In this study; approximately 150 m2 of floor space Eskisehir-Turkey have been investigated in a 2- story home. The building is heated with natural gas and heat loss is 24;172 kW. 3000 m 3 / year to meet the heat loss and the cost of natural gas consumed in 1620 U.S. dollars / year. Only the heat pump system under study is replaced by natural gas boilers; home heating system has not been any other changes. Thermodynamic analysis is applied; first; both the system and exergy loss of energy expenditure were calculated. Second; the environmental values were calculated for both systems. Finally; the results were compared between the two systems.
