Times have changed. Did a big renovation job like this about 30 years ago in the US, no plastic sheets, no zippers, no respirators, literally threw all the demo materials off the roof or out the windows and cleaned it up later. and coughed like crazy from the dust and crap. You guys are a lot smarter today than we were, cheers to you, something to be said for not breathing in all that stuff.
Hey Scott nice work with the Heatpump, I work in HVAC industry but in Australia, that seems about right in price. Obviously, this depends on amounts of rooms/bedrooms and the number of zones control you have in the system. Heatpump is definitely the future in terms of efficiency, we always remind our consumers it is roughly 3-6 times (300%-600%) more efficient than any other heat source or cooling. without getting all technical, even in cold weather the condenser unit (the outdoor unit) actually absorbs hot air even below 0 degree Celsius temp due to the refrigerant nature and releases hot air into the indoor unit. In Aus we commonly call it 'Air conditioning' but it's the same system.
Heatpumps are the future for most climate zones. If you can move the attic insulation off of the ceiling and into the roof structure, essentially turning your attic into a conditioned space, your heatpump will be even more efficient. Would be a good thing to do when you're replacing the roof. Insulation between the rafters, and rigid insulation boards on top of the roof deck, then add your waterproofing, then airgap (strapping, or mesh product), then metal roof, and you're golden.
Yes its a good thing. However you need to connect the roof to the wall to air seal which is difficult. Its a lot easier if the wall is also sheathed and you can run that sheathing up to the roof sheathing. Also need to install vapor port at the ridge line.
@@cmmartti so whats your air sealing layer? No point insulating and leaking all the warm air out. Hence the use of sheathing is recommended. The weight isn't much. But of couse the issue is how do you tie the walls and gables to the roof so its air tight.
@@AdamLevins1 this is basically just a big minisplit. instead just a wallunit you have a unit in the attic that does the same thing. the absolute peak in efficeincy is when you use a air-water heat pump that heat up underfloor heating. you can almost double the efficiency with that system.
It's great! My shed has been completed and it turned out nice looking and sturdy and it is way better than the sheds that many of my neighbors had put up. Of course, I'm pleased with the outcome and this Ryan's ruclips.net/user/postUgkxGZedDTcDfgD7fG_uU4esfx_EgxzlY2_1 Plans was extremely useful to me as a guide.
About getting rid of the fireplace: Many households in Germany bought fireplaces in the last year, because cost for other means of heating (oil, electricity & especially gas) has gone way up about more than 400% in some instances. So that's why some people might be shocked about the removal
I paid about the same as that this year in Australia but that price included a MyPlace controller with individual room temperature control for 7 rooms. With the controller you don't need to heat (or cool) the entire house, you only heat the rooms you want. Great videos, keep them coming!
That's very cheap, I got multiple quotes in Vic for room controlled heat pump system in a 150m2 4 bedroom house and cheapest was 22k most expensive was 33k but the average was 26k
Man you got a good deal. We looked into an option that would be similar to controlling each room temp. It would of been done using dampers, estimated at $350 extra per room. We decided it wasn’t needed for our (relatively small) house. We use the whole house everyday anyway, but it’s a great idea if you don’t.
Rosie, any chance you could share the name of the company you went with? Also a big thanks to Scott for the incredible content and creating these discussion
I'm liking what ur doing Scott. My wife and I went a different way. Heating wise, 1960s house fully insulated top, bottom and walls and new double glazed windows, Installed a single heat pump and kept the fireplace too. My wife likes the heat from the fireplace as do I. The heatpump is mainly to cool the house in summer as it rarely came on this winter seeing as the fireplace did a great job. House is ventilated via smartvent as well so that transfers heat throughout. It's a warm efficient house.
In Northern New England USA most people have a wood stove. In my house we use wood as our primary heat, but do have air source heat pumps as a secondary source. Our power supply is often interupted during winter storms, so having the wood heat is a good idea. You are right in terms of efficiciency heat pumps are the most efficient, only using electricity to transfer heat, not creating heat. Love the videos as allways. Keep up the good work. I will say I miss your Aukland co-workers!
I paid AUD$22K for a heat pump system recently (5bed house) to replace a (dead) ducted gas heater and evap cooler - just got our first quarterly electricity and gas bill - I actually came out $100 ahead! Given that gas prices are going up, and I have solar - it seemed like the right thing to do. Also double glazed the south side of the house (saving up to do the rest) - all in all well worth it - this winter has been a lot more comfortable.
$7,500 NZD 8kw ducted heat pump (4 room) in 2019 in AKL. 2 story house and that heats and cools the upstairs very well. Two split units downstairs covers the lounges. Great hint for kiwi's, we use Electric Kiwi power company that gives one hour if iffpeak power a day for free. We choose 6am to 7am and have all the heat pumps come on then, wake up to a nice and toasty house for free, and basically hardly ever need to trun the heat on in the evenings, only the real cold nights.
Revisiting the root cause is the lax building codes in Aus/NZ previously. Consequently we freezing in winter and horribly hot houses in summer. So glad we are giving insulation the attention it deserves. Less heating and cooling costs
Glad it was you taking that chimney down and not me! I've had to break out concrete before and it was a LOT of hard work! Looking good now though. Will be good to see the finished results.
I DIY’d an 18kbtu (ducted) mini split for under $3000 USD. Saved a lot, and learned a lot. One third the costs went toward ductwork. Works well to cool half a 1600 square foot house. But the old gas furnace was still more cost effective for heating. These mini split units use r410A - which is being phased out. Lately it has become as expensive as freon to recharge. I’m hoping for a brighter future where solar panels store energy in a new type of battery that filters CO2 as a byproduct of discharging. Then that CO2 gets used (when not for bubbly beverages) to top off an HVAC that uses CO2 as a coolant, instead of explosive gasses. How useful could that be if everyone sequestered CO2 in their home, saving it as a resource.
That's actually a pretty decent price for a whole house unit. Heat pumps are for sure the future of home heating and cooling IMHO. Your house will look amazing when done
I live in southern, Southern California. Central HVAC is standard and essential for us. We added Solar and now have reduced the electric bill to less than $100 per month during the hottest months. The roof panels also shade the house. The panels payed for themselves in under two years.
My wife walked in just as you were eating those amazing looking toasties and asked me what we should do for dinner. I just pointed at the screen. looks like it's toasties for dinner :P
We run a inverters as well and we run the all year round. Temp set to 21°C and auto. Keeps us warm and dry all year. The only time our systems are turned off is when we do our full house clean every 2 months or so. It is less hassle than burning wood.
Great use of a heat pump - the key is that you put 1Kw of electricity into the system and it delivers you 3Kw of heating (whereas just heating a 1Kw electric fire would just deliver you 1Kw.) Using the 'heat' (temp difference) you are extracting/capturing that heat in a very efficient way to heat the house and getting a 3 for 1! To reduce costs further decide if you are happy with 18 degrees (minimum 'recommended') and everything you are doing (insulation, glazing etc) is only going to make this better as your heat-up time will be faster, and heat loss way less. Modern, responsible home ownership! Love your videos (I'm a UK architect.)
