What is the standard height of the water heater?
Especially in September 26, 2010 jointly issued the national quality supervision and inspection and quarantine and the national standardized management committee No. GB25127.2-2010 "low temperature air source heat pump (water environment)" in the national standard units, cold vigorously promote the members of the unit, with the February 1, 2011 implementation of the air distress requires strict quality standard of low ambient temperature long run industry.
In order to regulate the industry standard, 2008, 2009, the state continued introduction and implementation of the GB/T21362-2008 "commercial or industrial use and similar heat pump water heater" commercial aircraft and GB/T "national standards for household and similar use of heat pump water heater" national standard household machine.The standard uniform of the domestic air heaters can test conditions and methods and commercial water heater system, and the provisions of the prescribed standards of environmental conditions, the energy efficiency ratio of not less than 3.4 of cop, cyclic heating energy efficiency ratio of not less than 3.7 cop.
The standard 1. of water heater in our country redefines the structure of gas water heater, and the classification of structure is very different from before. Straight row water heaters require large amounts of oxygen because of the burning process. The CO and CO2 can cause harm to the human body, and sometimes even endanger life. Since 2000, the state has banned the production of straight water heaters. From this point of view, the standard for straight rows has been removed from the standard. In the new standard, the gas water heater is redefined, divided into three types: flue type, strong platoon type and balanced type. 2., to add new technologies, new processes, the main increase is the gas water heater electrical control part. The previous gas water heater was simply a gas appliance. With the development of science and technology, gas water heater in the technical use of the many electrical control components, automatic control, electrical safety, intelligent remote control, remote strong ventilation, so that the water heater function more perfect. Some provisions were added to ensure the safety of the product. 3., the new water heater products are mainly heating type and heating water type. A new standard of the new water heater products in recent years, increasing the structure, performance requirements and test methods for heating and heating water heating dual-purpose type water heater, and simplify the re enactment of the drawing method of product model, and gives the schematic diagram. While standardizing existing mature technologies, there is room for new and emerging technologies.
