Air is drawn by a fan across an evaporator which is filled with very cold (-20 degrees) refrigerant gases. The gas absorbs heat from the air and is then passed though a compressor which further intensifies the heat. This intensely hot refrigerant gases (over 100 degrees) are then passed through a heat exchanger which transfers the heat from the gas into water which is pumped into your pool or spa.
Dual Loop Screw Core Titanium Heat Exchanger
Thermo Smart heat pumps boast a unique double loop titanium heat exchanger with counter current technology. Water and refrigerant flow in opposite directions and pass the heat exchange tubes twice ensuring faster heat absorption and up to 20% better performance. We also use screw core ribs on the inside of the heat exchanger tubes to maximise water contact and overall efficiency. The titanium heat exchanger is not only super efficient, it won’t rust or corrode (as long as normal water balance is maintained).
