How to choose a household gas water heater? What are the precautions for using a gas water heater?

For household gas water heaters, the gas source is the main factor that determines its use, so when purchasing, you must pay attention to identifying the form of its gas source, and then purchase it based on the actual situation of the family. Of course, its safety and after-sales service are also factors that we should focus on. Let's take a look at how to choose!

How to choose a household gas water heater

1. Check the gas source: For household gas water heaters, the gas source is the main factor that determines its use. At present, the gas sources of gas water heaters mainly include artificial gas and liquefied petroleum gas, but the two are not interchangeable, so when purchasing, you must pay attention to identifying the form of the gas source, and then purchase it based on the actual situation of the family.

2. Exhaust gas emission device: There are many potential safety hazards for water heaters, and one of the key factors is the emission of exhaust gas. For gas water heaters currently on the market, there are two main types of exhaust gas emission devices: flue exhaust type and forced exhaust type. The flue exhaust type mainly uses the exhaust pipe to connect the exhaust port of the water heater to discharge exhaust gas, so if the flue is not installed properly, it will cause exhaust gas backflow and cause danger; the forced exhaust type mainly relies on installing a small fan on the water heater body, and starting the fan through the linkage device of the water heater to discharge the exhaust gas. This type of exhaust method is less affected by natural factors and is safer.

3. After-sales service: An important consideration when buying a water heater is the after-sales service. Unlike other household items, gas water heaters have many safety hazards, so after purchase, they are generally handed over to professional technicians for installation. Therefore, when purchasing a water heater, you must pay attention to the manufacturer's after-sales service, whether there is a local maintenance point or a special maintenance department, so that it will be more convenient and time-saving to repair it when problems occur in the future.

What are the precautions for using gas water heaters?

1. When using a gas water heater, be sure to read its instruction manual carefully. The specifications of each gas water heater are different, so the usage process is also different.

2. When using a gas water heater, its pipes must be made of metal pipes, not rubber pipes, to prevent accidents caused by hot water spraying out of the bowl due to aging.

3. After use, you should regularly check the gas water heater's piping system for problems. It is best to clean the filter inside regularly and apply soap foam on the pipe to check for cracks, aging, looseness, etc.

What is the fault of gas water heater E0?

Electric leakage. If the gas water heater displays e0, it indicates electric leakage. The specific situation can be divided into leakage protection function and ground wire live indication.

1. Leakage protection function: When the temperature bar of the water heater shows "E0" flashing, the buzzer keeps beeping, the heater does not work, and all button operations are invalid, it indicates that there may be leakage in the current circuit; the leakage protection function is implemented by grounding wire, anti-electricity wall, and built-in leakage protection coil.

2. Indication of ground wire power: When the red indicator light on the right side of the water heater panel is on, and the temperature bar displays "E0" flashing, the buzzer sounds continuously, the heater does not work, and all button operations are invalid, it indicates that the current ground wire is powered or there is a power failure. At this time, you should immediately stop using the water heater and unplug the power plug, and ask professional maintenance personnel to repair it.

Do I need to turn off the gas valve after using the gas water heater?

Yes. The structure of the gas water heater is complex. It relies on a water-gas linkage valve or a thermoelectric solenoid valve to close the pipeline. It has low reliability and is prone to leakage. After leakage, the gas will be deposited inside the water heater. In addition, due to the poor temperature, humidity and ventilation environment in the bathroom, the rubber pipe is prone to aging and cracking. Once it leaks, an accident is very likely to occur. Therefore, the gas valve should be closed in time after use.
