Yeah I've tried a reboot and all the valves are as they were prior to the water outage so it looks like I need to contact a boiler repairman tomorrow. I appreciate all the help and advice that you guys on here have given me in trying to sort my heating issue out.
From what I was told when we had this boiler fitted was that it's a fully pumped system and considering I don't have an issue with the domestic hot water hotness or pressure wise I would say that the pump is working as it should but like I said I'm not a heating engineer.
The boiler was working fine before the water outage and the only reason I topped the pressure up was because after it became apparent that the heating wasn't working I checked for air in the system, there was a bit say a hiss for 2 seconds and because it says in the operating instructions...
The only valves I've opened are black ones and they are the loop that allows you to increase the pressure, I did try to turn the blue valve on the for right as suggested but it won't budge and I've not touched it .
I'll have to get a heating engineer out tomorrow because I'm not and although I haven't touched anything apart from slightly increase the water pressure which I know how to do it's not been touched .
No mate still no heating, I haven't touched anything. All was good until our water supply was cut then got up this morning to a rather cold house yo find that the central heating is not working but we have DHW.
Someone I was initially talking to suggested that I post on the other one that I might get more answers and no I wasn't fumbling in the dark and going back to that return isolation valve I haven't touched it and without forcing it it doesn't turn .
