Before buying the new water heater, check the electrical load it requires. In many cases, keeping the same size tank prevents the need to upgrade the circuit. Upgrading to an on-demand water heater or larger tank is likely to require a circuit breaker upgrade.
The capacity of the electric panel is on the main breaker. The total of the breakers in the panel should not add up to more than the main breaker. If adding the upgraded water heater circuit breaker exceeds this maximum, upgrade the electric panel to meet the new demand.
Many building codes require the purchase of an electrical permit before making changes to the electric panel. Purchase the permit before beginning any work.
Purchase a new electrical breaker designed to fit your electrical panel. Turn off the main breaker. Remove the faceplate from the panel. Pull on one end of the breaker to remove it from the panel. Remove the wires from the circuit breaker. Reverse the steps to install the new breaker.
If the existing wiring is not sufficient to carry the load, upgrade it to meet the electrical code.
