How Long Does a Water Heater Last?

Replacement of a Water Heater

The unsung heroes of your homes, water heaters discreetly provide you with the luxury of hot water for your everyday activities. You frequently take these items for granted, whether it’s a hot cup of morning coffee or a soothing shower. However, knowing how long a water heater lasts is important for budgeting as much as for practicalities.

In this blog, we’ll explore the several elements that affect water heater longevity, identify wear and tear indicators, and learn useful advice to guarantee your water heater continues to serve you well for many years to come.

The Lifespan of Water Heaters: How Long Can You Expect Yours to Last?

Types of Water Heater

Types of Water Heater 

  • Tank Water Heaters 

Tank water heaters are built with heating components and a storage tank that holds hot water until it is needed. It is the cheapest form of heater, having a big tank that can contain from 30 to 80 gallons of water, depending on the water heater’s capacity. Typically, these tanks are fueled by electricity or natural gas, while some models use liquid propane or oil.

While widespread and inexpensive, their lifespan is typically 8 to 12 years. Tank flushing and other regular maintenance procedures can help them last longer.

  • Solar Water Heater System

Harnessing the sun’s energy, a solar water heater consists of a collector and a storage tank. Environmentally friendly and cost-effective in sun-drenched areas, they boost the lifespan to 20 years. However, the collector can last even longer.

  • Heat Pumps Water Heater 

Utilizing heat transfer from the air or ground, these energy-efficient units can be less effective in colder climates. Ideal for homes with moderate hot water demands, they usually last around 6-10 years, with longevity influenced by the regional temperature.

  • Condensing Water Heaters

Capturing and utilizing the exhaust gases from gas heating, these highly energy-efficient units are suitable for homes with high hot water demand. Typically lasting from 6-10 years, their durability hinges on regular maintenance.

  • Power Vent Heaters 

Featuring a fan and a blower, the power vent heater provides flexibility in placement. With a lifespan of 10-12 years, regular maintenance and proper venting can contribute to their durability.

  • Tankless Water Heaters

These units deliver hot water instantly, bypassing the need for the storage tank. Renowned for their energy efficiency, they only heat water when necessary. With a lifespan of 20 years, their durability stems from a simplified design with fewer components prone to wear.

When to Replace Your Hot Water Heater 

Replace Your Hot Water Heater

Knowing when to replace your hot water heater is crucial to prevent unexpected breakdowns and water damage. Here are some signs indicating it might be time for a replacement:

  • Age

Tank-type water heaters typically last around 8 to 12 years, while tankless heaters can last 20 years or more. If your water heater is approaching or exceeding its expected lifespan, it’s wise to consider a replacement even if it’s still functioning.

  • Rust or Corrosion

Visible signs of rust on the tank or water connections suggest potential internal corrosion. It compromises the structural integrity and efficiency of the water heater, signaling a need for replacement.

  • Leaks

Any indication of water pooling around the base of the water heater or from its connections is a red flag. Leaks can lead to significant water damage and should prompt immediate consideration for replacement.

  • Strange Noises

Banging, popping, or rumbling sounds can indicate sediment buildup in the tank, reducing efficiency. If flushing the tank doesn’t resolve the issue, it can be a sign that the water heater is deteriorating internally and needs replacement.

  • Inconsistent Heating

If your water heater struggles to maintain a consistent temperature or takes longer to heat water, it could be a sign of a failing heating element or other internal components. In such cases, replacement will be more cost-effective than repairs.

  • Increased Energy Bills

A significant increase in energy bills without an apparent cause could indicate reduced efficiency in your water heater. As heaters age, they often become less efficient, prompting the consideration of a more energy-efficient replacement.

  • Frequent Repairs

If you find yourself frequently calling for repairs or experiencing recurrent issues, it will be more economical to invest in a new water heater rather than continually patching up an aging one.

  • Unusual Water Quality

Changes in water quality, such as rust-colored or foul-smelling water, can be attributed to a deteriorating water heater. If these issues persist despite flushing the tank, replacement is necessary.

  • Lack of Hot Water

If your water heater fails to provide enough hot water for your household, it may indicate that it is not capable of meeting your needs and requires replacement.

  • Safety Concerns 

Safety is paramount. If you notice signs of gas leaks, carbon monoxide leaks, or any other safety concerns, turn off the water heater immediately and seek professional assistance.

However, in this case, replacement is the safest option.

Average Replacement Cost of a Water Heater 

When it comes to the replacement cost of the water heater, various factors come into play, such as labor cost, material, and the size of the unit. Tank water heaters are the conventional type of water heater. They are less expensive to replace and install than other types of water heaters.

They can cost between $600 and $800; however, this depends on the size of the tank. The average cost of installing a tank-style water heater is between $900 and $2,500. Tankless heaters tend to be more energy-efficient but may require additional installations. Their installation costs range between $1000 and $3500.

Gas water heaters rely on natural gas or propane oil. Their installation cost can range between $500 and $2500. The cost of replacement varies depending on the size of the tank and the additional labor required. However, while gas models are less expensive to operate, they require an existing natural gas line to function.

Final Thoughts 

In the realm of comfort, the water heater stands as the silent guardian, ensuring your daily routine flows seamlessly. Knowing when to replace this indispensable appliance is pivotal to avoid potential damage and unexpected disruptions. Leaks, rusts, and diminished efficiency are indicators that the time might be ripe for the replacement.
