Hi,
I have recently been having problems with my Glow Worm Betacom 30.
First off, it kept losing pressure from the PRV and now that has been replaced and is fine. It doesn't leak at cold pressure.
Now since installing the new PRV the boiler needs to have a pressure above 1.5 bar (cold) to fire up. Once the boiler and cental heating has warmed the pressure obviously now rises above 3bar, therefore dumping water out the PRV. This causes the problem as when the boiler cools again the pressure drops to around 1 bar and this isn't enough to fire it.
I must add, when the first PRV went faulty and kept making the boiler lose pressure i kept topping it up from the filling loop for two weeks before I took action to replace it.
Help and info would be much appreciated.
Thanks
Paul
