Gammel Engineering and Stadtwerke Traureut have been working together since 2002. A biomass cogeneration plant supplies a large number of public, commercial and private properties with heat.
In 2010, the integration of the geothermal power plant built by a private investor into the overall network was investigated - and a favorable heat supply contract was successfully negotiated for Stadtwerke Traureut.
Last Friday, the district heating feed-in from geothermal energy was put into operation in Traunreut. This means that over 2000 households in Traunreut can now be supplied with geothermal energy.
Every second, 40 liters of thermal water are extracted from a depth of 5000 meters - the target is 165 liters per second. After the energy transformation, this thermal water is then fed back into the water reservoir; two heat exchangers ensure trouble-free heat transformation into the district heating network.

Our employees voted together and decided to support the Hölzgen family with a donation from the Gammel Family Social Fund.
The exchange on digitalization, AI and new technologies is becoming increasingly important for companies. We are therefore all the more pleased that our authorized signatory Thomas Winkler will also be supporting these topics in the digitalization committee of the Regensburg Chamber of Industry and Commerce in future.
On 12.05.2026, Gammel Engineering was once again a guest at the Waltl-Hof for the annual asparagus dinner. In a relaxed atmosphere, with excellent food and good conversation, the focus was on one thing above all: spending time together as a team.
