One of the main advantages of gas boilers is their affordability. They are generally cheaper to install and run than electric boilers, making them a more cost-effective option.

Gas boilers heat water and rooms faster and can be used for various purposes, like heating swimming pools, making them more flexible than electric boilers.

How can I determine if my boiler is gas or electric?

To identify whether your heating system is gas or electric, you can start by checking the labelling and documentation on the boiler. Another way is to examine the pipework and wire connections. Alternatively, removing the access panel and looking for the pilot light can also help distinguish between the two types. A visible pilot light indicates a gas boiler, as electric boilers do not have one.

Electric Boiler vs Gas Boiler: Pros and Cons

Gas boilers and electric boilers are two commonly used heating options for both residential and commercial properties. Both types of boilers have their own benefits and drawbacks. Below are some of the advantages and disadvantages of each:

Gas Boilers:

Electric Boiler vs Gas Boiler:

Efficiency, Environmental Impact, and Government Incentives in the UK

Gas boilers today use condensing technology, allowing them to reach efficiency levels of over 90%. A-rated boilers are required by law in the UK. Electric boilers do not waste energy or produce emissions, but the production of the electricity they use is carbon-intensive. 

However, electric boilers can become 100% efficient when paired with renewable energy sources like solar panels or air-source heat pumps. To achieve net-zero energy efficiency targets, the UK government may ban gas boilers by 2025, which could lead to an increase in the use of electric boilers. 

The UK government has introduced incentives to promote energy-efficient heating systems and renewable energy sources. Programs like the Renewable Heat Incentive and the Green Homes Grant provide funding for homeowners and businesses to install these systems. 

While there are alternative heating options available, such as biomass boilers and heat pumps, they may not be suitable for every building and can be more expensive. Ultimately, the choice of heating system depends on various factors such as property size, age, budget, and fuel sources. Seeking professional advice before making a decision is recommended.

Type of Electric Boiler

1. Dry Core Storage Boiler

Dry-core storage boilers work by heating up the bricks of your home overnight and transferring the heat from the bricks to the water tank to provide heating and hot water. Unlike other types of boilers, dry-core storage boilers do not circulate heat.

2. Electric Storage Boiler

Electric storage boilers are a reliable and efficient way to heat your home and provide hot water. Unlike electric combi boilers, they come with an insulated tank to store the heated water. While they may not be as space-efficient, they are a cost-effective option due to their lower electricity demand. Overall, electric storage boilers can help reduce energy bills and provide a dependable source of heat and hot water.

3. Electric CPSU

Electric CPSUs, also known as combined primary storage units, are a great option for buildings with high demands for heating and hot water, such as commercial buildings. These units have a high-pressure capacity and can provide large volumes of hot water and heat, making them an excellent choice for such settings.

4. Electric Combi Boiler

Electric combi boilers offer a practical and economical solution for central heating and hot water needs in homes. Their compact design makes them easy to install and maintain, and they come in a range of sizes to suit different requirements. 

Additionally, these boilers do not require any extra fuel storage tanks, which saves space. They are also eco-friendly and can help reduce carbon emissions.

Gas Boiler Types
