Not many people think about their water heater until something goes wrong. A leak, frequently running out of hot water, or a system that fails altogether might be the first time you’ve looked at your water heater in years. Just like that, you’ve got to choose between tank, tankless, and heat pump systems while evaluating costs, efficiency, and warranties.
At Mattioni, we help homeowners through their water heater replacement process every day. We know what makes each different type of system stand out, so we can help you figure out which one is best for your home.
In this article, we’ll compare five of the industry leaders, so you can learn about and decide what might be a good fit (and what might not be a good fit) for your home.
1. Bradford White Standard Tank Water Heaters (Best Overall Standard Tank Water Heater)
Best for: Homeowners who want a dependable, installer-grade tank-type water heater for a simple, high-quality replacement.
First-Hour Rating: 81 gallons (50-gal model), 135 gallons (75-gal model) – What is First Hour Rating?
Recovery: 43 GPH (50-gal model), 82 GPH (75-gal model) – at a 90°F rise
Efficiency: 0.63 UEF (What is UEF?)
Typical Member Cost: 50 gallons: $3,100-$4,100, 75 gallons: $4,100-$5,200 (price ranges depending on natural gas or propane as fuel source)
Member Warranties: 6-year tank and parts
Bradford White is the brand many plumbers choose for their own homes. It’s a proven design that’s easy to service, with good parts support and no “retail-grade” corners cut. Available in both natural gas and LP (propane) models, they’re flexible to your home’s fuel source. It’s the leading choice for anyone looking for a simple like-for-like tank replacement where balanced reliability and installation costs matter more than the efficiency gains of the next water heaters on our list.
2. Navien NPE-A2 Series Tankless Water Heater (Best Tankless for Faster Hot Water)
Best for: Larger homes with long pipe runs, or anyone tired of waiting for or running out of hot water.
First-Hour Rating: N/A (continuous)
Recovery: 4.2 GPM – at a 90°F rise
Efficiency: Up to 0.97 UEF
Typical Member Cost: $5,400 (to replace an existing tankless water heater), $6,200 (to install a new Navien tankless water heater)
Member Warranties: 15-Year heat exchanger, 5-year Parts, 5-year Labor
Navien’s tankless water heaters stand out because they have a built-in recirculation pump, so hot water arrives at each of your taps faster, and you won’t run out of hot water during peak usage times.
With up to 0.97 UEF efficiency, it’s also one of the most efficient gas water heaters available. They’re ideal for larger homes where the bathrooms are far from the water heater. They may not be a good fit for homes with undersized gas lines or small homes with short pipe runs that won’t fully benefit from built-in recirculation.
3. Rheem Marathon Plastic Tank Water Heater (Best Long-Lasting Electric Tank)
Best for: Homes with an existing electric water heater, homes with hard water, or owners who want “the last water heater you’ll buy.”
First-Hour Rating: 51 gallons (50-gal model), 83 gallons (85-gal model)
Recovery: 21 GPH – at a 90°F rise
Efficiency: 0.90-0.92 UEF
Typical Member Cost: $4,200-$4,400 (50 gallons)
Member Warranties: Lifetime Tank, 6-year parts, 6-year labor
The Marathon’s plastic tank is what sets it apart from any other water heater. It can’t rust or corrode like a steel tank does, has no anode rod to replace, and comes with a lifetime tank warranty for the original owner. Heavy foam insulation keeps water hot for hours, which cuts standby losses.
It works especially well for homes with hard water that would corrode and wear out a steel tank. The lifetime tank warranty is why it’s often called ‘the last water heater you’ll ever buy.’ It might not be a good fit for homes currently utilizing natural gas or LP (propane), homeowners planning to move within a few years, or anyone looking for just the lowest replacement price.
4. Rheem ProTerra Hybrid Heat Pump Water Heater (Best Water Heater for Energy Savings)
Best for: Homes with an existing electric water heater looking to cut water heating bills by up to 70%.
First-Hour Rating: 67 gallons (50-gal model), 87 gallons (80-gal model)
Recovery: 27 GPH – at a 90°F rise
Efficiency: 3.88 UEF (50 gallons), 4.07 UEF (80 gallons)
Typical Member Cost: $5,500 (50 gallons), $8,000 (80 gallons) plus any added installation requirements like electrical work, condensate drainage, and space restrictions.
