The aim of the project is to modernise the existing local heating supply and to expand it in the areas of the neighbouring community of Wolfach and the district of Oberwolfach Kirche. As a result, the path of renewable and sustainable energy production, which it embarked on as a pilot plant in 1995, is to be continued and expanded consistently. The existing heating network will be expanded towards Wolfach and Oberwolfach. The existing energy generation is replaced by modern wood heating, a highly efficient combined heat and power plant with heat pump and heat transfer from an external wooden boiler. As a result, the heat supply is almost entirely from renewable or sustainable energy generation plants.
