Burner on Time

in Oil Heating
Just a simple (maybe) question. What is considered to be a long steady run? Five minutes? 10 minutes? Mine runs a average of 5-6 mins with a cal for heat and the circulator running. Is this too short?

This time of year shorter than dead of winter
Most oil boilers are oversized for the heating load since even a 3 section boiler (smallest oil boiler) is too big for an average insulated home. If there is hot water for showers, etc. the burner will run for longer.
Our 3 section Peerless WBV boiler has burner on times of between 5 and 10 minutes in the middle of the winter when we are not using the hot water. The house is about 2400 square feet on Long Island.0 -

buffer tank
coupled with a constant circulation loop and an ODR-controlled mixing valve can work well here.
A reverse indirect can be used in place of the buffer tank (with some loss of tank capacity due to the higher minimum temp.)0
