This job required two visits due to the need for additional parts. The property was located near the Island Bohemian Bowls Club, a popular local landmark. The Worcester Greenstar CDI combination boiler had lost power, prompting my first visit.
After replacing the quick fuse, it quickly became apparent that the issue wasn’t so simple. The fault was traced to the malfunctioning pump, which unfortunately had to be specially ordered. After a few days, the pump was delivered, and the second visit was scheduled.
Second Visit: Pump Replacement and Boiler Restoration
During the second visit, I installed the new pump, and the Worcester Greenstar CDI boiler was up and running again, restoring heating and hot water to the home.
British Gas and the Aluminium Heat Exchanger Issue
An interesting detail that came up during this repair was the customer's previous experience with British Gas HomePlan. The customer had been a member but was informed that their boiler was no longer supported under the plan. British Gas reportedly cited the aluminium heat exchanger as the primary reason for this decision.
Aluminium heat exchangers, which are common in the Worcester Greenstar CDI models, can be more susceptible to corrosion over time, especially in areas with hard water. This could potentially affect the performance of the boiler, leading to unsupported claims from service providers.
For homeowners in Reading and nearby areas, it's essential to have a trusted local boiler technician who can handle everything from fuse replacements to complex parts like heat exchangers and pumps. A professional, local technician ensures a faster response time and proper care for your home heating system.
