What Is a Heat Only Electric Boiler?

The EHS Heat Only Electric Boiler is a modern electric heating solution designed to work alongside a separate hot water cylinder. Unlike a combi boiler, which provides heating and hot water directly from the unit, a heat only electric boiler focuses solely on delivering efficient central heating while allowing hot water to be stored and supplied from a dedicated cylinder. This makes it an ideal choice for larger homes, properties with higher hot water demand, off-gas buildings and projects looking to transition towards low-carbon electric heating.

Range-rated from 2kW to 12kW, the EHS Heat Only Electric Boiler can be configured to match the specific heating requirements of each property. Rather than selecting from multiple boiler sizes, installers can use a single boiler model and adjust the output to suit the application. The result is greater flexibility, simplified specification and improved energy efficiency.

At EHS we recognise the growing demand for eco-friendly heating and hot water solutions.

Electric combi boilers can be run from electricity produced from renewable resources such as wind or solar power, which means that you can run your boiler completely free of CO2 emissions.

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

By 2050 the UK Government are aiming to generate 100% 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!

Electricity prices are currently 3 times more than gas, but as gas is phased out and electricity becomes the fuel of choice, prices per unit of energy are likely to reach parity in the not-too-distant future, and as an electric boiler is 98% efficient, it will be cheaper to run.

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