The answer to 'how long will water heater last' is that the average lifespan of a water heater is 8 to 12 years, with proper maintenance and care. Water heaters are essential home appliances that provide hot water for showers, laundry, and other household needs. However, their lifespan can vary depending on factors such as the type of water heater, the quality of installation, and the water quality in your area.
Gas-powered water heaters typically last 8 to 12 years, while electric water heaters can last 10 to 15 years. Tankless water heaters, which heat water on demand, can last up to 20 years with proper maintenance. Regular flushing and inspection of the water heater can help extend its lifespan, and it's important to replace the anode rod every 3-5 years to prevent corrosion. If your water heater is nearing the end of its lifespan or showing signs of wear, it's best to consult a professional HVAC technician to determine if it needs to be repaired or replaced.
