Bradford White Electric Water Heater Wiring Diagram – The thermostat must sit flush against the tank wall to read the correct temperature. Variable thermostat. Check that the bracket is not corroded or loose.
Both elements are never “on” at the same time, unless the tank is wired for other purposes (see owner’s manual). Since both items are not “on” at the same time, this is called a “non-concurrent operation”.

Goal: Add an extra tank to increase hot water availability at peak times without adding an extra 30 amp switch.

When heater #2 is energized, heater #1 does not heat. But if heater #1 needs to start heating again, heater #2 will turn off.
: Adding extra wire to heater #1 may require a long drill bit to bring the wire to the top of the tank. Be sure to insulate and cover the thermostats to prevent them from being exposed to low temperatures and causing erroneous temperature readings.
240 volts has 2 voltage wires. Boiler thermostats only turn off 1 of the 2 hot wires going to the elements.
This means each element has 1 hot wire that goes ON-OFF, and the other hot wire always has power… and so the elements will always test 120 volts to ground.

If the water heater has foam insulation, it may not be easy to replace the lower thermostat with an ECO-protected thermostat.
Remove the top thermostat and fabricate a new bottom thermostat that will work for the specific two boiler diagrams above.
ECO starts at 170°F and protects you and the tank in the event of overheating and is required for safe heater operation. Conventional residential steel water heaters are rated for 150°F, but are designed to resist breakage up to 300°F, assuming the tank doesn’t rust. The TP valve releases water at 210°F, the highest temperature allowed for any type of water heater, to protect against a violent steam explosion that would completely destroy the house.
Single element thermostat Same thermostat is used for both 120V and 240V / See label on side of tank for correct water heater voltage

Thermostats without the T4 screw or the 3rd screw on the right are designed for a single element tank only.
1. The bottom thermostat has been replaced with an ECO protected thermostat which is the same as the top thermostat. The ECO safety reset in red cuts power when the water in the tank reaches a dangerously high 170°F
2. Upper Thermostat: The red wire has been moved from L4 to T4 so that the lower thermostat and element can only be energized when the top of the tank is heated. The color of the wires is different.
4. A black wire from L1 on the lower thermostat runs to the top of the water heater where the output is connected to a peak meter or off peak timer.

5. At the top of the tank, Black L1 and Yellow L1 come from the same leg on the 240V switch and Black Hot 2 come from the other leg on the 240V switch. Look at the picture
Records billable energy consumption in Kwh. Multiply the rate you pay per Kwh to get the monthly/annual cost of an electric water heater.
Boiler companies connect their products to the future smart grid. In addition, they install electronic thermostats. Consider whole-house surge protection
As companies try to increase sales by using custom parts that must be ordered from them, the cycle of generic off-the-shelf parts is quickly coming to an end.

This diagram does not require you to size up the wire or circuit breaker. Use a timer for two different temperatures on an electric water heater.
Either the top thermostat and element have power, or the bottom thermostat and element have power. But not both at the same time.
Normal operation, thermostat low and the element is energized and maintains the tank at the set temperature. The top thermostat and element have no power.

This is called a “failed” operation of the water heater. This method of heating the tank faster after the cold water first enters the tank.
When you start the timer, the power to the bottom of the tank is OFF. Power starts at the top of the tank. The top thermostat is set to a higher temperature.
Since the tank is at normal temperature, a higher setting means that the top element kicks in and begins to heat the tank to a higher set point.
Downside: Once the new cold water enters the tank, the bottom of the tank cools down quickly, so this technique is good for making short-term hot water batches.

The ECO proof thermostat should be kept at the top of the tank to avoid overheating which can damage or break the tank, cause boiling, release hot water through the TP valve and distillation of chemicals from the water.
Heater #2 may not have fully warmed up before heater #1 restarts. This happens if the boiler is poorly insulated or if hot water is drawn from boiler #1 or if the incoming water is too cold.
2) ECO protection may be required if heat rises at the top of the tank to prevent overheating
3) The conventional lower thermostat of heater #1 has been replaced with an ECO thermostat, so that power can be transferred to heater #2 when the thermostats of heater #1 are fitted.

Essentially an ECO protected thermostat is added to the bottom of heater #1 and a wire is added from the bottom thermostat so that power can be transferred to heater #2.
Foam insulated water heaters may require long drill bits or home center roasting tips to bring the wire to the top of the tank. Make sure that insulation and covers are placed over the thermostats so that the thermostat is not exposed to cold temperatures and can cause erroneous temperature readings.
Charge the water heaters in series and run an additional 30 amp circuit to the booster heater. Then put both boilers on timer
Identify an unbalanced water heater: It looks like a normal tank heater and does not have a large metal box with switches on the front of the unit.

Unbalanced means that 1 leg of three phases carries more load than the other two legs. So this is a regular single phase water heater apart from a few wires so there is a 3 wire connection on top of the unit. The difference is that an unbalanced 3 phase usually has larger wires, breakers and elements.
An unbalanced water heater uses a conventional 2-prong element and thermostat, except the thermostat is rated for 40 amps at 240 volts and 30 amps at 480 volts.
Compare with non-simultaneous above: move the red wire from T4 on the top thermostat to L1 on the top thermostat
