Swimming halls are very well suited for solar thermal production. Typically, their heat consumption is big and the required temperature level tends to be relatively low. In such cases solar thermal collectors are operating with a very high efficiency.
However, quite often swimming halls are closed some time of the year and summertime closure may mean extra challenges for solar heat supply.
For Hämeenlinna swimming hall Savosolar solved this issue by feeding surplus solar energy in summer to the nearby district heating network. Thus, the solar system is producing heat all days and depending on the swimming hall’s actual heat demand, the facility is either a district heating provider or a consumer.
Savosolar was happy to sign its so far largest delivery contract with Grenaa Varmeværk in 2018. Savosolar’s highly efficient Savo 15 premium collectors are installed right next to an existing solar collector field which had been commissioned in 2014.
In this turn-key project Savosolar acts as the main contractor enlarging the solar fraction of the district heating network. Its operator, Grenaa Varmeværk, is producing about 146,000 MWh of heat per year. By using solar thermal it has managed to keep their customers´ heat price among the lowest in the whole of Denmark.
The new solar field with Savosolar collectors will increase the overall solar yield and ensure lowest energy production costs also in the future.
Under construction
Lübeck, Germany (largest solar thermal plant in Schleswig-Holstein federal state)
Summa Energy has been selected as general contractor to build a 9 MW solar thermal system on behalf of Stadtwerke Lübeck Energie GmbH for its district heating network, which supplies households in the Moisling city district with healthy heating. Only 788 pieces of Savo 16S large scale high performance flat plate collectors are sufficient to getting combined with an 3,000 m³ heat storage tank and produce carbon free heat for the needs of all connected consumers.
Additionally, a PV system will be built on site to generate the electricity consumed by the solar pumps, thus unburdening the local power grid.
The scope of supply includes also all the land works, the construction of a technical building and the supervision system to operate the plant in automatic mode.
At Summa Energy we help our customers to achieve success in their business and environmental work, while striving for the best possible customer satisfaction. See what Mr Peter Blaser, general manager of Fernwärme Ettenheim GmbH, says about our first delivery to Germany.