Helped a mate take out a 2 storey chimney years ago, we built a frame at the base and used chain blocks with steel bar through the block to hold it then broke it up from the bottom a meter at a time then lowered it down and repeated the process.
Cut through the mortar joints with a TCT recip saw blade like the Bosch S1543HM, (excellent for toothing out brickwork). Way less dust than the disc cutter!
Hey mate good watch. I think its not a bad price for the heat pump, but saying that I spent around 50k nzd on a heating system. Im a kiwi in Sweden. We converted from electric radiators to what they call Rock heating (bore in the ground down 150+m, to a heat pump then to water radiators) But also has cut the cost of heating our house by around 60% ( also heats our hot water). We get down to -25 in winter. Keep the videos coming they are great.
Removing that chimney was very safe and methodical. The only thing you may consider next time is using throw-away paper overalls with a hood then that dust doesn't get in your hair or your ears. Well done...
I just got an air-to-water heat pump. Had a gas heater before, and like this setup much better. Cost around €20,000 which is also just under 2% of the house price. I live in Denmark
Highly recommend a ducted heatpump. I’m surprised at your power bill though jumping by 100$. My wife and I are based in Dunedin, got a rianni ducted heatpump installed and we saw a jump of about $20 from using our existing single room heatpump. About 12k to buy and install (removed broken fireplace as well). Winter power bill is about 230$ summer is around 100$ (off during the day). We have a 3 bedroom, insulated walls but single glazing (getting there). Make sure fan is on auto, then the system controls the consistent temperature. Love the videos, keep them up!
@@aussiegruber86 - run it at 21c / during winter we turn it up to 22c at night. Summer it’s not generally on unless we have a cold night of like 10 degrees then it sits on 20c overnight.
Hi Scott, love your videos. I don't know if you watch the Essential Craftsman but he always says to keep up the good work. You are doing an awesome job with the remodel of your house. Keep up the good work!
I going to tear out my chimney and fireplace in the coming months. I've done a couple in the past, I felt your pain during that horrible job. Excellent plan you have! I'm putting in 2 mini-split heat pumps instead of my gas wall heater.
Yes, something we want to look into eventually. We still have our hot water run by gas so we want to change that too. We get great all-day sun on our roof.
@@ScottBrownCarpentry Hi Scott I have gas hot water what will need replacing soom why may I ask would you go away from gas? I am not a strong beleiver in solar in NZ we get no government subsidy and isn't worth connecting to grid so big battery bank would be only option. By the time it's paid for its self its time to start replacing
You will love the heat pump. I'm in US mid/south-east, so a bit different, but I think similar in a way, because we still get cold winters with super hot summers. Heat pump we got two years ago is 3 tonnes (my house is a bit bigger than yours and has garage embedded, so needs a big unit, but comparing to old oil unit, it is way more efficient. It moves air likes crazy and in combination with solar, it is pretty much a no-brainer.
Congrats on going full circle on your videos (#360). Always enjoy the info, the personality, laid back feel and the music. It's lunchtime as I write this and wow but I'd love one of Jess' toastie sandwiches' right now too.
Scott… amazing as always. I wouldn’t worry about not having a chimney, new builds in the UK haven’t had chimneys for about 20yrs. We just have radiators (wet central heating). If people want fires they then have to fit external twin walled flue. Great vid. Love the fan to move dust.
We have the exact ducted system by Mitsubishi and also a Lossnay unit (part of Mitsubishi) which circulates the fresh air and stale air into the ducted system. Helps circulate fresh air from the outside and is a cheap way of cooling the house in the warmer months without switching to cooling mode. House no longer smells stale either. Look into it Scott!
I replaced my gas heaters (vented , non vented) with hot water radiator central heating system. 9 radiators and a gas combi boiler to provide continuous hot water and heating. Each radiator has its own thermostat and central smart programmable timer. Heats the house in no time and silent, no draughts and still works 100% when room doors are closed. Ducted systems need air returns to get circulation. Total cost was the same as your system. 1960's brick house, roof and underfloor insulation. Did have a polythene moisture barrier installed on the ground under the house about 10 years ago. was sooo cheap to have done. Stopping the damp rising from the ground to/through the floor made a huge difference. Much easier to heat a dry house than a damp one, regardless of the heat source. Only problem is that the native timber floor boards have shrunk and some creaks have resulted. As I don't have bare floors, its not a problem.
We split ours to be more effective with smaller units. So have 2 HVAC systems in the ceiling. One purely for the rooms and the other for the living/dining areas. Paid 7k per unit. Works out the same. But the overall running costs are less. Adds about 40 per month over winter.
Scott, I paid more for my ductless heat pump system. One main unit with two indoor heads, about $10K USD. Still worth it for combined heating and cooling, and I live way up in NW US (Washington State) where it almost always never gets too cold or too hot.
Heat pump is by design as efficient as it can get. Technology Connections has a fantastic video or videos explaining how and why every house with very minimal exceptions should be heat pump.
I have a chimney to take apart some day, but we've got 3 stories, so I have no idea how (or if that plan will fly) I'm going to do that from the basement up (prioritizing living space needs). I would certainly do it in a similar fashion, though! Our heat pump set up is 5 mini-split units and 2 exterior units. Installed by the previous owner in 2018/19, cost about $30,000 CDN. Roughly 7% of the home's value at the time. And she did all the windows, too. Pretty sweet deal we got, mostly.
I used the zip wall system when I was renovating my kitchen. Mounted A fan near the window. Did all my demo one section at a time. Parked my truck outside and loaded each section. Did three sections. Vacummed each section and mopped. There stood three bare walls. Attacked each section. Electrical next. Mounted new switch boxes. Next each section. I put up new drywall called green board for mold resistant. Cut my windows out with a zip saw for drywall. Vacuumed each section as I went. Next was the plastering. Taped and plastered each section. I had a corner wall by our fridge. I repaired it too. Then came the paint. Wife chose the color. Wiped walls down and started painting. 2 days later. I received my upper wall kitchen cabinets. I finally took my zip wall system down. Put up my ledger board for wall cabinets. Mounted my new kitchen hood. Mounted my 3 wall cabinets and removed my ledger. Next was to finish my outlets for my lights and switches and GFCI. Do to some errors on delivery off my lower cabinets. I had to wait 3.5 weeks. But that gave me time to finish or touch up remained work. Bottom cabinets finally arrived. Drove to the store. Got my orders loaded up. 4th week. I finally started installing lower cabinets. During the week while we were waiting for cabinets to arrive. Our fridge and stove failed. Luckily we found a set and got them installed. Lower cabinets finally installed. Next counter tops? After a few days of decisions by my wife. She settled on tile counter tops. Bought all of the materials I needed. 2 weeks of final work including working my regular schedule. I was done. I've never attempted to do anything of this level before. Lots of planning and work by myself. I finished. I am 68 yrs old and I'm feeling good. I still need to finish some plumbing.. My son lives 1.5 hours away. Plus he has a job too. But he did stop by to help wire my new shed. ❤
I am 100% for having wood burners, but in saying that I have endless amounts of firewood trees on my property so it only takes a bit of grunt work...which is free...Plus I really enjoy cutting wood.
