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 is always advisable to turn off your water supply before leaving for a vacation. Shutting off the water is crucial for protecting your home from water damage through leaks or burst pipes. The last thing you want is to find the house flooded and with a foul smell when you return.
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.
While turning off your furnace can save you money on your utility bills, it can also cause more harm than good. To prevent coming home to a disaster, keep your furnace on.
If it's turned off during low temperatures, then the pipes may freeze and even burst. Instead of turning it off completely, you should set your water heater to a lower temperature than usual while you're away from home. This will save energy and eliminate the risks of damage to your unit.
If you are leaving the house empty for more than a few days, it should be safe to leave your heating on, however, even if you do turn off the water. It can be useful to have your central heating ticking over on a low temperature while you're not there with the help of a smart thermostat.
It's better to leave the hot water heater on all the time, rather than turning it on and off. This is a very common energy saving myth. But in fact, you really don't need to be heating your water all the time. Your immersion heater or boiler will heat up hot water which is stored in a tank.
Generally speaking, a gas water heater should not be turned off unless you are leaving the house for an extended period of time. Even then the better choice for gas water heaters is to just turn the temperature down. In fact, many water heaters have a “vacation” setting on the temperature control.

If your hot water heater doesn't have a vacation setting, simply manually adjust your temperature to resemble Vacation Mode by lowering the temperature to 50 degrees Fahrenheit, or the lowest setting your thermostat allows. You may also choose to turn your hot water heater off completely.
The short answer is yes, as long as you don't mind using cold water. Shutting off the input to your water heater will not affect your home's main water supply. You can still run appliances like your washing machine or dishwasher, flush your toilet, and use your shower, sink, or garden hose.
If you do not turn off your water supply before leaving for vacation, water will continue sitting in your pipes, waiting to be used.
If you find that your water heater has developed a leak, you should turn off the water via the valve on the heater to minimize leakage. If, however, the valve is broken, you must turn off the main water supply to prevent a never-ending flood.
The best approach is to set your vacation thermostat about 10 degrees higher (summer) or lower (winter) than you normally set it when away from home. This lowers the amount of time your HVAC system is running while you are away. In general, don't set it above 85° in the summer or below 50° in the winter.
To save energy, it will always be better to turn off your heating in your absence. However, depending on the dwelling, keeping a minimum temperature is advisable.
During colder months, leaving your water heater running at a low temperature helps prevent frozen pipes. When pipes freeze, the risk of burst pipes and water damage increases, leading to potentially costly repairs.
The truth of the matter is this: yes, you will use a little more energy initially when getting the water back up to temperature. However, you will use far more energy over the course of time because you'll be heating the cylinder for hours and hours when no one will be using the hot water.
