Glow-worm showing F.22 in Tipton? The heating system is low on water. How to read the gauge, top it up safely, and spot the signs of a leak.
Read the gauge when the system is cold. A figure well under one bar confirms the code. The label in the boiler gives the exact target for your model.
Glow-worm combis have a filling link or a built-in key under the boiler. Follow the manual, add water slowly, stop at the target, close it off fully and reset.
Bleeding lets water out as well as air. A drop in pressure afterwards is normal and one top-up fixes it.
Look for damp under radiator valves and drips from the copper pipe on the outside wall. A failing expansion vessel also causes repeated loss and needs an engineer.
No. The boiler has protected itself and nothing is burning. The emergency is a gas smell: get out, no switches, and phone 0800 111 999.
Water only leaves a sealed system through a leak or a relief valve. Finding which one early saves a ceiling or a floor.
Yes, and too much pressure makes the relief valve drip outside. Fill to the figure in the manual and no higher.
