I have a gas boiler system. Recently, we were without heat for about a
week, while we were getting a new solenoid fitted to the filter on the
boiler. Since this was fixed however, when the heating is on, no heat
is getting to the downstairs radiators, while the upstairs radiators
When I turn off all the upstairs radiators, the downstairs radiators
heat up no problem, but will not heat when both upstairs and
downstairs are on simultanously.
I tried to bleed the downstairs radiators in case there were
airpockets, but water came out immediately, with no hissing air.
Any ideas? Before the heating was off for a week while the filter was
being fixed there were no problems.
Thanks in advance, David
