Radiator pipes in the walls

evilgoose

Hello - I'm going to ask the regular question -

I want to chase the heating pipes into the wall as I've knocked off all the plaster.
(currently and for the forseable future there wont be any heating system)

I was going to run either 20 or 25mm coduit into the wall, ready to take the pipes (which can be fed down from the room above).

Which would be best for 15mm copper pipe?

Also,

what would be the best method to terminate the conduit?
I wondered if could run the two conduits into a 35mm single electrical back box?

thanks

How do you plan to install the pipes, why not use plastic pipe would be better than copper in my opinion.

The upstairs and downstairs walls are offset, if I lift a floorboard upstairs I can feed the pipe down into the conduit.

There are still some of the old copper pipes from the previous solid fule system under the floor, I was going (well by I, I mean get a plumber) to link them up

Think you will find it hard to put copper in after and how would you clip them. It may be better to fit the pipes in while it's open and then you can clip them, I would fit plastic pipes if it was my house.

When I built my house I used electrical trunking chopped into the wall to conceal the microbore pipes, which all came down from above. I arranged the depth, such that the trunking, when capped was just below the skim level. The final skim then covered the trunking covers very neatly. If access was ever required it would be a simple matter to break out the trunking cover and simple to replace and skim again. Access has never been required in over 30 years. As a system that I designed and installed myself, it has been a great success.

You would be better off installing plastic coated copper or conduit for plastic barrier pipe and be done with it.

Will the joint in the subfloor be accessable?

If you're redocrating with a view to a later CH install buy extra wallpaper!

Plastic is fine just as long as there aren't any pushfit connectors buried in the wall.

This would be best in my opinion.
