Vacuum tube collectors 

Effective use of the sun's energy – with their highly selective coating, the absorbers collect a vast amount of solar energy and thereby ensure high efficiency. At the same time, the vacuum in the tubes provides very effective thermal insulation. 

This means there are almost no losses between the glass tubes and the absorber, enabling the collector to convert even low levels of insulation into useful energy. The vacuum tube collectors use the available insulation extremely efficiently, particularly in the spring and autumn, as well as in the winter when outside temperatures are low.

Design & Technology

With more than 30 years' experience in the development and manufacture of solar thermal systems, you can count on our high quality and technical expertise. It makes no difference whether you opt for a new condensing boiler for oil or gas, a heating system for wood, or a heat pump – all Viessmann systems are designed to work in combination with solar technology.

Solar tube collector

High energy yields for years to come

Viessmann vacuum tube solar collectors are designed for an exceptionally long service life. This is guaranteed by the use of high grade, corrosion-resistant materials, such as glass, aluminium, copper and stainless steel. 

The absorber is an integral part of the vacuum tube. This protects it from weather influences and contamination, and ensures high energy yields for years to come.

Quick and safe installation

Vitosol tube collectors are delivered in a pre-assembled modular design. An innovative push-fit system enables the tubes to be quickly and easily installed. The tubes can be rotated individually for optimum alignment with the sun. 

The tubes are connected in a dry state, i.e. without direct contact between the process medium and the solar medium, allowing individual tubes to be replaced without draining the system. Individual collectors are interconnected by stainless steel corrugated push-fit connectors.
