The energy demand of the outdoor pool Borssum in Emden was reduced by almost 85% thanks to the use of a 1900 m² absorber plant for pool water heating and a 15,5m² flat plate surface area collector for service water heating. The average pool water temperature is ensured during the whole season due the the use of a heating pump during bad weather conditions. This solar plant serves not only the outdoor pool but also a neighbouring super market. Thus the produced solar energy is used not only in the pool opening season, but all over the year.

Since the complete renovation of the open swimming pool Hänigsen in Niedersachsen, the pool water has not been warmed up any more with oil as an energy source, but with solar energy. As a consequence, the community of Ütze can save about 20.000 €. The pool water is warmed with 580m² of Sportsolar and 160m² of Classisolar absorbers. The SportSolar absorber from the company SOLKAV is not installed on the roof of any building, but it is integrated around the edge of the swimming pool. This type of absorber saves the costs of the traditional heating system, as well as the cost of the material used to cover the area surrounding the pool border.

The Friedrich-Ludwig-Jahn swimming pool located in Benshausen, was originally constructed in 1934. In the years 1999 to 2000 the facilities were completely modernized with the newest technologies. Benshausen is located in the Thüringer forest, i.e., the Region with the least amount of sun hours per year. Before the renovations were undertaken the pool water was not warmed. However, it was clear that the long term solution to attract more visitors was to warm up the pool water. In order to keep the pool running costs as low as possible, it was planned to implement solar thermal absorbers as heating system. The absorber system was finally installed in the year 2001. The 370 m² of absorber were installed on the roofs of the changing rooms, toilets and carports. The absorber system warms up the pool water to a temperature of 24°C. Once the target temperature has been reached the system is automatically switched off. The investment costs for the absorber system of 30.504 € were paid off in a period of four and a half  years, although the admission fare of 2 € per day lies well below that of other conventionally heated open swimming pools in the vicinity (from 3 to 3,5 €). The specifi c costs of the solar energy for the warming of the water pool lie under 1,5 ct/kWh, if a minimum use period of the absorber system (25 years) is considered.

The outdoor swimming pool Grünhöfe was opened on 01.07.1961. In the seventies, a system to heat the pool water was installed. Since the year 2006, the outdoor pool Grünhöfe has been deeply renovated. In 2007, it was decided to replace the old heating system with a solar one. The 820m² of absorber area were installed on the roof of the single available building in place. The absorber system reached a temperature of 26° C during the first year of operation, i.e. 2008; at such high temperatures the solar heating system is automatically switched off. The minimum temperature reached during the same period was 20° C. The results from the first year of operation fulfilled all the expectations.

This private outdoor swimming pool was built with surface of 28,5 m² after 4 years without heating and was assembled with the solar tube absorber VIVOfl ex standard system in 1993. The relation between pool water and absorber surface accounts 4 to 3. In the low season the pool water can be heated fast by 2 till 3 degrees on sunny days. During the peak season the water temperature is average 4 till 5 degrees higher. Installation costs were minimized because the installation of the solar absorber has been done by the owner himself. Simply the integration into existing fi lter circuit as well as the installation of solar control took place by a specialty firm. The system works for 10 years now and means enrichment for the whole family because the swimming pool can be used more often than in the fi rst years without solar heating; and: the heating is gratis.

The private swimming pool was build in 2004 in SOLPOOL D07 combination with an 18 m² solar thermal absorber system VIVOfl ex Standard. The pool got a surface area of 23 m². The fl at roof is nearly free of shadow and is suited as base for the ribbed tube absorber. The roof secures that the pool doesn’t cool down to much at night and the pool water reaches comfortable temperature till 25 °C even in the low season. On account for this the swimming pool can be used from the beginning of April to the end of October.
