making a casting or molding , ( powder, 3d printing, blue stuff) you can make a reusable mold and make replacement o-rings and seals using silicone with the proper heat resistance, they wont be quite as good quality but since you can make as many as you want it usually evens out. i always find this useful for weird shaped gaskets like the one on the back plate. also I'm sure for where you are the use of biodiesel doesn't make sense for financial reasons but it might be worth seeing what the efficiency of using it is because it is easier to make in emergencies than refining your own petrochemical diesel.
good idea. cheers J
@@joshuadelisleI used to make my own biodiesel years ago. Thinking with these heaters might be ok to not bother washing it and just leave the methanol residue in it. If the fuel pipe is switched to silicone with maybe a ptfe hard plastic outer (I probably wouldn’t bother myself as I’m still 5 years in on the crappy green fuel lines and heater lives outside in all weather) anyway, yeah, I know bio diesel is fine at 50/50 with white diesel but it’s 10 year old stuff I had from back in the day and it’s washed. Ps, it won’t run on 100% unless you want to create a battleship grade smoke screen. ( never tried a twin tank system though on heater ( landrover yes)
FYI don’t use stainless steel next to aluminium with water as galvanic action is strong. Used to scuba dive with a Nikons us camera, the brackets mixed the two and despite loads of grease and washing carefully after each dive the 40 minute dives were enough to destroy the aluminium part where they touched.
I'll look into it. Thank you. Cheers J
Please do the build video of the hot tub. I have one half built from an IBC container. I'm thinking of scrapping that off though and using 2 tin baths on decking for me and my wife instead. It would be easier to keep clean, less water usage and when not in use I'd be able to move it all. I would like a system that keeps the water warm though so we can spend an hour or two in there with a glass of wine. But either way, what ever you come up with will be helpful for my own endeavours.
Many thanks for bringing these heaters to my attention. It looks like the answer to my problems has just fallen in my lap!
Thank you. I had the idea to use an IBC too but also came to the conclusion that a regular bath is more cost effective and can still use jacuzzi jets. I've got 4 kids though that want space to splash around. Cheers J
Happy New Year Joshua 🎉
I can now have a bath in the wilderness with this awesome Chinese gadget cheers Joshua 👍
Another thought provoking video! ...... Well done that man!
As per electrolytic corrosion, I do not know how glycol affects things but you can get a corrosion inhibitor for normal central heating systems. This is designed to stop electrolytic corrosion between Aluminium, Copper and Steel ..... so should be a good thing in your setup!
Given the direction our world is going (especially here in the UK) these are all great tools to have in your kit in order to enable if not grid free living then a reduced dependence on the grid.
Even the annoying overstating of capacity can be forgiven for this kind of kit ...... Brilliant!
Thank you. I totally agree. Cheers J
FYI with a stainless steel water to gas heat exchanger, you can extract even more heat from the exhaust of the unit and raise it's efficiency past 80%, and this part likely would cost you $60-$150 from your favourite websites.
Thanks for the vid! don't forget in the 30 minutes of run time, that un-insulated water container would have lost a good amount to the air, especially as it was cold in your workshop!
A terrific review - thanks for editing out the minutae of the taking out bolts one-by-one, etc. It's wonderful watching someone work with their hands and passing along their tinkering projects. I'm sure that someone could find many uses for this heating system. Unfortunately, as another commenter observed, our fuel costs are too high in Canada to make this cost effective. Keep up the great work, Joshua!
Thank you. bio deiesel maybe a better option for you. cheers J
Oh no , wish I knew about this unit before I ordered my Wippro diesel heater, want to heat my patio with it to supplement my St Croix pellet stove . The floor is 1- 1/2 “ thick patio pavers , that heater would be nice to use with pex tube to heat the floor 😢 Just subscribed, watched a few of you earlier videos and really appreciate your attention to detail with explanations as you go. Along with converting Celsius to Fahrenheit and metric to inches.
I bought a webasto to fit to my land rover - have had it in the shed for over a year now cause I just can't bring myself to work on the car now that it's running somewhat okay at the minute.
This is a good alternative use
@@TheTacticalHaggis I understand how you feel. Cheers J
Thankyou for making these videos. I just started watching your videos. Im on a few acres in the Australian bush and im trying to learn similar stuff as l power off solar and now we're broke but l deal with scrap so l have access to bits and pieces. Keep going. You're important for these times.
Thank you. I've been broke for a long time and so I've had to learn to be resourceful. I like it that I can now afford to test new things I would otherwise be Interested in using to save money but wasn't sure about the return on investment. I'm only too glad my research is able to help people who were like me... Broke. Cheers J
Awesome info, thank you. just one minor bit of feedback, an antifreeze makes sense BUT water is a better heat transfer medium than glycol (or pretty much anything else).
