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
Check the bottom of the tank to see if there is a place where you can attach a hose to drain the water. Insert the hose’s other end into a floor drain or a bathtub until all of the hot water has been drained. To find out if there is any special advice concerning safety when draining water, carefully read the product handbook. The first step in figuring out how to switch off a hot water heater is to cut off both the electricity and the water supply. Once this is completed, you will be able to reduce any possible risk that leaks or a faulty propane gas water heater may provide.
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.
How to Turn Off a Gas Water Heater
If your home is equipped with a tankless gas water heater, you must be familiar with how to turn off a Gas water heater. To have it done correctly, follow these simple steps.
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 going to be away from home during the winter, make sure you drain the water from the tank to prevent it from freezing. Turn off the water heater and leave it off for 12 hours to enable the water to cool and prevent scalding from occurring. You drain your tank, be sure to do the following: 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.
- Pull the hose to the specific location where you want the water to drain from.
- You should drain the water into your garden if you have one if you have a home with a garden.
- Allow for complete drainage of the water by keeping the drain valve open until the water is completely gone.
- Alternatively, if the water does not drain, it is possible that mineral deposits have accumulated in the drainage channels.
- Reattach the hose and turn on the valve one more to complete the process.
How to Turn Off an Electric Water Heater
When it comes to turning off your electric water heater, the five actions listed below are helpful.
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.
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.
Alternatively, you might choose to switch on a water faucet in your home. The hot water supply line is the one that vibrates as the water flows out of the faucet. Make a label for the cold line to serve as a reminder of which valve should be kept closed at all times.
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.
Clearly, shutting off water heaters of any sort has never been as simple as it is right now. The only prerequisite is that you know how to switch off your water heater. Yes, it is as straightforward as that. In the comments area, please tell whether your experience was similar or different from mine. Thanks for reading. We’ll be delighted to benefit from your first-hand knowledge. Continue to keep in mind the following summary of the processes outlined in this article:
- Turn off the water heater and the circuit breaker
- Turn off the lights and radio. Take care of your repairs before re-connecting the water.
Hot Water Heater Timer
How to Install a Hot Water Heater Timer for Electrical Hot Water Heaters is the subject of this Instructable. This piece of equipment may save you a significant amount of money and energy, allowing you to reduce your carbon imprint on our world. Since installing it, we have been able to reduce the amount of time we use our hot water heater by 16 hours each day. That equates to a 66 percent energy savings on a device that works practically continuously and consumes a lot of energy. The timer cost approximately $40, and then I had to spend another $15 on conduit and couplers, and then I had to run a few feet of wiring.
This timer will pay for itself in a short period of time, therefore we will compare the costs to see how long it will take.
Our breaker box was labeled with a whole set of labels, which turned out to have been applied at random!” Please have a look at my blog, which can be found here.
Step 1: Disconnections
Your next step will be to complete all of the disconnections, which will include: 1. Locate your house’s power box and turn off the breaker called ‘Hot Water Heater’; ours was labeled H/W Heater. 2. Locate your hot water heater and turn off the breaker labeled ‘Hot Water Heater’. 2. Remove the plate from the hot water heater and then the wire nuts from the hot water heater. 3. If you have conduit going to the wall, you must remove both the plate and the conduit from the wall.
Step 2: Installing the Conduit and Timer
The timer and conduit will be installed next, which will take some time. First, mark the location of an anchor and screw in an anchor until it is about 1/8 inch in diameter “a few centimeters short of being flush with the wall The box is at an angle because I did not permanently connect it to the wall, which is why it is at an angle; I will attach it later when everything has been measured and dry fitted together. 2. Connect the conduit to the wall cover plate that was originally installed. Because the wall mount was right above the box, I chose to attach the conduit to the side of the box; however, the placement of the conduit is entirely up to you depending on the location of the box.
