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.

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.

Water Heater Parts and Breakdown

  • 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.

Plumbing codes differ from one location to the next. 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. Instead of making changes afterwards, it is preferable to seek advice early.

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.

Turn off the gas supply to the water heater and contact a certified plumber to diagnose and remedy the problem.

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.

  1. x 4-in.
  2. metal electrical box on the wall or ceiling near the water heater, route the old wires to the box, and then run a new length of armored cable or electrical conduit to the water heater to complete the installation.
  3. The circuit should also have a shutdown switch that is visible from the vicinity of the water heater.
  4. You’ll almost certainly require a permit.
  5. Aluminum wire needs specific care and handling.

If you have aluminum wire, you should choose a qualified professional who is experienced in working with it. This wiring is a dull gray color, rather than the drab orange color that is characteristic of copper wiring. ‘Step 12’ is the final step in the process.

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

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.

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.

  1. Then decide on the size: 30-, 40-, 50-, or larger-gallon containers.
  2. You might consider upgrading to a larger unit if your old one did not provide enough hot water.
  3. 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.
  4. 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.
  5. If you’re not sure in your abilities in these areas, hiring a professional is the best course of action.
  6. 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.


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.


  • 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.

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.


  • 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.


  • 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

  1. 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

8 Water Heater Installation Mistakes and How to Avoid Them

Every day, the average American home consumes more than 60 gallons of hot water. Hot water is so crucial that it accounts for about 20% of the total energy consumption on a monthly basis. Did you know that water heaters have a lifespan of around 10 years? When your water heater reaches the age of around 8 years, it is time to consider replacing it. It is critical to avoid making costly mistakes throughout the water heater installation process in order to prevent wasting your money. If this is your first time purchasing a new water heater, this article will assist you.

1. Underestimating Your Hot Water Needs

Purchasing a water heater that is inadequate in order to save money will result in a higher energy bill. As an alternative, take the time to determine how much hot water your household consumes. The amount of hot water you consume during the busiest period of the day is referred to as your peak hour demand. To figure it out, utilize the following information:

  • Every 10 minutes, the shower uses 10 gallons of water
  • Hand-washing dishes use 2 gallons per minute
  • The dishwasher uses 6 gallons per use
  • And the washing machine uses 7 gallons per use

When selecting a water heater, choose one that can provide a gallon or two more per minute than your peak hour usage. Look for the EnergyGuide label to see what information is available.

2. Ignoring New Technology

Renewable energy sources are being incorporated into innovative water heating equipment. Solar water heaters are an excellent illustration of this. Using the heat from the sun, these heaters warm water for your household.

A solar water heater can reduce your water heating bills by half if you install one. Several types of solar water heaters do not function properly in cold areas. Closed-loop heating systems are the greatest option for households in Michigan since they are more energy efficient.

3. Overlooking Energy Efficient Water Heaters

The cost of a tank water heater has reached an all-time low. The disadvantage of these heaters is that they require a lot of maintenance and replacement parts. Each visit to the repair shop costs around $600. Tankless water heaters are more energy efficient and last twice as long as traditional tank water heaters. Because they do not have a water tank, there is less silt in the system, which reduces the likelihood of rust formation. Tankless systems are avoided by homeowners because they cost twice as much as traditional tank heaters.

4. Failing to Follow Installation Instructions

Installation manuals and building codes are available to ensure the safety of your house and family. Before beginning a water heater installation process, be sure you have read all of the directions. Organize your thoughts and make a list of the tools you’ll need for the endeavor. Missing a single step, such as failing to secure the water heater, can result in catastrophic floods. Flooding encourages the growth of harmful fungus in your house. Mold may also devour porous materials such as drywall and other building components.

The permits ensure that the installer complies with all applicable safety and building requirements during the installation process.

