Replacing radiator in my loft conversion
Options
Comments
-
I've already bled all radiators and rebalanced the system several times. The only combination that works is the current one, with most radiators valves barely open at the first two floors and the valves fully open in thr loft.
I don't know what are the temperatures.
I've returned the reader because it proved to be completely unreliable.
Both valves are two plain lockshield type.
The inlet water pipe is actually very hot, as hot as all the others (abd much hotter tham the rad surface). I don't understand how the radiator that irradiates heat very well doesn't get as hot as I expect, though.0 -

60 degrees.
I'm not aiming at anything specific because I did all the balancing without measuring anything. Only at my heart's content:-)0 -

Only at my heart's content:-)OK, a 60°C flow means you should be aiming for a 12°C drop across the radiator - To do this with any degree of success requires the use of a clip on thermometer (or better still, a pair). Doing by ear or feel is doomed to failure.A couple of cheap thermometer modules from Amazon or Ebay - They do not need to be accurate.

This is the case for any radiator - its temperature is a result of balance between supply and dissipation of energy. Cut the supply and the radiator will cool down to room temperature.0 -
Is it possible it's not bi-directional and flow and return are the wrong way round, if it has a baffle.0
