Community and Q&A

I am looking at a project that has some sort of electric radiant heating element embedded into the ceiling plaster.

It’s a 1 story house. Early sixties system that is still being used as only heat source. Strange arrangement.

The client wants to add ceiling lighting. Would anyone be familiar with the type of elements that were used to embed in plaster in the 60’s?

I would like to learn about it before getting my electrician involved.

    I think it is just some type of resistance cable, they also used it in sand beds beneath concrete floors as an off peak storage scheme. The cable as I recall had a red vinyl jacket. The gizmo the electricians use to locate hot wires might work in finding the ceiling cables beneath the plaster.
