The Full Glow-worm Service: What We Cover
When we service your Glow-worm boiler, we're not just ticking boxes. We strip down the combustion chamber, clean the heat exchanger, and inspect the burner. We check the condition of your diverter valve, which, especially after periods of inactivity, can be prone to sticking. We test the expansion vessel pressure and recharge it if necessary, as low pressure can lead to system issues. We also ensure all safety devices are functioning correctly, including pressure relief valves (PRVs).
