A couple of downstairs rads are stone cold, couple upstairs only slightly warm, all the rest are piping hot.
When I turn off 3 or 4 of the hot rads, the problem rads all heat fine.
I've tried bleeding and have checked all the trv's and freed a couple of pins that were stuck but rads are still only slightly warm at best when all turned on.
Any suggestions, circulating pump perhaps?