It seems a few people in the comments think you should have kept your fireplace. The point those people are missing is that you are not allowed to have an old fireplace in Nelson because of the air pollution. I loved what you said about people saying, "You're crazy to get rid of your fireplace. If the world goes upside down and there's no electricity, you won't have any heating!" Welcome to Nelson, Scott. Lotsa people here think the end of the world is coming.
he also wont have hot water as its a continuous flow it needs electricity to spark and stay running for temperature control. Also log fires aren't great for your health the smoke particles hang around for up to 3 days and increase your chance of smoke related cancer alot. so i fully support his decision to remove it.
The Green commies have taken over the asylum. All are heavily invested in the "climate change" scam. I'll die before I let anyone take my wood stove away from me. Mental is the key part of environmentalist. Stay strong, masculine and free. No to the convid and climate change scams, 🔨🌲🇮🇪🇮🇪
Since you're on the south island power is abundant. But you could complement with solar but that again is expensive. We have gas ducted and it is in the same range monthly cost. Wonderful heat though. I am contemplating to add a small heat pump to utilize the power from our solar. Especially for cooling in summer.
Sounds like a great deal compared to cost where I am. I went with gas heat / outdoor compressor for cooling only. I like the warmer air from the gas, and part of the year it is too cold for a heat pump to operate efficiently. Here, gas is also cheaper than electricity.
Our single heat pump installed in our lounge was $3500 NZD. Our woodsman fireplace was $4800 NZD and another $700 for a through wall heat transfer that blows the heat down the hallway. So $9k for hearing the lounge area. The rest of the house is hated indirectly by radiance. $13k to have every room indirectly heated isn’t bad. A friend has a modern new build with ducted heat pump and their power consumption over winter was only $35 a month as once the house is up to temp it takes very little to maintain it at that level.
Hi Scotty & Jess we have gas heaters in our home its piped along the road. Nice and clean no mess. We spent $11,000 on the two heaters floor and roof insulated. Being an old house 1922 build its not insulated in the walls. We can have that done for around $7000 but no double glazing. Thanks for a great episode love your work always.
Kind of happy and sorry at the same time to see an older fella still on the tools. Not a fan of air source heat pumps. But I'm in Croatia, where it can be -10 c in winter. Had to work in a house with it during winter, never felt warm.
I spent about $6500 AUD for my 14kw heat pump about 4 yrs ago. Plus another thousand or so for ducting, vents grills ect, and installed it all myself. Just had the fridgey do the gas lines. Seen it done plenty enough times on site to give it a shot. They are the most efficient option, just a matter of keeping the heat in my 1960's fibro shack 🙄. Improving it bit by bit.
13 & 1/2 G bangers sounds pretty good for ducted heat pump system. Having a house that is all warm (and always warm) is somewhat of a novelty in NZ - crazy huh!!! I agree with your thought that if power is no longer available for your heat source then sh!t has got pretty real and you will have bigger problems. For us (at Lyford) we can’t rely on power as we have too many power cuts (especially in winter) - often for a day or more. We rely heavily on our log fire (helps we have 3 Ha of bush from which we can extract free firewood). We are looking at building here and hope to have a heat recovery system in a passive house and a smallish log fire. It is the most efficient way for new builds (not realistic for old houses with poor thermals). Capital cost is about the same as ducted heat pump, but would operate 100% off grid.
Oh and smart move putting washing machine on concrete - I was all busy posting a comment to you to make sure you did put washing machine on concrete when you said that’s what you are doing.
Ducted is less invasive, but high wall units connected to single or multi-split compressors is more efficient. I have 7 highwall units on 4 compressors and only need to heat/cool the rooms I need, plus the minimum power draw is less on smaller units. Last month power was $235 and several units are on 24*7 - in Auckland.
G,day Scott and Jess from Sydney Australia. I think you missed some ceiling insulation, every bit helps reduce heat loss. I do like the new heat pump system all the same. 🌏🦉
Radiant floor heating is pretty efficient way. But makes more sense when building a new house. As in renovation one would need to take up all the floors. I have 12kW in my house but I'm not restricted with lot size like Scott because in my case I needed about 900m (close to 1000m2 space) of piping in ground for the heatpump. Machine itself costs about 9K another 5K goes for the accessories. 3,5K for laying down the ground piping. But then one would need in house radiant floors.
We’ve got a similar sized house to yours Scott, the cost for us is about $60/month. We’re fully insulated and double glazed. I remember being in London paying £200 a month on gas! Heat pumps are great and you’ll get air conditioning in the summer! 😊
Hi Scott, love all your videos. I did a similar job on my first home. Me, this Kiwi DIYer who doesn't do things by the book, it's nice to know now how it should have been done haha. I removed my fireplace from the bottom...😅
I would definitely go with a heap pump as well. But use a ground-to-water type instead and use in-floor heating (Hydronic). Both the things increase efficiency a little and are just nicer to live with. That seems to be a really good price. Here in Scandinavia they are in such high demand that they cost double. Due to a lack of qualified installers and the component shortage
@@steventhomas9461 Nope. No radiators. Just tubes in the floor. It's much nicer to walk on. You can have a lower room temp but still feel warm and the in floor heating requires a much lower water temp because of the large surface area. Meaning your heatpump doesn't have to heat the water up to as high a temperature. This raises your COP factor massively
For example. A Panasonic AQUAREA. Looking at the datasheet. When going from 55C to 35C water in the house heating system. The COP factor goes from 3,07 to 4,85. That is a massive difference.
We did a retrofit in my sisters house. Same thing as Scotts house. Wooden floors and a crawlspace. Was hard work, but it really paid off. Could remove the radiators and got a ton of insulation in there afterwards
3years ago it was 10k for a ducted system for my home here in Southland, but regrettably went for 2x heatpumps and a heat transfer to utilize exess heat from the fire. Looking back the ducted system would of been worth it 👌
Love watching your videos. Would recommend next time to use a disposable suit so you don't put all the cement dust through the washing machine when you wash your overalls/clothes
Question for you Scott? Can you say how much you would of charge for dismanteling the chimney if you were doing it for a client? Like how many hours, cost for the garbage bin, fan rantal and pipes etc etc. Thanks in advance.
Like this one that is combination of reinforced sections and cast? 2 days 2 guys work plus equipment and removal. Not including any remedial wall and roof construction. Should be around $3K
This is all awesome content but in watching other videos about windows efficiencies and stuff, any window no matter the rating equates to having, basically, a hole in your wall. Double glazing, triple, glazing, blah blah. It doesn’t matter cuz they won’t work after ten years. Brent Hull has a wonderful video on 100 year windows you must watch. All that said, will you be adding an interconnect for a dual fuel power generator for those days without power now that you don’t have a chimney? After the hard freeze here in Houston I got a genny and made it run on natural gas and it runs the whole house. 10000 watts. Keep the content coming. Love the show. Smoko time for me now. 😂
I paid $12,600 in 2020 for the same system in Taupo. So with inflation your 13.5k is right on point. Also look into solar, it pairs quite nicely with a heat pump. Getting one put in next month. We should half our power bill with an 8kw system on a north facing roof. Pays back in 9 years. Some of the banks are doing good low or no interest loans for this stuff now.
