ECOSTOR2™ SC SOLAR INDIRECT SYSTEM SINGLE COIL GAS BACKUP MODELS (CLOSED LOOP)

This intelligent design utilizes a low NOx gas burner as a backup when periods of supplied solar energy do not meet the required domestic hot water demand. To activate the burner, a thermistor temperature sensor is located in the upper portion of the tank to promote greater solar operation efficiency. A double wall heat exchanger is located in the lower portion of the tank to optimize solar heating performance and to provide additional protection between the surrounding water and solar heating fluid. Also, a draft diverter is utilized, providing an easy replacement for existing atmospheric vent water heaters.
