In order for economically viable distributed generation systems for local community to spread, it is essential to develop an efficient and low-cost heat supply system. For this purpose, we are proposing a new heat supply system. The key technology for the system is to connect compact heat supply units with hot water heat storage tank installed in each house by a single loop hot water piping. It is expected that flow rate of hot water supply can be reduced by using distributed heat storage. The effect leads to reduction in pipe diameter, heat loss and pump power. In this study, to confirm the effect on leveling heat transfer rate through the main pipe, a dynamic simulator for heat supply system to 50 households was developed, and the effect of operation mode and capacity of distributed heat storage was evaluated.
