Thermosyphon systems operate on the difference in density between hot and cold water. They, therefore, require no circulation pumps and additional control loops.

Two systems differentiated by an optional continuous flow heater for auxiliary heating are available for calculation purposes.

Under System Definition, you can enter the type of collector, the continuous flow heater (fuel and power), and DHW consumption.

In contrast to other systems, the parameters for the tank are predefined. Circulation is not possible.
