If you're looking for a reliable water heater, I've had great experience with the 40-gallon tall version I bought 8 months ago. It was professionally installed and has been working well ever since, providing plenty of hot water for my family. Give it a try if you're tired of water heaters that don't hold up!

Bradford BWC 50GAL Water Heater

Best Corrosion-Resistant Water Heater

If you want something durable and corrosion- and rust-resistant, the Bradford water heater is one to consider. It has a Vitraglas lining that protects the tank from some destructive elements of hot water, making it last longer and function better.

Backed by a 6-year warranty, you know you’re getting your money’s worth when choosing this option. It is built to last for years to come, making it an excellent option for your 3-4 person household.

What We Like

Non-Simultaneous and Simultaneous Options Available

With this water heater, you can choose both simultaneous and non-simultaneous operations. This allows you to heat both elements at the same time, or just one at a time.

Fully Automatic Controls

This boasts a surface-mount thermostat that allows automatic temperature control. This makes it easier for you. The sensitive manual also has an energy cutoff to prevent overheating, making this safer for both your household and the tank.

Hydrojet Total Performance System

This technology is advanced compared to other heaters. The hydrojet system allows for a cold water inlet, reducing sediment build-up inside the tank. It also increases the first hour of hot water delivery while preventing overheating at the top of the tank.

Non-CFC Foam Insulation

You’ll experience less heat loss with this tank, thanks to the specialized insulation. Of course, this also results in less energy consumption, saving you money. Plus, it keeps the tank running more efficiently for longer so that you run into fewer water heater problems along the way.

Personal Perspective

I recently had a Bradford 55-gallon Hot Water Tank installed and after a short time, I noticed it started leaking a bit. However, with some tape, it worked great again. Unfortunately, my plumber informed me that there have been many issues with these tanks this year, and it turned out that mine had an anode failure due to the wrong construction material, causing damage to the interior tank. Bradford White only offered a minor repair solution and didn't acknowledge the poor manufacturing that led to further damages. I wish I knew this beforehand, as my previous Rheem tank lasted 20+ years without any issues. By this time next year, I'll have been dealing with more problems from this Bradford White Hot Water Tank, according to my plumber's recent experiences.

Rheem Residential Electric Water Heater

Best for Energy Efficiency

Electric water heaters are usually kinder to the environment than gas, but only if they’re energy-efficient. This 50-gallon residential heater from Rheem is currently one of the best electric water heaters for energy efficiency.

It has an Energy Factor of 0.93, indicating that it will be kinder to the environment than some other options.

Its useful features include a temperature protector to prevent overheating, an automatic thermostat, and a wide temperature range.

What We Like

Versatile Use

Whether you want to use it at home or work, this heater can be installed in a variety of locations.

Over-Temperature Protector

This heater’s energy efficiency is enhanced by its over-temperature protector. The heater limits water temperature to 160°F, at which point it will cut off. This prevents overheating, which reduces energy waste.

Good Temperature Range

The heater offers a generous heat range from 120-160°F. This allows you to choose your ideal temperature without the water becoming scaldingly hot.

What We Don't Like

Possible Leaking Issues

Some customers have complained that this tank leaks. This occurs around the top threads where the heating elements are located.

Not Very Durable

You can usually expect a large home appliance such as a heater to last around a decade. However, some customers complained their heater only lasted a few years before needing repairs or replacement. Others have said that it was showing signs of wear after just a few months.

Community Feedback

My experience with the Rheem water heater has been nothing but frustrating. When I initially purchased the top-of-the-line model in early 2022, I was disappointed to find myself needing to replace the control board within just a month. Unfortunately, the troubles didn't end there, as I found myself without hot water once again in less than five years. To make matters worse, when I tried to contact their support team for help, I was met with unhelpful and dismissive responses. Just one week before the warranty expired, I discovered that the upper element had burned out, and after spending two hours on hold with customer service, I was informed that they were closed. In conclusion, my experience with this Rheem water heater has been highly unsatisfactory, and I would not recommend purchasing their products.

A.O. Smith GPVL-50 ProMax Gas Water Heater

Best for Fastest Recovery Rate

If you’re looking for a powerful gas water heater, this unit from A.O. Smith is worth considering. It is Energy Star qualified and designed to optimize efficiency, with a uniform energy factor of 0.72.

It boasts a 50-gallon water tank that’s heated using a 40,000 BTU burner. This heater can provide enough hot water for a family of five or more. It produces enough hot water for a 33-minute shower, or three simultaneous showers.

