Abstract: . . .  between 0.5-1.5 m2/person (small individual installation) and 0.30.5 m2/person (installation serving more than 100 people). B - Volume of the water-heater: volumes are given according to the surface of the sensors and the availability of auxiliary energy (conventional energy source). The volume of the solar-fired heater varies between 100 l/person (small installation) and 60 l/person (large installation). C - Note: in case of important sunning (summer) and reduced consumption (holidays) could appear a risk of overheating in the sensors which could cause the vaporization of the liquid (thermal fluid), . . .

C - Note: in case of important sunning (summer) and reduced consumption (holidays) could appear a risk of overheating in the sensors which could cause the vaporization of the liquid (thermal fluid), which imposes technical care at the time of design -the installation of a safety valve prevents any danger-. This technology is primarily used to produce domestic hot water but can also concern certain professional sectors, such as the laundries, using hot water for their activities. . . .
