4 Technical data
3 Product description
The solar storage cylinders Riello 7200/2 HV PLUS can be
integrated into solar systems for the production of do-
mestic hot water.
The main technical elements of the design of the solar
storage cylinder are:
- the careful study of the geometries of the tank and the
coils that allow you to obtain the best performance in
terms of stratification, heat exchange and reactivation
times
- the regulation of the connections to various heights for
employing various types of heat generators, without
influencing the stratification
- the polyurethane insulation without any CFC and the
elegant outer covering to limit dispersion and to im-
prove efficiency
- the use of the flange to facilitate cleaning and mainte-
nance, and the magnesium anode with an "anti-corro-
sion" function
The Riello 7200/2 HV PLUS storage cylinders can be equipped
with a specific solar regulator and they can easily be in-
serted into solar system where the boilers or thermal sys-
tems act as auxiliary producers of heat.
