Garage heat

I highly endorse the 55 gal drum conversion. I had one in my shop, used twelve extra feet of stovepipe across the shop before exiting to the chimney. Three newspaper logs would burn for five hours and make is to hot I had to crack open two windows - - Oklahoma winter at 10 F degrees. The most amazing heater I had ever seen. And, the newspapers were free from three neighbors for the entire winter.
