Vaillant ecoTEC Plus 618 LPG ErP System Boiler

Vaillant ecoTEC Plus 618 LPG ErP System Boiler


The Vaillant ecoTEC Plus 618 LPG System Boiler is built with premium quality components for market leading performance and reliability. This LPG System Boiler features a high efficiency pump for further reduced energy consumption.

System Boilers are filled directly from your mains water supply, usually meaning you won't require a cold water feed tank. The Vaillant 618 will need to be paired with an unvented cylinder to enable a plentiful supply of hot water. If you need some ideas or are specifically looking for a cylinder, why not check our range of Indirect Unvented Cylinders.

The standard warranty duration for the Vaillant Ecotec Plus 618 System Boiler is 5 years, however Vaillant are offering a 2 year extension to take the warranty to 7 years if installed and registered by a Vaillant Approved Installer. Please see our article for more information.
