A Finnish district heating company Elenia Lämpö Oy invested in Savosolar solar thermal system to produce CO2-free energy for their customer, which in this case is a nursing home located in Hämeenlinna. The heat is used for domestic hot water and pool heating.
The installation is the biggest operational solar thermal system in Finland.
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.
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.

Bad Rappenau, Germany (largest flat plate collector plant in Germany)
Summa Energy has been selected as general contractor to build a +20 MW solar thermal system on behalf of Bauer Holzenergie GmbH for its district heating network, which supplies households and an industrial process for drying fruits with healthy heating. Only about 1,800 pieces of Savo 16S large scale high performance flat plate collectors are sufficient to getting combined with an 8,000 m³ heat storage tank and
provide 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.
