We installed it a few years ago to replace the original oil furnace in our house. It is still forced air and we had to have some of the ductwork upgraded as the house has an addition on it that added 50% more square footage but they never resized the ducts down the long all. The sir blows 95* out of the registers so it isn't as hot as a cumbustion type furnace, but our house has never been as cold as with the old oil burner. Our bedroom is in the new addition and has/had supplimental baseboard electrical heat and with the oil burner it was still cold. It cost close to $28k because of the ductwork and horisontal boring, but the 10 year mortgage and electric bill increase were far less than the monthly oil charge. Plus it keeps our hot water at 131* when it runs. We never knew the heating element went out of the water heater until spring hit and we didn't use the HP. I don't remember the electric element turning on since the unit was completely hooked up. Don't mess with the thermostat. Just set it and leave it. Summers are great, no noise outside and the compressor isn't that noisy inside.

Had I the choice to do it all over again, I would have done it sooner.

Paul, we were told we get 4 times the heat per kilowat compared to electricity, that may be where the 400% efficient came from.

The estimates we received were less than $900 per year in increased electricity for heating and cooling. We are probably a little higher, but we keep it warmer than the oil burner and cooler than the old A/C unit.
