Green off-grid heat energy in multi-apartment building in Varena (Lithuania)

The renovation of a multi-apartment building in Varena to use a 100% renewable heat energy and hot water supply was completed in 2013. While the district heating system in Varena is already fired by biomass in proportions of 97%, the aim of the project was to prove that a 100% off-grid solution is possible as well. To cover the heating needs of the 40 apartments in the building from green sources, seven wells were drilled to a depth of 100m and connected to a heat pump, while hot water is now provided by solar collectors on the roof (http://co2mmunity.eu/green-heat-energy-in-lithuania).
