Rheem vs. A.O. Smith Water Heaters: Which Is Better for Your Home in the Ohio Valley?

Quick Answer

Rheem is the better choice for most Ohio Valley homes because it lasts longer, requires less maintenance, and delivers higher efficiency—especially in standard tank and hybrid heat pump systems. A.O. Smith can work in certain situations, but its retail-grade components and higher upkeep make Rheem the more reliable long-term investment.

Rheem vs. A.O. Smith Water Heaters: Transparent Comparison From a Rheem Pro Partner

If your water heater is leaking, running out of hot water, or reaching the 10-year mark, comparing brands can feel overwhelming. Homeowners in Steubenville, Weirton, Wintersville, Toronto, and nearby towns ask us the same question every week.

Full transparency: Honest Fix is a Rheem Pro Partner, and we exclusively install Rheem for replacements.

We continue to service A.O. Smith water heaters, but we no longer install them because Rheem consistently performs better in reliability, lifespan, warranty support, and long-term maintenance in our region’s water conditions.

Below is the same clear, honest comparison we give homeowners at their kitchen table.

1. Reliability and Lifespan

Winner: Rheem

Based on installations and repairs across the Upper Ohio Valley:

• Rheem typically lasts 12–15 years
• A.O. Smith typically lasts 10–12 years

Why Rheem lasts longer here:

• EverKleen self-cleaning system reduces sediment (a major issue in Wellsburg, Brilliant, and Mingo Junction)
• Fewer gas valve and thermostat failures
• Better corrosion resistance in hard-water conditions

A.O. Smith retail units (Signature Series) often include:

• Plastic drain valves
• Lighter-duty components
• Lower corrosion resistance
• More frequent anode rod replacement

If you want a tank that needs fewer repairs over its lifetime, Rheem is the proven choice.

2. Hybrid Heat Pump Water Heaters

Winner: Rheem ProTerra

Hybrid heat pumps deliver the biggest energy savings of any water heater available today.

Rheem ProTerra Advantages:

• Up to 4.07 UEF (industry-leading efficiency)
• Smart EcoNet monitoring and alerts
• Very quiet operation
• Reliable performance in Ohio Valley basements

A.O. Smith’s Voltex models are acceptable, but field data shows:

• Lower maximum efficiency
• More maintenance
• Less predictable performance in cooler basement environments

For long-term efficiency and comfort, Rheem is the better choice.

3. Tankless Water Heaters

Winner: Rheem

A.O. Smith has produced good tankless models in the past, but Honest Fix no longer installs A.O. Smith products due to quality inconsistencies and warranty limitations.

Rheem tankless advantages:

• High-efficiency condensing models
• Stronger warranty support
• Smart controls and diagnostics
• More consistent performance when paired with water treatment

If you want a tankless water heater installed correctly and supported for the long haul, Rheem is the brand we stand behind.

4. Efficiency Comparison

Standard Gas Tanks

• Rheem: Up to 0.72 UEF
• A.O. Smith: Up to 0.70 UEF

Hybrid Heat Pumps

• Rheem: Up to 4.07 UEF
• A.O. Smith: Up to 3.6 UEF

Tankless

Both brands offer strong UEF numbers, but Rheem provides more reliable long-term performance and support.

5. Maintenance Needs

Winner: Rheem

Rheem units require less routine upkeep in real-world homes.

Rheem Advantages:

• EverKleen reduces sediment buildup
• Anode rods last longer
• Fewer nuisance repairs
• Performs better for homeowners who forget annual flushing

A.O. Smith Challenges:

• Retail models require more frequent maintenance
• Anode rods degrade more quickly
• Sediment builds faster without brass drain valves
• More common thermostat and element failures in electric models

If you want a low-maintenance system, Rheem is the more practical fit.

6. Warranty and Risk

Winner: Rheem

This is a major reason Honest Fix installs Rheem exclusively.

Rheem Warranty Strengths:

• Up to 12 years tank and parts
• Optional labor coverage available
• Faster, clearer claims process
• Coverage that aligns with Honest Fix’s guarantees

A.O. Smith Warranty Limitations:

After the first year, homeowners are responsible for:

• All labor
• All shipping
• All handling
• All installation costs

This creates unexpected long-term expenses many homeowners are unaware of.
