Had a look around the many posts on radiator balancing but didn't see an answer to this question, so....
How often should you need to balance radiators?
Reason I ask is this - had system powerflushed and balanced Jan 2009. For the rest of that winter all rads lovely and hot. Winter 2009/2010 rads lovely and hot again. This winter just gone, the rad at the end of the system gone back to being tepid (would get up to warm if heating on for a few hours and no hot water on; otherwise wouldn't get beyond tepid).
All other rads OK (got one that maybe takes a few minutes longer to get up to heat but otherwise OK).
The tempertaure seems pretty even over the rad once it gets up to the heat it seems to want to go to so no obvious signs of air (bleeds OK) or sludge.
This rad was cold/tepid prior to the flush & balance so is obviously the problem one in the system.
Should I expect to need things balancing again so soon?
Thanks,
Martino
