Preview of HEATEXPO 2025: Innovative solutions for sustainable heat supply
HEATEXPO 2025 is fast approaching – and will provide exciting answers to the pressing question of which approaches work best for sustainable heat supply. ENGIE Refrigeration will use numerous practical examples to demonstrate how energy-efficient cooling and heating solutions, and in particular sustainable concepts for district heating and waste heat utilisation, are already driving the heat transition forward today.
Hardly any other area of the energy transition is currently as much in focus as sustainable heat supply. New legal frameworks, increasing energy efficiency requirements and pressure to reduce CO₂ emissions are rapidly changing the industry. Those who want to keep up in the industry need sustainable, flexible and economically viable heating solutions. HEATEXPO offers the ideal platform in this field to show how innovative technologies and new approaches are actually accelerating the heating transition. Lectures, discussions and best practices make it clear that the future of heating has long since begun – and that it is full of opportunities.
Broadly positioned for sustainable heat supply
When it comes to suitable solutions for sustainable heat supply, ENGIE Refrigeration is at the forefront at HEATEXPO 2025. With a future-proof portfolio of industrial heating solutions, the cooling and heating specialist is responding to future scenarios in various industries efficiently and sustainably. From Spectrum Water heat pumps and thermeco2 high-temperature heat pumps to QUANTUM with Green Heat Recovery: ENGIE Refrigeration's products and concepts equip customers for the sustainable heat supply of tomorrow, whether in technical building equipment, in the field of production or in data centres.
Focus on district heating
One area of expertise is the efficient supply of cooling and heating networks. The team of cooling and heating specialists in France has successfully planned and implemented numerous district heating and cooling projects. In Bordeaux, for example, a Spectrum Water heat pump shines with its powerful heat output across a total building area of 40,000 square metres in an office and hotel complex. SPECTRUM uses geothermal energy as a heat source for sustainable heat supply and utilises waste heat when the heat pump is in cooling mode – topics that will also be featured at HEATEXPO. This heating solution scores particularly well in partial load conditions thanks to its high seasonal efficiency values (heating SCOP 45/55 up to 6.11; cooling SEER up to 8.26).
Using geothermal energy and heat recovery
Similarly, two QUANTUM Water chillers and two QUANTUM Power chillers in Marseille master district cooling and heating supply using seawater in combination with geothermal energy. And on a campus in Paris, where four QUANTUM water chillers and two QUANTUM water chillers with Green Heat Recovery (GHR) reliably provide district cooling and heating: one QUANTUM Water with GHR saves more than €20,000 in energy costs per year and 1,428 tons of CO2 compared to conventional energy generators.
From data centres to milk production
In addition to district cooling and heating in cities and neighbourhoods, ENGIE Refrigeration is contributing to sustainable heat supply in other industries. For example, the cooling and heating specialist is developing tailor-made concepts for waste heat utilisation in data centres. In ten Edge Data Centres in German metropolitan areas, three QUANTUM Air chillers make waste heat from the cooling process available to local interested parties. Furthermore, five SPECTRUM Water chillers in two modern new buildings belonging to a chemical and pharmaceutical company are demonstrating their potential for simultaneous heating and cooling. Geothermal energy is used as the energy source. ENGIE Refrigeration is also currently setting standards for sustainable process heating and cooling in the beverage industry with seven thermeco2 high-temperature heat pumps in a large dairy in northern Germany.
Don't miss our presentation at HEATEXPO
These application examples clearly show that there are many possibilities for sustainable heat supply. ENGIE Refrigeration impresses here with both a sophisticated portfolio of cooling and heating solutions and extensive expertise. Reinhard Jaki, Head of Sales Germany West, will share this expertise at HEATEXPO 2025 in his presentation "Into the future with ENGIE Refrigeration: Innovative concepts for sustainable heat supply and decarbonisation". All interested parties are cordially invited to attend on Thursday, 27 November 2025, at 13:50.