We installed an air/water heat pump a few month ago in Sweden, it cost about 21k NZD which is about 2% of the house cost of a house where I live in Sweden. Compared to heating with gas it should save about us about 30-50% on the heating cost. Around 6 years ROI.
Geological Thermopumps is popular here in Sweden. Since they are far more efficient in keeping the house warm cheap. But it does require a house ,as you say, well insulated.
I have regular power cuts in England. Without a fire I wouldn't have been able to heat the house or cook food for three months during autumn and into winter last year.
Zip wall is a great product, is s what I use for dust protection here in the states. It is unnecessarily expensive for mostly plastic. It is great and very easy to set up though. You can put up a whole dust wall up to 12 feet high by yourself in a matter of minutes. Its legit. Glad that you can get it way over and way down there. Like dyown undah? Just kidding, I know you kiwis don't necessarily like to be confused for Australians.
$7800 US is pretty good. I just had one installed in our house and it was $13000 US. It’s a retro fit and a big house. I think it’s a 3 ton unit. Worth every penny.
I paid $13K for a Mitsubishi HVAC system so my heat and AC come from outside the house through their inverter heat pump. Our house is 3600 square feet so we needed their hyper heat system. The company I retired from used these for their clean rooms and never had a failure. From what I understand it will provide up to 100 percent of heating capacity at 5° F and continue operation down to -15° F even without auxiliary heat. The first year we had it we got hit with days over 100F and the winter got us below zero. It just kept on going. The unit inside the garage is the fan and control system. We were previously on gas heat and heating in my state is usually hydroelectric and gas. There are some homes that are heated by wood. When we switched we noticed our bills drop down, even with AC on the really hot days.
I was dead keen for that Lossnay system but the quoted price around the same as what you paid put me off. I went with a 8kw heating AP71 heatpump in a central location for $5k with the outside unit out the back of the house. It’s over spec’d for the room but it has brought up the temp up in the whole house. The house is a fully insulated 1940s weatherboard. Power bill has only gone up $25 a month. A good compromise in the end.
in the UK, air source heat pumps are typically around the same price for a small domestic unit, which is probably the size you'd need for a house the size of yours 😊
So, on your last video I commented on how effective a shop vac can be at capturing dust. That, um, doesn't really apply here LOL. Very well done on the tent & fan.
With all the insulation you’re adding you might consider optimising your heat/cool schedule to minimise your power bill. It’s an idea taken from tech connections but essentially it’s using off peak electricity pricing plus your homes air as a thermal battery to minimise heating and cooling. In summer you overcool (minimum comfortable temp) the home just before offpeak pricing ends and then set it to your max comfortable temp immediately after. The home should maintain a comfortable temperature for a long time before needing to kick the AC back on. In winter you do the opposite. If you have solar you can also set a midday “recharge”.
Hey Scott, 2 inch air gap under roof sheathing so intake soffit air can flow to ridge vent to keep roof from over heating and adding stryofoam as insulation, I used 6 inches of the blue colour, 2inches per sheet x's 3 sheets . It turned out to be a cathedral ceiling of the porch and the difference in comfort is amazing. You want your HVAC system to not be in an overheated air space so it will not take that heat surrounding it and heating the air conditioned air that you want in the Summer months. It is a common error to put an HVAC in a very hot attic. Not a smart Idea. Insulate the roof underside of your attic to make it a comfortable living space and your HVAC will not have to work as hard and you will also see that your energy bill will be reduced. I look forward to an episode where you will show how to insulate the roof sheathing with that 2 inch air space. Trust me, I have done it and it is AMAZINGLY comfortable in the heat of our Summers here in Atlantic Canada. Keep up the good work to you both from East Canada.
Those small dust extractors are really only good if they’re right next to where you’re working. For big rooms you need to get 2-3 big ones, pump air in with 2 and extract with 1 so you’re basically forcing the dust out
Yes I would pay that much, would love more info on where you got it. I'm in the Bay of Plenty and when I looked online I only found them in the 20-30 thousand price range. I also removed my fireplace because the price of firewood is ridiculous.
Rather than using electricity to make heat through a resistor, like a oven or fan heater or oil column heater etc, the AC is using electricity to compress the refrigerant, which then wants to steal heat energy out of the environment. It can steal more heat energy than the electricity could provide, all we need to use electricity for it moving it around which is a lot easier than trying to heat it directly. Its basically allowing a chemical reaction happen, but controlling where it happens. The RUclips channel Technology Connections has a whole bunch of videos explaining this topic in depth, since it also is the same process by which fridges and freezers works. But long story short, you are using electricity to control something that can move heat better than the electricity can, hence you get values of 400% efficiency or better (1 watt in, 4 watts out). Also like how a fuel tanker can move more fuel than the engine uses, to facilitate more power in a remote town than the truck engine produces.
We have air to water heat pump with underfloor heating downstairs. Havent had a winter with it yet but looking good so far. I think its around €7000 to install but there are grants of 3000 to assist if upgrading
Times have changed. Did a big renovation job like this about 30 years ago in the US, no plastic sheets, no zippers, no respirators, literally threw all the demo materials off the roof or out the windows and cleaned it up later. and coughed like crazy from the dust and crap. You guys are a lot smarter today than we were, cheers to you, something to be said for not breathing in all that stuff.
Hey Scott nice work with the Heatpump, I work in HVAC industry but in Australia, that seems about right in price. Obviously, this depends on amounts of rooms/bedrooms and the number of zones control you have in the system. Heatpump is definitely the future in terms of efficiency, we always remind our consumers it is roughly 3-6 times (300%-600%) more efficient than any other heat source or cooling. without getting all technical, even in cold weather the condenser unit (the outdoor unit) actually absorbs hot air even below 0 degree Celsius temp due to the refrigerant nature and releases hot air into the indoor unit. In Aus we commonly call it 'Air conditioning' but it's the same system.
Heatpumps are the future for most climate zones. If you can move the attic insulation off of the ceiling and into the roof structure, essentially turning your attic into a conditioned space, your heatpump will be even more efficient. Would be a good thing to do when you're replacing the roof. Insulation between the rafters, and rigid insulation boards on top of the roof deck, then add your waterproofing, then airgap (strapping, or mesh product), then metal roof, and you're golden.
Yes its a good thing. However you need to connect the roof to the wall to air seal which is difficult. Its a lot easier if the wall is also sheathed and you can run that sheathing up to the roof sheathing. Also need to install vapor port at the ridge line.
This isn’t a North American house. Building science is a bit different. The climate is also more mild so the gains wouldn’t justify the expense
@@cmmartti so whats your air sealing layer? No point insulating and leaking all the warm air out. Hence the use of sheathing is recommended. The weight isn't much. But of couse the issue is how do you tie the walls and gables to the roof so its air tight.
What about mini splits? Are they no more efficient?
