Hi all ...
Say ... I am in the process of getting bids on getting a central air unit with a variable air handler and a thermidistat (both temp and humidity control).
The last bid gave me the option to go with a Heat Pump or straight electric on the furnace side.
I've been trying to recall my high school physics on this one and I'm guessing that a Heat Pump is basically just an air conditioner in reverse ... chill the outside and pump the waste heat inside (I guess you save on waste LIGHT that way from heating elements or something of the sort).
Anyway ... I have a fairly small condo ... only needs a 1.5 ton unit in the first place.
Question ... when a heat pump is running (say it is 45 - 55 degrees outside), what % savings does one see with a heat pump vs. straight electric.
TWO ... say it is 10 degrees outside (or 0) are the electric back-up elements in a heat pump furnace system significantly less efficient than the electric heating elements in a straight electric furnance?
Thanks!
