Writen by Ronald Brown

Fact checked by Natalie Bridges

If you want a more energy-efficient water heater for your family of five, only the best 50 gallon electric water heater will do. It costs less to purchase, is more straightforward to install, eco-friendly, and hassle-free to maintain. You can never ask for a better combination.

best 50 gallon electric water heater

Shopping for the most trusted 50-gallon electric water heater is not always easy because almost all products look similar. Therefore, buyers must assess each prospect and determine the following crucial factors.

  • First-hour Rating: Electric products heat the water more slowly than gas-powered units. Hence, buyers must be selective when shopping, opting only for 50-gallon electric heaters capable of producing more hot water in the first hour of operation (i.e., 70 gallons vs. 60 gallons).
  • Recovery Rate: Nobody wants to wait in the shower for the water to heat after someone else use it. A 50-gallon electric water heater’s recovery rate describes how much hot water it can produce in an hour with continuous hot water consumption. In short, it is recommended that buyers pick a water heater with a higher recovery rate (i.e., 60 gallons per hour vs. 45 gallons per hour).
  • Uniform Energy Factor: As a rule, the closer a 50-gallon electric water heater’s UEF value is to 1.0, the more energy efficient it is. Most experts recommend an energy efficiency rating of at least 0.90 to optimize the product’s water-heating capabilities without jacking up your electric consumption.

The only thing you need now is to learn how to choose the top-tier 50 gallon electric water heating system for your household.

Top-Rated 50 Gallon Electric Water Heater Reviews

1. AO Smith ENS-50 Electric Water Heater

Most fifty-gallon electric water heaters are tall, measuring about 5 to 5.5 feet high. Getting the A.O. Smith ENS 50 ProMax should never be an issue, even if you decide to place it in a 5-foot vertical space.

This 50 gallon short electric water heater happens to be only 49.25 inches high. With a 23-inch diameter, the A.O. Smith ENS 50 ProMax makes it more compact than other electric water heater systems on the market.

I like this product’s first-hour rate of 62 gallons. You can have more exciting showers while your wife is busy doing the laundry and your kid is running the dishwasher. It heats and recovers fast enough that running out of warm water will be the least of your worries.

I love the DynaClean and CoreGard anode rods with stainless steel core because they complement each other in improving the tank’s corrosion and limescale-formation resistance. The DynaClean technology also ensures you get maximum output from your faucet or showerhead.

The heater only uses two 4,500-watt heating elements with a maximum wattage rating of 6000 watts. You will never have to worry about costly energy use.

My only comment is its energy factor rating of 0.92. I have seen some electric water heaters with a UEF of 0.96. While this water heater is easy to install, I still recommend getting a professional to do it for you. It requires a dedicated 240-volt system for it to run efficiently and safely.

Overall, I love the A.O. Smith ENS-50 ProMax because of its compact size and superior hot liquid output. I think it is the top-rated short 50-gallon electric water heater you can buy.

Using these water heaters will only cost you about $500 in your energy expenditures every year. Some systems do worse, costing you about $800 to $1,000 annually.

The Rheem MR50245 Marathon Tall unit’s 61-gallon first-hour rating is also commendable, enabling you to enjoy fun activities with your family.

The tank’s construction also gives the heater cost savings in the long term. Thanks to the polybutene tank, it resists corrosion better than other systems, extending its service life by a few years.

What Is The 50 Gallon Electric Water Heater/ Who Is This For


The top-tier 50 gallon electric water heating system uses electricity to heat an element that raises the temperature to the desired level.

Electric hot water heaters are suitable for households with three bathrooms or those with a washing machine and a pair of baths. In general, a person uses about 10 gallons of warm water during a shower. Dishwashers can use about 10 gallons and washing machines need 20 or so gallons.

Advantages And Disadvantages Of Using A 50 Gallon Electric Water Heater

The best 50 gallon electric water heaters offer the following advantages.

  • These electric water heaters are ideal for small families, ranging from four to five members.
  • They are cheaper to buy upfront than gas water heaters while also lowering installation costs.
  • Heaters that use electricity are easier and faster to install and maintain than gas water heaters. A gas heater requires complicated ductwork to vent gas safely.
  • Electric-powered water heaters are friendlier to the environment than gas heaters because they do not emit noxious gases into the atmosphere. A gas water heater is not eco-friendly.

