How To Install Electric Water Heater

How to Install an Electric Water Heater

Installing a new electric water heater can allow you to save both money and electricity. How to do it is demonstrated in our video and step-by-step instructions. Please keep in mind that product pricing, availability, and item numbers may differ from market to market.

Before You Begin

Examine your water heater to see whether it need replacement or if routine maintenance would suffice. There might be a problem with the heating element or another type of maintenance issue if you are not getting hot water. Before committing to a complete replacement, conduct a brief maintenance inspection. If you have water on the floor or on top of the unit (as opposed to water leaking from a supply line above the unit), you’ll most likely need to replace your water heater as soon as possible.

A excellent time to think about upgrading or reducing your electric water heater is when your family’s size has increased or decreased.

If you’re not confident in your ability to complete water heater installation, hire a professional.

A decrease in pressure reduces the stress placed on plumbing systems and helps to increase the lifespan of appliances and fixtures.

Water Pressure

The water pressure in your house is critical for all of the equipment that use water. A decrease in pressure reduces the stress placed on plumbing systems and helps to increase the lifespan of appliances and fixtures. Check the water pressure in your house by attaching a pressure gauge to an exterior spigot. The optimal PSI ranges from 50 to 60 PSI. if the water pressure in your house is more than 80 PSI, use the pressure-reducing valve located near the main water shut-off to decrease the pressure.

If you don’t already have a pressure-reducing valve in your house, a professional can install one for you.

Expansion Tank

Decide the type of expansion tank you’ll require. It is possible to reduce surplus pressure in the lines of a closed system using thermal expansion tanks. A 2-gallon expansion tank can be used with water heaters that hold up to 50 gallons of water. For water heaters that hold up to 100 gallons of water, a 5-gallon expansion tank should be used. For for size information, see the manufacturer’s instructions. In most cases, the expansion tank is connected to the cold-water supply pipe near or above the water heater.

They simply slot into the pipe without the need for soldering.

Soldering paste should be applied to both the pipe and the fittings before assembling.

After heating the fitting, solder the connection together. In order for an electric water heater installation to be functional, the pressure in the expansion tank must equal the pressure in the main water supply. Increase the pressure by using a hand air pump, or decrease it by depressing the valve.

Removing the Old Water Heater

The following steps will walk you through the process of installing an electric water heater. When transporting a water heater, employ a helper, an appliance dolly, or a hand truck to ensure that the device is not damaged.

Preventing Scalds

Even with the temperature gauge set at 120 degrees, the risk of scalds remains a possibility. Children, the elderly, and individuals with delicate skin are particularly at risk of developing skin cancer. Consider adding thermostatic mixing valves to keep people safe from being hurt. Installed at the point of use faucet, fixture, or appliance, a thermostatic mixing valve regulates both the volume and temperature of water by connecting to both the hot and cold water supply lines at the same location.

Electric Water Heater Installation: Step-by-Step Guide

If you’re the DIY kind, installing an electric water heater isn’t quite as complicated as it may appear at first glance. However, before starting the project, you should keep in mind that you will be required to perform some basic plumbing and electrical tasks. Even if these kind of jobs make you feel uncomfortable, there are several trustworthy companies that you may hire to install your new water heater. Nevertheless, if you’re up to the task, you may save money by doing it yourself. Generally speaking, electric water heaters have a life span of 8 to 10 years before they need to be replaced.

If you haven’t previously done so, you should troubleshoot the leak before investing in a new water heater.

Except if you discover that the leak is coming from the tank itself, you will have no choice but to replace the water heater.

Furthermore, if you elect to install the water heater yourself, you will be responsible for removing your old water heater and properly disposing of it. Find Local Plumbing Professionals

Tools and Supplies

Installing an electric water heater is far less difficult than installing a gas water heater, but it is still a significant undertaking. Our recommendation is to hire a professional to complete the installation if you are unfamiliar with electrical and plumbing. In addition, they will often dispose of your old water heater for you as part of the installation process. The following are step-by-step instructions for installing your electric water heater:

Disconnect the Electricity

First, we’ll have a look at what to do. Turn off the electricity to your water heater at the circuit breaker panel located near your water heater. Check the wiring of the water heater using a voltage tester to ensure that the device is turned off. Although it is not discussed in the video below, it is always a good idea to double-check that the water heater is not receiving any power after turning it off at the circuit breaker before doing any work on it. Start by turning on a hot water faucet and letting the water flow until it is cold.

The cold water feed to the water heater should be turned off (located at the top of the unit).

Drain the tank by opening the valve and venting it to the outside (or to a floor drain, or even into buckets).

The hot water faucet should be reopened if it was closed in Step 1, as described above. You may also use the T P valve to your advantage. By enabling air to enter the tank, you will be able to drain the water more quickly.

Disconnect the Electrical

The next step is to disconnect the electrical cables from the water heater’s top. To begin, be certain that the circuit breaker in the breaker box has been switched off. Then, before you begin, verify the wires with a voltage tester to ensure they are in good working order. Cap the wires and name them (or take a picture of them) so that there is no confusion when you are connecting your new water heater in the future.

