Hi,
I'm wondering if anyone has any idea what is going on with my boiler. A number of strange things have been happening with it.
A few nights ago I came out of the shower (water heats from boiler) and noticed the central heating had turned on. I checked the thermostat and was switched right down, so it should never have switched on. I noticed the pressure was creeping up to 3 to 4 bar. I de-pressurised the system back down to 1.5 bar, and it was still creeping up even when the boiler was turned off. I worked out that the filling loop ball valve, which is used to let water into the system to pressurise it, was leaking. So, I replaced that and it solved the pressure creeping up. However, the boiler is not working properly. When I turn on the hot water tap the boiler fires up and intermittently makes a clicking noise. I switch off the hot water but the boiler stays on and still heats up the radiators. If the pressure hadn't went so high I would have thought it was the diverter valve. However, it would suggest that the high pressure in the system has done something to the boiler. What do you think the problem is? Any tips on what to check?
I'm worried that the high pressure has done some serious damage to the system. Can that water pressure (4 bar), for a sustained amount of time (I'm thinking it's been like that for several days), cause leaks to happen?
Cheers.
