Hi
Reasonably suddenly, a radiator in the (upstairs) bathroom and one in the (downstairs) dining room are not heating up. I have bled both.
All other radiators are working very well. I've tried turning some off to see if this would do anything, but no !!
Is there any other simplistic checks I can do to see why this is happening ?
(Combi boiler within one year new installed and system flushed etc at that time).
Many thanks.
Robin.
