Re: Conservation of energy question - Reversing A/C compressor to create heat

If an A/C unit can move 3 BTU of heat for every BTU equivalent of

those with gas heating, some buildings still have electricity -- such as my

It can. you can buy an A/C sytem that is reversible, I have one myself.
Just the flick of a switch . The only problem with retreiving heat
from air is that when you need it most, (ie when it's cold ) the thing
is least effective. If you want a serious heat pump, heat has to be
recovered from the ground. There are such systems widely available.
The main snag being expense of installation.
