Went to see a job today - replacement of a Vulcan Continental floor mounted monster fitted in the middle of the house and using an asbestos flue linking to a flexible stainless liner in a central chimney. Propose to fit new boiler in adjacent garage on outside wall and divert pipework. Attached picture shows manifold for 10mm rad pipes.
There are 8 rads in the house, 3 upstairs rads are fed by the 15mm pipe branching off to the right above the pump and the 5 d/s rads are fed from the manifold. The 5 returns come back to the manifold too and the 22mm pipe on the left of the manifold goes back to the boiler. Haven't seen this type of manifold before - assume it is a 'pipe within a pipe' design. Is this right?
Also, the rads are old ones with both the feed and return 10mm connections on the same rad valve on one side of the rad. There is no valve on the other end. Is this done with an internal riser? Assume there is no way to balance the radiators in a system like this?