Member Warranties: 10-year tank and parts, 6-year labor
Instead of heating water with electric resistance elements or fuel-consuming combustion, the ProTerra pulls heat from the surrounding air. Its UEF of 3.88-4.07 (depending on the tank size) is up to about 4x more efficient than a standard electric water heater.
Smart features like the EcoNet app, LeakGuard automatic shutoff, and multiple operating modes add convenience and protection. It also dehumidifies the space it’s in, which is an added bonus in basements. Available utility rebates can greatly lower the upfront cost.
It may not be a good fit for small closets or tight spaces that don’t provide enough air circulation around the unit, or installs next to living spaces where cool air would bother you.
5. Bradford White Indirect Water Heaters (Best Water Heaters for Homes with a Boiler)
Best for: Homes with a gas or oil boiler that want high-volume hot water without a separate burner.
First-Hour Rating: About 165 gallons (50-gal model paired with a typical 100,000 BTU boiler)
Recovery: About 135 gallons per hour (at a 90°F rise, with a typical 100,000 BTU boiler)
Efficiency: Up to 95% AFUE with a high-efficiency condensing boiler (matches your boiler’s efficiency)
Typical Member Cost: Varies based on installation requirements of the indirect water heater and boiler hook-up.
Member Warranties: Limited lifetime tank and heat exchanger, 6-year parts
An indirect water heater is a highly insulated storage tank that depends on your boiler to heat water through coils, rather than using its own burner. Since your boiler does the heavy lifting, an indirect tank can deliver far more hot water than a standard tank. With no burner of its own, it also tends to outlast conventional tanks, which is backed with a limited lifetime warranty on the tank and heat exchanger from Bradford White.
However, since your boiler is the heat source, an indirect water heater’s performance depends on your boiler’s size and condition. It also means your boiler will need to run in the summer. Indirect water heaters may not be a good fit for homes with forced-air furnaces or heat pumps (without a boiler), or homeowners who want hot water that doesn’t depend on the boiler running.

Quick answers: Best water heaters for 2026 & 2027
What is the best water heater for 2026?
The best water heater depends on your home's fuel source and priorities. For a simple, reliable gas or propane tank replacement, Mattioni recommends Bradford White standard tanks. For faster, continuous hot water, the Navien NPE-A2 tankless is the top pick. For electric homes, the Rheem ProTerra hybrid heat pump offers the biggest energy savings, while the Rheem Marathon offers a lifetime tank warranty. Homes with a boiler get the most hot water from a Bradford White indirect water heater.
What is the best tankless water heater?
The Navien NPE-A2 series is our top tankless pick. Its built-in recirculation pump gets hot water to your taps faster, it's one of the most efficient gas water heaters available, and it delivers about 4.2 gallons per minute at a 90°F temperature rise. Typical Mattioni member cost is $5,400 to replace an existing tankless unit or $6,200 for a new tankless installation.
What is the most energy-efficient water heater?
The Rheem ProTerra hybrid heat pump water heater is the most efficient option we install, with a UEF of 3.88 (50 gallons) to 4.07 (80 gallons). That's up to about 4 times more efficient than a standard electric water heater, which can cut water heating bills by up to 70%. Typical Mattioni member cost is $5,500 for 50 gallons and $8,000 for 80 gallons, plus any added installation requirements.
What is the longest-lasting electric water heater?
The Rheem Marathon is built to last. Its plastic tank can't rust or corrode, has no anode rod to replace, and comes with a lifetime tank warranty for the original owner. It's a strong choice for homes with hard water. Typical Mattioni member cost is $4,200 to $4,400 for a 50-gallon model.
What is the best water heater for a home with a boiler?
An indirect water heater, such as the Bradford White PowerStor, uses your boiler to heat water through a coil inside an insulated storage tank. Paired with a typical 100,000 BTU boiler, a 50-gallon model delivers about 165 gallons of hot water in the first hour. It includes a limited lifetime warranty on the tank and heat exchanger, but its performance depends on your boiler's size and condition.
