I want a central heat management system based on a cascading heat pump.
Liquid circuitry would run through a house to key locations. The waste heat from a refrigerator and freezer could feed the hot water heater or floor heating. A gaming computer or console would feed waste heat in. Anything with a compressor, cooling fan, heating element, or flame could get more efficient.
@mattferrell@neverbeaten I've had similar thoughts: it seems so inefficient to have the fridge pumping out heat, making the surrounding air warmer, and our hybrid water heater sucking the heat in, but a different part of the house, making that region colder. There ought to be some way (even just forced air transfer) to move heat around more efficiently than whole-house convection. And you get more even overall air temp in the house to boot.
