## Description

Never wait for hot water again. Watts Heat H2O Hot Water Recirculation System uses thermal bypass technology to provide hot water to your faucet or shower instantly. The device uses the pump in the water heater and a patented under the sink sensor valve, thermostatically controlled to create a pressure differential, allowing cold and cold water to pass to the cold water supply line at a low volume and keeps the water in the hot water supply line at a no-wait temperature throughout your home. Installs easily into existing pipes without the need for a return line or additional electricity under the sink, this quiet and efficient system requires no maintenance once installed and includes everything you need for a quick DIY installation: pump with 10ft cord, 2 adapters with rubber washers, sensor valve, mounting screws and two 12" supply lines. With the Watts Heat H2O Hot Water Recirculation System, your days of wasting time, water and money are over. The readily available hot water means no need to let the faucet work while waiting for it to heat up, leading 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 be activated only during peak hours of use. Its 24-hour dial features quarter-hour split tabs and AM/PM indications so you can easily set circulator operation according to your home's water usage patterns. Not designed for tankless water heaters. For indoor use only.

## Features

- INSTANT HOT WATER - Watts hot water recirculation system uses thermal bypass technology to instantly supply hot water in seconds on every faucet or shower when needed.

Not designed for tankless water heaters.

Includes everything you need for installation: heavy duty stainless steel pump head in aluminum housing, 10 foot cord, 2 adapters with rubber washers, valve mounting screws, and two 12" supply lines.
