3.1 Introduction
All Grundfos Comfort Systems are carefully
inspected and tested before shipment in order to
ensure long, efficient, trouble-free service.
For maximum performance and reliability,
please follow the instructions in this manual.
A Grundfos Comfort System hot water
recirculation system is designed to bring hot
water in an instant to the hot water faucets in
your home.
Since the system utilizes the existing cold water
return line in the home, no separate new return
line is required. No electricity is required under
the sink.
The Grundfos Comfort System includes a
circulator pump that installs on the water heater
in your home, plus a valve that installs at the
furthest faucet.
The direction of flow moves from the water
heater through the recirculation pump, through
the hot water supply line, and then back to the
water heater through the existing cold water
return line.
