Yes. I would. If you are replacing the hot water lines, it is also a good time to drain the hot water heater and get rid of all the junk at the bottom of the hot water heater. That should be done once a year. Your hot water heater must be off when you do that, your hot water heater should be off when you drain your hot water heater. You will see boiler scale come out of your water heater. Leaving the boiler scale in your water heater makes it less efficient. It makes it harder to heat your water. It is the same as throwing money down the drain. If you want to give your money away, you should give it to the Salvation Army instead of the Utility Company.

Will a timer on a water heater save energy?
Yes. With a water heater timer I believe you can extend the life of your water heater, reduce energy consumption and carbon emissions. Some timers go so far as letting you choose the times when you most need hot water like in the morning and evening. Instead of heating water all day when you arent home or using hot water you can set the timer to come on an hour before youre home and go off when you are done for the morning or evening. This doesnt mean you are without hot water. Hot water will be stored for intermittent uses between timer settings. Some models can save you up to 30% or more on monthly hot water energy costs even. There are several companies that manufacture water heater timers for both gas and electric water heaters.
Why do some hot water heaters need thermal expansion tanks and others do not?
I believe that the larger the hot water tank, the greater is the need for an expansion tank. Water expands as it is heated. This is why all hydronic heating systems require an expansion tank. A water heater would need expansion tank when a backflow preventer or check valve is installed in domestic cold water line directly after water meter. Some areas require backflow prevention, but not all. Have to check with local plumbing authority about that.

Do you need to leave hot and cold water on to keep it from freezing?
Given that you are not changing the fluid in your water heater, and your heating source is 100% efficient, and you are paying a constant rate for your heating source, then turn off your water heater. Reason: The water in your water heater will always try to return to room temperature. The rate it returns to the room temperature is governed by the insulation around the water heater and the difference in temperature between your set point and the room temperature. So to keep the water heated to the set temperature, it requires adding the heat that passes through the insulation over time. If your water cools some amount, lets say 10 degrees, there exists a smaller temperature difference between the water temperature and the room temperature, and the cooling rate slows. This is why there is savings if you turn down your room temperature in the winter, or the water temperature.