Disconnect the Plumbing

Step 4Disconnect the hot and cold water supply lines from the water heater. Copper plumbing may have been used in the installation of your water heater, and you may need to cut the pipes. If you need to cut the pipes, use a tubing (pipe) cutter and try to leave as much of the pipe as feasible intact as you can before cutting. If the discharge pipe from the T P valve is in good condition, you can remove it from the T P valve and reuse it on your new water heater.

Remove the Old Water Heater

Step 5: Using a dolly, move the old water heater out of the way after the tank is empty. Place the new tank in its proper location. It is recommended that the replacement tank be placed in a drain pan. Find out why. Make certain that your electrical supply will be sufficient to reach the tank. Check sure you have access to the panels and the drain valve in case you need to do maintenance.

Prepare the Plumbing Lines

The pipes will need to be prepared with a sandpaper cloth if your old water heater had copper plumbing and it was required to cut the pipes. Rub the ends of the pipes with the sandpaper cloth until they are gleaming brilliantly again. Find Local Plumbing Professionals

Connect the Electrical Wiring

In order to gain access to the electrical cables, remove the junction box cover in Step 7. Attach the ground wire to the green ground screw using a crimp connector. Wire connectors are used to join the other wires together by twisting them together. Make use of the prior wire connections as a reference and reconnect the wires in the same manner in which they were disconnected. Follow the directions on your label tags or the photo you took in Step 3. After that, reinstall the lid of the junction box.

Attach the Supply LinesTurn On the Water

Step 8: Connect the water supply lines for hot and cold water. Make certain that the cold water pipe is connected to the cold water intake on the water heater (it’s easy to make the error of connecting the cold to the hot water pipe). If your old water heater was plumbed with copper piping, you may want to consider plumbed it with copper piping once more. Flexible hoses, on the other hand, are highly recommended for making the connections. Not only is it more convenient, but it is also a suggested safety element in the event of an earthquake.

  1. Connect the flexible hoses to the nipples on the water heater using the hose clamps.
  2. When connecting flexible hoses to the hot and cold water pipes, we recommend that you use dielectric connections to prevent shock.
  3. By turning on the hot water faucet at the adjacent faucet, you may check for leaks in the flexible hose connections.
  4. Although this step is not discussed in the video, we recommend that you double-check your plumbing before continuing forward with the project.

As long as there are no leaks, you may keep filling your water heater tank with water. As soon as the tank is completely refilled, water will begin to flow out of the hot water faucet.

Attach the T P Discharge Pipe

Step 9Connect the discharge line to the T P valve and tighten it. The pipe’s end must be within 6 inches of the floor in order to function properly.

  • Make use of a 3/4-inch male copper fitting. Paintpipe dope applied on the exterior of the fitting as well as the interior of the valve fittings. Tighten the fitting to the T P valve fitting once it has been attached. Remove the fitting from the pipe’s end and clean it
  • Soldering flux should be painted on the inside of the male fitting and outside of the pipe. Fitting the pipe to the fitting is completed. To join the pipes, solder and a torch should be used.

Turn On the PowerBleed the Hot Water Lines

Step 10After your water heater tank has been completely filled with water, switch on the circuit breaker located at the main power panel. Attention must be taken when turning on the electricity before the tank has entirely filled since the electric components may dry up if they are not totally immersed. This might cause irreparable damage to your electric heating components. Remember to switch off the circuit breaker before inspecting the electrical connections on your water heater if your water heater isn’t getting electricity.

Bleed Hot Water Lines

Step 11Allow the hot water tap to run for a few minutes until it stops “sputtering” in order to expel the air trapped in the tank and piping system. It may take many hours for the water in the tank to reach its maximum temperature. The temperature setting that is recommended is 120 degrees Fahrenheit. Let it sit for a couple of hours before checking the T P discharge pipe. If the pipe is dripping, it is possible that the pressure is too high.

How To Install An Electric Water Heater

A water heater, particularly an electric kind, is a very basic piece of equipment. Unheated water enters the tank by one of its sides. Several electric resistance components that stretch from the edge of the tank into the middle of the water are responsible for heating the water in the tank. The water then leaves from the other side of the tank when the demand is there. Unfortunately, this ease of use does not extend to the process of installing the software. While not difficult, installing an electric water heater does include some plumbing and electrical work, which may be enough to deter some homeowners from taking on the project.

  1. Compared to other frequent home pastimes like refinishing furniture or managing a productive vegetable or flower garden, the skills necessary for this task are not nearly as difficult.
  2. This is an excellent method of reducing the number of fittings you require as well as the number of journeys to the hardware shop to get the items you have forgotten.
  3. If all you’re doing is replacing a tank in the same location, you’ll have even less work on your hands.
  4. Keep in mind to integrate any particular manufacturer instructions into your preparations, especially if failing to do so may result in the product warranty being voided.

Step 1: Build a Platform

Choose a handy location for the tank and install two or three concrete blocks on the floor to act as a foundation.

Using these blocks, you may assist avoid damage from minor floods while also making access to the drain much simpler.

