Things to Consider

During winter, even the bravest start shivering. This is when any water-related task in the house, such as laundry, washing dishes, and bathing, needs some effort.

Using cold water for such tasks will freeze your nerve. And if you have a large family, this is where a large capacity water heater comes in handy.

A water heater is a reliable product that will help you get through the cold season. We have provided the guide below to make your process seamless.

How to use 50-gal electric water heaters


A 50-gallon is a common tank used in most homesteads. It’s primarily used for domestic tasks such as laundry, washing dishes, and bathing.

A 50-gallon electric heater can supply hot water for 4-5 people, hence ideal for a large family. Primarily, it takes 17.2 gallons of water for an average shower. Meaning five people can bath with hot water within an hour.

An electric water heater offers a myriad of benefits to the homeowner. However, before installing an electric water heater, check the brand, features, and even the price to ensure the product suits your needs.

Some of the benefits include:

  • Lower Initial Costs

Undoubtedly, there are several water heaters on the market, but an electric water heater is an affordable option. Regardless of the power it uses, the cost will largely depend on the type and size. For instance, a conventional tank water heater is cheaper compared to a tankless water system.

For gas water heaters, additional piping and ventilation system are required. When it comes to electric water heats, no in-home infrastructure is needed.

This makes the installation process easy and inexpensive.

  • Safety

Electric water heaters are safe solutions to heat your water. A gas heater is prone to gas leaks, which can cause a fire. Although electric water heaters have their safety concerns, you cannot experience gas leakage with these products.

With an electric water heater, you only switch off if you do not notice any glitch. Hence, making them safe to have them at home.

  • Availability

Almost every home is connected to an electric grid, meaning there is a readily available electricity source. Any home tied to an electric grid can actively have an electric water heater.

  • Efficiency

Every homeowner desires to cut down on electric bills. And a water heater can save you some bucks. When choosing an electric water heater, check the energy factors. The EF number indicates the effectiveness of the product in producing hot water.

  • Space Requirements

Of the greatest features of an electric water heater is its ability to get installed in spaces. For a gas water heater, you’ll need at least 6-18inches of ventilation, meaning the tank cannot get installed in crawlspace or small closest. This is not the case with electric water heaters, which can get installed in confined spaces.

How does an electric water heater work?


Electric water heaters are familiar appliances in most homes. They’re big metal cylinders often consigned to a basement or laundry room. Today, there are newer and distinguishable features that make these appliances work more efficiently.

what makes them unique is how they exploit heat to deliver hot water to your faucet without fuss.

An electric water heater is composed of various elements that work together to deliver hot water to your home.

The thermostat is designed to control temperatures inside the tank. The recommended temperature by most manufacturers is 49-60 degrees Celsius. Setting the appliance to a lower temperature will save energy.

To ensure you have the right product, ensure it’s of the right size. The first-hour rating will help you know the amount of hot water (in gallons) the heater supply per hour.

The dip tube delivers water to water lines located at the bottom of the water heater. This is where the water starts to warm up. Then a heating mechanism- which is either an element or burner, will stay on until water gets to the desired temperature level.

Water will heat and rise above the cold water. The heat-out pipe is where hot water exit through to your home faucets. The secrete of an electric water heater of separating hot water from cold is the principle that heat rises.

How to maintain electric water heaters

An electric water heater will give you comfort that you need during the cold season. It’s, however, a huge financial investment that you need to choose and maintain wisely. With good care and maintenance, a water heater can last even up to 15 years.

You can do routine servicing without calling a professional. Ensure you switch off the circuit breaker. Do a mini-flush to prevent corrosion and rust, a task that will enhance energy efficiency. 

The sediment buildup is caused by hard water. To prevent such, use a water softener. Flush out the sediments and refill the tank again. Ensure the tank is full before switching the power on.

Mini or full flush will remove the scale buildup on heating elements. It will also eliminate hissing sound produced when the heating mechanism is covered with limescale.

To test the thermostat, use a multimeter. This is to ensure there is power flowing to the elements. also, tighten the loose wires. The anode rod also called a sacrificial rod, is made of steel coated with aluminum or magnesium. It can last for about five years or even more, only if it’s well maintained.

Simple regular checking of your electric water heater will prevent you from replacing the tank regularly. More so, it will last longer and maintains its lustrous look.

Price range

As electric water heaters come in different shapes and sizes, so is the price. on average, these units cost $100 to around $3,000. The price will depend on the tank capacity.

For 50-gallon water heaters, the price range between $400-$2,200. The initial installation cost will also affect the overall cost of a heater. Consult with your professional plumber to get the most affordable yet durable electric water heater.

When buying an electric water heater, you need to be extremely careful. First, you need to know what to consider. There are essential elements you must factor in to get the best electric heater. And finally, you must buy it from a trusted vendor. Here are pointers you should keep in mind before purchasing.

