Thermo-economic analysis of air sourced heat pump versus condensing boiler in different climate conditions

Due to environmental changes, energy consumptions' policies are needed to be more strict than past. Clean and efficent energy usage gain much more importance and governments start putting regulations to push both residential and industrial sectors to use high technology products to heat/cool /vantilate the closed areas. Heat pumps are one of the brand new technology which can lower harmful outcomes from residential/industrial heating to the environment with effective energy usage. Air Source Heat Pumps are the most popular heat pump systems, in use, in these days due to low installation costs and environmental friendly way of heating. In this paper, five cities –Budapest, Ankara, Istanbul, Izmir and Erzurum, are compared according to weather conditions (since ASHP-Air Source Heat Pumps'efficiency depends on outdoor temperature directly) if it is efficient enough to use the ASHP or not. For doing this, The Heat Pump system is compared with using condensing boiler in same conditions. For this case study, the heat demand of 99 m2 apartment is calculated and COP values of the ASHP is collected from one of the well-known heating manufacturer. Also economical perspective of the usage of ASHP is discussed by considering the initial costs of the products and are calculated return on investment.
