Water heater can be said to be an essential electrical appliance in the home, but there are many fire and poisoning accidents caused by the use of water heater in the society. Then, do you know how to effectively prevent explosion?
Cause of explosion of gas water heater
1. Poor product quality leads to gas escape, emission and leakage, and fire or explosion in case of fire;
2. The installation is unscientific, and the "compartment installation" is not really achieved;
3. The outdoor exhaust gas cannot be discharged in time without convection.
How to purchase and maintain
1. It must be a 3C certified product, which should be selected from the aspects of specification and model, water tightness, air tightness, hot water yield, ignition device and so on.
2. The installation must be carried out by professional technicians: the gas water heater shall not be installed in the toilet. It should be installed in a place with good ventilation environment. Smoke pipes and independent flue leading to the outside must be installed, and access to public flue is prohibited.
3. Regular maintenance of water heater: regularly check whether the rubber hose is aging, cracked and broken. Apply soap on the connection of gas pipeline. If there are bubbles, it is the air leakage part. Once found, replace it in time.
4. Pay attention to the service life: according to the regulations, the judgment life of artificial gas water heater is 6 years, and that of liquefied petroleum gas and natural gas water heater is 8 years.
Precautions for using water heater
1. The service life of the gas water heater is 8 years. The gas water heater exceeding the service life will be damaged in varying degrees in performance, and there are serious potential safety hazards. It should be replaced immediately when it expires;
2. When using the water heater, pay attention to keep good ventilation. Articles can not be hung on the air supply and exhaust port of the room, so as not to affect the air circulation;
3. In the process of use, the safety inspection of the water heater shall be carried out at regular intervals. In case of smoke leakage, blockage or backflow, please stop using it immediately;
4. After use, check whether the gas valve is closed, often check whether the gas supply pipeline is in good condition, pay attention to regularly replace the rubber hose, use soapy water to check whether there are bubbles at the hose connection, and report for repair in time in case of air leakage.
5. Replace the magnesium rod regularly. The magnesium rod used in the water storage electric water heater will accelerate its consumption in the heating process. Once the magnesium rod has problems, it is easy to cause safety accidents.
