Cost effective & energy efficient

The complete Vaillant boiler range is A-rated and operates at more than 90% efficiency, which means that more than 90p of every £1 you spend on fuel is effectively used to generate heat. In turn, G-rated boilers waste around 30p of every £1 you spend. What’s more, all Vaillant boilers are condensing boilers, which means that they recover heat from the exhaust gases that escape in the flue allowing you to cut down on carbon emissions and save money at the same time.
