The Worcester Greenstar CDI boiler service kit is a genuine OEM maintenance parts package specifically assembled to support routine servicing of Worcester Bosch Greenstar CDI series boilers. Designed to include the key consumable components most commonly replaced during a standard annual service, this kit helps ensure that your boiler continues to operate safely, efficiently, and reliably by refreshing worn seals, gaskets, and other service items that can degrade over time with normal use.

Compatible with Worcester Bosch Greenstar CDI boilers, this service kit typically contains parts such as seals, gaskets (including the primary and secondary seals), the diverter valve service components, and other vital service-related spares that are specified in the manufacturer’s service procedures for CDI models. Because the exact parts included can vary slightly by specific boiler model and output size, it’s recommended to confirm that the kit matches the requirements listed in your boiler’s service manual or GC number before use.

Key features of the Worcester Greenstar CDI boiler service kit include its genuine Worcester Bosch manufacture for assured quality and correct fit, comprehensive selection of replacement service parts targeted at annual maintenance, help in restoring effective sealing and hydraulic performance, support for maintaining boiler efficiency and reducing the risk of leaks or faults, and suitability for use by a qualified Gas Safe heating engineer during scheduled servicing.
