The effects of an always-on circulator assembly installation are more even heat and in some cases perhaps improved freeze-resistance for the heating system piping. So depending on where you live and how your heating system is designed and controlled, it may be normal for the circulator pump(s) to run continuously.
Do hot water recirculating pumps run continuously?
While the system is capable of running continuously, it doesn’t always do this. Most hot water recirculating pumps come with sensors or timers to regulate operation.
