  • GC-heat supports and challenges. As part of a trainee project our apprentice team has independently established an internal startup. Thus, we were able to experience business administration in line with actual practice.

  • GC-heat is a reliable partner. In order to make my apprenticeship even more diverse, GC-heat cooperates with other companies from the region.

    Stuart G., Mechatronic trainee

  • GC-heat is a family business. My mother has been working for the company for many years. From the very beginning I've been an integral part of the team. Today I can optimally apply myself by taking on different tasks in my area of expertise.

    Maria K., Sales administration

  • GC-heat offers opportunities. After completing my apprenticeship, I am now studying part-time for my business degree with the support of GC-heat and gained valuable experience abroad in a project stay in Asia.

  • For GC-heat technology is not only man’s business. Already during my apprenticeship as a technical product designer I can support the technical development with a different way of thinking – both in product design as well as in construction.

Occasional training at GC-heat

Youth development is part of our corporate philosophy! For us, the training of young professionals and executives is a key factor with which the skills shortage and the challenges of a demographic shift can be sustainably addressed.

This is why a high-quality and practice-oriented vocational training is a central pillar of the GC-heat-HR strategy and therefore an important part of the corporate strategy.
Our goal is to develop technical skills within the own company and to permanently retain young performers within the company through highly attractive offers. Through this, both a sustained organic growth as well as a targeted knowledge transfer between generations can be ensured within the company.

Trainees at GC-heat can expect to be trained in all necessary company areas and that they will gain comprehensive insights into the entire GC-heat-world. Fundamentally, the vocational school days are work-free to ensure that the trainees can use the time to study. We also provide expert knowledge through internal training and educational events that are conducted in cooperation with experts in the respective work field.

Through this, trainees are provided with the optimal setting for their future - self-determined, comprehensive and with the best possible mentoring that we as an experienced company are able to offer. Therefore, it is no coincidence that GC-heat received several awards in recent years for its involvement in the training, from both the Chamber of Commerce as well as from the Federal Employment Agency.

Our goal with each trainee is to train the professionals of tomorrow in our own ranks and to subsequently transfer that trainee into our permanent staff. Of course for this, there are many important factors, such as the course of the training, the completion as well as number of open job positions.
