Worcester 8716118443 Boiler Fan Replacement

This replacement fan is a genuine Worcester Bosch spare for use in Greenstar, Greenstar ErP and CDi Series boilers. The fan introduces fresh air into a boiler's combustion chamber, ensuring that gas is burnt correctly and extracting burnt gas at the end of the combustion process. Your boiler's safety parameters ensure that no gas passes through to the main burner if the fan is not functioning correctly.
