This study is to explore and analyze the system efficiency and pipe network heating loss of district heating plant of Shenyang, China. The study did actual measurement survey on heating supply of Shenyang's Wulihe plant from 2007 to 2008. The study is to survey the steam and heating water according to their differences in medium, and it also introduces the calculation method of pipe network heating loss in theory. Due to the fact that medium temperature in steam is higher than in water, so it has higher heat losses than heating water. The efficiency of a heat exchange in heating plant is 95% and the efficiency of a boiler is 74.8%. Fuel expense is the largest expense in terms of systematic operation cost, averaging 64%. Look into the future, if every house hold installs a valve to adjust temperature, not only it can help people to save energy but also to decrease any heating losses from unbalanced heating.
