Factors to Consider when buying a 50 Gallon Electric water heater

Here are some of the crucial factors you should consider before settling on a specific electric water heater for your home

Energy Efficiency

When buying an electronic product, its energy efficiency should be one of the most important factors to consider. If you don’t want your electricity bill to shoot out the roof, you will have to find an efficient one.

The electricity consumption of water heaters is determined by several factors. These are:

  • The volume of water that is used for every shower. The more water used for every hot shower, the more electricity consumed.
  • Another factor is the environment you live in. If you live in colder temperatures, you will need more heating compared to a person living in warmer areas.

Uniform Energy Factor (UEF)

UEF is a metric used to measure the energy efficiency of a water heater. It is usually determined by the estimated usage of a water heater. A higher energy factor is usually recommended when picking out a water heater for your home. Most electric heaters range between 0.75 and 0.95.

It is, however, essential to establish that higher energy factor values do not always translate to lower operating costs, as it varies between different fuel sources.


Another vital aspect to consider when picking out an electric water heater for your home is the capacity. Some people will opt for a smaller tankless water heater that is more compact and efficient but rather expensive when compared to a storage water heater.

However, unless you are willing to spend on a tankless unit for every bathroom, these heaters cannot supply hot water to the entire house, especially if several people are using it. This list features 50-gallon capacity electric water heaters that are compact enough for a small home and large enough to serve a household of 4 to 5 people.

First Hour Rating (FHR)

The first-hour rating determines the performance abilities of a water heater within the first hour of use when recovered to the thermostat setting. To calculate the FHR, you multiply your tank’s capacity by 70% and add the recovery rate, which is how quickly lost water going out of the tank is replaced. The 70% usually accounts for the heat loss caused by cold water entering the tank.

Space Requirements

When choosing an electric water heater, you want to find one that will perfectly fit into your home without having to make any costly build changes. Electric water heaters are more compact than other heaters. This size makes them ideal for people with limited space in their homes.

Ease of Installation

Usually, installing a water heater is a simple task. It can be accomplished by any enthusiastic person interested in DIY projects. However, it is always recommendable to have or get someone with basic plumbing and electrical knowledge. If you are uncertain about how everything works, you should get a professional to help you with installation to avoid any unnecessary mishaps.

Safety Features

Water heaters tend to be safe for use. However, you must be fully aware of all the risks they pose and the safety features of the storage water heater. Ensure that your water heater has a safety valve that can be opened to relieve pressure if the temperature or pressure gets too high. This clever feature

prevents the heater from blowing up if anything goes wrong.

Warranty & After Sales Service

When picking out an electric water heater for your home, it is always recommended to go with the renowned brand name with a reputation of offering high-quality products and after-sales services. Some reputed brands offer installation, after-sale services, and warranties on both the tank and parts. This will give you peace of mind, and save you a lot of trouble and money.

Pros & Cons of Electric Water Heaters

There are several reasons why you should consider an electric water heater for your home over a gas water heater. Let’s look at some reasons why you should opt for an electric water heater for your home.


Lower initial costs

Electric water heaters tend to be more affordable than any other of their counterparts available in the market today. The cost of installation is one of the most essential factors determining how much you will have to pay for the water heater upfront.

Gas heaters usually require additional piping and ventilation system for the exhaust generated during combustion. On the other hand, electric heaters do not require any additional infrastructure for installation.

Easy & convenient to use

Electric water heaters are easy to operate, and in most cases, it just involves flicking a switch. Since they run on electricity alone, you will never have to worry about late gas deliveries ever again.

Most heaters will feature a large display with a temperature control system that helps you keep the temperature in check and adjust it with ease when necessary. Other brand names will even let you set the maximum and minimum temperature as well.

Compact size

Electric water heaters come with beautiful advanced designs that are much more compact than other heating systems, making them a favorite for many homeowners across the country.


More expensive in the long run

Although electricity water heaters are cheap to acquire, they tend to be much more costly in the long run than many of their counterparts. This is due to the simple fact that electricity is more expensive than other fuels. Heat pumps and solar pumps are the most effective solutions for home water heating.

Power Shortages

This might not be a significant point of concern, but it is still worthwhile to consider every little thing while at it. In case of a power outage, you will not have access to hot water until the power comes back on.


50-gallon water heaters are ideal for an average-sized family of four or five people. However, it takes much more than size to pick out the correct unit for your home. It is essential to establish how much hot water your home requires.
