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.

Energy production

Onnelanpolku

Onnelanpolku nursing home, which was built in 2013, is a so-called near zero energy building. To achieve this classification, the building needs to be well insulated and some of the consumed energy needs to be produced locally. A hybrid heating system for DHW and space heating was realized with the combination of solar thermal collectors and district heating.

Savosolar delivered 240 m² of collector area, which is used to cover 20–30% of the total thermal energy need of the building.

Guangzhou

Savosolar has been selected to deliver a tracker mounted solar thermal plant for the district heating of Nansha, Guanghzou, China. The system is combined with a geothermal seasonal storage and a chiller (not in Savosolar’s scope of supply) which allow the owner to deliver healthy energy, both heating and cooling, to its customers.

Mikkeli

Largest solar thermal plant in Finland

Savosolar has been selected as general contractor to build the largest solar thermal system in Finland to date, on behalf of Etelä Savon Energia Oy for its district heating network, which supplies households with healthy heating. The plant operate as an additional peak load sources during summer season while the main boilers are out of service.
