The topic of the diploma thesis is the operational efficiency of heat sources . The thesis is divided into three parts. In the first part a theoretical solution of the heat sources efficiency can be found. In the second part there is a calculation solution of the project. The project solves the heating of a football stadium. Two variants of the heating source and warm water preparation are suggested and the variants are consequently compared and evaluated. The last part is experimental - the topic of the experiment is the efficiency of heat sources.
