Turning Off Electric Water Heater When Not In Use

When You Should Turn off Your Water Heater

When it comes down to it, a water heater is a really straightforward item. You can rely on a tank water heater to provide you with consistent hot water for 10-15 years — all it wants in return is for you to do some routine maintenance on it. However, there are occasions when the unit’s upkeep must be taken into mind. A common question we receive from consumers is, “Do I need to switch off my water heater if.?” The following are responses to three frequent circumstances.

When the main water supply is shut off

It is possible that the main water supply will be switched off in a variety of situations. When this occurs, many homeowners ask if it is safe to leave the water heater turned on or whether it should be turned off as well. Yet, turning off the water heater may not be absolutely essential in the majority of circumstances; however, doing so will not be harmful any way. However, there are two instances in which you should turn off the unit to avoid excessive pressure or heat from building up inside the tank: (1) When the unit is not in use; and (2) When the unit is in use but not in use.

  • The tank is completely depleted (or almost depleted) and will not be replenished for an extended length of time
  • The main water supply is experiencing low pressure

When you go on vacation

When you travel on vacation or anticipate being away from home for a lengthy period of time, you should follow the standard procedures for preparing your house. You may make changes to your heating and cooling systems, program automated lighting, and place a hold on your mail. But what about the water heater in your home? While it may seem rational to turn off the water heater when it is not in use in order to conserve energy, this may not be as advantageous as you may expect. For starters, turning on and off the unit may be disruptive and difficult for the unit.

Instead, use the “VAC” mode on your water heater (which is a typical feature on contemporary water heater types) or lower the water temperature to 50 degrees Fahrenheit.

When there’s a leak

The unit should be turned off and the water supply should be turned off until the problem is remedied. A leak can occur for a variety of causes, including age or a valve fault.

  • Locate the water heater’s piping line, which is normally at or at the top of the unit.
  • 4.
  • 5.
  • Drain the supply by placing the garden hose outdoors or in a bucket.
  • The next step will be to identify the gas supply line and the valve that controls the gas supply.
  • To turn off the gas supply, turn the lever in a perpendicular direction or the knob in a clockwise direction.
  • Find the relief valve, which is often located at or at the top of the water heater.

Remove your finger from the valve and air will be permitted to enter the tank. That’s all there is to it! You are now prepared to undertake maintenance in a safe manner. On YouTube, there is a video showing how to turn off a water heater.

When Not Using a Hot Water Heater Is it Best to Turn it Off Completely?

The cost of heating water accounts for around 12 percent of the total energy consumed by the average home. Storage tank heaters that are used in the traditional manner continually keep a tank of water at a predetermined temperature. As the water in the tank cools, it is continually warmed, even during periods of time when there is no need for hot water in the tank. Homeowners frequently ask whether turning off the water heater during those hours and simply warming the tank during peak demand will save them money on their energy bills.

On/Off Cycling

  1. The baseline amount of energy required to heat a cold tank of water up to 120 degrees in a single long heating cycle is less than the baseline amount of energy necessary to heat and maintain the temperature of the tank through a series of shorter on/off cycles. Furthermore, because heat loss through tank walls increases in direct proportion to the temperature of the water, the energy consumption of water heaters is somewhat greater when the water in the tank is kept hot all of the time. During lengthy periods of time when there will be no need for hot water in the home, it is possible to save a little amount of energy by turning off the water heater completely and allowing the water in the tank to cool.

Timed Operation

  1. The energy savings from turning off an electric heater during idle periods are larger than the savings from turning off a gas-fired heater. The use of timers to automatically turn an electric heater off for extended periods of time, such as overnight or daytime hours when the house is vacant, and then back on at certain intervals is readily accessible and simple to install.

SHOULD YOU TURN OFF YOUR WATER HEATER OR LEAVE IT ON?

The majority of individuals turn off various electrical appliances on a regular basis in order to save money. One query that we frequently receive from consumers is if their water heaters should be switched off as well. When it comes to energy efficiency, we at wiremasters electric want to see our clients save money on their power bills while also reducing their carbon footprint. As a result, we recommend that water heaters be turned off on a regular basis.

Why turn off your water heater?

It is possible to save money each month on your energy bill by turning off your water heater, as well as a variety of other electrical equipment. Even though the water heater is well-insulated, a little amount of heat escapes when the water heater is switched on. Typically, this loss of energy accounts for around 10% of your total energy expense. If you turned off your water heater, you might save 10 percent on your energy bill and prevent further energy loss as well.

How to turn off your water heater

The majority of water heaters are equipped with an on/off disconnect button that allows you to turn the appliance off on your own. You should turn it on a half hour before you need it, and then off immediately before you start using the hot water, if you want to use it for anything. Installing a timer on your water heater is yet another option for turning off your water heater. This spares you from having to manually turn on and off your water heater; nevertheless, the expense of installing a timer might be prohibitively expensive.

It is not recommended to wait until you have finished using the hot water before turning off the heater since it will begin heating up the new water in the tank, resulting in a tank full of hot water and heat escaping from the tank.

Should I Turn Off the Water Heater if the Water Is Off?

