I would just shut off the main water valve in the house. You can leave the water heater alone, or turn the temperature down. If you turn the temperature down, you may need to turn down both top and bottom heating coils because some electric heaters have two heating elements. I never drain the water heater because the drain valve may leak when you refill it. They tend to become clogged with calcium over time. Also, make sure the toilets have plenty of water in the bowl and close the lids to prevent them from drying out. You should be fine for two months. If you do hire a house service, I would still turn off the water and have the service person turn it on every two weeks or so. Also, I would not recommend turning off the washing machine, dishwasher, and toilet valves because these valves are only intended for occasional use, and can often leak If you mess with them too often.
