Through in-depth analysis of the advantages,disadvantages,and applicability of hot water mechanical circulation systems and self regulating electric heating systems,and based on dif-ferent residential unit types,this study comprehensively explores the initial investment and opera-tional energy consumption of using hot water circulation systems and self regulating electric heating systems in residential units under different usage conditions.On this basis,taking the ratio of resi-dential gas prices to residential electricity prices in major cities in China as a reference,the operat-ing costs of mechanical circulation systems and self regulating electric heating systems for residen-tial hot water systems under different price ratios were obtained.The results showed that in cities where the ratio of gas prices to electricity prices was less than 4,the operating costs of electric heating systems were higher than those of mechanical circulation systems;Cities with a ratio of 4 to 4.5 have similar operating costs;Cities with a ratio greater than 4.5 have higher operating costs for mechanical circulation systems than electric heating systems.
