=======================================

For over five centuries, Alpine Europe heated its homes with a technology so efficient it nearly matched modern furnaces — using nothing but clay tiles and firewood. The Kachelofen, a massive ceramic stove built by guild-trained craftsmen called Hafner, could heat a room for twenty four hours on a single ninety minute fire. This video explores how it worked, why it was abandoned, and what it cost us to forget it.