This is why, even in power stations where money is a trivial consideration, plain old water is still the heat transfer fluid of choice.
Thanks for this. I always find your videos interesting. This time I've actually ordered one of these water heaters on your recommendation for my own project. I look forward to receiving it and starting work.
@@mustaphapint thank you so much. All the very best. Cheers J
Wow, again such a nice video! I would LOVE to see a series optimizing this heating system, like you did with the air diesel heating system. Maybe using an insulated water storage with a two-way exhaust. When the room temperature drops below a certain point, the exhaust heat could be stored in a sand bank. Otherwise, the exhaust heat could go through an EGR cooler and transfer the heat into the insulated tank. Maybe it's a bit useless, but I love useless things :) Thanks for making this video! Greetings from Germany!
This would be amazing for solar panel cleaning jobs. So many ideas
That's a great idea. Cheers J

How exciting... With Ai steaming along we will all be able to make things a lot easier... I live off grid in the hills and this will definitly help me treat my water I get from the creek... at the moment it costs me about AU$5 in unleaded to use my 8kva generator to get 30 litres of water boiling for 10 minutes to make it safe... I too am now dreaming of a hot tub. Thanks heaps brother Josh.
Thank you. Cheers J
Why would you not use a reverse osmosis water filter with a low volumn high pressure12V pump?
@ no need. Need to sterilise it so have to boil it for close to ten minutes and then can use gravity filter that keeps all the beneficial elements. You could use charcoal and uv if you wanted to do it that way. Or just do your reverse osmosis… however you feel best.
In an emergency you could use a silicone sealant to make/repair the 'O' rings most standard sealants are good for 250°C and the high temperature sealant is good for 300°C. I was impressed with the units build quality, sorry, once an engineer always an engineer, and the manual looked really detailed. The ability to remotely start and stop the heater is fantastic as quite often my finishing time would vary enormously. Running on glycol through an indirect water tank/heating coil is a bonus, as it should prolong the life of the unit. As you said reclaiming the heat lose through the exhaust is helpful. Our heating is all gas from the tank in the garden, the price of this has virtually doubled in recent times, so having a cheaper method of producing hot water can only be a win-win situation. Thank you for yet more ways towards a more efficient lifestyle, it is greatly appreciated. Take care and be well, regards to all 👍
Thank you so much. I think having this integrated in the current heating system gives the option depending on market price and availability. Both oil, gas and electric are up and down depending on demand and politics. Cheers J
Thanks for the encouraging video I picked up one of these last spring and have been planning to install it into my sailboat.
Nice. Cheers J
Great video, I love it when you explore alternative and affordable ways of heating. I'd only add that saying the unit is only 3.2kW isn't quite correct. You should take into account that your system has a lot of losses. Not only on the exhaust but also the water dissipating heat onto the environment,. In an ideal world, you should have the water in a closed system that doesn't lose heat to measure the efficiency.
Edit:
Also, since kWh is a measure of energy, W is a measure of power, and we know power is energy divided per time; saying kWh/hour would simply be kW. Another useful thing to understand is that 1 W is the same as 1 J/s, 1 kW equals 1 kJ/s, 1 Ws (watt * second) is 1 J, 1 Wh is 3600 J as 1 hour is 3600 seconds, 1 kWh is 3600 kJ, so on and so forth.
Working with measurements of power and energy would confuse me so much until I learned this, so I hope this can help you🙂
Great video :) btw, i believe those metal clips on the connecters, does not need to come off, they are similar to older auto style connecters. just press firmly on the metal clip and it unlocks, less chance of losing it :)
Thank you. You're right, I feel silly now. Cheers J
cables tied in a figure 8 shape is fine, its when you coil them tightly in a circle youll get problems if at a high amperage.
@@Simon-ui6db you're probably right but it's not good practice either way. Cheers J
Hi joshua! I really like your videos please keep going you are great as well the content. I happened to notice at 8.13 of this video, the silicon ring was pinched. I think a bit of silicon grease around the cilinder prior to” force it” might have prevented it. Ciao man!
excellent presentation! I'm off grid and in a "cabin" where hot air ducting from a diesel heater is challenging....and hydronic heating for ancillary space would be possible. I've looked at small diesel boilers but the expense and complexity is too high. Thank you for this and i hope that you might at some point develop blower coil space heating concepts.
Thank you so much. I'll look into it. Cheers J
Hi, maybe not ideal for you but for special rubber or silicone gaskets that are impossible to find, I use a 3d printer to make molds and cast it with loctite silicone blue or black, of course this can work with any silicone sealant but loctite curing time is well documented (it can take several days, the thicker, the longer) and also reliable. Definitely not the simplest/fastest solution but better than not fixing something because of stupid gasket not available (or prohibitively expensive) ....
Joshua 👍 only discoverd you a short while ago ... love all your presentions ... thankyou & more please.
