Identifying End-of-Life Parts on Older Worcester Boilers
Worcester Bosch has excellent parts support for their current Greenstar ranges, like the 2000, 4000, and 8000 Life. However, for the earlier Greenstar i and CDi series, we're increasingly encountering parts that are either discontinued or only available as refurbished units. Common culprits for wear on these older models include diverter valves on CDi variants, and the 3-way actuators becoming sticky. Pressure loss through tired filling loops is also a frequent call-out. We carry common Worcester diverter cartridges, PRVs, pumps, and expansion vessels in our van, but some specific components for the oldest boilers may require a search.
- Diverter valves (CDi models)
- 3-way actuators
- Filling loop components
