Just installed. "Hyper Heat" meaning that it extracts heat from air temperatures below zero F rather than the older types would require resistive heat below about 40 deg F. SEER of 22.5. Another choice was a 9000 btu unit of SEER 25.

The unit may not be big enough to supply all needed cooling and heating. The window unit, I believe, is about 18000 btu which is sufficient for cooling the area. The major impetus is to not have to build fires in the stove when heating needs are moderate. Current infirmities have made fire tending tedious and painful.

Full heat capacity down to 5 deg F! I'm now thinking the 18000 btu unit might have been a better choice, though less efficient. I was first drawn to the 9000 btu unit because it is more efficient than the purchased 12000 btu..

I've been running the 12k btu unit now for over two months and I'm well pleased with it. I have in hand a similar 9k btu unit that I intend to put in my bedroom. Together, I think the two units will both heat and cool the entire house. For back up cooling, I will leave in place the two window units: a 18k btu in the dining room and a 6k btu in the bedroom. I'm thinking ahead for the winter in case my limited mobility problem does not get better and I don't feel up to tending a fire in the winter. Even with improved mobility, I will likely do a lot of winter heating with the heat pumps.
Electric energy is generally not a problem. During the day, I produce and send to the grid at least 10 times as much as I can hope to squander on heating and cooling. My only (slight) worry is that, if grid is down, I may have not be able to heat and cool as much at night as I would like.

Looks like the next two mornings will give you the opportunity to see how effective it is to replace the need to build a fire.
ReplyDeleteLooks like it might serve as may sole source of heat down to mid 30s. The past few days, I've allowed it to run more than necessary; it has used less than 10kwh/day, generally around 500w with lows in the mid 40s. The only surprise has been difficulty moving the warm dining room air into the living room.
