Your water heater is an essential part of your home, providing hot water for bathing, cleaning, cooking, and more. But like any major appliance, it won’t last forever. Many homeowners wonder, “How long should my water heater last?” and “When should I replace vs. repair it?”
Understanding the average lifespan of water heaters, the factors that affect longevity, and the signs of a failing unit can help you make informed decisions about maintenance, repair, and replacement.
At Beehive Plumbing, we specialize in water heater repair, maintenance, and installation to ensure your home or business always has reliable hot water. This guide will help you determine when it’s time to repair or replace your water heater and how to extend its lifespan.
Average Lifespan of Water Heaters
Water heaters don’t last forever, but the type of system you have plays a big role in how long you can expect it to function efficiently.
Traditional Tank Water Heaters
- Average lifespan: 8 to 12 years
- Common issues:
- Sediment buildup reducing efficiency.
- Rust and corrosion inside the tank.
- Leaks from the base of the unit.
Tankless Water Heaters
- Average lifespan: 20 to 25 years
- Why they last longer:
- No standing water reduces corrosion risks.
- On-demand heating system means less wear and tear.
- More energy-efficient compared to traditional tank heaters.
Key Takeaway: If your tank water heater is approaching 10+ years old, or your tankless unit is nearing 20 years, it may be time to consider replacement options.

Factors That Affect the Lifespan of a Water Heater
While a water heater’s expected lifespan is important, several factors determine how long your specific unit will last.
1. Water Quality & Hard Water
- Utah has hard water, which means high mineral content (calcium and magnesium) can cause sediment buildup in water heaters.
- Over time, these minerals settle at the bottom of the tank, leading to reduced efficiency, overheating, and possible leaks.
2. Frequency of Use
- A household of 4+ people will use more hot water than a single-person household, leading to faster wear and tear.
- Frequent use increases strain on the heating elements and tank.
3. Maintenance & Routine Flushing
- Annual flushing helps remove sediment from tank water heaters, extending their lifespan.
- Regular anode rod replacement prevents corrosion inside the tank.
- Routine professional inspections help catch small issues before they become major problems.
4. Type of Water Heater & Installation Quality
- Tankless water heaters typically last twice as long as traditional models.
- Poor installation can reduce efficiency and increase the risk of breakdowns.
Beehive Plumbing’s Tip: Investing in routine maintenance and water softening systems can extend the lifespan of your water heater.
Signs It’s Time to Replace Your Water Heater
Even with proper maintenance, water heaters eventually wear out. Here are the top signs that indicate your water heater may need to be replaced.
1. Your Water Heater Is Over 10 Years Old
- If your tank water heater is 10+ years old, it’s nearing the end of its lifespan.
- Tankless units may last longer, but after 15 years, you should monitor performance closely.
2. Rusty or Discolored Water
- Rust-colored water from the hot water tap is a sign that the inside of your tank is corroding.
- A failing anode rod can no longer protect the tank from rust buildup.
- If rust is visible, replacement is recommended to avoid leaks.
3. Strange Noises Coming from the Tank
- Popping, cracking, or rumbling sounds indicate sediment buildup, which can cause overheating.
- Excessive sediment buildup reduces efficiency and can lead to tank failure.
4. Frequent Leaks or Moisture Around the Base
- Water pooling around the base of the heater suggests internal damage.
- Even small leaks can quickly escalate into major flooding.
5. Rising Energy Bills
- Older water heaters require more energy to heat water, increasing monthly utility costs.
- A new, energy-efficient model can reduce energy consumption and lower costs.
When to Repair vs. Replace Your Water Heater
When a Repair Is Enough
- Your water heater is less than 8 years old.
- The problem is minor, such as a thermostat or heating element failure.
- There is no major rust, corrosion, or leaks.
- The repair cost is significantly less than half the price of a new unit.
When It’s Time to Replace
- Your unit is 10+ years old and frequently breaking down.
- You notice rusty water, leaks, or excessive noise.
- Your energy bills are increasing due to inefficiency.
- Repairs are becoming too costly or ineffective.
