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.
Løgumkloster Fjernvarme is a district heating company which annually supplies 35,000 MWh of heat to over 1,500 customers. Heat is produced with a hybrid heating system consisting of a 3 MW pellet boiler, a 1.3 MW hybrid heatpump, a 3 MW absorption heat pump and a solar collector field of 15,300 m2. Additionally, the plant has two gas engines which are capable of producing 7.6 MW of heat and 6 MW of electricity and a 10 MW gas boiler which acts as back-up.
In 2015, Savosolar delivered a 9,700 m2 solar thermal field to Løgumkloster. The second order of 5,600 m2 was delivered and commissioned in the beginning of 2016. The complete field consists of 1030 Savo 15 SG collectors and covers about 20% of the annual thermal energy need of the district heating network. The largest part of the heat demand is covered by the pellet boiler, but Løgumkloster Fjernvarme has plans to change this in the future by extending the solar field and building a large seasonal water storage.

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.
