Electric Combi Boiler

Electric Combi Boiler. Should I have one installed in my own property?

Millions of us have been heating our homes and hot water with gas for longer than we can remember, but with all this talk of gas boilers being phased out to meet climate change targets and for people not connected to the National Grid, an electric boiler could well be worth considering.

Electric combi boilers work in a similar fashion to gas combi boilers, only they run directly on electricity as opposed to natural gas. Consequently, electric combi boilers are becoming increasingly popular for new build flats or smaller properties that do not have a mains gas supply. As well as being exceptionally reliable, they are highly efficient with rates around 99% compared to 89 – 95% for most gas boilers. With no moving parts, electric combi storage boilers are incredibly quiet and their maintenance requirements are kept to a minimum. Despite being larger than a standard electric flow boiler, the electric storage boiler makes use of an additional built-in tank, that is both space saving and provides powerful mains pressure for showering and bathing.

Advantages of electric boilers

For millions of homes across the UK without access to the gas network they are a viable heating alternative and bring with them several other less talked about benefits. In addition, if you are able to power an electric boiler with renewable energy, you could be reducing your carbon footprint and/or lowering your energy bills.

There is no denying that the price per unit for electricity is higher than gas. But, electric boilers certainly have their advantages and do provide other ways to make some savings. They’re cheaper to install than other boilers and you also don’t need to have it serviced every year.


Here’s a few more benefits of installing an electric boiler.

No gas or oil needed
If you’re not connected to the National Grid and have no access to gas an electric boiler is a sensible option. If you don’t have space for an oil tank an electric boiler is also a great alternative as they only need an electricity supply to heat your home.

Highly efficient
With electricity, you get out what you put in. In other words, as electric boilers do not need to burn fuel to produce heat, they don’t lose energy through waste gases. This results in an efficiency rating of 99% compared to 89%-95% for most gas boilers.

Lower emissions
Electric boilers are a much ‘greener’ alternative to gas boilers. They don’t need to burn fossil fuels to generate heat and don’t release waste gases. If you’re looking to reduce your carbon footprint, an electric boiler could be just the ticket.

Cheaper to install
Thanks to the absence of waste gases, an electric boiler does not need a flue or condensate so the installation is much easier and is likely to cost less than a gas boiler installation. Have a look at our Essential Guide to Electric Boiler Installation for a bit more detail.

Flexible installation
Not only is an electric boiler installation cheaper, they don’t have to be installed on external/outdoor walls like gas and oil units. So within reason, you can choose where to put your new electric boiler.

No risk of a carbon monoxide leak
Gas boilers produce harmful gases during operation, which are safely expelled out of the flue but could leak, with an electric boiler you don’t have to worry about any harmful gases leaking.
