Abstract: In order to compare the performance of heating devices under different climatic conditions,the energy consumption,economic and environmental performance models were established. Four kindsof heating devices were analyzed,including CO2 transcritical air source heat pump ( ASHP CO2 ) ,R410A air source heat pump ( ASHP R410A) ,gas wall hanging furnace ( WGH) and electric heatingheater ( DEH) . The results show that ASHP CO2 has the lower energy consumption,which is 81.2% low-er than that of DEH. ASHP R410A and WGH have better economy,and their minimum total operatingcosts are 60% and 52.1% lower than that of DEH. WGH has the best environmental performance,fol-lowed by ASHP CO2 The PM2.5 emission of ASHP CO2 in Shanghai is 75.2% lower than that of DEH. Theenergy consumption,operation costs and pollutant emissions of the four heating devices reduce with thedecrease of regional latitude in all the typical cities except Changsha. The energy consumption ofASHP CO2 in Shanghai is 64% lower than that in Harbin. The total operating cost of ASHP R410A in Shang-hai for 15 years is 41% less than that in Harbin. The SO2,NOx and PM2.5 emissions of WGH in Shang-hai are 17.4%,34.3% and 34.3% lower that those in Beijing,respectively. The four devices rankedfrom best to worst comprehensive performance are WGH,ASHP R410A,ASHP CO2 and DEH. WGH is suit-able for cold regions such as Harbin. ASHP R410A can be used in other regions. The comprehensive indexof ASHP CO2 in Xi'an is higher than that in other cities. Close-
