For many homeowners, deciding between a gas and electric boiler is a difficult decision. In this article, we will look at how each type of heating system works as well as how much each one cost. Making our final recommendation about whether you should replace your current boiler with either an electric or gas version.

Do gas or electric boilers heat your home better?

If you’re looking to heat your home, the answer is simple: gas boilers are better. Gas boilers heat your house faster because they burn hotter and use less energy than electric ones. This means that they can raise the temperature of water faster than an electric boiler would be able to do it. And since we need hot water in order to have warm showers or baths, this makes gas boilers better when it comes down to heating you.

But there’s another benefit: because gas boilers generate heat through combustion (burning), they’re also much safer than electrics. Electric fires are very common because electricity itself tends to spark fire easily if something goes wrong with its wiring system; whereas with a gas system, there’s no risk of catching anything alight unless something goes wrong with its flue pipe which carries fumes away from where people live.



Which is more suitable for larger homes?

If you have a large home, then gas boilers are the best option for you. They can heat up to 5 bathrooms at once and provide hot water to every room in your house. On the other hand, if your house is small with just one bathroom and one bedroom, then electric boilers would be more suitable because they use less energy than gas boilers do.

Electric boiler vs gas boiler efficiency

A gas boiler has an efficiency rating of 90%-92%, while an electric boiler can have an efficiency rating of up to 92%-96%.

The efficiency of electric boilers vs gas boilers depends on the type and size of your home. Typically, electric boilers are more efficient than their counterpart. Because electric boilers use a heat exchanger to convert electricity into heat energy. Which then heats water in an insulated tank. This means that they don’t require any combustion gases to generate heat.

Advantages of electric boilers vs gas boilers

Electric boilers offer some distinct advantages over gas boilers that can make them a better choice for your home.

  • Electric boilers are cheaper to run, as they use less energy and don’t require the cost of buying gas or heating oil on an ongoing basis. This makes them especially beneficial if you have limited funds for your monthly bills.
  • Electric boilers are also more environmentally friendly than their counterparts. They release fewer pollutants into the air during operation, which means that there’s less of an impact on climate change overall (and therefore fewer negative effects on human health). This makes them ideal if you want to help protect our planet while still enjoying all the benefits of having hot water at home!
  • Finally, electric boilers tend to be quieter than gas models on average–a bonus if noise bothers you when taking a shower or relaxing in bed at night!

Disadvantages of electric boilers vs gas boilers

Electric boilers have some disadvantages that you should consider before purchasing one for your home.

  • They are more expensive to run than gas boilers. Electric boilers use electricity as their primary heat source, which is more expensive than natural gas or propane. You’ll pay more for your energy bill each month if you opt for an electric boiler instead of a gas one.
  • They aren’t as efficient at heating water as gas-fired units because they have lower BTU ratings (British thermal units). If you want hot water quickly and efficiently, then it makes sense to go with a model that uses natural gases instead of electricity as its primary source of heat–but keep in mind that this will increase the cost of operating the unit over time!

Cost of running electric and gas boilers

Electric boilers are cheaper to run than gas boilers. This is because they use up to 80% less energy, which means you’ll need less fuel and electricity to heat your home.

Gas boilers can be more expensive in the long term as well if you don’t factor in the running costs of each type of boiler. For example, if your gas bill is $500 per month but an electric boiler would cost only $200 per month then this could save you money over time!

Cost of installing electric and gas boilers

The cost of installing a gas boiler ranges from $500 to $2,000 depending on what kind of system you choose and how many options you add to your purchase. This includes labor fees for installation as well as any materials required for the job (such as piping).

The cost of installing an electric boiler depends on whether or not you need extra wiring for it to run properly. If not, then the price will be around $1,000. However, if you do need extra wiring then expect this type of appliance to set you back anywhere from $1-$2k. Depending on how extensive your home’s electrical system is.

Which is easier to maintain?

In terms of maintenance, the electric boiler is the clear winner. Electric boilers have fewer moving parts, which means that you can perform your own maintenance tasks without having to call in a professional for help. You’ll just need to check your water level once every few weeks and make sure that there isn’t any sediment building up at the bottom of your tank.

Gas boilers on the other hand require professional servicing every year or so to ensure they are running safely and efficiently. This includes cleaning out any dirt or debris from inside its components. As well as checking for leaks in pipes or fittings (as these can lead to carbon monoxide poisoning).

Should I convert the gas boiler to electric?

You may be wondering if it’s possible to convert a gas boiler to an electric. The answer is yes, but you will need to check with your gas supplier first. In some cases, they will allow you to convert the system and in others, they won’t. The conversion process isn’t as simple as just installing an electric heating element in place of your current one either. It requires professional installation and wiring work that could take several days. Depending on how big your home is and how many radiators there are throughout it.


We hope that this article has helped you to understand the difference between an electric boiler and a gas boiler. As you can see, they both have their advantages and disadvantages. If you’re looking for something that’s easy to install and maintain then maybe an electric boiler is for you. However, if you’re looking for something with better efficiency then maybe go with gas.