When you turn off your water line, cold water will cease flowing into your house completely, and if your water heater has a tank, the tank will stop replenishing with cold water when the water line is turned off. In the event that your water is turned off for an extended length of time and you use a lot of hot water, you run the danger of sustaining catastrophic harm. If your water is shut off for a lengthy period of time, such as during a vacation, you should switch off your water heater. If you have a tank-type or hybrid water heater, you should not turn off your water heater.

Various types of water heaters will be discussed in this article, as well as how they are connected to a water line and what to do if you need to shut off your water or encounter a cutoff for whatever reason.

How Water Heaters Work

Even in the summers, the water that enters your home through a water line and the related pipes is normally chilly or cool to the touch. In order for you to have warm water in your house, the water must first be heated before it is delivered through the plumbing system. Water heaters are often placed in the basement of a house and require either a gas or an electric heating unit to operate. There are four fundamental types, each of which performs the same purpose in a slightly different way than the other three types.

Tank-Type Heaters

Tank-type water heaters are the most common form of water heater on the market. Essentially, it is comprised of an insulated tank filled with water that is placed above or beside a gas or electric heating device to provide warmth. The cold water enters the tank from the bottom and rises when a gas flame or an electric element warms the water to the surface. A pressure relief valve prevents the heater from being overly pressured if the pressure rises too high. When a hot water appliance or faucet is required, the water tank pumps hot water out of the tank through the top of the tank and replaces it with new, cold water at the bottom of the tank, as shown.

Tank-type heaters also use energy continually in order to keep the water in the tank warm even when it is not needed, making them less efficient than certain other heating methods.

Tankless Water Heaters

Because they do not store water, tankless water heaters are significantly smaller than traditional tank-type heaters. It instead waits for a hot-water tap or appliance to demand warm water before activating an electric element or gas burner and drawing cold water directly over the heating mechanism and to where it is required. Despite the fact that tankless water heaters last far longer and provide an unending supply of hot water, they are significantly more expensive to acquire, install, and maintain than tank-type water heaters.

Hybrid Water Heaters

However, they consume more energy than a tankless water heater, which is the most energy-efficient option available. On the surface, the hybrid works by storing water in a tank coupled to an air compressor, which uses air temperature to catch and transmit heat to cold water instead of a gas flame or electrical parts.

Point-of-Use Heaters

These tiny and compact heaters are typically used in conjunction with the main water heater to provide hot water on demand. Point-of-use heaters are often put at fixtures that are far away from the main heater in order to prevent the need to run the water and wait for the water to warm up before using it.

These electrically driven machines heat the water instantly, so removing the need for a waiting period. Point-of-use water heaters often last a long time and can be installed quickly and simply, but they cannot be used to replace a home’s primary water heater due to their smaller size.

How the Home Water Line Works

You may find the location of your water main by looking for a 12″ to 112″ pipeline that runs near your water meter if your home is linked to the city’s water system. The presence of an emergency shutdown valve, which would cut off all water flowing into your plumbing system, is also possible, although it is not guaranteed. It is possible that your home is connected to a water well, in which case your system may appear somewhat different, but the function will be the same. The water that enters your house through the main water line has been pressured, allowing it to move through your pipes against gravity, saving you time and money.

If you do experience a burst pipe, it’s critical to utilize your emergency stop valve to prevent extensive flooding from occurring.

The Water Line and the Water Heater

It is important to note that the water entering your home is chilled and passes through cold water pipes. An inlet line from the water heater is connected to one of these pipes. Your water heater is also connected to a hot water line, via which water is sent to various appliances and faucets. Whenever water is required, it is fed into and out of the heater.

What Happens to the Water Heater When Your Water Is Turned Off?

Cold water ceases flowing into your plumbing system from the outside when you turn off your water, which means that your tank-type or hybrid heater will no longer be able to replenish with more water. If the water is turned off for a lengthy period of time and the tank is completely depleted, it is necessary to turn off the water heater to prevent damage to the tank and other components. Unless your water heater is nearly full or completely full, you should not be required to turn it off during a short-term water disconnection.

When to Turn Off Your Water Heater

Cold water ceases flowing into your plumbing system from the outside when you turn off your water, which means that your tank-type or hybrid heater will no longer be able to replenish with water. The water heater must be turned off if the water is turned off for a long length of time and the tank has been completely emptied in order to prevent any harm from occurring. You should not have to switch off your water heater if it is fully or almost fully charged during a short-term water shutdown, though.

  • The following factors contribute to high pressure and high temperature: improper drainage, old age, and damaged tank.

In order to save money by not operating the water heater while it is not in use, it is preferable to lower the temperature of the water heater rather than totally shutting off the system. Turning back on a water heater may be a challenging task, and you may find yourself without hot water for a longer period of time than you’d prefer.

You should proceed with caution and ensure that you are familiar with the components of your water heater before making any alterations if you decide to turn off your water heater. The following are the components of a water heater:

  • The shutdown valve, which is normally positioned outside and above the water heater, is responsible for stopping the flow of cold water into the device. The drain valve is often found towards the bottom of the tank and is responsible for emptying the water and sediment from the tank. Using a pressure release valve, you can ensure that the pressure inside the tank stays below acceptable limits. If you are concerned about an empty tank following a water shutdown, the heating mechanism, which may be either gas or electric, is the most critical portion of the tank to switch off.

