radiator pipes

[333rocky333]

I often see Radiator pipes protrude through the floorboards and up into the valves, thus the pipes on show in front of the skirting.
However bathroom Towel Rails I have seen the pipes protrude from out the wall.

Is there a reason Radiators cannot be fitted the same as there is no skirting fitted yet.
Maybe too many bends restricting the flow?

Apart from aesphetics, i can then get all the Plumbing installed prior to the flooring and finally the skirtings.

As Plumbers Would you think its unreasonable to ask, obviously more time consuming, when i get the man round to quote.
Is there a Trade name for this type of install, I recall a bloke on telly naming the method years ago but forgot the name now.
Thanks in advance

Do it all the time... Did it yesterday... continuing today

"Out the wall feeds".
Do it in copper.
Wrap them in duct tape to protect from filling products.
Positioning is crucial (rad length plus 45mm each side; 1 inch above skirting)
Solder long street elbows on the ends, to pop straight up, into valves.
Use 3/4 union lockshields, to make future removal and fitting of rads easier, as pipes will be 2 fixed points.
Pop pushfit caps on before filling chases and soldering street elbows on and pressurise system to check for leaks.