5. Installing the Water Heater in an Inaccessible Spot

When living in a smaller house, finding space for your water heater might be difficult. In certain cases, this leads to homeowners putting heaters wherever there is available space. The water heater may not be maintained as frequently as it should be if it is difficult to have access to it. Rust and sediment seeps as a result of carelessness. Here are a few pointers on where to put your water heater:

  • Keep your water heater within 20 feet of the entryway or crawlspace access
  • Otherwise, it might cause damage. Make certain that the crawlspace hole is large enough to allow for comfortable entry and exit. Installation of enough illumination at the entrance to make maintenance visits more manageable. When it comes to electric water heaters, install a power switch in case of floods.

Installing a gas water heater in an enclosed room that has not been intended for it is not recommended. Carbon monoxide is produced by gas heaters. If your water heater is housed in a closet, it has the potential to harm you and your family.

6. The Drain Line is In the Wrong Position

The TPR valve is located on the side of the water heater tank. When the tank becomes excessively hot or over-pressurized, this valve allows hot water to be released. During the installation process, you will need to connect a drain line to the TPR valve in order to guide the flow of water. The drain line should empties into the nearest floor drain, if one is available. Never connect a drain line to a drain pipe or vice versa. It has the potential to cause polluted water to back up into the water heater.

If the heater vents while being serviced, the spraying water will cause you to burn your skin.

7. Don’t Dry Fire the New Water Heater

Never use an electric water heater if the tank is completely depleted of water. A dry fire is a slang term for this type of blunder. The upper heating element of a dry-fired water heater will be completely destroyed. The cost of replacing parts is quite inexpensive. However, the repair will increase the amount of time your family will be without hot water. Always put water through your electric water heater before turning on the stove to avoid a dry fire catastrophe.

Pour hot water into your kitchen sink by turning it all the way on and letting it run for 3-4 minutes. There are air bubbles in the pipe, which will cause the noises you may hear. You shouldn’t be concerned about them unless they linger for more than a few minutes.

8. Refusing to Ask For Help with Your Water Heater Installation

It is OK to acknowledge that you lack the necessary abilities to finish a home improvement job. Installing water heaters necessitates a thorough understanding of plumbing, electrical, and gas systems. Professionals require years of training to master all of these abilities. Bringing in a professional who is knowledgeable about water heater installation will save you money. In comparison to a dry fire, they are less prone to make mistakes. They also know how to deal with any unexpected complications that may arise throughout the installation process.

Most likely, you do not have the essential tools to deal with any unexpected problems that may arise.

How To Know If Your Water Heater Needs Replaced

When determining whether or not your water heater needs to be changed, there are a few elements to take into consideration. The age of your water heater is the first clue to look for. Your unit should be labeled with an installation date sticker, similar to the ones that are placed on your automobile after it has had its oil changed. Your water heater is more than 10 years old if the date on the tank says so, and you should start making arrangements for a replacement as soon as possible in your budget.

  • The most obvious sign that your water heater isn’t operating properly is that your water isn’t getting as hot as it should. Sediment can get into your unit and build up, causing a separation between the heat source and the water to form. Furthermore, as the silt is heated again and over again, it becomes increasingly hard. When this occurs, you’ll most likely hear them banging around within your water heater, which is a good sign. It is also possible that these hard particles of silt can cause a leak in your unit if you are unlucky enough. This results in a whole new series of difficulties
  • For example, leaks will cause problems with the area around your water heater, which will cause damage to the area around your water heater. You should consider if your water heater will be surrounded by carpet, concrete, or anything else. In certain cases, this might result in a significantly larger replacement effort than simply installing a new water heater.

Can I Install a Gas Water Heater Myself?

You can easily do a gas water heater installation on your own if you’re confident in your abilities; but, if money is your major concern, it may actually be more cost-effective to hire a professional to assist you. The Consumer Reports website states that 90 percent of water heater replacements are necessary because the previous water heater has failed. If you don’t know how to install a gas water heater, you don’t want to have to figure it out when water is gushing all over the place. It might also be dangerous to do it on your own if you have no prior expertise or knowledge of the subject.

A gas leak is not a DIY job you should take on unless you are prepared to take a significant risk to your house and the environment.

What Kind of Water Heater Do I Own?

