What is the Life Expectancy of a Commercial Water Heater?

Commercial water heaters serve an important function. They supply enough hot water during peak operating hours without overtaxing the system. Being aware of your commercial water heater's lifespan allows you to take action before costly breakdowns arise.

They typically last 10 years before needing replacing. If yours has reached that milestone, now might be an opportune time to consider replacement options.

General guidelines suggest that commercial water heaters that have been regularly flushed and have had their anode rod replaced could last 12 years with proper care, though longevity will depend on various factors.

Factors that affect the life expectancy of a commercial water heater

Here are some key factors that can lessen your unit’s lifespan.

Water hardness

Water hardness measures the concentration of calcium and magnesium dissolved in water, and different testing methods report its concentration. Over time, hard water flowing through pipes can result in the build-up of mineral deposits, which can reduce unit efficiency.

Water hardness is an integral factor in the lifespan of commercial water heaters, since mineral deposits can reduce its lifespan significantly.

Amount of unit use

The more often a commercial water heater is used, the shorter its lifespan. This is because the constant heating and cooling of the water tank increases wear and tear on the tank's components. Regular maintenance and flushing can help to extend its life expectancy, however, by reducing sediment build-up in the tank.

Quality of installation

The quality of installation is also an important factor in the lifespan of a commercial water heater. Poorly installed water heaters can cause leaks that lead to corrosion, which can significantly reduce efficiency and increase the chance of breakdowns or malfunctions.

Additionally, it's important to have a properly sized unit for your needs; otherwise, it will be overworked and won't last as long. Choosing an appropriate unit for your specific needs can help to extend its life expectancy and ensure optimal performance.

Quality and type of insulation used on tank walls

The quality and type of insulation used on a water heater tank can also affect the lifespan of your unit. Insulation helps keep heat within the tank, which increases efficiency and reduces energy costs.

Higher-quality insulation materials are stronger and more effective at retaining heat, reducing the amount of energy lost and helping to extend the life expectancy of your commercial water heater. 

The importance of maintenance

Commercial water heaters are constantly running. Unsurprisingly, they’ll need maintenance to ensure they run for as long as possible.

Those who act quickly when a unit needs servicing can prevent severe breakdowns that affect comfort. Signs that it may soon reach its end include discolored water, leakage issues, or strange noises.

With proper maintenance, commercial water heaters can last much longer. To maximize its lifespan, ensure the unit is serviced every year.