3. Attach the conduit to the box and feed the wire through it, then trim the wire with around 3-4 inches of wire “excess in order to be able to connect to the terminals
Step 3: Wiring the Timer
In this phase, you will be connecting the wires to the Timer device. (Continue to follow the instructions in case they have been modified) 1. Pull the wires through the conduit and strip the wires back a half-inch. 2. 2. The wires from the hot water heater will be connected to the right terminals, while the wires from the home will be connected to the left terminals. 3. From left to right, Terminal1 is black from the house, Terminal2 is black from W/H, Terminal3 is white from the house, and Terminal4 is white from W/H.
Step 4: Finish Wiring and Close Up
The final stage in the installation process will be to complete all of the processes. Install the wire nuts back where they were when you first started. 2. Connect the ground wire to the ground screw using a grounding screwdriver. 3. Attach the cover plate to the right and left sides of the W/H.
Step 5: Setting the Timer
At this stage, you will set a timer and complete the task. 1. Place the transparent plastic cover over the wire and secure it in place. The time is adjusted by pulling out on the dial and rotating it to the appropriate time of day. DO NOT make any adjustments to the arm that is pointing down 90 degrees. Once you are completed, just screw on the corresponding adjusters at the appropriate times to complete your project.

It is necessary to have hot water on hand for showers and other household purposes. Have you ever considered that your water heater may be one of the factors contributing to your growing power bills? If your water heater is linked to a power source, it will continue to consume energy even when you are not utilizing hot water. In this situation, installing a water heater timer is a great alternative to consider. Many people are unsure of the benefits of placing a timer in their house. You may find that a timer is the best investment for your home if you do not require access to hot water on a continuous basis.
What is a water heater timer?
A water heater timer is a tiny, convenient electronic device that can be fitted to your existing water heater (gas or electric), allowing you to control when your water heater is turned on and off automatically according to a predetermined schedule. It provides you with greater control over the functioning of the water heater, allowing you to save money on your energy cost.
How much energy does a water heater use?
It is necessary to understand the energy consumption of a water heater in order to appreciate the significance of the timer. When a water heater is plugged in, it is constantly using electricity in order to keep the water hot for you. Water heating accounts for between 12 and 18 percent of total utility expenses in most houses. This statistic demonstrates that certain water heaters lose a large amount of energy while in standby mode, which is not uncommon. Using a timer can help you save up to 30% on your water heating expenditures each year by reducing standby energy loss and lowering your water heating costs.
How do water heater timers work?
You may configure the timer on your water heater to correspond to your daily hot water use. This indicates that, aside from the set period, the water heater will not be able to maintain hot water throughout the whole day. If, for example, you and your family require hot water for showers and other domestic tasks at 8:00 a.m., you may configure your timer to turn on your heater at 7:00 a.m. to meet your needs. Furthermore, if you will be gone from home for the remainder of the day, you may configure the timer to turn off the heater during that period.
- If your utility provider charges different rates for energy consumption during peak and non-peak hours, you will reap the most benefits from using a water heater timer.
- Each of them has a unique collection of features and configuration options.
- The amount of money you save by using a water heater timer will vary depending on the running cost of the heater, the kind of water heater, and the volume of hot water used by your household.
- It is an excellent method of increasing the efficiency with which water and energy are used.

Water Heater Timers: Types, Savings, & Installation Guide
A water heater timer is an electrical device that attaches to an electric water heater to regulate the temperature of the water. Hot water production and conservation may be controlled at certain times by setting precise “on” and “off” settings on the thermostat. You might be wondering right now if adding a water heater timer can help you save money on your energy expenses. Is it possible to save money by using a water heater timer? Yes, when used in conjunction with a water heater constructed prior to 1997, a water heater timer can help you save money.
- Modern water heaters are equipped with timers, which prohibit the water heater from heating the water when no hot water is required or while you are away from home for an extended length of time.
- We can assist you!
- Now that you’ve learned that using a water heater timer can help you save money, let’s take a closer look at this concept.
- Besides that, we will look at additional simple and practical strategies to save energy.
