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.

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.

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.

Voreppe

Veolia, a global corporation with focus on transport, waste, water and energy built and operate a new district heating network for the city of Voreppe, France.

For this solar installation, the space available for collectors was limited to a structure in midair between two buildings. Having a high solar yield was important criteria. Consequently, Veolia chose the well-designed Savosolar solution and its Savo 15 DG flat plate collectors being the most efficient in the market.

This installation in Voreppe was Savosolar’s first turn-key delivery for district heating in France. It raised interest among the district heating sector showing the potential of solar thermal as a clean heat production.
