Heat Pumps
Just installed a new HPDHW for my hot water . Bought it a few years ago and
now stopped coal use. Will have to see how efficient it is over the next months.
I have a GE 80 gallon tank so it will satisfy all our household needs.

Nice setup! Especially the outdoor unit under the deck - no problems with snow.hotblast1357 wrote: ↑Sun. Sep. 04, 2022 12:34 pmGot my heat pump installed yesterday, we’ll see how it does! Hoping to hold off lighting my boiler till maybe mid December??
How low of an outdoor temperature will this unit handle?

How did you get the air/moisture out of the lines?hotblast1357 wrote: ↑Sun. Sep. 04, 2022 2:05 pmI did it myself lol the outside unit came pre-charged.

I know that is how it is traditionally done, but as this was a DIY kit I wasn't clear if there was some other method. Most DIY homeowners don't have a vacuum pump hanging around.

The “mr.cool” DIY brand is a true DIY as the lines and indoor unit comes precharged.
With my DIY style, I know a lot of people that just crack the low side and open the shut offs and “push” the air and moisture out lol but installing two inside units and spending $3,000 on it I figured buying a $160 vacuum pump was well worth it lol and gave me piece of mind confirming I didn’t have any leaks as I cut and flared the copper to fit. The inside units were charged with nitrogen, so that you “the homeowner” knew if there is any leaks before installing it, by take off the caps and hearing nitrogen come out.

I am looking forward to hearing how well it works for you.

Not hot enough to run the A/C now?
Is your electric cheaper than your coal per million btus each?
How much coal would you save if you in fact hold out until December?

Only 60 yesterday and 63 today so we actually have the heat pump on this morning, electricity is .15/KW, I paid 217/ton for coal, but having the ability to just press a button and get a little heat in the morning vs lighting and maintaining the boiler is a huge thing.
I would burn around 2-3000 pounds of coal on average from September 25th till December 25th. And in the spring I can let the boiler go out sooner.
With the price of coal I want to hoard all that I have for the extreme cold times. We have enough till 2025 winter if we burn what we normally do, maybe with this now I can go til l 2026..
And not having to put in two window A/Cs every year and listen to them stupid things hum is priceless in itself lol

Those inverter heat pumps are amazing. Produce heat even at 0 degrees outdoor. My son has 2 Mitsubishi units with 6 indoor units the outdoor unit is so quiet it’s unbelievable.

The heat pump will really shine when you only need a few hours of heat each day. In that weather the boiler just idles and is only about 50% efficient. As it gets colder the heat pump becomes less efficient (and the boiler efficiency improves). In your area the average temperature doesn't get below freezing until late November, so I think you will do pretty good with the heat pump until then. You will need to keep an eye on the temperature in your boiler building.hotblast1357 wrote: ↑Mon.

I am really looking forward to your results. You have been in the house a while and have good records of electrical and coal consumption, so it should be easy to see where you land.
