Title: too noisy
Review: 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.
