The heat transfer model of ondol heating system is derived in the linear form. The step responses of On-Off controller, PID controller and Position type fuzzy controllers are compared in the sense of several aspects : variation of temperature feedback variable, variation of supplied heat quantity by the boiler, variation of flow rate, variation of thickness of the base, variation of the outdoor temperature.

The heat distribution model of an ondol house is developed by heat flow equation. The heat distribution model is simulated by Simulink. Mixing valve control and pump speed control techniques are compared. The automatic adjustment of a supply temperature is suggested using the feedback of a return water temperature.
