Typical Glow Worm Problems

Losing pressure, a pump that hums but does not move water, a failed circuit board and a stuck diverter valve are the faults we see most on Glow worm boilers. Many are straightforward repairs, and the parts are still widely available for most models.

More Information

Repair or Replace

Glow worm boilers are built to a price, so the repair question comes up sooner than with some makes. If the board and the heat exchanger are both failing on an older unit, replacement usually works out better. We give you both figures free and let you decide.

Keeping Costs Down

An annual service, a magnetic filter and the right level of inhibitor do more for a Glow worm boiler than anything else. Most of the expensive failures we attend trace back to dirty system water. Clean water and a yearly check keep the running costs sensible.

Frequently Asked Questions

Can you still get parts for Glow worm boilers in Godalming?

For most models, yes. Pumps, boards, sensors and diverter valves are still widely available. Very old models can be harder, and where a part has been discontinued we will say so and price a replacement boiler instead rather than keep you waiting.

Why does my Glow worm boiler keep losing pressure?

Pressure that drops week after week means water is leaving the system. The usual causes are a small leak on the pipework, a failed expansion vessel or a pressure relief valve discharging outside. Repeated topping up hides it. We find the leak and repair it.

Do you service Glow worm boilers in Godalming?

Yes. An annual service on a Glow worm boiler checks combustion, pressure, seals and the safety controls, and includes cleaning where it is needed. It keeps the warranty valid on newer models and catches the small faults that would otherwise leave you cold in January.