@@David-zo7fb thank you so much. Lots to come. Cheers J
I really appreciate your experiments with these heaters, I placed one in my garage two years ago, and its still running well. No doubt this deisel water heater works well, the real question is, how good is the China English manual? 😅
Thank you. The manual is actually very good on this one. Lots more to come. Cheers J
Awesome detailed review! I would be interested in seeing a TDS total dissolved solids, metre reading of the water before and after to see if it is adding any significant amount of contaminants.
At the beginning you suggested it could be combined into a central heating and then separately mentioned galvanic corrosion, hopefully those listening actually paid attention to that.
If someone wants to do that, then you can get plated heat exchangers which are neutral to the other metals.
@@BobHannent you can isolate it with calorifier. So it's not an issue if you know what to use. Also there are inhibitors to counteract the corrosion. It's just not as simple as hooking it up. Cheers J
I think the reason for the missing heat sensor gasket is the anticipated heat expansion, which may cause pressure to occur between the facing surfaces of the two involved parts.
Believe nothing, evidence everything, great policy and the only way is to get your hands dirty, this is when you start learning, not at school.
Top notch as per usual Josh, im not looking to buy one but i do like professional approaches to manufacturers claims under test.
Thank you so much. Cheers J
hope u have huge success with all the modifications u plan, great work !!!
Thank you so much. cheers J
As usual excellent production,thanks Josh!
Thank you so much. Cheers J
Great video. Been waiting for this product to be released.
I've fitted quite a few of the genuine version of this. Pleased to see a affordable version lol.
I plumb them into a calorifier and use them to heat multiple radiators too, on narrowboats.
You may want to use a closed loop heat exchanger set up for your hot tub. That way they heater will be run at operating temperature.
Plus once the unit hits 80somthing degrees it will 'back off' to half power. Which has a beneficial effect on fuel and power consumption .
Firstly I'd recommend upgrading the pump to a genuine one as they are completely silent and same goes with the exhaust. The marine silencers are expensive but the best.
Also be careful not to overcool it as they're a bit more sensitive compared to the blow heaters.
Good luck on your mission.
From an un educated tinkerer like yourself. Peace ✌️
@@ijohnathan64 thank you. I've taken notes. Cheers J
Great bit of final advice on student debt
And great video
Thanks
Thank you so much. Cheers J
Every video is gold
Fantastic presentation. New subscriber.. one point, though I don't know how important it is. As the water heat up the heat transfer rate between it and the chamber gets less efficient. I.e. delta T decreases and so does heat transfer. I have no idea how much, but a rise in exhaust temperature proportional to rise in water may give a clue. Anyway, recovering exhaust heat would probably mostly negate this loss.
What a price compared to the Webasto and Eberspacher very nice-looking alloy casts, it appears the Chinese are getting better at quality control. The only thing I noticed was the flow of water is a lot less than my Webasto thermo top. There are specific heat exchangers available when used in a glycol system to heat the air, or indeed hot water for showers or washing. Quite a lot of motorhomes have the same system. Nice to see you warn of the copper pipe's galvanic action also not to be used for exhausts because of poisonous fumes
This was a warming video, much needed here in northern sweden-6°C
I can imagine. Cheers J
Just finished up on a Webasto Thermotop Evo setup. Running underfloor heating. Don’t work as well as hoped requires the unit to run at full speed for nearly an hour to get the whole floor upto temp and unit to idle down. Where using rad’s only takes around 20 minutes to heat the whole system. The amount of diesel used on the UFH is about 4 times the amount of rads. You say you can’t use Cooper & Ali together. My system has been running for 15 years. I’ve not seen and corrosion of Ali parts whatsoever I do use an inhibitor for extra protection. A friend of mine has a wood fired hottub and thinking of doing the same thing. Preheat the water so you can just top it off with wood once you get there
Thank you for putting freedom units on the screen 😂👍
No problem. Cheers J
I understood that the antifreeze added to the water lowers the ability of the fluid to transfer heat. You might want to check that.
Great video Joshua. Keep them coming mate.
Thank you. Cheers J
Awesome video, thank you, Joshua
12:35 Glycol will not get you better efficiency. As a matter of fact, the efficiency will be worse if you use glycol. Usually glycol is mixed with water to stop it from freezing. Even if you don't use pure glycol but a 1:1 mixture with water, the specific heat capacity of the mixture is about 75% of what it would be if you used pure water. This is assuming you're using ethylene glycol.
I knew that, living in Ohio, but I'm sure seone had to hear it😂
I just bought one 3 days ago from Banggood, have no idea what I’m going to use it for but if I have one I will find something to do with it. Shame max run time is 1 hr on the version I ordered but at £200 delivered it’s a no brainer. I hope hcalory come out with a service kit for the unit, seals etc.
