I don't know why few stores carry this and few people are aware of this great product, including those sales persons in home improvement stores. It gives instant warm water to all the rooms in your house, it saves 10,000 gallons water a year (really, I measured and calculated) and it is so easy to install.

Doubt about if it really works? Try this: go to the farthest faucet in your house and open the hot water. Once the water becomes hot, close it, but not fully, leaving a very small stream. Now go to other faucets and open hot water, you bet, instant hot water! It'll keep this way as long as you keep that small stream flowing.

The problem is that small stream goes wasted. How about recycle it into the hot water heater? Sure, but how? The hot and cold water lines have the same pressure, therefore water cannot go from the hot line into the cold line. What if I add a pump into the hot line? Exactly, that's what this Watts product does. Problem solved.

For a practical and fine product, Watts also add a temperature sensor, so the recirculation only happens when the hot line becomes not so warm. This, plus the stream is really small, adds very small extra energy cost to the heater.

The pump is very small, only 25 watts, using less electricity than a lighting bulb. There is also a 24-hr timer (in 15-minutes increments), allowing you to shut the entire system off during the periods when you do not use warm water, such as sleep and work times. This reduces even further the already very small added energy cost. BTW, the pump is thoroughly quiet, no audible noise at all.

An alternative product is the Laing Autocirc. It is a single piece can all be installed under a sink, could be a better choice for some people.

I bought the Watts Premier hot water recirculating system and let me tell you it works great! I did not notice my gas (heating) bill going up significantly at all. It was well worth the investment as far as I am concerned for convenience and saving water.
The only negative thing I can say about it is that the remote stop valve did fail. There was not a whole lot of information about this problem with this system to be found, even on the internet, so I didn't know what was going wrong at first. But slowly it seemed like there was a lot of hot water on the cold side when we turned the cold water on. It was more and more as time went on. And the valve became noisy and sounded like water was going through it all the time. I finally called Watts customer service. After being on hold for a half and hour, I talked to a rep who confirmed to me that the stop valve was failing. They were willing to send me a replacement, but I had to either send the old one back first or pay for one and get a credit after I sent the old one back. They said they are very strict about this because there is only a one year warranty on the valve and people were always calling in trying to get a free replacement after the valve failed or get extra valves when needed.
Because he didn't sound very concerned, I then asked if this was a common problem and he admitted then that YES the valves do inevitably fail. It could be 6 months or a year or two years, three years.... who knows? But they do fail and it's just a matter of time. They really aren't made to last very long. But they are made to last at least a year- long enough to expire the warranty period.
They don't tell you that when you buy it, of course and it doesn't say it in the manual.

We purchased this product to try to be more "green" about our water usage. While the product should be able to do what it states, it is going back tomorrow. After installing it, we were getting hot water in the cold water line (despite running the valve test they recommend in the manual). After waiting on hold for awhile, I reached someone who explained that if we had single handled faucets from any of a few manufactures the system would not work. They explained that these faucets would let water flow from the hot to the cold side when the pressure was raised on the hot water supply (which is how this system works). The only fix is to replace a part in the faucet (if available) or replace the faucet. Since this affects six faucets in our house that are too old to get new parts, we are done. I have no problem with this restriction, but it is not listed ANYWHERE, including their web site and instructions. Given that I now have a piece missing from my hot water supply line, it is a little late to tell me now. I give the product an `A' for what it will do, but I give the company an `F' for their documentation and lack of disclosure of a major problem. This is too major (and common) and issue to not tell people about up-front. I feel mislead by Watts.

I installed the Watts recirculating pump November '07, along with under sink mix valve kit in the kitchen. I bought an extra valve kit for the master bathroom sink. The pump timer was set for the busiest times of day. There was a nearly immediate improvement in hot water at both faucets, which was glorious! The cold water side runs warmer, but so what? But the story gets more interesting:

Being an engineer I was always a bit curious why the pump was necessary, since a law of thermodynamics states that heat always flows toward cold. Theoretically, the mix valves under the sinks ought to function without the pump. Well, one day I unplugged the timer to see what would happen. You know what? The faucets produced hot water just as fast without the pump running! Now we leave the pump off all the time. My advice is to save yourselves money and just purchase the undersink valve kits (about $50 each). The pump can always be added later if you find it's still necessary. Maybe some water systems require the pump. Hope this helps!
