## Description

Never wait for hot water again. The Watts Heat H2O Hot Water Recirculation System utilizes thermal bypass technology to provide hot water to your faucet or shower instantly. The device uses the pump at the water heater and a patented under-sink, thermostatically controlled sensor valve to create a pressure differential, allowing cool and cold water to bypass into the cold water supply line at a low volume and keeping the water in the hot water supply line at a no-wait temperature throughout your entire home.Easily installed into existing plumbing without the need for a return line or additional electricity under the sink, this quiet, efficient system requires no maintenance once installed and includes everything you need for quick DIY installation: pump with 10 ft cord, 2 adapters with rubber washers, sensor valve, mounting screws, and two 12-inch supply lines.With Watts Heat H2O Hot Water Recirculation System, your days of wasting time, water, and money are over. Readily available hot water means no need to let the tap run while waiting for it to heat up, which leads to significant water and money savings: up to 12,000 gallons per year and up to 10% off your water bill!This pump also includes a convenient built-in programmable timer that can be set to run for 24 hours a day or to activate only during peak use times. Its 24-hour dial features quarter-hour division tabs and AM/PM indications so you can easily set operation of the circulator according to your household's water usage patterns.Not designed for tankless water heaters. For indoor use only.

Review: Excellent Product, Easy Install - I just installed this after buying in September 2025. It took me about an hour to get it fully installed. It runs silent and works very well. I was able to get hot water at most area's of my home in under 5-seconds. Considering getting an additional "sensor" valve to speed up one other section. I was worried about cost of electricity overtime but I used an AI agent and it resolved the math for me. Average cost was $1 to $3 monthly in eletricity based on response. I thought it would be significantly more to run continuously. One note, instructions mention to use pipe dope on the hose connection going to house from pump (but not tank to pump). I think thats easy to overlook. I had to go back and redo it as I initially overlooked.
Review: Instant Hot Water and Easy DIY Install – Great Product! - 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!

### ⭐⭐⭐⭐⭐ Well worth the money and SO easy to install.
*by R***R on May 19, 2024*

After years of waiting for water to reach the far areas of my house, I had finally had enough. This pump exceeded my expectations and works flawlessly. It sat on my counter for a few weeks until I finally decided to install it. Installation time was less than 30 min. It took me longer to get the junk out from beneath the far sink than it did to install. The instructions are straight forward and easy to understand. I did the under the sink valve first. They supply you with all the right hoses and connections. I did have to get long hoses, but that is not the fault of the mfg. My supply pipes are further apart. I bought longer hoses and everything was golden. Installing the pump was beyond easy. Yes I did have to buy the correct CPVC fittings with 3/4" threads to connect to the pump. Less than a dollar at the local hardware. Off the discharge pump I went with a flexible hose that connected to my system. You will have to buy a few extra pvc fittings if you need to make it work with your water heater system. It took less than 30 min to install in total and I plugged it in. I could tell it was working, but the pump is extremely quiet. We set the mode to timer, because we want it on from early morning to around 11 pm at night then the timer shuts off the pump. You will still have hot water, but just not as fast as when the pump is working. Even if you let it run all the time, it would cost around $20 a year, tops, but the timer is a nice feature. So far I am extremely happy with the product and it has hot water at our furthest sink within 5 seconds. Don't hesitate to buy this product.
