How To Replace A Hot Water Heater - ERNIEGRAVES | Process Measurement & Control

Learn How to Install a New Water Heater

Because professional installation may easily add $500 or more to the cost of replacing a traditional tank-style water heater, many homeowners are naturally interested in the option of doing it on their own. Furthermore, while it is considered an advanced project, DIYers with sufficient skill may frequently do the task themselves with a little forethought. It’s crucial to highlight that this is not a project for those who are just getting started. Examining the type of water heater you already have is the first step in learning how to install a new water heater in your home.

Then decide on the size: 30-, 40-, 50-, or larger-gallon containers.

You might consider upgrading to a larger unit if your old one did not provide enough hot water.

However, there must be enough space for the larger heater, the flue size must be correct with proper pitch, and the gas line supplied must be sufficient for the heater’s capacity.

Plumbers bid jobs on the basis of a full day’s worth of labor, however, because the project typically grows more intricate as time goes on.

If you’re not sure in your abilities in these areas, hiring a professional is the best course of action.

When it comes to dealing with gas lines, it’s important to always abide by municipal regulations.

Gas Water Heater Venting

It has been usual practice for many years to use atmospheric venting to vent the combustion exhaust fumes from a gas-fueled water heater. In this arrangement, a metal draft hood mounted on top of the water heater directed exhaust gases and a small quantity of fresh air from the room up a metal flue that ran through the roof or into a shared chimney, depending on the model. In many circumstances, connecting an existing flue and draft hood to a new water heater will be all that is required; nevertheless, there are other elements (such as the pitch and draft of the connections) that can make the operation considerably more involved than it appears.

However, the building code in some localities may demand that a new water heater be vented using a different method every time one is installed.

When living in an air-tight home, this is frequently essential to prevent the gas and airflow via the water heater flue from causing an air pressure differential, which can suck gases from the water heater burner into the dwelling.

This is seldom an issue in older, less air-tight houses, though. The process becomes more difficult if your code dictates that you upgrade from an atmospheric vent to a forced-air direct vent or powered direct vent. The majority of folks should hire a professional for this type of service.

Warning

All plumbing installations must be in compliance with the local plumbing code, so check with your local building authority to find out what is required in your region. Because installation varies depending on the location and the kind of heater, the following procedures are intended to serve as a general guideline only and may or may not apply to your specific case. As previously indicated, it is preferable to leave this process to the pros.

Materials

Purchase of a new water heater, as well as any necessary shimming, plumbing fittings, and plumber’s pipe-seal tape. a draft cowl for the water heater (if one is required for a gas heater)
Temperature and pressure relief valves (if not already given)
A drain valve for the water heater (if not already provided)
Fittings for vent pipes (where required)
Nipples for galvanized water heaters with a plastic liner (2)
Flexible water heater tubing (if required)
Flexible gas heater tubes (if required)

Shut off the Water, and the Gas or Electricity

Turn off the power to the existing water heater and disconnect the water heater’s plumbing. Turn off the water at the main water cutoff valve in the home or at a branch shutoff valve that controls the cold water that runs to the water heater in the basement. Then turn off the electricity or gas to the building. For an electric water heater, follow these steps: Turn off the circuit breaker for the water heater’s circuit in the breaker box for the house. a. This is normally a double-pole breaker with a 30-amp rating. For a gas water heater, turn off the gas supply at the shutoff valve on the gas line that is closest to the water heater and then turn on the water heater. Water main should be shut off at the water meter. Home-Cost.com

Drain the Water Heater Tank

A garden hose should be connected to the drain valve located towards the bottom of the water heater. Open the nearest hot water faucet, such as the one in the bathroom, to avoid suction from building up in the line, which can cause the draining to become sluggish. Place the other end of the hose over a floor drain or direct it to an open area outside. To prevent silt from clogging the drain valve, open it carefully when first turning it on. Allow the tank to empty entirely before turning off the valve and removing the hose from the tank. It is positioned at the bottom of the water heater, near the drain valve.

Disconnect the Water Lines

Disconnect the hot and cold water lines from the water heater by using a pipe wrench or channel-lock pliers to tighten the connections. Flexible tubes (usually coupled with compression or union fittings) or soldered connections (soldered connections must be cut with a tubing cutter) can be used to connect the water lines to the heater.

