I converted a decorative wood-burning stove to a propane burner inside to radiate heat in all directions
The propane heater is about 25,000 BTU and is really hot burning. It should be tuned up better than it is for easy, lighting, and burning. Or an electric heater could be inserted instead of the propane burner it’s on wheels and real cute the teapot on top rest on a movable duct to aim heat flow.
