Why not just hang the mount from the ceiling? You could use galvanized angle iron, conduit, or even pressure treated wood. No need to fasten directly to the stone.

What kind of stone?

Limestone?-Highly unlikely.

Slate/Fieldstone?- Drill out mortar and attach 2x4s to walls, w/bolts, expanding cement and washers. Attach heater to 2 x 4's.

Granite or other non-layerd rock?- drill into stone directly, follow above steps.

Probably the same way I attach electrical panels to stone basement walls... I don't. Hang a couple 2x4's from the joist(s) closest to the wall and screw a piece of 3/4" ply to those. You're basically hanging a little wall off the joists.

That only works for pipe. Superglue is the correct adhesive.

Pretty much what I said!

The obvious rout would be to drill holes in the stone, but that's sometimes easier said than done, & may not always be stable. Why is it necesary to mount directly to the stone?

Is the entire wall one piece of rock, or are there some joints?
