Never worry about running out of hot water again with the best 50-gallon water heater.

Is your current water heater running on its last legs? Or is your family growing and it’s time to upgrade to a larger water heater? We’ve gathered the five best 50-gallon water heaters for you.

A 50-gallon tank is a good size for families, or people using multiple sources of hot water at the same time. But first, let us help you make an informed decision. Below are some points to consider before spending your hard-earned money.

First Hour Rating – Why It Matters

There are other things to think about besides the tank size (1).

One of the most important things to take into account is the first-hour rating of the heater you’re considering. The first-hour rating is the performance ability of your water heater (2).

It’s a calculated amount using the following formula: Tank capacity x .70 + recovery time = first-hour rating. It 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. This is because, as you’re using hot water in your home, new cold water is entering the tank. The colder water dilutes the hot water within the tank.

The water heater’s thermostat senses the change in water and then it begins heating again.

The first-hour rating matters because it helps you to determine if the water heater has the right abilities for you. If you get a water heater which is too small, you’ll run out of hot water before finishing your shower. However, if your heater is too big, you could be wasting money on heating water no one uses.

Simultaneous use is an important factor to consider. You need a water heater that will fit your needs. And, it should be able to provide hot water for multiple sources at the same time.

This goes especially for homes with a dishwasher or washing machine without an internal heater. The appliances then rely on your heater for hot water.

When you’re searching for a new water heater, figuring out the first-hour rating doesn’t require you to be a mathematician. The EnergyGuide label on the unit will tell you its first-hour rating.

However, you could consider a few points to determine which first-hour rating will suit you:

  • Time of day: Try to figure out what time of day you use the most hot water. It doesn’t have to be specific, but try to determine whether it’s morning, noon, or evening/night. Keep in mind how many people live in your house as well.
  • Average gallons: Next you’ll want to try to figure out the approximate amount of gallons you use during peak hour.
  • Choose a tank: You should now have the approximate amount of gallons your home requires. You can then use this number as a guide when finding the right water heater.

Gas or Electric

The fuel or power of the unit will ultimately determine its annual operation cost. It will also determine its size and energy efficiency. Although you can get some boilers that use oil, most boilers will run on gas or electricity and those are the two fuels we will focus on.

Both of these fuels have their pros and cons, so let’s take a closer look.

Gas Powered Heater

A gas water heater consists of a tank with a burner at the bottom. As the water temperature within the tank drops, the burner is ignited to bring the temperature back up.

The gas heater is either fueled by natural gas or propane. Most American households use natural gas.

Gas powered water heaters are generally higher priced compared to electric heaters. However, the running cost of an electric water heater can make the unit more expensive over time due to the cost of electricity.

  • Faster recovery rate: Gas water heaters have a faster recovery rate. This makes them more convenient for family homes.
  • Heats considerably quickly: The heater should be able to heat a full 50-gallon tank in about an hour.
  • Works without electric hook up: A huge advantage of a gas powered heater is that it still works during a power outage.
  • High initial cost: The initial cost is generally higher than with electric heaters. That said, they usually pay for themselves in savings on utility bills over time.
  • Requires frequent maintenance: Maintenance is crucial with gas heaters. Failing this could result in wear and tear or a gas explosion.

Electric Water Heater

Electric water heaters are best suited for a home with less demand for hot water. Its recovery rate is slower than gas-powered units. 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 the ones you find in electric ovens.

One coil is close to the bottom and one close to the top of the tank. The two coils will heat the water from the top and bottom at the same time, which speeds up the process.

  • Dry fire protection: Dry fire protection means the upper heating element can sense if it’s surrounded by water or not. If it isn’t surrounded by water, the heating elements will shut off to prevent the heater from burning out.
  • Space-saving design: Electric water heaters are generally smaller and more compact than gas boilers. This is mainly because they don’t require venting and exhausts.
  • Easy-to-use: They’re simple to use since it’s only a matter of plugging them in and setting the temperature.
  • High running cost: Electricity tends to be more expensive than natural gas or propane. This makes an electric water heater more expensive in the long run.
  • Long recovery time: An electric heater takes longer than gas-powered heaters to recover. If you’re home has a high demand for hot water at a certain time, it might not be able to keep up.

Other Things Worth Considering

After deciding between gas or electric, there are two other points worth a thought. These can further help you to find a water heater which not only suits your needs but is also energy saving.

