Electric boiler vs Gas boiler: the pros and cons of each

Gas boilers used to be the main option for home central heating systems, but there are now other energy choices available depending on your own needs and requirements.

Depending on your personal circumstances, electric boilers can be beneficial if gas isn’t an option, or if you simply want a greener solution without having to commit to the hefty price of renewables.

We’ll be looking at the pros and cons of the two rivals to help you make your decision.

Gas boiler pros.

95% of UK homes are centrally heated and most have a gas boiler, which ensures there are many Gas Safe registered engineers readily available to install, service or repair your boiler when necessary.

There are also a variety of consistent and reliable gas boiler makes and styles to suit your needs. Gas boilers can be powered by natural gas, liquid petroleum gas (LPG), or are 20% hydrogen-ready. This accessibility of fuel means they are often cheaper to run than other types.

They can also fit around your time schedule and generate heat and/or hot water to suit a variety of homes, from flats to large houses.

Gas boilers are reliable too. Yet, it’s important to maintain it to ensure a consistent smooth running to avoid any breakages or irreparable damage, which could come to a hefty price.

An annual service can save you time, effort and money in the long run. If the boiler isn’t working properly, this can be flagged during your boiler service. This will ensure that any issues don't get worse, which could leave you with a heft bill.

Thankfully, Swale Heating offers boiler cover and service plans to keep you safe in the knowledge that, if anything goes wrong, there is always someone there to hand. Click here to read about your options.

The pros of an electric boiler.

They are almost 100% efficient. Current gas and oil boilers are closer to 90-94% while electric units are 99.9%.

Electric boilers are perfect for properties that aren't connected to a gas mains. Smart and compact electric boiler designs also mean little to no disturbance in your home, and the lack of indoor tanks allows your home to be opened up to more living space and storage.

Electric boilers are also much quieter than gas counterparts, so they could even be fitted in a bedroom without causing disturbed sleep.

No mandatory servicing is required, and you don’t need to obtain a safety certificate compared to a gas boiler. However, an annual service is recommended to track down potential failures and save you time and money in the future.

Going electric can be a much greener option as not as many CO2 emissions are created, compared to a gas boiler which contributes directly to fossil fuels and your carbon footprint.

Indeed, with fuel and CO2 emissions now a huge topic for society and our government, electric boilers and renewable energy sources are increasing in popularity in an attempt for the UK to become carbon neutral. 

Finally, a new electric boiler is easier to install, thereby minimising disruption.

The cons of a gas boiler.

Gas boilers feature in most homes, but the fuel cost is rising and there is concern about how older models will fit into regulations and restrictions put into place to help combat global warming.

However, due to advancing technology, gas boilers are becoming more eco-friendly thanks to the use of hydrogen. With heating technologies constantly updating, gas boilers are becoming a more sustainable and cost-effective choice thanks to constant innovation in the sector.

With gas boilers producing 215 grams of CO2 compared to an electric boiler's 207 grams, they are not as green as other alternatives and may lose out to more sustainable options, such as underfloor heating. However, this can come at a hefty price.

The cons of an electric boiler.

As things stand, electricity is more expensive than gas.

Additionally, heat from a gas system also tends to warm your home faster, minimising a gas boiler’s running times and costs - electric boilers work more slowly and energy bills can be higher.

Electric boiler installations can be faster but some parts and requirements may be more expensive.

And while you might be able to waive a yearly electric boiler service, this might not be the best idea if it stores up later maintenance and replacement issues.

Which is the cheaper option?

Electric boilers are typically more expensive to run than gas boilers, potentially around 3-4 times more.

Usually, non-electric forms of heating are much friendlier to your pocket but they aren’t always better for the planet.

Smart meters can help you see where your money is being spent, and how you can cut back and develop better energy budgeting habits, whilst reducing your carbon footprint.

Electric vs gas boilers: which is better for the environment?

Home heating accounts for 14% of all UK emissions*. Going electric is one way to combat that and, with the UK committed to and likely to regulate to cutting CO2 emissions to zero by 2050, many households are already reconsidering dependence on fossil fuel boilers.
