If you’re looking for the best 50 gallon electric water heater, you’ve come to the right place. In this article, you'll learn about the benefits of large 50 gallon electric water heaters versus gas-powered heaters so you can determine which is best for your household.  

According to the US Energy Information Administration, approximately 12% of a household’s energy consumption is spent on heating water.  That’s more than refrigerating, lighting, and cooking combined. It's no wonder that there are so many households opting for energy efficient electric water heaters.

Why Choose a 50 Gallon Electric Water Heater?

There are a number of advantages that electric water heaters have over their gas-powered counterparts, especially among the 50-gallon tank size. For example, electric water heaters are easier to install because they do not require ventilation.

The best 50 gallon electric water heaters are high efficiency devices that provide excellent performance per kilowatt-hour of energy that it consumes.

With gas water heaters, only about 50% of the fuel energy required to power it actually reaches the point of use (e.g., is converted into hot water). Roughly half of the power used to supply a gas water heater is lost in the form of:

  • Standby losses (-31%)
  • Combustion losses (-17%)
  • Distribution losses (-9%)

With an electric water heater, you don't need to worry about losing half of your power to losses. The Energy Factor (EF) for electric water heaters with a tank size of 50 gallons is 95%, which means only 5% of the device's energy is wasted or lost during the heating process.

Regarding size, a 50 gallon electric water heater has plenty of capacity for large families. If you opt for a smaller unit, such as a 30 gallon heater, you might run out of hot water if your family consumes a lot of water during peak periods.

Typically, 50 gallon water heater tanks are sufficient for families of up to five people. As a general rule, you can assume that for each member of the family you should have 10 gallons. In other words, if you have 4 members in your family, a 40 gallon tank should meet your needs.

Is a 50 Gallon Tank Right for You?

As we discussed above, a 50 gallon tank is an excellent option for families of 4 or 5 people. For every person in the household, you can estimate that about 10 gallons are needed to meet the daily water consumption needs.

Although tankless water heater units provide the most efficient supply of hot water, they must be properly sized for your household to prevent running short of hot water on a regular basis. Plus, they are typically much more expensive than conventional tank-based water heaters.

Many families opt for a 50 gallon electric tank to combine the benefits of having hot water on demand with an energy efficient low-cost solution.

However, you should be aware of size constraints in your home before you invest in a 50 gallon water heater to ensure that it will properly fit. 50 gallon electric water heaters tend to be between 50 and 60 inches high and over 150 pounds. Always make sure your home has ample space to store and house a tank of this size.

Electric vs Gas Water Heaters: Which is Better?

Electric and gas water heaters both have their share of advantages and disadvantages. Below, you'll find some of the key differences between these two types of water heating systems, as well as where each has an edge over the other.

Electric Water Heaters

There's a lot to like about electric water heaters. Perhaps the main benefit of this type of water heater is that they have low upfront costs, as they are often several hundred dollars less expensive than gas-powered heaters. They're also safe to operate and have extremely high EF (energy efficiency) ratings.

Due to their energy efficient properties, electric water heaters are more environmentally friendly. Switching to an electric water heater reduces the amount of power consumption required to supply a family with hot water which, in turn, reduces your carbon footprint.

But keep in mind, that even though your electric heater is more energy efficient, it will cost more to operate. This is because electricity is more expensive than natural gas.

The downside, is that if the power grid goes down your water heater will too. Although, this typically isn't an issue unless you have an extended power outage.

Another shortcoming is they have longer heating rates and recovery times. This means it takes longer to heat the water and for your heater to recover back to a full hot tank. 


  • Low upfront costs
  • Safer to operate and maintain
  • Highly energy efficient
  • No ventilation system required


  • Slower heating and recover times
  • Vulnerable to power outages and blackouts
  • Higher operating costs

Gas Water Heaters

Gas water heaters use British Thermal Units (BTU) to rate their heating power, where electric water heaters are measured in watts. Modern gas water heaters have BTU measurements as high a 180,000 BTUs, which can heat a 50 gallon tank faster than even the most efficient electric water heaters.

As a general rule, you can expect a gas heater to convert heat much faster than an electric water heater, making them a popular choice for households with high hot water needs.

The downside to gas water heaters is that they have higher upfront installation and unit costs. They require a purpose-built ventilation system to vent the exhaust created from combustion to outside the home. If there's ever an issue with the ventilation or a gas leak, a gas water heater can present a danger to the home and occupants.

Another drawback is that not all areas have natural gas available. 


  • Fast water heating capabilities
  • Lower operating costs
  • Rapid recovery rates


  • Higher upfront costs
  • Less energy efficient than electric water heater systems
  • Must be ventilated

Other Considerations

When shopping for a new electric water heater there are several factors that you should consider before making a buying decision. Here are a few key factors to consider to help guide you towards making an informed purchase.

Space Requirements - Be mindful of the space your household has to accommodate a large water heater. If you have low ceilings, for example, you may need to opt for a "lowboy" or short framed water heater.

Warranty - No water heater lasts forever. Before purchasing a new water heater system, research the manufacturer's warranty to check the coverage. In some cases, heaters can be covered under warranty for as many as 12 years.

Drain Valves - Every water heater has a drain valve at the bottom to drain the tank for repairs and maintenance. Some units come with drain valves that are made of brass or metal alloy, but if yours is made of plastic you may want to consider changing it out with a brass one before filling your tank. Plastic drain valves tend to leak after a few years of use.

Solar Compatibility - Many modern electric water heaters can accommodate photovoltaic (PV) panels to power the heater via solar energy. If you want to minimize your carbon footprint and lower your energy bill, a solar-compatible heater may be a worthwhile investment.
