At my sons house, had 2 radiators downstairs that would never heat up, so thinking that the locks held valve was down, today we replaced the valves, but still got the same issue.
He has a glowworm ultracom cxi combi boiler, upstairs gets hot quite quickly, we have bled all radiators, and tried to balance the system, but to no avail.
He has a policy for boiler service and parts only. I think it is with utility warehouse.
Should he just call them out and see what they say, just call a local heating engineer out, or anything else that he should check first ?
