with standby tank
Description of hydraulic configuration:
The collector array heats the buffer tank. If the temperature level in the buffer tank is high enough
to heat up the lower part of the dual coil DHW standby tank, the discharge pump of the buffer tank
(primary loop) and the loading pump of the DHW standby tank (secondary loop) are started up.
Consequently, the solar energy from the buffer tank is delivered to the DHW standby tank via the
external heat exchanger. If the temperature in the upper part of the standby tank is not higher
than its desired temperature, the tank is heated to the desired temperature by the auxiliary
heating.
The system consists of the following components:
•
Collector loop connection, contains
