Exhibitor voices



  • ” HEATEXPO has established itself as an outstanding event that has been extremely well received. The excellent target group approach is particularly positive: municipal utilities and energy suppliers are fully represented, which makes the trade fair an ideal place for exchange and networking. We are delighted to be part of this platform and can look back on very successful discussions and many new contacts.”

    Stephan Höflmaier, Head of Business Development, Bilfiger Industrial Services GmbH



  • “We have been regular exhibitors at HEATEXPO since the beginning. The continuous development of the trade fair is reflected in the consistently high quality of the discussions. The topics relating to large heat pumps and decarbonization are particularly exciting. For us, this is a clear focus that perfectly matches our solutions.”

    Dr. Klaus Ramming, Head of the Thermotechnology Division, AGO GmbH



  • “The market for the heating transition is developing rapidly. In just three years, HEATEXPO has achieved the status of a leading trade fair and has become indispensable for us. We were particularly proud to present the 2G Afilia-water-isobutane series for the first time on this platform – a pioneering product premiere that puts us one step ahead in heat transition technology and meets current market needs. The show has established itself as a positive example of how to develop an event properly.”

    Sigurd Schiller, Sales engineer heat pumps, 2G Energietechnik GmbH
