    Customer Reviews & Comments
    This product is easy to install if you know what you are doing. You should have some background in electrical ampacity and wiring basics. I did have to purchase an additional pigtail.(flex tubing with 3 #10 color coded wires, and 1/2 connectors on each end about 5 feet total length) The heater had the wiring flex tubing direct from the wall to the top of the heater. The additional material was about 10.75 at the local hardware store. I unhooked the wiring from the heater and wired it to the timer, then wired the new pigtail to where I had disconnected the original wires. The timer has knockouts on the bottom for either 1/2 or 3/4 inch connectors so if it will accomodate either one. You most likely will have 1/2" connections. Make sure you turn off the breaker before you start. The entire process took about an hour total. The instructions that come with the timer aren't that great, so if you don't know what you are doing, it won't help much. The timer comes with 3 sets of on/off clips so you can time it on and off 3 times. We set it at on at 5 am, off at 8 am, then on at 8 pm off at 10 pm. So the timer is on 5 hours a day and off 19. We figgure we will save around 25 dollars a month off the electric bill. So... it will take at least 2 months to pay for the timer and other materials we bought. If you pay someone to install it, it will take much longer to pay for itself. So far, it is working properly and so I am satisfied.
