What is the price of energy storage electric boiler

What is the cost of an electric combi boiler?

Electric boiler costs vary depending on the model and manufacturer. The smaller models typically range from £650 to £1,000, while larger models can cost up to £2,500.

Will electric boilers cost more than gas?

Currently, as of April 2025, under the current energy price cap, as decided by Ofgem, electricity costs are 4-5 times higher than gas per kWh. So, despite running at 100% efficiency, an electric boiler will likely still cost more than double compared to a gas boiler, new or old.

What is an electric storage boiler?

An electric storage boiler is supplied with a hot water tank either within the unit or as a separate unit. These boilers are often more expensive than direct-acting ones. A Combined Primary Storage Unit (CPSU) stores hot water within the boiler to meet demand quickly and at higher pressure.

How efficient are gas boilers in the UK?

In the UK, most gas boilers have efficiency levels around 90%. In comparison, electric boilers can reach up to 99% efficiency. This means that with a gas boiler, more energy is wasted in conversion, resulting in higher heating costs per hour.

What is the efficiency level of electric boilers?

Expect to see efficiency levels of 99% compared to around 90% for most gas boilers. With electricity, fuel isn’t burned to produce the heat, so that means there are no waste gases and lost energy. 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 does a storage boiler store?

The storage boiler stores the water once it’s been heated in a hot water tank. 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.
