Glow-worm Boiler Installation in Chislehurst – System Upgrade

Our client in Chislehurst contacted us after experiencing recurring pressure drops and intermittent heating failure with their aging boiler. Upon arrival, our Gas Safe engineer performed a full diagnostic assessment and discovered that the secondary heat exchanger was severely blocked due to years of sludge accumulation. This fouling had caused the pump to strain significantly, leading to a burnt-out circulation impeller. Further inspection of the internal components revealed widespread corrosion on the burner assembly and degradation of the flue seals, posing a safety concern. Given the age of the unit and the lack of readily available spare parts for this specific legacy model, it was clear that a repair would be an inefficient use of resources. We advised the homeowner that replacing the unit was the most cost-effective solution to ensure long-term reliability and safety.

We recommended the installation of a high-efficiency Glow-worm Energy 30kW boiler to replace the redundant unit. Our team began by performing a thorough chemical power flush of the existing radiator system to remove magnetite and debris, ensuring the new boiler would operate at peak efficiency. We then installed the new unit, incorporating a magnetic system filter to protect the internal components from future debris buildup. Once the mechanical connections were secured, our engineer carefully checked the flue gas analysis to confirm optimal combustion levels. We pressure-tested the entire pipework network to ensure zero leaks, registered the installation with the local building authority, and provided the homeowner with a detailed handover. The system was balanced to ensure even heat distribution across every room in the house, providing a much more responsive and energy-efficient heating experience compared to the previous setup.
