The Hydroroyal series of pool heat pumps also carries a unique design TXV (Thermal Expansion Valve) which has been optimized for R-410A refrigerant to precisely regulate the flow of refrigerant through the coil, achieving maximum efficiency, especially at lower temperatures and allowing lower cost of operation.  

The Hydroroyal Heat Pump extracts free heat from the earth’s atmosphere, a renewable energy source, and mechanically upgrades it and transfers it to the pool water. The process is clean and safe for the environment. 

There are no harmful emissions or dangerous carbon monoxide fumes. Even its controls are designed to work in conjunction with solar panel system for the ultimate high efficiency pool heating system.  A true solar heat pump!
