webfarmerI wonder what the paybacks look like on this kind of step. It's probably not a bad idea in unheated basements but is kind of walking backwards a bit if they are heated or cooled space. If the space is heated they would be cooling it, which defeats the purpose. If the space is cooled it would have less heat to pull out of that space and efficiency would suffer. Of course, we have similar (reversed) problems with refrigerators but there are few alternatives for providing cooling in that way.

"Once connected to your existing water heater, the AirTap™ unit acts as a conventional heat pump, using a compressor (powered by a low-wattage electric current) to extract heat from the surrounding air, and then sending this heat through long copper tubes into an adaptor where it is dispersed in your water tank. This, in turn, heats the water to the same degree as would a gas burner or electric heating component, distributing the hot water throughout your home safely and efficiently.
If it takes four units of energy to heat water, AirTap™ utilizes one unit from an electric outlet, and three units from the surrounding air, reducing your energy consumption by about 2.5 times that of your current water heater."
