This Vaillant insulation is designed to prevent the escape of heat from the burner of ecoMAX VU (condensing), ecoMAX VUW (condensing), ecoTEC VUW (condensing) and ecoTEC VU (condensing) boilers. The burner produces heat in a combustible heating appliance. In natural gas appliances gas is transferred to a gas valve and into the burner for ignition. The heat created is used to heat the water in the master heat exchanger. As the leading supplier of parts for all the major boiler manufacturers we’ve got a wealth of experience and knowledge in this area, and with over 450 branches we carry more heating spare parts in more places than any other merchant to help you improve your first time fix rate.
