System scheme 3:

TERRA heat pump with IDM-Hygienik and extra
heating buffer

The Hygenik is only used to provide domestic hot
water and is loaded under priority by the priority val-
ve.

The heating is supplied by an extra buffer.

The heating circuit can be a pumped or mixed cir-
cuit, whereby it is recommended to fit a mixing val-
ve.
