It's noisy
I've installed them in previous houses for the hot water heater and now I've got to replace my current one after 19 years. They do save money (about $20 per month for my 50 gallon 220v water heater) but it operates by using mechanical gears and switches and consequently is very noisy. They are easy to program and reliable, but put some thought into where you mount it, due to the noise it makes.

Too Loud
I agree with the other review. I use it for a 220V air conditioner. While the AC is louder than the timer, the timer is running all the time, and especially annoying inside.

too noisy
Although the product functions well, it better be used in a garage or other remote area. Mine is in the laundry room and the clock groaning can be heard in the adjoining bath as well as the laundry room. It was relatively quiet for 2 years then became noisy. in addition, unless you live in an area with extremely expensive electric rates the $56.00 cost plus installation might put your payback time in the distant future. Fortunately I installed my own but remember it is 220 volts we're talking about here. I have been told that the efficiency of current hot water heaters (better insulation etc.) makes the use of this clock to save money a dubious endeavor.
