What Does Vac Mean On Water Heater

What is vacation mode?

Vacation setting is available on new water heaters with the use of a temperature control labeled “VAC.” It is necessary to activate this function when the homeowner will be away from home for an extended length of time and hot water will not be required. When you’re ready to leave for vacation, simply turn this dial to the VAC position. This mode will cool the water down to 50°F and will utilize the most energy-efficient heating mode while the heater is not in use, allowing you to save money on your energy bills.

If your thermostat does not have this type of setting, you may just crank it down to the lowest possible level.

Electric water heaters are easy to troubleshoot since they can simply be turned off at the breaker or fuse in the service panel.

It is possible to reduce your thermostat to a temperature no lower than 50 degrees F.

If you do not have any difficulties doing so, you might opt to switch off your computer altogether.

More Energy Saving Tips

Setting the water heater to “vacation mode” is not the only technique to save money on your utility bills. There are a variety of techniques to conserve energy when using our water heater. Here are some suggestions:

  • Set the temperature of the water heater to 120 degrees Fahrenheit. It is more feasible and safe to lower the temperature to this level. Using this temperature, enough hot water will be produced to provide every family. Despite the fact that a dishwasher requires 140 degrees, a water booster may accomplish this task. Nowadays, dishwashers are equipped with a built-in temperature booster. Do the routine maintenance, which is something your family may think about doing. Every water heater requires regular maintenance in order to operate efficiently. A water heater that is energy efficient will save you money.

How to Set Your Water Heater to Vacation Mode and Turn It Back

Water heating systems consume a significant amount of energy to run. As a result, an increasing number of environmentally aware people (as well as those who just want to cut their utility bills) are learning how to set their water heaters into “vacation mode” with the goal of conserving energy and saving money. So, what exactly is vacation mode, and where do you go to locate it on your computer or smartphone?

Water Heater Vacation Mode: What Is It?

In your water heater system, there is an option called vacation mode that allows you to run your boiler at lower temperatures than usual, therefore conserving energy. In most cases, manufacturers set vacation mode at 50° F, which is far lower than the temperature required to heat your house, but high enough to keep any water from freezing while you’re gone. Certain systems will not require you to make any changes to the manufacturer’s settings. It is possible to regulate the temperature of the water by turning a dial.

Where Do You Find Vacation Mode And How Do You Use It?

There are a variety of techniques available from water heater manufacturers for putting your unit into vacation mode, the most prominent of which is a particular setting on the thermostat itself. To check if your thermostat has a vacation mode, go to the settings menu and scroll through the options. If it does, all you have to do is choose it, and the system will take care of the rest.

If your thermostat does not have a vacation mode that is expressly stated on it, you may manually accomplish the same result as a vacation mode by setting the temperature to “Pilot” mode and leaving it there until you return.

Why You Should Put Your Water Heater In Vacation Mode

It is primarily for financial reasons that you should put your water heater into vacation mode. You have no need to heat water to 120 degrees if you are not going to be in the house to utilize it. It is a waste of energy that results in an increase in your utility costs. The other reason is to keep freezing water from causing damage to your pipes during lengthy periods of extremely cold weather. If you forget to switch off your water heating system while you’re gone and the water freezes into ice, you face the danger of cracks in your pipes, damage to your plumbing, and perhaps the need to replace your entire system.

Then, when you switch your system back on, it doesn’t work anymore, and you frequently end up with flooding in your house as a result of this failure.

In order to avoid substantial harm to your system, a compromise must be made between utilizing no electricity at all and using a little amount of heat to keep it running.

Even if your thermostat doesn’t have a dedicated vacation mode, you can still lower the temperature to keep your house safe while you’re gone on vacation.

Should You Put Your Water Heater In Vacation Mode?

If you expect to be away from your home for a few days or longer, you might want to consider turning your water heater into vacation mode. The ability to switch into holiday mode might be useful whether you’re traveling on a short work trip or a prolonged vacation.

  1. Reduce your energy expenses
  2. Save your energy resources (fuel)
  3. And Prevent frozen pipes and burst pipes from occurring. Increase the longevity of your water heater

What is Water Heater Vacation Mode?

The vacation mode option on your water heater enables you to quickly and simply adjust the temperature of the water coming out of it. When you leave home for an extended amount of time during the winter, when additional difficulties might arise, this can be very beneficial. The pilot light remains on, but it is no longer capable of heating the water to its maximum temperature. Consider the following scenario: you wish to travel for a week during the winter months. If you don’t utilize your vacation mode, your water heater will continue to consume the same amount of energy resources to heat your water as it did before you turned it on.

