摘　　要：以供应300m2左右用户采暖的燃气壁挂炉为例,利用热经济学方法对燃气壁挂炉的采暖和供生活热水系统进行了分析,得出不同天然气价格和采暖日平均运行时间下的平均输出成本.对影响平均输出成本的因素进行了敏感性分析,认为天然气价格是最主要的因素,其次为采暖日平均运行时间,燃气壁挂炉初投资费用的影响最小.In the paper, heating and domestic hot water system of wall-mounted gas boiler are analyzed by using thermal economy. A wall-mounted gas boiler for 300 m^2-house is selected, and the average output exergy cost is calculated according to different natural gas price and average heating time. The influence factors of the average output exergy cost are given sensitivity analysis,and natural gas price is the main influence factor, average heating time is the second factor, initial investment of wall-mounted gas boiler is the last factor.
