A study with the TRNSYS software of solar water heater installations was simulated for the domestic hot water needs of an average family in the Mediterranean climate of the city of Oran in Algeria. Comparisons of systems with one tank and two tanks have shown similarities in the quantities of energy consumed and captured by the solar panels, but differences have been observed in the coverage of auxiliary energies. On the other hand, the two-tank system makes it possible to produce very significant temperature stratification.

Keywords: Solar fraction, solar water heater, tank, stratification, temperature.
