TECHNO-ECONOMIC ANALYSIS OF THE APPLIED HEAT SOURCES FOR HEATING ON THE EXAMPLE OF FAMILY HOUSE IN KRUSEVAC

Abstract

Households in Serbia have a significant share of energy consumption for heating, and there is an increasing trend towards the use of renewable energy. This paper deals with annual energy consumption for heating by using various heat sources on the example of the single family house in Krusevac. Heating systems, for which the analysis is done, are the electric boiler, gas condensing boiler, heat pump air - water, heat pump water - water, heat pump ground - water, firewood boiler and pellet boiler. The results showed that certain heating systems do not satisfy the requirements in terms of energy efficiency. The paper indicates the possibility of using devices with higher efficiency and utilization of thermal energy. Economic analysis was done as well, in order to show the most profitable solution of selection of heat source.
