How do I put rad pipes in a wall chase please?

[scotster]

I need to chase rad pipes into a 100mm thick breeze wall as my SO. would like one of the fancy rads, and would like the full 'hotel look' with pipes coming from the wall.

The pipes have to travel up behind skirting and up about 8" behind plaster.

What's the best way to do that please to avoid any issues in the future? Wall will be skimmed and painted. I assume I need some king of boxing or insulation around the pipes to allow for expansion/heat.

Thanks for your help!

Rgds, Scott.

according to the rules, a pipe can be raggled into a wall and plastered in without building any pipe chases prividing you would be able to cap the pipe if there was ever any problems. as far as the type of pipe, im not sure, mabe plastic. im sure i read somwhere that copper reacts with cement/plaster etc ??

hope your charging accordingly.

any comments.

Any pipe needs space to move, and be insulated or it'll crack plaster.
Anything fitting other than a soldered copper joint needs access.

Thanks for the inpu tGents.

Since posting that I found your helpful response on a similar question where you advised gluing some thin lagging around the pipe and try to avoid any joints by using a pipe bender if possible.

I also saw the method using the flexi conduit from screwfix but at £20 a roll and I only need 16" I may just go with your idea!

Could I use some plastic cable trunking that I have instead? Only difference is that it is smooth and ridged - you know the type of stuff you use for trunking in cables around garages etc? Only advantage I see of doing this is that it isolates the pipe completely and allows you to remove (you would still have to chop out/cut the 90 degree bend however) in case of a leak. It means a much bigger chop into the wall though!

Thanks again. Rgds, Scott.