Step 2: Center the Tank

After that, slide the tank on top of the blocks, being care to keep the drain faucet toward the front of the tank. Using your hands, gently rock the tank back and forth to ensure that the blocks do not move. Reposition everything until the tank is steady if the blocks begin to shift or the tank begins to rock on top of the blocks.

Step 3: Soldering Basics

Soldering copper tubing and fittings is one of the most straightforward skills to learn in the construction industry. To complete this project, you’ll need only a propane or Mapp gas torch (we recommend the Mapp gas torch because it burns hotter and melts lead-free solder more effectively), a tubing cutter, several pads of steel wool and a wire brush to clean the ends of the fittings. You’ll also need some lead-free solder, which you can buy at any hardware store. All of these goods can be found at most local hardware stores and home improvement centers on a regular basis.

  • To begin, cut a 6- to 8-inch-long piece of 3/4-inch-diameter tubing for the cold water entrance line on the tank, depending on how long you want it to be.
  • Following that, use a piece of steel wool to clean the end of the tube.
  • Then, using some soldering flux, cover the cleaned area and set the item away for a while.
  • All you have to do is put the brush into the fitting’s end and twirl it till the surface is clean.
  • To begin heating the joint, switch on the torch and adjust the flame so that the inner blue flame is approximately 3/4 of an inch long on the inside.
  • You don’t have to move the flame around the joint to get this result.
  • As soon as the flux has disappeared, apply a little amount of solder to the top of the junction.
See also:  What Setting Should My Hot Water Heater Be On?

If this is the case, simply pull off the solder, keep the junction heated, and try again.

This indicates that the joint is completely filled.

Make careful you use thick gloves to avoid getting burned.

Clean all of the tube ends and fittings as you did previously, add some flux, and solder the pieces together to complete the installation.

Insert the tape in the tape dispenser in a clockwise orientation.

Then, using a nut, secure the two pieces of the union together securely in their respective positions.

After that, clean and flux a shutdown valve for the cold side of the system, slip it over the tubing end, and solder it in place to complete the installation. For this application, we utilized a ball valve, but a gate valve with sweat fittings on both ends might easily be used instead.

Step 4: T P Valve

Temperature and pressure relief valves (also known as T P valves) serve as a safety measure by creating a channel for water to escape from a storage tank when the pressure inside the tank reaches an unsafe level for any cause. Ensure that the valve you choose is rated at the same capacity as your hot water heater. The product literature for each will provide detailed information on what is necessary. Our solution consisted simply in matching the ANSI (American National Standards Institute) ratings of both products.

  • Take 4 in.
  • As soon as you have completed your measurement, remove the temperature and pressure relief valves.
  • Replace the valve in the tank by tightening it with an adjustable wrench.
  • Cut the relief valve tube to the desired length and solder a male adaptor to one end of the tube to complete the installation.
  • Insert the drain tube into the relief valve and secure it with a wrench.

Step 5: Electrical Power

A separate 220-volt circuit is usually required for a water heater, and in our instance, a 30-amp circuit breaker as well as a 10/2 (with ground) circuit wire were required. These were already in place on our project site, but the cable terminated roughly 20 feet distant from the placement of our new storage tank. Using a joist-mounted junction box, we ran new cable to the new tank site by bored holes through the middle of the overhead joists and extending the wire down the side of the joists where it was handy.

  1. To obtain access to the electrical wiring in your tank, begin by removing the top-most covering plate.
  2. To accomplish this, look for a knockout on the top of the tank and use a screwdriver and hammer to force it down.
  3. Insert the threaded end of a conduit connector into the knockout hole and tighten it in place with the connection nut to secure it in place.
  4. The free end of the cable should be inserted into the pipe’s uppermost section and pulled out the lowermost portion.
  5. Attach the ground wire from the cable to the grounding screw located inside the tank opening and tighten it down with the connection screw to secure it in place.
  6. After that, just replace the covering plate and your installation is complete.
  7. Keep in mind to close the drain valve before turning on the water supply.
  8. If you switch on the elements before the tank is completely filled with water, they will be destroyed and will need to be replaced immediately.

How to Install an Electric Water Heater (10 Steps & Done!)

Almost anyone with rudimentary electrical and plumbing connection abilities can learn how to install an electric water heater — and complete the job — in about a day. Not bad for a profession that many people would find too intimidating to embark on in the first place. Here are the fundamentals of how to install an electric water heater for all of our do-it-yourself readers who enjoy a mild challenge.

How to Install an Electric Water Heater in 10 Steps

The three parts that follow cover all of the fundamentals of replacing and installing an electric water heater in its current location.

What You’ll Need

  • Pipe wrenches, as well as adjustable wrenches (for unions and fittings), are also available. Garden hose (to drain the water)
  • Level (in order to ensure that a horizontal plane is maintained)
  • A screwdriver, a neon circuit tester, and other tools. For moving big water heaters, you’ll need a strong back and an equally strong companion.


In this position, you will be dealing with 240-volt circuits. And that’s a really terrible situation. We highly advise that you remove the fuse or switch off the circuit breaker before beginning. A 240-volt circuit has the capacity to kill you, albeit it is unlikely to do so in most cases. Don’t take any risks with your safety. Make sure your hands are dry and that you are wearing protective gloves and shoes with rubber soles.

