I'm looking for any information regarding electric heat installed in the ceiling in about 1975.

What kind of stuff was it? how was it likely installed in 1975? Was it a mat or a single wire looped back and forth? If it was more than one wire in parallel, how was it spliced? J-boxes? How efficient is it?
 
Ceiling heatwas a passing fad that didn't live very long. Basically it is set up the same way bathroom floor heat is done.

Heat rises so efficiency is not good nor could you ever cut a hole in that ceiling again with ruining the ceiling.

You would be better off with floor heat.
 
I stayed in a hotel up north that had it. The thermostat was just like a baseboard heater.
Their was 2 ft of snow out side and very cold. It stayed very warm inside.
I'll bet the electric bill was high though. Like Dennis said heat rises.

But for a hotel or motel I bet their was very little or no maintnace required to it.

Who, me?

It's basically made of drywall panels with a loop of wire imbedded in it, and it's important to not make holes in the panels for obvious reasons.

I've heard of attempts to splice the wire element if it's damaged, but I jave not had any first-hand experience with it, as I've never damaged any.

The heat is somewhat effective despite the room space being below the panels, because radiant heat does not 'rise' the way convective heat does.
