The templates consists of various configurations of solar combined with a boiler.
Solar & Boiler - Parallel
...
Working principle
The solar collector will capture the energy of the son, when the temperature inside the solar collector is higher than 65°C and higher than the bottom temperature of the storage tank, the heat from the solar collector will be transferred to the storage tank by activating the pump. The pump is deactivated when the bottom temperature of the storage tank is higher than the collector temperature.

More information on boilers can be found in Condensing boiler.
Notices/Remarks
If the user changes the power of the end-units, the thermal capacity of the solar collector doesn’t change automatically. The user should implement a correct capacity corresponded with the thermal power. The same goes for the boiler.
The capacity can be calculated by clicking on the pencil icon on the right side of the capacity. A pop-up window will appear in which the user can enter data from the technical specifications to calculate the capacitance.
The user should also implement the solar collector area and the thermal losses to simulate accurately. These parameters can also be found in the technical specifications of the solar collector.
The user can change the design temperatures, thermal power, end units, … But keep in mind that the controls have to be changed as well. This can be done by changing the setpoint values.
Solar & Boiler - Switchable serial in supply
...
Idem as the template “Solar & Boiler - Parallel”, except for the serial configuration instead of the parallel configuration. There is also a bypass valve to bypass the boiler when the boiler is deactivated.