Conclusion

In the majority of circumstances, you will not need to turn off your water heater if the water is turned off. The water heater must be turned off only in the unusual event that you have had your water cut off for a lengthy period of time and have used up all of the water in the tank of your water heater. Call a skilled plumber whenever you’re in doubt.

Should You Turn Off Your Water Heater When on Vacation?

It is not always necessary to turn off your water heater when the water is switched off. The water heater must be turned off only in the unusual event that you have had your water cut off for a lengthy period of time and have used up all of the water in the tank of the water heater. Call a professional plumber whenever you’re unsure.

Turning Off Your Water Heater Does Not Provide Significant Energy Savings

Turning off your water heater for a typical week-long trip will not result in any major energy savings, according to the EPA. As a matter of fact, depending on the type and model of your unit, you’re likely to experience savings of only a few cents each day at most. Turning off your water heater isn’t required unless you’re planning to be away from home for a month or more.

Shutting Off Your Water Heater Can Cause Problems

If you leave your water heater turned off while on vacation, you may find yourself with water heater troubles when you return. The most obvious problem is that you won’t have access to hot water during your stay. For those post-travel showers, it might take up to an hour for any hot water to become accessible, and that’s only if you’re able to turn your water heater back on again. Depending on how old your unit is, you may have some trouble turning it back on after it has been turned off for a period of many days.

Should You Turn Off Your Water Heater When Not in Use?

As an alternative to shutting off your water heater before you leave, set it to “vacation” mode before you go. If your unit does not have a vacation setting, you can manually adjust the temperature to anywhere between 50 and 70 degrees Fahrenheit. You may still save a few dollars while guaranteeing that your water heater is still operational when you return from your vacation, despite the fact that the energy savings will be minor. If you are going on a lengthy vacation and will be emptying and turning off your water heater before you go, be sure to read the instructions that came with your water heater before you depart.

Does Shutting Off Your Water Affect Your Water Heater?

There are several circumstances in which you may need to switch off the main water supply to your home, particularly if you are experiencing a plumbing problem. Some people are puzzled as to how shutting off the water could possible have an impact on their water heater. It is necessary to cut off the water before performing some tasks, such as fixing a leak or replacing a water heater, in order to avoid a flood in specific scenarios. No need to be concerned about how long it will take to repair a water heater because our HVAC professionals have a wealth of knowledge and expertise in the field.

With decades of combined expertise in the plumbing industry, our professionals are ready at any time of day or night to assist you with any plumbing situation you may be experiencing.

When to Turn the Water Heater Off

Every day, customers ask us, “Should I switch off my water heater if I’ve already shut off the main water supply?” There is no definitive solution to this question. The same way that there are a number of circumstances in which you would be required to switch off your main water supply, there are a variety of conditions in which we might urge you to turn off your water heater, too. It is extremely necessary to turn off your water heater in the following two conditions :

  • When your water tank is empty and you know you will be away from home for an extended period of time, such as when you are going on vacation
  • In the extremely uncommon event that you lose pressure on the cold-water side of your faucet

The following situations may arise: When your water tank is empty, and you know you will be away from home for an extended period of time, such as when you go on vacation; In the extremely improbable event that your cold-water pressure is lost;

Why a Water Heater May Leak

When your water tank is empty and you know you will be away from home for an extended amount of time, such as when you are going on vacation; In the extremely improbable event that you lose pressure on the cold-water side of the house;

  • Drain valves or fittings that are not in proper working order
  • Storage tank that has been damaged
  • There is excessive pressure as a result of an excessively high temperature or an excessively high pressure of the external water entering the tank. a lack of sufficient drainage
  • Age

I think it’s fantastic that you were able to fix the problem on your own. However, you may still be apprehensive about attempting to repair it yourself. Not to worry — there isn’t a plumbing issue that Ambient Edge cannot handle!

Lowering Water Heating Bills

Another reason some individuals choose to turn off their water heater is to save money between usage of the water heater. This, on the other hand, has no effect on your ability to save money. In fact, you may create yourself additional issues by doing so, such as returning home to find that you have no hot water and having difficulty turning the unit back on.

The “VAC” Option

To save money on your water heating expenses, try reducing the temperature on your water heater down or putting it into “vacation” mode if your water heater is modern and has this option. You’ll be able to tell whether you have this function since the thermostat is normally labelled with the letter “VAC.” When you use the VAC option, the temperature of the water is reduced to 50 degrees Fahrenheit, which allows your water heater to operate more efficiently. (Normally, the water heater maintains a consistent temperature of between 120 and 130 degrees Fahrenheit in the water.) A lower temperature, on the other hand, keeps your heater operating in a more steady condition, preventing it from experiencing overload when you turn it back on.

If you place a newer model in vacation mode, the efficiency will be the same as if you used an older model. Please contact us if you want HVAC Service in Las Vegas NV.

EMERGENCY WATER HEATER SHUTDOWN PROCEDURES

The query “How do I switch off my water heater?” is one of the most often asked queries we receive from clients at Horizon Services. The ability to accomplish this task is something that every homeowner should have. In the event that your water heater is overheating, making strange noises, or otherwise acting abnormally, it is EXTREMELY IMPORTANT that you do not allow it to continue to operate; the longer the problem is allowed to persist, the more likely it is that you will experience leakage, flooding, or worse.

