At EHC we recognise the growing demand for eco friendly heating and hot water solutions and all of our products are designed with this in mind.

Owing to the fact that Electric Boilers can be run from renewable resources such a solar power, it means that your boiler will run completely free from CO2 emissions.

Electric Boilers are also 100% efficient which means that for every 1kW of electricity you use, you will receive 1kW of heat.

Moving to electric is easy, as you don’t need to replace any of your existing pipework or radiators.

By 2050 the UK Government aim to generate emission-free electricity. Electric Heating will be a major facilitator in reaching this goal and in 2020 the Government pledged 40GW of wind generated electricity in the UK by 2030. This is enough electricity to power every household in the UK!

By moving to Electric Heating, with a renewable energy tariff you’ll not only be moving to carbon-free heating, but doing your bit to heat for a renewable future!
