30 Gallon Electric Water Heater Recovery Time?

How long should it take an electric water heater (30 gallon) to recover after all of the hot water is used? Also, how many showers, or minutes of shower time, should 30 gallons be good for? Thanks.

    hi 30 gallons convert to liters is 30x4which is 120 liters that’s Lot of water .it takes a kettle three minutes for one liter so i would say 120×3 =360 so for boiling hot water 36 min plus time to fill tank depends on water pressure.

    A 30 gallon is very small for an electric water heater and what you need to realize is that as you use it cold water is entering the tank and mixing with the hot that is already there. If your cold water is very cold it will cool the hot water in the tank very quickly. I am surprised that you even get one good shower from a 30 gallon electric. If you are replacing the tank go with a 50 gallon minimum.
