I used to have a small greenhouse here and I heated my house with wood. Every night just before turning in I would fill a coal scuttle with hot coals from the wood stove and set it in the greenhouse. I had an electric heater for backup but I don’t think it ever came on, the bucket of coals would heat the eight by ten foot greenhouse enough without any other heat. The coals would still be hot the next morning, a layer of ash formed over the top but down in the center would be red coals still.
