An 8-kilometer pipeline is being built to supply geothermal heat to the city of Burghausen from the Kirchweidach-Halsbach facility in Bavaria, Germany.
The city of Burghausen in Bavaria, Germany has signed a geothermal heat supply agreement with Naturwärme Kirchweidach-Halsbach, marking a major step toward expanding its district heating network. The agreement includes the construction of an eight-kilometer pipeline, which will deliver sustainable geothermal heat from the Halsbach plant to Burghausen, the largest city in the Altötting district with approximately 19,500 residents.
Kirchweidach is the site of a geothermal project that produces electricity and supplies heat to the local community and a greenhouse operator, we have reported on before.
Expanding the Geothermal Network
Burghausen’s district heating system will undergo significant expansion in the coming years, beginning with the integration of the existing network in Burghauser Neustadt. The project aims to connect more residential and commercial properties to renewable geothermal energy, reducing reliance on fossil fuels and lowering CO2 emissions.
Background: Naturwärme Kirchweidach-Halsbach
The Naturwärme Kirchweidach-Halsbach initiative was founded as a joint project between the municipality of Kirchweidach and the company Gemüsebau Steiner. Initially, the geothermal plant in Halsbach was developed to provide sustainable heating to Kirchweidach and Steiner’s greenhouse operations.
However, due to the high thermal output of the well, surplus heat is now being made available to additional municipalities and businesses in the region. Recognizing the potential of geothermal district heating, Burghausen—through its energy subsidiary EBG (Energieversorgung Burghausen)—has taken the opportunity to integrate geothermal energy into its local heating infrastructure.
Project Timeline & Implementation
- Letter of Intent Signed – City officials and Naturwärme Kirchweidach-Halsbach representatives have formally agreed to build the pipeline and supply geothermal heat.
- Construction Start (2026) – The pipeline from Halsbach to Burghausen is expected to begin construction in 2026.
- Phased Expansion – Initially, an existing district heating system in Burghauser Neustadt will be connected, followed by a gradual rollout of a new district heating network across the city.
This expansion will enable thousands of residential units and businesses to switch to renewable geothermal heat, significantly reducing carbon emissions and strengthening regional energy independence.
With growing investment in geothermal district heating, Germany continues to advance sustainable energy solutions at the local level.
