Indicate the selection of solar water heaters in the country issued in March
According to the China Association for Quality Promotion survey, nearly Qicheng solar water heaters in winter there are security risks, more than 50% of the solar water heater can not meet consumer demand, consumer dissatisfaction focused on the water heater easy to freeze plugging, leakage, and poor collection efficiency, caused an important factor in these problems is water heater material shoddy.
However, this situation will be standardized and improved. National Standardization Technical Committee Secretary-General Jia Tieying Solar today in an interview that "the main components of domestic solar hot water system selection of general technical conditions" has the approval and is expected to formally promulgated in March next year.
It is reported that China s annual production of solar water heaters 23 million square meters, annual production of more than 76% of the world. However, the selection of the main components has been no uniform national standards, resulting in mixed selection of solar water heaters, some manufacturers do not provide consumers with rigorous testing of piping and fittings, a large number of risk products into the market.
China s solar thermal Committee Luo Zhentao that must be guaranteed by the material life of the product specification, reliability and stability. By the China Institute of Standardization and Wong Ming Group jointly drafted the "domestic solar hot water system selection of the main components of general technical conditions" through the validation, not only safeguard the interests of consumers, but also enhance the technological level of the solar industry, and promote the industry healthy development.
Jia Tieying said, according to national planning, the next two years will have 15 thermal aspects of the national standards, including spare parts, technical and engineering aspects of solar water heating systems will be gradually developed, introduced. Currently, the National Standardization Committee and other agencies are developing solar water heater "limits and evaluation of energy efficiency rating" mandatory national standards.
