The bridge from the fossil fueled past towards the carbon free future

Hybrids are often a natural next step for gas boiler installers to venture into the world of heat pumps

Hybrids remove many of the constraints associated with the application of stand-alone heat pumps in existing buildings using a heat pump for low temperature heat while depending on the power of a regular boiler for high- temperature heat when needed. Even on particularly cold days, comfort is guaranteed as the gas boiler can kick in when the heat pump cannot cope. Field tests show that the heat pump part of hybrid systems covers at least 70% of the annual heat demand.

Consequently, hybrids significantly reduce gas consumption and CO2 emissions, compared to a natural gas boiler. With the high efficiency of the integrated heat pump, this directly translates into as much as a 55% CO2-emission reduction.
