In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
Can you help? Boiler switches on and off intermittently.
I am a homeowner and not a heating professional. I'd gratefully appreciate any feedback about this.
The heat and hot water all work fine. But sometimes the boiler will switch on and then off almost immediately.
The boiler is a cast iron Peerless. The house is a bi-level ranch. Heat is baseboard. It has 4 zones: one on lower floor, two upstairs, plus hot water.
I have been unable to determine if the problem is zone-specific, but I don't think it is.
I called Peerless they thought it might be the hot water getting "topped off." This doesn't make sense because sometimes the boiler will switch on and off only about ten minutes apart.
My plumber switched out the aquastats for the three zones. We also changed the hot water min/max.
The problem remains.
A big shout out to Dan Holohan for his great books and wonderful site.
