> I use my 10k gallon pool to dump heat from the house into until its thermal capacity has been reached That sounds amazing. I can't seem to find any commercial solutions for that, only a DIY-ish toggle between a heat exchanger cooled by the pool pump and the usual condensor. Is that what you've done? Guessing this would also work for heating during winter; use the pool water when it's above ambient? While looking, I did come across a tangentially related problem I thought was interesting too: cooling your pool in summer.
