Most Popular Water Heater Brands of 2025: A Comprehensive Review

The Cost of Choosing a Suboptimal Water Heater

Going with a lower-quality brand might seem like a way to save money upfront, but it often leads to more expenses in the long run. Cheaply made water heaters can suffer from the following:

• Frequent breakdowns — Poor manufacturing can lead to leaks, heating element failures and corrosion, requiring costly repairs or early replacement.
  
• Higher energy bills — Inefficient models waste energy, forcing your heater to work harder and raising your energy bills.
  
• Short warranties and poor support — If your unit breaks down and the warranty is lacking (or customer service is difficult to reach), you could be left footing the bill for unexpected repairs.

A high-quality water heater from a reputable brand is built to last — and when it does need servicing, you’ll have the customer support you need.

Why Energy Efficiency Matters

Water heating accounts for about 18% of your home’s energy usage, according to the U.S. Department of Energy. Choosing an ENERGY STAR-certified water heater or one with high-efficiency features can make a big difference. Over time, a more efficient model can lead to hundreds of dollars in savings on your energy bills while also reducing your home’s carbon footprint.

The best water heaters have features like:

• Heat pump technology — Uses less electricity by pulling heat from the air.
• Tankless water heating — Provides hot water on demand, reducing standby energy loss.
• Smart temperature controls — Allow you to optimize energy use through scheduling and remote adjustments.

Warranty and Customer Support: Your Safety Net

A good warranty is a sign of a well-made product. The best brands offer warranties ranging from 6 to 12 years, covering critical components like the tank and heating elements. Strong customer support can also make a big difference if you ever need troubleshooting, repairs or replacement parts.

Before choosing a brand, check the following:

• Warranty length and coverage — Does it cover leaks, heating elements and manufacturer defects?
• Customer Service reputation — Is the company easy to contact for support?
• Availability of replacement parts — Can you find parts easily, or will repairs take weeks?

Smart Features

Modern water heaters do more than just heat water — they make your life easier. Some of the latest models include:

• WiFi connectivity — Letting you monitor energy use and adjust settings remotely.
• Leak detection technology — Alerting you to leaks before they cause costly damage.
• Self-cleaning systems — Reducing sediment buildup and extending the unit’s lifespan.

These features not only improve convenience but can also prevent unexpected breakdowns and extend the life of your water heater.

Learning from Other Homeowners

When in doubt, see what other buyers are saying. User reviews and ratings provide real-world insight into:

• How well the water heater performs over time.
• Any recurring issues, such as leaks or sensor malfunctions.
• The quality of customer service and warranty support.

A high-rated brand with strong customer satisfaction is more likely to deliver a product that meets your expectations.

A Smarter Choice Pays Off

Investing in a reliable, energy-efficient water heater from a trusted brand pays itself off with lower energy costs, fewer repairs and a longer lifespan. In the next section, we’ll show you how to find the best brand for your home — from choosing the right type to considering budget and installation factors.

1. Type of Heater: Different water heaters serve different purposes:

• Tankless water heaters provide hot water on demand, saving space and energy. However, they usually cost more upfront.
  
• Storage tank water heaters have a reservoir of water that’s heated and ready for you to use. However, they require more energy to maintain the temperature of the water.
  
• Heat pump water heaters don’t need as much energy to heat your water, since they pull heat from the air.
  
• Solar water heaters rely on sunlight instead of electricity or gas, making them ideal for sunny climates.
  

2. Capacity: A household of one or two might get by with a 30- to 40-gallon tank, but a family of five or more may need at least 50 gallons. If you have frequent guests or a large home with multiple bathrooms, a high-capacity tank or tankless system might be your best bet for avoiding cold showers.

3. Fuel Source: Water heaters run on electricity, natural gas, propane, or solar power. If you’re replacing an old unit, it’s easiest to stick with the same fuel type unless you’re planning an upgrade.

4. Energy Costs: As mentioned earlier, water heating accounts for a significant portion of household energy use, so it pays to choose an efficient model. Here’s what to consider as you research energy-efficient water heaters:

• Energy Factor (EF): The EF rating tells you how efficiently a water heater converts energy into hot water. Higher ratings mean better efficiency. Look for ENERGY STAR-certified models for maximum savings.
  
• Environmental Impact: Some brands focus on sustainability with eco-friendly materials, higher efficiency ratings, and lower carbon emissions. Heat pumps and solar water heaters have the lowest environmental impact.
  

5. Budget Considerations: Cost isn’t just about the purchase price — it’s about long-term value. When comparing prices, here are some factors to consider:

• Upfront Costs vs. Long-Term Savings: Energy-efficient models and longer warranties often come at a higher initial price, but they can save you hundreds of dollars on energy bills and repairs over time.
  
• Rebates and Incentives: Check for local utility rebates, tax credits or federal incentives for purchasing energy-efficient appliances. These can make higher-end options more affordable.
  

6. Brand Reputation and Reliability: A well-known brand with a solid track record is usually a safer bet than a lesser-known one with limited customer feedback.

• Warranty: A good warranty can be a sign of product quality. Many leading brands offer 6 to 12 years of coverage on tanks and heating elements.
  
• Customer Reviews: Real-world experiences tell you how a water heater actually performs over time. Look for patterns in reviews — repeated issues like leaks or unreliable heating could be a red flag.
  
• History and Legacy: Established brands that have been in the industry for decades often have more reliable products and better service networks.
  

7. Ease of Installation and Maintenance: Some water heaters require complex installation, while others are plug-and-play.

• Installation Requirements: A tankless or heat pump water heater may require electrical upgrades, gas line modifications or venting changes, which can increase installation costs.
  
• Maintenance Needs: Some models are easier to maintain than others. Look for brands that offer readily available replacement parts and straightforward cleaning processes to extend the unit’s lifespan.
  

8. Convenience and Safety Features: Modern water heaters come with extra features that enhance performance and safety.

• Smart Features: Some units have WiFi connectivity that lets you adjust temperature, track energy usage, or receive maintenance alerts from your phone.
  
• Safety Features: Look for models with auto shut-off, leak detection sensors and pressure relief valves to prevent water damage and overheating.
  

9. Customer Support: Great customer support can make a huge difference if you ever run into problems with your water heater.

• Post-Sale Service: A brand with responsive, helpful customer support can save you time and frustration if you need repairs or warranty service.
  
• Availability of Parts: Some brands make it easy to find replacement parts, while others require special orders that can take weeks. Make sure you can get the parts you need quickly.

Tip: Questions to Ask When Buying a Water Heater

Once you narrow down your list of options and begin shopping, here are some questions you may want to consider asking a sales representative or plumbing professional before making your selection:
