It's not recommended to completely turn off a water heater, but you can a significant amount of energy—and money—while on vacation by switching the water heater to vacation mode.
If you have an electric water heater, it is recommended that you shut off the power and the cold water supply to the water heater if you are going away for any length of time. You will save electricity and limit any damage in case the tank leaks. Upon your return, do a visual inspection of the water heater.
It's generally best to avoid turning your water heater off too regularly. Some homeowners try to save money by switching off their water heaters when they don't need them, but the savings are unlikely to be significant enough to justify the additional wear and tear on your machine.
WAPT spoke to four plumbing companies that all said that homeowners should turn off the water heater if the water is not running for more than 24 hours.
Instead of Turning It Off, Try This
Just turn your water heater's temperature down to the lowest setting. This keeps your water from freezing, but also means you're not wasting money keeping your water piping hot (hint: you should be keeping your water heater at 120 degrees for normal household use).
No, you do not need to turn off the water heater if you shut off the water to the house. However, doing so is a good practice and highly recommended because it eliminates the possibility of damage caused by having the heat turned on when the water heater is empty or low on water.
Remember to shut off the main water supply to your home any time you're planning to be away for more than 24 hours. Yes, that includes weekend breaks. It's the best way to avoid serious water damage in the event of a plumbing failure.
Vacation mode is a setting on your water heater system that allows you to run your boiler at lower temperatures than normal, saving energy. Typically, manufacturers set vacation mode to 50° F—well below the warmth you need to heat your home, but hot enough to prevent any water from freezing while you're away.
How long will a hot water heater stay hot without power is a common question among users of hot water. Actually, the answer is 60-70 minutes (for a gas tank water heater) 120 minutes (for an electric tank water heater).
No it wont hurt the water heater. Turning the gas on and allowing the burner to operate with an empty water heater would damage it, but no gas, with or without water in the tank will not hurt anything. Be aware, water left in the tank may smell like rotten eggs until flushed for 10 mins or so prior to use.
A daily shower is a great way to wake up and face the day but can be hard on your water heater if you take long showers. The heater will have to pump this hot water up to the tub to meet your needs and may need to warm up even more water if your shower is too long.

It's not recommended to completely turn off a water heater, but you can a significant amount of energy—and money—while on vacation by switching the water heater to vacation mode. If your heater doesn't have vacation mode, simple lower the temperature several degrees to prevent it from cycling on and off so often.
Any time you go on vacation, it's best to also turn off your water heater as well. Turning off the source of the heat (gas, electric) while you're away will not damage your water heater. This will save you in power (gas) and potential damage if it leaks too.
If you have a gas system, twist the dial on the top of the thermostat from the ON to the OFF position. For electric hot water heaters, switch the circuit breaker for the water heater to the OFF position.
Your water heater may be turning off because it is short-circuiting or because it has other electrical problems. Such damage may have developed from water damage, impact or wear-and-tear. This is also a problem that's better left to the professionals.
A good guideline is to increase the thermostat 5 to 10 degrees warmer than you typically do during the day without reaching above 85 degrees. This is an ideal compromise between conserving energy and protecting the interior of your home.
It's generally best to skip turning off the water heater and use the vacation mode or lowest setting to avoid problems.

How Long Can You Turn Off Water to a Toilet? Like turning off your toilet's water for a night, it's safe to do so for a week. While you can keep your toilet water off for as long as you'd like, we wouldn't recommend it unless you have a problem with your toilet's plumbing system.
Before you leave on your trip, give your toilet bowl a quick clean. Then, sprinkle in a bit of baking soda and give it an extra flush to make sure there's no lingering debris in the pipe.
Yes it is safe to leave the water heater in pilot mode while flushing. You do not want the burner to fire while the tank is empty as this can damage the tank but the pilot will not cause a problem. Added: most gas valves with a standing pilot have the temp setting and “pilot” then off settings.
