Course description: Course objectives:
Education of mechanical engineering students (thermal engineering) in the field of heating technology and heating systems design. A wide range of topics are dealt with in lectures and seminar format.

Enrolment requirements and required entry competences for the course:
Regular admission to the 6th semester of the study of mechanical engineering with appropriate number of the ECTS. Completed attendace to lectures in Thermodynamics 1, Thermodynamics 2, Fluid mechanics 1, Fluid mechanics 2.

Student responsibilities:
Attendance to lectures and excercises. Correct calculation of assignments in excercises.

Grading and evaluation of student work over the course of instruction and at a final exam:
Written exam 60%, oral exam 40%.

Methods of monitoring quality that ensure acquisition of exit competences:
Selfevaluation of the course and applied teaching methods.

Upon successful completion of the course, students will be able to (learning outcomes):
