The Austrian solar thermal market is characterized by a broad diversification in terms of different applications. The applications range from domestic hot water systems and combi-systems for single family houses, which together covered about 60% of the market in 2011, medium-scale systems (50 - several hundred m² collector area) for multi-family houses, hospitals and hotels and large-scale systems (0.5 - 3 MWth) used for district heating and industrial process heat. Also a significant number of solar cooling and air-conditioning systems were installed. Swimming pool heating is as well an application, but with a rather small market share compared to the total.
In 2011 a total of 236.240 m² (65,4 MWth) were installed in Austria. This collector area can be subdivided into 221.500 m² (155,1 MWth) flat-plate collectors, 8.690 m² (6,1 MWth) evacuated tube collectors, 5.700 m² (4 MWth) unglazed swimming pool absorbers and 350 m² (0,2 MWth) solar air collectors.
