According to Zhongguancun online query, improper use of gas water heater or equipment failure may lead to explosion, which may be caused by the following reasons:
1. air leakage: if the air tightness of the gas water heater is not up to standard, or misoperation occurs during use, it will lead to air leakage. At this time, if you encounter an open flame, it is easy to catch fire or explode.
2. The exhaust pipe is blocked: the gas water heater will discharge waste gas during use. If the exhaust pipe is blocked, more and more gas will be discharged, resulting in excessive internal pressure of the gas water heater, which may eventually lead to an explosion.
3. Thermal efficiency reduction: If the gas water heater is used for too long, it may lead to thermal efficiency reduction and gas consumption increase.
4. Serious scaling: The gas water heater has serious scaling, which slows down the heat exchange speed and may also lead to explosion.