This temperature dial may be found on the side of your water heater, at the bottom.

When you return, re-adjust the thermostat to the appropriate temperature.

ProsCons of Your Water Heater in Vacation Mode

There’s no denying that switching your water to vacation mode might be beneficial. However, there are certain disadvantages that you should be aware of. Let’s take them one by one.


  • Utilizing the water heater’s vacation mode option is simple and straightforward. It is an ecologically responsible option that reduces the amount of gasoline and energy wasted. The cost of maintaining water in your tank at full temperature while no one is home to use it will be modest (depending on how long you are gone), and you will not be responsible for it. It can extend the life of your water heater by reducing the amount of energy it must expend to heat water to a temperature that is not required


  • During vacation mode, the water temperature in your hot water heater drops to a lukewarm level, making it less effective. This has the potential to generate an environment conducive to the growth of germs. When you return, you may notice a strange odor in your water until the bacteria is eliminated by restoring the heat to its regular temperature or by applying bleach
  • However, this is temporary. A water heater may not be available if you live in a multi-unit housing complex where the water supply is shared by all of the residents. The simplest solution in this situation is to turn off the water shut-off valves that are positioned near every fixture (such as beneath your toilet, under your kitchen faucet, and so on)

A Sure-Fire Alternative to Vacation Mode

Let’s suppose the disadvantages exceed the advantages. Here’s a terrific alternative: simply turn off the water supply to your house from outside. This will eliminate the following two potential issues: a)

  1. The buildup of water pressure (especially from freezing water). Eventually, the frozen water expands to the point where the pipe breaks open completely. When you return, all of the water drains away
  2. Unknown water leaks that build and cause harm while you’re away While a leak that occurs while you are at home may go undetected for a day or two, a leak that occurs when no one is home might do significant damage since no one is around to stop it. The amount of time that elapses between the time a leak starts and the time it is detected has a direct influence on the severity (and expense) of water damage.

It is common for the main water line shutdown valve to be positioned inside your home. As a result, it will most likely be on a wall that is nearest to the street, as this is where your water supply is connected. First, look for cracks in a lower wall, such as one in your basement, behind a water heater, or in the laundry room. If you have a whole-house water softener, it may also be in close proximity to that unit. In places where the temperature is consistently high, the main water shutdown valve will be located near an exterior wall.

What Else Can You Do?

Although the purpose of taking a vacation is to get away from everyday life for a bit, if you do not take certain precautions ahead of time, you may be in for a rude surprise when you return. Other than shutting down a mainline (such as the main sewer line) or placing your water heater on vacation mode, there are several steps you may take to avoid flooding:

  • Adjust your thermostat to 65 degrees Fahrenheit throughout the colder months of the year. Keep in mind that the areas between pipes are significantly colder than the temperature you have set on your thermostat. If you drop the temperature below 65 degrees, you run the danger of your pipes freezing and exploding. Before leaving, check for any leaks that may have occurred. A trusted neighbor or a family member should check on your home every few days (they can also pick up your mail and place it inside your home). If you don’t already have one, you should think about getting one to protect your home. Ensure that all batteries are fully charged and the gadget is set to “away mode” before leaving the house. For additional information on this option, speak with your plumber. Pour a pail of water into the sump pit to ensure that your sump pump is operational before you leave town. If the pump does not activate, a plumber should be contacted. Here’s an article that explains how to determine whether or not your sump pump is operational

Never leave your house with the thermostat set below 65 degrees for an extended length of time. Keep in mind that the inside of your outside walls is cooler than the interior of the room. As a result, pipes in those places are more susceptible to freezing if the temperature is not maintained at an appropriate level.

Final Thoughts

Putting your water heater into vacation mode is a simple, yet sometimes overlooked, step in safeguarding your house from potential disaster. Even a little leak, if left unchecked for several days, can cause significant water damage to the home. The amount of time that elapses between the time that a leak starts and the time that it is detected has a direct influence on the severity and cost of any following water damage. However, it is not required.

Consider the advantages and disadvantages listed above and decide for yourself if it is preferable to just cut off the main water line supply valve. Remember to turn on the water when you arrive home, since this may be a more appropriate remedy for your particular scenario.

Asked in the following category: General The most recent update was made on May 1, 2020. To simulate Vacation Mode if your hot water heater does not have a vacation mode, you can manually drop the temperature to 50 degrees Fahrenheit or the lowest setting your thermostat permits. Additionally, you have the option of entirely turning off your hot water heater. Water heater vacation mode refers to the heater settings that are lower than the normal levels at which a water heater is operational. Leaving your water heater in the vacation mode guarantees that the water heater does not spend electricity while no one is present in the building, so conserving energy and lowering energy costs for you.