Do-it- Anyone who does their own water heater maintenance will want to empty the water from their tank every three months to minimize sediment buildup, enhance performance, and reduce energy use.

No matter whether you have a gas water heater or an electric water heater, these procedures should be followed each time you need to turn off your water heater.

Water Heater Shutdown Instructions:

  • If you have a gas heater, you can turn it off by turning a dial on the top of the thermostat from ON to OFF. Electric: Turn off the water heater’s circuit breaker by pressing the button on the circuit breaker.
  1. DISCONNECT THE WATER SUPPLY. Turn the handle on the water valve in a clockwise direction until it comes to a complete halt. Switch off the main water valve for the entire home
  2. Then drain the water heater. If the water doesn’t stop, turn off the water heater. Connect a hose to the drain valve, which is located at the bottom of the tank. The other end of the hose should be routed to a lower location where you may safely discharge the rusty, hot water without causing any damage. Raise the temperature of a hot water faucet in the house in order to allow air to enter the tank
  3. OPEN THE RELIEF VALVE Flip the handle so that it is pointing straight out or up from the table. (USE CAUTION: scalding hot water is present)

Shutting Down an Electric Water Heater

This article is largely concerned with the process of turning off an electric water heater. Water tank interior parts may be damaged if the required procedures are not followed. There are just a few steps to complete, and they are all straightforward. Gas water heaters and electric water heaters are the most common types of water heaters found in most households. See the section below for information on how to determine what type of water heater you have installed. Propane would be included in the definition of gas for the purposes of this debate.

When it comes to shutting off an electric hot water tank, there are two processes involved.

Do not undertake any repairs on an electric hot water heater without first shutting down the electricity supply.

Even the simple act of removing the inspection covers might be hazardous. Not sure whether this is the source of your issue? If you’re looking for a comprehensive list of water heater topics, check out the articles ‘Electric Water Heater Troubleshooting’ and ‘Troubleshooting Gas Water Heaters.”

Identifying Water Heater Types

The simplest and possibly most obvious way to tell if a water heater is electric is to look for an electrical line that enters the tank from the top. This cable might be made of metal conduit, flexible metal cable, or even a romex cable with a plastic sheath. The majority of the time, this cable will enter the unit at the top, however it is conceivable that it could enter the unit by the side. There are a variety of gas water heaters available with electrical connections, so this does not rule out the possibility of purchasing one of them.

These are more costly versions that are also less prevalent.

Lack of a Vent

Electric hot water heaters do not have vents, unlike gas or propane models. The use of vents on gas water heaters is essential in order to eliminate hazardous gases. Electric water heaters do not emit any fumes, and as a result, they do not require a vent. Vents can be constructed of metal or plastic, and they are often installed in a chimney, a metal vent pipe, or through an outside wall. With an electric water heater, the only thing that can be found on its top is its water inlets and a power line.

Upper and Lower Access Panels

It is not possible to install vents on electric hot water heaters. It is necessary to have ventilation on gas water heaters in order to exhaust the harmful gases. The absence of a vent is due to the fact that electric water heaters do not emit fumes. Fabricated from metal or plastic, vents are often installed in a chimney, metal vent pipe, or an outside wall. With an electric water heater, the only thing that can be found on top of it is water inlets and a power wire. There will be NO VENT in the building.

No Gas Burner

Internal heating components are used in an electric hot water heater, which eliminates the need for a burner assembly. Typically, the burner component is located at the bottom of the hot water heater, making it easy to locate. Are you unsure about which kind you have? There are a few of distinguishing characteristics that make it simple to determine which type you are wearing. Electric water heaters are easy to spot because of their wiring that enters them via their tops (Figure 1). Aside from that, because they do not need any fuel to heat up, electric water heaters do not have any vents.

Your hot water heater’s heat exchanger might be made of metal or plastic, depending on its efficiency level.

No Gas Lines

In the case of an electric water heater, there will be no gas line connected to the water heater. Gas lines are massive, heavy pipes with a lot of large fittings attached to them.

The term “black pipe” refers to the fact that it is black and greasy when it is constructed. The gas line links to the gas valve, which is located at the bottom of the water tank. On an electric water heater, you will not notice any of these features.

How To Identify a Gas Hot Water Heater

The presence of a gas valve and burner assembly at the bottom of the water heater is a telltale indicator that it is a gas water heater. A strong metal gas pip will be fitted to the gas valve to ensure that it operates properly. In the bottom of the unit, there will be a burner assembly, which will be covered by a detachable plate. In order to protect the bottom gas line and thermocouple connector, this plate will protrude from the wall. After the outer cover plate has been removed, it is generally easy to see a pilot light via a window in most cases.

Fume Vent at Top

Natural (or propane) gas hot water heaters heat water by burning the gas that is supplied to them. When fossil fuels are used, they release hazardous gases into the atmosphere. As a result, a gas hot water heater will always include some sort of venting system. The efficiency of the hot water heater determines the sort of vent that should be used. Higher efficiency units will employ a plastic pipe to vent through an exterior wall, rather than through the ceiling. A lower-efficiency unit will be vented through a brick or metal fireplace.

