Knowing the pros and cons of electric and gas boilers is important for choosing the right heating option for your home. Each option has its pros and cons in terms of energy efficiency, cost, and actual heating performance.
Gas boilers are by far the most popular choice in the UK, with around 78% of households using them to heat their homes. But electric boilers have a number of important advantages that can make them a more affordable option. So which one is right for you?
What is an electric boiler and what is a gas boiler?
Both gas and electric boilers can heat your home. But there are some important differences in how everyone performs. Toast chief engineer Nick Tandy explained. “Boilers burn natural gas fuel to generate heat for central heating and domestic hot water. Electric boilers, on the other hand, convert electricity into heat instead of burning fossil fuels.
MyJobQuote heating expert Matthew Jenkins said the heating process was almost identical for both boilers. “Both of these systems heat the water in your home and then direct it to your radiator and faucet for hot water.”
So why would you choose one of them?
Which boiler is more expensive, electric or gas?
Gas boilers are almost always more expensive considering the initial cost. Checkatrade estimates the average price of a combined electric boiler in the UK to be £1,100. Then there’s the installation, which is usually much cheaper for electric boilers that don’t have a chimney or gas water pipes. Depending on whether you are converting to a similar type or moving your boiler, the cost of installing a gas boiler can range from over 1,000 euros to nearly 4,000 euros.
At the time of writing, British Gas is offering £2,695 to supply and install the same gas mixture in a used car. The boiler delivered was a Worcester Greenstar 8000 Life 35kW Combi with a five-year parts and labor warranty. In this case, the boiler is located on the first floor, and the house has two bathrooms and up to 10 radiators for heating.
Operating Costs – Electric Boiler vs Electric Boiler Gas
If operating costs are the biggest concern, choosing between gas and electric boilers can be more difficult. Currently, electricity is more expensive than natural gas as a fuel. Based on the UK average of 16.6 p/kWh, running a 12 kW electric boiler for 70 hours per month costs £139.44, according to Checkatrade. Now, a similar gas boiler will cost you £90 a month.
Nick Paulson, heating expert at PlumbNation, explains that if you opt for an electric boiler, “you’re using more electricity, which means your monthly bill can be very expensive.” It should be noted, however, that due to the UK’s current The crisis is pushing up gasoline prices, a situation that could change in the coming years.
Maintenance Costs – Electric Boiler vs Electric Boiler Gas
While electric boilers are more expensive on your bill, they can be much cheaper when it comes to maintenance. “The main advantage of them is that they have no moving parts, which means they are less prone to failure and therefore less maintenance,” Nick Paulson said.
Unlike gas boilers, electric boilers also do not require annual maintenance, which makes them less expensive to maintain. If you’re wondering how much it will cost to maintain your boiler, it can cost you up to £100 a year. This is the equivalent of £200 if the boiler fails.
Gas boilers can be cheaper to buy and install because they are more common and therefore more widely available. But cost aside, gas boilers can be more difficult to install. “It was a huge and expensive experience,” Paulson said. “It can take weeks for professional plumbers to install new pipes and radiators, which involves raising floors, damaging walls, sometimes with limited hot water and heat, sometimes weeks.”
On the other hand, Heatable Gas Safe engineer Ben Mars points out, “Electric boilers are easier to install because, unlike gas boilers, they don’t require a chimney or condenser piping.”
Are gas or electric boilers more environmentally friendly?
There is no doubt that if you are looking for the most environmentally friendly boiler, an electric boiler is the right choice. Electric boilers do not emit carbon dioxide because they heat your home, which is a considerable drop compared to boilers that burn fossil fuels and release harmful carbon dioxide into the air. In fact, an estimated 40% of CO2 emissions come from UK households, and gas heating accounts for a large portion of that figure.
This also means that electric boilers can also win in terms of safety. Gas boilers carry the risk of carbon monoxide leaks, so you don’t have to worry about electronic options. “However, it is worth noting that with proper maintenance and selection of a gas safety engineer, the risk of carbon monoxide leakage from a gas boiler is very low,” says Matthew Jenkins.
Is a gas or electric boiler better for heating your home?
This is another clear winner. If you want to heat your house faster and more efficiently, choose a gas boiler. “A boiler heats a house much faster than an electric heating system,” Nick Paulson said. “That’s because the burner produces maximum heat from the moment it’s turned on. “
Electric boilers generally can’t compete here (yet). This is because their flow rate (the amount of water delivered to the tap in one minute) is much lower than gas boilers. “This means they often cannot provide good heating and hot water for the average British home with poor insulation and insulation,” Ben Mars revealed. “This means that electricity is only really profitable in the long run when it’s heating a house. Or in a well-insulated house.
It should also be noted that very little gas is available. On the other hand, if you have an electric boiler, a (more common) power outage will affect your heating and hot water supply.
Electric Boiler vs Air – Final Judgment
Overall, you need to make the right choice for your home and budget.
Most experts now believe that a gas boiler may be the better option for most UK homes. This is because they heat your home faster and more efficiently than electricity. Of course, this is the main function of the heating system in your home. Not only that, but they also give you much lower monthly bills than electricity bills. Gas boilers are easy to replace if you break them.
However, electric boilers also have many advantages that gas boilers cannot meet. Electric boilers can help you significantly reduce your carbon footprint and require less maintenance. Additionally, they pose no risk to the safety of gas boilers and are easier to install.
Also, there has been a lot of talk recently about a possible ban on gas boilers in 2025. This is part of the government’s “No Internet by 2050” plan. So it might be worth starting and installing an electric boiler now. The ban has not been confirmed, though, so don’t panic if you have a gas boiler in 2025. You will not be forced to remove and replace it.
