With new and improved Inverter technology, the heat pump very cleverly has the ability to continuously regulate its own thermal power flow (which can add 15% – 20% efficiency when compared to conventional technology.)

A traditional heat pump either works at maximum capability or is switched off, as the compressor's speed cannot be varied. In order to regulate temperature a thermostat is used to measure the water temperature and switch the compressor on when the water temperature is too far from the desired temperature.

The Heatinverter uses a rectifier to convert the incoming AC current to DC and then uses Pulse-Width Modulation of the DC current within an inverter (electrical) to produce AC current of a desired frequency. As the speed of a brushless motor is synchronised to the frequency of the AC current it is thus possible for the Heatinverter compressor to be run at different speeds. A microcontroller then samples the pool water and ambient air temperature and adjusts the speed of the compressor appropriately.

The effect of eliminating stop-start cycles is to increase efficiency, extend the life of components, and eliminate sharp fluctuations in the load the air-conditioner places on the power supply. This reduces the demand on the compressor which in turn reduces the running cost and improves efficiency.
