Hopefully, it will only be 4ft long to fit in a 8ft ceiling or less on a 2ft tall stove, while maintaining code distance from the ceiling as the pipe will 90deg out the wall.You’ll get a remarkable amount of heat off the pipe itself with that much vertical pipe surface.
They make many sizes. But you can bake small sheet pan or cake pan sizes in this one. About doubles the heat from pipe due to surface area.Do they make a toaster too? A slotted oven you insert slices in?
Probably would heat too slow to toast.
