I bought a 4 ton air to water h/p with 80 gal. buffer, no fittings or extras direct from china, delivered to home, usa, $3500. heating guy here so did myself, I use a regular thermostat outside to trigger oil boiler, which h/p is hooked into, when o/d temp is under 40F. as unit is a little under sized, and quicker heat recovery. works great in shoulder months.

Great video, thanks for sharing your experience. 4630kWh for heating/cooling over a full year. To put it into context, was the heat pump providing 100% of the heat for your home or did you have other heat sources? What climate zone are you in? What temp do you keep your house at? Do you have oil usage to compare to from previous years? Is the heat pump providing your domestic hot water? Is the heat pump only running the 3 fan coils or do you have radiators/baseboard also? Finally, around what temperature water do you have the heat pump set to? I'm guessing its based on outdoor temperature since you have the fancy controller, so around 32F what water temperature do you use? Those things will influence how close you get to those manufacturer published specs. Great job and thanks again for sharing!

So you used to pay $35.38 / MMBtu, and after spending $22,000 you pay $33.79 / MMBtu? So you only save $65 a year after spending $22,000?

I'll be sure to check out your play list as there isn't much out there for A2W heat pump installations in North America. Comments: it seems like A2W systems in North America are less common and more expensive than the ones I see people getting in England and other places in Europe where they are much more common. The brands are more mainstream (e.g. Daikin & Mitsubishi) while A@W systems here are seen as niche. I'm in the process of buying a house with a 20 year old gas boiler & indirect water heater (no air conditioning) and I'm seriously considering going all electric as well as I can put solar on my roof. $$$-wise for a "5-ton" system the equipment cost isn't so shocking as I was quoted $20k for a 2-ton replacement a/c gas furnace.

Great job thanks for these videos they are life savers, I am doing the same thing, I have bought my heat pump 6 ton and buffer tanks and domestic hot water tank, please can you post a list of the accessories that you used, brand and links of where you bought them.

Oh man, that really added up! I'm glad you did the calculations to show that you really are saving money in the long run, but boy, I hope you never have to spend all that money ever again!!

I spent about $20K before tax credits for an air to air system at about the same time, so the price is not too shocking. But in just equipment costs per the invoice, about $12.5K. I'm in Colorado and had a gas forced air system. The Mitsubishi system is called 4 ton but really 54,000 BTU/hr. It has a matching air handler. Over a year, it uses about 6200 kWh for the heat pump and about 950 kWh for the air handler. Maybe 75% of that usage is heat, and really influenced by the amount of time under 10 degrees F. It works down to -20F but works really hard.

Thanks for sharing. Looking at the slope of your iotawatt chart - looks like a little less power consumption in summer. Would be cool to see outside temp vs kwh. btw iotawatt is great - has influxdb integration which works well with grafana for much faster data parsing. Just pita to learn grafana.

Thank you for the detailed information. You saved all the labor cost also.

I did the same install, but kept my high efficient boiler and oil burner and double wall oil tank, hooked in series with air to water h/p for the real cold days, and backup source.

Nice problem solving! 👍

Do you know what gloss these windows are painted with? (Exterior) And the siding?

Are you sure a shower current is going to stop water from getting outside the shower?

Sister all new studs

Awesome job!

Love it!!

Glad you were able to solve this mystery. You are always so calm and determined.

Since you did ask for opinions, I have to STRONGLY agree with just about everyone else about NOT painting the kitchen cabinets and woodwork in the kitchen. That would totally destroy the soul of the room. And that furnace is a GEM! PLEASE PLEASE PLEAS don't do anything to that brick!!! I could see replacing the mantle and the trim at the ceiling, but paint or anything else on that brick would be a crime. I'd definitely get that fireplace, and all the others, in working order rather than sticking a wood burning stove in it. I don't understand why people buy houses with so much character only to rip out or paint over everything that gives it character.

Good problem solving! It's so good that you have a big basement with lots of space to work. In California, we really don't have basements at all. I don't know if it's due to our earthquakes, or just newer houses with less space. I really like your older houses on the East Coast from that perspective. You're preserving a treasure! :)

How do u like this system. I'm thinking about getting this heat output for my in floor heating

Installed in-floor radiant heat back in 2004. Unfortunately I am the only person who knows the system. 3 plumbers looked at it and said “ no thanks”

Isn't it a well cap- I mean not original but be careful. there might be a hole. my papaws well cap or pump house looked like that/

Those fireplaces are phenomenal!👍🏻

Love the makeover and now I want to paint a room this color too! I had exactly this same pantry set up and I can't encourage you enough to put the doors back on the upper cabinets. I too, took them off, and over time it was a very bad move. Looks very cluttered and messy as it's an entry point and you'll see it all the time, but mostly because there is no way to keep dust, hair, ect., off the shelves. Especially because it's an entryway. Unless you want to constantly clean out the cabinets, it just looks messy.

I'm so impressed with your work!!! It's beautiful!! (Julia's Mom)

You did a great job. Brilliant color selections. I feel like I am walking thru a home in Sturbridge,Mass.

You did a wonderful job. It looks great!

