Is anybody here old enough to remember electric heat sheetrock? We had one particular contractor that put it in all of his houses. The sheets had a
"pigtail" that you pitched up over the ceiling joists and the electrician wired
them later. All of the heat was in the ceiling. They had full heat sheets, half heat sheets, and 1/3 heat sheets. You received a plan on which sheets went where. The remainder of sheets were 5/8 firecode. (typical houses in those days were all 1/2" regular walls and ceilings) It was a really clean even radiant heat. Only drawback was you still had to put in an air conditioning system. Sheets were marked so you didn't nail thru the wires. Just Curious

Sure, I remember. It was called PAN-ELECTRIC made by Gold Bond. Gold Bond sold that division to a co. here in Ky. in the early 80s. Not sure if they are still in business.

I understood that it was extremely reliable. My uncle's house house had it and for 35 years I know they didn't have any problems with it. You had a different thermostat for
each room. It also was a very even heat. We had a separate price for the ceiling board
since it did take more time. Back then a normal house was all 1/2" thick 12' length board. There wasn't 6 different types and lengths of board in a house. The average house was a FHA house with 90 or so sheets. Everything was 8' and nothing wrapped. Everything was nail on. Occasionally it would be glued.

Hot rock lives!

I just purchased a home with a mystery power drain. Upon checking the beaker box discovered beaker labeled "hot rock.". This is what led me to find out I have an electric heater in my Sheetrock. This was a foreclosed home so I had no idea, I had electric heat until I got my electric bill. Ouch!!!

Does anyone know exactly what it is really called? Who makes it? What are the dangers if you accidentally drill into it? Actually any info would be helpful.

Is it still in working condition or is it just a power drain.

It still lives!

Yes,it works we had it turned on accidentally, we thought the thermostat went with the propane heater. Not knowing it was in the ceiling we drilled two holes to hang a light. Oops still working but how do we determine if it is damaged now? How do we figure out where the wire grid is located? Now that we know it is there, we may want to use it. This is on open ceiling without an attic, so we can,t see how it is attached to power. We also would like to hang speakers for our home theater system, so this could pose problem.

Easiest solution I can think of is to turn it on, let it heat up, and then feel the board. I would imagine that where the elements are would be warmer than the rest of the ceiling. Can you hang the speakers from the wall instead?

Yeah, I remember it from back in the early 80's. You don't see it any more because nobody can afford to heat with electric today and it's a major PITA to cut holes in it if you are adding lights for instance. There were lines printed on it to tell you where to screw or cut holes but all that is gone once it's painted. A lot of guys didn't even know it was being used and there is no easy way to tell. If the heat wire in the board is cut the rest of the sheet won't heat and there is no way to repair it. The whole sheet must be replaced.

Around here it's cheaper to heat with electricity than it is to heat with fuel oil

I've dealt with the hot rock. The element is a continous loop (of course) and are spaced about 1 1/2" -2" apart. On older paint jobs you can see the path of the element because the paint gets discolored from the heat.
Good luck.

I switched over to electric heat pump and backup air handler 5 years ago. My heat bills are lots cheaper than the guys buying the lp and natural gas.

The problems with heat pumps are the up front cost is high, and in my neck of the woods they don't produce enough heat in the winter by themselves, they need some sort of supplemental heat. What you use is up to you. Some use an electric coil, some use a gas or oil burner.

I want to put one in my place, but I can't swallow the $15,000 I was quoted.:censored:
