A Cost Analysis of Wall-Hung Mounted Gas Boiler Using in Residential Buildings of Beijing

In order to improve the city environment, and achieve a leap in making reasonable use of natural gas and optimizing energy structure, the Beijing municipal government has established its basic policy to “transform its coal-based energy structure, introduce large amount of natural gas”. As the wall-hung gas boiler has easy operation, flexible adjustment and high energy efficiency, the application of it is becoming more widely considered among the residential building. The work proposes the survey of the heating way about affordable housing and the “two limit” commodity housing in Beijing. The adaptability between the household wall-hung gas boiler heating way and other heating ways is compared. The energy efficiency, initial investment and operating cost of all the heating ways that are being used in Beijing are discussed in the paper. The final analysis is then evaluated by a panel of experts to determine its accuracy and potential for use in a greenway development plan of heating way in Beijing. Analysis shows that the commercial housing is more suitable than affordable housing to use the wall-hung gas boiler. This is mainly be effected by the characteristics of the user’s economic condition and the residences’ distribution.
