In Korea, the temperature in winter sometimes drops to -20 degrees Celsius.
Traditional Korean houses have rather thin walls, mostly made of wood.
So how did they get through such cold winters? That's thanks to a very smart and very efficient underfloor heating system.
There are many heating systems also designed to add to cooking or cooking hot water for bathing. The underfloor heating system is typical of Korea. It dates back to prehistoric times, and so it is embedded in Korean folklore and traditions.
