What Should I Consider When Replacing my Gas Boiler?

Here in the UK we spend on average almost £100 a month on energy bills*, with heating being a large part of this cost here in Cheshire. Installing an efficient boiler can make a big difference to your energy bill.

If your boiler is over 10 years old it may be time to think about changing to a more efficient gas boiler. Consider asking one of our gas engineers for their advice on whether your boiler is still giving you the heating efficiency you need.

When deciding which type of boiler is right for you there are some things to consider:

Choosing a Gas Boiler: Combination vs System vs Regular, Conventional Boilers

Many old gas and oil boilers are regular, conventional boilers that have a separate hot water cylinder to store hot water, rather than providing it directly from the boiler. When you replace your boiler, you can choose to keep your hot water cylinder and buy a new regular boiler, or you could buy a combi boiler that doesn’t need a cylinder.


A regular boiler is more efficient than a combi at producing hot water in the first place, but then some heat is lost from the hot water cylinder, so a combi may be more efficient overall.

A System boiler takes its water supply directly from the mains to heat your central heating system and produce hot water for a storage cylinder. System boilers work like a Regular (Conventional) boiler in that they need to store hot water.

When deciding which boiler is best for you, you need to factor in the following:

Your hot water usage

Larger homes and large families using lots of hot water are better suited to a System or Regular boiler rather than a Combi Boiler, whereas smaller households with a single bathroom may be better off with a combi boiler.

Space in your home

Combi boilers don’t need hot water cylinders and therefore take up less space in your home.
