FORCED CIRCULATION SYSTEMS OPERATION AND INSTALLATION
Forced circulation central solar systems are used for the production of hot water for domestic use. They are an
ecological proposal and an efficient energy solution, combining high efficiency, autonomy, design, ease of installation
and savings, as the cost for the consumption of conventional energy sources is significantly reduced.
OPERATION:
The system’s automations constantly monitor the temperature difference between the collectors and
the boiler and give the relevant orders to assure the constant supply of hot water according to the circuit settings.
The differential thermostat is electronically programmed to control the differential temperature and is provided with
communication keys and a screen on which the parameters and messages are displayed.
Systems can also be provided with:
y
Antifrost protection system for the closed loop.
y
Closed loop overheating protection system.
When the collector temperature exceeds the boiler temperature by 6-10°C, the solar system’s circulation pump is
activated (start differential temperature). The circulation pump will stop when the temperature difference is reduced
to 3-4°C (Hysterisis).
