The purpose of a water heater pressure tank is to help regulate the pressure in a water heating system by maintaining a consistent pressure level. It does this by absorbing excess pressure when the water heats up, and releasing stored pressure when the water cools down, ensuring a stable and safe pressure level in the system.

If your water is off can you leave your hot water heater powered on?

I would`nt... It serves no purpose. If the water is off there is no pressure when you turn on the tap, hot or cold, so you would be heating water you can`t use.
