INSTANT HOT WATER SYSTEM
AS LITTLE AS 14 WATTS!
Get instant hot water at every
faucet with as little as 14 watts!
How autocirc Works
The autocirc is the most efcient system, turning on only when the system needs to be
replenished with hot water. The pump is installed under the sink farthest from the water
heater where hot water takes the longest to arrive. No recirculation line is required.
Design
The autocirc has a spherical motor. The only
moving part of the pump is a spherical rotor/
impeller unit which is suspended on a wear
resistant ceramic ball. Laing pumps are
completely shaft-less. The patented, Laing
design eliminates problem shafts, seals and
cylindrical bearings found on conventional,
mechanically sealed canned pumps.
Hot water will also be instantly available at all
other faucets located on the hot water supply
line between the water heater and the faucet
where the autocirc is installed.
Fixed Thermostat Models
• A built-in temperature sensor automatically
turns the pump ON when water temperature
in the hot water line cools down to 85°F. Water
is then pumped from the hot to cold line. The
autocirc pump turns OFF automatically when
water temperature reaches 95°F, ensuring
instant availability of shower warm water with
maximum temperature hot water only seconds
behind. When the pump is OFF, a built-in auto
closure device prevents any other hot-to-cold
line or cold-to-hot line mix.
Adjustable Thermostat Models
• For models with the adjustable thermostat,
there is an adjustable “ON” temperature range
from 77ºF to 91ºF (25ºC to 33ºC). This built-in
temperature sensor will turn the circulator OFF
when it reaches 95ºF (35ºC) and turn the circulator
ON when the temperature cools down to the
“ON” temperature set point.