Disconnect the Electrical or Gas Lines

Next, the water heater’s power source must be unplugged from the mains power supply. For an electric water heater, follow these steps: Removing the cover from the wire connection panel at the top of the water heater will reveal the wire connections. Check the individual wires with a non-contact voltage tester to ensure that the circuit is off, and then remove the wire connectors that link the circuit wires to the water heater leads. Remove the cable from the connection box by unscrewing the cable clip and pulling the cable out. For a gas water heater, follow these steps: Remove the gas line from the water heater and make sure the main gas line valve is turned off before reconnecting it to the gas control valve. Depending on the kind of water heater, this gas tube may be a flexible tube covered with vinyl or bare soft copper tubing, or it may be an older water heater with a hard black-pipe connection.

Disconnect the Water Heater Vent (Gas Heaters Only)

The vent pipe should be disconnected from the draft hood located on the top of the heater. In most cases, three or four sheet metal screws are used to attach the draft hood to the exhaust vent pipe. In certain cases, if the draft hood is in excellent condition, it may be possible to repurpose it with the new water heater.

Swap the Old Water Heater for the New

Use an appliance dolly with straps to move the old water heater out of the way and wheel in the new water heater. The use of a helper is recommended while moving water heaters up and down basement steps. When transferring the heater, make sure you tie it to the dolly with strong straps. Clean up the area on the floor where the old heater used to be. Bring in the new water heater and align it with the existing plumbing connections so that it is connected to the water heater’s plumbing system. Shimming beneath the legs of the new water heater can help to level it if necessary.

Tip

If you live in an earthquake-prone area, there may be brackets or straps that need to be attached to the wall to keep the water heater from moving about while in use. The water heater should be installed. Getty Images

Install the Relief Valve and Other Fittings

Install all of the necessary fittings that are required for the water heater to function properly. This always comprises a temperature and pressure relief valve (also known as a TPR valve) as well as a drainpipe for discharge. Follow the manufacturer’s instructions to install any additional fittings that may be required. Relief valve for high temperature and high pressure

Connect the Water Lines

Tie galvanized plastic-lined nipples to the cold water input and hot water outlet ports on the top of the water heater using stainless steel screws. In order to install the nipples, you must first cover the threads with plumber’s pipe-seal tape before threading the nipples into the apertures and tightening them using channel-lock pliers or with a pipe wrench. Connect the cold water pipe to the intake nipple on the water heater, and the hot water pipe to the output nipple on the water heater to complete the installation. In some circumstances, reattaching the flexible tubing that were removed after removing the old heater might be as simple as plugging them back in. When the water pipes are hard-piped into the water heater and cutting is necessary to remove the water heater, the operation becomes a little more difficult. The water heater nipples will be connected to the cold and hot water pipelines through the use of different threaded adapters, short sections of pipe, and union fittings, which will need assembly. The method you use will be determined by the type of pipe you have and the layout of your plumbing system, among other factors. If you have copper pipes, you may need to sweat-solder them together with a torch, but there are compression fittings, grip-fit (SharkBite) fittings, and PEX fittings that can be used with a variety of plumbing pipes. The installation of flexible tubes to link the hot and cold water pipes to the water heater is a suitable time to do so if you do not already have them in place. The water heater will be more easily disconnected if you ever need to repair or replace it in the future. Male-threaded adapters must be attached to both the water heater nipples and the ends of the hot and cold water pipes in order to do this. The flexible tubes are then threaded into the adapters and secured using coupling nuts that screw into the adapters.

Connect the Gas or Electrical Lines

Connect the gas or electricity sources, depending on their location: For a gas water heater, follow these steps: Connect the gas line to the control valve for the gas burner. Use a flexible gas line if it is available and permitted by local regulations. Check for leaks by turning on the gas supply valve and scrubbing the gas union and any gas joints with a soapy water solution until they are clean. If you notice any bubbles, this indicates that the connection is leaking and that it needs to be tightened. If you are still unable to achieve a satisfactory seal without bubbles, contact your gas provider or a plumber for assistance. For an electric water heater, follow these steps: Connect the electrical cable to the water heater’s wire connection box, which is located at the top of the water heater. Wire connectors should be used to connect the circuit wires to the water heater lead connections. The cover plate for the wire connection box should be attached.

Reconnect the Vent (Gas Heaters Only)

The draft hood should be installed at the top of the water heater, centered above the exhaust aperture, and then inserted into the exhaust pipe. Sheet-metal screws are used to hold it in place. You may need to reduce the vent pipe if the new water heater is higher than the old one. You may accomplish this by cutting the vent pipe down to size using metal shears or by installing a shorter pipe segment. Another option is to lengthen the vent by installing an additional vent pipe segment if your water heater is less than the standard length.

