We recommend Vaillant, the leading manufacturer of high efficiency condensing boilers. The Vaillant Group is an international family-owned company with a tradition of more than 135 years. In its core business of heating technology the company is the second-largest European manufacturer in this branch.
By recovering and using heat that would otherwise be lost up the flue, the best high efficiency boilers can operate with seasonal efficiencies in excess of 90%. Although high efficiency boilers require a higher initial investment, they are very economical, and can repay the extra initial cost in fuel savings.
If your existing boiler is more than 15 years old, replacing it with a high efficiency boiler could save you as much as 35p in every £1 on the gas used for heating and hot water. We give extended 5 years warranty on eco tec plus boilers and 3 years on eco tec pro
