Copper pipes in screed

[samgrove4]

I have some copper pipes (hot and cold feeds) that have been wrapped in denzo tape and then screeded over (no other sleeves or protection). Only a relatively small area close to where the cylinder will be based has been done so far.

Just wanted to check if:
(i) this is okay for this area
(ii) okay, but preferably should be done another way...
(iii) is likely to be a problem

Advice appreciated.
Thanks

will be ok if wrapped properly but not the best as regards pipe insulation

Wrapping looks pretty thorough and has so far only been screeded over a 3ft length.

This is not to Building Regs - it should be insulated in a duct with a removable cover.