That green linoleum was 1940s vintage...I would have totally bought that from you in pieces if necessary!❤

Absolutely gorgeous, a lot of hard work, but it was well worth it❤❤❤

That is absolutely beautiful. And to include one of my very favorite songs. Ah. 💕

Beautiful space, congrats 👌

I could not tell. Is there a screen at the termination to keep bees and birds out. Definitely needs insulation for pipe sweat. Nice job! New subscriber. Just happened to see your channel starting with original house tour.

San Antonio, TX has a large public pool that is spring fed. Use to swim there during summers. Great public pool and free. I no longer live in San Antonio.

Great video! I need to do the same thing in my 98 year old home. I wish my attic was as open as yours, though. My house has a massive loft, and we have an extended attic running through a knee-high wall on one side. It's going to be a pain to fish ductwork between the joists, but it'll beat having to open the window everytime I shower. Especially now that it's snowing in Michigan!

Great job! Really eye opening to see all of the work behind the scenes of a simple bathroom fan! So necessary. Happy Thanksgiving to you and your family! :)

Lead paint removal is better left to professionals prior to occupation.

Pa told me sawdust was a sign of termites. Did they get into that wall? Maybe?

Thanks for sharing! Great video. We have a 1763 home in Maine we just moved into and been looking for information on this. Lots of spots around the house to repair. Never heard of the charcoal board! Great for the bottoms. And that inferred paint stripper. Wow. Again great info. Thanks again!

Please, please don’t paint all that beautiful woodwork white. It would not fit with a colonial house at all, and is wonderful. Just refinish. People are going away from white. The brickwork adds do much character we’re.

I would not paint the kitchen trim white.

That kitchen was a 1970s remodel, including the cabinets. I'd have left the fireplace and made an eat in kitchen with a nice table. There is something to be said for a fire in the morning, a table to eat at, in a nice kitchen on a cold winter's day. These houses are meant to be multi-generational, a trend we are seeing more and more. Work on it for the family, then work on a separate living area for your old age, with no stairs. 😁Love the Brittany btw. We show, hunt and breed Brittanys. Looks like that old timer has had a good life. Something we are always glad to see.

It looked as if it might be a dovecote

Having purchased and moved a center chimney colonial house way back in 1980 and re-constructed it in 1991-1997, I can see why you are excited to dig into this project. The house has some very nice original features. A few tips: 1. Let a professional deal with the lead paint. Let them do the tests and the abatement. This is nothing you should mess with. Especially with children living in the house. 2. Focus some attention on the HVAC systems and insulation. Blowing heat through the walls, windows, and fireplace openings will put you in the poor house. 3. Secure the basement against moisture...if possible. 4. Unless you are thinking of buying tools to become a home handyman, consider hiring professionals to do the work that seems to be the most labor and tools intensive. 5. Hire an electrician to do the inevitable system re-work. My saying? Doing your own plumbing may only mean you get wet. Doing your own electrical work....could kill you. Just a few thoughts from a guy who has 40 years of experience doing this stuff. Good luck. RW Upstate NY.

I have some very similar windows here in Sarnia Ontario, home built around 1950's. 1 south west facing window sill nosing is completely missing/rotted, the storm window pane fell out right after we bought the house earlier this year. Cutting up some new nosing tonight. New storm windows are hard to come by. I really like the old windows but the storm windows are around $400 each shipped from USA.. we have opted to DIY install some cheap second hand windows for now. I have kept all the old windows to work towards a full restoration in the future including new storm windows.

Get more period furniture when yo7 can and make sure to hide the television, or better yet just get rid of it. Better to live a more full life without television interrupting your family life.

Build an outdoor kitchen with that other fireplace and get that chimney fixed and lined when you do the others.

I grew up in a house like this which was also built in the 1780s. We had a 3 hole outhouse too!

Great teamwork!

Is it R410a refrigerant? Such a shame you did not go with R290. It's just become available. Works down to -35C and heats to as high as 85 C. R410 is being phased out since it a major greenhouse gas. R290 has a GWP of just 3 and a smaller pressure and charge so it much more efficient and climate friendly. R410a runs the cycle hat much higher pressures so its harder on compressors and requires more kW per unit of energy produced. Don't get me wrong, what you are doing is admirable and much better than burning fossil fuels for our children and their children. I'm enjoying your build. I just ordered a 5 tom ATW R290 heat pump to replace my condensing gas boiler. Mine is simple. I have an indirect tank that feeds my 14 zones of in concrete floor heat and contains a coil running threw it for domestic hot water. I had 8 zone valves on thermostats and no have disabled them after tuning the flow through the loops. I now have one thermostat and my house always has warm floors in winter and is super comfortable. It's a 20 year old ICF so it's super insulated. I suspect that 5 ton will be too large. Next year I will run the cooling lines central high velocity fan coil unit to convert from R410 central air. I think you will be pleased with the system you have built. Removing air from hydronics usually requires a bleeder at the highest point in the system. Since you have a variable pump you should be able to speed it up to flush out the air. Cheers!

Was this kitchen redone in the 60s craze for Early American? IF it was original wood I'd say leave it and the window is gorgeous with all the panes but that scallop thing over the sink if very 1950s-60s.
