This study aims to make a renewal scheme by analysis of two cases of central heating system for multiple dwelling house; CaseA is adequate capacity boiler system with two-position controlled and CaseB is over-capacity boiler system with proportionally controlled. Firstly, analysis of CaseA with cogeneration installed showed that the efficiency in the period of cogeneration working was higher than stopping. Secondly, analysis of two cases showed that CaseB is better in temperature