@@AdamLevins1 this is basically just a big minisplit. instead just a wallunit you have a unit in the attic that does the same thing. the absolute peak in efficeincy is when you use a air-water heat pump that heat up underfloor heating. you can almost double the efficiency with that system.
It's great! My shed has been completed and it turned out nice looking and sturdy and it is way better than the sheds that many of my neighbors had put up. Of course, I'm pleased with the outcome and this Ryan's ruclips.net/user/postUgkxGZedDTcDfgD7fG_uU4esfx_EgxzlY2_1 Plans was extremely useful to me as a guide.
You did good. And great job mitigating the silica dust hazard. right on, Scott.
About getting rid of the fireplace: Many households in Germany bought fireplaces in the last year, because cost for other means of heating (oil, electricity & especially gas) has gone way up about more than 400% in some instances. So that's why some people might be shocked about the removal
I'm renovating as well, in rainy Belgium. We also put a heat pump, heavily isolated the house, but it's floor heating.
What a very clever idea with the sprinkler for dust control.
I paid about the same as that this year in Australia but that price included a MyPlace controller with individual room temperature control for 7 rooms. With the controller you don't need to heat (or cool) the entire house, you only heat the rooms you want. Great videos, keep them coming!
That's very cheap, I got multiple quotes in Vic for room controlled heat pump system in a 150m2 4 bedroom house and cheapest was 22k most expensive was 33k but the average was 26k
Man you got a good deal. We looked into an option that would be similar to controlling each room temp. It would of been done using dampers, estimated at $350 extra per room. We decided it wasn’t needed for our (relatively small) house. We use the whole house everyday anyway, but it’s a great idea if you don’t.
damn that is a really good deal, 7 zones for that price.
Rosie, any chance you could share the name of the company you went with?
Also a big thanks to Scott for the incredible content and creating these discussion
@@ScottBrownCarpentry yes same here, considered dampers but concluded it’s not necessary unless it’s a big house (200m2+) with say multifloors
I'm liking what ur doing Scott. My wife and I went a different way. Heating wise, 1960s house fully insulated top, bottom and walls and new double glazed windows, Installed a single heat pump and kept the fireplace too. My wife likes the heat from the fireplace as do I. The heatpump is mainly to cool the house in summer as it rarely came on this winter seeing as the fireplace did a great job. House is ventilated via smartvent as well so that transfers heat throughout. It's a warm efficient house.
You did it the Correct way.
Hi Scott, we paid almost the identical price to do ours in Australia, After getting four quotes we call it a fair price plus the system works a treat
In Northern New England USA most people have a wood stove. In my house we use wood as our primary heat, but do have air source heat pumps as a secondary source. Our power supply is often interupted during winter storms, so having the wood heat is a good idea. You are right in terms of efficiciency heat pumps are the most efficient, only using electricity to transfer heat, not creating heat. Love the videos as allways. Keep up the good work. I will say I miss your Aukland co-workers!
I paid AUD$22K for a heat pump system recently (5bed house) to replace a (dead) ducted gas heater and evap cooler - just got our first quarterly electricity and gas bill - I actually came out $100 ahead! Given that gas prices are going up, and I have solar - it seemed like the right thing to do. Also double glazed the south side of the house (saving up to do the rest) - all in all well worth it - this winter has been a lot more comfortable.
$7,500 NZD 8kw ducted heat pump (4 room) in 2019 in AKL. 2 story house and that heats and cools the upstairs very well. Two split units downstairs covers the lounges. Great hint for kiwi's, we use Electric Kiwi power company that gives one hour if iffpeak power a day for free. We choose 6am to 7am and have all the heat pumps come on then, wake up to a nice and toasty house for free, and basically hardly ever need to trun the heat on in the evenings, only the real cold nights.
Your a true professional Scott. Not many out there like you
Revisiting the root cause is the lax building codes in Aus/NZ previously. Consequently we freezing in winter and horribly hot houses in summer. So glad we are giving insulation the attention it deserves. Less heating and cooling costs
Glad to hear youre back on the tools next year, albeit am enjoying the reno.
Scott those fans are the best, for my renovation it was a lifesaver and in the next few projects, its paid for itself already!!!!
Glad it was you taking that chimney down and not me! I've had to break out concrete before and it was a LOT of hard work!
Looking good now though. Will be good to see the finished results.
I DIY’d an 18kbtu (ducted) mini split for under $3000 USD. Saved a lot, and learned a lot. One third the costs went toward ductwork. Works well to cool half a 1600 square foot house. But the old gas furnace was still more cost effective for heating. These mini split units use r410A - which is being phased out. Lately it has become as expensive as freon to recharge. I’m hoping for a brighter future where solar panels store energy in a new type of battery that filters CO2 as a byproduct of discharging. Then that CO2 gets used (when not for bubbly beverages) to top off an HVAC that uses CO2 as a coolant, instead of explosive gasses. How useful could that be if everyone sequestered CO2 in their home, saving it as a resource.
That's actually a pretty decent price for a whole house unit. Heat pumps are for sure the future of home heating and cooling IMHO. Your house will look amazing when done
Great video SBC.. such appropriate music..Your set up was amazing . The music finished it off!!👍😎great work.
I live in southern, Southern California. Central HVAC is standard and essential for us. We added Solar and now have reduced the electric bill to less than $100 per month during the hottest months. The roof panels also shade the house. The panels payed for themselves in under two years.
Please continue with the classical music in the videos! Really nice to watch to!
My wife walked in just as you were eating those amazing looking toasties and asked me what we should do for dinner. I just pointed at the screen. looks like it's toasties for dinner :P
That’s a great chunk of concrete removed Scott,coming on nicely with this project. Thanks for the latest exciting episode.👍👍
We run a inverters as well and we run the all year round. Temp set to 21°C and auto. Keeps us warm and dry all year. The only time our systems are turned off is when we do our full house clean every 2 months or so. It is less hassle than burning wood.
Great use of a heat pump - the key is that you put 1Kw of electricity into the system and it delivers you 3Kw of heating (whereas just heating a 1Kw electric fire would just deliver you 1Kw.) Using the 'heat' (temp difference) you are extracting/capturing that heat in a very efficient way to heat the house and getting a 3 for 1!
To reduce costs further decide if you are happy with 18 degrees (minimum 'recommended') and everything you are doing (insulation, glazing etc) is only going to make this better as your heat-up time will be faster, and heat loss way less.
Modern, responsible home ownership!
Love your videos (I'm a UK architect.)
Modern inverter HPs are running efficiencies of more like 5:1
Helped a mate take out a 2 storey chimney years ago, we built a frame at the base and used chain blocks with steel bar through the block to hold it then broke it up from the bottom a meter at a time then lowered it down and repeated the process.
Cut through the mortar joints with a TCT recip saw blade like the Bosch S1543HM, (excellent for toothing out brickwork). Way less dust than the disc cutter!
@@cmmartti have cut through EML with one but it can damage the teeth. Can easily change the blade for a metal one if you know you’re up to the rebar.
Hey mate good watch. I think its not a bad price for the heat pump, but saying that I spent around 50k nzd on a heating system. Im a kiwi in Sweden. We converted from electric radiators to what they call Rock heating (bore in the ground down 150+m, to a heat pump then to water radiators) But also has cut the cost of heating our house by around 60% ( also heats our hot water). We get down to -25 in winter. Keep the videos coming they are great.
