The current winter is getting colder and colder, especially in the south. Without heating, winter is very sad, and the snow is getting bigger and bigger. How can we lose the gas water heater in such a cold season? With the water heater, the water will be It is very convenient, especially when hot water is needed in cold weather. Without a gas water heater, hot water cannot be supplied. However, when purchasing a gas water heater, many people are still laymen and do not know how to choose the right one. Let’s take a look at how to choose a gas water heater water heater.
Water heaters are installed in many homes. But at the time of selection, I don’t know much about water heaters, especially how to choose a gas water heater at all, and I don’t know what kind of water heater is suitable for my home. Let’s introduce the key points of purchasing a gas water heater.
1. The first consideration should be to choose according to the type of gas used. Each gas appliance has the identification of the type of gas appliance that is applicable, so be sure to choose the same type of gas as the gas used in your home. At present, there are three main sources of gas in my country: natural gas, liquefied petroleum gas, and artificial gas. When designing a water heater, it is determined according to the characteristics of the gas source. Because the factors of the three gas sources are different, the dimensions of the designed and manufactured burners and other components are also different. A type of water heater can only be used for one type of gas source in general. When choosing a gas water heater, customers should ask professionals for clarification and choose a water heater that is compatible with the gas source. Recognize the signs: artificial gas JSR, liquefied petroleum gas JSY, natural gas JST, in case of mistake.
2. Users who use pipeline gas supply. When purchasing a gas water heater, it is necessary to ensure that the gas consumption of the gas water heater is not greater than the flow rate of the gas meter at home. Users who use cylinder liquefied petroleum gas should choose the corresponding pressure reducing valve, otherwise the supply of gas will be insufficient and cannot be fully implemented. Expand the hot water supply capacity of the water heater.
3. Choose cheap gas water heaters carefully. There are many gas water heaters on the market that cost eight or nine hundred yuan or even lower. In fact, if the burner, fan, air valve, water valve, ignition system, control panel and the body itself are only used with ordinary quality materials, the cost will be more than 1,000 yuan. It seems that it is not wise to blindly try to be cheap choose. At the same time, we must pay attention to purchasing products that the manufacturer has after-sales service in the local area.
4. When purchasing a gas water heater, you must consider whether the safety device is intact. Reliable, such as flameout protection, water overpressure protection, anti-dry safety protection, antifreeze protection, etc. It is recommended to choose the method with intelligent antifreeze function instead of the antifreeze method of manually draining water through the drain valve. In the past few years, gas water heaters in many households did not have an intelligent antifreeze function. The machine would be frozen and leaked due to the lack of manual water release after bathing. In severe cases, the floor would be damaged, causing unnecessary losses.
5. The water output per minute of the water heater varies from large to small. Therefore, water heaters are divided into specifications such as 6 liters, 8 liters, and 10 liters. Large-flow water heaters are suitable for families with a large population and no heating, while small-flow water heaters are the opposite. If you live in a high-rise above the fifth floor, it is best to choose a gas water heater that starts with low water pressure.
6. At least choose a forced exhaust gas water heater. Ordinary flue gas water heaters have high installation requirements for the exhaust gas discharge method, and most residents have not installed them according to the specifications. The flue of the forced exhaust gas water heater is easy to meet the specification requirements. For ease of operation, a product with a large backlit LCD window and digital touch buttons is also a good choice. In terms of internal settings, the more advanced ones on the market now use electronic proportional valves to intelligently adjust the combustion power, and at the same time set up a machine with stepless frequency conversion strong blower, which can maximize combustion efficiency and save gas. In order to make the constant temperature effect better, devices such as high-precision electronic water temperature and water flow sensors are also very important. The best heat exchanger on the market now is an environmentally friendly oxygen-free copper heat exchanger, which has higher heat exchange efficiency and longer life. In terms of safety performance, which consumers are very concerned about, they should choose a whole-process safety self-inspection system with a microcomputer. If the product can be equipped with a very delicate and compact digital wire controller, and the operator on the machine can also be removed and installed in the bathroom as a wire controller, it should be a masterpiece among strong row products.
The above introductions on how to choose a gas water heater are very detailed. Now that there are more and more water heaters on the market, it will lead consumers to choose blindly. Everyone must refer to the above when purchasing a water heater How many points can you choose the most suitable water heater, especially the one with good quality and reputation.
