I am trying to save money, so I turn my water heater, located in my garage to vacation when I am not needing it, especially at night. Why do I have hot water when I run the faucet in the morning ?

I've seen them stay hot for 2 days or more in the summer....In all actuality..if you are cutting them off only for 1 day, you are wasting more energy when you turn them back on to heat it back up to it's full temperature...

If you turn the water off, turn the gas off at the furnace and the water heater. Of course, if it's going to freeze, you need to leave the heat on. If you leave the water on, turn the water heater to the vacation setting. Turning the house water off is often a good idea if you are going to be gone and there is no one to check on the house. If something were to break, you would have quite a mess when you got home and an incredible water bill. Be smart, though, some boiler type furnace systems need the water on to replenish the boiler if it gets low on water. I would NOT change out a water heater just before leaving on vacation. Plumbers make mistakes sometimes and you won't be home to turn off the water if it leaks.

It sounds like you may have a pilot light for the ignition and this will keep a small flame burning. Don't forget that little or no hot water is being used during the night and modern heaters are better insulated to retain heat. By turning the knob to vacation you are only shutting off the burner and not the pilot

Depending on the type of water heater, you will have a tank of water (usually about 40 gallons) heated to about 110 F. The tank is insulated to conserve energy and to prevent the water from cooling too quickly.

Water heaters hold anywhere from 30 to 50 gallons. It takes time for this heat to dissapate. I put a timer on mine that shuts off power from 10p to 6am. I have a newer unit and it holds hot water all night, because no one is using it.

It takes hours and hours for hot water tanks to cool off. If you still have hot water in the morning, good for you, your efforts are paying off.
