Smart Recirculation "On- Demand" Retrofit System
The Smart Recirculation Retrofit System is for homes that do not have a dedicated re-circulation loop.
The unit includes:
• a Grundfos pump
• stainless steel ball valve
• flow meter
• temperature sensor
• two control units (one built into the pump and one remote).
• wiring harness.
How the system works:
The main pump unit is installed at the furthest location in the plumbing from the water heater. This unit pumps water from the hot water line into the cold water line when water flow is detected and shuts off when the water is up to temperature.
The flow detector is installed at the water heater with the flow meter being installed at the cold water inlet and the temperature sensor is connected to the piping coming out of the water heater.
Give yourself the gift of hot water when you need it!
These units are built to order so please allow 2 weeks for shipping.