Removing that chimney was very safe and methodical. The only thing you may consider next time is using throw-away paper overalls with a hood then that dust doesn't get in your hair or your ears. Well done...
I just got an air-to-water heat pump. Had a gas heater before, and like this setup much better. Cost around €20,000 which is also just under 2% of the house price. I live in Denmark
@andrew carey I can
Highly recommend a ducted heatpump. I’m surprised at your power bill though jumping by 100$. My wife and I are based in Dunedin, got a rianni ducted heatpump installed and we saw a jump of about $20 from using our existing single room heatpump.
About 12k to buy and install (removed broken fireplace as well).
Winter power bill is about 230$ summer is around 100$ (off during the day).
We have a 3 bedroom, insulated walls but single glazing (getting there).
Make sure fan is on auto, then the system controls the consistent temperature.
Love the videos, keep them up!
How many hours a day do you run it and what's the temperature set to
@@aussiegruber86 - run it at 21c / during winter we turn it up to 22c at night.
Summer it’s not generally on unless we have a cold night of like 10 degrees then it sits on 20c overnight.
Awesome mahi from u an the young fala smashed it out very fast an also get the added bonus of not hearing your washing machine👌
Hi Scott, love your videos. I don't know if you watch the Essential Craftsman but he always says to keep up the good work. You are doing an awesome job with the remodel of your house. Keep up the good work!
I going to tear out my chimney and fireplace in the coming months. I've done a couple in the past, I felt your pain during that horrible job. Excellent plan you have! I'm putting in 2 mini-split heat pumps instead of my gas wall heater.
Hi Scott! Your house is becoming so beautiful! Talking of power, have you thought about solar panels on the roof to power your house?
Solar would make a lot of sense, considering they’re literally in the sunniest part of the country
+1
Probably part of the reason for removing the chimney (to prevent shadowing)
Yes, something we want to look into eventually. We still have our hot water run by gas so we want to change that too. We get great all-day sun on our roof.
@@ScottBrownCarpentry Hi Scott I have gas hot water what will need replacing soom why may I ask would you go away from gas? I am not a strong beleiver in solar in NZ we get no government subsidy and isn't worth connecting to grid so big battery bank would be only option. By the time it's paid for its self its time to start replacing
You will love the heat pump. I'm in US mid/south-east, so a bit different, but I think similar in a way, because we still get cold winters with super hot summers. Heat pump we got two years ago is 3 tonnes (my house is a bit bigger than yours and has garage embedded, so needs a big unit, but comparing to old oil unit, it is way more efficient. It moves air likes crazy and in combination with solar, it is pretty much a no-brainer.
Congrats on going full circle on your videos (#360). Always enjoy the info, the personality, laid back feel and the music. It's lunchtime as I write this and wow but I'd love one of Jess' toastie sandwiches' right now too.
Following that logic, I've been watching since the first quadrant.
Scott… amazing as always. I wouldn’t worry about not having a chimney, new builds in the UK haven’t had chimneys for about 20yrs. We just have radiators (wet central heating). If people want fires they then have to fit external twin walled flue. Great vid. Love the fan to move dust.
Can't beat a real fire though.
OMG that was the most amazing demolition music ever. Ever ever. 😊😊😊😊😊😊😊
We have the exact ducted system by Mitsubishi and also a Lossnay unit (part of Mitsubishi) which circulates the fresh air and stale air into the ducted system. Helps circulate fresh air from the outside and is a cheap way of cooling the house in the warmer months without switching to cooling mode. House no longer smells stale either. Look into it Scott!
I replaced my gas heaters (vented , non vented) with hot water radiator central heating system. 9 radiators and a gas combi boiler to provide continuous hot water and heating. Each radiator has its own thermostat and central smart programmable timer. Heats the house in no time and silent, no draughts and still works 100% when room doors are closed. Ducted systems need air returns to get circulation. Total cost was the same as your system.
1960's brick house, roof and underfloor insulation.
Did have a polythene moisture barrier installed on the ground under the house about 10 years ago. was sooo cheap to have done. Stopping the damp rising from the ground to/through the floor made a huge difference. Much easier to heat a dry house than a damp one, regardless of the heat source. Only problem is that the native timber floor boards have shrunk and some creaks have resulted. As I don't have bare floors, its not a problem.
We split ours to be more effective with smaller units. So have 2 HVAC systems in the ceiling. One purely for the rooms and the other for the living/dining areas. Paid 7k per unit. Works out the same. But the overall running costs are less. Adds about 40 per month over winter.
Scott, I paid more for my ductless heat pump system. One main unit with two indoor heads, about $10K USD. Still worth it for combined heating and cooling, and I live way up in NW US (Washington State) where it almost always never gets too cold or too hot.
Heat pump is by design as efficient as it can get. Technology Connections has a fantastic video or videos explaining how and why every house with very minimal exceptions should be heat pump.
I have a chimney to take apart some day, but we've got 3 stories, so I have no idea how (or if that plan will fly) I'm going to do that from the basement up (prioritizing living space needs). I would certainly do it in a similar fashion, though!
Our heat pump set up is 5 mini-split units and 2 exterior units. Installed by the previous owner in 2018/19, cost about $30,000 CDN. Roughly 7% of the home's value at the time. And she did all the windows, too. Pretty sweet deal we got, mostly.
I used the zip wall system when I was renovating my kitchen. Mounted A fan near the window. Did all my demo one section at a time. Parked my truck outside and loaded each section. Did three sections. Vacummed each section and mopped. There stood three bare walls.
Attacked each section. Electrical next. Mounted new switch boxes.
Next each section. I put up new drywall called green board for mold resistant. Cut my windows out with a zip saw for drywall. Vacuumed each section as I went.
Next was the plastering.
Taped and plastered each section.
I had a corner wall by our fridge. I repaired it too.
Then came the paint. Wife chose the color. Wiped walls down and started painting.
2 days later. I received my upper wall kitchen cabinets.
I finally took my zip wall system down.
Put up my ledger board for wall cabinets. Mounted my new kitchen hood.
Mounted my 3 wall cabinets and removed my ledger.
Next was to finish my outlets for my lights and switches and GFCI.
Do to some errors on delivery off my lower cabinets. I had to wait 3.5 weeks. But that gave me time to finish or touch up remained work.
Bottom cabinets finally arrived.
Drove to the store. Got my orders loaded up.
4th week. I finally started installing lower cabinets.
During the week while we were waiting for cabinets to arrive.
Our fridge and stove failed.
Luckily we found a set and got them installed.
Lower cabinets finally installed.
Next counter tops?
After a few days of decisions by my wife. She settled on tile counter tops.
Bought all of the materials I needed. 2 weeks of final work including working my regular schedule. I was done.
I've never attempted to do anything of this level before. Lots of planning and work by myself. I finished. I am 68 yrs old and I'm feeling good.
I still need to finish some plumbing..
