Riello 7200/2 HV PLUS
3 Product description
The solar storage cylinders can be integrated into solar
systems for the production of domestic 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
- the use of the magnesium anode with an "anti-corro-
sion" function
The storage cylinders can be equipped with a specific so-
lar regulator and they can easily be inserted into solar
system where the boilers or thermal systems act as auxil-
iary producers of heat.
