Question:
So I was wondering, is it fesable to combine that with a central AC
> air handler so that one would be cooling the home while
> simultaniously heating the pool?
Answer:
They've been selling HPs for pools for years, and making heat exchangers
for A/C condensers for even longer. In most climates you would be
heating your home while you are trying to heat your pool, so there isn't
any waste heat to recover.
