Hi
I'm having problems with only one of my downstairs rads getting hot when system comes on in the morning. Gas board under service contract came and said I needed a powerflush (not covered....there's a surprise) , had it done by local plumber (£200 cheaper) he didn't find an awful lot of sludge, put system back on and all fine but this morning problem has returned.
System (hot water and heating ) set to come on in the morning until 10:00 although hot water and upstairs rads fine the rads downstairs except 1 are cold. If I switch heating back on after the 10: 00 they all come on lovely and hot!!!
Gas board are coming back but not got a lot of faith in them, anybody got any ideas please that I can throw at them
TIA
Hodge (so far £400 for possibly un-needed powerflush lighter)
