How many watts are used in a hot water heater?
A typical home hot water heater uses 4800 watts. The circuitry connecting to the tanks is a 20 amp breaker with #12 wire for the connection. The tank draws 20 amps. W = A x V = 20 x 240 = 4800 watts. Some industrial hot water tanks can be rated at four times the size of home tanks.
Should a hot water heater be put on a 30 single or 30 double amp breaker?
What governs the type of breaker is the voltage and wattage of the heater elements. If the tank is 120V then you would only use one breaker. The size of the breaker you use will depend on the watts of the element. Watts = amps x volts, Amps = Watts/ volts. Once you establish the amperage then size the wire and the breaker to fit. If the tank is 240V the same rules apply only you would use a 2 pole breaker. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicatorto insure the circuit is, in fact, de-energized.
