They look the same and they both create
a pressure differential
to move liquids, but the difference becomes obvious when you look at the application. irrigation system, it must have enough pressure to operate the irrigation system. A circulator is used to move water in a hydronic heating or cooling system.
What is the function of the circulator pump?
A circulator pump or circulating pump is a specific type of pump

a water pump that moves hot water around your heating system
. The water travels from your boiler through to the pipes that feed your radiators, towel rails, and hot water cylinder. The water then flows back to the boiler to maintain a constant flow of heated water around your home.
What turns on a circulator pump?
In the U.S. some areas a hydronic heating system is wired so that the thermostat simply turns the circulator pump on – ostensibly to
move hot water from the boiler to the heated area
. In turn it’s the temperature of the water in the system that, monitored by the boilers aquastat, turns the burner on and off.
What does a Taco cartridge circulator do?
The Taco 007 is a cartridge style, maintenance free, wet-rotor, in-line, single stage circulator. It is designed for
quiet operation in Hydronic Heating, Radiant Heating, Hydro-Air Fan Coils, Indirect Water Heating, Chilled Water cooling, and Domestic Water Systems
.
How do I know if my circulator pump is working?
a simple quick test on the circ pump is
to carefully touch the motor housing
. When operating normally it should feel quit warm. Too warm to hold on to. You will also feel the vibration from the running motor.
Does a recirculation pump increase pressure?
If a fixture is opened to flow water, the pressure in the line is instantly lowered. Pressure is the energy that moves water through the piping. … Hence, in a recirculating system,
the hot water being pumped through the piping always tends to have a higher pressure than the return line to which it connects
.
How do you bleed air from a circulating pump?
- Step 1 – Turn off the power. …
- Step 2 – Protect against water damage. …
- Step 3 – Turn off the water at the shut-off and gat valve. …
- Step 4 – Slowly remove the pump bleed screw. …
- Step 5 – Mop up all the water that trickles out of the pump. …
- Step 6 – Screw the bleed screw back into place. …
- Step 7 – Turn on the power.

The pump of your central heating system can last a long time if it is properly installed and maintained. Typically, they keep going for
at least 10 years
.
Should my circulator pump be hot?
Feel the Hot Water Heat Piping at the Circulator Pump
The most common way to see if the circulator pump is having issues is to touch it. It doesn’t matter which side you feel; it
should be warm or slightly hot when running
.
How big of a circulator pump do I need?
Every 10,000 BTU’s of heat load the circulator must output a
1 gallon per minute flow
. The minimum flow rate for a circulator pump should be 10 gallons per minute at a pressure drop.
How much does it cost to replace circulator pump?
Replacing a failed circulator pump can cost as little as
$400
or as much as $750 or more for the parts and labor at the time of publication. Cost of just the circulator pump itself falls in the range of $100 to $300 depending on the model your system needs.
