Installing an Electric Water Heater

 
 

Even with proper maintenance, your electric water heater will eventually need to be replaced. Today's water heaters are designed to last 6 to 12 years.

 

Step one of this project begins after the old water heater has been removed. When working on an electric water heater installation, the first step is to turn off the power. Do not restore power until the job is done. Also make sure the heater is full of water before you restore power; otherwise you will destroy the heating element.


 

WHAT YOU NEED FOR THIS JOB:

TOOLS:

MATERIALS:


 

Step 1 

Step 1: Set the water heater in place

Set The Water Heater In Place

 

Use a carpenter's level along the side of the water heater to level it with wooden
or plastic shims.

  

Step 2 

Step 2: Sweat Solder the Shutoff Valve to the End of the Cold Water Supply Pipe

or Coat with Pipe Compound

 

1. Attach the blue-coded fitting to the cold water inlet and the red-coded fitting to the 
    hot-water outlet. These fittings are directional; they have arrows that show the 
    proper installation
 
2.Tighten with an adjustable wrench.

Step 4: Install the Water Supply and Fill Tank

Install the Water Supply and Fill Tank

 

1.  Connect the plumbing supply lines to the water heater according to the 
     manufacturer's instructions and local code requirements. Solid copper 
     pipe or flexible copper supply lines are the most common options.  
 
2.  Make sure drain valve is completely closed.  
 
3.  Turn the main water supply on and open all line valves.  
 
4.  Open one or more faucets on the home's highest floor and run the water until it 
      flows steadily from the faucets. A steady flow of water from the hot water 
      faucet(s) indicates a full water heater.  
 
5.  When completely filled, close the faucet(s) and check for leaks.

1.  Before you do any electrical work, ensure that power to the water heater is turned 
     off at the main circuit breaker; if you have fuses, remove them.  
 
2.  Connect the electrical supply according to the manufacturer's instructions using 
     wire nuts.  
 
3.  Connect the bare copper or ground wire to the ground screw. Replace the 
     electrical access plate.

Step 6: Adjust the Thermostat

Adjust the Thermostat

 

1.  Remove the thermostat access plate (most likely on the side of the unit).  
 
2.  Pull back any insulation to expose the thermostat.  
 
3.  Use a screwdriver to change the thermostat temperature in 10-degree increments.
     Recommended settings are 120 to 125 degrees.  
 
4.  Replace thermostat access plate.  
 
5.  When the tank is full, restore power and press the reset button on the panel.
