Without the recirculating pump, getting hot water to our upstairs master bathroom could take up to 5 minutes of running faucets or the shower. After about 6 weeks of having this in place, I have to say that I am very happy with it. I have the timer set to come on between 5:00 and 11:00 AM and 5:00 and 11:00 PM -- but I also have it alternating to be on for 15 minutes and then off for 15 minutes during those times. So far, I have yet to wait more than a few seconds for hot water. I haven't seen a full month water bill with the pump but the water savings should be significant. I had a friend who is a plumber help me install it, but realized that it would have been fairly easy for me to do myself. I saw a couple of reviews complain about having warmer water coming from the cold side of the faucet. The pump works by moving colder water in the hot line back to the water heater through the cold side. Consequently, if the hot water faucet has not been used for a while, the cold side will be less cold than usual for the first few seconds, after which it will return to the normal cold-water temperature fairly quickly. The bottom line is that it is a reasonably minor inconvenience that is more than offset by the benefits. Along with the cost savings, just being able to wash you hands with warm water, or to get directly into a hot shower on a cold morning without having a long wait definitely makes it worthwhile.
