What is a Hybrid Heat Pump?

A Hybrid Heat Pump combines a gas boiler and an electric heat pump to deliver reliable warmth while reducing carbon emissions.


Smart controls automatically select the most efficient source 
of energy - gas or electricity - to heat heat your home, based 
on temperature and demand.

By efficiently using electricity, particularly from renewable sources. A hybrid heat pump can significantly reduce your home’s carbon emissions compared to traditional heating alone.

Smart controls continuously monitor conditions and automatically switch between the gas heat pump and boiler 
to deliver the most efficient and cost-effective performance.

What is the gas hybrid Heat Pump allowance?

We are working with Warmflow, Vaillant & Alpha to deliver this programme.

If you already have gas heating, your existing boiler may 
be suitable, or you may be advised to upgrade it as part 
of the process.

In some homes, a hybrid heat pump can work alongside your existing setup, reducing the need for major changes.