My son lives 1.5 hours away. Plus he has a job too. But he did stop by to help wire my new shed. ❤
I am 100% for having wood burners, but in saying that I have endless amounts of firewood trees on my property so it only takes a bit of grunt work...which is free...Plus I really enjoy cutting wood.
It seems a few people in the comments think you should have kept your fireplace. The point those people are missing is that you are not allowed to have an old fireplace in Nelson because of the air pollution. I loved what you said about people saying, "You're crazy to get rid of your fireplace. If the world goes upside down and there's no electricity, you won't have any heating!" Welcome to Nelson, Scott. Lotsa people here think the end of the world is coming.
he also wont have hot water as its a continuous flow it needs electricity to spark and stay running for temperature control. Also log fires aren't great for your health the smoke particles hang around for up to 3 days and increase your chance of smoke related cancer alot. so i fully support his decision to remove it.
The Green commies have taken over the asylum. All are heavily invested in the "climate change" scam. I'll die before I let anyone take my wood stove away from me. Mental is the key part of environmentalist. Stay strong, masculine and free. No to the convid and climate change scams, 🔨🌲🇮🇪🇮🇪
Since you're on the south island power is abundant. But you could complement with solar but that again is expensive. We have gas ducted and it is in the same range monthly cost. Wonderful heat though. I am contemplating to add a small heat pump to utilize the power from our solar. Especially for cooling in summer.
Nice transition to the add. I see Jess has taught you well grasshopper!
Sounds like a great deal compared to cost where I am. I went with gas heat / outdoor compressor for cooling only. I like the warmer air from the gas, and part of the year it is too cold for a heat pump to operate efficiently. Here, gas is also cheaper than electricity.
Wow! Those sandwiches looked scrumptious.
Nice job on the demo.
Lovin the musical selection Scott!
Love your mate reaching the ceiling, and you need a step ladder. 🤣
Our single heat pump installed in our lounge was $3500 NZD.
Our woodsman fireplace was $4800 NZD and another $700 for a through wall heat transfer that blows the heat down the hallway.
So $9k for hearing the lounge area. The rest of the house is hated indirectly by radiance.
$13k to have every room indirectly heated isn’t bad. A friend has a modern new build with ducted heat pump and their power consumption over winter was only $35 a month as once the house is up to temp it takes very little to maintain it at that level.
Hi Scotty & Jess we have gas heaters in our home its piped along the road. Nice and clean no mess. We spent $11,000 on the two heaters floor and roof insulated. Being an old house 1922 build its not insulated in the walls. We can have that done for around $7000 but no double glazing. Thanks for a great episode love your work always.
Double layer your curtains to the floor, will give you effective insulation over your windows
Kind of happy and sorry at the same time to see an older fella still on the tools. Not a fan of air source heat pumps. But I'm in Croatia, where it can be -10 c in winter. Had to work in a house with it during winter, never felt warm.
I spent about $6500 AUD for my 14kw heat pump about 4 yrs ago. Plus another thousand or so for ducting, vents grills ect, and installed it all myself. Just had the fridgey do the gas lines. Seen it done plenty enough times on site to give it a shot. They are the most efficient option, just a matter of keeping the heat in my 1960's fibro shack 🙄. Improving it bit by bit.
13 & 1/2 G bangers sounds pretty good for ducted heat pump system. Having a house that is all warm (and always warm) is somewhat of a novelty in NZ - crazy huh!!!
I agree with your thought that if power is no longer available for your heat source then sh!t has got pretty real and you will have bigger problems.
For us (at Lyford) we can’t rely on power as we have too many power cuts (especially in winter) - often for a day or more. We rely heavily on our log fire (helps we have 3 Ha of bush from which we can extract free firewood). We are looking at building here and hope to have a heat recovery system in a passive house and a smallish log fire. It is the most efficient way for new builds (not realistic for old houses with poor thermals). Capital cost is about the same as ducted heat pump, but would operate 100% off grid.
Oh and smart move putting washing machine on concrete - I was all busy posting a comment to you to make sure you did put washing machine on concrete when you said that’s what you are doing.
Ducted is less invasive, but high wall units connected to single or multi-split compressors is more efficient. I have 7 highwall units on 4 compressors and only need to heat/cool the rooms I need, plus the minimum power draw is less on smaller units. Last month power was $235 and several units are on 24*7 - in Auckland.
G,day Scott and Jess from Sydney Australia.
I think you missed some ceiling insulation, every bit helps reduce heat loss.
I do like the new heat pump system all the same.
🌏🦉
Radiant floor heating is pretty efficient way. But makes more sense when building a new house. As in renovation one would need to take up all the floors.
I have 12kW in my house but I'm not restricted with lot size like Scott because in my case I needed about 900m (close to 1000m2 space) of piping in ground for the heatpump.
Machine itself costs about 9K another 5K goes for the accessories. 3,5K for laying down the ground piping. But then one would need in house radiant floors.
We’ve got a similar sized house to yours Scott, the cost for us is about $60/month. We’re fully insulated and double glazed. I remember being in London paying £200 a month on gas!
Heat pumps are great and you’ll get air conditioning in the summer! 😊
Great segway to the sponsor Scott. My wife and I enjoyed that one.🤣
I'm thinking a second floor addition would look real nice.
Hi Scott, love all your videos. I did a similar job on my first home. Me, this Kiwi DIYer who doesn't do things by the book, it's nice to know now how it should have been done haha. I removed my fireplace from the bottom...😅
To keep the world in balance… “Scott Brown here and on today’s exciting episode.” He forgot…😜👍
I would definitely go with a heap pump as well. But use a ground-to-water type instead and use in-floor heating (Hydronic). Both the things increase efficiency a little and are just nicer to live with.
That seems to be a really good price. Here in Scandinavia they are in such high demand that they cost double. Due to a lack of qualified installers and the component shortage
You mean a radiator central heating system, the way New Zealand is behind the times it will be another 20 years before it gets there.
@@steventhomas9461 Nope. No radiators. Just tubes in the floor. It's much nicer to walk on. You can have a lower room temp but still feel warm and the in floor heating requires a much lower water temp because of the large surface area. Meaning your heatpump doesn't have to heat the water up to as high a temperature. This raises your COP factor massively
For example. A Panasonic AQUAREA. Looking at the datasheet. When going from 55C to 35C water in the house heating system. The COP factor goes from 3,07 to 4,85. That is a massive difference.
This is obviously if you were building new.i don't know of a house that age with pipes in the floor ?
So not an option in this case?
We did a retrofit in my sisters house. Same thing as Scotts house. Wooden floors and a crawlspace. Was hard work, but it really paid off. Could remove the radiators and got a ton of insulation in there afterwards
Can we collectively try to get the recipe for that toastie Jess made, looked exquisite
3years ago it was 10k for a ducted system for my home here in Southland, but regrettably went for 2x heatpumps and a heat transfer to utilize exess heat from the fire. Looking back the ducted system would of been worth it 👌
Love watching your videos. Would recommend next time to use a disposable suit so you don't put all the cement dust through the washing machine when you wash your overalls/clothes
Question for you Scott? Can you say how much you would of charge for dismanteling the chimney if you were doing it for a client? Like how many hours, cost for the garbage bin, fan rantal and pipes etc etc. Thanks in advance.
