Actually, if your objective is that the electrical energy input to your 2 hp pump be recovered for heating the pool water you are in luck! It already does. Friction in the pipe and pool as eddys dissipate convert the mechanical energy to heat. Some energy ~5-10% is lost by inefficiency in the pump motor and that is lost as heat to the air in the pump room. Pump inefficiencies are lost as heat to the circulating water, as is all of the mechanical (pressure & velocity) energy imparted by the pump on the water (assuming that the water just circulates and is not pumped from low to high elevation thus preserving some of the input energy as potential energy).

I am a novice about hydro power but it seems doable. Can > anyone help me get started on this project? Thank you. ------------------------ Yahoo!