Basic Instructions

  1. Turn off the water and electricity. To begin, make sure you turn off the water and electricity to your old electric water heater before proceeding with the rest of the process. Check to see whether there is any electricity. Remove the access panel that allows you to reach the thermostat on your present electric water heater. It’s normally found behind the lower panel of the cabinet. Clear the path by pushing away any insulation that is in your way and lifting (or removing) the protective plastic guard. Using your neon tester, check for the presence of a live current. To be certain that you have shut off the right electrical circuit (see step 1 above), you need double-check your work. Disconnect and label cables as needed. Remove the electrical cover plate, which can be found on the side or on the top of the device. Disconnect the cables and label them with strips of tape so you’ll know precisely where to connect them to the new unit when you get it. Remove the cable clap by loosening the screw on the cable clap and carefully pulling out the cable
  2. Tank should be drained Drain the water pipes in your home by turning on the hot and cold faucets in an upstairs faucet at the same time. Additionally, open the two taps that are nearest to the system’s lowest point. Connect a garden hose to the drain valve on the water heater. Activate the valve and let the tank to empty
  3. Disconnect the water supply lines. Mark the hot- and cold-water lines to ensure that you do not connect the new electric water heater in the wrong direction. If you are using galvanized tubing, make sure the unions are open near the unit. To cut stiff copper pipe immediately below the shutdown valves, use a hacksaw or a pipe cutter to cut the pipe at an angle. If possible, make the incisions straight so that you can simply tap into the lines with new soldered pipe or flexible water lines once the new water heater has been installed. If you have any flexible lines, you should turn them off. With the use of an appliance dolly, remove the old unit. Lifting the unit without a dolly or with a lot of assistance from a strong assistant is not recommended. Install the new device in its proper location. Install the new electric water heater in its proper location. Place it in a convenient location to make your connections as simple as feasible. Make sure everything is plumb and level. If a shim is required, use it. If the device will be located in a moist environment, a tray-like base should be purchased to protect it. Water pipes should be connected. Water lines should be installed. Galvanized steel pipe, rigid copper pipe, and flexible water connections are all options for supply lines. Install a ball valve on the supply line to prevent backflow. After that, install a relief valve and connect it to an outflow pipe. Make the necessary electrical connections. Remove the cover plate from the electrical outlet on the new water heater. Feed the cable through the clamp as far as it will go. Using wire connectors, connect the black and white wires together, and then join the ground wire to the ground screw. Re-install the cover plate and tighten the screw on the clamp to keep the cable in place
  4. Gently push the wires into the clamp and restore the cover plate. Set the thermostat to a comfortable temperature. Set the temperature of your new electric water heater to the desired level. To take a break, use the rest button. Install a new plastic shield and insulation, as well as access panels
  5. Turn on the water. Open the water supply valve if necessary. Allow the system to bleed by opening the nearest hot faucet approximately halfway and turning it off. The first thing that will come out will be air, followed by a spattering of water mixed with air. At long last, once the water is flowing freely, turn off the faucet.

Even if you do not require a new water heater at this time, it is likely that you will require one within the next few years. Water heaters typically have a lifespan of seven to fifteen years. If yours is beginning to show signs of wear, this post is also for you. If you’re familiar with basic equipment and have a little expertise soldering copper, replacing a water heater shouldn’t be too tough.

Tools Required

  • Water and gas piping
  • Discharge pipe
  • Fittings
  • Pipe thread compound
  • Pressure relief valve
  • Solder. Ventilation pipe and connections
  • Pressure relief valve.

Getting Started Installing Your New Hot Water Tank

In this example, we’re swapping out a natural gas water heater for an electric water heater. The processes for replacing a propane water heater are identical to those for replacing an electric water heater, and the steps for replacing both are comparable. In any event, when it comes to arranging a water heater replacement, it’s best to be cautious. Call your local department of inspections and inquire as to whether or not you require a permit. Also, be certain that your work is checked by a plumbing or electrical inspector.

Plumbers normally charge between $45 and $65 per hour and can complete the installation of a water heater in a day or as little as 6-8 hours.

Gas water heaters with particular venting systems are also available, although they are more costly. However, because they are more difficult to install, we will not be covering them in this article.

Water Heater Parts and Breakdown

  • As part of our demonstration, we’re swapping out a natural gas water heater. Replacing a propane water heater is identical to replacing an electric water heater, and the procedures are almost identical. Anyhow, when it comes to replacing your water heater, it’s best to be cautious. To find out if you require a permission, contact your local department of inspections. Additionally, ensure that your work is checked by a plumbing or electrical inspector. Expenses associated with installation and labor Water heater installation is often completed in a day or within 6-8 hours by a plumber charging $45 to $65 per hour. For the most part, a gas or electric water heater will cost between $150 and $400, with an additional $200 to $450 for professional installation. Gas water heaters with specialized venting systems are also available at a higher price point, though. We will not cover them in this article because they are more complicated to install.