Fifty gallon electric water heaters can also have the following disadvantages.

  • They take more time to heat than gas water heaters.
  • A gas heater costs less to operate, giving electric appliances higher operating costs.
  • Electric devices will not run in case of a power outage. Gas water heaters do not have such problems.

50 Gallon Electric Water Heater Buying Guide


Buying the best 50 gallon electric heating system for your family’s water supply requires looking at several factors.

  • Energy Factor

Ideally, you will want electric water heaters 50 gal units with a higher Uniform Energy Factor or UEF. This number gives you an idea of the product’s overall energy efficiency. Many people consider a UEF of 0.90 to be sufficient. However, it would be better to get a product with an energy efficiency rating close to 1.0.

You can see electric water heaters with a UEF of 3.4 to 3.9. These products are hybrids, allowing you to operate an energy-efficient heat pump that utilizes warm air from the external environment.

  • First-hour Rating

Water heaters have a maximum draw equivalent to 70 percent of their tank capacity. The figure accounts for the simultaneous cold-water inflow and hot-water outflow. As such, if you have the most trusted 50 gallon electric heater mated to your plumbing system, you can expect its draw capacity to be only 35 gallons.

Thirty-five gallons is barely sufficient for the whole family. That is why you should look at the system’s first-hour rating. It provides you a good idea of the appliance’s ability to deliver hot water for a full hour.

We recommend getting a product with a high FHR. For example, you can pick an appliance with a 70-gallon FHR instead of a 60-gallon FHR product.

  • Recovery Rate

Every time you have a hot shower or run the dishwasher, your appliance dispenses hot water. It also needs to replenish the fluids delivered to your fixtures by running cool water into the tank and heating it.

It may take a while for the system to provide you with sufficient hot water because of mixing cold and hot liquid in the tank. That is why you must check the product’s recovery rate, expressed in gallons per hour.

A product’s recovery rating paints a picture of how much hot water you can expect it to provide you every hour of continuous use. Like the first-hour rating, it would be in your best interest to choose a product with a high recovery rate.

  • Installation

While electric heaters are easier to install than gas units, some brands do require professional installation. They may provide such a requirement to secure the warranty, while others may only want the top-tier installation for their clients.

  • Warranty

The top-rated 50 gallon heaters come with a minimum of six-year warranty. The more extended the warranty, the more confident you are about the product’s quality and performance.

Frequently Asked Questions (FAQs)

What is the average cost of a 50 gallon electric hot water heater?

The average 50-gallon electric water heater costs $500, although prices vary across brands and models. A similarly-sized electric tankless water heater can set you back by $1,200 to $3,500.

Although electric water heaters seem cheap, they are more expensive to operate than gas-powered units. Electric products consume about 1125 to 4000 watts each year, while gas ones only use about 214 to 230 therms annually. In the US, natural gas costs 92 cents per therm. Meanwhile, electricity costs 16.7 cents per kilowatt-hour.

Suppose you use the 4500-watt A.O. Smith Signature Lowboy electric water heater for only three hours daily. In that case, you will consume 13.5 kWh daily or 4,927.5 kWh annually. This electric consumption translates to $822.90 yearly.

If we have a high efficiency gas water heater that uses only 215 therms annually, you can expect to pay only $197.80 yearly. Even the highest-rated electric unit cannot match a gas-powered heater’s long-term cost-effectiveness.

Are new 50 gallon electric water heaters more efficient?

Yes, new 50-gallon electric water heaters are more efficient than products of yesteryear. As pointed out by Consumer Reports, new water heaters of 55-gallon and below are four percent more efficient than earlier iterations.

However, experts agree that the heater’s capacity does not necessarily affect its efficiency. You might think a 40 gallon electric hot water heater is more energy-efficient than a 50-gallon unit, but that is not always the case.

Homeowners must look at the electric water heater’s UEF rating to determine which is more efficient. For example, a 50-gallon electric water heater with a 0.95 UEF rating is more efficient than a 0.75-rated 40-gallon model.

Is a 50 gallon electric water heater enough for a family of 4?

