Glow-worm Boiler Service in Bromley – New Home Safety Check

The homeowners recently purchased a property in Bromley and wanted peace of mind regarding the existing central heating system. They contacted Heat Cover to conduct a professional service on their wall-mounted Glow-worm boiler, as the previous owners had not provided recent maintenance records. Upon our arrival, we noted that the unit had been neglected for some time, which is common in property transitions. During the initial visual inspection, our Gas Safe engineer observed signs of dust buildup within the combustion chamber and slight carbon tracking on the electrode leads. The customer was concerned about potential carbon monoxide risks and overall system efficiency, particularly with winter approaching. It was essential to perform a thorough strip-down service to ensure the flue integrity and combustion quality were up to current safety standards before the family relied on the system for their hot water and heating needs.

Our engineer began by performing a flue gas analysis using our calibrated analyser to check the combustion ratio and CO/CO2 levels. We dismantled the heat exchanger cover to inspect the burner assembly, carefully cleaning the burner ports and heat exchanger fins to remove debris that could lead to overheating. We then inspected the ignition probe and the flame rectification electrode, cleaning the contact points to ensure reliable ignition every time. After reassembling the unit with new seals to maintain airtight integrity, we performed a full pressure check on the expansion vessel and inspected the condensate trap for any blockages. Finally, we conducted a working pressure test on the gas supply to the boiler to ensure the appliance was receiving the correct gas rate at the meter. We verified that all safety devices, including the pressure relief valve and overheat thermostat, were functioning correctly, leaving the Glow-worm boiler operating at peak manufacturer specifications.
