What's the matter with the sound of the gas water heater? Why does the gas water heater still ring without water?

Water heaters are a must-have household appliance in the home. There are many heating methods for water heaters, and the common ones are gas, solar and plug-in water heaters. If you have a gas water heater at home, you may find that the water heater will make a "clicking" sound after a period of time. If the heat preservation function is turned on, this is usually normal. Let's learn more about it together.

What is the reason for the sound of the gas water heater

The sound is the sound of the gas water heater running. Oxygen is needed for matter to burn, so gas water heaters heat cold water for a short period of time, which requires a lot of heat, which means constant replenishment of air. The fan is activated and continuously draws air into the combustion chamber. The rotation of the fan can cause the enclosure to resonate, resulting in mechanical noise. So when the gas water heater is running, there is a constant humming sound. The principle is actually a bit like a household electric fan. Remove the iron mesh outside the electric fan, there is no sound when idling, after installing the iron mesh, there will be a humming sound, which is the sound produced by resonance. In addition, the wind in winter is very strong, and the phenomenon of backflow is easy to occur. The fan needs to be faster to exhaust the exhaust. Then, the noise of the fan will become louder, and the speed of this forced rotation will increase. If it lasts for a long time, it is easy to damage the fan. Therefore, it is recommended that users choose variable frequency fans that many brands have, namely adaptive wind energy.

Why does the water heater beep every once in a while

This is because of the heat preservation function of the water heater. Because the thermostat will disconnect when the water heater is heated to the set temperature, and it will reheat when the water temperature is lower than the set temperature. At this time, it will automatically pull in and start the thermostat or relay inside, so it will emit intermittent The sound will beep again when the temperature reaches the disconnection, so it will beep every once in a while.

Why does the gas water heater make noise without water?

First, it may be because the hot and cold water is backflowing in the water pipe of the water heater. In this case, the hot water flowing through the cold water pipe will bring a certain water pressure and make a sound; it may also be because the gas of the water heater is leaking, so there will be a noise. Both of these reasons are very dangerous. Therefore, when you hear noise, you must ask someone to check your home in time.
