DocumentDocumentTechnical Data Manual Model Nos. and pricing: see Price List Vitocell 100-B CVBB and CVB Series Dual-coil, indirect-fired domestic hot water storage tank 79 USG and 119 USG (300 L and 450 L) capacity Indirect-fired domestic dual-coil hot water storage tank steel construction, 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. Product may not be exactly as shown CAUTION This tank version is not suitable for steam heating applications. 5699 335 - 01 12/2015 Product Information Benefits 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: Corrosion-resistant tank with Ceraprotect enamel coating ensures a long service life. Additional cathode protection is provided by a magnesium anode. 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. Large heat exchanger surfaces allow fast and even heating of the entire water content, guaranteeing a high level of domestic hot water comfort. Increased energy savings thanks to highly effective, foamed-in-place HCFC-free insulation keeping standby losses at a minimum. Two thermometers to show the DHW temperature at the top of the tank and at the midpoint of the tank. The Vitocell-B 100 119 USG (450 L) capacity tank is supplied with removable soft PET insulation for easier handling. 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. 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.

A domestic hot water tempering valve must be used. Vitocell 100-B, CVB/CVBB Series Technical Data 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. 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.

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 final 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.
