How Long Does a Water Heater Last? What You Need to Know

Water heaters are absolutely essential for providing hot water for daily activities, from bathing to cleaning to cooking. But like any appliance, water heaters have a lifespan, and eventually, water heaters fail. Understanding how long a water heater lasts and recognizing signs of wear can help you plan and avoid unexpected disruptions.

How Long Does a Water Heater Last?

On average, traditional tank water heaters last between 8 to 12 years, depending on the quality of the unit, water system quality, and maintenance. Tankless water heaters tend to have a longer lifespan of about 20 years or more because they don’t store water, which reduces wear and tear.

Several factors can affect the longevity of your water heater:

• Water Quality: Hard water can cause sediment buildup in the tank, leading to corrosion and decreased efficiency.
• Usage: Heavier use can wear down the system faster.
• Maintenance: Neglecting routine maintenance can shorten the heater’s service life.

How to Extend the Life of Your Water Heater?

Some effective tips to keep your unit running efficiently for as long as possible include:

• Flush the Tank Regularly: Water heater maintenance includes flushing the tank once a year to remove sediment deposits from the bottom of the tank.
• Check the Anode Rod: Inspect the anode rod every few years and replace it when it wears out.
• Inspect the Heating Elements: Electric water heaters have heating elements that can wear out before the tank does. Check these annually and replace as needed using the tank’s serial number to get the correct replacements.
• Maintain Proper Water Pressure: Install a pressure regulator to keep the water supply pressure within a safe range and prevent damaging your water heater.
• Install a Water Softener: If where you live has hard water, installing a water softener will reduce mineral buildup.
• Schedule Professional Inspections: Annual inspections by a professional plumber can help catch minor issues before they turn into costly repairs. They will also check your pressure relief valve to ensure it works properly.
• Insulate the Tank and Pipes: Insulating your water heater tank and water pipes helps reduce heat loss, improve energy efficiency, and reduce strain on the system.

Signs It Is Time to Replace Your Water Heater

Here are key indicators that it may be time to replace your water heater:

• Age of the Unit: If your traditional tank water heater is over 10 years old or your tankless unit is over 20, it may be nearing the end of its lifespan.
• Rusty or Discolored Water: If you notice rusty or murky water coming from your taps, it means corrosion is inside the tank and it’s nearing the end of its life expectancy.
• Unusual Noises: Banging, popping, or rumbling sounds coming from your water heater from excessive sediment buildup.
• Leaks Around the Tank: Any visible water pooling around the water heater’s base indicates a leak, which often means the tank has cracked or rusted through.
• Inconsistent Hot Water: If you’re frequently running out of hot water or the water temperature fluctuates, the unit may no longer be functioning correctly.
• Higher Energy Bills: As efficiency declines, energy bills will increase, indicating that your water heater’s life is almost over.
