New GE Heat pump based HWH, something for nothing?
As I am sure everyone is aware, GE has announced a new HWH based on a heat pump design claiming 2 or 3X the efficiency of a resistance based heater.
So far so good, EXCEPT for the fact that the unit is sucking the heat out of the ambient air. While this might be fine if the heater is in a garage or outdoor space, it is not so fine if the unit is placed in a basement or indoor heated space.
The BTUs have to come from someplace and in this case they will have to be supplied by the home heating system unless you live in the tropics or it is summer and you are running the A/C (in which case it will help you).
There is no free lunch and the laws of physics still apply.
Have I missed something here? If I have, please comment and enlighten me.
