Additional energy savings can be achieved through incorporating our hot water heating option into an installation. This option makes use of the efficiency of the heat pump for heating your water.

The efficiency ratings of The Great Aire Comfort System are exceptionally high. In the heating mode, there are models available with coefficients of performance (COP's) of up to 5.0. In the cooling mode, efficiencies range over 20 EER. The COP of the fully integrated hot water heating option can be as high as 4.25, which can significantly reduce the cost of heating water.