Turn off your water supply.

This will offer you extra peace of mind and will save you from stressing at the airport the day before you’re scheduled to leave.

However, while it is not suggested to totally turn off a water heater while on vacation, you may save a considerable amount of energy—and money— by putting the water heater to “holiday mode.” You may just reduce the temperature of your heater several degrees to avoid it from turning on and off so frequently if your heater does not have a vacation mode.

The Importance of Draining Your Water Heater at Your Residence Some new water heater owners have asked me the following question: “Should you drain a water heater while it is not in use?” My response is always a resounding “yes.” Regardless of the variations between these heaters, it is important to drain the water since the silt inside the tank might clog the spigot.

Adjusting Your Water Heater Settings: How To Maximize Efficiency

Not many people are aware that selecting the proper water heater settings may result in substantial savings. Indeed, while the majority of people don’t give their hot water heater settings a second thought, they are actually highly critical in many situations. Not only will it save you money, but it will also make your showering experience more pleasant as a result of it. Here is a breakdown of the procedures.

Default Hot Water Heater Settings Can Vary

Temperature settings on water heaters in Phoenix are frequently set to as high as 140 degrees Fahrenheit as the usual setting. That is far greater than the majority of individuals require, although manufacturers do so for a variety of reasons. The Department of Energy states that germs cannot thrive in water that is so hot, among other reasons. Increased gas or electric water heater settings can be beneficial for people who have weakened immune systems or respiratory illnesses. In addition to impressing consumers who have presumably recently replaced their tank since the previous one had ceased performing correctly, high temperatures can also be beneficial.

Once this psychological trick wears off (and assuming you don’t have a sickness that makes you particularly susceptible to bacteria), you’ll likely receive far more joy from saving money on your water bill, which we’ll teach you how to achieve in the next section.

How Much Are Your Gas and Electric Hot Water Heater Temperature Settings Costing You?

As a general rule, every 20 degrees you reduce the temperature of your gas or electric water heater, you may expect to save as much as ten percent on your utility bill. That’s not too shabby after all! In reality, it adds up over time, and you can almost certainly come up with a number of better uses for the money you save. “But hold on a minute,” you may be thinking. “I really enjoy taking hot baths!” However, you almost probably do not take showers above 140 degrees Fahrenheit, which can cause scorching because of the high temperature.

No matter what happens, raising the temperature is a simple process.

How To Adjust Your Gas and Electric Hot Water Heater Temperature Settings

Now that you understand why you should reduce the temperature of your water heater, let’s look at how to go about doing so.

Step One: Get An Accurate Temperature Reading

It’s likely that the thermostat dial linked to your water heater tank is not functioning properly. As a result, you should really use a thermometer to monitor the temperature of the water flowing out of your faucet. The Department of Energy suggests that you measure the amount of water that is flowing out of the faucet that is the furthest away from your water heating system. Make a note of the settings after you’ve found them.

Step Two: Figure Out Where to Make the Adjustment

There are several distinct types of water heaters, and we’ll go through each of them separately.

Electric Water Heater Settings

In the case of an electric water heater, you must modify the hot water settings at the top and bottom of the unit. Both controls, which are often concealed behind a panel and consist of knobs that you crank to establish the appropriate electric water heater thermostat settings, are typically located on the same side of the panel.

Gas Water Heater Settings

Newer gas water heaters are equipped with temperature controls that are similar to those described above in the section on electric water heaters. Most gas heaters, especially older models, feature a temperature knob near the base that may be easily adjusted to the appropriate temperature.

Tankless Water Heater Settings

Newer gas water heaters are equipped with temperature controls that are similar to those described above in the section on electric water heating systems. Most gas heaters, especially older models, include a temperature knob at their base that may be easily adjusted to the desired temperature.

Step Three: Make The Adjustments

If you have an electric unit, make sure to turn off the electricity to it before modifying the hot water heater settings at the top and bottom, as we previously discussed in detail. This may be accomplished simply turning off the necessary settings on your circuit breaker panel. Doing so is also recommended in the case of a gas water heater that consumes some power (as some newer units do). But hold on a minute! What temperature should you choose as a starting point? The Department of Energy suggests that you set your heater to 120 degrees Fahrenheit for the best performance.

Some water heater temperature controls now include buttons that read “A-B-C” instead of numbers, which makes them easier to use.

