glow worm

[PGA]

I have a Glow worm swiftflow (approx 10 years old). We have have hot water but no central heating. Every morning the pressure is at zero, and I have to open the valve to let more water into the system. Hot water is permanently dripping from the drain in the back garden. The pilot light also goes out 2-3 times a weel. Is this normal?

no the prv is leaking and needs replacing

... and the pressure vessel probably needs recharging with air to hte right pressure. Do a search on "pressure vessel" .


" hot water but no central heating" is a diffrent , unconnected problem. Could be pcb, sensor(s) etc assuming the GO signal is getting to the boiler.