Types of Water Heater Timers
If all you’re looking for is a simple solution to save money when you’re away from home, such as while on vacation or traveling for business, a basic on/off water heater switch may be all you need. This is a basic On/Off switch that may be used on a water heater. It is made of plastic. Manual operation means that you must physically switch the water heater on or off whenever you require it. The following are examples of switches that may be put at the water heater to turn the water heater on and off:
- Installation of a 30amp wall switch near the water heater
- Installation of a 30amp indoor safety switch or service disconnect box
- Installation of an electrical breaker within the panelbox.
Water Heater Box Timers

Gas Water Heaters Timers
Many individuals are unaware that they may place a timer on a gas tank-style and tankless water heater, which can save money on energy costs. The majority of gas water heaters require some amount of power to function. A gas water heater (tank-style) burns gas on a continual basis through the burners and pilot light. Saving money and controlling expenditures are made possible with the use of timers, which give you back control over your water heater.
Is it Cheaper to Leave a Water Heater on All the Time?
Some people believe that leaving their water heater on all of the time would save them money in the long term. This is not always true. Despite its widespread acceptance, this frequent misperception can have serious implications. If the water heater is left on all of the time, the expense of keeping the water hot significantly increases. It is possible to save anywhere from 8 percent to 34 percent on your energy bill if you simply heat the water that you require. This depends on how much you use the water ().
It should be noted that this circumstance only applies to water heaters produced before to 1997.
One method by which the water heater does this is by the use of a two-element system in which neither element operates at the same time.
This prevents the system from operating at maximum capacity all of the time.
Why Does My Water Heater Have a Timer?
Water heater installations do not include timers as a typical feature. You may, on the other hand, be able to acquire a home that already has a water heater timer installed. A water heater timer is fitted on a unit in order to reduce the amount of energy consumed by the unit. The water heater is turned on to guarantee that just the water that is now being used is being heated. It is possible to set and manage when your water heater goes on, allowing you to create the exact amount of hot water you require at any given time using this small electrical gadget.
How to Install a Timer on Your Water Heater?
If you have an electric or gas water heater, you may install your own water heater timer. We’ll go over the process of installing a box timer on an electric water heater because it’s the most popular form of water heater. The following are the processes and materials that will be required for this do-it-yourself job (on an electric water heater):
Tools and Supplies
- Circuit tester, slip-joint pliers, screwdriver, wire cutters, wire remover, needle-nose pliers, water heater timer, and other miscellaneous tools
Step 1: Prep work
Exit the packaging containing the box timer you purchased and carefully remove the knockouts from the case. These allow the wire to enter and exit the box timer at the appropriate times.
Step 2: Turn off the power
Turn off the 220v circuit breaker that supplies electricity to the water heater.
Water heater should be designated on the circuit breaker, which will be a double breaker. When you’re sure you’ve shut off the power and that no current is flowing to the water heater, check with a voltage stick.
Step 3: Select a mounting location
We’ll need to put the box timer on a wall near the water heater so that it’s easily accessible. Select the location where you want the timer to be placed (somewhere close to the water heater). Make a template of the casing and mark the locations of the mounting holes on the wall.
Step 4: Mount the box timer
Drill pilot holes in the wall at the areas designated with a pencil, and then screw the casing to the wall with screws. These will be included in the box that contains your box timer.
Step 5: Verify the power is off
To get access to the wire connections, remove the access cover located on the top of the water heater. Check to see that the electricity to the water heater has been switched off with a multimeter or a voltage stick.
Step 6: Disconnect the water heater wiring
Remove the incoming wiring that is linked to the water heater and route it through the knockout hole on the left side of the timer’s enclosure. Remove the wire nuts from the work area since you will need them again in a short while.
Step 7: Connect the water heater
Obtain a new section of wire to connect the box timer to the water heater. Make certain you utilize the same gauge as you did for the prior one. 12″ of insulation should be removed from the wires before connecting them to the device. To secure the wiring, re-use the wire nuts that were used for the initial connection. Make certain that the wiring to and from the water heater is routed through flexible electrical conduit with connectors on both ends.
