In my experience a pilot light will maintain the water in a tank at a very high temperature as long as it is not drained completely. This is in a house where the temperature is kept at least 40 degrees and the cold water pressure is maintained to the tank. In a vacation home without heat and drained pipes the situation will be less sure. I suppose if you leave the hot water taps open, that will allow water vapor pressure to escape (open the tank drain briefly to make sure the hot water pipes are empty) Then the question is how long it will take for the water in the tank to completely evaporate. Also, it would be a good idea to wrap the tank in an insulating sleeve and attach a thermometer to the hot water outlet to check the temperature at that point with just the pilot on.
