Hey!! Wait a minute there Spacely Sprockets! I'm not THAT old! ;-)

Keep in mind 33,479bth is one Boiler HP _output_. That's why one
500HP will steam like another (different brand/eff. rating )500HP.
So depending on burner eff. and if the manufacturer is using a nominal
5 sq.ft. per hp, the btu input can vary. (Older boilers looked much
larger because they were,,, rated @7-10 sq.ft. per HP.)
But yes, HP can get quite twisted sometimes.
