Different Heating Systems for Single Family House Energy and Economic Analysis

The existing building stock energy consumption accounts for about 38% of final energy consumption in Republic of Serbia. 70% of that energy is consumed by residential sector, mostly for space heating. This research is addressed to the single family house building placed in the Belgrade city. The house has ground and first floor with total heating area of 130 m2 and pellet as space heating source. The aim of this paper is to evaluate energy and economic analysis for different heating systems. Several homeheating were compared: Option 1 (biomass combustion boiler using pellet as a fuel), Option 2 (gas combustion boiler) and Option 3 (heat pump). The building performance was evaluated by TRNSYS 17 simulation code. Results show estimated savings using renewable energy sources. [Projekat Ministarstva nauke Republike Srbije, br. III42008]
