Ive bought a house with all the radiators fed in 8mm off a manifold (Fed from the boiler, F + R, in 15mmCu )
Is this efficient enough to keep in? The runs to each radiator are only a few metres, and each leg off the manifold only feeds one radiator? I am told that upgrading to a bigger pipe would be more efficient, but is it neccesary - Can I still have a good system?
Also presuming I can, can I Tee off the 8mm to pick up another rad (Not enough ways on maifold), or would I be best 'T'ing off the 15mm feeding the manifold.
Would appreciate any help here, going round in circles haha - cheers.
