How Much Gas Does a Boiler Use Per Hour? | Viessmann

About 60 per cent of your total energy bill for the year is down to your boiler so upgrading to a more efficient model could save you some money. Most new gas boilers could be up to 95 per cent efficient but boilers that are over 10 years old could see up to a 30 per cent drop. Boilers have an efficiency system that provides them with a rating.
