Electric water heaters are available in gallon capacity sizes for 2.5 gallons up to 120 gallons. They are very versatile and can be installed in almost any location as long as there is a water supply and the correct electrical supply. Residential electric water heaters generally range from 30 gallons to 52 gallons. For large homes or when solar systems are present capacities range from 66 to120 gallons. Residential electric tanks typically have a 240 volt electrical connection.
In commercial businesses such a gas stations and office buildings we often see smaller point of use units in 2.5, 5, 10, and 20 gallon capacities installed. This type of water heater provides a small amount of hot water and can be installed directly at the fixture. These water heaters come prewired with a 120 volt connection and can be hardwired or plugged in depending on the application.
Larger and more powerful commercial electric water heaters range from 2.5 to 175 gallons. They also come with a wide range of electrical options. Tanks can be wired from 3kw (kilowatt) to 90kw depending on the need. They are also available with 120 volt, 208 volt, 240 volt or 480 volt wiring. These water heaters are designed to provide high volumes of hot water.
If you are replacing a commercial electric water heater, we always recommend you get the specs directly from the existing water heater if possible, including model number, serial number, kilowatt hours, and voltage. This way you can match the old specs with the new heater. It is important to find a model with the exact specs for safety purposes when doing a replacement installation.
