heat H2O Hot Water Recirculation System
Hot Water Recirculating Pump with built-in programmable timer
Why install heat H2O?
The Watts heat H20 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, saving up to 12,000 gallons of water per year.
How Does it Work?
This recirculating pump eliminates water waste caused by waiting for water to heat up. The device uses the pump at the water heater and a patented under-sink sensor valve to create a pressure differential. The pressure differential allows the cold and cool water in the hot water supply line to bypass into the cold water supply line at a low volume through the thermostatically controlled sensor valve, keeping the water in the hot water supply line at a "no-wait" temperature throughout the home.

The Watts heat H20 offers several benefits, including:
- Instant Hot Water: You get immediate hot water at your faucet or shower, eliminating the wait time typically associated with heating water.
- Water Conservation: The system can save a significant amount of water annually, as it prevents the wastage that occurs while waiting for water to heat up.
- Energy and Cost Savings: The savings may be substantial, as the system does help in reducing the energy consumption and will save money over the long term.
- Convenience: It provides a high level of convenience, especially in larger homes where the wait for hot water can be longer.
- Maintenance-Free: The pump is designed to operate quietly and requires minimal maintenance.
- Programmable Timer: It includes a programmable timer that allows you to set the pump to activate only when needed, or it can run 24 hours a day, depending on your preference.
Step 1 - Installing the Pump
A pump with a built-in timer mounts directly on the hot water line from the water heater with 3/4" connections.
Step 2 – Installing the Sensor Valve
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 98º, the valve closes.
Step 3 – Installing Sensor Valve Kits
If one section of your home does not receive hot water, you will need to purchase a Watts Sensor Valve Kit for each hot water loop. For best results, the valve should be located at the faucet furthest from the water heater in each loop.
INSTANT HOT WATER: The Watts Hot Water Recirculation System utilizes thermal bypass technology to instantly supply hot water in seconds at every faucet or shower when needed. The sensor valve opens when the water on the hot water side cools, pushes the cool water back to the water heater, and closes when hot water line hits 98°F. Not designed for tankless water heaters.
EASY DIY INSTALLATION: Operating on 120V, this quiet, efficient system easily installs into existing plumbing without the need for a return line or additional electricity under the sink, and once installed requires no maintenance. Includes everything you need for installation: heavy-duty stainless steel pump head in aluminum housing, 10 ft cord, 2 adapters with rubber washers, valve mounting screws, and two 12-inch supply lines.
WATER CONSERVATION: Your days of wasting time and water are over. With hot water available in 15 seconds, this convenient system can lead to significant water bill savings: up to 15,000 gallons per year.
CUSTOMIZABLE OPERATION: This pump 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.
