Burning wood and coal in a Harmon 250 and pressure is at 35psi @ 190 degrees. Talked to a reeeeeeeeeaaaaaal knowledgable guy who says I need a bigger in-line pressure tank. Period. Wood/Coal boiler tied into oil boiler with five gall. tank not big enough. Been trying to burn coal, and can't keep it going with aquastat set at 180. If I turn it up I pop my cap because of pressure. Some say 180 aquastat good enough, others say not-so-much. Any thoughts appreciated.
