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.
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.
Does anyone know if there is any harm caused by turning off water heater when I am not home? Since I am not home all day, I am considering turning off water heater at circuit breaker when I leave. Can this cause any problems to the heater?

We have been doing this every day for years with our electric water heater, summer and winter. The water will still be warm 24 hours later. It usually takes about 15 to 20 minutes for it to get back up to full hot water. It also has never damaged either the heater or the breaker. There are timers made just for this problem tho.Our electric bill fell to 1/2 of what it had been. Nobody believed us until they saw our bill compared to theirs! LOL, Kathy, Ms.
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.
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.
