How to clean the natural gas water heater?

The appearance of gas water heater needs to be cleaned and wiped frequently. Most water heaters are installed on the balcony of kitchen and bathroom, which is easy to contact with dust and smoke. For a long time, dust and smoke have been directly attached to the shell of water heater, and it is difficult to clean after forming stubborn dirt, which affects the use of internal components, so interval treatment is needed. The method of cleaning the shell is relatively simple. Just wipe it with a rag regularly every week. If there is oil fume, you can wipe a little detergent on the rag to quickly remove the oil stain on it.

To clean the inside of the natural gas water heater, the shell must be disassembled for cleaning. The residual carbon in the burner should be cleaned with special carbon removal agent. First, put the decarbonization agent into the cleaning solution, then soak it for a period of time until the charcoal becomes soft, and then wipe it with a brush or rag. Clean with hot water after wiping. Don't use it after washing. Don't wash it. The internal structure of the water heater is complicated. It is recommended to contact the brand professional after-sales service guarantee. After preparing the tools and materials to be used, unplug the water heater, close the gas valve and water inlet valve to ensure that the water heater is in the state of water, electricity and gas cut-off, and do not start it when cleaning. Spray hot water or turn on the tap to drain water. Open the drain valve at the water inlet to drain the water in the water heater. Note here that some water heater drain valves may be at the drain, some water inlets are filters, and some are equipped with safety valves. As long as they are turned on, air can come in and drain all the water in the water heater.

After the water in the water heater is drained, we should inject the detergent into the water heater now. There are many methods, usually starting from the drain valve at the water inlet. You can use the injection method with special door design, connect a small pump, and use the simplest large syringe. The specific concentration of detergent is subject to the instructions of the detergent you bought, and the powder should be diluted in advance. When injecting cleaning agent, it is suggested that the warm water pipe should also be injected with cleaning agent until the whole hot water system and water heater are full. Pay attention to the water heater here, it is too general and the installation is relatively high. Our faucets, showers and water heaters are all high, and detergent will flow out. Therefore, we should take appropriate measures to prevent the leakage of detergent and fill the water heater. Specific methods, many methods, such as raising the water pipe a little and closing the valve in time. We talk too much.

Cleaning agent cannot be discharged immediately after injection. Detergents should react with water to dissolve. The specific soaking time depends on the concentration we use and the requirements of its description. It should also be noted that cleaning agents are generally acidic in water, and when they react with alkaline water, they also have a certain corrosive effect on metals. The interior of our water heater is generally a copper heat exchanger, which will also cause some corrosion, so the soaking time and the concentration of cleaning agent must be as required to prevent the water heater from corrosion.
