Why does the circulator run in the heating zone?
The heating zone is air-bound so heat doesn’t reach the thermostat for that zone: the thermostat calls for heat and is never satisfied and the circulator runs continuously
How many zones does a circulator pump have?
It has three zones. All three circulator pumps, which are on the return pipes by the boiler, seem to be running, based on the sound they are making, and the motors on all of them are quite hot, while the pipe part of the pump is cold, as is the rest of the piping except for the first couple of feet exiting the boiler.
Why does hot water run even when the circulator is off?
Jared, usually the problem you describe is traced to a check valve malfunction at the heating boiler or at the circulator pump (depending on what equipment is installed). Hot water can circulate by natural convection (warm water rises in pipes, cold water falls) even when the circulator is off.
Why does a circulator run continuously in a house?
The circulator was deliberately-wired to run continuously, as is the custom in some heating zones such as much of Canada. This is done to reduce the risk of frozen heating pipes and to keep heat distribution more-even in the building.
