Product Information

VITOCELL 300-H
Vitocell 300-H
Fully hygienic, efficient and economical
domestic hot water production with DHW
tanks of high-grade stainless steel – horizontal
version.
The benefits at a glance:
HCorrosion-resistant tank of high-grade SA
240-316 Ti stainless steel offers a long
service life.
HFully hygienic due to high quality
homogeneous stainless steel surfaces.
HThe high-alloy material is immune to
cracking or peeling. The tank stays
hygienic and requires only minimum
service.
HThe entire water content is heated by a
1¼” / 32 mm diameter stainless steel
heat exchanger surface which extends to
the bottom of the tank.
HCertified to CSA Low Lead Content
Certification Program;
including US Safe Drinking Water Act,
NSF/ANSI 372 as well as other applicable
US State requirements.
HThe positioning of the tubular heat
exchanger coil further ensures that 82 to
97% of the tank volume can be drawn at
constant water temperature.
HThe 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 sediment
deposits.
HStandby losses minimized by 2¼” /
58 mm highly effective, foamed-in-place
HCFC-free insulation.
HEasy transport into mechanical room due
to low weight and compact construction.

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”. Please also refer to the corresponding sizing chart at the end of this manual.
*2
Measured values are based on a room temperature of 68 ºF / 20 ºC and a domestic hot water temperature of 149 ºF / 65 ºC and can
vary by ±5 %.
*3
To overcome mechanical room access problems, the front panel with thermometer and side panels can be removed, the adjustable feet
unscrewed, and the Vitocell 300-H turned on its side.
*4
This is the net width of the Vitocell 300-H after removing the outer casing to ease problems of access into the mechanical room.

Measured values are based on a room temperature of 68 ºF / 20 ºC and a domestic hot water temperature of 149 ºF / 65 ºC and can
vary by ±5 %.
Installation of additional aquastat(s)
Ensure that temperature tempering valve(s)
is/are 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.

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.

VITOCELL 300-H
Sensor Well
Vitocell 300-H,
with 42 and 53 USG / 160 and 200 ltr
capacity
The sensor well is welded into the DHW
tank.
Vitocell 300-H,
with 92 and 119 USG / 350 and 450 ltr
capacity
Heating water supply temperatures
over 230°F / 110°C
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.
Vitocell-H domestic hot water tank
positioned under the boiler
Please note that only the boiler/tank
combinations stated in the Price List are
possible. In the case of the 92 USG / 350 ltr
capacity Vitocell 300-H , the boiler can only
be positioned on the DHW tank so that it is
flush at the front.
Recirculation tapping
The recirculation tapping on the Vitocell-H
300 is also the opening for mounting the
temperature and pressure relief valve.
If this opening is utilized for recirculation,
extend the stainless steel nipple on the tank
with a brass tee of the same size as the
stainless steel nipple ∅to accommodate
both connections; see installation
instructions.
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 psig.
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.
For steam applications, a field supplied 1”
T&P valve must be utilized.

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 adherence to the
installation and service manuals must be
observed. 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.
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.

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!

Example: Vitocell 300-H, 119 USG / 450 ltr 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 15 GPM at 4.5 ft. To summarize: For a
Vitocell-H 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 31°F / 17°C, recovery rate is 4.7 GPM of 140°F / 60°C DHW, and the pump required is 15
GPM, 4.5 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 15 GPM) 60 GPM at 4.5 ft. plus piping pressure drop.
