How Long Should a Water Heater Last?

Water heaters provide homes with hot water for daily needs, from cooking and cleaning to those relaxing showers after a long day. Most homeowners don’t think about this essential appliance until it’s no longer working as expected.

You might be wondering how long this appliance actually lasts. Join us as we delve into its life expectancy, the factors that influence their longevity, and tips to ensure you get the most out of your investment.

Understanding the average lifespan of water heaters

The average lifespan of a traditional tank water heater is typically between 8 to 12 years, whereas tankless models can last upward of 20 years with proper maintenance. However, several factors can impact longevity, including:

Water quality: Hard water is high in minerals and can lead to sediment buildup in the tank, affecting efficiency and reducing life expectancy
Maintenance frequency: Regular maintenance, including flushing the tank to remove sediment, inspecting the pressure relief valve, and checking the anode rod, helps extend the heater’s life
Installation quality: A unit that’s properly installed according to manufacturer specifications will generally have a longer service life
Usage demand: The more hot water your household consumes, the harder your unit works, which can contribute to faster wear and tear

Specific life expectancies for different types of water heaters are as follows:

Tank water heaters: Electric models usually last 8-10 years. Gas models can last 8-12 years
Tankless water heaters: Often have a lifespan extending beyond 20 years, attributed to having fewer mechanical components and a lower tendency for corrosion
Heat pump water heaters: Often last about 10-15 years, combining the technology of tank storage with efficient heating mechanisms
Solar water heaters: Have the potential to last 20 years plus, dependent on the climate and quality of the unit

These estimations assume routine maintenance and optimal conditions. Being proactive with your unit’s upkeep can not only prolong its life but also enhance its efficiency and performance over the years.

Essential maintenance tips to prolong your water heater’s life

Ensuring your unit enjoys a long and functional life doesn’t have to be complex or time-consuming.

Here’s how you can add years to your unit:

Annual inspections: Schedule a yearly check-up with a certified technician. This helps identify any potential issues before they become bigger problems
Regular flushing: At least once a year, flush the tank to remove sediment. This task is essential for preventing corrosion and inefficiency
Test the pressure relief valve: Safety first! Testing the pressure relief valve (PRV) can avert potential overpressure issues. Turn the valve on and off to tell if it’s working correctly—it should release a burst of water into the overflow drain pipe
Adjust the temperature: Set your unit to the right temperature—120 degrees Fahrenheit is typically recommended—to prevent overheating and reduce energy consumption
Insulate older units: For extra efficiency and to reduce heat loss, wrap older tank models in an insulating blanket. Just make sure not to cover any warning labels, valves, or caps
Replace the anode rod: The anode rod attracts corrosive elements in your water. It’s usually made of magnesium or aluminum around a steel core and should be checked every three years and replaced when it’s worn out

Remember, regular upkeep is not just about prolonging your unit’s life but also about ensuring its efficient and safe operation. Should you have any inquiries, or if you’re ready to schedule that maintenance visit, don’t hesitate to reach out to us at Plumb-Tech!

Making the decision between a repair vs. replacement

When you’re faced with water heater troubles, the age-old question emerges: repair or replace? It’s not just about cost; it’s also about efficiency and long-term benefits. Here’s a quick guideline to help you make a cost-effective decision:

Repair if

The unit is still within its typical lifespan and has had a history of reliable performance
The issue is minor, such as a replaceable thermostat, a pressure relief valve, or a heating element, and the costs are relatively low
The water heater still operates efficiently, and warranty coverage may offset repair costs

Replace if

The water heater has reached the end of its typical lifespan, particularly if repairs are becoming more frequent and costly
A major component has failed, such as the tank itself (where leaks and strange noises could be a sign of tank failure), which is more expensive than replacing the whole unit
The unit no longer performs efficiently or does not meet your household’s hot water demands
Upgrading could provide energy savings and newer technology, particularly if your current unit is not ENERGY STAR rated

Long-term thinking is key.

If you’re leaning towards a new water heater installation, here are replacement guidelines to consider:

Choose a model with an ENERGY STAR rating to ensure energy efficiency and cost savings in the long run
Consider the fuel type, availability, and cost, as these factors will affect the unit’s operational cost
Size appropriately; too large or too small of a unit for your household can lead to inefficiency and elevated costs
Look into newer technologies like tankless, heat pumps, or solar water heaters, which might offer longer lifespans and lower running costs
