I wonder if anyone can help with this? Having just turned the central
heating on for the winter, one of the radiators does not come on at
all. All the others are OK. The radiator is downstairs and does not
even get warm, yet all the ones upstairs are fine. The radiators are
linked to a combi boiler. Any ideas?
What kind of heat do you have, steam or hot water baseboard? If it's
the latter, you could have air in the line or the circulator for that
zone is not coming on.
If it's the former, you could have a bad air valve.
The radiators are filled with hot water from the combi boiler. I have
'bled' the radiator to let the air out and there's definately water in
there because some came out after all the air had been let out - it's
just not heating up.
