Balancing parallel rads

[michaels]

Gentlemen,

A simple one I hope . I have two radiators in my bedroom that are fed from a single spur from the main boiler flow-return loop. They are plumbed in parallel to one another, either side of a small dividing wall (two rooms knocked into one). I wish to balance the radiators but how do I proceed with these two? I know for a single radiator I am looking for a temperature drop of approximately 12C, but what about for two rads in parallel?

I tried a search and obviously got loads of hits on balancing but none about parallel rads.

Any help would be much appreciated.

Michael.

On all two-pipe systems, all the radiators are in parallel. In your case the individual branch pipes are very short, but the principle is exactly the same as for any other radiator.
