The Thermotec Inverter heat pump has a single speed fan and variable speed compressor . This means that they automatically adjust the speed of the fan and compressor to precisely match the heat demand from the pool.

The ability to adjust the output of the heat pump allows the Thermotec Inverter to deliver greatly reduced running costs with COPs of up to 13.
