Vacuum tube solar collectors.
Absorber surface area: 22 and 32 sq.ft - 2 and 3 sq.m
The most environmentally-friendly method of domestic hot water heating, as well as a backup/supplement for low-temperature heating purposes.
Thanks to the highly effective Sol-Titan coating, the vacuum tube collector Vitosol 300 can even utilize diffused solar radiation. It is therefore suitable not only for domestic hot water applications, but also as a backup for central heating purposes.
The benefits at a glance:
- High level of operational reliability and a long service life thanks to the use of high-grade, corrosion-resistant materials such as special solar glass, copper and stainless steel. Durable, vacuum-tight glass-to-metal seal.
- High efficiency thanks to the Sol-Titan coated absorber and vacuum collector tubes.
- Energy-efficient Duotec wrap-around pipe heat exchanger, which almost completely encases the condensers to facilitate better heat transfer.
- The condenser has a flexible connection to the vacuum tube via a stainless steel corrugated pipe. The individual tubes can be adjusted for optimum alignment to the sun during original placement.
- The dry connection of the collector tubes allows for individual tubes to be mounted and disassembled without having to drain the solar heating system.
- Proven Viessmann plug-in system for connecting several collectors to form one collector panel with a total surface area of up to 65 ft2 - 6 m2.
A fully integrated solar system package available:
- Vitosol 300 vacuum tube collectors
- Vitocell 100 or 300 hot water storage tank
- Solar-Divicon pump station
- Vitosolic control unit

For the Vitocell-B 100 the heat from solar collectors is transferred to the water via the lower heat exchanger coil. The upper heat exchanger coil accommodates reheating by the heating boiler.
The 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 domestic hot water temperature at the top of the tank and at midpoint.
For the Vitocell-B 300 the heat from solar collectors is transferred to the water via the lower heat exchanger coil. The upper heat exchanger coil accommodates reheating by the heating boiler. The narrow, cone-shaped heat exchanger coils and their design provide maximum energy transfer in connection with Viessmann solar collectors.
The benefits at a glance:
- Long service life due to corrosion-resistant hot water tank and heat exchanger coil construction of high-alloy SA240-316Ti stainless steel.
- No sacrificial anode required for additional corrosion protection; therefore no anode replacement costs.
- Heating of the entire water content by a heat exchanger coil extending to the tank bottom.
- Reliable hot water comfort due to fast, even heating with large-diameter 1"/25 mm non-finned heat exchanger coil.
- Minimal standby losses through highly effective foamed-in-place or wrap-around HCFC-free insulation.
- Two thermometers to show the domestic hot water temperature at the top of the tank and at midpoint.
