The history of Heiza

Over the past five decades, the family-run business Heiza has developed into a globally leading provider in field of thermal oil systems. Since its establishment in the mid-1960s, we have constantly grown in terms of our tasks and the needs of our customers.

An important step was taken in 2014 with the take-over of Werkstätten Apparate- und Anlagenbau GmbH for the establishment of HEIZA-WERKSTÄTTEN Wärmetechnik GmbH.

With experience, innovative ideas and the commitment of our staff, we will also ensure great progress in heat transfer and heat recovery in the future.
