Electric Boiler: Cost, Efficiency & How They Work

Electric boilers: What are they and how do they work?

An electric boiler may be the ideal solution for heating your home if the option of gas is unavailable where you live, or you want the benefits of having an electric-powered heating system, such as a quiet boiler and more installation flexibility.

What is an electric boiler

An electric boiler uses electricity rather than gas to heat hot water. Just like a gas boiler, it will heat up the water that warms your radiators, and the water you use in the kitchen and bathroom.

They can come in various shapes and sizes, but in all electric boilers, you’ll see water running through the system to be heated by a heating element – similar to the way a kettle works.

Advantages and disadvantages of electric boilers

Electric boilers can be convenient to install and can be energy efficient, but there are some drawbacks when compared to a gas boiler.

Electric boiler system

Advantages Disadvantages
Can run quietly Typically small systems, so may struggle to heat larger properties
Small, compact systems that can squeeze into tight spots Potentially higher general running costs
Can be easy and cheap to install Potentially higher costs when using energy in the daytime, if you’re on a split tariff
Don’t need to be placed on an outside wall, as there’s no flue or gas pipe It may be expensive to change to a gas system later down the line
Can be energy efficient – little heat is lost in the process of heating the water Energy isn’t always accessible when using a system with storage heaters

Gas boiler systems

Advantages Disadvantages
Potentially cheaper running costs compared to an electric boiler Gas supply may not be available near you, especially if you’re in a rural area
No need to store any fuel Additional costs are involved as the boiler must be professionally serviced every year
As gas systems are so popular, you may find that it is easier and quicker to get it fixed or serviced Commonly need to be placed on an outside wall, or will need more piping to reach an outside wall if the boiler is put on an internal wall
It may be easier to upgrade from a gas system to a newer, more efficient, condensing boiler Gas boilers can be louder than electric boilers

How to purchase an electric boiler

It’s best to buy an electric boiler through a trustworthy vendor or company. We don’t install electric boilers but we may have an alternative to suit the needs of your home and your lifestyle.

If you’d like a little more information about what type of system might be best for you please call us on 0203 763 2682 or fill in the contact form at the bottom of the page.

Should you use storage heaters with an electric boiler?

Deciding whether or not to use storage heaters may be one of the main quandaries you have when considering an electric heating system.

Electric systems with storage heaters allow you to save up thermal energy overnight, potentially letting you take advantage of cheaper tariffs if you’re charged differently for day and night energy use.

But, storage heater systems can be more expensive to install, and as you’re guessing how much heat you’ll want to use the following day, you run the risk of being caught short if the temperature is lower than expected. You can of course still store up more energy during the day, but it may be more costly.
