I'll start this thread with weird ideas:
- two requirements
- The tech must exist
- there must not be a more obvious way to do it (that isn't already being used)
Mine first I guess.
A Water Heater That uses the heat off an A/C unit to heat the water. Then the gas/electric heater inside could be smaller, used for only reserve, or even eliminated!
- Plus since A/C is technically a heat *pump* then the heat it puts into the water would be from the surroundings and would cool the area around it. (also plus some inefficiencies, like the heat the motor produces and stuff)
(actually im pretty sure this exists but like I never see it even available to buy so I'm classifying it as not really existing. )
