VITOCELL-B 100

Dual coil domestic hot water storage tank

79 and 120 USG / 300 and 450 ltr

Vitocell-B 100

CVB Series

Vertical indirect-fired dual coil domestic hot water storage tank made of steel with Ceraprotect enamel coating

One 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.

This tank version is not suitable for steam heating applications.

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:

H

Corrosion-resistant tank with

Ceraprotect enamel coating ensures a long service life

.

Additional cathode protection is provided by a magnesium anode.

H

The entire water content is heated by a coiled

1”/25 mm diameter steel heat exchanger surface which extends to the bottom of the tank

.

H

Large heat exchanger surfaces allow fast and even heating of the entire water content,

guaranteeing a high level of domestic hot water comfort.

H

Increased energy savings

thanks to highly effective, foamed-in-place HCFC-free insulation keeping standby losses at a minimum.

H

Two thermometers

to show the DHW temperature at the top of the tank and at the midpoint of the tank.

H

The Vitocell-B 100 120 USG / 450 L capacity tank is supplied with removable soft PUR Foam insulation for easier handling.

H

For

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 “Recovery 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.

WARNING

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 risk of scalding at the tap. The installation of a mixing tap is required.

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 manufactured by Watts Industries (Model

40XL-8), set to 150 psig for US and

Canadian installations (100 psig for

Canadian installations for 120 USG / 450 ltr size tank only). The valve 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.

The relief temp. is set at 210°F / 99°C. The valve has a male threaded inlet and female threaded outlet, both ¾” sizes.

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.

Warranty excerpt

Our 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.

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.
