Supporting the decarbonisation of home heating

Gas boilers are responsible for 60% of carbon emissions in the UK and 22 million homes in the UK use them. The government is making significant steps to help reduce the impact by banning gas boilers in new builds by 2025.

Along with heat pumps, electric boilers offer a smart and alternative way to help decarbonise home heating. They run quietly and are compact in size which means you can install them almost anywhere. So whether you are looking for an electric boiler to replace a gas boiler, need help with off grid options or looking for a perfect instantaneous hot water system, you are in the right place.

No fossil fuels. No flue.

Electric boilers don't burn natural gas so there is no need to install a flue which speeds up installation time. Changing to a green energy tariff will help reduce your carbon footprint even further.