Gas Lines

Natural (or propane) gas hot water heaters heat water by burning the gas. Carbon dioxide is released during the combustion of fossil fuel. As a result, a gas hot water heater will always have some sort of venting system. According to the efficiency of the hot water heater, the type of vent to use should be chosen. More energy-efficient units will vent via an outer wall, which will be made of plastic. Units with lower energy efficiency will vent into a masonry or metal chimney. Venting apparatuses will not be included with electric water heaters.

Shutting Down an Electric Water Heater

When it comes to correctly turning down an electric hot water heater, there are five stages to follow: (1) Turn off the electricity to the water heater. (2) Turn off the gas to the water heater. While you are working on the water heater, make sure that no one switches the power back on by putting a breaker tag on it. (3) Reduce the temperature of the water within the tank. (4) Turn off the water supply to the hot water tank from the cold. (5) Turn on a hot water faucet somewhere in the home (ideally on the second floor).

Step One – Turning Off a Water Heater Breaker

The majority of water heaters will be equipped with a two-pole circuit breaker. This breaker should be labeled on your circuit breaker panel. It will most likely be between 30 and 50 amps in most cases. Disconnect the electricity at the breaker panel. Don’t be happy with simply turning off the power. If you have lock out lugs for your breakers, you may use one of them to secure the breaker. It’s also possible to tape it up and label the tape so that no one can switch it back on again later on.

Inform them that they are not permitted to touch the service panel.

When you open the covers, check to see that nothing is hot within them using a voltage tester (a non-contact voltage tester would suffice).

When replacing a hot water heater element, it is not worth the risk of being shocked or injured. WARNING! Check to see that the power is turned off! Work on Electrical Devices ONLY AFTER You Have Completed This Checklist!

Step Two – Tag the Breaker

When working in large buildings or on construction projects, safety regulations require that a ‘lock out – tag out’ method be followed whenever something that might cause bodily injury is present. In order to notify everyone who has access to the panel that a circuit is being worked on, electrical circuits must be closed off and marked with a tag while they are being worked on. In a house, these stringent rules are not in place to protect the family. A person who is concerned about their safety, on the other hand, will want to take comparable safeguards.

  1. OSHA provides rules for this, but every scenario is unique, and it is the duty of the person or contractor who is performing the work to ensure that safety procedures are observed and observed properly.
  2. Prevent the breaker from being accidentally activated by taking the necessary precautions.
  3. Place a piece of tape over the breaker that has been switched off at the panel.
  4. This will prevent someone from mistakenly re-enabling the power while you are working on the problem.

Step Three – Cooling the Hot Water

When performing numerous tank repairs, it is best practice to allow for cooling of the water before beginning the repair. When the electricity is turned off, the water will no longer be heated, even if the temperature dips below freezing. Use one of the sinks’ hot faucets to reduce the temperature of the water. Do not add any cold water to the faucet; instead, let it run at its maximum temperature. Allow the water to run until it feels lukewarm to the touch. If the water pouring out of the tank is warm to the touch, it will be safe to operate on the tank in this condition.

So let the tank to sit for about an hour before attempting to use it for anything that requires hot water, such as a shower or doing laundry.

Step Four – Shutting Off the Water

It is not necessary to have a shut off valve on the hot water output side of a correctly fitted hot water tank. This will prevent the tank from accumulating an excessive amount of internal pressure over time. When working on your hot water tank, all that is required is the interruption of the cold water supply. It will be necessary to establish which of the two valves above your water heater is the cold supply line if you have two valves. When looking at the tank from the front, the valve on the right should be the one to use.

When you run hot water through the pipes, you can feel the pipes.

After you’ve ran hot water through it, the hot water intake will be warm to the touch.

You can identify which one is the hot and which one is the cold pipe by feeling the pipes. Mark the cold water valve with a permanent marker so you will know which one to turn off. Wait until the water within the tank has cooled down before turning off the water supply to the tank.

Step Five – Draining a Hot Water Tank

There should be no shut-off valve on the hot water output side of a hot water tank that has been correctly installed. This will prevent the tank from accumulating an excessive amount of internal pressure inside it. When working on your hot water tank, just turning off the cold water supply is sufficient. It will be necessary to establish which of two valves above your water heater is the cold supply line if you have two valves. When looking at the tank from the front, the valve on the right side should be the one you want.

  • It is possible to feel the pipes while hot water is running.
  • After you’ve ran hot water through it, the hot water intake will be warm.
  • To know which pipe is hot and which is cold, simply feel the pipes.
  • Wait until the water within the tank has cooled down before turning off the water supply to the house.

Where To Next?

After you have done your repairs, you will need to restore the functionality of your water heater. Instructions may be found in the page titled “Starting a Hot Water Heater.” The procedures are identical to those for turning off a water heater; the only difference is that you must follow them in the proper order.

