I have some experience from the home in PA, If your hot water system has a pilot light you might not want to shut it off completely. I did this, and ended up a leak at the flanges of the circulating pump. Fortunately we were at home, and caught the problem. Now the other problem, if you shut of the heating system completely, you better make sure it is drained and protected from freezing, as well as all of the other water pipes in the house. Be sure to put antifreeze in the traps of the toilets, etc.
IMHO, I would set to minimal heat, to prevent freezing, and have a neighbor or house watch company stop be daily or every other day to confirm all is OK.
