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
• control units (one built into the pump and one remote).
How the system works:
The main pump unit is installed at the furthest location in the plumbing from the water heater. This then pumps water from the hot water line into the cold water line when waterflow is detected and shuts off when the water is up to temperature.
The flow detector is installed at the cold water input to the water heater 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!
