Flat-plate collector with integrated tank
Natural circulation solar thermal panel for hot water production
-
Entirely built by Viessmann
The Vitosol 111-F solar system is self-contained, panels and cylinder. The cavity cylinder is constructed in such a way as to avoid a sanitary expansion tank, thus optimising space and costs.
-
Fastenings in high-quality materials
Whether we are talking about pitched or flat roofs, the components supplied by Viessmann are designed in-house and certified for wind and snow, made of stainless steel high-grade aluminium or painted steel to prevent corrosion over time.
-
Continuous profile frame construction
The panel is constructed with a seamless, continuous profile aluminium frame or painted steel. This type of construction provides solidity and strength for many years

Vitosol 111-F Solar Thermal System
Solution with natural circulation solar thermal panel for hot water production
The advantages at a glance
- Flat solar panel with highly selective coating for high utilisation of solar energy
- Universal use, on pitched and flat roofs
- Integrated tank with Ceraprotect enamelling for high domestic water quality
- Easy installation and commissioning
- Closed solar circuit and use of corrosion-resistant materials for a long service life and high reliability
- High operational safety due to integrated pressure/temperature relief valve.
The Vitosol 111-F solar panel is a (factory made) natural circulation solar thermal system with flat-plate solar panels and a highly insulated steel cylinder for outdoor use, ensuring efficient domestic hot water production.
How does a natural circulation solar panel work?
A solar panel is filled with an antifreeze fluid to transport heat from the panel to the cylinder. The panel absorbs solar radiation and heats the fluid, which expands and circulates naturally to the cavity of the cylinder. Here, heat is transferred to the sanitary side and the cooled fluid flows back to the lower part of the panel.
In a naturally circulating solar thermal panel, this cycle occurs spontaneously; no circulation pump is used, and consequently there is no electricity consumption.
