Whether you’re replacing an aging unit or planning a proactive upgrade, understanding your options leads to significant long-term savings. The average American uses large amounts of hot water daily for showers, dishwashing, and laundry.
The key is choosing the right type and size for your home’s specific needs while maximizing available rebates and incentives.
Decoding Water Heater Types: Which is Right for You?
Choosing the right energy efficient water heater is about matching your home’s needs and budget. Let’s break down the main types to find your perfect fit.
First, consider the fuel types available in your home. Most homes in the Birmingham area use electricity and natural gas, though propane and solar are also options. Your available fuel type is a key factor, as converting from one to another can be expensive. We typically recommend working with your existing infrastructure.
Should you focus on upfront cost or long-term savings? We always recommend looking at the bigger picture. A cheaper unit with high running costs isn’t a true bargain.
Conventional Storage Tank Heaters
These are the most common water heaters, functioning like a large insulated thermos to keep a ready reservoir of hot water. Their main advantages are a lower upfront cost and immediate hot water delivery. However, they experience standby heat loss, constantly using energy to keep the stored water hot. Available in gas and electric models, they typically last 8 to 12 years. While electric models are highly efficient at converting energy to heat, gas is often the cheaper fuel in our area.
Pro tip: Insulating the water pipes near your storage tank can easily boost its efficiency.
Tankless (On-Demand) Water Heaters
Tankless models provide endless hot water by heating water directly as you need it, eliminating standby heat loss. These space-saving units mount on a wall and can last 20 years or more, with ENERGY STAR models saving 30% more energy than storage tanks. However, they have a higher upfront cost. Performance can be affected by cold groundwater temperatures, and they have flow rate limitations. Running multiple hot water appliances simultaneously may exceed the unit’s capacity.
Heat Pump (Hybrid) Water Heaters
Heat pump water heaters are the most efficient option, as they move heat rather than creating it. They pull warmth from the surrounding air and transfer it to the water, making them two to three times more efficient than standard electric models. An ENERGY STAR certified unit uses about one-quarter of the energy of a standard electric heater, saving a family of four around $600 annually. They also act as dehumidifiers, a great benefit in Alabama’s climate. However, they require about 700 cubic feet of surrounding air for proper operation, produce some noise, and need a drain for condensate.

Solar Water Heaters
Solar water heaters use the sun’s energy via collector panels on your roof, transferring heat to a storage tank. They can provide up to 60% of a home’s hot water needs but require a backup system for cloudy days. Their performance is highly dependent on climate. While they have the highest initial investment, they offer the lowest operating costs. Solar is a great long-term choice for those looking to minimize their environmental impact.
Your Checklist for Choosing the Perfect Energy Efficient Water Heater
Choosing the right energy efficient water heater is a long-term decision for your comfort and budget. The most important factor is getting the size right. An undersized unit means cold showers, while an oversized one wastes energy.
The First Hour Rating (FHR) is key. It tells you how many gallons of hot water the heater can supply in an hour of peak use. A family of four typically needs an FHR of 60-70 gallons. However, your specific peak demand—based on habits like simultaneous showers and appliance use—is what truly determines the right size.
Understanding Efficiency Ratings: UEF and ENERGY STAR
Efficiency ratings are crucial for predicting savings. The Uniform Energy Factor (UEF) is the primary rating; a higher UEF means better efficiency and lower bills. For the best performance, look for the ENERGY STAR label. These products are third-party tested to meet strict efficiency standards that exceed government minimums, ensuring proven performance and a smaller carbon footprint.
Why Choose an ENERGY STAR Certified Product?
ENERGY STAR certification isn’t just a sticker. It guarantees that a water heater has passed rigorous testing by independent labs to verify its performance and efficiency claims. For example, an ENERGY STAR certified heat pump water heater uses about one-quarter of the energy of a standard model. Choosing ENERGY STAR means investing in reliable technology that delivers proven savings and performance.
Simple Ways to Reduce Hot Water Consumption
You can boost your savings further by reducing hot water consumption. These simple changes work with any energy efficient water heater:
- Low-flow fixtures: Install low-flow showerheads and faucets to use less hot water without sacrificing pressure.
- Wash clothes in cold water: Modern detergents are effective in cold water, saving the energy needed to heat water for laundry.
- Take shorter showers: Cutting just a few minutes from each shower adds up to significant energy savings over a year.
- Insulate pipes: Wrap the hot water pipes near your water heater to prevent heat loss as water travels to your taps.
- Consider drain-water heat recovery: These systems capture heat from used shower water to preheat the cold water entering your heater, recycling energy.
The Champion of Efficiency: A Closer Look at Heat Pump Water Heaters (HPWHs)
Heat pump water heaters (HPWHs) are the champions of efficiency because they move heat instead of creating it, a far more effective method than traditional electric resistance. These units use hybrid technology, combining the high-efficiency heat pump with electric resistance elements for backup during high demand.
Modern HPWHs often include smart controls, such as Rheem’s EcoNet system, for mobile app management, scheduling, and vacation modes, further boosting savings.
Performance, Climate, and Your Home
An HPWH’s performance depends on its environment, with ideal operating temperatures above 38°F. While their efficiency drops in colder weather, the electric backup ensures a reliable hot water supply. For the mild climate in Birmingham, AL, HPWHs are an excellent choice, operating at peak efficiency for most of the year. They do produce some noise (similar to a refrigerator) and have a welcome dehumidifying effect, which is a bonus in humid Southern climates.
Key Installation Considerations for an energy efficient water heater
Proper installation is crucial for HPWH performance. Key requirements include:
- Space Requirements: They need about 700 cubic feet of surrounding air, making them ideal for basements, garages, or large utility closets.
- Airflow Needs: Good air circulation is essential; a louvered door may be needed for closet installations.
- Condensate Drain Line: A drain line is required to remove water produced during dehumidification.
- Location: The space should remain above 38°F for best performance.
- Electrical Requirements: Most units need a 240-volt connection.
Note: Never wrap an HPWH in an insulation blanket, as it blocks airflow.
The Best Savings of a Hybrid Model
The initial investment for a heat pump water heater can be higher than that of a conventional electric or gas water heater. However, the energy savings are so substantial that the payback period is remarkably short, typically around two to three years for a household of four. Over its lifetime, an HPWH can deliver over $4,500 in savings compared to a standard electric water heater. The Rheem ProTerra™ Hybrid Electric Water Heater, for example, uses up to 75% less energy than a standard electric water heater.
Let’s look at a comparison:
| Factor | Standard Electric Water Heater | Heat Pump Water Heater (HPWH) |
|---|---|---|
| Upfront Cost | Lower | Higher |
| Annual Savings | $0 (baseline) | ~$600 (for household of 4) |
| Lifetime Savings | $0 (baseline) | >$4,500 |
| Payback Period | N/A | ~3 years |
These significant savings make HPWHs an incredibly smart long-term investment for homeowners seeking to reduce their energy bills and environmental impact.
