I have a 11,000 gal (41,000L) indoor swimming pool. The previous owner was heating the pool with propane but this seems to be costing us a small fortune, especially during our Canadian winters. The pool surface is area is roughly 16ft x 27ft, with a 15ft celling. There is a mini split installed in the pool room for heating. There is also an air-to-water heat pump used for humidity/heat recovery. I have 2 Water-to-Air heat pumps on 2 separate closed loops that heat my home. The heat pumps are a 5-Ton Nordic R-65-HACW and a 2.5-Ton WaterFurnace. I have nine (9) wells each 150-ft deep : 5 wells for the 5-ton HP and 4 wells for the 2.5-ton HP. Both heat pumps have desuperheating capabilities already installed. They have copper coils. My question is the following: would I be able to use my desuperheaters to heat my indoor swimming pool without compromising my home heating capabilities? Would this be an efficient way to heat the pool? If so, what would be the best setup? I know pool chemicals and salt will corrode copper. Would it be best to use a heat exchanger?
