What is Smart Recirculation Control?
Smart Hot Water Recirculating Pump Controller
This controller turns any home or business plumbing system with a dedicated circulating line, tank water heater, and hot water circulating pump into an on-demand hot water system.
- Works with tank and tankless water heaters
- For use on systems with a dedicated recirculation loop
- Implements "Smart Timers" that automatically disable when no flow is sensed for 24 hours
- Proudly designed and made in the U.S.A.
- See real time flow and temperature values via "Live Date"
- Program and monitor with a smart phone app for Android and iPhone
Turns any recirculation pump into an on-demand recirculation pump.
- Flow-based hot water pump controller.
- Unique dual temperature sensor design.
- Reduces pump run time to less a couple hours a day. **
- Includes built-in pump timer capability.
- Easily configure with your Android or iPhone smart device.
The Smart Recirculation Control is an On-Demand smart hot water recirculating pump controller for homes with a dedicated recirculation loop (if you don’t have a dedicated recirculation loop check out our Smart Thermostatic Control). This control works with tank and tankless water heaters. If you have a Navien combi unit check out our Smart Aquastat Control.
The Smart Recirculation Control controller is designed to sense when hot water is drawn from any plumbing fixture and to run the recirculation pump until the water in the recirculation loop is hot.
The microprocessor-based design monitors the temperature of the water in the loop using a unique dual temperature sensor design to ensure the water in the loop stays hot while hot water is being used.
On-Demand Operation
To operate go to any faucet and turn the hot water on then off. The Smart Recirculation Control senses this minimal draw, checks the water temperature in the loop, and if necessary, starts the pump running. Within seconds the water loop is hot and you are able to draw hot water.
Because the Smart Recirculation Control uses the demand of hot water to know when to run the pump, it works even when your washing machine or dishwasher needs hot water. Unlike other on-demand hot water systems, there is no need to install switches or sensors at each faucet location and run wires, maintain wireless transceivers, or replace batteries.
Smart Timers and Vacation Mode
The Smart Recirculation Control also has a set of “Smart Timers” that can be used to heat the recirculation loop on a schedule. But because of the dual temperature sensor design, the Smart Recirculation Control only runs the pump until the loop is heated up.
The “Smart Timers” are disabled if the controller doesn’t sense a hot water draw within 24 hours. So if you go on vacation and forget to manually disable them, no worries, they will turn themselves off and re-enable as soon as it senses a hot water draw. The “Smart Timers” are set via your Android or iPhone smart device. The on-demand functionality is still in effect outside of the timers.
The Smart Recirculation Control is all you need to efficiently control your hot water pump. Because of the dual temperature sensor design, it doesn’t matter what temperature is set on your water heater, it uses the difference to know when to turn the pump on and off. Flow meter sensitivity and temperature difference settings are easily set with your Android or iPhone smart device.
The Smart Recirculation Control Helps Save Your Plumbing.
Running a recirculation pump continuously will accelerate the erosion of the copper piping in your home causing pin-hole leaks requiring replacement of the entire hot water supply system and water damage to your home. This is no small expense.
The Smart Recirculation Control helps avoid this expense by turning your recirculation pump into an on-demand hot water system. Running a pump “on demand” typically reduces pump run time to less than 45 minutes a day!
Start saving water ($), energy ($$), and your plumbing ($$$) by installing Smart Recirculation Control!
Smart Recirculation Control works with all 110/220 VAC makes and models of pumps up to 1/2 hp. Our Smart Recirculation Control family of products is made with a Type B plug and socket. Other plug and socket types will require an adapter appropriate for your country.

Very easy to connect and get running. Easily connected to the app to configure, monitor, and manually trigger. My only issue was that the unit is not sealed and one connection develop a leak which dripped on the unit and shorted it out. Just be sure to position it accordingly to avoid this and you’ll be fine. On the plus side, Dave at Leridian was very responsive and helpful and got me back up and running ver quickly. Great customer service like this is not easy to find!
Added benefit: Guests who may not be aware of the system can turn the hot water on and the recirc pump will shorten the time for the hot water to reach the faucet since it is pulling cold water into the return line, thus still saving some cold water from waste. An unaware guest with a push button system would waste all of the cold water. Down side: With single handle faucets it is common to have some hot water flow even when getting a glass of water because many people leave their handles centered. That eats up some electrons with the pump running and does cause some water to be heated that will sit in the pipes slowly losing heat.
Excellent product that simply works well. The price is a little high, but I don’t think there is a comparable product on the market.
