How Long Will Your Water Heater Last? A Homeowner’s Guide

If you’re like most homeowners in and around Flat Rock, MI, you don’t give much thought to your water heater. Tucked away in your basement or a utility closet, your water heater operates silently, providing you with all the hot water you and your family need—until the day it doesn’t, and you’re stuck with a cold shower.

That brings up an important question: How long can you expect your water heater to last, and are there steps you can take to extend its life? Superior Comfort Heating and Cooling, a trusted name in water heater service throughout the Flat Rock area since 2007, is here to guide you through the essentials and offer expert solutions that can keep your system running smoothly. In this post, we’ll cover tank versus tankless life spans and recommended maintenance. We’ll also discuss the importance of timely repairs.

Tank vs. Tankless Water Heaters

Tank Water Heaters

Traditional tank water heaters are the most common type found in homes across Flat Rock and the surrounding area. These systems use a large, insulated tank—typically 30 to 80 gallons in capacity—to store and supply hot water. Cold water enters the tank at the bottom, where it is heated by either gas or electricity. Once heated, the water remains in the tank until needed. When hot water is called for, it exits the tank, which then refills with cold water, repeating the process.

Many homeowners prefer traditional tank water heaters because they are familiar, affordable and effective. Their advantages include a lower up-front cost and consistent performance. They are also straightforward to install and operate. However, there are some drawbacks, such as higher ongoing energy use and a limited supply of hot water. With proper care, a traditional model typically lasts between eight and 12 years.

Tankless Water Heaters

Rather than relying on a large storage tank, tankless water heaters provide hot water on demand. When hot water is called for, cold water flows across a gas or an electric burner where it is rapidly heated and then delivered directly to a faucet or an appliance. This process continues as long as hot water is needed, shutting off automatically when demand stops. Unlike tank systems, there is no storage of hot water.

The advantages of tankless models include improved energy efficiency, a space-saving design, and an endless supply of hot water. However, there are some disadvantages, such as higher up-front costs, a limited flow rate, and a slight delay in hot water delivery. Installation may also be more complex and time-consuming, particularly in older homes. With proper maintenance, tankless systems typically have a life span of about 15 to 20 years.

Making the Right Choice

So, which is better—a traditional tank water heater or a tankless one? As you might have guessed, that depends on several factors, including your household size, hot water usage, budget, and energy efficiency goals. Superior Comfort Heating and Cooling has the expertise to install, maintain, and repair both tank and tankless models and would be happy to assess your needs and help you choose the best option for your home.

The Importance of Routine Maintenance

Regardless of whether you choose a tank or tankless model, Superior Comfort Heating and Cooling provides the water heater maintenance needed to keep your unit operating at peak efficiency, prevent unexpected breakdowns, and extend its life span. Without regular upkeep, your system may suffer a shortened life due to rust and corrosion, anode rod depletion, and sediment buildup. Here’s a closer look at how each of these issues can impact your system.

Rust and Corrosion

Traditional tank systems store water inside a metal reservoir for long periods. Add in the oxygen and minerals naturally present in water, and you have the ideal conditions for rust and corrosion. While tankless units don’t store water and are generally less prone to rust, they can still experience corrosion, especially in the heat exchanger where mineral deposits accumulate.

Gas-powered models are also susceptible to corrosion around components if gas line leaks occur. When left unchecked, rust and corrosion can significantly reduce the life of your water heater and eventually cause it to fail. At that point, you will need to install a new water heater.

Anode Rod Depletion

To protect the interior of the tank, traditional water heaters use sacrificial anode rods. These rods corrode gradually over time, drawing corrosive elements away from the tank walls. However, once the rod is fully depleted, the tank becomes vulnerable to internal corrosion. If not replaced in time, this can lead to leaks, reduced efficiency and premature system failure.

Sediment Buildup

Hard water contains minerals like calcium and magnesium that can settle at the bottom of the reservoir. Over time, this sediment traps heat, causing the tank to overheat and corrode more quickly. This not only reduces efficiency but also can lead to strange noises, higher energy bills, and, ultimately, a shorter water heater life span.

Extend Your Water Heater’s Life With Our Routine Maintenance

To keep your unit operating safely and efficiently, Superior Comfort Heating and Cooling performs a full range of maintenance tasks designed to spot potential issues early, extend system life, and maximize performance. During a routine maintenance visit, we will:

• Visually inspect your water heater and all associated piping, checking for signs of corrosion or cracks
• Check for water pooling or floor stains that could indicate a leak
• Inspect the anode rod and replace it if needed
• Test the temperature and pressure relief valve to ensure proper operation
• Check the thermostat, verify its setting, and adjust it to the recommended temperature
• Inspect the heating element in electric models and the burner and ignition system in gas models
• Flush the tank in models where this function is applicable
• Ensure gas connections are secure and leak-free, and confirm proper ventilation
• Check the inlet and outlet water pressures
• Inspect all electrical components, including wiring, circuit boards, sensors, and connections

Fast Repairs When Things Go Wrong

Regardless of how new or well-maintained your water heater is, there is always the chance that something could go wrong. You might notice water pooling around the base of your water heater, which is often an early sign of a leak. Or perhaps you begin to hear unusual noises coming from within the unit. In some cases, you may experience inconsistent water temperatures or even a complete lack of hot water.

When problems arise, time is of the essence. A small leak can quickly escalate into significant water damage, affecting your flooring and the water heater itself. Strange noises might indicate internal damage, sediment buildup, or pressure issues that, if ignored, could lead to system failure. And of course, if you’re without hot water altogether, you’ll want that resolved immediately.
