Скачать или смотреть They Laughed When He Built a Second Chimney on His Stove Pipe — Until It Stayed 42º Warmer All Night

Frontier stove heating, thermal mass chimneys, off-grid cabin warmth, historical survival engineering — this documentary explores a forgotten 19th-century heating modification that neighbors mocked as pointless: a second chimney integrated into a stove pipe system.

In the winter of the American frontier, one builder quietly applied an old principle of thermal mass and heat retention — extending the flue path so hot exhaust gases transferred their energy into stone before escaping outdoors. While others burned through wood all night, his cabin stayed 42°F warmer until morning, using less fuel and holding heat long after the fire died.

This film reconstructs how the system worked using period-accurate materials, plausible measurements, and known heat-transfer principles — conduction, convection, and radiant storage — without myths or miracles. Drawing on local records, oral testimony, and vernacular building traditions, we examine why experts dismissed the idea, how extreme cold exposed the flaw in conventional fireplaces, and why this “ridiculous” second chimney quietly changed how frontier cabins were heated.

This is not modern HVAC.
This is old knowledge, tested under deadly cold, where efficiency meant survival.

Educational and historical reconstruction only — not a substitute for modern building codes or engineering standards.
