An oversized boiler will do this because it makes more steam than the system can condense. I have a boiler that is rated for 271sqft EDR. My system has 260sqft of EDR. From observing my system over the past 3 years it always run between 20 to 25 minutes on a call for heat. Never have observed it cycle on pressure.