Generally speaking, A denotes 120 degrees, B denotes 130 degrees, and C denotes 140 degrees, respectively. To double-check these settings, consult the owner’s handbook for your water heater.

Step Four: Tweak the Settings as Necessary

After you’ve made the necessary adjustments to your gas or electric water heater thermostat settings, you may discover that you need to make a few more adjustments to get the best setting. You’re trying to strike the perfect balance between comfort and cost-effectiveness. If that’s more than 120 degrees Fahrenheit for you, there’s nothing wrong with that. Make the necessary adjustments!

Frequently Asked Questions

It is nearly guaranteed that a temperature setting of 150 degrees will be too hot for your water heater. The likelihood of experiencing scalding is quite high at that temperature. You should be concerned about your youngsters, who may experiment with the temperature settings on the faucets while completely unconscious of the risk and end up scorching themselves.

What Is The Maximum Temperature For A Water Heater?

Your water heater will almost likely overheat if you set the temperature to 150 degrees or above. You will almost certainly endure scorching at that temperature. You should be concerned about your youngsters, who may experiment with the temperature settings on the faucet without realizing they are in danger and end up scorching themselves.

Is 140 Too Hot For A Water Heater?

Yes, temperatures above 140 degrees Fahrenheit are uncomfortable for the majority of people. The only exception would be persons who require an additional layer of protection against germs, which cannot thrive in water at that temperature. However, because such a state does not protect you from scorching, you will almost certainly need to install an equipment at the showerhead that cools the water before it is discharged from the showerhead.

Why Is My Water So Hot?

If you haven’t changed the settings on your hot water heater in a long time, they are most likely still set to the factory default of 140 degrees. The latter is especially true if your hot water heater was only recently installed; the old one was almost certainly altered at some time over the years, whereas the new one is set to the manufacturer’s recommended settings.

What Is The BEST Water Heater Temperature Setting?

Please keep in mind that this content may contain affiliate links. This means that, at no additional cost to you, we may gain a small profit on purchases made via our links. If you have already set the temperature and are thinking to yourself, “I don’t have any hot water,” or “I don’t have enough hot water,” there are a few variables that might be causing the problem. If all else fails, it’s possible that the heating element is faulty and has to be replaced.

How To Check Your Water Heater Temperature

The majority of water heaters do not have a temperature gauge with a digital readout on them. Temperatures or heating ranges are marked on thethermostat, rather than numbers. A cup and a culinary thermometer will be required in order to correctly determine the temperature of the hot water heater. If you haven’t used your water heater in at least one hour, turn on the faucet that is nearest to it.

Allow the water to run for at least one minute to ensure that the water is at its warmest possible temperature before filling the cup with it. Insert your cooking thermometer and make any necessary adjustments to the temperature settings.

Recommended Temperature Settings

Water heaters are pre-programmed to operate at OSHA-recommended temperatures, which are around 140 degrees. The Environmental Protection Agency, on the other hand, recommends lowering the thermostat down to 120 degrees Fahrenheit to save power use and using a booster heater to attain sanitizing temperatures at certain outlets. Another point of view is that lower temperatures are preferable for homes with little children, although higher temperatures are more effective in cleaning and sanitizing surfaces.

However, the temperature is low enough to avoid scorching while being high enough to destroy hazardous microorganisms.

How To Turn Up Your Water Heater

If you are dissatisfied with the suggested temperature of your hot water heater, you may alter the settings to receive extra hot water. Although electric water heaters may require a screwdriver and potentially a tiny wrench or socket, most hot water heater settings are straightforward to modify. Keep in mind that the thermostat is factory configured to a recommended temperature, and that altering the setting may increase the risk of significant burns from the appliance.

How to Set Temperature on a Gas Water Heater

The temperature of a gas water heater may be adjusted by turning the setting knob on the water heater. The majority of gas control valves have a knob with different designations on them, such as A-B-C. Control valves for gas water heaters may be labeled differently depending on the manufacturer. In the majority of circumstances, the following is what each label indicates:

  • The temperature of a gas water heater may be adjusted by turning a control knob on the unit. For the most part, gas control valves are labeled A-B-C on the knobs that are on them. Control valves for gas water heaters may be labeled differently depending on their manufacturer. Generally speaking, the following is what each label signifies:

There is a “Vacation” setting that appears from time to time. This does not heat the water, but it does ensure that the pilot light remains lit.

How to Set Temperature on an Electric Water Heater

There is a “Vacation” setting available on occasion. However, the water will not be heated as a result, but the pilot light will remain lit.

