Radiators hot at top and cold at bottom

hquinn2batman · 30 Dec 2005

New radiator fitted in conservatory has been cooler at bottom since it was fitted. Trv fitted to feed/ normal valve on return. Microbore pipe. Has been checked with head off Trv. Plumber says it needs balanced and has been fiddling with every radiator in the house for months and now I have other rads with the same problem and the original rad is no different. Plumber says it is normal for radiators to be hotter at the top and I now think that he's fobbing me off.

Any ideas?

Some suggestions.

Blocked rad, system needs balancing, poor flow from microbore, pump is not powerful enough to circulate the water, valves not open enough.
