If you’ve ever wondered how long a hot water heater lasts, you’re not alone! A water heater is one of the most important home appliances, providing hot water for laundry, showers, and dishwashing. But just like any other appliance, a hot water heater has a limited life. Knowing when to replace your water heater can save you from cold showers and expensive repairs. Let’s discuss this in today’s blog.
What is the Average Life of a Water Heater?
The average lifespan of any hot water heater depends on type, usage, and maintenance. Traditional tank water heaters generally last 8 – 12 years, while tankless water heaters can sometimes last 20 years or even more. However, some elements can impact a water heater’s lifespan, including water quality, maintenance, and the type of fuel supply used.
Types of Water Heaters & Their Life
Let’s explore the different types of water heaters and the lifespans you can expect from each one! We are excited to discuss this in more detail with you.
Tank Water Heaters
A tank water heater stores and heats cold water continuously, so water is always available when needed. While convenient, these heaters experience sediment buildup, which can shorten their life. Over time, the tank can corrode, leading to water leaks and failure. Regular maintenance from professionals, flushing the tank , checking the anode rod, all these can extend the life of your water heater.
Tankless Water Heaters
Unlike tank water heaters, tankless water heaters heat cold water on demand! This means they do not store hot water! This reduces sediment buildup and corrosion risks. With fewer parts exposed to constant temperature changes, tankless heaters can last 20 plus years. However, mineral deposits from poor water quality can still cause damage, making routine maintenance by professionals necessary.
Gas Water Heater vs. Electric Water Heater
A gas water heater generally has a slightly shorter life than an electric water heater. This is due to its components. The heating water element in an electric water heater lasts longer because it doesn’t experience the same level of wear and tear as a gas burner. Fuel supply and Proper venting checks can help maximize the life of a gas water heater. Let’s now discuss some signs you need to replace your water heater.
Signs You Need to Replace Your Water Heater
Even with maintenance, a hot water heater will eventually need to be replaced. Here are some signs that it’s time to replace your water heater:
- If you notice water leaks around the water heater tank, it’s a clear sign of corrosion or a failing pressure relief valve.
- If rusty water comes from your taps, it could indicate corrosion inside the tank.
- If your water heater struggles to provide enough hot water, it is due to a failing heating element or a faulty thermostat.
- Banging or popping sounds suggest sediment buildup, which can cause overheating.
- If your water heater requires constant fixes, buying a new one might be more cost-effective.
How to Extend Your Water Heater’s Life?
Taking proactive steps can actually increase a water heater’s lifespan and improve its efficiency, too. Here’s how:
- Inspect the pressure relief valve to confirm it’s functioning properly.
- Flush the tank of your water heater annually to remove any sediment buildup.
- Check the anode rod every few years; replacing it can prevent tank corrosion.
- Install a thermal expansion tank to lower pressure on the water heater tank.
- Monitor the quality of water regularly, as hard water accelerates corrosion.
- Adjust water temperature to a safe setting ( generally around 120°F).
What Causes Water Heater Leaks & How to Fix Them
Several factors can cause a water heater leak, and fixing the issue on time will prevent serious water damage. One cause is a faulty pressure relief valve, which releases excess pressure if it’s not functioning. Another frequent culprit is sediment buildup at the bottom of your water heater tank! This can cause overheating and cracks in your water heater tank.
Corrosion, often caused by a failing anode rod, can also weaken the tank and cause leaks. If you notice water leaking around the unit, first check the heating element connections and the fuel supply. Small leaks may be fixable by replacing worn-out parts, but if the storage tank itself is damaged, you will need to replace your water heater. Regular maintenance from professionals, such as inspecting the thermal expansion tank, will prevent leaks and extend your water heater’s life.
Conclusion
So, how long does a hot water heater last? It depends on the type, professional maintenance, and water quality, but proper care can maximize its life. If you’re experiencing issues such as a faulty thermostat, a leaking water heater, or rusty water, it may be time to replace your water heater.
Be it a gas water heater, electric water heater, or tankless water heater, regular maintenance from professionals and timely replacements will keep your home’s hot water running for years to come. if you
