At present, the water heaters on the market are generally divided into electric water heaters and gas water heaters, among which there are more families who choose gas water heaters
So what are the skills and concerns for the purchase of gas water heaters? What are the precautions in the usual use process? Let's learn from the city supervisor today
The quality and safety identification methods of gas water heaters have similarities with the quality and safety identification methods of many other products. Generally, it is carried out by checking the CCC certification mark, checking the product nameplate and identification information, checking the appearance and internal structure of the product, and understanding the product performance and safety devices. The identification of gas water heaters also needs to pay attention to one point, that is, it is forbidden to buy specific types of products.
1. Check the CCC certification mark The household gas rapid water heater product is a product that was included in the compulsory product certification (CCC certification) catalog in October 2019. When purchasing, be sure to check whether the product has the CCC certification mark. This marking is usually located on the product's nameplate or in a conspicuous location on the outer body. We can further verify the enterprise information and certified model of the product through the national certification and accreditation information public service platform to ensure that the purchased products are qualified products produced through formal channels.

2. Check the product nameplate and identification informationEach household gas rapid water heater should be installed in the appropriate position nameplate, the nameplate should include the name and model of the product, gas type or code, rated gas pressure, rated heat load, applicable water pressure, rated hot water capacity, rated voltage and power supply nature of the symbol, rated electric power or rated current, manufacturer name and other information. If the product does not have identification information or the information is incomplete, please do not buy and use it, as this may mean that the product has quality problems or safety hazards.
3. Prohibition of the purchase of specific types of products The former State Bureau of Light Industry and the former State Administration of Domestic Trade issued the "Notice on Prohibiting the Production and Sales of Inline Gas Water Heaters for Baths" in 1999, which stipulates that from October 1, 1999, the production of inline gas water heaters for baths is prohibited, and warning labels must be affixed to the products for non-bath inline gas water heaters, indicating that the product is prohibited from being used for bathing. Since May 1, 2000, the sale of in-line gas water heaters for baths has been prohibited. In addition, from March 2022, the certificates for flue gas water heaters have been cancelled all. Therefore, when you find a flue gas water heater in the market, please do not buy it and report it to the relevant authorities.
What are the mainstream gas water heaters on the market?
● Strong exhaust gas water heater. This is the mainstream type on the market right now and is suitable for most households. During operation, the exhaust gas generated by it is discharged to the outside, but the oxygen required for combustion comes from the room, so it needs to be installed in a well-ventilated location such as a kitchen and a balcony. ● Balanced gas water heater. The oxygen required for operation comes from the outside, and the exhaust gases are also vented to the outside, so it can be installed in a relatively enclosed space such as a toilet or bathroom. However, the price of this type of product is generally high, and the installation conditions are limited. ● Outdoor gas water heater. It can be installed outdoors to save space.
4. Check the appearance and internal structure of the product, and the outer surface of the barrel should be smooth and tidy, free of oil stains, and there should be no obvious scratches or bruises. Each sticker should be correct and neat. The foaming layer inside the product shall not have overflow, coarse holes, foaming and foaming, and the inner tank shall be clean and free of residual foam and other sundries.
5. Understand the product performance and safety deviceThe higher the energy efficiency ratio of the gas water heater, the more gas can be saved, and it also means that the performance of the product is more superior. In addition, the product should choose a gas water heater with multiple safety protection devices such as flameout protection, over-temperature protection, anti-dry burning protection, and anti-leakage protection to ensure that the gas source or power supply can be quickly cut off in the event of an accident to prevent accidents.
Finally, it should be emphasized that you should choose formal channels to purchase and keep the proof of purchase. When purchasing, be sure to ask for and properly keep shopping receipts and other shopping vouchers as a basis for future maintenance and rights protection.
In addition to the need to pay attention when purchasing, you should also pay attention to the following matters when using gas water heaters
