Recirculation Connections
H
Pipe domestic hot water supply piping
with tank as illustrated. Connections
must be accessible for service (use
factory supplied adaptors).
H
Install recirculation pump, flow check
valve and recirculation timer (for
shut-down during off-hours where
feasible) on the recirculation piping
side.
H
Gravity circulation of the recirculation
system is restricted due to the
upward-curved domestic hot water
discharge piping inside the tank.
H
Connect tank battery to existing
recirculation piping. Cap off unused
recirculation connections of individual
tanks.
H
Saving Energy
A timer on the recirculation pump
reduces the heat loss significantly in
commercial applications during times
when no or reduced demand for
domestic hot water occurs.
Connection of a recirculation system in a multiple tank installation
for systems utilizing boilers or remote heating plants
without low temperature boiler return water.
