严寒地区几种供暖方式的经济分析

Economic Analysis of Some Heat-Supply Ways in Cold Areas

通过对集中供热、燃气锅炉及电能供暖等多种供暖方式进行经济对比分析,得出了如下结论:系统的初投资以顶棚电热膜供暖为最高,电暖器供暖为最低;年运行费用以电热供暖为最高,集中供热为最低。

By analyzing economically the ways of heat- supply, centralized heat- supply, burning- gas boiler heat- supply and electrical power heat - supply, the passage concludes that of all the initial investment of system, the investment of heat - supply using electrical heating films in the ciling of the house is the highest and the investment of heat - supply using electrical equipment is the lowest; Yearly operation costs of the electric power heating system is the highest, and the costs of centraliged heat- supply system is the lowest.
