What began in 2009 with an initial study is now a supra-regional showcase project for ecological district heating: together with Stadtwerke Kelheim, the team for decentralized energy systems from Gammel Engineering was able to accompany and play a key role in the strategic and technical development of the Kelheim district heating network over many years.
A networked overall system was created step by step from individual heating islands.
The heart of the system is a highly efficient wood-fired CHP plant with modern ORC technology. It is supplemented by buffer storage, peak load boilers and intelligent integration of existing infrastructures. The result: a secure, economical and legally compliant supply - always coordinated with the strong team at Stadtwerke.
Whether new heating plants, the reliable connection of sensitive consumers such as the district hospital or the grammar school or, most recently, the highly symbolic buffer storage tank - every step of the project stands for a clear vision, technical precision and trusting cooperation.
Kelheim shows how municipal heat supply can work today: sustainable, economical and jointly planned. We are proud to have been able to help shape this path for more than 15 years.

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.
