I have a 10mm micro bore central heating system with manifold. I have added 2 extra radiators by teeing into an existing radiator as manifold is full. New radiators are luke warm and existing teed radiator is luke warm.
My next thought is to install another manifold piggy back style(No room to put bigger manifold in). Then pipe from the new manifold to the 2 new radiators.
Having spoken to 3 plumbing suppliers, the best I got from one was I needed a Wednesbury manifold which is not made any more.
So two questions:-
1. Am I doing the right thing?
2. Where can I buy a manfold to bo this job?
PS Existing manifold is 28mm in/out with 10mm out/return pipes from/to radiastors.
hi simply if you have run another 2 rads from an existing rad with 10mm pipework there is not enough bore for the water to circulate to all 3 rads put in this way its very easy to understand
the radiators are not receiving enough water flow to heat the radiators sufficently and they are also taking heat away from the primary rad from which they are taken
the best way to run the 2 new rads is go to the manifold and add a T peice before the manifold so you have a pipe which branches off into 2 then add another 28mm/4x10mm manifold which will accomodate the 2 new radiators
