Bubba, the recirculator pump, usualy a B&G moves the water through the
system to Heat more evenly then old gravity systems. A common retrofit
50 - 60 yrs ago. If aqua stat is set say at 140 but house thermostat is
still calling for heat the pump will just run till water gets to say 135
then refiring the boiler. Pump stuts off when house thermostst is
satisfied.

Ransley,
I know EXACTLY what it is. Ive only been in this for 25ish years now.
Third generation actually. It is NOT called a recirculator. It is
called a B&G CIRCULATOR pump motor. There is no RE in it.
I also havent seen any REFIRING. I usually watch boilers FIRE. Again,
no RE.
Pump doesnt shut off if the house thermostat satisfies when you are
using a aquastat to control the pump. It will shut off when the water
is somewhere below 140 degrees. That aquastat can also be wired in
several different ways. I can even use a Tekmar control on the boiler
and not even use an indoor thermostat.
Do you need any more help now?
