Özet

This research analyses the environmental impacts of domestic heat pumps with gas boilers and scenario analysis through a life cycle approach. The study analyses three scenarios (Transport (SK), 50% Hybrid and 75% Hybrid) to compare their results with a baseline model and also CE 2050 model which has a future outlook. The results show that changing the manufacturing location from Europe to South Korea doesn’t have a significant impact on both models as the weight of manufacturing and transport phases are relatively small compared to the use phase. Hybrid scenario results show increases in GHG emissions; however, the remaining categories have reductions. 50% Hybrid scenario results expect a reduction of 18% and 12% on average in ASHP and GSHP respectively in the baseline model. However, 75% Hybrid scenario results offer less reduction than the half-hybrid scenario in the same model with 8% and 5% decrease in ASHP and GSHP. In CE 2050 model, the results expect an increase of 27% and 21% on average in both heat pumps for 50% Hybrid scenario.On the other hand, CE 2050 model results offer less increase than the half-hybrid scenario for 75% Hybrid scenario with 18% and 13% increase in ASHP and GSHP respectively.
