What type of boiler do you need?

Get help understanding the advantages and disadvantages of the three main types of boilers and find the one that's right for your home.

Combi boiler

Combi boilers.

Great for smaller homes as they can fit in a cupboard and you don’t need a hot water cylinder or cold water storage tank, so they don't take up any loft space either.

More on combi boilers.

Regular boiler

Regular boilers.

If you often use hot water in multiple places at the same time, consider a regular or condensing boiler, linked to a hot water cylinder and a cold water storage tank.

More on regular boilers.

System boiler

System boilers.

Designed for homes with more than one bathroom, system boilers give you a constant supply of hot water to multiple taps. There’s no need for the tank in the loft either.

How well is your boiler running?

We all know when a boiler is running well, mostly due to how warm the house is and we've not just stepped into a shower that could freeze us in seconds.

Are your radiators not getting hot enough? They could have air trapped in them. The best way to deal with it is to bleed the radiators. Find out more on how to bleed the radiators easily in this helpful guide.

Of course, boilers do sometimes need replacing. With the average boiler lasting about 10-15 years, it's always good to recognise the signs of your boiler having issues. These include:

  • Your boiler is leaking water.

  • Your boiler is making strange noises.

  • Your boiler's pressure drops.

  • Your boiler's pressure is too high.

  • Your boiler is overheating.

If your boiler is doing any of these things, we've put together a handy guide to show you your options and whether you need to replace your boiler.
