Benefits
Product Information
Fully hygienic, efficient and economical domestic
hot water production with DHW tanks of high-grade
stainless steel – vertical version.
Benefits at a glance:
Corrosion-resistant tank of high-grade SA 240-316
Ti stainless steel offers a long service life.
Fully hygienic due to high quality homogeneous
stainless steel surfaces.
The high-alloy material is immune to cracking or
peeling. The tank stays hygienic and requires only
minimum service.
Does not require a consumable anode for corrosion
protection.
The entire water content is heated by a 1¼ in. (34 mm)
diameter stainless steel heat exchanger surface which
extends to the bottom of the tank.
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.
The stainless steel 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.
Universally suitable – for applications requiring
larger quantities of hot water, multiple vertical tanks
can be combined via headers to form tank batteries.
Standby losses minimized by 2¼ in. (58 mm) highly
effective, foamed-in-place or 4 in. (100 mm) wrap-
around PET HCFC-free insulation.
Easy transport into mechanical room due to low
weight and compact construction.
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.

The stated recovery rate is only achieved when the rated output of the boiler is equal to or greater than that
stated under “Recovery rates”.
*2 Measured values are based on a room temperature of 68°F (20ºC) and a domestic hot water temperature of
149°F (65ºC) and can vary by ± 5%.
*3 For other dimensions, see illustrations and table on page 4.
*4 Adjustable feet can be adjusted up to 2 in. (50 mm).

Ensure that temperature tempering valve(s) is installed
if the domestic hot water storage tank temperature
exceeds 140°F (60°C) to protect from scalding.
Consult plumbing codes and authorities for local
requirements.
WARNING
In a multiple-tank installation, it is recommended that an
additional high limit aquastat be installed in the common
domestic hot water supply header to the system. This
aquastat should be wired in series to the operating
aquastat on the tank battery. The setting on this
additional high limit aquastat should be approximately
9°F (5°C) higher than the operating high limit.
*1 When planning for the recovery rate as stated or calculated, allow for the corresponding circulation pump.
The stated recovery rate is only achieved when the rated output of the boiler is equal to or greater than that
stated under “Recovery rates”.
*2 Measured values are based on a room temperature of 68ºF (20ºC) and a domestic hot water temperature of
149ºF (65ºC) and can vary by ±5%.

Technical Data
Example: Vitocell 300-V, 119 USG (450 L) capacity
Assume boiler output to tank is 238 MBH. Enter chart at left and draw horizontal line across 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 pump. The diagonal line begins at the
origin 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 L) 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, and the pump required
is 20 GPM, 8.4 ft. plus pressure drop in piping and boiler. If a multiple-tank application is required, i.e. 4 tanks 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.

Sensor well
The supplied stainless steel sensor wells are to be used
for control sensors to ensure maximum operational safety.
Should the supplied sensors not fit into the sensor wells,
other stainless steel sensor wells must be used.
For solar heating systems, Viessmann recommends
placement of the DHW tank temperature sensor in the
solar collector return. This requires a brass elbow with
sensor well included in the accessory pack.
Heating water supply temperature over 230ºF (110ºC)
For these operating conditions, an approved high limit
safety aquastat must be installed 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.
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
sensing/heat transfer!
Warranty consideration
Viessmann DHW tanks require 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 adherence
to the installation and service manuals must be observed.
In the event that components not approved by Viessmann
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
sheet.

Temperature and pressure relief valve
A 150 psi 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 Canadian Registration Number (CRN) is required.
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.
