5 Proven AO Smith Water Heater Tips for Reliable Use

AO Smith Water Heater

An AO Smith water heater is trusted by homeowners and businesses across Houston for its durability, efficiency, and long service life. However, even the most reliable water heater needs regular care to keep delivering consistent performance. Without proper maintenance, sediment buildup, corrosion, and mechanical wear can shorten your unit’s life and lead to costly repairs.

In this guide, we’ll share five proven tips to extend the life of your AO Smith water heater, reduce energy bills, and avoid unexpected breakdowns. We’ll also connect you to trusted Houston-based professionals like Value Water Heaters who specialize in commercial and residential water heater services.


1. AO Smith Water Heater Tip #1 – Flush the Tank Yearly

Over time, sediment and mineral buildup can settle at the bottom of your AO Smith water heater tank, reducing heating efficiency and potentially damaging internal components.
How to do it:

  • Turn off the power (for electric models) or gas supply (for gas models).
  • Connect a garden hose to the drain valve at the bottom of the tank.
  • Drain the water until it runs clear.

Benefits:

  • Prevents corrosion
  • Improves heating efficiency
  • Extends the unit’s life

2. AO Smith Water Heater Tip #2 – Inspect and Replace the Anode Rod

The anode rod is your tank’s first line of defense against corrosion. It attracts rust-causing minerals, keeping the tank itself protected.
When to check: Every 1–3 years, depending on your water quality.
Replacement rule: If it’s corroded to less than ½ inch or coated with calcium, replace it immediately.

This simple step can add years to your water heater’s lifespan and prevent expensive tank replacements. For expert inspections in Houston, check Value Water Heaters on Bing Maps.


3. AO Smith Water Heater Tip #3 – Adjust the Temperature for Safety and Savings

Your AO Smith water heater is typically set at 140°F by default, but lowering it to 120°F offers major benefits.
Advantages:

  • Prevents scalding accidents
  • Reduces energy consumption
  • Slows mineral buildup

This small change can cut your water heating costs by up to 10% annually while extending the life of your heating elements.


4. AO Smith Water Heater Tip #4 – Insulate the Tank and Hot Water Pipes

Heat loss from the tank and exposed pipes forces your unit to work harder, increasing wear and energy usage.
How to insulate:

  • Wrap your water heater in an insulating blanket (avoid covering the top on gas models).
  • Use foam pipe insulation for the first 3–6 feet of hot water piping.

Result: Faster hot water delivery, lower energy bills, and less strain on your system.


5. AO Smith Water Heater Tip #5 – Schedule Annual Professional Maintenance

While homeowners can handle basic care, a licensed technician can perform a full inspection of your AO Smith water heater. This includes checking the pressure relief valve, burner, thermostat, and seals.
