Intermatic WH21 Electric Water Heater Timer

Dead on arrival. Manual override allowed me to turn water heater on/off but timer didn't work. Returned for refund.

Have it set for 5 to 6AM, noon to 1PM, and 5 to 6PM. Never ran out of HOT! water. Saves at least 50% of heating cost and was a snap to install. Don't understand why they don't build something like this into the Water Heater... Now there's a $$$$ making thought?

Seller shipped promptly and professionally. Item received a week before estimated date.
The timer switch works great. I have it timed to be on 3 hours in the morning and 3 hours in the evening. We have plenty of hot water. My electric bill has dropped 20%. It was well worth the purchase.

This timer works very well and is reliable. I purchased the first one of these units over 15 years ago.
Only 4 stars instead of 5 because the terminal strip could be a little more robust and handle larger wires.

I was told I could save a lot on my power bill by installing a timer so I searched the web for the best buys & how to install one. I found this site to be one of the best. I installed the timer last week & it works fine ,but I can't tell how much I am saving on by power bill at this time as it hasn't been installed long enough.
