Watts Hot Water Recirculation System with Programmable Timer for Tank Water Heaters, Instant Hot Water, 120V Pump, 10 ft Cord, 2 Adapters, Sensor Valve, Mounting Screws, 2 Supply Lines (0955800)

Three years ago we moved from a house that we custom built which included a recirc pump that provided hot water to all of our sinks within 5 seconds. It was nice to have that feature that we quickly took for granted. Although we didn't have to pay for water, as we were on a well, no one likes to waste water. Our current home was not built with a recirc system and although we are no longer on a well, we do have to pay for water and we try to conserve as much as possible. But we would have to start the shower and let it run for up to a minute until the hot water would finally start flowing. And that was the case in every sink and tub in the house.Our prior home's plumbing was built with a dedicated hot water return line loop, so I was skeptical of a recirc pump that supposedly worked with the existing piping without this extra line. But out of three years of frustration with our current situation we decided to buy this Watts recirc pump and give it a try.We have two hot water tanks so I installed it on the outlet of the second tank as instructed and installed the sensor valve that came with it under the bathroom sink the furthest away from the hot water tanks. It took me about two hours to install and get this pump and sensor unit operational from the time I shut off the hot water and drained a couple gallons of water off of the second tank until it was installed and operating. But it was two hours well spent as we now have hot water within 5 seconds throughout the house!Anyone with a basic understanding of plumbing can install this. The instructions are very concise and they provide everything you need except for a wrench and pipe thread tape. But if plumbing is not your thing, then buy this and have it installed. No more waiting and waiting and wasting water while the hot water finally makes it way through your home's piping until it finally gets to your sink, tub or shower.The pump itself is well-built and so quiet you can't hear it if you are standing next to it. You have to grab the outgoing water line and feel it to know the pump is running. And if you don't believe me, there are a whole lot of other great reviews out there that say the same thing. Personally, I am kicking myself as I should have done this 3 years ago.

I was really impressed with the Watts Heat H2O Hot Water Recirculation System. It’s a great product that does exactly what it claims—delivers hot water almost instantly without wasting time or water. The biggest highlight for me was how easy it was to install. I’m not a plumber by any means, but the instructions were clear and all the parts were included. I had it up and running in about an hour using basic tools.The programmable timer is a great feature. I set it to run during the times we usually need hot water, and it works flawlessly. Our bedroom shower is on the opposite end of the house from the water heater, and we used to wait forever for hot water. Now, the wait time has been cut by more than half—it makes a big difference in our morning routine.The included sensor valve and adapters made the whole process smooth. It’s also quiet when it runs, which was a nice surprise. Plus, the 3-year warranty gave me peace of mind.Overall, this system is a smart investment if you're tired of waiting for hot water. It’s efficient, easy to install, and adds real convenience. Highly recommended!

I can honestly say this is probably the most cost effective way of getting hot water to far places in a home, Our home 12 years old is roughly 3000 sq ft 2 story with 4 full baths with the master being at the most furthest point of the home upstairs roughly 100+ feet away from the hot water tank in the garage between the master bath sinks, jetted tub and shower I would have to wait almost 4 minutes of water running before it got warm then cold. The water lines used throughout the home are PEX non metallic plumbing. The pump and sensor unit are very easy to install on your own with a bit of common sense and took me about 40 minutes to install. I let the pump do it's thing for about 30 minutes went up to the 2nd sink in the master bath, which is the last and furthest in the home only 3 feet further than the 2nd sink, within approx 3 secs the water was warm to the touch followed by hotter water very shortly thereafter. I had my wife verify this later that evening, we would usually waste a bunch of water filling up the jetted tub or turning on the shower waiting on hot water, again within seconds the water was warm then hot!I was very amazed as I was getting prepared to drop a few thousand $$$ to have a Tankless installed just for the upstairs master bath I am very pleased with this system. Now I have seen where some people are concerned about cost to run this etc. first it waste no water so right there whatever the cost should be outweighed in water savings. Second I have seen people mock those about putting this on a smart timer since it already comes with a built in timer, what those doing the mocking are not realizing is that if the power goes out then the built in timer does not keep its correct time once power is restored, Yes I'm sure for many this is probably a very rare thing, but I can tell u you here in Northern CA the power especially in the summer is 50/50 at best! So yes I would highly suggest the use of a smart plug for one of these, I already have dozens of smart plugs/lights & switches in use at my home so I did not need to purchase one but they can be purchased for less than $25 I recommend Tp-link by Kasa! The other nice thing about the smart plug especially if it has the energy monitoring option (Not all do get one with the monitoring) is that you can get a real time look at what the power consumption is daily, weekly and yearly to kind of give you a idea of the Electric use which is not bad. The pump averages right around 22 watts +/- while running the company states is should be less than a nickle a day or so to run 24 hours. I may set up a schedule or Alexa routine but currently I have not having 48 345 watt solar panels and Battery I am not to concerned about 22 watts running.On to the gas usage, given we have a large home along with large heated pool/Jacuzzi and outdoor gas fireplace etc. we have a very large diameter gas line with a smart meter. I can always here the meter gurgling so to speak when any of the large items are being uses including the hot water tank, to date after checking numerous times I have yet to hear the gas meter or the actual hot water tank firing constantly, not saying it does not fire up once enough coldwater gets pushed back into it I am just not hearing it like a normal tank being heated up! So again I do not believe that the complaint of this using mass amount of utility to use 24/7 again as compared to dupping 100s of gallons a day down the drain I fully believe at best it is a gain in savings at worse it is a break even! I did have to purchase a second sensor kit to place in the kitchen downstairs as our home has a branched Hot water line since doing so even our kitchen sink water is now warm to hot within seconds. I have yet to experience the so called major bleedback into the cold water line that some have stated happens that when they turn on the cold water it is warm to hot for a brief moment, either way even if I did it is still worth every penny for this setup!
