What is a hybrid or dual-fuel system?
A hybrid system pairs a heat pump with an existing gas boiler. The heat pump handles most of the heating on milder days, and the boiler steps in during the coldest weather or for fast hot water. A controller decides which to use.
It can be a sensible stepping stone for homes where a full switch would mean large changes, such as new radiators or a hot water cylinder. It keeps the comfort of what you know while cutting back on gas use.
It does add complexity, with two heat sources to maintain, so it is worth weighing up. Our boiler repair and maintenance pages explain how we look after the heating side.
