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.

The upper coil is designated for connection to a hot water heating boiler or a heat pump.

The lower coil is designated for connection to solar collector panels or heat pumps.

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 “ ecovery

rate”.

Measured values are based on a room temperature of 68°F / 20 ºC and a domestic hot water temperature of 149°F / 65 ºC and can vary

by 5%.

For other dimensions, see illustration and table on page 5.

Thermostatic mixing valve/anti-scald

valve for solar applications (field

supplied)

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.

For solar heating systems, Viessmann

recommends placement of the DHW tank

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.
