Vacation mode is a setting on your water heater system that allows you to run your boiler at lower temperatures than normal, saving energy. Typically, manufacturers set vacation mode to 50° F—well below the warmth you need to heat your home, but hot enough to prevent any water from freezing while you're away.
Using Vacation Mode while you're away from you home can be good for the environment and your wallet! Lowering the temperature of your water heater reduces your energy consumption, preserving natural resources and reducing your energy bill.
Here are some common heat up times for different water heaters, assuming the appliances are new and properly sized for the home: Electric storage tank water heater: 60–80 minutes. Propane storage tank water heater: 30–40 minutes. Propane tankless water heater: 0 minutes.
If you have an electric water heater, it is recommended that you shut off the power and the cold water supply to the water heater if you are going away for any length of time. You will save electricity and limit any damage in case the tank leaks. Upon your return, do a visual inspection of the water heater.
If there's no vacation mode explicitly detailed on your thermostat, then you can manually do the same thing a vacation mode would by turning the temperature down to “Pilot” mode, and then leaving it there until you get back.

The EPA recommendation is to always leave your water heater set to 120 degrees. This is both so that the unit loses less energy and also to prevent possible scalding. OSHA, on the other hand, recommends setting your water heater to 140 degrees in order to aid with cleaning and sanitation.

An average 40-gallon heater will only take about 30 to 40 minutes to provide heat water, while you can expect hot water from a larger tank (80-gallons) in approximately 60 to 70 minutes. Electric hot water tanks, on the other hand, will take a little longer.
