I am wondering if there would be a way for me to have water warmer than the air in winter pass across the coils of my heat pump? I have constant ground water under my basement that i pump out with a small pond pump and i am wondering if on say a 20 or 30 Degree F day if I passed warmer water over them or near them it could help the heat pump use less electricity? also considered a rocket stove heating water nearby to run past the coils. i really wish i could have a zone of coil to directly affect either by submerging in warm water or something? same would go for AC in summer. it would be cooler than the air outside. kind of making the system more like a ground source pump?
