    insulative value of soot?

    I have seen it written that soot on heat exchangers really insulate heat transfer to the water/steam.(with how important to brush these down) Anyone have any information on this? R value of say 1/32 inch of soot?

    I did some groovy math,..

    Based on 1500 gallons of oil burned per year, if you have your burner cleaned, removing 1/16th of an inch of soot you gain 4.5% efficiency, or you save 67.5 gallons of fuel.

    At $3.00 per gallon thats $202.50 Which completely paid for the annual maintenance, and possibly then some. So your saving money as well as having reduced downtime and no heat emergencies from proper filter changes and preventative maintenance.

    its nice to be able to put real numbers on the savings asa marketing tool.

    Thanks Ed!!

    To Mark & Norm,

    Glad to help.

    Norm, I have done the same math and you are right on point.

    It is indisputable that a properly adjusted and properly maintained oil heating unit simply saves money for the owner of that oil heating unit.

    Oil heating unit maintenance, done thoroughly and properly, is probably one of the best dollar for dollar investments (Return on investment) that they can make in this economy.
