Heat pump have made great strides and be effective down to 0 degrees and they always are more efficient than baseboard electric .

Yes and no. That cutoff is where the energy costs to run the heat pump are greater than regular electric. Their overall efficiency is largely based on outside air temps and it drops as it gets colder. It may be effective at 0 degrees but the benefit over standard baseboard is not that great at 5 degrees.

Cost compared to other fuels is whole other calculation. The calculator I have is not ideal for this but if you know the annual average efficiency compared to standard electric you can use it. If for example the average is 200% you can use 200% efficiency in the geothermal section and you will get somewhat reliable comparison to other fuels. The geo thermal calculation is fairly simple because it's pretty much set percentage all the time.

What the mayor says is true > My mind is stuck in the past 20 years ago where heat pumps just didnt work at 0 degrees.Now they do but They are not as efficient at 0 degrees. Hvac changes so quickly in technology its hard to be on top of it all.

Gets pretty "cool" here in New England during the winter months - I'd have to do more research on this subject. One thing for sure is, after heating with coal for 30 years, it might be tough for me to switch. I do love a warm basement, plus the coal has always been such a nice "even" heat.

I did a thing Monday… lol been thinking about one for a couple years, will save me some coal in the off seasons. Will be a fun project to install.

I read that the so called inflation reduction act has provisions that can allow homeowners to receive up to 8,500.00 rebate for installing a high efficiency heat pump that replaces a fossil fuel heating system. Homeowners can get an additional $4000 to upgrade their electrical system if required for the heat pump installation. There are restrictions based on your income. That’s a pretty significant enticement. Anyone considering a heat pump should certainly look into this.

So far though I cannot find a credit that will be paid without having a contractor install?? That eats up the savings or more!

You betcha H--a contractor of THEIR choice.

DIY installs not eligible for the tax credit? First I heard that. Could you please provide a link to that? Thanks.

I was just told by a rep. that came out to evaluate my house!!! I can only speak for NY--Check out NYSERDA.com

Thanks. I was searching for the IRS rules but couldn't find anything but I didn't look too hard.

Ma requires a contractor...
No DIY projects...
But does not say you can't work a deal with the contractor...

In Mass. you have to be a customer of one of the big investor owned companies as they are the contributors of the Mass Save program. My Son is a National Grid customer and is having 2 mini-splits installed for $10,500. His rebate is $10K. The curve ball is that you sign a covenant that you won't use your fossil fueled equipment except in cases of extreme cold or down time of the heat pump. I don't know where the enforcement of that would come from. Customers of municipal companies are S.O.L as they are not members of Mass Save.

Thanks for the info!

I don’t find it the least bit unusual or surprising that the equipment has to be installed by a licensed HVAC contractor. In Maryland at least you pick your own contractor. Just has to be a licensed HVAC contractor. My A/C is 23 years old but still working great. When it craps out I’m planning to get a heat pump and take advantage of this.

So I always figured these DHW tanks w/ heat pumps on them were a bit of a joke (taking heat out of the air you just heated w/ your resistance heat at worst) and then I read somewhere about retro fit units that you could at least set outside to take advantage of warmer weather. Can you retro fit one to a domestic coil in a boiler to heat your DHW over the summer? Keeping your boiler warm at the same time instead of a light bulb...

They are amazing. My HW from a 50 gallon HPWH cost less than if i burn coal even when the coal was cheaper. About $10 to $15 a month.Uses 550watts instead of 4500watts. Its takes about 2 degrees from the room its in which quickly recovers and the room is not heated. The best part is the free de humidification i no longer have to run all summer,another big savings. Going on 8 yrs now.
