Introduction
Thank you for taking the time to read our article on how long water heaters last. This is a topic we receive a lot of questions about, and for good reason. Water heaters are a vital component of any home, providing us with hot water for showers, baths, and cleaning. However, they don’t last forever, and it’s important to know when it’s time to replace them.
That’s why we’ve put together this comprehensive guide on how long water heaters last, along with some advantages and disadvantages of various types of heaters. We’ve also included a table to give you an idea of the lifespan of different types of water heaters. So, without further ado, let’s dive in!
How Long Do Water Heaters Last?
Many factors can affect the lifespan of your water heater, including the type of heater, the quality of installation, usage patterns, and maintenance. On average, a typical tank-style water heater lasts between 8 and 12 years. However, some can last up to 20 years with proper maintenance and care.
Tankless water heaters have a longer lifespan and can last up to 20 years or more, depending on the quality of the unit and installation. Heat pump water heaters have a similar lifespan, as do solar water heaters. However, due to their complexity and specialized components, they may require more maintenance and repairs over their lifespan.
It’s important to keep in mind that as your water heater ages, it becomes less efficient and may require more frequent repairs. At some point, it will be more cost-effective to replace it with a new unit that is more energy-efficient.
Here are some factors that can affect the lifespan of your water heater:
Quality of Installation
The quality of installation can affect the lifespan of your water heater. If the installation is done incorrectly, it can cause premature failure of the unit. It’s essential to hire a licensed and reputable plumber to install your water heater to ensure that it’s done correctly.
Usage Patterns
The amount of hot water you use and how frequently you use it can affect the lifespan of your water heater. If you have a large family that uses a lot of hot water, your water heater will have to work harder, which can age the unit faster. If you use your water heater less frequently, it may last longer.
Maintenance
Regular maintenance can extend the lifespan of your water heater. Flushing the tank annually, checking the pressure relief valve, and replacing the anode rod can prevent sediment buildup and corrosion, which can cause premature failure. It’s also essential to call a professional plumber if you notice any issues with your heater.
