TERRA SWM HGL with mixing circuit and solar
With priority charging, the top reservoir area is charged with the speed-regulated charging pump to the set
HGL temperature. In heating mode of the heat pump, too, a partial
fl
ow with the set HGL temperature is always
charged in the upper reservoir area via the HGL exchanger and the HGL valve. This means that the Hygienik
is always kept at the correct temperature. The solar system loads
fi
rst the upper part of the Hygienik 2.0. Due
to the high solar temperatures it is recommended to use a hot water station with mixing valve.
