Solar air heating and drying – an attempt to assess the world market
Solar air heating for space heating and drying is one of the most economical uses of solar thermal. However, solar air heating is rarely reported on and there are few reliable market figures.
Solar Heat Worldwide still has the most comprehensive data. It reported a world market excluding China of 21,073 m2 in 2021, a plus of 21 % compared to 2020. Growing demand was reported from Spain and Turkey, and declining market volumes from the USA and Canada. But these figures only partially capture the dynamic development of individual solar air heating providers as not all organizations provide data in the segment of air heating.
