Just a couple of tips if you will be away from home over the holidays. Shut the water off going to your hot water tank. If something should happen, only the water from the tank will be released. For longer trips, turning off the hot water tank completely will save energy. If the temperature will be below freezing while you are away, the big risk is that pipes could freeze if your furnace goes out. Ask a neighbor, friend or family member to check on the house every day or two depending upon the severity of the weather.
