Boiler ratings: what do they mean?

Boilers in the UK are accompanied by ratings rendered in different colours with different letters. While these may look nice, it is more important to know exactly what these ratings mean and the impact they can have on your energy bills.

Emphasis on efficiency

Boiler ratings were introduced in the 1990s as a government initiative alongside guidelines for energy efficiency from the EU. The aim was to monitor and reduce emissions from household boilers and to eventually eradicate old and inefficient boilers completely. The ratings we have now are a way of being able to compare the efficiency of different makes and models of boiler.

An inefficient boiler, along with other energy consuming devices in the home, can cost you money by increasing your energy bills. The Telegraph has more information on how to make a home energy-efficient, such as installing loft and cavity wall insulation and draught-proofing your windows and doors.

Explaining the scale

The current system for evaluating boiler efficiency is called the SEDBUK – seasonal efficiency of domestic boilers in the UK. A rating of A is the most efficient, while a rating of G is the least efficient. The SEDBUK rating is based on the theory that the most efficient boilers produce more heat using less fuel and generate fewer emissions.

In practical terms, a boiler with an A rating should waste only 10 per cent or less of the energy it consumes; however, a boiler with a G rating would probably waste at least 30 per cent of its energy. This means that for every £100 spent on energy for the boiler, around £30 of this is returning no benefit whatsoever.

Regular maintenance will help to ensure your boiler is operating efficiently. If you need Gloucester boiler servicing, contact a local company such as http://www.hprservicesltd.com/gloucester-boilers/boiler-servicing-gloucester/. An expert will be able to tell you more about what your boiler may need and how better efficiency can be achieved.

It is up to all of us to use energy more sensibly and not waste it. An efficient boiler is not only good for the planet and the environment but will also save you money. If your boiler has a G rating, it may be time to think seriously about getting a new one.
