What are electric boilers?
Electric boilers are a method of heating hot water for your heating system using only electricity. A typical boiler uses gas to heat the water, whilst an electric boiler can be used in off-grid areas, or where a gas supply is either not wanted or not possible.
How do electric boilers work?
The boiler itself is very simple. It can come in various shapes and forms, but typically you will see a unit that has the water running through it, being heated via a heating element, just like you would a kettle. You will sometimes see long slim units that are designed to create maximum surface area to heat the water.
What are the advantages of electric boilers?
Electric boilers can be advantageous in certain situations. They are very simple pieces of technology, so they don’t need a lot of space, and can be placed almost anywhere in a property because they don’t need a flue or a gas pipe run to them. Very little heat is lost in the process of heating the water, so electric boilers are almost 100% efficient.
They tend to be easier to install and they obviously don’t need a Gas Safe engineer. The simplicity of the system and the installation process means that the overall cost of installation is going to be much less than a gas boiler.
What are the disadvantages of electric boilers?
Of course, if electric boilers were the best solution, you would see them everywhere, but you don’t. There are downsides to electric boilers – let me run you through the key points. Gas is considerably cheaper than electricity, at about 30% of the price. That means the cost of heating water using electricity is going to be a lot higher, even if you have a very efficient system.
That much is fairly obvious, but even when you compare electric boilers to other forms of electric heating, the electric boiler doesn’t necessarily come out on top. If you compare it to infrared, for example, an electric boiler will be more expensive to run.
Electric boilers probably have their place in certain properties. They are a simple, easy-to-install option but for many people there are going to be better ways to heat the home out there to look at. If gas isn’t an option, infrared, heat pumps or even oil boilers are all likely to be cheaper to run than electric boilers.
I,m not getting the answers I reguire if a water filled radiater was heated by gas or electric which would be cheaper to run
Hi Wayne
This is a simple answer for us – gas!
I wish to arrange for surveyor / engineer to quote me for installing a multipoint heater.There will be some slight alterations to the pipework too.
How do i arrange a visit please. The property is a maisonette in Sidcup,kent

Hi Any experience of electric boiler plus solar 4KW plus batteries. We have 4 bed house with solar and considering batteries. At present oil boiler
