A Worcester Bosch replacement heat exchanger for Compact, Greenstar and Greenstar ErP boilers. The heat exchanger transfers heat from a boiler's burner to water. A primary heat exchanger is found in all boilers, using heat from a burner to raise the temperature of the water in the system while a secondary heat exchanger is present only in combis and allows the heat to be transferred between closed systems. 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.
