Proper installation and maintenance of your water heater can extend its life span. A hot water heater is a vital appliance for your home, as it provides the hot water necessary for bathing, cleaning and washing clothes. As water heaters age, they become less energy efficient and the tanks inside them corrode. This corrosion can cause leaks, and in some cases, cause the tank to burst, flooding your home. Installing a new water heater in time can prevent this from happening. The installation process for an electric hot water heater involves basic plumbing and electric skills. Test the wiring for the water heater by touching the probes of a voltage tester against the bare tips of the wires.

Same is true for water heater elements. Lower wattage heats less water per hour See chart Assumes watt element rated for V Element wattage and voltage printed on end of each element Resource: How to identify and replace elements Formula for toV:.

Voltage higher than element rating: Good for off-peak or generator. How to replace element Connect water heater to generator. Also use Volt strategy when main box is overtaxed If main breaker is tripping.

Main breaker stress test If water heater breaker is getting hot and tripping. Another strategy is to change elelments from watt to watt for slower heating and less draw off breaker Generator may not provide enough wattage for entire house: How to wire volt water heater for volt generator. Toggle water heater between Volt and Volt Max watt non-simultaneous water heater Use Volt during times when electric prices are lower, and faster recovery is needed.

Use Volt during peak prices when less hot water is used Bring Volt from nearby outlet that has 12 gauge wire, or install lower watt elements if wire is only 14 gauge. Using 30 amp Double Pole Double Throw switch Ordinary 3-way switch will do same job, but without center off Also called: Black connects to Volt circuit breaker and White connects to neutral busbar.

How to wire T timer All Intermatic timers Buy: T timer Wires inside water heater do not change.

Elements and thermostats will work with Volt or Volt Element watt consumption drops when voltage drops No need to change breaker. Just run additional neutral wire to timer. How to wire safety switch You can use fusable or non-fusable Having more than one fuse on same line is ok by code. Timers can be wired to toggle water heater between V and V. Mechanical Intermatic GM40 series. Water heater recovers slowly with Volt. Use Volt when electric prices are lower, and faster recovery is needed.

Timers can be wired to toggle water heater between temperatures. Also this wiring technique can be used for off-peak operation.

During peak pricing, only the upper element is working, so amount of available hot water is reduced, and upper element heats more slowly, using fewer Kw per hour of operation. During non-peak pricing, lower element is working, and tank resumes heating as expected. See larger Water heater thermostats at Amazon.

Do it yourself water heater. Motorized shut off valve. This circuit should have been turned off before you removed the old water heater, but double-checking the volt line that powers the water heater can save your life. Move the water heater into position with a hand truck. Have an assistant help you move the water heater if you're struggling to do it yourself.

Place a level on top of the water heater. Place shims under the water heater to level it out, if needed. Wrap Teflon tape tightly around the threads on the pipes that stick out on top of the water heater the cold water inlet pipe and the hot water outlet pipe. The Teflon tape helps provide a tight seal and prevents leaks from occurring.

Connect the water heater to the pipes that carry cold water into the tank and hot water out of the tank, using the provided PEX tubing. Use the red PEX tubing to connect the hot water outlet pipe on top of the water heater to the line that carries hot water to the faucets in your home, and the blue PEX tubing to connect the cold water inlet pipe on top of the water heater to the line that carries water into the water heater.

Close the drain valve at the bottom of the water heater if it's open.

Open all of the hot water taps in your home. Open the valve on the main line that feeds cold water into the water heater.

Allow the water to fill the tank, then flow out through the hot water line and through the spigots in your home. Allow the water to flow through the spigots for about a minute to bleed air that's trapped inside the lines, and turn off the taps.

Remove the metal plate on top of the water heater that conceals the wiring. Pull out the wires that are in the tank. Strip a half-inch of insulation off of the wires with wire strippers.

Punch out the knockout hole next to the wires by tapping on it with a hammer and screwdriver. Connect a cable connector to the knockout hole with a wire nut. The cable connector covers the knockout hole and has a screw on the side that locks the electrical cable in place, preventing it from sliding around, which can damage the insulation.

Insert the cable that runs to the main electrical panel through an electrical conduit. Slide the end of the cable through the cable connector and into the top of the water heater until the wires from the cable can be connected to the wires inside the water heater.

Insert the end of the conduit into the cable connector and tighten the screw on the cable connector.

Twist the red wire from the water heater to the red wire from the electrical cable with a pair of pliers. Place a plastic twist cap onto the wires and twist it several times.