The new water heater should come with its own set of parts and operating instructions.

Tip

Shared venting with a chimney or flue that simultaneously serves a furnace (as seen above) is no longer permitted in some municipalities. This means that you may need to hire a professional to reroute the venting for your new water heater in this situation. Getty Images

Complete the Installation

Connect the hot water faucet to a distant position in the home, then turn on the cold water supply valve to the water heater, allowing the water heater tank to fill with water until the hot water tap is turned off. When water begins to flow from the hot water faucet, you’ll know the tank is completely full. Turning the circuit breaker back on for an electric water heater will re-energize the circuit that supplies electricity to the water heater. If you’re using a gas heater, make sure the main gas valve is open and that the pilot igniter is functioning correctly by following the manufacturer’s instructions. Make your chosen temperature selection on the water heater’s thermostat (120 degrees Fahrenheit is suggested), then wait for the water in the tank to get up to temperature before using it. Turn on the heater and adjust the temperature of the water heater. Banks Photographs courtesy of Getty Images

Introduction

When your water heater begins to leak, you must act quickly to have it repaired or replaced. We’ll teach you how to set up your own natural gas water heater in less than a day’s time. 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.

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.

Fire pipe, cold water shutoff valve, draft diverter, temperature and pressure relief valve, overflow pipe, hot water outlet, anticorrosion anode rod, dip tube, elements, insulation, drain valve, thermostat or control valve, burner, thermocouple, gas supply valve, and more.

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

Shut off the water heater by first turning off the electricity at the main electrical panel. Then, much like with a gas water heater, drain the tank using the same process as above. When the water heater has been emptied, separate the electrical wires from the screw terminals under the access panel, which is normally situated towards the top of the water heater body. To handle all of the electrical wiring, you should engage an electrician if you don’t have any knowledge. When it comes to wiring the new water heater, follow the manufacturer’s instructions.

A unique approach must be taken with aluminum wire.

Contact a licensed professional who is familiar with aluminum wiring if you have any. Unlike copper wire, which is typically orange, this wiring is a dull gray color instead of the typical dull orange color. Step 12 – Organize your time and space effectively.

These tips will make your work go faster and easier:

To begin, cut off the electricity to the water heater at the main electrical panel in your home. Then empty the water heater in the same manner as you would a gas water heater. When the water heater has been drained, detach the electrical wires from the screw terminals under the access panel, which is normally situated towards the top. To handle all of the electrical wiring, you should engage an electrician if you do not have any prior knowledge.) When it comes to wiring the new water heater, follow the manufacturer’s recommendations. Install a 4-in. x 4-in. x 1-1/2-in. metal electrical box on the wall or ceiling near the water heater, feed the old wires to the box, and then run a new piece of armored cable or electrical conduit to the water heater. Consult with the manufacturer’s instructions to ensure that the existing fuse or circuit breaker has a rating sufficient to handle the new water heater. In addition, the circuit should have a shutdown switch that is visible from the vicinity of the water heater. Before you begin the project, make a phone call to your local electrical inspector. It’s likely that you’ll require a permission. Afterwards, after you’re completed, have the electrical inspector come in and go over your work. Aluminum wiring necessitates the use of unique techniques. If you have aluminum wire, you should bring in a qualified professional who is experienced in working with it. Unlike copper wire, which is often orange, this wiring has a dull gray color instead of the typical orange of copper. ‘Step 12’ is the last step in the process.

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.

When to Replace a Water Heater

There is a possibility that you can fix your current water heater if it is leaking or not heating up properly. When the time comes, learn how to recognize the indicators that your water heater has to be replaced completely.

How Long Do Water Heaters Last?

According to the manufacturer’s recommended service life, the life expectancy of a water heater is between eight and twelve years on average. That varies depending on the unit’s location and design, the quality of the installation, the maintenance schedule, and the quality of the water. Generally speaking, if your water heater is more than 10 years old, if it leaks at the base of the tank, or if it operates irregularly, it’s time to consider replacing it. You might also choose to upgrade to a more energy-efficient model in order to reduce your energy costs.

Before you begin looking for a replacement, check to see whether an electrical problem, such as a blown fuse or a tripped breaker, is the source of the unit’s failure.