How To Turn Off a Hot Water Heater

It is the purpose of this article to explain how to turn off a gas hot water heater. Water tank interior parts may be damaged if the required procedures are not followed. There are just a few steps to complete, and they are all straightforward. Gas water heaters and electric water heaters are the most common types of water heaters found in most households. Propane would be included in the definition of gas for the purposes of this debate. If you have an electric hot water heater, go to the article ‘How to Shut Down an Electric Hot Water Heater’ for specific instructions on how to shut down this type of appliance.

See the section on “troubleshooting gas water heaters” for information on all forms of gas water heater issues.

Identifying Water Heater Types

Are you unsure about which kind you have? There are a few of distinguishing characteristics that make it simple to determine which type you are wearing. Electric water heaters are easy to spot because of their wiring that enters them via their tops (Figure 1). Aside from that, because they do not need any fuel to heat up, electric water heaters do not have any vents.

The vent at the top of a gas water heater is a telltale sign that it is working. Your hot water heater’s heat exchanger might be made of metal or plastic, depending on its efficiency level. A gas water heater is also equipped with a gas line, which connects to the unit around the bottom of the unit.

How To Identify a Gas Hot Water Heater

Are you unsure of the type of plant you own? There are a few distinguishing characteristics that make it simple to determine which type you are wearing. Electric water heaters are easy to spot because of their wire that enters them via their top. Additionally, because they do not need any fuel to heat up, electric water heaters do not have vents. Identifying characteristics of a gas water heater include a vent located at the top. Depending on how efficient your hot water heater is, this might be made of metal or plastic.

Fume Vent at Top

Natural (or propane) gas hot water heaters heat water by burning the gas that is supplied to them. When fossil fuels are used, they release hazardous gases into the atmosphere. As a result, a gas hot water heater will always include some sort of venting system. The efficiency of the hot water heater determines the sort of vent that should be used. Higher efficiency units will employ a plastic pipe to vent through an exterior wall, rather than through the ceiling. A lower-efficiency unit will be vented through a brick or metal fireplace.

Gas Lines

Of course, it comes to reason that a gas hot water heater would run on natural or propane gas to heat the water it produces. This sort of gas is a low-pressure fuel that necessitates the use of a massive pipe system to transport it. The pipe that will be linked to the burner assembly stated above will be required. When you look at the water heater, you will be able to see this pipe clearly. It will be joined to the gas valve located at the bottom of the unit and will typically be connected on the left side of the unit when facing the water heating unit.

Lack of a Vent

Electric hot water heaters do not have vents, unlike gas or propane models. The use of vents on gas water heaters is essential in order to eliminate hazardous gases. Electric water heaters do not emit any fumes, and as a result, they do not require a vent. Vents can be constructed of metal or plastic, and they are often installed in a chimney, a metal vent pipe, or through an outside wall. With an electric water heater, the only thing that can be found on its top is its water inlets and a power line.

Upper and Lower Access Panels

Electric hot water heaters heat water by circulating it via heating elements. The majority of them are composed of two elements: an upper and a lower component. The heating components are hidden behind access panels on the side of the water heater for easy access. It is possible that the panels will be spaced differently, but typically one will be towards the bottom of the water heater and the other can be anywhere from the middle of it to the top. The panels may be a different color from the rest of the water heater housing or the same color as the rest of the water heater housing.

A gas water heater will simply have a gas valve and a burner access panel at the bottom of the water tank, and will not have any other features. There will be no access panels on the upper levels of the dwelling.

No Gas Burner

Internal heating components are used in an electric hot water heater, which eliminates the need for a burner assembly. Typically, the burner component is located at the bottom of the hot water heater, making it easy to locate. Are you unsure about which kind you have? There are a few of distinguishing characteristics that make it simple to determine which type you are wearing. Electric water heaters are easy to spot because of their wiring that enters them via their tops (Figure 1). Aside from that, because they do not need any fuel to heat up, electric water heaters do not have any vents.

Your hot water heater’s heat exchanger might be made of metal or plastic, depending on its efficiency level.

No Gas Lines

In the case of an electric water heater, there will be no gas line connected to the water heater. Gas lines are massive, heavy pipes with a lot of large fittings attached to them. The term “black pipe” refers to the fact that it is black and greasy when it is constructed. The gas line links to the gas valve, which is located at the bottom of the water tank. On an electric water heater, you will not notice any of these features.

Shutting Down and Gas Hot Water Heater

When it comes to correctly turning down a gas hot water heater, there are four stages to follow: (1) To operate on water pipes or drain the tank, turn the gas valve control to the pilot position. (2) If you need to perform any additional repair on the hot water heater, turn the gas off entirely. (3) Reduce the temperature of the water within the tank. (4) Turn off the water supply to the hot water tank from the cold. (5) Turn on a hot water faucet somewhere in the home (ideally on the second floor).

Step One – Setting a Gas Valve On ‘Pilot’

The gas valve for your water heater is placed near the bottom of your water heater, right above the burner chamber, and is easily accessible. There is a gas valve on the top of the tank that has several settings. Off, Pilot, and On are the three most important settings to remember. When the dial is set to ‘Pilot,’ the gas to the burner will be turned off without the pilot light being extinguished. The convenience of not having to re-light the pilot when you are finished may be a significant time savings.

It is appropriate for use while draining the tank or doing maintenance on the water pipes in the home.

