Design heating system

Of course, a house can also be heated using solar thermal energy. It depends on the number of collectors, the size of the storage tank, and the system itself. Surface heating such as underfloor heating at 32°C or wall heating at 28°C with proper design would be optimal. Additionally, a proper hydraulic system is needed, and then it works. This works excellently in Austria and even more so in Poland. I can recall a car dealership we built in the deepest part of Poland with solar and geothermal energy. It hardly needs any additional heating in winter, and the rooms constantly have 22°C at outside temperatures of . 25°C. Regards Energy Buildings
