I have an Andes kitchen stove without the water heating coil, does the loop get poured into the refractory, and is it bent or made from steel or stainless threaded pipe with fittings? Couple temps.room 92.5 cooktop 845° oven 325° outside 42°

This is an opinion - If you look into the fire box of any coal burner that's been running for a while you'll notice the fire bricks or refractory has a slight red glow (pretty hot). If water heating coils are imbedded in the refractory there will be a huge difference in temperature where the coils are, possibly causing failure of the bonding of the refractory material. I believe most add on water heating options are SS coils that reside in the open burining area of the device.

Does anyone have one of these coils or know of someone that makes them? Thank You!

I would agree with that statement. They wouldn't work very well embedded in the refractory as its an insulating material. Most coils are in or around the firepot/box or layed up against it.