Step Two – Turning the Gas OFF

Working on your gas hot water heater should always be done in the safest manner possible. Leaking gas has the potential to explode and is extremely dangerous. To begin, turn the dial on the gas valve to the ‘OFF’ position. By just turning off the gas valve, you are not truly shutting off the gas.

Next to the water heater is a ball valve that is part of the gas piping system. The handle of this valve should be perpendicular to the pipe once it has been rotated 90 degrees. After shutting off the gas valve fully, the gas is no longer present, making it safe to operate around the water heater.

Step Three – Cool Down the Water

This is a critical first step. Water that comes right out of a gas hot water tank can be extremely hot and scald or burn you if you are not careful. Run a substantial volume of hot water through one of the fixtures until the water is only slightly warm to the touch. Do not combine it with cold water; instead, run it just with hot water. It is expected that the cold water flowing into the tank will dilute the hot water and lower its temperature. To work on the water heater, it is best to wait until the water has completely cooled down.

Step Four – Shut Off the Cold Water Supply

It is not necessary to turn off the water if you have not switched off the gas supply to your gas hot water heater. If the water within the water heater continues to heat after the water has been turned off, the heater will build up an excessive amount of pressure. You can switch off the cold water supply if you are certain that the water has been turned off.

Step Five – Open a Hot Water Faucet

The opening of a faucet will avoid the development of an air lock in the water heater. Any attempts to drain the water tank will be unsuccessful if a faucet is not left open to allow for the passage of air. It should be okay to begin working on your hot water tank at this point.

Step Five – Draining a Hot Water Tank

The majority of repairs on a gas hot water tank may be completed without the need to drain the tank. There are, however, a few notable outliers that must be taken into consideration. The removal or replacement of a gas valve will need the draining of the tank. This section of the tank is threaded directly into the bottom section of the tank. Another task that necessitates the use of an empty tank is the removal of silt. A effective preventative maintenance routine includes flushing away water heater sediment on a yearly or semi-annual basis.

Where To Next?

After you have done your repairs, you will need to restore the functionality of your water heater. Instructions may be found in the page titled “Starting a Hot Water Heater.” The procedures are identical to those for turning off a water heater; the only difference is that you must follow them in the proper order.

5 Simple Steps to Turn Off Water Heater

Gas or water leaks are some of the things that might cause the most anxiety in a person. However, if you know how to switch off a water heater, you won’t have to worry about this all of the time. When you hear your digital alarm go off, now is not the moment to worry or do anything stupid. Even before you hire a plumber, you must switch off all of the utilities to prevent a gas or water leak from spreading.

How to Turn Off Water Heater

Heat exhaustion, unusual noises, and other warning signals indicate that you are in danger, and you must take action immediately. So, if you want to learn how to switch off a water heater, then follow these simple steps: 1.

Step 1. Disconnect from the Power Source

The first step is to locate your water heater’s power source and disconnect it from the grid.

If there is an electric unit, make certain that the circuit breaker is turned off before proceeding. When dealing with the gas unit, look for the dial that is next to the thermostat and turn it in the other way.

Step 2. Turn the Water Off

This procedure should not be performed until you are certain that the electricity connection to the water heater has been switched off fully. If you have an electric tankless water heater or a gas tankless water heater, they both have numerous types of handles to choose from. Some handles are circular, and all that is required to switch them off is a little rotation to the right of the handle. With this operation, you allow cold water to flow into the sink and tubs, and hot water will no longer be available to those fixtures.

Navigate to a valve near the meter and flip it in the other way by removing the box and turning it back.

Step 3. Carefully Drain the Water in the Tank

Wait until you are certain that the electricity connection to your water heater has been completely switched off before proceeding. Depending on whether it is an electric tankless water heater or a propane tankless water heater, they will have a variety of handles. Some handles are circular, and all that is required to turn them off is a slight rotation to the right of where they are located. As a result of this action, cold water will be able to flow into the sink and baths, and hot water will not be available.

Navigate to a valve near the meter and turn it in the other way by removing the box and turning it again.

Step 4. Label Your Circuit Breaker

It is possible that the content of your circuit breaker is complex and ambiguous. This will need the use of labels to ensure that you are aware of the original position of each component. In the event of an emergency, and you are forced to turn off the power totally, those labels will be quite useful. If you have a circuit breaker that has already been labeled, carefully inspect each component to discover its purpose. You don’t want somebody to assume you shut off the electricity when you actually did not.

Step 5. Practice Shutting Off Water Heater

When their heater leaks or their alarm goes off, the majority of individuals worry and get befuddled. The only way to avoid this confusion is to be aware of how to switch off the water heater in advance of when it is needed. Maintaining the practice of emptying your water heater every six months will help you become more familiar with the procedure. Make a practice of turning on and off the hot water heater supply that runs throughout the entire house. Become adept at opening the valve carefully, since twisting it too rapidly might exacerbate the situation.

This understanding is also applicable when it comes to cutting off the water supply to all of the appliances in your home.

A little frequent practice can help you to overcome the feelings of terror that you may encounter in an emergency. When your water heater is heating, you will not want to make the situation worse by not knowing how to switch it off when it is heating.

