Going to be posting some data from my monitoring systems here.. Last fall i put in a single outside air source heat pump rated at 18,000 BTUs which has two indoor air handlers each rated at 12,000 BTUs. After realizing they where pretty efficient units, I put in two more smaller heat pumps in this fall, so that i can heat the entire house in the "shoulder" months here in Northern NY, not to be confused with "Upstate" NY lol. These are not top of the line brand name units, but honestly they all seem to share the same internal parts for the most part. These are Cooper and Hunter heat pumps.
SPECS:
House is 2,280 Square Feet., Located near Redford NY.
X1 18,000 BTU external air source heat pump that supplies two interior 12,000 BTU air handlers, one of these conditions my master bedroom and master bath, the other one conditions my living room, kitchen and dining room.
X1 9,000 BTU air source heat pump that conditions a bedroom and bathroom.
X1 9,000 BTU air source heat pump that conditions another bedroom and bathroom.

I have a electrical panel monitor system, and a temperature monitoring system.

lol they refer to some areas around here as little Siberia.
It’s a slick monitoring system for sure. It can do a lot more as well, smart outlets, EV chargers etc.

Longevity is the issue I have with them right now. Very expensive to have a HVAC guy install for a ~10 year life span. All the savings go into replacing your unit. A high quality install is crucial to a system that lasts even that long.

The biggest problem is moisture in the air when below freezing, once that happens the outdoor unit will freeze and need to be melted, which accounts for time that the indoor unit is not providing heat, once your house gets cold enough that the unit can’t keep up, then you have a problem. I don’t see a way of fixing that.
Nut, folks need to start doing things themselves, or no one is going to get ahead, these units are not hard at all to install, I’ve got 4,500 in total for all of my units plus my own installation.

I agree, only problem is the best makes will give you no warranty if self installed. About the only one that will give self installers a warranty is Pioneer and I haven't seen a model yet that compares to Fujitsu's specs.hotblast1357 wrote: ↑Mon.

For now the only “fix” is a second form of heat.hotblast1357 wrote: ↑Mon.

My next door neighbors son retired her Alaska stoker because it was rusted out and installed a multi zone heat pump.
She told me her first electric bill with the heat pump is $80 a month higher than usual but she was spending $500 a ton on bagged coal. that's less than half! She said she usually would go thru 3 tons of coal a season. they bought the Alsaka stoker in 1987.

Folks have to out weigh the cost of an installer with warranty vs DIY. I can replace my entire systems 3-4 time before it gets to the cost of a professional install. The chances of the systems failing that many times are extremely low, and it would only be one section as well, not the inside and outside units failing all together.

That's true enough. It's just my $400 coal stove is 30 something years old and going strong KOW.hotblast1357 wrote: ↑Tue.

I did rough calculations comparing fuel oil and electricity costs in my area of Maine. Heat pumps might save me $700 a year for energy, assuming a 3X multiple of BTUs available per kWh. I would still need the oil fired boiler for extremes of cold. So, it would take lots of years to break even on buying heat pumps and having them installed (and maintained?), even with the available subsidies. But huge numbers of people are having them installed. I'm not sure if I am missing something, or if everybody else is.