Troubleshooting Common Issues

One of the most typical issues that arises with a water heater is that the water does not heat up as quickly as you would like it to. This is typically caused by a faultythermostator or a malfunctioning heating element in the boiler. When your water isn’t hot enough, have a look at the following.

Electric Water Heater

Check to see that the electricity is connected and that the thermostat has been reset. Flush the heater to remove any sediment that has accumulated in the tank. Ensure that the hot water lines are properly protected. Replacing the heating element or thermostat is a good idea. The thermostat’s temperature setting should be increased.

Gas Water Heater

Check to see that the gas is turned on and that the pilot light is lighted. Flush the heater to remove any sediment that has accumulated in the tank. Ensure that the hot water lines are properly insulated. Clean the gas burner and repair the thermocoupler (a safety mechanism that immediately turns off the gas if the pilot flame goes out)
The thermostat’s temperature setting should be increased.

Water Heater Maintenance

Although today’s water heaters are designed to require little or no care, following these maintenance guidelines may help you extend the life of your water heater. For further information on how to maintain a water heater, see How to Maintain a Water Heater.

Drain the water heater twice a year to get rid of the silt that has accumulated and is causing corrosion. This also boosts the efficiency of the system. Activate the pressure release valve by raising the handle and allowing it to snap back into position. Upon doing so, a burst of water should be released into the overflow drainpipe. If it doesn’t, replace the valve with a new one. Reduce the temperature setting on the thermostat to 120 degrees Fahrenheit to keep the house comfortable. Overheating can cause damage to the tank, therefore this helps to minimize such harm.

When Replacement Is Necessary

If you’re replacing a water heater, you can use the same sort of device as the one you’re replacing. However, you might want to think about upgrading to a bigger tank or a tanklessheater as an alternative. When shopping for a water heater, keep the following qualities in mind:

Heaters with a capacity of 40-gallon or 50-gallon are the most commonly encountered
In gallons per hour, the recovery rate refers to the number of gallons heated by the heater. In terms of dimensions, depending on where you intend to put the unit in your home, you may require a specific width and height
Ratings for energy efficiency: A label on the side of the unit shall display the projected yearly cost of operating the unit in dollars. Models with high energy efficiency can help you save money and energy.

In order to determine if you need to make repairs or purchase a new water heater, look at the nameplate on the side of your present unit. You’ll discover useful information like as the tank capacity, insulation R-value, installation instructions, working pressure, model, and serial number in this section. It is also possible to get information on your electric water heater’s wattage capacity and voltage on the nameplate of the heater itself. If you need replacement components or a new water heater, you may use this information as a starting point in your search for them.

Read our Water Heater Buying Guide for assistance in selecting a water heater, and then consider the following considerations to assess whether or not you wish to attempt water heater installation yourself:

What plan do you have for getting rid of your old water heater? Check your local codes to see how such equipment should be disposed of. Will you be able to manage the device on your own physical terms? Water heaters are large and hefty appliances. You’re going to require assistance
Do you have all of the tools you’ll need to complete the job? Water heater installation necessitates the use of adjustable wrenches, screwdrivers, a hack saw, and pliers among other tools. If your copper pipe installation necessitates the use of a propane torch, you may also require one. Do you have the necessary time to complete the task? Once you begin replacing a water heater, you must see it through to completion.

Please see our articles on How to Install an Electric Water Heater and How to Install a Gas Water Heater for further information on how to replace a water heater in greater depth.

How Long Will Hot Water Tanks Last?

Water heaters with hot water tanks are the most common form of water heater. They are powered by gas or electricity and heat incoming water to a temperature you choose before storing it in an insulated metal tank until you want it once again. The life of tanks may be prolonged by flushing them once a year and replacing the anode rods every three years. Residents of Ottawa who use city water may expect to live for around 10-15 years.

How Long Will Tankless Water Heaters Last?

Tankless water heaters are more recent technology that heats water only when it is needed. Due to the fact that tankless heaters do not contain water, they tend to survive far longer than tanks. Unless tankless systems are cleansed routinely every year on well water and every 2-3 years on city water, their life expectancy will be significantly shortened. They will last longer if sediment filters are installed prior to the water input, and they will last longer if water treatment systems are installed to lessen the hardness of the water in locations with hard water.

Common Water Heater Issues

Be on the lookout if you detect any of these problems. You should get your water heater repaired or replaced as soon as possible if you see any of these warning signs. Please follow the steps outlined below to troubleshoot your problem; if this does not resolve the problem, you will require expert water heater servicing.