Step 8: Connect the wiring to the timer
Connect the ground cable to the timer socket using the timer plug connector. Each bare wire end should be shaped so that it fits correctly beneath the lug. In your installation instructions, you should find a wiring schematic that you may follow. The wire should be connected to the relevant connection slots. Tighten the screws on the timer to ensure that the wire is properly attached.
Step 9: Turn the power back on
Restart the water heater by resetting the breaker or re-connecting the electricity.
Step 10: Program the timer
Set the timing to your parameters based on what you need to accomplish.
Water Heater Timer Savings
It is possible to calculate the amount of money you will save by installing a water heater timer based on three key factors:
- The normal operating cost of your water heater
- The type of water heater you have and the amount of fuel it consumes
- And the total amount of water you use.
Using a water heater timer can result in an annual energy savings of around 25 percent, according to some estimates. Suppose your usual yearly running expenditures are $300. You may expect to save around $75 if you use this method. This almost completely covers the cost of the gadget in roughly a year. For example, if you keep the water heater in good working order and operate the timer consistently for 10 years, you will save an estimated $750 during that period.
Does Turning Off Your Water Heater Save Money?
Turning off your water heater when it is not in use, like you would with other appliances, can help you save money on your energy bill each month. When the unit is turned back on, a little amount of heat will escape, regardless of how effectively it is insulated. It is believed that the amount of energy lost accounts for around 10% of your entire expenditure. If you travel frequently, though, shutting off the water heater while you are away will save you money.
It’s important to remember that if you’re going to be gone for many days and turn off your water, you should also switch off your water heater, since this might cause damage to the device and prevent it from heating efficiently.
Which Type of Water Heater is the Cheapest to Run?
Based on your local utility bills, gas water heaters are generally more cost-effective to operate than electric water heaters in general. Because gas units are often more costly, they have a higher up-front expense. Long-term, however, the money you save on utility costs will be well worth the effort. The difference in price is frequently made up for within the first year of ownership!
What are the Best Ways to Save Energy?
Saving energy (and money) is less difficult than you would expect. Begin today by completing the following tasks:
- Reduce the length of your showers — cutting your shower time by just four minutes each time will save you up to 4,000 gallons of water per year and as much as $100 on your yearly water bill. Invest in a low-flow showerhead, which may reduce the amount of water you use each time you shower by as much as half. Consider taking showers instead of baths– a full bathtub consumes roughly 70 gallons of water each time, whereas simply a five-minute shower uses between 10 and 25 gallons of water
- Run your dishwasher and washing machine just when they are completely full — this applies to both. When washing garments, try to use cold water whenever feasible. Install aerators in your faucets to limit the flow of water and save up to $20 per year
- Water heater blankets are recommended for areas that receive chilly winter temperatures.
After everything is said and done, a water heater timer is a little device that attaches to your water heater and allows you to program the time it will turn on and off (whether it is a gas or electric unit), which may help you save both energy and money. The amount of money you save is influenced by a number of factors other than the timer itself. It is dependent on the operating costs of your unit, the type of heater you have, and the amount of water you consume. If you have a newer, more energy-efficient water heater that was manufactured in or after 1997, the timer is probably not necessary because standby losses are often relatively minimal.
Wishing you the best of luck with your future house upgrades!
Before beginning any job, you should contact with a competent expert and verify that all necessary permits have been obtained.

A Quick Guide To How A Solar Hot Water Heater Works
Conservation Published on the 5th of December, 2014 | by Peter Young. Solar hot water heaters (here’s one solar water heater option) are a terrific way to make your house more energy efficient, but if your system isn’t properly installed and maintained, it may not actually save you any money in the long run. Fortunately, there are a couple of fast and simple checks you can perform on your own to ensure that your system was properly installed and configured. Simply follow the instructions in this tutorial to guarantee that your solar hot water heater is correctly installed and functioning.
- There are two types of solar water heaters: active and passive.
- Passive ones, on the other hand, do not.
- One method is direct, in which water is simply pumped up to the roof and heated directly by sunlight in a solar collector.
- These are particularly effective in tropical areas.
