It can help you to save money For poorly insulated units, the heat loss can be fairly significant. Of course, losing heat in this way leads to more energy consumption and increased
Yes, you should turn off power to the water heater, and make sure that all air is out of it before turning it back on.
You can not reduce your total consumption by a meaningful amount by turning off your water heater for some hours each day. Turning off the heater to save money only makes sense if you are not going to need hot water for several weeks or months.

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.
Well-maintained traditional gas and electric hot water heaters can last 8-12 years, or more, before it's time for a hot water heater repair or replacement. Turning off your unit while you'll be away— or anytime your main water supply is off— is a good way to prolong the life of your system.
The costs of re-heating water will largely depend on your gas/electrical rates, in the example of a month away from the home, it's more than likely that you should want to switch the unit off, even if you have to flush out a complicated system for safety reasons, the cost saved not using the water heaters electricity ...
If you decide to turn your water heater off for vacation, it might be a good idea to test it beforehand. You could try turning it off and on over the course of a day to make sure it won't cause any problems. Otherwise, it's best to just leave it on for your time away.
Pipes: Turn off water supply to the house and drain pipes to protect them from freezing. You can empty pipes by running the water and flushing the toilets after the water has been turned off. After draining the pipes, it is a good idea to leave the faucets open to prevent pressure build up from any water that remains.
For Gas Water Heaters: Turn the knob on top of the thermostat clockwise to the off position. The thermostat is located near the bottom of the water heater. For Electric Water Heaters: Go to your circuit breaker panel, find the breaker for your water heater, and switch it to the off position.

Common sense tells you the water heater doesn't use electricity when it's shut off so clearly you can save money. The energy experts say it's about $1.36 a day. The question you have to answer is whether it's worth it because there are some inherent problems with turning a water heater on and off.
A 300 litre hot water cylinder requires 15kWhrs of energy to heat it. Assuming electricity is 25c per kWhr, the cost per day is $4 (to make things easy). A heat pump will save 10 kWhrs a day (more in summer, less in winter), hence each cylinder of hot water will represent a saving of $2.50.
If you need to turn your water off for any reason, it's always safer to turn your water heater off, too. While many water heaters will be fine for a while without a water supply, reduced water pressure or a low water level inside the tank could cause the heater's components to overheat and burn.
Pipes can still burst in freezing temperatures even after you turn off your home's water. The pipes will still have water inside them, which means the water may freeze and potentially burst your pipes.
As plumbing expert Palmer says, 'Moving water is much harder to freeze than standing water, which is why dripping works. But don't leave faucets running all winter – just during freezing temperatures. Monitor the forecast and drip accordingly. '
Immediately after water service was restored to your home, the service provider should have flushed cold water from an outdoor hose bib or basement utility sink for 30 minutes. BEFORE YOU START 1. Always use COLD water when you rinse the pipes.

If you keep your water at a high temperature all the time, you will lose more heat to the environment even if the cylinder is well insulated. Your water heating costs will increase in direct proportion to the average temperature of the cylinder over the day. You will end up paying for more energy as a result.
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. It will also prevent the possibility of the unit being overloaded when you turn it back on again.
