GEA is aiding Lemgo’s pursuit of climate neutrality by 2035 through the provision of two heat pumps. Utilizing GEA’s innovative technology, heat will be extracted from multiple sources, including the effluent of the city’s wastewater treatment plant, waste heat from a large combined heat and power (CHP) plant, and from the River Bega.
The heat produced by these advanced heat pumps will be utilized to supply the historic city center of Lemgo with environmentally friendly heat to the greatest extent possible. Notably, the heat derived from the wastewater treatment plant’s effluent alone has the capacity to fulfill two-thirds of the old town’s heating needs or twelve percent of the total demand of the district heating network. To optimize the benefits, the heat pumps are designed to operate continuously for up to 7,500 hours per year.
Furthermore, there is a target for renewable sources to account for more than 55 percent of the district heating required by 2028, further emphasizing Lemgo’s commitment to sustainable energy solutions
