This Vaillant replacement diverter valve is compatible with ecoTEC VUW (condensing), ecoTEC VUI (condensing) and Guernsey/Jersey only (condensing) boilers. A directional water device in combi boilers, a diverter valve directs hot water into a heating system or a hot water system. This feature means that combis are able to provide both heating and hot water without the need for a storage cylinder.