When to get a new water heater

When the tank of your water heater leaks, your water heater is out of commission. An indication that your water heater needs to be replaced is a gradual drop beneath the unit, which commonly manifests itself as a trail of discolored water. This indicates that the steel tank has corroded through and will be unable to be repaired. Other symptoms, such as little or no hot water, are typically indicative of other water heater repair issues that may be resolved by you. If you notice a drop, make a plan to get the water heater replaced as soon as possible.

  • New water heaters are sent with detailed installation instructions as well as several cautions to ensure that the gas, electrical, and other connections are handled properly.
  • However, you should be aware that you will be dealing with natural gas, propane, or electricity, all of which are potentially harmful.
  • And, after you’re finished, get your work examined.
  • You should explain to your local plumbing inspector how you want to install your new connections, including the sorts of materials you intend to use.

Mr. Fix-It-Up-For-The-Family See the Additional Information section at the end of this article for instructions on how to print this image.

Figure B: Connections for Steel and Plastic Pipe

Mr. Fix-It-Up-For-The-Family Water supply pipes in many residences are made of galvanized steel or polyvinyl chloride (CPVC). Replaceable galvanized steel pipes are quite difficult to come by. Using our photo series, we propose that you return the pipes to their original tees and screw on a plastic-lined galvanized nipple before finishing the connections with copper. Plastic tubing should be kept at least 6 inches away from the vent and tank due to the possibility of heat accumulation. Using a specific connection, you may make the transition from plastic to copper.

Flexible copper connectors are less difficult to install than solid copper connectors, which is especially important when the existing pipes and tank inlets do not match up.

If yours does, take extra care not to pinch or kink them when handling them.

Project step-by-step (12)

Turn off the gas to the water heater by twisting the shutdown valve a quarter turn away from the water heater. When the handle is turned off, it should be at a straight angle to the pipe. Also, turn off the main water supply and drain the pipes by opening a tap on the lowest floor of the building. Step No. 2

Drain the water in the tank

Connect a garden hose to the drain valve and use it to drain the water that has accumulated in the tank.

The water will be boiling hot, so proceed with caution! With a pair of wrenches, disconnect the gas line at the neighboring union and remove the pipe from the gas control valve with a pipe wrench to complete the task.

Cut off the water lines

The vent pipe should be moved to the side once it has been unscrewed from the vent hood. After that, using a tube cutter, cut the hot and cold water lines. For galvanized pipe, remove the unions and, if you have them, remove the nuts on the flexible connections as well. Move the old water heater to the side of the room. Step number four.

Attach the relief valve

Teflon tape should be used to seal the threads of the new temperature and pressure relief valve (three turns). With a pipe wrench, tighten it inside the tank until it is completely sealed. Glue a copper discharge pipe to the wall (see Fig. A for routing details). Step number five.

Attach pipe assemblies

Solder fresh copper adapters to 6-in. lengths of 3/4-in. copper pipe and screw the assemblies into the hot water outlet and cold water inlet ports on the top of the tank’s tank’s tank’s tank. Make use of short, plastic-lined nipples to protect your pipes from galvanic corrosion, especially if you have hard water or if they are required by your local building standards. Step 6: Organize your thoughts and feelings about the situation.

Attach the water lines

Slide the new water heater into position, recut or lengthen the old tubing to connect it to the new, and solder the tubing together using copper slip couplings to complete the installation. If the tubing does not line up properly, use pairs of 45-degree elbows to adjust the alignment of the lines. Step 7 – Organize your time and resources.

Reattach the vent

Reconnect the vent if necessary. Place it securely over the draft hood and secure it with three 3/8-in. No. 6 sheet metal screws to hold it in place. Prepare the holes by drilling them beforehand. Before turning at the first elbow, the vent should rise at least 12 inches vertically from the floor. In this eighth step, you will learn how to use a comma to separate the words “and” and “and not.”

Use two wrenches to attach the gas line

Reconnect the gas line if necessary. Pipe joint compound should be applied to the threaded ends before screwing the first nipple into the gas valve. To minimize straining the valve, use two pipe wrenches at the same time. Reassemble the remaining nipples, concluding with the union at the end of the process (Photo 2). Then, in order to fill the tank, perform these four steps: To check for leaks, perform the following steps: (1) cut off the main water valve; (2) re-connect the water at the main shutoff; (3) open the cold-water valve on the water heater (but do not close it); and (4) turn on a nearby hot-water faucet until water flows out.

Check for backdrafting

The majority of water heaters rely on a natural airflow to carry combustion emissions up the chimney and out of the building. If the draft does not operate, the fumes, which may contain lethal carbon monoxide, will be released into your home and cause you to become sick. Check the draft when you’ve finished installing everything. Close all of your external doors and windows, and put on the exhaust fans in your kitchen and bathroom. Continue to run a hot water faucet until you hear the gas burner in your water heater come to life.

Ideally, the smoke should be drawn upward through the vent pipe. If the smoke does not draw, this indicates that the burner’s fumes are not escaping. Turn off the gas supply to the water heater and contact a certified plumber to diagnose and remedy the problem. Step number ten.

