Winter air conditioning and DHW production system consisting of
an indoor unit HUB RADIATOR PLUS SOLAR 250 equipped with
a double inverter circulator, to serve n. 2 hydronic circuits, one at
high temperature and one at low temperature.
The system is powered by n. 2 HR 7.8 boosters working in cascade
with load partialization steps on n. 2 separate and independent
thermodynamic circuits combined with a forced circulation solar
thermal system which integrates both the thermal and sanitary
parts.
