Solar heating system with external
heat exchanger
Solar heating system with external heat exchanger
The control principle is the same as in a solar heating
system with just one tank, see chapter
.
The speed of the collector pump also controls the
adjustable temperature difference [Target collector
diff.] between the collector and the tank.

connected to buffer
In addition, a variable speed secondary pump is
available for the heat exchanger. Through speed
adjustment, it attempts to adapt the temperature
difference between collector and secondary flow (see
chart 78 °C - 74°C = 4 °C) to the temperature
difference between the return of the solar heating
system and the tank (49 °C - 45 °C = 4 °C).
Fig. 5-78: Regulation principle
In solar heating systems with external heat
exchangers, experience has shown that most of the
energy from the solar heating system goes to the tank
in this control principle.