  • Energy factor: The energy factor of a unit is determined by the amount of hot water produced per unit of fuel consumed during a usual day. The energy factor decides the energy efficiency of the unit (3). 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, the 50-gallon water heaters with a star are 15 percent more efficient than standard units (4).

2. Rheem Marathon Tall Electric Water Heater

Best for Well Water

Rheem MR50245 Marathon Tall Electric Water Heater, 50-Gallon

Around 15 percent of people living in the U.S. get their water from domestic wells (5). The issue with this is that the water is usually colder and needs more power to heat sufficiently. What you need is a water heater that can provide such power, so take a look here.

This electric water heater from Rheem is made from non-metallic fiberglass material, resistant to corrosion and rust. It has immense strength thanks to the several layers of filament wound fiberglass around the tank.

Better still, it has an energy factor of 93 percent. This is primarily due to the Polyurethane Environfoam insulation that minimizes standby heat loss. It captures the heat, which keeps the water hot for longer.

  • Low energy consumption.
  • Well insulated for minimum heat loss.
  • Tough molded exterior.
  • Lifetime warranty on tank, six-year warranty on parts.
  • Parts are hard to replace.

Why We Love It

Low Energy Consumption

Thanks to the insulation, the unit doesn’t consume a lot of energy. It keeps the leftover water hot for longer, so next time you need it, less energy is used on reheating.

The unit also utilizes electric immersion elements to heat the water. These elements transform 100 percent of their energy to heat. Additionally, due to the foam insulation, less energy is wasted reheating present water.

In all, the tank can hold 50 gallons of water. And, it has a recovery rate of 21 gallons per hour from a 90 degree Fahrenheit rise.

Well Insulated for Minimum Heat Loss

Rheem insulated the tank with Polyurethane Environfoam, which traps the heat, so it doesn’t escape. This also enables it to heat up faster, having a recovery rate of 21 gallons per hour.

Tough Molded Exterior

Although it’s made from a non-metallic material, the tough molded exterior keeps the unit safe from outside dangers. This is an especially helpful feature if you have kids.

You may also notice that this tank has a bowl-shaped bottom. If you wonder why, it’s so the water can drain completely. No need to worry about old, unsafe water building up at the bottom.

Lifetime Warranty on Tank, Six Year Warranty on Parts

The unit comes with a limited lifetime warranty — six years on the parts. By this, Rheem means that it only adheres if you install it in your own home. The general limit on water heater warranties is about six years, so this is a definite plus.

Keep In Mind

Parts Are Hard to Replace

Although you get a six-year warranty on parts, a few users pointed out that it was difficult to get a hold of support. The issue seems to be that Rheem doesn’t have the best customer service.

This is, of course, not a huge issue if the unit works as it’s supposed to. However, those who exceeded the six-year warranty had a hard time finding the parts in local stores. You’ll most likely have to go through your plumber.

If you’re looking for a powerful gas water heater, then look no further. This example from A.O. Smith is worthy of consideration. It is Energy Star qualified and designed to optimize efficiency, with a uniform energy factor of 0.72.

It has 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 more than five people. It can produce enough hot water for a 33-minute shower, or three showers simultaneously.

Instead of the standard standing pilot ignitor, this unit has a hot-surface ignitor. This is much more reliable and durable, plus, it reduces energy consumption.

What we also love is the rotatable blower outlet. You can rotate it to fit three positions and that makes installation a bit easier.

  • Provides lots of hot water.
  • Has a recovery rate of 44.7 gallons per hour.
  • Outlet and inlet heat traps.
  • The three position outlet blower.
  • Creates some noise when the exhaust fan starts up.

Why We Love It

What this water heater is capable of is amazing. It can provide enough hot water for an 80-gallon tub! It’s plenty for an average family of four.

Has a Recovery Rate of 44.7 Gallons per Hour

This is one of the fastest recovery rates I’ve seen in a while. 44.7 gallons per hour in a 50-gallon tank — amazing!

Outlet and Inlet Heat Traps

Every year, a massive amount of heat escapes through the pipes, resulting in energy waste. With these fitted heat traps along the inlet and outlet, you don’t have to worry about wasting energy. The heat is well secured inside the tank, where you need it.

The Three Position Outlet Blower

A three position outlet blower is just one of those extra features that seem unnecessary until you have it. It makes it super easy to install the water heater in nearly all locations.

Keep In Mind
