PURPOSE:To provide a substantial reduction of a resisting force and a heat transfer coefficient during a thermal medium transfer from a near heat source point to a thermal radiating point, further substantial reduction of a thermal medium transfer energy, a heat energy loss, a facility loss and a material cost and the like, and attain a substantial improvement of a thermal radiation efficiency at the thermal radiation location. CONSTITUTION:In a heating system for use in transferring heat energy from a near distance heat source, hot water containing salicylic alkaline metallic salt acting as anti-ion medium and steariltrimethyl ammonium of halogenide (for example, chlorine, bromine) acting as surface active agent by 100 to 500ppm is flowed in a thermal medium transfer pipe with a diameter of 10 to 75mm between the heat source point and the thermal radiation point under a Reynolds number of 10,000 to 40,000. In addition, the hot water described above is flowed at a Reynolds number of 40,000 or over at the thermal radiation point. |
