Viessmann - Boiler Efficiency Ratings

Boiler Efficiency Rating

You can find out the energy efficiency of your boiler by checking its energy rating; you can do this now by selecting the make and model below.

A boiler’s energy rating is an indicator of its efficiency when used within an average domestic household. It's a great benchmark for comparing new boilers and can help you work out how much money you could save on energy bills if you replaced your current boiler with a more efficient model.

For new boiler installations call British Gas Boilers on 0800 327 7119 for a no-obligation quote. Alternatively visit Boiler Guide to request quotes from independent local and regional heating engineers.
