热水器的程序包括资料。本设计以AT89C51单片机为核心，可以使热水器在绝大部分时间内都处于“有热水”的状态。即自动加热、自动加水。当水位低于一定水位的时候，自动加水功能启动。当水温低于设定水温时，自动加热功能开启。此外本设计还可实时监视水箱内水温和水位。

-The program includes information on water heaters. The design of the AT89C51 microcontroller as the core design of a home water heater for the control circuit, using a wide range of low cost, high safety factor. Can make the water heater most of the time are in " hot water"　state. Automatically heating, automatic watering. When the water level falls below a certain level when the automatic water feature starts. When the water temperature drops below the set temperature, the automatic heating function is turned on. In addition, this design can also be real-time monitoring of water temperature and water level inside the tank. Intuitive and accurate.
