Is this an electric heater? If it is, it's a safe bet that you have a 220 volt single phase heater, and probably the reason why you have the red wire. I wouldn't turn on the breaker until you find-out how your heater is fired. If your heater is electric the red wire does NOT go to ground.

Before you turn on any breakers make sure that the wires with the white and black are rated for 30 amps and the covering may be orange or if a few years oldr white and are stamped or lettered 10-2. 10-2. It doesnt matter with the water heaters if you hooked the white to black or red to white, both of these wires should be 110 on each sideThis is a 30amp 220 volt appliance Make sure that the breaker is rated for 30 amps and is a double pole breaker. The bare copper or green shoud be connected to the ground screw inside. Its all filled and ready to go if every thing is checked out and are the same for this answer

Kind of looks like to me that you purchased a 220 hot water heater. Make sure the breaker for the hot water heater is a double pole 220. Older houses were wired as a white being hot, a good electrician will tape that white wire with black tape. If you 110 breaker your heater will work but it will take forever to heat water.

residences contained in the U. S. are normally stressed out one hundred twenty/240 volts (nominal). one hundred twenty volts is used for all the lights and receptacles, yet 240 volts is used for top capacity gadgets like an electric powered selection, an electric powered clothing dryer, critical aircon, and confident, an electric powered water heater. The 240 volts is won via connecting between line to line, while one hundred twenty volts is between line and impartial. the colour code used is white for impartial and black for the line (warm cord). that is why you will come across a white and a black cord related to the wall shops. once you have a line to line connection for 240 volts, between the wires may well be coloration-coded crimson to distinguish it from the different line that's black. that is optionally available, for yet another coloration could desire to be used (different than white or eco-friendly that are consistently impartial and earth floor), or the two wires could desire to be black. now and back the electrician will wrap the tip of a cord with coloured tape as a exchange of utilising a coloured cord. that is for convenience, and may well be carried out at the two ends of the cord. the colour of the tape consistently takes priority over the colour of the cord. the actuality that your water heater has a black and a crimson cord leads me to think of it demands 240 volts enter. yet whilst your electric powered resource has black and white wires, it may desire to purely be one hundred twenty volts. in case you connect a 240 volt water heater to a one hundred twenty volt resource, the water heater will purely produce one million/4 of the rated capacity in watts. that is because of fact capacity is in share to the sq. of the voltage. yet do not undertaking approximately burning up the water heater. won't ensue. won't get warm adequate, till you permit the tank run dry. although, it quite is obtainable that the water heater could draw greater contemporary than what the branch circuit is rated for. subsequently, the circuit breaker will trip, yet back there is not any injury carried out. in the journey that your electric powered resource is 240 volts around the black and white wires, it does not make somewhat distinction the way you hook up the water heater. you may bypass black to black, black to white, crimson to black, or crimson to white. merely merely be valuable you have a floor connection.

It should be correct, but use your multimeter to make sure. (Never assume someone else did the job correctly!)
