Ondol heating was common in Korean homes until the 1960s, by which time dedicated ondol installations were typically used to warm the main room of the house, burning a variety of ...
An ondol conducts heat evenly throughout the whole room, although the part of the room closest to the agungi is much warmer. Comparing the ondol with the Western radiator: the heat from the radiator rises towards the ceiling, but an ondol keeps both the floor and the air in the room warm.
A heating system is a mechanism for maintaining temperatures at an acceptable level; by using thermal energy within a home, office, or other dwelling. Typically, these systems are a crucial part of an HVAC (Heating, Ventilation, and Air Conditioning) system.

Underfloor heating and cooling is a form of central heating and cooling that achieves indoor climate control for thermal comfort using hydronic or electrical heating elements embedded in a floor. Heating is achieved by conduction, radiation and convection. Use of underfloor heating dates back to the Neoglacial and Neolithic periods.
