Why Did Russians Sleep on Top of a Stove at −40°C?

A family in rural Russia. Outside minus 40. Inside, warm and comfortable, some of them asleep on top of the stove. Not metaphorically. On the actual stove. The Russian pech weighed around two tonnes of brick. You lit it once or twice a day, a hot fast fire for an hour or two. Then the fire went out. But two tonnes of brick holds an enormous amount of heat and releases it slowly, radiating gentle steady warmth for the rest of the day and through the night. A thermal battery charged by a short fire and discharging for hours. The smoke didn't escape straight up either. It was routed through a winding labyrinth of passages inside the brick, pressing heat out of the gases before they left. Almost nothing wasted. The surface stayed warm but never dangerous, a mellow radiant heat like a sun-baked stone. So they built a sleeping platform into the top. The warmest bed in Russia, claimed by the elderly, the children, and the sick. One structure. Kitchen, furnace, dryer, bathhouse, and bed. All from one firing a day. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ SOURCES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ THERMAL MASS IN MASONRY HEATING SYSTEMS Bainbridge, D.A. (2007).
