Electric boilers use electricity to heat the water in a ‘wet’ central heating system in the same way as a gas boiler. An electric boiler gives you all the advantages of ‘wet’ central heating without the need for a gas supply. This can help reduce running costs and save you more money on bills.
If you’re considering an electric boiler installation or replacement, the chances are your property has no access to mains gas supply or there are gas boiler restrictions such as flues in voids or it’s a listed building. Because of this, electric boiler installation costs can vary.
Electric boilers range from 4kW to 14.4kW and the output you need will depend on things like the number of radiators and size of your home. Read our boiler buying guide for help finding the right boiler for your home.
Electric boilers are very energy efficient, with around a 99% efficiency rate for the user. They don’t require the burning of fossil fuels such as gas or oil to produce heat, and no heat is lost via flues or chimneys.
Over 2 million UK homes don’t have access to a gas supply or live in a property with gas boiler or flue restrictions. In these properties an electric boiler can be the smart choice to heat your home and provide hot water.
Electric boilers tend to be a lot smaller than gas ones and because they don’t need to be positioned near an external wall to house a flue, you will have much more choice about where you wish to position the boiler.
Electric boilers are cheaper to install that gas boilers because they don’t need a separate flue or chimney for waste emissions.
Electric boiler systems are quiet because they have no moving elements, so say goodbye to things that go bump in the night!
Electric boilers are easier to maintain, unlike gas boilers which have more mechanics included, electric central heating boilers don’t need annual servicing.

A flue uses a fan to take away noxious fumes produced by gas fired boilers and direct them outside, so they need to access an outside wall. Where boilers are located away from external walls, flues are more likely to run through ceiling or wall voids, or even through a neighbour’s property. After a number of deaths due to these flues being difficult to maintain new regulations came into effect in January 2013 which stated that Gas Safety inspections must include visual inspections of gas flues for every 1.5 meters or at bends in the flue. To comply, hatches need to be installed to enable an engineer to inspect the flues. This can be very expensive, as can relocating boilers and central heating systems. An electric boiler can be the answer to this problem, particularly in rented accommodation which require an annual Landlord Gas Safety certificate.
If you’re lucky enough to live in one of London’s beautiful listed buildings you’ll know there can be several restrictions on what you are allowed to do in terms of maintenance and home improvement. One such restriction we’ve come across in our years of installing boilers around London is the inability to drill holes to the outside of the building, resulting in a flue being almost impossible to install for a gas fired boiler. An electric boiler is a fantastic alternative to heat your home.
Electric boilers started becoming popular about a decade ago, replacing electric storage heaters. This means that many of the first models that were installed are now coming to the end of their lifespan. The new models are much more energy efficient so if you have one of the older models and you need an electric boiler replacement, you will save money on your energy bills.
