I just got two quotes to upgrade by oil fired steam boiler burner, and one recommended the Riello F-3 burner, with BTU outputs ranging 70,000 to 133,000 the other vendor recommened the Riello F-5 with BTU outputs ranging from 105,000 to 210,000.

How did they come up with two different choices and which is the correct one ?

My current boiler is a Dunkirk # 717, and the Oil Fired ratings are as follows.

Net IBR Rating
Steam Sq. Feet = 430

Max Firing Rate 17 lbs., 1.60 Gallons.

I have calculated the actual steam square footage, by adding up the radiator sections in my home, and the actual steam square footage is 240 square feet, not including piping.

The current burner is a Sun Ray, Model DSP, from 1965.

Any recommendations ? Thanks in advance.

    I would go with the F 5

    The F5 has a maximum firing rate of 1.50 GPH, while the F3 has a max of .95 GPH. The F5 falls a little short of the max your boiler needs , but not many companies will run a boiler at its maximum .
