As long as the hot water tank is no more than fifty feet from the panel, you will need 10/3 with ground wire, wire staples and a 30 amp double pole breaker. Be sure to purchase enough wire with about 4 feet extra to allow for connections.
Be sure to fill the water tank before turning on the power. To be sure it is full, run water through the nearby faucets, turning on the hot water faucets or both to be safe. If you fire up an empty hot water tank you will destroy the heating elements almost instantly.