Rather than the usual standing pilot ignitor, this unit has a hot-surface ignitor. This is far more reliable and durable and reduces energy consumption.

Another positive is the rotatable blower outlet. This can be adjusted to three positions, which makes installation a bit easier.

What We Like

Provides Lots of Hot Water

This water heater is capable of providing enough hot water for an 80-gallon tub. That’s plenty for an average family of four people.

Recovery Rate of 44.7 Gallons per Hour

This is one of the quickest recovery rates we have seen in a while. A 44.7 gallon per hour rate in a 50-gallon tank is remarkably fast.

Outlet and Inlet Heat Traps

Every year, a huge amount of heat escapes through pipes, resulting in energy waste. These fitted heat traps along the inlet and outlet mean you won’t need to worry about wasting energy. The heat stays inside the tank, where you need it most.

Three Position Outlet Blower

A three-position outlet blower is an extra feature that might seem unnecessary until you need it. By being able to turn this outlet, it becomes far easier to install the water heater in almost any location.

What We Don't Like

Noise When the Exhaust Fan Starts Up

This isn’t a major flaw but users reported that it makes some noise when the exhaust fan starts up. Fortunately, this stops quickly once the fan is up to speed.

First-Hand Impression

I've recently had an A.O. Smith 40-gallon water heater installed, and overall, I'm quite satisfied with its performance. The water heater provides a consistent temperature stream, which is not always the case with other models. However, I must mention that it did spring a leak around the bottom after six and a half years, and I had to replace it at an additional cost. While I enjoy the efficiency of this water heater, I can't help but feel that manufacturers could work on extending the lifespan of their products.

A.O. Smith ProMax Short 50-Gallon Electric Water Heater

Best for Easy Maintenance

This electric water heater is ideal for anyone who wants a unit that is easy to maintain. This heater from A.O. Smith will provide enough hot water for two showers running simultaneously, or one 26-minute shower.

One unique feature is the Dynaclean diffuser dip tube. This is essentially a power cleaner that reduces the build-up of sediment and lime.

This feature is perfect for anyone who doesn’t have the time to maintain their water heater. The Dynaclean diffuser also maximizes the outlet flow, delivering hot water faster.

On the inside of the tank, A.O. Smith fitted a CoreGard aluminum anode rod. These feature a stainless steel center that preserves the anode rods for longer than usual.

What We Like

Features a Dynaclean Diffuser Dip Tube

This is a unique and very useful feature. It power cleans the inside of the tank, eliminating lime and sediment.

Tank Fitted With a Coregard Anode Rod

This type of anode rod should outlive the standard type that usually has to be replaced every six years, if not sooner. A.O. Smith promises a long service life due to this durable material.

Insulated With Non-CFC Foam

Insulation is key when it comes to energy efficiency and this non-CFC foam will minimize energy consumption.

What We Don't Like

Requires a Plumber to Install

This is not something that everyone will be able to install. Contact your plumber and ask if they work with A.O. Smith water heaters. Some owners mentioned that their usual plumbers didn’t do so.

Gas vs. Electric

The fuel type and how much is consumed by a water heater will decide its annual operation cost. Heaters of the same size can still differ greatly in how much fuel they use. Although you can still find boilers that use oil, most modern top-rated boilers will use gas or electricity.

Gas Water Heater

A gas water heater consists of a tank with a burner at the bottom. As the water inside the tank cools, the burner is ignited to keep the temperature at a specific level.

A gas heater is fueled by either natural gas or propane. Today, most American households use natural gas.

Buying a gas-powered water heater is generally more expensive than an electric heater. However, the increased energy cost of an electric water heater can make it cost more money in the long term.


  • Faster recovery rate: Gas water heaters have a faster recovery rate. This makes them more convenient for family homes.
  • Heats quickly: The heater should be able to heat a full 50-gallon tank in about an hour.
  • Works without electricity: A major advantage of a gas-powered heater is that it still works during power outages.


  • High initial cost: The initial cost is generally higher than with electric heaters. However, they can compensate for this with lower energy bills.
  • Requires regular maintenance: Maintenance is crucial with gas heaters. Failing to have your heater serviced could lead to increased wear and tear or, in severe cases, even a gas explosion.

Electric Water Heater

Electric water heaters are best suited to homes with less demand for hot water. Their recovery rate is slower than gas-powered units. On average, it will take an electric 50-gallon unit about 80 minutes to heat up.

An electric water heater consists of a tall tank with two large coils inside. The coils resemble those found in electric ovens.

One coil is near the bottom and one close to the top of the tank. The two coils heat the water simultaneously, accelerating the process.


