    Change the dogs legs to 15mm in the loft and run them in the corner of the room in trunking under the floor and up into the rad.

    I know, but it's all dropping down from the loft, might be happy to pay for chiselling in, I've not asked, and I've no idea how long that would take???

    Take ages even using a wall chaser. I have done that when piping to ordinary rads, but the lack of movement in the pipes to the rad valves is then a problem.

    What, with a machine?

    How much does a machine cost? And how many cutters will I go thru?

    Behind the skirting?

    That's what the customer mentioned, it's probably the best compromise, but pipes coming out of the skirting still looks a bit **** I think.

    Ffs, installing is hard!!!

    I wouldn’t do it. But it’s an option. I would chase the wall or floor. Wall is the easiest option.

    It depends on the size/surface area of the radiator and the delta T.

    They will govern the required water flow rate/speed/volume required.

    That will determine the size/bore of pipe required.

    There are other things to consider when designing a system such as frictional resistances through pipe work, pump sizes, water noise etc but I am presuming that all that is correct and you are just changing the radiators.

    I agree with other comments about the aesthetics.

    Those type of rads were not really seen (in real life), with 10 mm pipes sticking out of walls.

    Customers!!
    Fashion!!

    Pretty standard that mate. For me it’s decorative column rads.
