The
Check Valve Method: Options
A and B shown at the right are examples of
the Check Valve Method.
The
Check Valve Method utilizes the existing
standard home plumbing system. Clicking on
each diagram will enlarge different components
of the system so you can see how they work
together to heat the water and bring it to
each spigot.
The
Command System is designed to move hot water
from the hot water heater to your most remote
fixture within your home. At the push of
the command button, or at the set of a time
clock the cold water you normally let run
down the drain is recirculated back through
the cold water lines as hot water is filling
the hot water lines to your faucet. When
the hot water arrives at the hot/cold exchange
valve the system automatically shuts off.
The
Return Line Method: The
Dedicated Return Line Method, shown in Option
C, negates the need for a hot/cold interchange
to be installed under the sink, but requires
additional pipe to be installed from the
furthest sink to the hot water heater. This addition
can be quite expensive when considering
not only the pipe itself but repair of the
walls afterward.This
line may already have been installed in some
newer homes as they were being built.
In
options B and C, a small motor is
placed at the hot water heater unit.
The motor may be controlled by a
remote control capability, such as
is used with an automatic garage
door, or by continual ON and OFF
settings of a time clock. Either
the remote control or the time clock
provides the actual turn ON and OFF
of the water pump assembly.