Well done. I think it will be possible to fit other controllers. cheers J
I think that heater is awesome! Love the video.
@@RaithUK thank you. Cheers J
looks super cool! Realy handy that it has a build in heat exchanger!
Seems like you could squeeze some more efficientsy out of it by some how capturing the heat produced from the exhaust!
ooops XD i commented this 4 minutes befor the end XD
Definitely. I'll be building a new efficient heat exchanger soon. Cheers J
@@joshuadelisle Those £60 automotive EGR units like you showed in the last vid are great. The exhaust is cool enough to hold your hand in front of! I'm recovering over 400W on the H4 setting on my air heater.
Love the review! Granted this is only a copy of Webasto’s design but it is still very nicely done. The only option I wish it had was a temperature control, in a large storage tank turn on at 5^C and turn off at 10^C, or in a small tank for hot water storage. I’m sure I can figure out how to make it do that with an Arduino.
My thoughts exactly. cheers J
Nice test! I think the efficiency is a bit higher since you are losing quite a bit of energy to the air and workbench ( see the flir image), you would get a more accurate reading if you insulated the container and hoses :)
very true but for a practical output there will always be losses in the whole system so I think the calculation it is still relavent. depending on wether the pipes are insulated or not, it could be far worse. cheers J
Imma give you a thumbs up _just for that thumbnail_
Awesome!
@@EggBastion very kind. Thank you. Cheers J
Perfectly described very clear diction, interesting topics. 5 star
Thank you. cheers J
Loved watching , good one Josh
@@peterwier7920 thank you so much. Cheers J
Yeah, at last a test of one of these ... And top-notch review ... How great ! Any idea of what chinese brands to prefer or avoid ? In terms of air heaters, i have a bad experience with a 5kW Vevor and excellent yet time-limited with 2kW and 5kW FDIK ... The controls and possibly the pumps seem different from one to another ...
@@63n0it thank you. The brand it self isn't important, they're just a name. Knowing who manufactures it is the key because most brands use the same manufacturer. Hcalory has terrible diesel heaters but this water version is fantastic but made by a different factory. Cheers J
@@joshuadelisle Thank you. How do you figure out the factory of an existing and/or of a desired product ? And how to figure out the good factories, then ?
like always Josh, thank you!
Another quality video 💪👌
I like what you said. „ you don’t need always certificate to do things „
Thanks for your hard work 👍 all the best for you and your family
Thank you so much. cheers J
Great video as always but I was hoping for shots of the occupied hot tub 🤩
Looks like a nice bit of kit. Imagine hooking that up with a hot water cylinder. Could quite easily set the unit outside and run some pipes from the water pump.
You certainly could. Cheers J
Why not use 240v inverter? Cheap, and you don't run out when you need it most ( aka sods law) plus, you don't want an abrupt stop, you want the cooldown run...🥂🥂🥂🥂 Great video, as always👍👍👍👍👏👏👏👏
A british pence is about a us penny,and kerosene is hard to find locally since everything has gone to either diesel or natural gas here,but it can be found within 1 hours drive and wouuld be well worth throwing an empty drum in the trucks bed before heading out of town with that for a water heater..
When sealing up things to heat (with in reason) clear silicone works really well against heat, just make sure it has gone off before exposing to heat.
Been using it on car exhaust parts for years.
I realised how good it was after tying to burn some off a piece of glass, it did come off the class. . . or should I say the glass came off it!
Good to know. Cheers J
I commented last time with the idea of a plate heat exchanger, but going directly to water from the source is a much better solution indeed. A lot of heat pump installs use a buffer vessel combination with zone heating. Running the exhaust through the buffer as well would make this pretty efficient, and compatible with "ordinary" heating solutions! Looking forward to your ideas :)!
Excellent. Thank you. Cheers J
LOL love your comment about qualifications. I would love to see how this would work heating a couple of radiators as we live in a 150yr old stone cottage with 0 heating other than a coal fire and 1 radiator. We used to have a hot tub and our electric bill increased nearly £200 per month and that was in 2015, I dread to think what that would be now, but I miss my hot tub lol, this just might be the answer as the max recommended temp for the tub is about 39c. Definitely like to see any more on these heaters. Just found your channel a few days ago, but have seen diesel heaters used in Alaska to heat hen houses etc. Oh and I would escape to Alaska in heart beat. I noticed in a previous video you did a segment on climate change, Totaly agree with your thinking! Thanks for an interesting and educational channel!
regarding accessing the filter gauze I'm not sure but it looked like it was held in by a spring clip which might be accessed by a long nose pliers. Just a thought. Great video thanks.
I've seen others cut the welds and re weld it together. maybe alonf nose pliers might work. cheers J
As always really enjoyed this keep up the good work :)
@@dmbrookfield thank you. Cheers J
