Recently, an increasing interest in district heating system has emerged rapidly, In this paper, the physical measurements and data to be monitoring through the internet were carried out with regard to hot water heating energy consumption at the three apartment housings with district heating system in Sang-am district of Seoul, Korea, Measurements were made of the thermal factors such as the pressure of heating pipe, flow rates, hot water temperature and etc, The objective of this study is to compare the design capacity of reheat exchanger with that of preheat exchanger in order to evaluate for the number of plates of two exchangers to be distributed properly.

The energy consumption in apartment houses is investigated according to the heating systems, that is, district, central, and individual heating systems. And, operating conditions of intermittent heating are surveryed and analysed in the central heating systems. As a result, each annual energy consumption of district, central and individual heating system is 143.56 Mcal/m2year, 216.78 Mcal/m2year and 150.68 Mcal/m2year, Also, the heating is generlly started at 04:00 and 17:00 of each day, and the heating system is operated for 2~3 hours per each time.
