Reliable hot water matters more than you realize. It’s part of your everyday life—showers, handwashing, dishwashing, and cleaning. As winter approaches, having reliable hot water becomes even more important for your comfort and health. When your water heater struggles to keep up, it shows in your everyday use: showers that feel weak, suddenly turn cold, or take a long time to heat back up are clear warning signs that your system may need attention. Left unchecked, wear, mineral buildup, or other issues can lead to costly repairs—or even complete failure.

That’s why regular maintenance is so important. A routine water heater tune-up clears hard water deposits, checks for corrosion, and makes sure your system runs dependably—so you always have hot water when you need it. Here’s what every Utah homeowner should know about maintaining a healthy water heater:

Hard Water Challenges in Northern Utah

Across the Wasatch Front, homeowners often deal with hard water—water that contains high levels of “hard” minerals like calcium and magnesium. It starts high in the mountains, where rain and snowmelt seep through layers of limestone and sandstone, absorbing minerals along the way. By the time that water reaches Utah’s treatment plants and flows from your tap, it’s already rich in these minerals.

Utah’s mineral-rich water isn’t harmful to your health, but it does leave behind stubborn mineral deposits inside your water heater. These deposits can cause scaling in tanks or heating elements, which makes your water heater work harder and shortens its lifespan.

Routine maintenance removes these deposits and helps protect your system from further wear. The exact maintenance needs—and how often you should schedule service—depend on whether you have a tanked or tankless water heater.

Tanked vs. Tankless Water Heaters: Unique Challenges

Both tanked and tankless water heaters deal with the unique challenges of Utah’s hard water. Some water also has naturally corrosive properties, which can wear down metal components over time. Over time, this can cause the metal parts to pit, rust, or corrode.

If left unchecked, both scale and corrosion can decrease efficiency and shorten your water heater’s life.

Tanked Water Heater: What Happens Inside Your Tank

Tanked water heaters store heated water in a single tank. Over time, mineral deposits settle as a layer of sediment at the bottom of the tank. This buildup reduces heating efficiency and adds extra wear on internal components.

For tanked systems, a water heater flush clears out sediment and mineral deposits from the bottom of the tank, restoring efficiency and preventing premature wear.

Corrosion in tanked units often appears as rust along the tank walls or at fittings. A sacrificial part called the anode rod attracts corrosion to itself, protecting the tank. Over time, the rod wears down and should be inspected and replaced every 3–5 years, depending on water quality and usage

Tankless Water Heater: What Happens Inside Your Heat Exchanger

Tankless systems heat water “on demand”—which eliminates the need to store gallons and gallons of water. However, tankless units are still affected by mineral buildup. Hard minerals cling to heating elements and inside the heat exchanger, forming scale.

A process known as descaling removes this buildup and helps maintain proper flow and consistent water temperature

Corrosion in tankless units often occurs inside the heat exchanger or at connections where moisture and minerals accumulate. Unaddressed corrosion can lead to leaks or hidden damage that may not be noticed until performance drops.

For both tanked and tankless units, regular maintenance—including flushing/descaling and professional inspections—keeps your system running efficiently and extends its lifespan.

What a Water Heater Tune-Up Includes

A water heater tune-up is more than just flushing or descaling—it combines cleaning, fine-tuning, and professional inspection.

Flushing a tanked water heater or descaling a tankless unit is an important first step. These cleaning procedures remove mineral deposits from Utah’s hard water, restoring efficiency and addressing visible issues like sediment buildup or reduced hot water flow.

But clearing mineral buildup doesn’t solve hidden problems like worn or corroded parts. Professional inspection and fine-tuning the system is needed to catch damage and leaks before they can become costly repairs—or worse, safety hazards.

A professional tune-up generally includes:

Flushing tanks or descaling heating elements: Homeowners can perform basic flushing on a tanked system, but descaling tankless units or stubborn scale should be done by a professional. Heat exchangers are delicate, and improper cleaning can cause damage or reduce efficiency.

Testing and adjusting thermostats: Licensed plumbers ensure safe, efficient temperature settings, preventing scalding or wasted energy.

Inspecting pressure relief valves: Professionals check these critical safety devices to prevent dangerous pressure buildup.

Checking for leaks, corrosion, or worn components: Plumbers detect early rust, anode rod wear, and hidden corrosion, avoiding expensive emergency repairs.

Making efficiency and temperature adjustments: Professionals optimize performance while accounting for Utah’s hard water and other local conditions.

These steps keep your water heater safe, reliable, and ready to meet your household’s hot water needs.

5 Advantages of Staying on Top of Water Heater Maintenance

Regular inspections and tune-ups protect your water heater and household. Here are the main benefits you can expect from staying on top of maintenance:

Lower Utility Bills: Well-maintained water heaters are more efficient, and efficient water heaters use less energy—so you’ll save on your energy bills!

Extended Appliance Lifespan: Routine maintenance prevents small issues from becoming major problems, which helps your water heater reach its full functional lifespan.

Reliable Hot Water Anytime: No more lukewarm showers after ski mornings in Park City or Provo Canyon hikes. A tuned-up system helps ensure steady hot water

Fewer Emergency Repairs: Early detection of corrosion, leaks, or worn parts can save thousands of dollars in costly emergency fixes.

Peace of Mind: Knowing your water heater is professionally maintained means one less thing to worry about while you focus on family, work, and Utah adventures.

By keeping up with regular tune-ups, you can enjoy all these advantages and avoid unexpected problems down the line.

When to Schedule Your Water Heater Tune-Up

Reliable hot water matters more than you realize. It’s part of your everyday life—showers, handwashing, dishwashing, and cleaning. As winter approaches, having reliable hot water becomes even more important for your comfort and health. To keep your system running efficiently and prevent costly issues, follow these general guidelines recommended by experts and water heater manufacturers:

Tanked Water Heaters: Schedule maintenance annually, or every 6-9 months if hard water is severe.

Tankless Water Heaters: Schedule maintenance every 1-2 years, with annual service recommended for homes with high mineral content.

Signs of Wear or Corrosion: Any signs of rusty water, unusual sounds, or inconsistent hot water should trigger an immediate inspection, regardless of your regular maintenance schedule.

Following these expert-recommended schedules keeps your water heater efficient and extends its lifespan, while addressing any warning signs immediately helps prevent unexpected breakdowns.
