All cylinders are supplied with thermal insulation. Cylinders with "-A"
(e.g. CUGA-A) or "-A+" (e.g. EVIA-A+) in their type designation are
additionally equipped with vacuum-insulated panels, enabling them
to achieve ErP energy efficiency class A or A+ respectively.

2.3 Intended use of Viessmann cylinders

The appliance is only intended to be installed and operated in sealed
unvented systems that comply with EN 12828 / DIN 1988, or solar
thermal systems that comply with EN 12977, with due attention paid
to the associated installation, service and operating instructions.
DHW cylinders are only designed to store and heat water of potable
water quality. Heating water buffer cylinders are only designed to
hold fill water of potable water quality. Only operate solar collectors
with the heat transfer medium approved by the manufacturer.
Intended use presupposes that a fixed installation in conjunction with
permissible, system-specific components has been carried out.
Commercial or industrial usage for a purpose other than heating the
building or DHW shall be deemed inappropriate.

Freshwater modules of the type for installation on the heating water
buffer cylinder include a DHW circulation pump and a diverter valve
for directed return stratification (also available for wall mounting as
an option).
All pumps are highly efficient.
With types PBMA (48 l/min) and PBLA (68 l/min), cascades with up
to 4 identical modules are possible.

Vertical cylinders with a nominal capacity of ≤ 300 l are encased in
foam, as are horizontal cylinders. Vertical cylinders with a nominal
capacity of > 300 l are supplied with separate thermal insulation.
Any usage beyond this must be approved by the manufacturer for
the individual case.
Incorrect usage or operation of the appliance (e.g. the appliance
being opened by the system user) is prohibited and results in an
exclusion of liability.
Incorrect usage also occurs if the components in the system are
modified from their intended use (e.g. through direct DHW heating in
the collector).
Adhere to statutory regulations, especially concerning the hygiene of
potable water.
