5 Simple Steps to Maintain Your Water Heater & Cut Energy Bills

Your water heater could be quietly wasting energy while working harder than it should. But did you know that with just a few simple maintenance steps, you can keep your system running efficiently, extend its lifespan, and save money month after month? From checking temperature settings to inspecting valves, small actions can make a big difference. If your unit starts showing signs of trouble, we can provide water heater repair in Tempe, AZ, to restore performance and keep your home running smoothly.

Let’s look at the simple steps that keep your water heater running efficiently and help you get the most from your system.

Keep Sediment From Building Up

Sediment naturally settles at the bottom of water heater tanks, which can reduce efficiency and make the unit work harder. Flushing your tank a couple of times a year removes this buildup and helps maintain optimal performance. If an older unit is heavily impacted, schedule a water heater installation for a more efficient system. For homeowners with a newer tankless unit, periodic inspections and tankless water heater repair help prevent mineral buildup from affecting performance. Managing sediment early keeps heating even and energy use lower over time.

Check the Temperature Settings

Many water heaters are often set by factories around 140 degrees, which wastes energy and increases the risk of scalding. Lowering the thermostat to 120 degrees provides plenty of hot water while reducing energy bills. For units that are older or showing signs of wear, a water heater replacement may eventually be recommended to maintain consistent temperatures. For homeowners with a tankless system, proper adjustments and occasional tankless water heater repair keep it operating efficiently and prevent unnecessary wear. Correct temperature settings also reduce strain on internal components, helping your system last longer and perform reliably.

Inspect and Test Valves

The temperature and pressure relief valve is one of the most important safety features on your water heater. Testing it annually confirms it functions correctly and prevents potential overpressure issues. Even a small oversight can impact your water heater, so regular inspection is essential. Checking valves pairs naturally with flushing and temperature management to keep your unit performing reliably.

Check the Anode Rod

The anode rod inside a traditional tank-style water heater protects the tank from rust by attracting corrosive elements in the water. As the rod wears down, the tank itself becomes more vulnerable to corrosion. If the anode rod is ignored for too long, a water heater replacement may be needed sooner than expected. Checking the anode rod and replacing every 1-3 years, or when heavily corroded can extend the life of the tank and help maintain efficient operation.

Monitor for Leaks and Corrosion

Leaks or corrosion are early warning signs that a water heater might need attention. Small drips or rust around connections can indicate that water heater repair will soon be required. Catching these signs early prevents inconvenience and keeps your system functioning properly. Visual inspections around the tank, pipes, and fittings allow homeowners to act before minor issues interfere with daily routines.

Tankless heaters can also leak from the connectors, which can lead to corrosion. When leaks or corrosion become extensive, we recommend prompt tankless water heater replacement.

FAQ: Water Heater Maintenance Questions

How often should I flush my water heater tank?

Every six to twelve months, depending on local water quality.

Can I adjust the thermostat myself?

Yes, most units have an accessible dial, but always check the manufacturer’s instructions.

Do tankless water heaters need maintenance?

Yes. Tankless water heaters require regular maintenance, primarily flushing the heat exchanger to remove scale buildup. Flushing is typically needed annually or every one to two years, depending on water hardness. When scale buildup or performance issues are found during service, tankless water heater repair helps restore proper heating efficiency and protect internal components. Professional services are recommended to avoid warranty issues.

How do I know if my water heater needs repair or replacement?

Look for leaks, inconsistent water temperatures, strange noises, or corrosion.

How often should the anode rod be replaced?

Generally every one to two years, or when it shows heavy corrosion.
