This idea of a reversed air-conditioner has me excited, I have a 500 watt window air conditioner.
If it does provide 4 x the heat per watt then a space heater it will turn my 500 w air conditioner into a 2000 w forced air heater. I likey that idea
, It would heat my house on all but the most demanding cold days of the winter.
If i mounted it in my basement where i would not be disturbed by its noise i could leave it running on a thermostat all winter
Would ice build up be a problem ?
