An inverter heat pump will continuously modulate its output in the background to provide the consistent temperature. It reacts to changes in heat demand to make sure the fluctuation in temperature is kept to a minimum.

What is a modulating heat pump?

The modulating heat pump starts with a zero-amp starting current and continues to build until it reaches the capacity needed to meet the home's comfort. This places both the heat pump unit and the electrical supply under less stress.

How is a heat pump controlled?

The standard system controls for a heat pump are an adjustable controller and a room thermostat. ... If your heat pump provides hot water as well as space heating it is likely to have a two-channel controller for which will allow different temperatures and times to be programmed for each.
