The Middle Ages are rightly regarded as miserable, because people did not have amazing HVAC products like a Goodman GMS8 Series Single-Stage Gas Furnace! Instead of a dual-diameter tubular heat exchanger, they had to throw another log on the fire whenever they wanted to get warm. Everybody smelled like smoke, and it was always drafty. The GMS8 has a lifetime warranty for the heat exchanger. I bet you can't even get a warranty on wood.
