Core Insights - Increasing number of old household appliances are being replaced, but many families continue to use gas stoves that have exceeded their service life, with some being used for over ten years. It is important to recognize that gas stoves have a defined lifespan and should be replaced when necessary [1] Group 1: Replacement Guidelines - Gas stoves and water heaters typically have a clear disposal age limit, generally not exceeding 8 years from the date of sale [3] - Signs that indicate a gas stove needs replacement include: - If the stove valve does not close properly, leading to frequent extinguishing of the flame - If the water heater's output fluctuates between hot and cold, professional maintenance should be sought, and if it remains unusable after repairs, replacement is necessary [6] - The normal flame color for gas stoves should be blue; if the flame is not blue, produces black smoke, or if a pungent odor is detected while using the water heater, immediate replacement is required [6] Group 2: Maintenance and Safety - Regular cleaning of gas stoves is essential as gas ports, nozzles, and burner caps can become clogged with grease over time, affecting normal combustion [9] - Gas connection hoses can deteriorate over time, leading to breakage or damage; regular inspections and the use of compliant hoses are recommended [9] - A stable gas usage environment is crucial; gas combustion consumes indoor oxygen, so proper ventilation must be maintained to prevent incomplete combustion or extinguishing of the flame [11]