Like this one that is combination of reinforced sections and cast? 2 days 2 guys work plus equipment and removal. Not including any remedial wall and roof construction. Should be around $3K
@@DiscoFang I agree, about 3k
As someone who lives in the city on the Danube, I approve the music choice!
This is all awesome content but in watching other videos about windows efficiencies and stuff, any window no matter the rating equates to having, basically, a hole in your wall. Double glazing, triple, glazing, blah blah. It doesn’t matter cuz they won’t work after ten years. Brent Hull has a wonderful video on 100 year windows you must watch. All that said, will you be adding an interconnect for a dual fuel power generator for those days without power now that you don’t have a chimney? After the hard freeze here in Houston I got a genny and made it run on natural gas and it runs the whole house. 10000 watts. Keep the content coming. Love the show. Smoko time for me now. 😂
I paid $12,600 in 2020 for the same system in Taupo. So with inflation your 13.5k is right on point.
Also look into solar, it pairs quite nicely with a heat pump. Getting one put in next month. We should half our power bill with an 8kw system on a north facing roof. Pays back in 9 years. Some of the banks are doing good low or no interest loans for this stuff now.
We installed an air/water heat pump a few month ago in Sweden, it cost about 21k NZD which is about 2% of the house cost of a house where I live in Sweden. Compared to heating with gas it should save about us about 30-50% on the heating cost. Around 6 years ROI.
You have the best brand ducted system going Scotty! Your in safe hands with MEA
I am in the NW of the US and taking conversion into account...the price for your heat pump is right in the ball park.
Geo thermal heat all the way 👌🏻 One of the perks living on a volcanic island in the North Atlantic 🌋🇮🇸
Geological Thermopumps is popular here in Sweden. Since they are far more efficient in keeping the house warm cheap. But it does require a house ,as you say, well insulated.
I have regular power cuts in England.
Without a fire I wouldn't have been able to heat the house or cook food for three months during autumn and into winter last year.
Zip wall is a great product, is s what I use for dust protection here in the states. It is unnecessarily expensive for mostly plastic. It is great and very easy to set up though. You can put up a whole dust wall up to 12 feet high by yourself in a matter of minutes. Its legit. Glad that you can get it way over and way down there. Like dyown undah? Just kidding, I know you kiwis don't necessarily like to be confused for Australians.
$7800 US is pretty good. I just had one installed in our house and it was $13000 US. It’s a retro fit and a big house. I think it’s a 3 ton unit. Worth every penny.
I paid $13K for a Mitsubishi HVAC system so my heat and AC come from outside the house through their inverter heat pump. Our house is 3600 square feet so we needed their hyper heat system. The company I retired from used these for their clean rooms and never had a failure. From what I understand it will provide up to 100 percent of heating capacity at 5° F and continue operation down to -15° F even without auxiliary heat. The first year we had it we got hit with days over 100F and the winter got us below zero. It just kept on going. The unit inside the garage is the fan and control system. We were previously on gas heat and heating in my state is usually hydroelectric and gas. There are some homes that are heated by wood. When we switched we noticed our bills drop down, even with AC on the really hot days.
I was dead keen for that Lossnay system but the quoted price around the same as what you paid put me off. I went with a 8kw heating AP71 heatpump in a central location for $5k with the outside unit out the back of the house.
It’s over spec’d for the room but it has brought up the temp up in the whole house. The house is a fully insulated 1940s weatherboard. Power bill has only gone up $25 a month. A good compromise in the end.
Hi Scott. $8,500 AUD install all in for Ducted Fujitsu 10kw Reverse Cycle down here in Melbourne Australia. Glad to know I wasn't totally ripped off!
Hi Jonny, any chance you could share the company you went with? I have struggled to find a quote less than $10k in Melbourne
in the UK, air source heat pumps are typically around the same price for a small domestic unit, which is probably the size you'd need for a house the size of yours 😊
So, on your last video I commented on how effective a shop vac can be at capturing dust. That, um, doesn't really apply here LOL. Very well done on the tent & fan.
With all the insulation you’re adding you might consider optimising your heat/cool schedule to minimise your power bill.
It’s an idea taken from tech connections but essentially it’s using off peak electricity pricing plus your homes air as a thermal battery to
minimise heating and cooling.
In summer you overcool (minimum comfortable temp) the home just before offpeak pricing ends and then set it to your max comfortable temp immediately after. The home should maintain a comfortable temperature for a long time before needing to kick the AC back on.
In winter you do the opposite.
If you have solar you can also set a midday “recharge”.
So glad to see you so successful Scott. I KNEW YOU COULD DO IT.! Pamela Marshall
Hey Scott, 2 inch air gap under roof sheathing so intake soffit air can flow to ridge vent to keep roof from over heating and adding stryofoam as insulation, I used 6 inches of the blue colour, 2inches per sheet x's 3 sheets . It turned out to be a cathedral ceiling of the porch and the difference in comfort is amazing. You want your HVAC system to not be in an overheated air space so it will not take that heat surrounding it and heating the air conditioned air that you want in the Summer months. It is a common error to put an HVAC in a very hot attic. Not a smart Idea. Insulate the roof underside of your attic to make it a comfortable living space and your HVAC will not have to work as hard and you will also see that your energy bill will be reduced. I look forward to an episode where you will show how to insulate the roof sheathing with that 2 inch air space. Trust me, I have done it and it is AMAZINGLY comfortable in the heat of our Summers here in Atlantic Canada. Keep up the good work to you both from East Canada.
Those small dust extractors are really only good if they’re right next to where you’re working. For big rooms you need to get 2-3 big ones, pump air in with 2 and extract with 1 so you’re basically forcing the dust out
Can you run the dust extractor on the other end of the ducting? So that the noisy fan is outside of the house?
Yes I would pay that much, would love more info on where you got it. I'm in the Bay of Plenty and when I looked online I only found them in the 20-30 thousand price range. I also removed my fireplace because the price of firewood is ridiculous.
I took out a similar chimney in a 50's state house a few years ago and the blocks were very crumbly so only used a sledge hammer
Beautiful! Just beautiful.
Rather than using electricity to make heat through a resistor, like a oven or fan heater or oil column heater etc, the AC is using electricity to compress the refrigerant, which then wants to steal heat energy out of the environment. It can steal more heat energy than the electricity could provide, all we need to use electricity for it moving it around which is a lot easier than trying to heat it directly. Its basically allowing a chemical reaction happen, but controlling where it happens. The RUclips channel Technology Connections has a whole bunch of videos explaining this topic in depth, since it also is the same process by which fridges and freezers works.
But long story short, you are using electricity to control something that can move heat better than the electricity can, hence you get values of 400% efficiency or better (1 watt in, 4 watts out). Also like how a fuel tanker can move more fuel than the engine uses, to facilitate more power in a remote town than the truck engine produces.
We have air to water heat pump with underfloor heating downstairs. Havent had a winter with it yet but looking good so far. I think its around €7000 to install but there are grants of 3000 to assist if upgrading
