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.
