If you have an electric water heater, after taking your night-time showers or washing your dishes, whichever comes last, shut off your water heater. I flip the breaker that controls only the water heater. Turn it back on in the morning. There is enough hot water left in the water heater for any reason you might need it, while the water heater is turned off. I save at least $20.00 a month by doing this.

I don't believe you. To begin with, it takes a long time to heat water. Shutting down the heater after last hot water use during the evening doesn't replace the hot water you used then. You may as well shut it down at noon.
Otherwise, one should set the thermostat at a fairly low temperature and keep it there. Some people think that keeping water temp really hot and then shutting the heater down daily works. That can also scald you or a child.
I'd suggest you contact a licensed plumber and have her explain the details.
Tomatohanger is absolutely right! Also, if you turn it off in the winter time, depending on where you live and where your water heater is located, it may be frozen in the morning! (Don't laugh, I live in southeastern NC and had that happen once!) The ONLY time I would advise turning it off (and this is a huge MAYBE) is if I'll be away on a trip for several weeks, and then ONLY in the SUMMER MONTHS! But I agree with Tomatohanger in that it's just as frugal, and lots safer too, to turn it down to 120° and leave it there.
We keep the water heater set at the temperature we like for showering. No wasted water trying to blend water to the right temperature. The only thing we need hot water for is the dishwasher and that automatically heats water to the correct temperature when needed. Ruth

This is a money saving tip. I shut off my hot water heater upon leaving my house. When I get back home, I flip the breaker switch back on and have hot water in less than 10 minutes. No one is here to use it and it saves big on the electric bill.

Editor's Note: This sounds like a interesting tip. I know that shutting down your water heater is often recommend if you are leaving for a prolonged vacation. One thing you should do regardless, is make sure that your water heater and pipes are well insulated so that the water retains more heat as it stored in the heater and travels through the pipes.
There may be a safety concern with turning on and off a gas water heater regularly. With either gas or electric, you may want to call your utility company and see if they can see any safety problems with this tip. It should be pretty easy to track whether this is saving you money by comparing your current power bill to the previous years.

I was told to turn off my hot water heater during the day as it would save roughly $50.00 per month on the power bill. Wish me luck!

Home improvement stores sell a special water heater blanket that you can put around your heater to help insulate it. This reduces energy use by 10-15% -- for a family of two, that's about 21kWh/mo., or $20/yr. at 8¢/kWh. The savings are only slightly less for a family of four.
When it's set on scalding hot, you have to mix in cold water in your shower to lower the temperature, and why make your heater boil the water if you don't need it that hot? You can probably do with the temperature set to 110 degrees F or less. (06/10/2010)
