An 80-gallon electric water heater is a popular choice among homeowners and businesses alike. This type of water heater is known for its efficiency, reliability, and capacity to provide a steady supply of hot water for various needs.

Why Choose an 80 Gallon Electric Water Heater?

Capacity: An 80-gallon water heater is ideal for medium to large households, or businesses that require a substantial amount of hot water. It can comfortably serve a family of four to six people, ensuring everyone gets their hot shower in the morning.

  • Energy Efficiency: Compared to gas water heaters, electric water heaters typically use less energy. They produce heat from practically all of the electricity they need, so there is less energy lost.
  • Ease of Installation: Unlike gas water heaters, electric models don’t require a flue for venting. This makes them easier and cheaper to install, as they can be placed in more locations within a property.

Key Features to Look For

When shopping for an 80-gallon electric water heater, consider the following features:

  • Energy Factor (EF): This gauges how well the device produces heat from electricity. The water heater is more efficient the higher the EF.
  • First Hour Rating (FHR): This tells you how much hot water the heater can supply in the first hour of operation. Make sure the FHR meets your household’s peak hour demand.
  • Warranty: Look for units with a long warranty period. This is a positive sign of the manufacturer’s faith in their offering.

Is an 80-gallon capacity electric water heater enough?

For most households, an 80-gallon heater is more than enough. Eighty gallons should be plenty if you have a large bathtub or performance shower and a family of more than five people.

How long does it take an electric 80-gallon water heater to heat up?

The time it takes for an 80-gallon electric water heater to heat up will depend on several factors, including the initial water temperature and the heater’s wattage. However, most models can heat a full tank in about 1-2 hours.

How much does an 80-gallon electric water heater cost?

80-gallon water heaters cost $1,100 to $7,000.


An 80-gallon electric water heater is a great investment for those who need a reliable and efficient source of hot water. By considering the capacity, energy efficiency, and key features, you can find a model that perfectly suits your needs.

Remember, while the initial cost may be higher than smaller units, the convenience and efficiency of an 80-gallon electric water heater can provide significant savings in the long run.
