I am about to embark on a project that involves replacing a window with french windows. Currently, there is a radiator below the window. The radiator pipes emerge from the solid concrete floor. I believe that I have two options. Either:
1) Excavate the floor sufficiently to cut the pipes just below the surface and cap off. For the replacement radiator (which will be to one side of the new french windows) run new pipework from the upstairs circuit down the wall. I can probably do this in the corner, and box the pipes in.
2) As 1 but connect to the existing flow and return and extend to the the new rad location. Cosmetically this will be the best option but I am concerned that the more that I have to excavate, the higher the probability of damaging the pipework.
Any advice or tips as to how best to go about this? What problems am I likely to encounter? I don not like at all the idea of buried copper pipe but you have to work with what is there. The house is late 1970s construction. I do have a decent SDS drill!
TIA, Dennis
