Glow-worm Boiler Installation in Orpington – Replacing an Obsolete System

The homeowners in Orpington contacted us regarding their aging Glow-worm boiler, which had begun to display persistent ignition faults and significant pressure loss. Upon our arrival, our Gas Safe engineer conducted a thorough inspection of the unit and its internal components. We discovered that the primary heat exchanger had developed a hairline fracture, causing constant water leakage within the sealed system. Furthermore, the printed circuit board was showing signs of heat fatigue, leading to intermittent electronic failure. Due to the age of the unit, spare parts for this specific model have become obsolete, making a repair impossible. The constant cycling and pressure drops were preventing the heating system from reaching the desired temperature, resulting in cold radiators and unreliable hot water. After discussing the technical findings with the customer, it was clear that the boiler was beyond economic repair and posed potential safety risks if left in its current degraded condition.

We recommended a modern Glow-worm Energy high-efficiency boiler as the ideal replacement to ensure compatibility and reliability. Our team began by safely isolating the gas and water supplies before draining down the existing system. We removed the old, faulty unit and performed a comprehensive chemical power flush on the radiator pipework to clear years of accumulated sludge and debris. This step is crucial to protect the lifespan of the new installation and maximize heat transfer efficiency throughout the home. Once the system was clean, our engineers installed the new Glow-worm boiler, fitting a new magnetic filter to capture any future magnetite particles. We meticulously checked all flue connections to ensure they met current building regulations and carried out a full gas pressure test to guarantee system tightness. After purging the system of air and balancing the radiators, we completed a combustion performance analysis to ensure the burner was operating at the manufacturer's precise CO2 levels for optimal energy consumption.