  • Dry fire protection: Dry fire protection means the upper heating element can detect whether or not it’s surrounded by water. If it can’t detect water, the heating element will shut off to prevent the heater from burning out.
  • Space-saving design: Electric water heaters are generally smaller than gas boilers. This is because they don’t require venting and exhausts.
  • Easy-to-use: Using an electric heater is a simple matter of plugging it in and setting the temperature.


  • High running cost: Electricity is generally more expensive than natural gas or propane. This makes an electric water heater more expensive in the long run.
  • Long recovery time: Electric heaters take longer than gas-powered heaters to recover. If your home has a high demand for hot water at specific times, it might be unable to keep up.

Things to Consider When Choosing a 50-Gallon Water Heater

Once you have decided on a gas or electric heater, there are some other points to consider.

First Hour Rating

It is important to consider the first-hour rating of the heater you’re considering. The first-hour rating describes the performance ability of your water heater (1).

This is calculated using the following formula:

Tank capacity x .70 + recovery time = first-hour rating.

A first-hour rating could look like this:

50-gallon tank x 0.7 + 55 = 90 gallons first hour rating.

0.7 represents 70 percent of the water heater’s capacity. As you use warm water in your home, new cold water enters the tank, diluting the hot water inside.

The water heater’s thermostat senses this temperature change and begins heating the water again.

The first-hour rating is significant because it helps you determine if the water heater is powerful enough. If your water heater is too small, you could run out of hot water before finishing your shower. On the other hand, if your heater is too large, you could waste money heating more water than you will use.

Simultaneous use is an important factor to consider. You need a water heater that will fulfill your needs and those of your housemates. This means it might need to provide hot water to multiple outlets at the same time.

This is especially true for homes with a dishwasher or washing machine without an internal heater. These appliances rely on your heater for hot water.

When searching for a new water heater, determining the first-hour rating doesn’t require a mathematician. The EnergyGuide label on the unit will display its first-hour rating.

Consider these points to decide which first-hour rating will suit you best:

  • Time of day: Think about the time of day when your household uses most of its hot water. This doesn’t need to be specific but try to determine whether it’s morning, afternoon, or evening/night. Keep in mind how many people live in your house.
  • Average gallons: Next, you should try to figure out the approximate amount of gallons you use during peak hours.
  • Choose a tank: Once you have the approximate amount of gallons used by your home, you can use this number as a guide and find your ideal water heater.

Energy Factor

The energy factor of a unit is determined by the amount of hot water produced per unit of fuel consumed on an average day. The energy factor describes the energy efficiency of the unit (2). 50-gallon water heaters should have an energy factor of at least 0.62.

Energy Star

Not all water heaters will have an energy star. However, a 50-gallon water heater with a star is on average 15 percent more efficient than a standard unit (3).

How Much is a Good 50 Gallon Water Heater?

In general, you should expect to pay in the region of $1,000 for a modern electric water heater and $1,200 for a natural gas equivalent. Although gas heaters are more expensive, natural gas is currently cheaper than electricity so your energy bills will be lower, effectively canceling this out.

How Long do Water Heaters Last?

On average, a new water heater should last you about a decade, ranging between eight to twelve years. This can vary greatly depending on how frequently you use the heater and how well it is maintained. Although some companies offer lifetime warranties, you will usually need to pay to replace parts after six years.

Is a 50 Gallon Water Heater Good?

A 50-gallon water tank will usually be large enough to fulfill the water demands of a four-person household. It should be able to supply water for three showers. You can get a rough estimate of how large your tank should be by adding 10 gallons per household member, so a family of seven might need an 80-gallon tank.

How Many Showers Can You Take With a 50 Gallon Water Heater?

If you have a 50-gallon water heater, you can take between three and five showers. But, a few variables could change the answer to this question.

Considering that a typical shower uses 17.2 gallons of water, it is typically possible to have enough hot water for up to five persons to take showers within an hour.

With a water heater that has a capacity of 50 gallons and a temperature setting ranging from 120 to 140 degrees Fahrenheit, you will be able to take a shower for approximately 17 minutes until there is no more hot water, and that could be enough for only two people.

How Long Does It Take for a 50 Gallon Water Heater to Warm Up?

It takes approximately 1 hour and 20 minutes for a 50-gallon water heater with elements rated at 5,500 watts and set to a temperature of 120 degrees to heat water that is brought into the unit at 60 degrees.

When water with a temperature of 40 degrees is introduced into the same tank, the process of heating the water takes 1 hour and 47 minutes.
