The modules are: Order processing 2, thermodynamics 2, MSR 2, standard heating load / energy requirement; pressure loss calculations, hydraulics 2, heating technology 3, heating technology 4, application of law, financial and operational accounting, costing 2, financial management, business management, marketing, personnel management, networking module business management.

The continuing education, further training to become a master heating engineer with a federal diploma is completed by most schools in four semesters, i.e. two years, which corresponds to the study minimum.

The Advanced Federal Professional Examination (AFPE) for Master Heating Engineers with a Federal Diploma is not an examination in which you are tested on pure knowledge and tick the correct solution in a multiple choice procedure. Instead, you will work on a business management case study covering topics such as costing, accounting, law and business administration. In addition to this case study, you will also write a "heating installation" dissertation, which is prepared in advance and discussed in a technical discussion and presented orally in a presentation during the examination.