- According to Energy.Gov In closed-loop systems, an antifreeze fluid is circulated up to the roof, where it is heated, and then cycled back down to a heat exchanger, where the heat is transmitted to the water tank, thus indirectly heating the water.
The heated antifreeze is then recirculated back up to the roof, where it is cooled once more. For the sake of this study, we will discuss direct circulation pumps; nonetheless, the mechanics of these pumps are not that dissimilar from those of indirect circulation pumps.
A quick guide to how a solar hot water heater works
The Fundamentals: Let’s start by watching a brief movie to acquire a better understanding of how these systems work: While your system may not be similar to the one seen in the video above, the fundamental principles of water heating are still in effect when it comes to the process of heating water. Allow me to walk you through the many settings and controls that are in place to inform your system when and how to perform its various functions. System Preferences: In order for your solar hot water heater to function in combination with either your gas or electric water heater, specific configurations will need to be in place to guarantee that they operate together flawlessly.
Ideally, this box will resemble something like this: This small grey box has a timer, which regulates the operation of your electric water heater by telling it when to turn on and off during the day.
Here is a closer look at the interior of the box and what it should look like if everything is configured correctly: A yellow time dial with a number of pins linked to it may be found within the “small grey box.” The time dial spins on a 24-hour cycle, and pins are set at the intervals you choose for when you want your electric water heater to turn on and off, according to your preferences.
- Ideally, you want your electric water heater to turn on for two different two-hour intervals throughout the day on a regular basis (4am-6am and 6pm-8pm).
- During the day, the solar heating will keep the tank warm, and configuring the electric/gas backup to turn on between 6 and 8 p.m.
- The system will automatically turn on from 4 a.m.
- to refill the tank with hot water if it is utilized during that time period.
- Double-check that the timer is displaying the correct time.
- Setting the pins to the correct times will be ineffective if the timing is incorrectly set.
- When there is a power outage, this will most likely need to be reset.
Loosen the screws that hold the first set of pins in place.
Once the pins are free to travel across the face of the timer, they should be able to do so with ease.
Set your first set of pins at the times you want your lights on and off.
Once they’ve been aligned to your desired timings, just tighten the screws until they’re no longer loose in your fingers.
Keep in mind that you want your backup system to be “on” at 6 p.m.
Please have a look at your Delta T value (the device that controls your solar hot water heater) A brief description of the Delta T is as follows: This is the mechanism that regulates the operation of your solar hot water heater, and it informs your system when to push water up to the solar panels to heat them up.
However, there is a switch on the gadget itself that you are more than qualified to examine and, if necessary, alter.
It is recommended that you leave the switch in the “Auto” position if you will be at home during the week, and the switch in the “On” position if you will be away on vacation during the week.
If you’re having issues with your Delta T system, we urge that you contact your installer for help as soon as possible. Flickr Creative Commons (Solar Hot Water Heater), Forest City Military Communities, Energy Evolution, and Delta Controls provided the images for this post.

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.

Water Heater Timers
Putting a timer on an electric hot water tank so that it is turned off for the most of the day makes sense if no one will be home during that period. If there is no access to natural gas, how about using a timer on a tankless electric water heater? – Bill Geary, Belfair WAAnswer: Bill Geary, Belfair WA
Efficiency of Timers on Conventional Electric Water Heaters
Gautam Dutt, a Princeton Energy engineer, says that putting a timer on an electric water heater will work pretty well if your daily hot water use is less than one water tank load, or if the hot water heater will be turned off for a period of many days at a time, such as during a weekend. The water tank was insulated in the 1980s because Dutt believed that it would be more feasible to insulate it for shorter time periods or at higher rates of hot water usage. Modern hot water tanks, on the other hand, are well-insulated when they are sent from the manufacturer, therefore insulating a hot water heater tank may result in failure to follow the manufacturer’s recommendations, voiding the warranty, or making the water heater hazardous (if for example you covered the pressure-temperature relief valve).
If you factor in the losses associated with hot water distribution pipes, the efficiency of the water heating system reduces to around 60%.
