A conventional spa pool heater turns 1 kilowatt of electricity into 1 kilowatt of heat. The Azure hybrid heat pump turns 1 kilowatt of electricity into 5 kilowatts of heat, giving you up to 4 kilowatts of heat for free! Even accounting for the cost of running your pumps, overall running costs will be slashed by more than 50%. Over the life of your spa, this will lead to savings of thousands of dollars.

Heat pumps use the reverse cycle of a refrigeration plant to heat water. In effect, it transfers heat from a source such as air or water to the water which is to be heated. As in other refrigeration equipment, the heat pump system employs an evaporator, a compressor, a condenser, refrigerant gas, and an expansion valve within a closed circuit.
