Poor water quality is the number one cause of central heating system breakdowns.
This 18-year-old boiler was producing inadequate, tepid hot water and was beyond economical repair. Once removed, the cause was clear — heavy sludge contamination inside the plate heat exchanger and system, restricting performance and efficiency.
We replaced the existing appliance with a new Worcester Bosch 4000, complete with Worcester Bosch Professional controls and accessories, all backed by a 10 year guarantee for total peace of mind.
To ensure the new installation performs at its best, we carried out a full system cleanse using ThoroughFlush as standard, alongside the ADEY MagnaCleanse 2 and Vibra2 agitator. The system was flushed well, removing built-up sludge and debris to protect the new boiler and maximise efficiency.
The result? Reliable hot water and heating, improved performance, and complete confidence in a boiler installed the right way.
