How Long Does a Water Heater Last in Los Angeles?
The lifespan of a water heater in Los Angeles depends on the type of unit, water quality, maintenance history, and water pressure. Here is what Los Angeles homeowners need to know about water heater life expectancy.
Tank Water Heater Lifespan
A standard tank water heater — 40 or 50 gallon gas or electric — typically lasts 8 to 12 years in Los Angeles. LA’s hard water with high mineral content accelerates sediment buildup inside the tank, reducing efficiency and shortening the lifespan compared to areas with softer water. High water pressure, which is common in many LA neighborhoods, also stresses the tank and pressure relief valve over time.
Tankless Water Heater Lifespan
A properly maintained tankless water heater typically lasts 20 years or more — significantly longer than a tank unit. Tankless units heat water on demand rather than maintaining a standing tank, which eliminates the tank corrosion that eventually fails traditional units. Annual descaling maintenance is recommended in LA due to the hard water.
Signs Your Water Heater Needs Replacement
Your water heater needs replacement if it is more than 10 years old and showing problems, if you hear popping or rumbling sounds from sediment buildup, if the water is rusty or discolored from the hot tap, if there is water pooling under the unit, or if the pilot light keeps going out repeatedly despite thermocouple replacement.
