🔥 Why Do Water Heaters Last Anywhere from 8 to 20 Years?

Understanding the Factors — and How Angle Stop Plumbing Helps You Get the Most from Yours!

When it comes to home essentials, your water heater is one of the hardest working appliances in your house. It’s easy to overlook—until something goes wrong. But have you ever noticed how much the life expectancy of a water heater can vary? Some last just 8 years, while others keep on heating for nearly 20 plus years.

Let’s break down why that range is so wide, what affects your water heater’s life span, and how Angle Stop Plumbing can help you get every last year (and drop of hot water) out of yours.

🧰 1. The Type of Water Heater Matters

Not all water heaters are built the same.

• Traditional tank-style water heaters typically last 8–12 years on average if properly maintained.

• Tankless water heaters, which heat water on demand, can last 15–20 years or more when properly maintained.

  
  

The difference is in design — tank-style units constantly hold and reheat water, while tankless systems only heat water as you need it, reducing wear and tear.

💧 2. Water Quality Plays a Major Role

It might surprise you, but the quality of your water has a huge impact on how long your water heater lasts.

• Hard water (full of minerals like calcium and magnesium) leads to sediment buildup inside the tank, which can cause overheating and corrosion that will weaken the construction materials of water heater.

• Softened or filtered water helps minimize mineral deposits and internal stress, extending the unit’s lifespan.

  
  

That’s why Angle Stop Plumbing often recommends pairing your water heater with a water filtration or softener system — it protects your investment by reducing internal scaling and corrosion.

⚙️ 3. Maintenance Makes All the Difference

Regular maintenance can easily double the life of your water heater! Simple steps like:

• Flushing the tank annually or descaling a tankless to remove sediment buildup.

• Inspecting the anode rod, which protects the tank from rust.

• Checking safety valves and temperature settings.

These proactive steps prevent major breakdowns — and Angle Stop Plumbing can handle all of them for you through routine service appointments.

🌡️ 4. Usage & Installation Quality

Your water heater’s workload also affects its lifespan. Larger families (or high-demand households) cause more heating cycles per day, shortening its life. On top of that, proper installation matters. Poor venting, incorrect pressure settings, or mismatched supply lines can stress the system right from day one.

With Angle Stop Plumbing, every installation is done by trained pros who ensure your system runs efficiently and safely from the start.
