The Worcester Bosch 77190019960 HE Series cleaning set is a genuine OEM maintenance kit designed to support thorough and effective cleaning of heat exchangers and internal components in compatible Worcester Bosch Greenstar and CDi series boilers. Over time, combustion by-products, soot, limescale and debris can build up on heat exchanger surfaces and within flue paths, reducing thermal efficiency and potentially leading to elevated flue temperatures and poorer boiler performance. This cleaning set provides the specialist brushes and tools needed to remove deposits safely and restore effective heat transfer during servicing.

This cleaning set is compatible with selected Worcester Bosch Greenstar and CDi boilers that list part number 77190019960 for heat exchanger and service cleaning tasks. Because service requirements and component access can vary by model, output rating and production year, it’s recommended to confirm that the kit matches the maintenance procedures outlined for your specific boiler model and GC number before use.

Key features of the Worcester Bosch 77190019960 HE Series cleaning set include genuine Worcester Bosch manufacture for quality and correct tool specification, a selection of brushes and cleaning tools designed to reach heat exchanger plates, flue paths and other internal surfaces, support for restoring effective heat exchange and boiler efficiency, suitability for use during scheduled servicing by a qualified Gas Safe heating engineer, and dependable performance that helps prolong component life and maintain efficient, reliable heating system operation.
