Replacing your old boiler

Boilers account for around 60% of what you spend in a year on energy bills, so an efficient boiler can save up to a third on your energy bills.

Why are new boilers more efficient?

Replacing an old gas boiler with an A-rated high-efficiency condensing boiler and improving your heating controls will significantly cut your home’s carbon dioxide emissions – and could save up to a third on your energy bills.
Why are new boilers more efficient?
A well-maintained boilers regularly serviced boiler 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 bigger heat exchanger, which recovers more heat using the heat from the flue gases to good use, then sends cooler gases up the flue making it more efficient.

The flue gases can get so cool that the water vapour in the gas condenses out. When this happens, even more energy is recovered from the condensing vapour, and the efficiency gets higher still.

Installing a new boiler
If it is time to change your boiler, then the first thing is to decide what type of boiler you need, in terms of size heating output, and hot water demand all need to be considered seriously before choosing.

The most suitable boiler
Most old gas are conventional boilers – they have a separate hot water cylinder to store hot water, rather than providing it directly from the boiler. When you replace your boiler you have a choice of buying a new conventional condensing boiler, and keeping your hot water cylinder, or buying a combi boiler that doesn’t need a cylinder, there are advantages to both which should be considered before deciding

A  conventional boiler is actually 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. The best option for you will depend on a the demands of your household:

What is the hot water usage  A large family house with more than one bathroom could be better off with a conventional boiler – a smaller house using less may be better off with a combination boiler.

If space is an issue? A combination boiler does not need a hot water cylinder, or header tanks and so requires less space.
If you are thinking of installing solar water heating? Most  combination boiler will not be compatible with solar water heating or cannot use it so effectively.
