The Watts instant hot water recirculating system brings convenience and savings to your home, giving you hot water instantly at every faucet or shower when you need it. This unique product connects easily to existing plumbing. It saves up to 15000 gal of water per year and up to 10% of your water bill. An average home has 125 ft of 3/4 in pipe. 125 ft of 3/4 in pipe holds 3.14 gal of water. If hot water is used 10 times per day, 31 gal of water is wasted running the faucets/shower to get hot water. In a year, this equals to 11461 gal of water. 25.2 million homes waste approximately 300 billion gallons of water annually. A pump with a built-in timer is installed on the hot water line from the water heater. A patented sensor valve opens when the water on the hot water side cools and pushes the cool water back to the water heater. As the temperature in the hot water line hits 98 deg, the valve closes. Some homes are designed with multiple hot water loops, one per floor. If one section of the house does not receive hot water, you will need to purchase a Watts sensor valve kit for each loop. For best results, the valve should be located at the faucet furthest from the water heater in each loop.