Check for leaks

Check for leaks by turning on the gas and squeezing a 50-50 combination of dishwashing liquid and water over the connection points. If there are bubbles in the mixture, you have a leak. Joints that are leaking should be tightened or reconnected. When you’re finished, wipe the joints down with a clean cloth. Make an appointment with the plumbing inspector to have them go at your work. Follow the how-to instructions that are included with the photographs to ensure that the connections are secure.

Light the pilot light

The pilot light should be turned on in accordance with the manufacturer’s instructions. (When using an electric water heater, turn on the electricity at the main panel after your work has been checked by the electrical inspector). Once you’ve finished, adjust the temperature to 120 degrees Fahrenheit according to the installation instructions. The pilot light in the new water heater should be lit, then the temperature setting should be adjusted.

Installation Details for Electric Water Heaters

At your main electrical panel, turn off all power to your water heater, then turn it back on. After that, empty the water heater in the same manner as you would a gas water heater. As soon as the water heater has been drained, separate the electrical wires from the screw terminals under the access panel, which is normally situated towards the top of the water heater. To handle all of the electrical wiring, you should engage an electrician if you don’t have any prior knowledge with it. When it comes to wiring the new water heater, follow the manufacturer’s instructions.

How to Dispose of a Water Heater

In this video lesson, Jeff Gorton, an editor at The Family Handyman, will show you how to remove and dispose of a water heater in the proper manner. He will also demonstrate a simple method of transporting a water heater out of your home, even if you are working on your own.

These tips will make your work go faster and easier:

  • To avoid modifying the length of your water, gas, or electrical lines, take note of the height of your existing water heater and get a new one that is the same height
  • On older water heaters, the drain valve (Photo 2) frequently becomes clogged. Please be patient if the water drains slowly. WARNING: The temperature is really high! TIP: Turn off your water heater two hours before you want to use it to enable the water to cool. Water heaters are around 150 pounds in weight. When you’re moving the old one out and wheeling the new one in, you’ll need a strong partner or a dolly to assist you. Ordinarily, garbage collection agencies charge approximately $25 to remove the old one. Before you begin, go to a plumbing supply or hardware store, or a home center, and purchase the equipment and materials seen below. Check the sizes of the water supply pipes (the majority will be 3/4 in., as shown in our photographs) and purchase the fittings that are the proper size. If you have everything you need, you should be able to complete the work in four to six hours (provided there are no major problems!). This safety mechanism, which controls tank pressure and prevents it from bursting, is located in the tank’s pressure relief valve assembly (Photo 4). It is necessary to include a fresh one with each installation. The discharge pipe must be kept clear of impediments in order for the valve to function correctly (see Fig. A). Use 3/4-in. plastic-lined nipples (about $2 each
  • Photo 5 and Fig. A) to attach other metals, mainly copper tubing to the steel tank, in areas where the water is highly mineralized or where it is needed by municipal laws. This has the effect of slowing rusting. In order to avoid heating the tank itself during soldering, solder the copper fittings before screwing them to the tank (Photo 5)
  • Slip couplings should be used to link the existing and new water lines (Photo 6). (Photo 6). They do not have an internal stop, in contrast to normal couplings. Alternatively, you may slip them on, align the copper tubing, then slide them back and center them over the junction
  • However, the new inlets and outlets on the tank don’t always line up with the old supply lines, and vice versa. If required, solder in a pair of 45-degree fittings to ensure that each line is offset. While you’re doing it, you should also replace the old cutoff valve with a new ball valve (Photo 6). The diameter of the vents is determined by the amount of heat produced by the water heater. In order to achieve the ideal draft, you may need to raise or reduce the ventilation size. CAUTION: If you’re not sure whether or not your chimney has a liner, consult with a plumbing inspector. Make gas connections using solid steel pipe (Photo 8) or soft copper tubing with flare fittings (Fig. A). Both are more dependable and less expensive than flexible stainless steel connections, which are not usually allowed in some applications. For the same reasons, rigid copper water supply lines should be used rather than flexible copper water supply lines
  • If your water heater replacement is located in a location where leaking might cause damage to the floor or other elements of the home, lay a pan of an appropriate size beneath it (metal for gas water heaters). a drain tube that connects to a home drain or another suitable site must be installed in the pan (outdoors where permitted). If a leak might cause damage to the flooring, the discharge tube for the temperature and pressure relief valves must also connect to a drain. If routing is a problem, consult with your local plumbing inspector about possible solutions. Special straps should be used to secure your water heater to the wall if you reside in an earthquake-prone location (Fig. A
  • Available at plumbing stores and home centers). If they are necessary, your plumbing inspector will inform you of this. Ensure that the new water temperature setting does not exceed 120 degrees Fahrenheit to avoid scorching

7 Steps to Install Electric Water Heater

You may be facing high utility expenses as a result of your gas heater consumption. Do you believe that your electric water heater has reached the end of its useful life and that it is time to replace it? The demand for hot water is considerable in practically every home, with energy consumption for water heating estimated to account for 17 percent of total energy consumption. Electric water heater installation is not inexpensive, even though there are many house specialists and electricians available to help you with it.