Yes, a 50-gallon electric water heater is enough for a family of four. However, this water heater’s adequacy depends on the household’s peak hot water consumption in an hour.

Let us assume all four family members shower for 10 minutes and use about two gallons per minute (total = 20 gallons each). If they shower successively, the family will consume 80 gallons in around 40 minutes.

Suppose the electric water heater has a first-hour rating of 70 gallons. In that case, this water-heating system may not be sufficient to meet the family’s hot water demands.

Minimizing hot water usage during showers (i.e., use hot water intermittently) can help make the 50-gallon water heater sufficient to meet the four-member family’s needs.

Is Rheem or Bradford White better?

If we compare water heaters from Rheem and Bradford White, the former will come out on top among ordinary homeowners due to their affordability. Meanwhile, professional plumbers pick Bradford White because of its centuries-old dedication to only the highest possible quality.

Therefore, determining whether Rheem or Bradford White is a better option requires detailed comparisons between the two brands.

Bradford White predates Rheem by 44 years, having been established in 1881. Professionals revere Bradford White’s unconditional commitment to energy-efficient, durable, and safe water heaters. The brand’s tagline, “Built to be the Best,” answers the question, which brand of water heater is the most reliable?”

In addition, Bradford White offers many revolutionary electric water heater technologies, including ICON Intelligent Control millivolt technology, Vitraglas enamel lining, and HydroJet Total Performance System.

Not to be outdone, Rheem also has several technologies up its sleeve. Homeowners love the EcoNet Wi-Fi connectivity. It is also more affordable, allowing Rheem to enjoy higher electric water heaters ratings than Bradford White among budget-conscious homeowners.

As for their warranties, both brands cover their electric water heaters for six to ten years. However, Rheem ups the ante by offering a 12 year warranty on its hot water cylinder.

What are the most trusted 50 gallon electric water heater brands?

AO Smith and Rheem are neck and neck when it comes to reliable, high-performance, and energy-efficient 50 gallon heaters. It is not surprising these brands are two of the most trusted on the market. Other noteworthy most trusted 50 gallon electric heater brands include Bradford White and Reliance.

Is AO Smith better than Rheem?

Rheem relies on its 95-year tradition of excellence to offer you a wide range of heating technologies. Their products are also more readily available.

On the other hand, A.O. Smith hinges on its ingenuity to wow its customers. The brand was the first to introduce glass-lined tanks in the mid-20th century. It is also famous for its exceptional customer service, a trait you can read in one electric hot water heater review after another.

Comparing both brands’ 50-gallon water heater offerings, we can say that AO Smith HPTU-50N Voltex edges Rheem PROE50 T2 RH95 in terms of Unified Energy Factor (UEF) rating (3.42 vs. 0.95).

How long should a 50 gallon electric water heater last?

Check your owner’s. Your unit should last between eight and twelve years, depending on how much care you put into its maintenance and the type of water that it heats. A high water-hardness level can shorten your water heater’s lifespan.

How long does it take a 50-gallon electric water heater to heat up?

It depends on the cold-water temperature, the water heater’s power rating, and the desired temperature.

Suppose you have a 5,500-watt water heater, and you want to heat the 60-degree Fahrenheit water to 120 degrees Fahrenheit. In that case, your 50-gallon water heater can take 80 minutes to heat the water to your preferred temperature.

If the temperature is 40 degrees Fahrenheit, a similar water heater setup can take about 110 minutes to complete. A 70-degree Fahrenheit temperature can reach 120 degrees in about 66 minutes.

How to care & clean?

Caring for 50 gallon water heaters requires regular cleaning and maintenance, including draining and replacing the tank’s contents.

You may also need to check the fittings and valves, such as the drain valve and the TPR valve. If you do not know anything about electricity, having an electrician check on your electrical connections can safeguard your investment. He may have to check the anode rod if it is time for a replacement.

Clean the tank’s exterior regularly. Dirt and dust can accumulate on surfaces and can lead to corrosion or damage. Keep your water heater’s surroundings free of clutter, making it easier for you to notice any problems.


The best 50 gallon electric water heater lets you enjoy better energy savings than a conventional gas system. It is friendlier to the environment, more straightforward to install, and worry-free to maintain. Above all, it can bring more enjoyable showers and more efficient washings for your family of five.
