    The circuit for my water heater is a dedicated circuit, I just need to be able to easily move it several times as I work in the laundry room, so I would like to be able to plug it in using the dryer cord as opposed to having it hard wired as it is now.

  2. Dave Rongey says:

    Hi Shirley,
    An electric dryer and electric water heater require dedicated circuits due to the amount of electrical power that is required by each separate unit. If the water heater were to be connected to the electric dryer circuit the circuit breaker would eventually trip off because the circuit would become overloaded when both units were running and consuming power at the same time. Therefore for our convenience and safety the electrical code requires that a separate circuit is installed for an electric water heater.
    Be Safe,

    I live in Texas and would like to put my 40 gallon water heater in with a 30amp plug and receptacle normally used on a electric clothes dryer, can I do this? Don’t know if it’s allowed.