Hot Water Is Too Hot

Whether your hot water is suddenly considerably hotter than normal, first check to see if the temperature of your water heater has been unintentionally reset by someone else. (Ideally, the temperature should be 49 degrees Celsius.) Also, make sure that the thermostats are set tightly against the tank in order to get an accurate measurement of the temperature. If nothing of these measures resolves the problem, you most likely have a faulty thermostat, which should be replaced by a professional.

Hot Water Is Not Hot Enough

Perhaps you have the polar opposite problem: hot water that never seems to get up to anything more than lukewarm. Check once again that the thermostat is set to the proper temperature and that it is firmly placed before proceeding.

If those tests come up negative, you may require a replacement item, such as a dip tube or heating element. or a new water heater. We will evaluate your water heater and advise you on whether repair or replacement is the most cost-effective solution for your situation.

Water Heater Leaking

The lazy src property is used in conjunction with the lazy method and the lazy attributes srcdoc and src. The source of a water heater’s leakage might be one of numerous possible locations. Do you want to be your own amateur detective? Investigate the source of the leak to determine its cause. Before you begin, switch off the gas or power to your heater, as well as the water supply to it. Afterwards, inspect the pressure relief valve, drain valve, input valve, and outlet valves. If any of these components is leaking water, it is likely that it may be repaired or replaced.

Most likely, the tank has deteriorated, necessitating the installation of a water heater replacement unit.

Noisy Water Heater

The sound of a water heater that pops, rumbles, hisses, or sizzles is an indication that something is wrong with it: specifically, that your water heater need immediate care. It’s possible that you have an issue with water flow or water pressure. More frequently, silt from waterborne minerals has accumulated to a dangerously high concentration. However, if the problem has been ignored for an extended period of time, water heater replacement may be the only option. Flushing the system (for tankless heaters and tanks) may be the sole cure.

Hot Water Looks Brown

Corrosion inside the tank is typically the cause of a rusty or brownish flow that only emanates from the hot water taps. You should down to the basement and examine your water heater in its entirety. Visible rust on the outside of the heater is a major indicator that it is likely to fail. Call us as soon as possible for water heater replacement!

Should I Replace My Water Heater Before It Fails?

Perhaps your water heater is still operational, but if it is approaching the end of its useful life, it might be prudent to begin shopping for a replacement. Please keep in mind that water heaters, like any other mechanical equipment, have a useful life expectancy. Traditonal storage water heaters have a lifespan of 10 to 15 years, however tankless ones can survive up to 20 years or more in this situation. What are the signs that it’s time to replace your water heater? This information should assist you in making your decision.

4 Reasons to Replace Your Water Heater Before It Fails

For those with limited financial resources, replacing your water heater before it breaks totally may be out of the question. However, the basic reality of the matter is that all water heaters ultimately quit operating. Despite the fact that you want to get the most service life out of your investment, waiting until the appliance breaks down may not be worth the trouble. Here are some reasons why a proactive replacement could be advantageous:

When your water heater breaks, you are forced to make a hasty decision: The last thing you want to do when your water heater breaks down is spend time learning about the differences between traditional tanks and tankless versions. One cannot compare the advantages and disadvantages of natural gas vs electric units, nor can one investigate the idea of using a heat pump water heater. You may not make the ideal decision if you don’t have enough time to consider all of your options. When your water heater breaks, you will be without hot water: A water heater replacement is required in an emergency situation, and you will not have hot water until the new unit can be delivered and fitted. For a number of days, your life and the lives of your family may be made unpleasant by this. The opposite is true in that a planned and scheduled water heater replacement is quick, convenient, and can be completed at your convenience
A rusted water heater might cause severe harm, including the following: A sacrificial anode rod is included with every water heater. In order to attract corroding chemicals in the water and preserve the tank from rusting, this little piece of steel is covered by an aluminum, magnesium, or zinc shielding. If you don’t change this rod on a regular basis, your water heater may begin to suffer from wear and tear. If the tank rusts through, it has the potential to fail catastrophically and flood your residence. By replacing your water heater before it breaks, you may save a potentially disastrous situation. A new water heater may be able to help you save money on your power bills: You will need to make an investment in a new water heater, but the savings on your energy costs will begin to accrue immediately. Because water heating expenditures are second only to space heating and cooling costs in terms of cost, you might see a return on your investment rather fast.

