UHRIG Energy

References

UHRIG has already installed 120+ wastewater heat recovery systems in Europe, all of which continue to run reliably. The oldest system has been running smoothly for around 16 years. The use of wastewater heat is a proven, straightforward, efficient way to decarbonize the heat supply for buildings.

Below you will find information about selected projects. There are now numerous studies that describe the overall potential of wastewater as an energy source. The consensus is that in Germany alone, the heating demand of around 4 to 12 million people could be covered by wastewater heat.

An established, successful market participant

We have already realized about 120 major wastewater heating projects in Europe. Most of these are located in Germany, but also in France, Austria, Switzerland, Belgium, the Netherlands, Norway, and other countries. For the past two years, we have also been active in North America, where we established a subsidiary. Wastewater energy can be harnessed wherever there are people and a wastewater infrastructure.

Here is a small selection of our past projects. Please contact us if you would like to know more.
