Vaillant System Boiler

System boilers are often referred to as sealed system boilers, providing central heating and hot water via a storage cylinder which is often housed in an airing cupboard. There is no need for water tanks in the loft, as with an open vent boiler. System boilers can be used with a hot water storage cylinder as a standalone heating system, or can be used as part of a number of renewable heating systems for example solar thermal. The ecoTEC plus range of system boilers is available in a range of heating outputs meaning there is a model suitable for almost every home looking to install this type of heating system.
