Hello,
I wonder if you could help me. (sorry if this is in the wrong place, i'm new to the forum)
I've got some issues where i'm not getting hot water or central heating.
This has come ever since I drained the heating system (open vented with 2 tanks in the loft) down to fix a leaking rad.
I beleive i might have an airlock in the system ( when refilling i made the mistake of bleeding the upstairs rads first).
I've tried draining the system again and refilling (this time bleeding from the bottom) but still no joy.
The boiler (Glowworm Micron 50ff) is firing for about 5 mintues then cuts out, at this point i get large amount of banging noise from the airing cupboard.
Looking inthe airing cupbaord it looks as though i'm not getitng hotwater to the cylinder. The pipes going into the pump are very hot but the other side are warm (ish).
I've bleed the pump, i think (i've released a lot of air out of it), but this doesn't seem to have resolved any thing.
It looks like it could be a new pump needed but it was working fine prior to draining so i'm hoping it's not now needed.
If it's an air lock how can i clear it? drain it again? Backblast the system from mains cold?
I've done a fair amount of reading online and have familiarised myself with things (still only a DIYer) but i'm really getting stuck now and the wife will go mad if the weather turns and the kids haven't got heating.
Many thanks Richard
