Vitosol 100-FM SVKF (on roof) Slates 2 Panels 4.04m2

Vitosol 100-FM
Patented by Viessmann; the switching absorber coating protects high-performance flat-plate collectors against overheating and stagnation.
The high-performance flat-plate collectors are an ideal addition to any heating system. With a kit total absorber area of  4.04m2, these solar collectors adapt to specific energy requirements. On average, they replace up to 60 percent of the energy required to heat domestic hot water every year. When combined with a condensing boiler, users can even cut their annual energy consumption for heating hot water by more than a third.

Straightforward system engineering.
The temperature-dependent shutdown of these two collectors is entirely independent of system configuration and control unit settings. Solar thermal systems are, therefore, completely fail-safe. The thermal loads on system components and the heat transfer medium always stay within their normal range. This increases service life and operational reliability compared to conventional solar thermal systems. In addition to robust operation, collectors with temperature-dependent shutdown are also more tolerant of incorrect sizing.

Features and benefits:

• High operational reliability and long service life thanks to lower stagnation temperatures
• Independent of controller settings, power failures and mechanical devices (e.g. dampers)
• Significantly lower stress on system components
• Can easily be sized for large plants
• Immediate restart after system standstill
• Simplified component selection (e.g. smaller expansion vessels)
• Benefits for the user:
• No overheating problems in summer or when residents are away from home
• Higher solar coverage for central heating backup and DHW heating
