Boxing in - wiring and heating

[Diggory]

I’m renovating an old bungalow; fitting new rads and new/additional mains sockets to rooms.
Is it okay from regs / good practice point of view; to box in 15mm copper heating pipes and my wiring (for new sockets) in same box.
I’d planning to add the (dry lining type) socket into the same box - I’m trying to avoid lots of chasing out cable runs.

Thanks D

Yes, but you should avoid the pipes and cables touching each other.

Thanks reply.
So if ran a section of conduit inside the box and routed it as far from pipes as box would allow; would that suffice for separation.

ideally, put some pipe wrap on the pipes, or run the cable in conduit.

Be aware that putting the cable in conduit may alter its current carrying capacity; size it and/or the breaker accordingly

I think I understand (cable heat dissipation ?); is that a more theoretical consideration. Is 2.5mm^2 cable in a 25mm conduit any worse than under a galvanised channel buried in a wall chase ?

Thanks D

It’s a different installation method. Easier to insulate the pipes.

Yes. It doesn't have the wall on one side.

Yes. It doesn't have the wall on one side.

and the wall isn't hot

Yes. It doesn't have the wall on one side.

Thanks - that never occurred to me; so it uses the wall as a heat sink.

I’ll insulate the pipes as suggested and bin the conduit idea. I might partition the boxing - aiming to keep the pipes and insulation one side / wires the other.

Thanks D

Just looking at an older post where someone was asking advice for boxing in pipes in garage and the advice suggested a double skin box (because of Reg’s or control) - is this only because it’s a garage.

Yes, actually buried in the wall with mortar/cement is best.