EFFICIENCY OF THE WATER HEATER We present a comparison of the energy efficiency of several models of water heaters in this section.
What is the Energy Efficiency of Electric Tankless Water Heaters?
Tankless electric hot water heaters, according to Dutt, perform best when hot water demands are minimal and when hot water usage points are concentrated in a single area of the structure (as opposed to having the tankless water heater deliver hot water through long pipe runs to distant points of use from the heater itself). It goes without saying that this is easier to accomplish in new construction than it is in a hot water heater retrofit. We also note that, due to the fact that tankless water heaters have zero or extremely low stand-by losses, implementing a timer on an electric tankless water heater would often result in no net benefit.
- The result is that you won’t be able to shower and wash dishes at the same time from a small tankless electric hot water heater system, and low hot water demand appliances will be required.
- The implication is that it is unquestionably more efficient to avoid boiling water while no one is actually in need of it.
- More information on these systems may be found atTANKLESS WATER HEATERS andShould I Convert to a Tankless Heater?
- The heater we describe atIndirect-fired Water Heaters, in our opinion, should be considered by readers who require a large amount of hot water that is heated effectively as well.
- Examine the timer on your water heater if your hot water isn’t operating properly: Some electric water heaters are equipped with a timer (as seen in the images above), which helps to reduce power costs by turning the heater off during periods when no one will be using the hot water heater.
- Within the timer cover are instructions for adjusting the water heater’s timer setting.

Reader CommentsQ A
(Monday, March 12th, 2015) “Our electric water heater provides far more hot water than we use,” Peter Heier explained. Would it be more energy efficient to disconnect the bottom element; in other words, would the lower section of the water remain comparably chilly if the lower element were disconnected?
Peter I’d start by reading the owner’s handbook for your heater to learn more about how its elements operate. On many water heaters, the second element does not turn on unless the water heater is forced to do so by demand. Because stand-by losses on current water heaters are not significant, I’m not sure what we’d gain by doing so – do let me know the make and model of your water heater, and we’ll look into it more.

How Water Heater Timers Save Money – Energy & Water Conservation Blog
Timers for water heaters Turning on the hot water does not imply that it is being warmed up. It all seems a little surreal, doesn’t it? Even when the hot water is not being used, your water heater is working hard to keep the water hot for you – a process that consumes energy and increases your heating cost unnecessarily. In this case, installing water heater timers is a straightforward solution to the problem. These gadgets provide you greater control over when your heater works, allowing you to reduce the amount of money you spend on electricity (translation: they will save you money).
Cost of Heating Water
Water heaters, in contrast to house heating, which is only required during the colder months, are operational all year. Whether it’s raining or shining, snowing or shining, we all take hot showers all year.
In the average house, this equates to around 18 percent of total energy consumption being allocated to water heating — the second highest energy consumption in the home. The percentage can increase or decrease depending on a variety of circumstances, including:
- No matter if your state has peak electric price hours or not, The number of people that use hot water in their house
- Showers or bathtubs are available. How long a shower lasts, and so on
Heaters are always working to maintain water at a high temperature and ready for use, whether or not someone is in need of hot water. When it comes to money, if your heater is a 5500 watt tank, your heating bill will be between $50 and $60 a month, at the very most.
How Timers Work
Programmable water heater timers are gadgets that allow you to regulate when your water heater is switched on and off. Instead of providing hot water throughout the day, your water heater will only supply hot water when it is programmed to do so with the help of this gadget. Water heaters and timers are most effective when used in conjunction with one or more of the following strategies:
- Set the timer to only boil water during off-peak hours
- This will save energy. Reduce the amount of hot water you use during peak hours. Insulate the water heater (be sure to follow the manufacturer’s directions for your particular type of heater, whether gas or electric)
- Maintain a 6-month flushing schedule for your heater to avoid the accumulation of mineral deposits (dirt that settles to the bottom of the tank, such as sand and stones)
It is simple to install a water heater timer, and it will work with any current heating system. It will provide you greater control over your hot water energy consumption and heating bills.
