Abstract—The present paper deals with a simulation based on the ISIS-PROTEUS software to design a solar heater of water control system by using the PIC 16F877 microcontroller based on the PROTON programming language. The reserves of oil in different countries were been illustrated. A short demonstration of the worldwide potentiality in solar water heater has been focused with the actual needs of alternative economical strategies to heat the water. A general principle of the solar water heater and its parts was presented to describe the real plant. The simulation was been realized by using ISIS-PROTEUS software and the results have been carried out using a digital LCD which displays the hot water temperature. This temperature varies between the minimal value 20oC and its maximal value 70oC. The results prove petitiveness of the solar technology with the performances of the simulation of the solar water heater control system which can be tested soon in real time by developing the analyzed study as an electronic circuit connected to a solar water heater.