To correctly install a new water heater, you must first remove the old one that is currently installed. In order to remove a gas water heater, you will have to put up more work than if you are using an electric water heater. Electric water heaters are distinguishable from their gas counterparts by the fact that they are powered by a cord and are not linked to a gas line. Because each water heater is slightly different, it’s a good idea to make a note of the make and model of your water heater as well.

Choosing the Right Water Heater

Pick whether you want to fuel your water heater with natural gas or electricity, and then decide whether you want a tank-style water heater or a tankless water heater. The choice between gas and electric will be the more significant one since it will have the most influence on your monthly energy bill and maintenance expenditures.

Electric Water Heaters

Electric water heaters are the most straightforward to set up. In addition, they are less expensive to acquire. However, there are certain disadvantages to using them. Here are some pros and downsides to take into consideration:

  • Electric water heaters require less maintenance than gas water heaters since they are not linked to a natural gas line. As a result, there is no danger of gas leaks, which can result in explosions or carbon monoxide poisoning. When it comes to the water heater itself, you will save money. Power, on the other hand, is more expensive than natural gas, therefore you will see an increase in your electricity costs as a result of this saving. If you lose power, you will be without hot water for a period of time since the water heater requires electricity to work. Compared to its gas-powered equivalents, electric water heaters heat water at a slower rate. Electric water heaters with high efficiency are not available on the market.

Gas Water Heaters

Installing a gas water heater will necessitate the use of more advanced skills and will take longer than installing an electric water heater. If you’re thinking about installing a gas water heating system, there are some advantages and disadvantages to consider. These include:

  • Natural gas is significantly less expensive than electricity. In order to save money on your utilities, this is the best option for you
  • Units fuelled by natural gas heat water fast. When compared to an electric water heater, a tankless gas water heater is far more effective and efficient. If your electricity goes out, your water heater will continue to run normally without interruption. During storms or other power outages, this may be quite beneficial. Gas water heaters are more costly to install than electric water heaters. However, because they are less expensive to operate, the money you save on your power bill will more than equal the original cost over time.

In addition, there are safety risks associated with having a gas system. A gas leak may necessitate the hiring of a professional to solve the issue swiftly, and you may be exposed to carbon monoxide and combustible gas as a result of the leak. It is possible to alleviate some of the safety issues associated with using a gas water heating system by installing carbon monoxide detectors in your house. The installation, inspection, and maintenance of your equipment should be handled by a qualified specialist.

Check your connections on a regular basis so that you are aware of when you need to make repairs.

The fact is that they are more cost-effective in the long term. You will save more money over the course of the system’s lifespan than you would have saved up front if you had purchased an electrical unit.

Tankless Water Heaters Vs. Storage Water Heaters

The decision on whether or not to go with a tankless unit is dependent on the amount of demand you intend to place on the unit as well as the environment in which you reside. Water heaters with no tanks take up a fraction of the area required by tanks with tanks, but they are unable to store any hot water. However, after the water is heated, they can produce around four gallons of hot water every minute, which is a significant increase over the previous model. Despite the fact that this may appear to be a lot, it may not be enough if you’re also running the shower, dishwasher, and washing machine at the same time.

  1. Another disadvantage of living in a colder region is that cold water takes longer to heat, so if you’re starting with water that comes in from chilly pipes, it will increase the amount of time it takes to warm the water.
  2. Tank systems are significantly more common, and the majority of homes are already equipped to accommodate them.
  3. An unvented tanked system works by continuously heating the water in your storage tank, allowing you to have hot water on demand anytime you turn on the water faucet.
  4. The majority of individuals choose for a tank with a size between 40 and 55 gallons.

How Do I Install a Gas Water Heater?

When dealing with gas lines, the most important thing to remember is that safety comes first. Make certain that your gas and water are totally turned off while you are working in order to avoid mishaps and serious injury. Before using the new system, check to see whether there are any leaks. If you are not familiar with all of the safety standards for installing a water heater, we do not advocate attempting to do it yourself. An installation guide for the most popular form of water heater, a gas unit with a storage tank, is provided in this step-by-step instruction.

