HEATEXPO 2026
Edition3 Showcasing industrial heating, boilers, and thermal efficiency solutions, attracting German and European factory, utility, and engineering buyers.
HEATEXPO is an international specialized exhibition focused on innovative heating and cooling supply, held in Dortmund, Germany. Around the future of heating and cooling, decarbonization and the energy transition, it presents technologies and solutions that can be experienced on site.
The show brings together companies from equipment manufacturing, infrastructure services, consulting and energy supply. Around themes including the generation of heat and cold, infrastructure and distribution networks, digitalization, and development and investment, it covers the complete value chain from production and distribution to financing.
Displays and discussions target industry, municipal utilities, energy supply companies, the housing sector and local governments, addressing large heat pumps, district heating and cooling networks, thermal storage, digital heat control and municipal heat planning, and responding to the strategic, technical and regulatory issues raised by legislation such as the Building Energy Act and the Heat Planning Act.
Concurrent professional activities and networking sessions give exhibitors, visitors and industry professionals opportunities for in-depth dialogue and connection, making the show suitable for heating and cooling equipment, engineering services, consulting firms and energy suppliers.

Reduce demand first, then supply efficiently and cover demand with renewables, combined with funding and a smart step-by-step renovation plan.
The 2045 heat system will be a networked, largely fossil-free overall system linking buildings, the power market and infrastructure, based on electrification, environmental heat and system integration.
They should be planned as a coordinated heat-network system with low-temperature networks, stable base sources, large heat pumps, heat storage, load management and digital control.
Low-temperature heat networks distribute heat at lower flow temperatures than conventional systems, typically about 10-60°C, reducing losses and enabling better integration of renewables, ambient heat, waste heat and heat pumps.
