Chasing water pipes into wall - opinions

In the past I've had 15mm heating pipes sank about 2mm below plaster work, it took about 10yrs before it cracked the plaster, you could follow the pipe run up the wall with your hand it was so hot.

The 15mm pipe will be about 4/5mm below the finished plaster work, so no probs.

That would be a problem in my view - it is barely deeper than the depth a drawing pin could penetrate.

If we are talking about a hot water supply pipe - as per the OP's case - then given the issues with rising energy costs, heating up the wall every time you turn on the kitchen hot tap isn't the wisest use of energy.

Of course it is possible to chase in a hot water pipe with no insulation and the barest minimum plaster cover, the question is whether it is a good idea to do so.

Well I don't care about any of those issues

Yup. Gypsum plaster (e.g. MultiFinish) will crack and flake if exposed to temperatures over 50°C.

Understood.

Others might care though.