In this article, we’ll teach you how to install an electric water heater in your house with only a few simple items you already have on hand.

How to Install Electric Water Heater

An electric water heater installation can be difficult, but with a little understanding of both plumbing and electrical work, you should be able to do the job yourself if you follow our instructions carefully.

Materials and Items Required

Before we get started, make sure you have all of the equipment and resources you’ll need to complete your project in a timely manner. The following are some of the tools you will require:

  • Protective gloves, a voltage tester, a soldering iron, a pipe cutter, a screwdriver, a wrench, pipe dope, and hose

Step-by-step Guide on Electric Water Installation

If you are replacing an old electric water heater because of a malfunction or another, you must first remove the old unit. Using a circuit breaker device, disconnect the power supply for your electric water heater from the unit. After then, the tank will be drained. We’ve created a piece about how to empty a water heater, which you can find here. Drain the tank by turning off the valves and attaching a hose to the tank. To remove the remaining connecting components, use any of the available tools, such as a screwdriver, tubing cutter, or pipe wrench, as needed.

Step 2: Disconnect the electric wire

Removing the electrical cords from the upper portion of the electric heater is the first step. Check to make sure that the circuit breaker in the breaker box is turned off. Before starting, check the wires with a voltage tester to ensure they are in good condition. Capping off the wire and inserting a mark or labeling will help to avoid any mistake at a later time. Another option is to snap a photograph.

Step 3: Disengage the supply pipes

Cut the hot and cold water supply pipes to disconnect them from the rest of the system. This is especially important if the manufacturer utilized copper pipe to connect your water heater to the rest of the house. Cutting with a tubbing pipe or a cutter is the best option. Also, leave a sufficient section of the tube to allow for simple repair, and you may remove the discharge pipe that is attached to the T P Valve if necessary. To connect the cold water intake, you may also use a soldering iron to connect the copper pipes to the cold water supply.

Step 4: Reconnect the electrical wires

Open the junction box cover to get access to the electrical connections and connect the ground wire to the green ground screw on the back of the junction box cover.

Connect the cables together by twisting them together with wire connectors. Take as a guide the previous wiring connections, and reconnect the wires in the same manner as they were before you started working on it. In addition, the junction box cover must be replaced.

Step 5: Install the supply lines

Make certain that the supply line is connected and that the water is turned on. Connect the hot and cold water supply lines at the same time. The cold water pipe should be connected to the cold water input for the water heater. In the event that your previous water was delivered by copper pipe, you can disregard the new water piping. In the event that you live in an earthquake zone, try installing seismic straps to keep the stud in place with a ratchet and socket.

Step 6: Attach the Pressure Discharge Pipe and Temperature

If a replacement T P relief valve is not already installed, it is recommended that you do so. It is not suggested to use a faulty valve. By automatically opening if there is an excessive amount of pressure or temperature, the T P valve helps to avoid costly repairs. You should double-check the amount of time your electric water heater is in use. Afterwards, thoroughly clean the pipe end and the fitting before connecting it to the joint. To join the pipe, solder it together and use a torch to heat it.

Step 7: Switch on the circuit breaker

Turn on the circuit breaker located at the main power box if necessary. The following steps should be completed once your water heater has been filled with water. Warning: Turn off the electricity until the tank is completely filled. If the electric elements are not completely immersed, it is possible that they will dry fire. If you find that your water heater is not receiving electricity, turn off the circuit breaker before inspecting the electrical connections for problems. Allowing the hot water tap to run for a few minutes will help to get rid of any trapped air in the tank and piping.

Prevent the temperature from rising over 120 degrees Fahrenheit.

Because of the high pressure, the pipe may drip.

NOTE: Make sure to follow the instructions in your handbook, since the processes may change depending on the type of your electric water heater.

How an Electric Water Heater Works

Circuit breakers at the main power distribution box should be turned on first. Ensure that your water heater has been completely filled with water before continuing. Precaution: Do not turn on the electricity until the tank is completely filled. If the electric elements are not completely immersed, they may catch fire and cause a fire to burn out of control. Check electrical connections before turning off the circuit breaker if you realize your water heater isn’t getting electricity. Allowing the hot water tap to run for a few minutes will help to remove any trapped air from the tank and piping.

The temperature should be set at 120 degrees Fahrenheit.

Depending on the high pressure, the pipe may drip. In order to assist you with your learning, below is a short video guide: BE SURE TO READ YOUR INSTRUCTION MANUAL CAREFULLY since the instructions may vary depending on the model of your electric water heater.

Application of Electricity in Water Heater

Electric water heaters are available in a variety of configurations, depending on whether or not a container is included, as well as how the heat is generated. They are as follows:

The Tank-Type Water Heater

Your home is most likely equipped with a tank-style water heater. It is the most common type of water heating system seen in modern homes today. Depending on the model, a tank-type water heater can be powered by gas or electricity. The latter, on the other hand, is significantly more expensive to operate, making an electric water heater an excellent alternative. A tank-type water heater is distinguished by the presence of an insulated storage tank that can contain both cold and hot water, depending on the needs of the household.

