It not only efficiently makes use of the various lowenergy to achieve energy saving, but also provides the well-distributed room temperature ,good sanitation, comfort and so on. So it is a ideal heating system that reduces the consumption of energy and raises the thermal comfort. This paper is a design of the low temperature water floor panel heating system. First, this paper analyzes the present conditions, advantages, disadvantages, the features in heat transfer and tubing. We can reach a conclusion that this system is comfortable. Second, it calculates the heat load of the housing building. Since room temperature exceeds the designed temperature of floor panel heating, the author reduce the temperature in room when calculate, in order to save energy. In aspect of the laying tubing, this paper adopts the double spiral of concrete embedded plastic radiant floor heating. The method can achieve a smooth floor surface to creat comfortable environment. Last, the heat meter and thermostatic radiator valve are fixed in the every house to control the temperature and to calculate heat metering. To sum up, the low temperature water radiant floor heating is an ancient, new heating system, which can provide comfortable and achieve energy saving. Key words: floor heating system;
