Opting for an efficient boiler

Everyone wants to save on their heating bills, particularly in the wake of huge price rises, and one of the secrets to lowering energy bills is boiler efficiency. The more efficient your boiler is, the less fuel it needs to heat your home to your preferred temperature. And the less fuel it needs, the less you have to pay. In this article, we’ll look at how efficiency translates into cost savings for customers.

What is boiler efficiency?

Boiler efficiency is measured by how much fuel a boiler is able to turn into heating energy, compared with how much gets wasted in the process. Most modern boilers have an efficiency rate of at least 90%, with the most efficient reaching 94% efficiency. In contrast, older boilers may only operate at only 60-70%, meaning they have to burn through more fuel in order to heat your home.

How efficient is my boiler?

Under the Energy Related Products Directive (ErP), manufacturers must accurately label their boilers according to their efficiency. The scale runs from A+++ (highest efficiency) to G (lowest efficiency). If you have a modern boiler, you should be able to find this label and check the efficiency. Of course, boilers lose efficiency over time, so if your boiler is old, it may not be running to the same standard of efficiency as when it was new.

How do I maximise boiler efficiency?

Ensuring your boiler maintains maximum efficiency is fairly simple. The first step you can take is to engage a Gas Safe registered heating engineer to carry out an annual service, which checks that there are no faults or soot deposits that are affecting efficiency. You can also install a smart system, helping you keep your home heated effectively.

In 2018, the Boiler Plus initiative was introduced by the Department for Business, Energy and Industrial Strategy. This means that if you have a gas boiler installation, it must meet certain requirements. It must, for example, be at least 92% efficient under ErP, and include time and temperature controls, as well as other features.

How much could a new boiler save me?

With that in mind, a new boiler could save you a significant amount on your energy bills. A new A+ grade (ErP) boiler could reduce your bills by as much as 30%. If, for example, your current boiler is 20 years old, it could be as little as 75% efficient by now. Compared with a new one under the Boiler Plus initiative, that could be a difference of up to 19%, so although the outlay for a new boiler is high, it will save you a lot on your heating bills in the long term.
