How gas boilers work

Here’s a quick overview of how gas boilers work:

  • Gas enters the boiler and is ignited
  • The heat from the flame is transferred to a heat exchanger
  • The heat exchanger heats water, which is then pumped around the central heating system
  • The hot water is also used to heat the hot water supply
  • The flue sends combustion gasses outside

The two surveyor's who came out were very professional and personal, we had a laugh about one being a Wigan warriors fan and we're Rhinos fans lol. Then Rob who came out to fit the boiler again very professional and personal, very tidy workmanship. Can't thank your company enough, new boiler fitted in less than a week and easy to deal with.

Gas boiler FAQs

We’ve answered some of the most commonly-asked questions about gas boilers here, but please speak to the team if you have any more.

Will I have to replace my gas boiler after 2025?

No, you don’t have to replace your gas boiler after 2025. The news of banning gas boilers only relates to new build properties from 2025 onwards. No current legislation says you have to replace existing gas boilers, so if this is how you are heating your home, you don’t need to worry.

What is the best boiler for gas?

This will depend on various factors related to your home, such as its size, location, and energy needs. Grant Store is a Vaillant-, Worcester-, and Ideal-approved installer, so you can trust our advice when the time comes to upgrading your existing boiler system.

Is it worth buying a new gas boiler?

Figuring out if it’s worth buying a new gas boiler depends on things like:

  • The age and efficiency of your current boiler
  • Your budget
  • Your heating needs

If you’re torn between keeping your current boiler or having a new one installed, just speak to a member of the team. We’ll be happy to talk you through all your options.

How many years does a gas boiler last?

The average lifespan of a gas boiler is between 10 and 15 years, but it can vary depending on several factors, such as the quality of the boiler, how well it is maintained, and how well it was installed.

Does a gas boiler need to be serviced every year?

Yes, you should have your gas boiler serviced at least once a year, as this helps you ensure it’s working properly and has no leaks. Missing services could affect your boiler’s performance, lead to it breaking down, or even invalidate your warranty.
