4. Answers to users’ high-frequency questions
1.Is buzzing dangerous?
Most of the cases are mechanical vibrations, but persistent abnormal noise may indicate component damage, and timely maintenance is recommended.
2.The reason why the noise is more noticeable at night?
Environmental noise is reduced at night, and water pressure changes more significantly when water consumption decreases, leading to prominent resonance phenomena.
3.What should I do if my new water heater makes abnormal noise?
Contact after-sales service immediately. It may involve improper installation or product quality problems. You can request a return or exchange within 7 days.
5. Preventive maintenance suggestions
• Professional deep cleaning every 2 years
• Install a pressure reducing valve (required when water pressure is >0.6MPa)
• If not used for a long time, the water stored in the tank should be emptied.
• Choose newer models with silent certification
According to the latest data from the Home Appliances Association, correct maintenance can extend the service life of a water heater by 3-5 years. If you encounter persistent abnormal noise problems, it is recommended to contact the brand’s after-sales service first to avoid dismantling it yourself and voiding the warranty.
