Please help.
My rads are cold on bottom and warm/hot on top.
13 rads in total 11 new 2 older ones, I put in Heating myself with Worcester LPG boiler 95k btu and have 3 port valve and pump. Stat's etc..
HW only is fine, CH only rads get really hot but not as hot as I think they should get. When HW& CH are on rads stay warm only.
I am pretty sure I do not have any sludge in system as I have flushed out old rads when I re installed them..
Thanks in advance for any help.[/b]
