    how much does soot insulate?

    I think I remember hearing that xxxx thickness of soot equaled a 1/2 or inch of fiberglass insulation. I don't remember exactly OR if its true but I was very impressed that it was important to keep yer boiler heat exchangers clean.
    Anyone know? AND

    If you had a boiler that burned 2,000 gals of oil, would you do a mid season brush down?

    A lot! Why would you tolerate an oilburner that produced soot in the first place?

    nine percent

    I once read that an eight inch of soot reduces heat transfer by nine percent. Now soot is carbon, unburned fuel. Another thing I see form is sulphur, scale, and ash the percentage that affects heat transfer I don't know. A properly tuned burner that doesn't goof up (anything mechanical can goof up)does not make soot. (not referring to early burners still in service) Using prepurge and clean cut pumps on oil burners makes a difference. Proper piping for the particular installation can affect ash and scale by it's affect on the flue gasses condensing. If a burner stays warm or if it is used for an indirect water heater year round all affect how clean things stay. Different brand burners burn better in different boilers than others. But if a burner is "properly" serviced once a year it should run to it's full potential.

    ssot value

    My old school notes tell me that 1/8" of soot has equivilant R value of 1" of fiberglass. That what I have used for years.
