Hot water and space heating

Consti Talotekniikka

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.
