In fact, the choice of gas water heater capacity is not the bigger the better, but choose the actual capacity in line with their actual situation is the best, if you also have the need to buy gas water heaters, we must first understand the size of the gas water heater, the secret, The more you understand, the less likely it is to be confused. When you compare different products together, it is easy to choose products that suit you. Then Xiaobian also collects a lot of relevant information. Let's study together.

The size of a gas water heater actually refers to the maximum amount of hot water energy that can be heated in a unit of time. For example, 8L, the actual representative meaning is: this heater in the largest firepower, when the inlet temperature is specified as 25 degrees, the outlet temperature defaults to 45 degrees, its maximum output in one minute is 8L, In the same way, if it is 12L, it means that the water is also fed at 25 degrees and the water is discharged at 45 degrees. The maximum water output per minute is 12L.

1, first consider should be selected according to the type of gas used. Each type of gas appliance has a logo for the type of gas appliance. It is necessary to purchase the same type of gas as the gas used in your home. At present, there are mainly three kinds of gas sources in China: natural gas, liquefied petroleum gas, and artificial gas. The design of the water heater is determined based on the characteristics of the gas source. Because the three gas source components are different, the dimensions of the burners and other components designed and manufactured are also different. A water heater is generally only suitable for a gas source, recognize the signs: artificial gas JSR, liquefied petroleum gas JSY, natural gas JST, to prevent mistakes.

2, the use of pipeline gas users. In the purchase of gas water heaters, to ensure that the gas water heater gas consumption is not greater than the flow of gas meter at home, the use of steel cylinders liquefied petroleum gas users please select the appropriate pressure reducing valve, otherwise it will result in insufficient gas supply, can not fully play water heater The ability to supply hot water.

3, to buy gas water heaters, to consider whether the safety device is complete and reliable, such as flameout protection, water overpressure protection, anti-dry safety protection, antifreeze protection. It is recommended to choose the mode with intelligent anti-freeze function instead of the anti-freeze method of releasing water manually through the drain valve.

4, water heater water output per minute is very small, so the water heater has 6 liters, 8 liters, 10 liters and other specifications of the points. Large-flow water heaters are suitable for households with large populations and no heating, while small-flow water heaters are the opposite. If you live above the fifth floor, it is best to choose a gas water heater that starts with a low pressure.

5, at least to choose strong exhaust gas water heater. The discharge method of ordinary flue gas water heater exhaust gas requires high installation, and most residents are not installed according to the specifications. However, the flue gas of a strong exhaust gas water heater can easily meet regulatory requirements. For ease of operation, products with large-screen backlit LCD windows and digital touch buttons are also a good choice. In the internal configuration, the more advanced on the market is the use of electronic proportional valve, intelligent adjustment of combustion power, while the configuration of the machine with stepless frequency strong blower, can maximize the combustion efficiency, save gas. In order to make the constant temperature effect better, high-precision electronic water temperature and water flow sensors and other devices are also important. The heat exchangers that are relatively high on the market today are environmentally friendly oxygen-free copper heat exchangers, which have higher heat exchange efficiency and longer life. In terms of safety performance that consumers are concerned about, a full-security self-checking system with a microcomputer should be selected. If the product can be configured with a very compact digital line controller, and the operator on the machine can also be removed and installed as a line controller in the bathroom, it should be a masterpiece of the strong row of products.

6, it is recommended to choose forced balance, although the price is high, but better security. The water heater of this type passes through the double coaxial flue pipe, and the air required for combustion is forcibly drawn from the outside, and the exhaust gas is forcibly discharged to the outside, and there is no possibility that the exhaust gas leaks out of the room, and no indoor air is consumed. In addition, due to the use of a double flue pipe, when the air from the outside enters the machine, the hot exhaust gas that is exhausted to the outside is pre-heated, which has the effect of recovering energy. Some top brands have built-in microcomputer control of high-performance smart chips

Xiao Bian suggested: For the average family, the southern climate is warmer, water heater heat load (similar power) requirements are lower, from an economic point of view, choose a water heater below 8 liters can meet the requirements of comfortable bath; and the northern region The average water temperature of tap water is low, especially in winter showers, which require high heat load (similar power) of the water heater, so the family in the north recommends that the choice of 8 to 10 liters is appropriate. However, if the user has a large home area and has multiple bathing rooms and only wants to install a water heater to supply hot water, it is recommended to select a gas water heater with 13 liters or more and a constant temperature water supply function.
