was using the shower earlier and the temperature kept changing. Checked the pressure gauge on boiler and it read zero, opened the top up valve and could hear water flowing in, after a minute or so the flow seemed to stop but the pressure is still zero.
I'm getting hot water at an even temperature now.
Central heating has been turned off at the wall thermostat for weeks.
No obvious drips from the overflow outside
Any ideas of what to check before I have to call a heating engineer?
Thanks
