Abstract：The intelligente control of water temperature for gas water heater is discussed. The disadvantages is covered which is control for water temperature at the present time. The heating time is cut down through using the method of fast enable in large firepower. Methods of temperature feedback and advanced control are used in order that the stabilization time for water can be shorted and the overshoot temperature is littie. The methods are used that safeguards, life length equalization and control for stable burn. Very-High-Speed Integrated Circuit Hardware Descrip- tion Language, VHDL, is used to describe the circuit’s function. Simulation through tools about electronic design automation is successed,and the simulation waves of the system are provided．
