The real value of heat energy is obtained by a qualitative or exergy analysis of its conversion, transport and distribution. The exergy value of heat or its capability of performing work can be a sound basis for the formation of a fair purchase price. The paper presents the fundamental laws which have to be known in order to describe the exergy conditions in a heating system. An analysis of the »Šalelška dolina« district-heating system is made. The parameters necessary for the determination of the thermodynamic conditions are gathered at each important point. For all the main branches of the system, exergy losses are calculated as a consequence of heat transport and distribution at a constant temperature of the environment. The analysis of the influence of the heat temperature level shows a strong exergy loss dependence on the temperature of supply and return and mass flow of water related to the temperature level. Considering also the temperature dependence of additional heat losses in the heat transport pipeline, the analysis shows that the temperature level is one of the most important factors for rational operation of the heating system. The performed thermodynamic analysis represents the basis for a differentiated tariff regulation which will, in addition to the quantity, also consider the temperature level of the consumed energy.