Regularly emptying your water heater every six months can help you get more familiar with the process. Get comfortable with the process of turning on and off the hot water heater supply that runs throughout the entire home. Become adept at opening the valve carefully, since twisting it too rapidly might exacerbate the problem.

In addition, this information is useful when shutting down all of the water-using equipment in your home.

When your water heater is heating, you will not want to make matters worse by not knowing how to turn it off.

Step 1: Turn Off the Water Heater Valve

You will see a red or black button on the front of the tank if you look closely. These buttons are sometimes buried under insulating materials, and you must remove the insulating material in order to show the button. The switch should be moved or turned from the “on” position to the “off” position. When you turn off the heater, the pilot light will cease operating and the burner will stop heating. Remove the heat shield and inspect the inside for evidence of heat or flames before replacing it.

Step 2: Turn Off the Line that Supplies Gas

If you wish to go outside and hear the heater hissing, turn off the gas line valve before you leave the house. Simply go to the heater and turn off the gas valve that is situated on the gas line near the heater. The lever should be perpendicular to the gas line when it is fully extended. If you can’t locate any valves, follow the gas line until you come to a handle that functions as a switch for the light. Gas line valves are usually straightforward to find, and you won’t have to spend much time looking for them.

Step 3: Shut Down the Water Heater

If you’re leaving home during winter, ensure you drain the water in the tank so that it doesn’t get frozen. Turn off the heater and wait for 12 hours to enable the water cool down and to prevent becoming scalded. To dump your tank, make sure you: Make sure you have a bucket underneath the pressure release valve so that the water flows directly into the bucket. Open the relief valve to enable the steam to escape, and then gently release the lever to close the valve completely. Connect a hose to the drain valve, which is situated near the bottom of the tank.

In most cases, the draining region should be located at a higher elevation than the water tank’s location.

Pouring water out of the faucets requires turning off the cold water valve and turning on the hot water taps.

After that, close all of the faucets in the home that are now open.

Alternatively, if the water does not drain, it is possible that mineral deposits have accumulated in the drainage channels. Shut off the valve and then pull off the hose to clean off all deposits. Reattach the hose and turn on the valve one more to complete the process.

How to Turn Off an Electric Water Heater

The following five actions are essential in turning down your electric water heater. Follow the instructions and you will discover how to turn off your water heater in your residence.

Step 1: Turn Off the Breaker

Locating the two-pole circuit breaker is the first step in figuring out how to switch off an electric water heater. It has a current of around 30 to 50 amps and is generally labeled. Even if you have turned off the electric water heater, it is always a good idea to cut off the electricity at the breaker panel. If the breaker is equipped with lock-out lugs, secure them to the breaker. If you are concerned that you will make a mistake, identify the breaker with paper tape to prevent this from happening.

They should refrain from getting close to the service panel or the water heater until you are finished with them.

When replacing the water heater element, it is dangerous to expose yourself to electric shock or high temperatures.

Step 2: Put a Tag on the Breaker

Safety regulations require that you label everything you are working on in order to prevent anyone from being injured. When working with electricity, it’s best to keep the area closed off to prevent prospective victims from entering the area. Mark the location and the equipment to serve as a warning to anyone who might unintentionally walk too close to the site. When it comes to the home, simply turning off the breaker isn’t adequate because everyone is exposed to the same hazard. The use of identification and restrictions to notify family members about potential threats would be extremely beneficial.

Don’t take the concept of safety lightly because even a single electrocution can result in death.

Putting paper tape on the breaker and labeling it “Do Not Touch” is another technique to ensure safety.

Step 3: Cool Off the Water

Before you begin any repairs, you will need to let the water in the tank to cool down. It is advisable to switch off the heater in order to prevent the water from being overheated. Set aside some time for the water to gently and gradually cool on its own. You should avoid attempting to chill the water by adding cold water to the container. Simply turn on a faucet in your home and let it to flow for an extended period of time. After some time, the water should feel lukewarm, which indicates that it is okay to begin your repairs.

Once the repair is complete, switch on the water heater and allow the water to heat up as normal for around 15 minutes. Before using hot water for showering, laundry, or dishwashing anywhere in the house, wait one hour.

Step 4: Turning Water Off

Water tanks should always be equipped with a shut-off valve located on the outlet outside the home’s perimeter. The tank’s placement prevents it from accumulating an excessive amount of internal pressure. When working on the hot water tank, make sure to turn off the cold water supply. If your tank has two valves, locate the one that allows cold water to enter and shut it off completely. When facing the tank, the valve is normally on your right as you stand facing it. Normally, two valves should not be found on a single supply line, therefore use caution when doing this task.

The cold line is used for cold water, while the hot pipe is used for hot water, as the name implies.

The hot water supply line is the one that vibrates as the water flows out of the faucet.

Step 5: Drain the Hot Water Tank

As you learn more about how to switch off the hot water heater supply, you’ll come across a few interesting facts. It is possible to carry out various chores without having to empty the water tank. While changing or testing the thermostat or monitoring the power supply unit, you can leave the tank at its maximum capacity of 80%. Draining the water is required before doing activities such as removing or replacing an element or flushing sediments. The accumulation of deposits in the bottom part of the tank might have an impact on the heating of the water in that section.
