Why Water Heaters Fail

Why Water Heaters Fail

Imagine waking up on a chilly morning, eagerly anticipating a warm shower, only to be greeted by icy water. The frustration of a malfunctioning water heater is a common experience many of us have faced. Water heaters, like any other mechanical devices, are susceptible to failure over time due to a variety of factors. In this blog, we’ll delve into why water heaters fail and how you can prolong their lifespan.

**1. Age:

Just like any other appliance, water heaters have a finite lifespan. On average, a traditional tank water heater can last anywhere from 8 to 12 years, while tankless heaters may last up to 20 years. As the heater ages, internal components can deteriorate, leading to reduced efficiency and increased chances of failure.

**2. Sediment Buildup:

Water contains minerals and impurities that can settle at the bottom of the tank over time. This sediment buildup not only reduces the heater’s efficiency by insulating the heating element, but it can also lead to corrosion. Corrosion weakens the tank’s structural integrity and increases the risk of leaks.

**3. Corrosion:

Corrosion is the enemy of water heaters, particularly those with steel tanks. The anode rod, a sacrificial component designed to attract corrosion and prevent it from affecting the tank, can become depleted over time. When this happens, the tank itself becomes vulnerable to corrosion, eventually leading to leaks.

**4. High Pressure and Temperature:

Water heaters are designed to handle specific temperature and pressure ranges. If your water pressure is too high or the temperature settings are consistently pushed to their limits, the stress on the heater’s components can accelerate wear and tear.

**5. Neglecting Maintenance:

Regular maintenance is crucial to extend the life of your water heater. Neglecting tasks like flushing the tank to remove sediment, checking and replacing the anode rod, and inspecting for leaks can contribute to premature failure. Routine maintenance can help you catch potential issues early and address them before they lead to major problems.

**6. Inadequate Installation:

Improper installation can set the stage for future failures. Whether it’s incorrect sizing, inadequate insulation, or improper venting, a poorly installed water heater can suffer from decreased efficiency, shorter lifespan, and safety hazards.

**7. Hard Water:

The hardness of your water, determined by its mineral content, can impact the longevity of your water heater. Hard water can accelerate the buildup of scale on heating elements, reducing efficiency and potentially causing the heater to overheat.

**8. Manufacturing Quality:

The quality of the water heater itself plays a role in its durability. Opting for a reputable brand and a higher-quality model can make a difference in how well it stands up to everyday usage.

**9. Thermal Expansion:

When water is heated, it expands. In a closed system, this expansion can lead to increased pressure within the tank. Over time, this pressure can strain the tank’s integrity and even cause leaks if not properly managed.

**10. Environmental Factors:

External factors like the environment in which the water heater is installed can also impact its lifespan. Exposure to extreme temperatures, excessive humidity, and corrosive substances can all contribute to faster deterioration.

In conclusion, water heaters fail due to a combination of factors including age, sediment buildup, corrosion, high pressure and temperature, maintenance neglect, installation issues, water hardness, manufacturing quality, thermal expansion, and environmental influences. While some of these factors are beyond our control, proper maintenance, regular inspections, and filtering your water can significantly extend the life of your water heater. Remember, investing time and effort into caring for your water heater can save you from chilly surprises and unexpected expenses down the line.
