When was the last time you thought about your water heater? For most homeowners, the answer is “not until something goes wrong.” But knowing how long water heaters last—and how to help yours reach its maximum lifespan—can save you from unexpected cold showers, leaks, or even catastrophic water damage. Let us help you figure out how your water heater in Helena, MT is doing.
Typical Lifespans for Residential Water Heaters
Not all water heaters are built the same. The most common residential options are conventional tank water heaters (gas or electric) and tankless water heaters. On average, a traditional tank water heater lasts between 8 to 12 years, depending on usage, water quality, and maintenance. Gas models often trend toward the lower end of this range, while electric heaters can last a bit longer.
Tankless (on-demand) water heaters generally boast a longer life expectancy—up to 20 years—since they heat water only when needed and don’t store large amounts of water in a tank that can rust or corrode over time.
How to Make Your Water Heater Last Longer
A few simple steps can help your water heater reach or even exceed its expected lifespan. Regular professional maintenance is at the top of that list. Annual inspections allow a qualified plumber to catch minor issues before they become major problems.
For tank water heaters, periodic flushing is essential. Over time, sediment builds up inside the tank, which can cause corrosion, reduce efficiency, and put extra strain on the unit. Draining and flushing the tank annually helps remove this buildup.
Checking the anode rod is another crucial part of maintenance. This rod attracts corrosive elements in the water, preventing them from rusting the tank itself. If the anode rod is depleted, your tank could start to corrode from the inside out. Replacing it when needed can add years to your heater’s life.
Tankless water heaters need maintenance too. Hard water can cause mineral buildup inside the unit, affecting performance and longevity. Having a professional descale the system every year or two keeps it running efficiently.
Signs Your Water Heater Is Nearing the End
No water heater lasts forever. Be alert for warning signs that yours may be on its last leg:
- Rusty or discolored water: This can signal corrosion inside the tank.
- Strange noises: Rumbling or popping sounds often mean excessive sediment buildup.
- Leaks: Moisture or pooling water around the tank should never be ignored.
- Inconsistent or lukewarm water: If you’re not getting the hot water you need, it could be a sign the heating elements are failing.
The Dangers of Waiting Too Long
Putting off a replacement can lead to more than just cold showers. A failing tank water heater can rust through and burst, dumping dozens of gallons of water into your home. The resulting water damage can be costly and stressful—and entirely preventable with timely action.
