Electric Water Heater Thermostat Wiring

A wiring diagram is a simplified standard pictorial representation of an electrical circuit.

Electric water heater thermostat wiring.

Meaning that only one element is allowed to heat at a time. These thermostat we used for controlling the water heater element. Black color is neutral while red is phase or line and the yellow green wire is used for ground earth. Wiring an electric water heater also includes the thermostats.

We use water heater thermostat for controlling the water temperature. At the water heater the black circuit wire connects to the black wire. Usually when the upper thermostat goes bad you will have no hot water at all while a bad lower thermostat makes itself known when there is only a small amount of hot water before the tap water goes cold. The circuit wiring typically includes a 30 amp double pole breaker and 10 2 non metallic nm or mc cable.

The line is connected to the l 1 terminal while neutral or second line is connected to the l 3 terminal. These are usually set up for non simultaneous operation. Working of a thermostat. An electric hot water heater has two thermostats controlling two separate heating elements one in the upper half of the tank one in the lower half.

Unlike the low voltage thermostats that control central heating and air conditioning systems electric baseboard heaters use line voltage thermostats that are installed as part of the full voltage circuit powering the heater. Most residential water heaters have an upper and a lower thermostat. It shows the elements of the circuit as simplified forms and also the power as well as signal connections between the tools. The wiring connection for both single phase 120v and 240v are same i e.

Electric water heaters require a 240 volt dedicated circuit which serves only the water heater and no other appliances or devices. Understanding water heater wiring. Electric water heater wiring with diagrams explanation. Wiring diagrams residential electric water heaters current production 315267 000 time clock switch operates bottom element only to power supply to time clock switch off peak meter operates.

In general there are three main components in an electric water heater. One is the heating element second is the power switch to avoid overheating problem and the last one is the thermostat. The thermostat can be mounted directly on the heater itself or it can be mounted on the wall so that the circuit wiring passes through the thermostat first on the way to. The water heater element is connected to the thermostat via t 2 as hot and l 4 as neutral.

In this post i am gonna to share with some diagrams which clear your concept about the wiring of water heater geyser.
