|"Solar swimming pool heating with unglazed absorbers is, economically speaking, the most interesting application in the area of solar-thermal utilisation. For hotels in Southern Europe, the question of how to exploit solar energy often arises in the summer months, since the swimming pool water is already heated sufficiently by the air temperature and direct solar radiation alone. The Solarthermie² system solves this problem with the novel concept of utilising the summer excess for drinking water heating. This kills two birds with one stone: extending the operating period of the swimming pool in the winter term and cost-effective drinking water heating during the summer months. It only now remains for this concept to become a model for hotels in southern holiday regions."
Berlin, Dipl. Ing. Michael Thoma, Energy commissioner of the Berliner Bäderbetriebe:
|"For the Berlin baths, solar absorber systems are a practical solution for reducing operating costs and meeting climate protection goals."
Absorber systems have already been installed in well over 2,000 municipal pools in D-A-CH!
Dipl. Ing. (FH) Ralf Orths, Wagner Solar GmbH:
|"Solar absorber pool hearing systems are not promoted financially in Germany because of the relatively short amortisation period.“
An economical and effective method. The bathing season can be extended significantly.
Combination of 1 and 4.
A practical solution when constant temperatures are required, e.g. for training and competition pools!
The easiest and most economical method.
High temperature fluctuations and short times of use, depending on the region.
The most expensive and environmentally harmful method.
Guarantees constant water temperatures, causes high energy costs and high CO2 emissions!
