How do Heat Pump Pool Heaters Work
A Heat Pump uses electricity to operate but they also use the sun-warmed air which contributes to the efficiency of the unit. Heat Pump Pool Heaters do not generate heat.
Your existing pool pump circulates the water through the heater and warms the pool. The FAN circulates air through the outer EVAPORATOR AIR COIL that acts as a heat collector. The liquid refrigerant in the air coil absorbs the available heat in the ambient air transforming it into a gas. The refrigerant gas is then pumped into the COMPRESSOR. When this warmed gas is compressed, it intensifies or concentrates the heat like a magnifying glass in the sun. This intensely hot gas is then pumped into the HEAT EXCHANGER CONDENSER where the actual heat transfer takes place. As the pool water passes through the heat exchanger, the hot gas gives up its heat to the cooler pool water. The refrigerant returns to a liquid state and is pumped through the EXPANSION VALVE then into the evaporator air coil to start the process all over again.
