Summer has to, for now, is water heater products to enter the sales season, but because the fuel gas water heater of fuel gas appliances usually placed in space is airtight kitchen in the space, there could be enough oxygen and make the gas combustion is not full, cause gas poisoning phenomenon. There are now have active protection type enterprise launched prevent gas poisoning water heater burning gas. City disappear is protected appoint warn, this kind of gas water heater of choose and buy and installation are all important.
Water heater burning gas water heater as important in a category by quite a number of consumer welcome. But because the gas water heater of fuel gas appliances usually placed in space is airtight kitchen in the space, there could be enough oxygen and make the gas combustion is not full, which is colorless, odorless and poisonous gases carbon monoxide (CO), cause "carbon monoxide poisoning" (which is also often say "gas poisoning"), many consumers concerned about it. To ensure that consumers' personal safety. Now, there is active protection type enterprise launched to prevent carbon monoxide poisoning gas water heaters.
According to information, active protection type gas water heater working principle is to have "carbon monoxide safe protection system", when the alarm module monitoring inside the bedroom (not just to its own gas water heater, still can rise to monitoring the role of kitchen burning gas) carbon monoxide concentrations rose to dangerous value, the water heater is instruction alarm module began to sound and light alarm immediately cut off gas valve, host, and at the same time the water heater fan exhaust device to starting compulsory exhaust ventilation, will indoor carbon monoxide fast to take a platoon to outside. Objectively speaking, active protection type gas water heater increased consumer person property safety coefficient.
Active protection type gas water heater is good, but if the choose and buy and installation problems, not only won't improve security, may also bring use inconvenience or the losses of lives and property. To this, the annual warn broad customer pay attention to choose the mainstream of safe and reliable brand product. At present the brand of gas water heater is various, but have the capacity to produce active protection type gas water heater product enterprise is still limited. Some workshop the factory of carbon monoxide sensor sensitivity is not high, components position is not reasonable, carbon monoxide active protection function difficult to achieve. Consumer is when the choose and buy should pay attention to choose the mainstream of safe and reliable brand product. For active protection type gas water heater "carbon monoxide safe protection system" to meet the installation "separation installation" and a "high" characteristics of monitoring. Because kitchen burning gas also can produce "carbon monoxide (CO)" characteristics, warning module with water heater to host "separation installation" so that more completely for monitoring. At the same time, because of "carbon monoxide (CO)" characteristics (quality lighter than air, easily suspended in roof), alarm module "monitoring" high can monitor the more accurate. In addition, the national construction ministry promulgated "< household gas combustion appliance installation and acceptance procedures > implementation manual" requirement alarm module should be installed in the roof 30 CM from within and CO gas easily the stranded position.
Water heater burning gas extended use will have a lot of safety problems. According to our country "household gas fuel appliances safety management regulation" (GB17905-1999), household pipeline gas water heater service life is 6 years, liquefied natural gas and natural gas water heater for 8 years. State regulations from 1 May 2000 banned the sale of bath with give expulsion-typely gas water heater. According to use life calculation, in 2008, in the hands of the domestic consumer direct drainage water heater burning gas that should change. Consumers should be eliminated ZhongZhi row house gas water heater and other overterm service gas water heaters.
