This Vaillant pump is compatible with ecoTEC VU (condensing), ecoTEC VUW (condensing) and Guernsey/Jersey only (condensing) boilers. The pump moves heated water around a boiler, via the heat exchangers and into the radiators or hot taps. The pump is normally located before the diverter valve in a combi to allow circulation through a heating and hot water system.
