What is a circulator boiler?
What is a circulator boiler?
Heating circulator pumps or “zone circulators” are used to force hot water from the heating boiler through radianting devices such as hot water baseboards or radiators. The circulator is switched on as needed or in some designs may be wired to run continuously.
What controls a circulator pump?
The low switch indirectly controls the heating circulator by locking out (keeping off) the circulator pump assembly if the boiler temperature drops into the low range. Check valves control circulator flow or flow rate and may be used to balance heating zone flow or heat output.
How much does a circulator cost for a boiler?
Boiler Pump Replacement Price A boiler circulator pump costs $250 to $1,000 for materials and labor. It’s a common problem for these to fail over time as they’re one of the only moving parts. But they’re usually covered under warranty.

What can a circulator relay do for a boiler?
Any expandable switching relay can also interface with the Boiler Reset Control and Injection Mixing Add-On Power Controls. • 2 zones single throw with end switch for boiler • 110 Volts • for Circulating Pumps
Which is the most common control of a boiler?
The aquastat is the most common control of heating system boilers. On a call for heat the thermostat, connected to the aquastat primary control, will operate a circulator control relay inside the aquastat to turn on the circulator pump, or on some systems the thermostat may be connected to a separate circulator relay discussed just below.
How are circulator pumps used to control heating?
Circulator relays on heating boilers – an older and by some heating service technicians, a preferred method to control the distribution of heat to individual building areas uses a individual circulator pump to force heating water through each individual heating zone piping.