When compared to tankless water heaters, tank-type water heaters retain less water and use more energy to maintain the same temperature.

Tankless Water Heaters

The water heater in your home is most likely of the tank variety. It is the most common type of water heating system used in modern residences. Depending on the model, a tank-type water heater can be powered by either gas or electric power. Running the former, on the other hand, is significantly more expensive, making an electric water heater a wise investment. A tank-type water heater is distinguished by the presence of an insulated storage tank that can contain both cold and hot water, depending on the needs of the household or business.

Compared to tankless water heaters, tank-type heaters contain less water and require significantly more energy to keep the temperature constant.

Hybrid Water Heater

When a hybrid water heater is installed, it is fitted with an electric heat pump that draws heat from the surrounding air through a small compressor and evaporator coil. The heat is subsequently transferred to the entering cold water using a heat exchanger. When compared to a traditional water heater, it saves 60 percent on energy use.

Why Should You Consider Electric Water Heater?

You’re undoubtedly aware that an electric water heater isn’t the only type of water heater that can be used in your home. Some are powered by gas, with a propane tankless water heater serving as an excellent example. Although the electric water heater has several advantages, we have highlighted some of its disadvantages below. When compared to the other types of water heaters available on the market, an electric water heater is the most cheap alternative in terms of the initial investment required to purchase one.

Installing a gas water heater will necessitate the installation of additional piping as well as the installation of an additional ventilation system, which will aid in the ventilation of the exhaust generated during the combustion process.

When installing an electric water heater, there is no need to do this, which makes the installation process much more simple.

Assuming that a typical residence is connected to the electric grid, it is possible to install an electric water heater. A gas water heater, on the other hand, cannot be installed until your home has been linked to a natural gas or propane supply source. This may be really expensive. Gas-powered appliances, such as water heaters, are susceptible to gas leaks; this is not an exception. Despite the fact that an electric water heater has its own set of safety considerations, the likelihood of suffering any electrical safety issues is far smaller than the likelihood of experiencing a gas leak.

In terms of the quantity of fuel or energy required to create hot water, it is a figure that assesses the efficiency of a hot water heater.


You should have gotten the hang of how to install an electric water heater by now. The procedures are easy, and you may put them into action with relative ease. What makes it even more intriguing is that it is something that anybody can perform as long as they have a basic understanding of plumbing and electrical installation. In addition, you must be able to adhere to the guidelines. It not only allows you to save more money as compared to utilizing gas, but it also helps to increase the overall efficiency of your water heater.

  • Disconnecting the water heater’s electrical supply at the electrical panel is recommended. Utilize a voltage detector to inspect the electrical wiring of the water heater to ensure that no electricity is being sent to the device.
  • Label the wires with tape to indicate the order in which they are joined. Disconnect the cords from the computer
  • Pour hot water into a sink and leave it running until the water cools
  • Immediately turn off the cold water supply to the water heater.
  • Connect a garden hose to the drain valve to drain the water
  • Activate the valve and let the tank to empty
  • Let some fresh air in through the tank’s faucet.
  • Removing the T P discharge line from the T P valve is the first step. Remove the discharge pipe and store it for later use.
  • Disconnect the water supply lines
  • Remove the old tank using a hand truck
  • And replace the new tank.

Step 2: Install the New Water Heater

  • Placing the new tank into a drain pan is recommended. The T P discharge pipe should be connected to the T P valve.
  • Plumbing tape should be applied to the nipples of the hot and cold heat traps.
  • Connect the flexible hoses to the hotcold heat trap nipples using the hose clamps. (If necessary, dielectric fittings should be used.)
  • Plumbers tape should be applied to each end of the connection body threads.
  • The connection body should be connected to the flexible hose at one end.
  • Holding the hose to the pipe (with a little slack in it) and marking and cutting the pipe
  • . Remove any burs that may have formed on the cut pipe
  • Compression nut is inserted into the pipe by sliding it on. Compress the pipe into the connection fitting and tighten the compression nut
  • This will prevent the pipe from leaking. Install earthquake straps to protect your home.

Compression nut is inserted into the pipe by sliding it in. Then, using your fingers, force the pipe into place against the connection fitting and tighten it with the compression nut. earthquake straps should be installed.

Step 3: Fill the Tank with Water

  • Removing the aerator from the nearest faucet and turning on the hot water side will do this. Start by turning on the cold water supply to the water heater and inspecting it for leaks
  • Fill the tank to the brim with water. A full tank of water is indicated by the running water from an open tap. Continue to leave the faucet open until the sputtering stops. Do not connect the electrical wire until the tank is entirely filled with water
  • Otherwise, the tank will overflow. Remove the lid from the junction box and connect the green ground wire to the green ground screw on the junction box.
  • Wire connectors should be used to twist the wires together. Follow the labels on the wires that you labeled when you removed them from your old water heater and reconnect them. Activate the power at the electrical panel by removing the junction box lid and turning on the power. Make careful to switch off the power at the electrical panel before examining your connections if your water heater does not have electricity if it does not have power.
