An inverter heater, often found in HVAC systems like heat pumps and air conditioners, uses inverter technology to regulate the speed of the compressor motor, thereby continuously controlling the temperature by adjusting the heating or cooling output.
Inverter heaters can vary their output by altering the speed of the compressor. This results in more efficient energy use, reduced wear and tear on the system, quieter operation, and a more consistently maintained temperature, as the system can make subtle adjustments to output rather than completely shutting off or turning on.
