Hybrid heat pump: collaboration with a boiler

A hybrid system combines a heat pump with a second source, usually a gas or oil boiler.

How it works

The automation decides which source to operate based on the outside temperature, load, and energy cost.

Advantage

It can maintain high power output at very low temperatures without requiring the heat pump to be oversized.

Critical point

Correct control logic is important so that the two sources work together without unnecessary consumption.
