District heating

Narbonne

With this new solar thermal plant for newHeat, Savosolar add a new leading reference in the French market of solar district heating. This approximately 3,000 m2 solar thermal field (aperture), will allow to replace 2,410 MWh of former gas heated heat by renewable heat on Narbonne’s city network, manage by a subsidary of Dalkia.

Savosolar, on the behalf of newHeat, built mainly the whole solar plant, from the solar collector’s field until the outlet of the heat exchanger to the storage thermal tank, ie: solar field, piping and solar station. More then 200 of our Savo 15 SG-M collectors, ensuring a high energy yield while reducing 510 tons of CO2 emissions per year from the district heating system of the city. The production of solar field during winter will even allow an increasing of the yield of the existing biomass boiler.

Savosolar delivered -once again- the largest solar thermal installation in Finland. This system is located way North in Tupos, Liminka – less than 200 km from the Arctic Circle.

The heating load of Tupos district heating is usually covered by wood pellets. Yet during summer time, the load is often so low, that the substantial wood pellet burner cannot be properly used and an oil burner got used, instead. The special challenge here has been to design a very efficient solar thermal system that could replace the oil consumption in summer to run the district heating network almost completely fossil-free.

Kherson

Savosolar’s first commercial solar cooling system was delivered to a school in Ukraine. The entire school was pre-fabricated in Finland and delivered to Ukraine by Elemenco Oy.

Outside of the cooling period, the solar thermal system produces energy for domestic hot water and space heating needs. During the hot summer time, three adsorption chillers cool the building via the air handling unit. The adsorption chillers, which were delivered by Savosolar, are driven by the solar thermal system.

Grenaa Varmeværk

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.
