Heat Recovery Pool Heater | Compare To Solar Pool Heater | HotSpot Energy LLC
Instead of rejecting your home's heat to the air in the outside condensing unit, an alternate condensing unit is installed with a control valve to capture the waste heat and use it for heating a pool. Once the pool is at the control temperature, the valve would shift back to using the original condensing unit.

In theory, the heat rejection to the water would be more efficient for your home heat pump and there would be some energy savings. An advantage over solar is that with solar, the pump speed must be increased to provide sufficient head to move the water through the panels on the roof, the heat is free, but it takes more power to move the water. With this system a slower pump speed can be used saving more energy, combined with the increased efficiency the savings could be significant, in theory.
