Vitocell 100-B
CVB Series
Vertical indirect-fired dual coil domestic hot water storage tan
made of steel with Ceraprotect enamel coating
ne heat exchanger coil facilitates heat transfer from the solar
collectors to domestic hot water, a second heat exchanger coil
allows reheating of the water content by the hot water heating
boiler.

Product Information

Product Information
Domestic hot water storage tank of corrosion
protected steel with built-in insulation made
of PUR Foam.
Fully hygienic, efficient and economical
domestic hot water production by solar
collectors and a hot water heating boiler.
Heat from the solar collectors is transferred
to the domestic hot water via the lower
tank coil.
Benefits at a glance:
HCorrosion-resistant tank with Ceraprotect
enamel coating ensures a long service life.
Additional cathode protection is provided
by a magnesium anode.
HThe entire water content is heated by a
coiled 1”/25 mm diameter steel heat
exchanger surface which extends to the
bottom of the tan .
HLarge heat exchanger surfaces allow fast
and even heating of the entire water
content, guaranteeing a high level of
domestic hot water comfort.
HIncreased energy savings thanks to highly
effective, foamed-in-place HCFC-free
insulation keeping standby losses at a
minimum.
HTwo thermometers to show the DHW
temperature at the top of the tank and at
the midpoint of the tank.
HThe Vitocell-B 100 119 USG / 450 L
capacity tank is supplied with removable
soft PET insulation for easier handling.
HFor dual-mode DHW heating with solar
panels in conjunction with a boiler. The
solar energy gathered by the solar panels
is transferred to the DHW by the lower
indirect coil. For mono-mode DHW heating
with a boiler or heat pump - both indirect
coils can be connected in series.

Due to the potentially high DHW
temperatures generated by the solar
heating system, the domestic hot
water temperature must be limited to a
maximum of 140°F/60°C by installing
a mixing device, e.g. a thermostatic
mixing valve. The mixing device does
not completely eliminate the ris of
scalding at the tap. The installation of a
mixing tap is required.

Heating water supply temperature
over 230ºF / 110ºC
These operating conditions require the
installation of an additional safety high limit
into the DHW storage tank, preventing the
domestic hot water temperature from rising
above 203 ºF/ 95 ºC. A domestic hot water
tempering valve must be used.
Temperature and pressure
relief valve
A temperature and pressure relief valve
(T&P relief valve) is supplied with the tank.
The heating contractor must install the
valve on each tank in a method meeting
code requirements. If local codes require a
different relief valve, substitute the
manufacturer’s supplied valve. The tank is
approved for 150 psig. Maximum operating
pressure is 150 psig.
The T&P relief valve supplied with the tank
is tested under ANSI Z21.22 Code for Relief
Valves and Automatic Gas Shut-off Devices
for Hot Water Supply Systems.
Bac flow preventers
Where backflow preventers are required, a
domestic water expansion tank installation
is recommended in the cold water inlet
piping before the cold water enters the
Vitocell. For the backflow device, observe
local plumbing codes and regulations.

Warranty excerpt
ur warranty for domestic hot water tanks
states that the water to be heated must be
of drinking (potable) water quality and that
any water treatment equipment in use must
function correctly.
Viessmann accepts no responsibility for
damage howsoever caused and reserves the
right to withdraw the product warranty if the
product has been improperly installed or
misapplied by the installer, contractor or end
user. In order to qualify for product warranty,
strict adherence to the installation and
service manuals must be assured. In the
event that Viessmann non-approved
components are utilized, Viessmann reserves
the right to withdraw all expressed or implied
warranties without written notice.
The water to be heated with the Vitocell
must be drinking (potable) water quality. If
the tank is used to heat other media, the
warranty will be null and void. Damage
resulting from excessive pressure or
temperature is clearly not the responsibility
of Viessmann.
The amount of chloride and sulfate
acceptable to the tank is limited. In areas
where high concentrations of chloride and
sulfate are present in drinking water, please
consult Viessmann for directions.
For full warranty details, please read the
product warranty card.
