Forced Circulation System – Drainback With One Coil
Non- operating state of the system:
The entire heat transfer medium is in the Drainback tank during the state of rest. The collectors are empty.
Solar System in operation:
The system will start up automatically in sunlight and the entire cycle will be filled.
The pump will be turned off automatically when the final temperature is reached and the temperature is reached and the tank is completely heated. The heat transfer medium flows back from the collectors into the Drainback tank without evaporation. Overheating of the storage tank and the solar thermal system will thus be excluded.
