The cost of heating our homes can be as much as 60% of our energy bills, especially in the winter. This means when it comes to energy efficiency, the benefits start with saving money. And they start with the boiler that you have running your heating system.
The age and type of boiler that you have is a big factor in its efficiency. Older boilers may not be the current efficiency standards or may have deteriorated over time to mean they don’t work as well as they did when they were new. There could be some deterioration of the parts that means they have become less effective in their power use or the changing needs of the house may mean they are no longer quite the right type of boiler for the job.
Boiler energy efficiency is expressed in a percentage and since 2010, regulations mean that only boilers that are 88% or above in efficiency can be installed in homes. The most common way to rate a boiler is with the A-G system of the ErP energy labelling. The majority of modern boilers are A rated which is the top standard.
If you want to compare one boiler with another, the Sedbuk system can also give a more accurate picture than the ErP labels. Modern boilers should be Sedbuk 2009 and have a percentage against them. You can often find this figure in a manual or your boiler installer will be able to tell you what it is.
