Re: Hybrid water heater
I would question just how many folks have their waterheaters within the living space of the house to begin with. Yes, for those inside the house, the heat exchange waterheater probably isn't a good idea, though how much heat is really being pulled out of the ambient air, that was not made clear by the TOH program.
What about those that DO NOT have the water heater inside the living space, but rather in an exterior closet, in the garage, or in an unfinished basement next to the furnace? In each of these cases, no heat at all is being removed from the house, and in the case of being placed next to the furnace, it is utilizing gobs of otherwise lost heat. Most of the homes in this area have the waterheater in the garage.
According to the TOH broadcast, the primary heating comes from the heat exchanger, only under high demand do electric elements kick in to aid water recovery time.
So they are using electric to run a compressor for the heat pump stage and then a heating element or two for the water heater itself? And this is supposed to be how much more efficient than a straight heating element heater?
