INSTALLATION OPTIONS
In an existing home - The D’MAND® System is designed
to move the hot water from your water heater to your most remote fixture (kitchen,
master bath, stc.) within seconds. At the push of a button, the cool water you
normally let run down the drain is circulated back to the water heater through
the cold water line. The D’MAND® System is easily installed under the sink farthest
from your water heater. At your D’MAND®, the pump pulls the hot water from the
water heater moving only the cold water back through the cold water line into
the water heater to replace the hot water being moved. When the hot water arrives
at The D’MAND® System it is automatically shut off by a thermo sensor at a 3 to
5 degree temperature change.

In a new home - There are two options for Structured
Plumbing, both using the S-Series Metlund D’MAND® System. The first option is
to locate the S-Series pump and the thermo sensor at the fixture furthest from
the water heater. The second option is to locate the S-Series pump at the water
heater and extend the thermo sensor from the electronic control board back to
the fixture furthest from the water heater. Both options can be activated by hand
with buttons, remote wireless buttons or motion sensor. Both the S-Series pump
and the thermo sensor should be installed on the dedicated return line pipe. When
hot water is demanded, using any of our activation methods, the Metlund D’MAND®
System brings hot water rapidly to the farthest fixture from the water heater
where the sensor will pick up the temperature rise and send a signal to turn the
pump off. This concept prevents the hot water passing the thermo sensor, thus
saving lost energy in the dedicated return line.