5 Signs that Your Water Heater is Failing

It’s understandable if you want to put off replacing your water heater for as long as possible, but don’t put off getting the appliance serviced if you observe any of the following indicators that your water heater is failing:

A scarcity of hot water
There are strange noises coming from the water heater. Water that is red or brown in color flowing from the faucet
The water heater tank has visible corrosion on it
Pools of water are accumulating around the water heater

Why You’re Freezin’: 5 Good Reasons The cost of replacing your water heater is slightly more than the cost of replacing certain other appliances since installation entails a number of distinct aspects and factors, which include:

According to research from HomeServe, the national average cost to replace a water heater is more than $1,700 on average. Keep in mind that your selected contractor will almost definitely charge you an additional hundred dollars or so for a diagnosis fee, which will be charged regardless of what you decide to do when he or she comes to your home and determines the nature of the problem. The type of water heater you choose to install has the greatest impact on the cost of water heater replacement.

Additional costs, such as a new drain pan, seismic strapping, or exhaust venting, might add several hundred dollars to the total cost of the project.
For example: The total cost of a similar-sized property in Kentucky might be as little as 1,300 dollars, while a homeowner in Idaho may pay about two thousand dollars for the same-sized unit.

What Goes Into the Price You Pay for Installation?

As you can see, the unit itself is the most expensive component of a water heater. However, while determining total expenditures, it is important to take into consideration the cost of installation. The price of components such as pipe fittings, the cost of permits, and the cost of labor will all be included in the installation expenses for a water heater replacement project. When purchasing supplies such as pipe fittings, valves, and connections, expect to pay an additional $8 to $10 per foot in addition to the base price.

Some jurisdictions may not require a permission at all, but others may charge a cost of up to a few hundred dollars to get a permit for the installation of solar panels.

While a plumber is installing your heater, you should expect to pay between $45 and $150 per hour.

Which Water Heater Brands Cost the Most to Install?

Varying manufacturers charge different costs for their heaters, although some brands may design heaters that are more powerful than others. The brands you choose should be ones that offer a good combination of cost, dependability, and durability; this is especially true when it comes to electronics. Consumer Reports has awarded good ratings to A.O. Smith, Rheem, Whirlpool, GE, and Kenmore, among other brands of appliances.

Rheemhas a reputation for being a company that allows you to save money, with tank water heaters ranging in price from $400 to $2,300. A.O. Smithheaters are comparable in performance, however they may cost up to $3,500
Noritz appeals to people who are looking for a more affordable tankless water heater, with units starting as low as $515 on Amazon. Tankless heaters from the Rinnai brand, on the other hand, may cost anywhere from $900 to $1,995 depending on the model.

Are Energy-Efficient Models Worth It?

While attempting to determine water heater pricing, many homeowners question if it is really necessary to consider energy efficiency when making their decision. Most energy-efficient versions will be a bit more expensive than normal ones, but they will promise to make up for that difference in price through lower monthly utility expenses. If you want to know if an energy-efficient model is worth the investment, you should compare its yearly operating expenditures to the operating expenses of cheaper, non-energy-efficient versions that are less expensive.

In general, the amount of money you save will be determined by factors such as your local energy costs and the level of energy efficiency.

The use of a high-efficiency tankless water heater might result in even greater savings, ranging from 45 percent to 60 percent.

How Long Before You Need to Replace Your Water Heater Again?

When estimating overall water heater expenses, it’s beneficial to consider the product’s typical lifespan, which may be found on the manufacturer’s website. The standard hot water heater tank has an expected lifespan of eight to twelve years. Meanwhile, the average tankless water heater has a lifespan of 15 to 18 years on average.

Because tankless water heaters do not corrode as much as traditional water heaters, they last far longer. Due to the tank’s extended life duration, you may discover that paying a greater price up front results in a cheaper cost per gallon over the course of the tank’s whole life cycle.

Signs of Trouble (and How to Avoid Them)

The following are examples of warning indications that your water heater is about to fail:

The tank is emitting banging or rumbling noises. Water that is hot and appears red or yellow
Energy bills that are unusually high
A abrupt drop in the temperature of the hot water
Leaking from the tank’s perimeter

Maintaining your hot water tank on a regular basis, such as flushing it and changing the sacrificial anode rod, can help it survive as long as possible. If you discover any difficulties with your water heater, contact a water heater repair service right enough to avoid more damage. With a little regular maintenance on your tank, you can avoid having to pay for water heater replacement prices any more frequently than is really required in most cases.
