UFH pipes through cavity wall

[Super_Paulie]

in an effort to avoid congestion from the under stairs cupboard where my manifold is, i am looking at the option of passing a single loop flow and return through the original cavity wall from the extension. If i dont then i have all my loops going through a very small area at the start which seems troublesome.

 

Whats the best way to achieve this, core drill out at the correct level to pass conduit through the cavity? remove a brick each side, run conduit and then make good with mortar?
Its a joisted floor each side with the pipes running above the PIR and biscuit mix over.

Any thoughts welcome.

I've put UFH pipes through walls. Drill a hole large enough for some flexible conduit, make good with some motar....expanding foam.

I too ran pipes through walls for the same reason to stop congestion in doorways, drill hole and put short lengths of overflow pipe in then thread the UFH pipe through that, 👍

heres where i find out the floor levels are wildly different from old to new.
