Hello uk.d-i-y world.
Yesterday, I thought I'd put the heating on... it being June and all.
There was a bit of gurgling from a radiator that usually gurgles, so I bled it and put a bit more water into the system - by turning a thing that is a bit like a washing machine tap. System came on and worked for a bit then it stopped working. I was puzzled but left it to this morning to have a closer look.
The boiler is a Worcester Bosch Greenstar CDi that was fitted last November. The plumbing (radiators etc.) are of an older (~90s) vintage.
The hot water is working fine.
This morning, before switching on, the system pressure gauge showed 0, and the display 72 (I guess degrees). I'm not sure what these numbers would normally be before switching on.
After I switched it on, the temperature quickly rose past 99 and then u1.. u9 (which I guess is not right). The radiators didn't come on. I bled a few and a little bit of air and distant gurgling occurred, but no actual water.
I'm about to call our service guy, but just to get an idea... Is this likely to be the boiler? or, more horribly, a pipework issue?
(The house is a bungalow, and I'm a bit worried that the pipework could be dumping water without us knowing).
Thanks for any ideas.
Bob.
