The point about pipes in concrete is a valid one. I have a customer with a 70's house. The heating pipes under the ground floor screed have pinholed somewhere under the hallway and the water tracked back about 20ft to the boiler in the kitchen.
The pipes had been lagged with 'hairfelt', but in some places the concrete was in direct contact with the pipes. I think now is the time (30years ish) that this type of installation will start to fail so we will see more of these jobs.
Anyway, its going to cost over £2k to make it all drop feeds and replace downstairs rads. I know someone is now going to say you can get a combi and 7 rads for that