Energy efficiency with UEF

If you’ve ever bought a water heater before, then you must have compared standard efficiency, mid-efficiency, and high efficiency.

The UEF is used in measuring the energy efficiency of a water heater. This DOE’s newly developed metric is quite accurate. When the UEF is reading higher, the better the performance. The UEF should read about 2.00 or more.


Electric water heaters come in different dimensions. This means you can have taller or wider tanks. The dimensions will help you choose a product that will fit in your space perfectly. For instance, Rheem MR50245 Marathon measures 23.5 by 66.7 inches.

An electric water heater is an essential appliance at your homes. The heaters enable your home functions to run smoothly. Whether you want to wash utensils or take a hot bath, this is a vital piece of equipment.

Heaters come in different sizes, which affect their weight. when you come to a 50-gallon heaters, it will weight from 100 lbs and above.

These numbers can differ based on the model and material used. Regardless, expect a 50-gallon electric water heater to weigh somewhere approximately 160 pounds.

The Rheem MR50245 Marathon weighs 101.1 lbs, while A.O. Smith ENS-50 ProMax weighs 161 lbs. Both of these tanks have the same capacity but weigh differently.

Guarantees and durability

Warranties are essential features to check when choosing electrical products. Most of, if not all, electrical appliances are prone to faulty wiring, blowing up, or voltage surges.

This is why you’d need warranties on these products. Usually, electrical appliances have long term warranties.

For instance, Westinghouse WER062C2X045 comes with a limited lifetimes warranty on tank. So, why check on warranties? Warranties give you more trust in the product. It also means you will use the water heater without the worry of replacing it after one or two years.

Reading the warranties is tedious, but you need to understand what it covers and the situations they apply. You’ll realize some have warranties on parts while others don’t cover repairs.

Check if there is a money-back guarantee in case the appliance is defective.

Durability is another essential factor to consider. It’s affected by the material used. Stainless steel is a sturdy, durable material.

Ease of installation

Installation of electric water heaters is not as hard as you might think. You only need to have some plumbing basics, tools and follow instructions to the latter.

However, this is not everyone’s ideal choice. a simple mistake might lead to voltage surges and wire shortages. If you don’t want to incur installation costs, ensure you follow the instruction guide step by step.

In case it becomes hard for you, you can consult a professional. Some manufacturing companies offer free installation. Electric water heaters come with a detailed instruction manual to guide to install.

Ease of use


The best electric water heater should be easy to use. it requires you to find a circuit breaker and turn it on. ensure the tank is full before switching on. draining and flushing the tank should be easy for cleaning it out. once the tank is full, you can then turn on the circuit breaker.

Anode rod

Water heaters are prone to rust and have other water-related issues. They may have some trouble after several years of use. saltwater or hard water will even worsen the situation. The tanks are always submerged in water, making them corrode or rust.

This is where the anode rod comes in handy. A good anode rod will protect the water heater by attracting harmful ions. That’s why it earned the names, sacrificial rod. It boosts the lifespan of the tank.

Bradford White BWC RE350T6-1NCWW comes with a protective magnesium anode rod. The material used provides unmatched durability.

Extra features

There are other features that you should pay attention to. Look for a model engineered with high first-hour recovery in terms of gallons per hour. It helps you to know that the tank will provide enough hot water for your home usage.

The heating mechanism is an essential part of a water heater. The elements should be made of high-quality material such as stainless steel for durability and protection from dry-firing.

You should also consider the insulation R-value. Always choose a unit with a high insulation value. Lower value means the product is less efficient, leading to high operations costs. And since you’re looking for ways to minimize the bills, a unit high insulation of about R-24 is highly recommended.

A reliable electric water heater is endowed with features such as high0-quality heating elements, dip tubes to minimize sediments, and a self-cleaning system. check all these advanced features to help you have the best unit at your home.


What size of breaker do I need for a 50-gal electric water heater?
Basically, an electric water heater needs a 240V circuit for serving the water heater only. The wiring involves a 30-amp double pole breaker and MC or 10-2 non-metallic cable.

How long does it take to heat 50 gallons of water?

There are several factors that can affect this, including water temperatures entering the unit and the type of heating element fitted in the unit.

Electrical water heaters have two things to help you determine the right answer to this question.

Recovery Rate- This is the amount of water that a heater can supply hourly, starting on an empty tank.

First Hour Rating(FHR) – It’s the opposite of the recovery rate. This is the amount of water in gallons a heater can supply per hour when it is full.

Is an electric water heater safer than the gas one?

Both gas and electric heaters have their risks. However, the electric heater is safer than the gas one. In an electric heater, you won’t have fuel leaking or explode. There are no combustible byproducts, making them safer than gas water heaters.