Step 1: Measure and Prepare the Space

The most effective method for accomplishing this is to measure the unit you presently own and then purchase a new water heater that matches those measurements. Make certain that the new water heater complies with any applicable local laws or ordinances so that you don’t install it only to discover that you have to remove it because it doesn’t meet the requirements.

Step 2: Cut Off the Water Supply

Close the water main shutoff valve, which will shut off the water supply to your whole home.

In addition, turn the water control valve on the unit itself to the off position. Then, turn on all of your faucets around your house to drain as much hot water as you possibly can from your system. Keep the faucets open while the old unit is being removed.

Step 3: Drain the Tank

Drain the tank by attaching a hose to the drain valve and turning it on. You can direct the water to a location outside your house, or you can dump it into buckets or a drain in your home that feeds to the sewage treatment plant. Even though this procedure may take a few minutes or longer, it’s critical to ensure that the tank is completely empty before proceeding.

Step 4: Disconnect the Gas and the Water

A tubing cutter will be required for this stage, if the lines have been soldered together before. Because your water should already be turned off, begin by turning off the gas to the water heater. If you don’t notice any shutdown valves near the heater, you’ll have to turn off the main water supply to the house instead. If you sand the pipe before disconnecting it, it may be easier to solder the new pipe when you reconnect it. Remove the gas pipes, but leave the tank tee and sediment trap in their original locations for safety reasons.

Step 5: Remove the Overflow Pipe and Pressure Release Valve

These will be linked to your newly purchased unit as well. It will be necessary to disconnect your old water heater from the gas exhaust, but you will be able to keep the vent hood in place. Because it will be so hefty, removing your water heater may prove to be a difficult task. Make certain that you understand how and where to dispose of it before moving anything else around. More information on how to dispose of old water heaters may be obtained by contacting your local trash management organization.

Step 6: Clean the Floor

Make certain that you have adequate room to work comfortably. For adequate ventilation, place the new unit at least 6 inches away from any walls or open spaces. Install the new unit and use a level to ensure that it is sitting flat on the floor.

Step 7: Hook Up the Flue Hat

Install the heat trap fittings and water line connections in the reverse sequence of the removal: first connect the flue hat to the gas exhaust vent, then connect the heat trap fittings and water line connections. In the event that you do not properly install them, your water flow will be disrupted, and hot water will not be delivered to your plumbing system. Make sure you’re feeding the lines in the correct direction by following the directions on the lines.

Step 8: Solder the Gas Line

It will be necessary to solder the pipe to rejoin it if you used a tubing cutter on the gas line during the removal process. It’s also important to reconnect the water supply line. After that, you’ll need to reinstall the pressure relief valve to complete the process. At this stage, you will need to connect the gas line and check it for leaks to ensure that there are no problems. Wash the area with soapy water and check for bubbles if there is any sign of gas leakage.

Step 9: Light the Pilot Light

Finally, re-ignite the pilot light and re-connect the water supply. Make careful to turn off any faucets that were left open prior to this procedure.

Is It Difficult to Replace a Gas Water Heater?

Installing a gas water heater is not normally a do-it-yourself project for most homes; you cannot learn how to install a gas water heater in a day or two. If you are not adequately equipped and have no prior plumbing knowledge, doing this procedure can be highly risky. There are a plethora of possibilities for things to go wrong. In addition, you must ensure that your system complies with all applicable building requirements in your area. We recommend that you use a professional plumber for installation since a plumber will be able to install your unit quickly, will frequently be able to dispose of the old unit, and will be familiar with the standards and regulations that control what sort of system you are permitted to install.

As an added bonus, a professional will do all of the necessary safety tests to ensure that your new water heater is free of leaks, providing you with more piece of mind.

How Long Does It Take to Install a Gas Water Heater?

A competent plumber can generally perform the installation in less than two hours with the proper tools. Given the weight of a tank-style water heater, a plumber may enlist the assistance of a coworker in order to complete the removal successfully. It’s possible that you won’t be able to move the unit on your own. If you have no prior expertise, the procedure might take several hours — or possibly all day — since you will need to spend a significant amount of time making sure you understand where everything is supposed to go.
