Product Information
Vitocell 300-V
Fully hygienic, efficient and economical
domestic hot wa ter production with DHW
tanks of high-grade stainless steel – vertical
version.
The benefits at a glance:
H Corrosion-resist an t tank of high-grade SA
240-316 Ti stainless steel offers a long
service life.
H Fully hygienic due to high quality
homogeneous stainless steel surfaces.
H The high alloy material is immune to
cracking or peeling. The tank stays
hygienic and re quires only minim um
service.
H Does not require a consumable anode for
corrosion protection.
H The entire water content is heated by a
1¼” / 32 mm diameter stainless steel
heat exchanger surface which extends to
the bottom of the tank.
H Certified to CSA Low Lead Content
Certification Program;
including US Safe Drinking Water Act,
NSF/ANSI 372 as well as other applicable
US State requirements.
H The positioning of the tubular heat
exchanger coil further ensures that 82 to
97% of the tank volume can be drawn at
constant water temperature.
H The stainless s teel heat exchanger coil is
self-venting towards the top and
self-draining towards the bottom,
therefore not susceptible to reduced heat
transfer due to air lock or deposits.
H Universally suitable – for applications
requiring larger quantities of hot water,
multiple vertical tanks can be combined
via headers to form tank batteries.
H Standby losses minimized by 2 ¼”/
58 mm highly effective, foamed-in-place
or 4”/100 mm wrap-around PET insulation
HCFC-free insulation.
H Easy transport into mechanical room due
to low weight and compact construction.

Technical data
The 79 and 119 USG / 300 and 450 ltr tank sizes may be combined into a battery consisting of between 2 and 4 tanks.
Tank batteries consisting of more than 4 tanks can be installed by creating up to 4 batteries, each consisting of 4 tanks. The heating
contractor is responsible to ensure proper piping on both the primary and secondary circuits.

Product Installation
WARNING
To ensure optimum, safe operation,
the supplied stainless steel well must
be installed. The well diameter is
large enough to accommodate a wide
variety of sensing bulbs.
Always use spring clip to ensure
proper contact of capillary bulb
against the stainless steel well for
proper sens ing/heat transfer!
Heating water supply temperatures
over 230°F / 110°C
For these operating conditions, an approved
high limit safety aquastat m ust be installe d
to limit the domestic hot water temperature
to 203°F / 95°C in the tank.
Recirculation tapping
The recirculation tapping is on a separate
tapping (see page 5). Cap this opening if the
tank is not installed with recirculation.
Backflow 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.
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 100 psig where a CRN is
required. Maximum operating pressure is
150 ps ig.
The T&P relief valve supplied with the tank
is ASME pressure steam rated for 998 MBH
and CSA temperature steam rated for
200 MBH. It is tested under ANSI Z21.22
code for Relief Valves and Automatic Gas
Shut-off Devices for Hot Water Supply
Systems.

Warranty excerpt
Our warranty for domestic hot water tanks
states that the water heated should be of
drinking water quality and that any water
treatment equipment in use must function
correctly.
If the product has been improperly installed
or misapplied by the installer, contractor or
final user, Viessmann accepts no
responsibility for damage howsoever caused
and reserves the right to withdraw the
product warranty. In order to qualify for
product warranty, strict a dherence to the
installation and s ervice manuals must be
observed. In the event that components not
approved by Viessmann are utilized,
Viessmann res erves the right to withdraw all
expressed or implied warranties without
written notice.
The water to be heated with the Vitocell
must be drinking (potable) wa ter 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.

Continuous Flow Capacity Chart
Example: Vitocell 300-V, 119 USG / 450 ltr capacity
Assume boiler output to tank is 238 MBH. Enter chart at left and draw horizontal line ac ross to recovery rate of 284 GPH / 4.7 GPM for
140°F / 60°C domestic hot water under column A. Where the horizontal line intersects the 194°F / 90°C curve is the point of intersection
for the diagonal line used to size the pum p. The diagonal line begins at the or igin and goes through the point of intersection extending up to
the top of the chart. Read between the reference diagonal lines to get a pump specification of 20 GPM at 8.4 ft. To summarize: For a
Vitocell-V 300 with 119 USG / 450 ltr capacity and 238 MBH input, the boiler water temperature is 194°F / 90°C, difference between
boiler return and supply water temperature is 29°F / 16°C, recovery rate is 4.7 GPM of 140°F / 60°C DHW, a nd the pump required is 2 0
GPM, 8.4 ft. plus pressure drop in piping and boiler. If a multiple-tank application is required, i.e. 4 tank s at 238 MBH input each, then the
pump selection would be (4 x 20 GPM) 80 GPM at 8.4 ft. plus piping pressure drop.
