Concrete floors and radiators

[jeeves]

Hi

I am installing radiators in the downstairs using a 15mm drop down flow/return from the 22mm flow/return.

Because the downstairs has concrete floors I am left with the problem of trying to conceal the pipes.

My 2 options are 1) cut a channel in the floor or 2) run the pipework behind the skirting (but that will make the piping more troublesome I think)

Is it ok to run the pipes to the radiator using a short length of 10mm from the 15mm? Or will this reduce the performance of the heating? My thinking is that this will be easier to route from behind the skirting?

Any ideas?

TIA

You will reduce the flow and it will be more hassle reducing down to 10 mm. Why not chase the plasterboard out behind the skirting.
