In a typical UK household, over half of the money spent on fuel bills goes towards providing heating and hot water. As fuel costs rise, having an efficient and cost effective heating system is vital, and it’s one of the main steps you can take to reducing your carbon dioxide emissions.


Modern boilers are more efficient for several reasons, but their main advantage is that they are all condensing boilers. All well-maintained boilers burn their fuel very efficiently, but they inevitably lose some heat in the hot gases that escape up the flue. A condensing boiler has a larger heat exchanger, so it recovers more heat, sends cooler gases up the flue and is more efficient.

Sometimes the flue gases get so cool that the water vapour in the gas condenses out, hence the name, and even more energy is recovered from the condensing vapour.

Choosing the correct energy efficient boiler for your property can reduce your gas bills by up to 40%!

What boiler should I choose? 

Most old gas and oil boilers are regular 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 buy a new regular boiler, and keep your hot water cylinder, or 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. Which is better for you will depend on different things:

Your hot water usage

Large families using lots of hot water are likely to be better off with a regular boiler, whereas smaller households using less may be better off with a combi boiler.

Space in your home

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