7 Common Water Heater Questions We Get Asked

Buzzell • December 19, 2024

Your water heater plays a vital role in your daily life, whether it’s for hot showers, clean dishes, or laundry. But when something goes wrong—or when you’re thinking about upgrading—questions about how they work, how to maintain them, or what to expect from a new system often arise. At Buzzell Plumbing, Heating, and Air, we’ve heard it all. Here are seven of the most common water heater questions we get and our expert answers to guide you.


1. How Long Does a Water Heater Last?


The typical lifespan of a water heater is around 8–12 years for traditional tank models and up to 20 years for tankless water heaters. Regular maintenance, such as flushing the tank and replacing the anode rod, can help extend its life.


2. Why Is My Water Heater Making Strange Noises?


If you hear banging, popping, or rumbling sounds, sediment buildup in the tank is likely the culprit. Over time, minerals from hard water settle at the bottom of the tank, causing noises as the burner heats the sediment. Flushing your tank annually can prevent this.


3. What Are the Signs My Water Heater Needs to Be Replaced?


Key indicators that it’s time for a replacement include:


  • Rusty Water: Corrosion inside the tank can lead to discolored water.
  • Leaks: Water pooling around your tank signals structural damage.
  • Inconsistent Temperature: Fluctuations in hot water can mean your system is failing.
  • Age: If your water heater is over a decade old, it’s time to start considering an upgrade.


4. Which is Better: Tank or Tankless Water Heaters?


Both options have pros and cons:


  • Traditional Tank Water Heaters: These store hot water and are ideal for homes with higher simultaneous water usage. They’re generally less expensive upfront but cost more to run.
  • Tankless Water Heaters: These heat water on demand, offering energy efficiency and a longer lifespan. They cost more initially but save money over time.


Our team can help you choose the best system based on your household’s size, water usage, and budget.


5. How Can I Make My Water Heater More Energy-Efficient?


To improve your water heater’s efficiency:


  • Lower the thermostat to 120°F to reduce energy use.
  • Insulate your water heater tank and pipes to prevent heat loss.
  • Schedule regular maintenance to address any issues early.
  • Consider upgrading to an ENERGY STAR-certified model.


6. Why Am I Running Out of Hot Water So Quickly?


This could happen for several reasons:


  • Sediment Buildup: Reduces the tank’s capacity to store hot water.
  • Heating Element Issues: Electric models have two elements, and if one fails, it reduces the heater's performance.
  • Tank Size: Your household may need a larger water heater or a tankless system to meet demand.


7. Can I Install a Water Heater Myself?


While some DIYers might feel confident tackling this, installing a water heater involves electrical work, plumbing, and adherence to local codes. Improper installation can result in leaks, poor performance, or even safety hazards. Trust a professional, like our team at Buzzell Plumbing, for a seamless and safe installation.
