What is an electric boiler?
These types of boilers simply use electricity rather than fossil fuels to heat the home’s hot water supply. Most suitable for small or medium-sized households they’re an excellent option for when there’s no mains gas, and there’s no room to store oil.
Electric replacement boilers are also popular heating systems for owners who rely on solar panels for their hot water supply.
Check out some of the other potenital ways to heat your in the future that are fast becoming options as opposed to gas boilers.
How do electric boilers work to heat homes?
An electric boiler is very straightforward in how it works. That’s because it works much the same as an electric kettle.
The boiler has a heating element which the water passes over and becomes hot. Electric boilers are quite often long and slim, and that’s because it enables a larger heating element to be fitted, resulting in the water being heated more quickly.
Why choose an electric boiler for central heating and hot water?
If you’re trying to decide which type of boiler is right for you, we’ve identified some big advantages to choosing electric over gas.
Electric combi boilers have no moving parts
When there are fewer moving parts, then there’s less to go wrong. So that means that electric boilers are much more reliable than gas boilers.
Are electric boilers easy to install?
Because an electric boiler doesn’t need a flue pipe, an electric boiler is much easier to place where you want it to be within the home. There’s also the advantage that you won’t need a Gas Safe engineer to undertake the boiler installation.
Electric boilers are highly Efficient
Electricity achieves an efficiency level that gas and oil boilers can only dream of. With electricity, fuel isn’t burned to produce the heat, so that means there are no waste gases and lost energy.
Expect to see efficiency levels of 99% compared to around 90% for most gas boilers.
This also means your central heating cost per hour will get you the best amount of energy, as less energy is being wasted in conversion.
What are the different types of electric boiler in the UK?
As with gas boilers, there are different types of electric boilers such as electric combi boilers, electric storage combi boilers, and electric system boilers. They all work in very similar ways to the gas boiler versions but use a different fuel source, and if you’re looking for something powered by electricity, check out our infrared panel heaters review which is also another option.
Electric Combi Boilers
The combi boiler works in precisely the same way as those powered by fossil fuels. So that means that hot water is provided as you need it removing any need for water storage.
Simply turn on your tap and your electric combi boiler will start heating up the water as it passes through the boiler using a heating element.
Likewise, if you want to heat your radiators, simply adjust your thermostat and your electric combi boiler will heat your home.
Electric Storage Boiler
The storage boiler needs a hot water tank to store the water once it’s been heated. This type of cheap to run electric heater does tend to be more expensive than combi boilers, but you’ll be able to take advantage of cheap electricity periods to get your daily hot water heated and stored ready for use.
Electric Dry Core Boiler
This is another type of boiler which is perfect for taking advantage of periods of cheaper electricity supply. The dry core boiler works by heating bricks which then release heat to be used for heating hot water and central heating.
