At the meeting, experts said the current situation of our country's water heating system, water is the main carrier of heat medium system, water treatment and control of direct impact on the operation of heating system, involving thousands of households. Research and development of heating the water quality standards is urgently needed now, "industrial boiler water quality standards" is the emphasis on the requirements of the boiler; the "closed cycle cooling water standards" do not fully meet the needs of heating water; existing heating network design (CJJ34-2002) in only makes provision for additional water quality, while the network is running hot water not required. Therefore recommended the heating system for heating the actual need for a national water quality standards required to enable the heating system terminal equipment can follow the use and research to improve the safety of heating. Refuse to use those particular bad water as water heating heat medium. At present, China for heating water and central heating system of the second network part for the water quality there is no standard, resulting in extensive management operation mode, the system operation costs are high, unstable conditions and other issues. New products, new technology implementation has also brought great negative impact. Such as: the application of the current nationwide household heat metering encountered many problems, poor water quality is the main problem; all kinds of new and efficient promotion of the radiator due to corrosion and because water quality problems, difficulties. Therefore, the formulation of water quality standards is the industry's urgent need for heating over the years.