Factors That Affect Water Temperature

Some of the things that may influence the temperature of your hot water include the distance between the water heater and the outlet, the way the pipes are built, and the quality of the heating element itself, among others. Because of the length of the pipe and the small bore size, it will take longer for the hot water to reach the opening. Additionally, pipes that run beneath or outside the residence may be exposed to freezing or freezing temperatures in the winter and summer. Installing a hot water recirculation system in a large house may be worth considering since it can reduce the amount of time it takes to heat water in all of the property’s outlets while also resulting in significant cost savings over the long term.

A Few Suggestions Before You Go On Vacation – Water Heater, Programmable Thermostat – Gazifère

Before you embark on your vacation, consider the following suggestions to help you minimize your energy use a little and, most importantly, to help you sleep better while you’re away.


Reduce the temperature on the thermostat. You should set the thermostat two to three degrees lower than usual if you are just going to be gone for a couple of weeks or less. If your thermostat is preset for various temperatures at different times of the day and night, it is recommended that you adjust it to the temperature you prefer at night. If you decrease the temperature any more, you will spend less energy while you are away, but when you return, you will have to use more energy over a longer period of time to compensate for the heat that has been lost through the floors, walls, and ceilings throughout the house.

When you return from your trip, just cancel the HOLD option on your thermostat’s programming menu to revert it to its usual programming mode.


Your traditional storage space -type water heaters maintain water temperatures between 55 and 60 degrees Fahrenheit 24 hours a day because it requires less energy to maintain water at the proper temperature than it does to continuously heat cold water. Switching off the water heater fully is only more cost-effective if you plan to leave it off for a few weeks or longer. If this is the best choice for you, consult your appliance’s user manual to learn about the procedures you need take if you are going to be gone for a long amount of time.

  • In the case of a leak from the tank, you may also turn off the cold water supply to the water heater in order to reduce the amount of damage.
  • Then turn on the cold water supply and turn the dial back to WARM, using the biggest square on the dial for this setting (see photo).
  • Water heater with a power vent If you have a power vented water heater, you may simply turn it to “vacation” mode to conserve energy.
  • Then just unplug the water heater from the mains.

water heater while on vacation – Forum

The time now is 10:05 a.m. on January 31st, 2011. Kathy55 has been a member since 02/12/0634 postings in her lifetime. When we leave on vacation, we cut off the water to the house, and we’re wondering if turning on the vacation setting on our gas hot water heater would be adequate given that the water has been turned off in the house. We are normally away for two to four weeks at a time. Thank you very much.

(similar to the vacation setting on the last one)I will be departing for a lengthy winter vacation of 3+ months beginning in late November.

I’ll be gone for a week.

BV00283805:35PM The water heater is located in the garage, where the temperature has the potential to drop below 32 degrees.

Would the sole issue be that the valve was not closed properly, resulting in gas being wasted?

07/06/14 BV00489609:04AM Should we switch off an electric heater if it hasn’t been used for two or three weeks?

As a matter of fact, it is a brand new one.

But, if you know it isn’t going to dip below freezing, you may turn off the electricity to it.

Friday, June 15, 2015 What if I put my gas water heater on “pilot” while I’m away (for roughly 2 weeks), and then switch off the water supply to the house?

Is it possible to just switch the water supply back on and set the water heater to “on” after I’ve done this?

07/26/16 BV01235209:12PM What about electric water heaters, do you think?

Is this preferable to completely shutting down the heater’s power?

December 7, 2016 After a few months of operation with the water heater in vacation mode and the water input turned off, is there any possibility of considerable evaporation of the water in the tank?

May 22nd, 2017 It is customary for me to switch off the water main.

I was debating whether I should simply unplug the water heater, put it on vacation mode, or leave it alone.

Leaving the water heater (natural gas with power vent) alone has been a good decision.

Usually, three to four days are required.


Is it dangerous to leave a tank on pilot for a couple of weeks, or even longer, than that?


I have a sensor alarm that detects when there is a leak.

Should I turn off the water supply to the tank in order to avoid flooding?



Is it okay to leave it that way for the next eight monthsBV02387504:24PM|

I intend to turn off the water supply to the house and put the water heater to the vacation setting.

I’m wondering if this is an excessive amount of time to leave the heater on vacation mode while also turning off the cold water supply.

Thanks BV02502807:32AM| Thursday, March 21 It is okay to leave my gas water heater on vacation mode while I am away for a few days while I have it repaired? My gas water heater is leaking from the top.
