Put the sun to work for you

The high performance Vitosol 200-FM flat plate solar collector is the ideal addition to every heating system. With an absorber area of 25 sq ft (2.3 sq m), the solar collectors can be adapted to meet any energy demands.

On average, they replace up to 60 percent of the energy required for DHW heating annually and contribute to central heating backup. In conjunction with a condensing boiler, free solar energy allows you to reduce your annual energy consumption for heating and DHW by more than one third.


ThermProtect prevents overheating

An intelligent absorber layer protects the collectors from overheating. Viessmann's patented ThermProtect technology switches the solar collectors off when they reach a specific temperature. Temperatures of 167°F (75°C) and above cause changes in the crystalline structure of the absorber layer, increasing the rate of heat radiation and reducing the collector output. ThermProtect significantly lowers the max temperature inside the collector and prevents steam formation in the solar circuit.
When the collector temperature is lowered, the crystalline structure reverts to its original state. More than 95 percent of the incoming solar energy will then be absorbed and converted into heat. Only the remaining five percent is reflected. There is no limit to the number of times the crystalline structure can reverse, making this function available at all times.
