Best 50 Gallon Electric Water Heater Reviews

1. AO Smith ENS-50 ProMax Short 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 rod 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 best short 50-gallon electric water heater you can buy.

What We Like
  • 62-gallon first-hour rate for better energy consumption
  • CoreGard sacrificial anode technology for improved corrosion resistance
  • DynaClean diffuser dip tube technology for maximum output
  • Low-wattage rating for better energy savings

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.

While this water heater is more than five feet tall, it is still a breeze to install. It has a brass drain valve that is easier to work with than plastic components.

I appreciate its energy factor and first-hour rating. I only wish the company also improved its 20-GPH recovery rate. Some systems can deliver up to 40 GPH. A few customers also complained about the cold-water air intake check valve’s durability. Worry not, as it comes with a limited lifetime warranty.

Overall, the Rheem MR50245 Marathon Tall heater remains an excellent choice for those who want a cost-effective water heater. It provides enough hot water for a family of five without ever breaking the bank.

I am not too fond of this electric water heater’s 21-GPH hot water recovery rating. I expected it to provide at least 30 GPH or more, given its energy efficiency. It is also taller than other brands, making installation a bit tricky if you do not have sufficient vertical clearance.

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

50-gallon-short-electric-water-heater

The best 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

electric-hot-water-heaters

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 is 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 its tank capacity. The figure accounts for the simultaneous cold-water inflow and hot-water outflow. As such, if you have the best 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 best installation for their clients.

  • Warranty

The best 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)
