I have a relatively new (7 years) oil-fired boiler with an aquasat
control that heats two zones and my domestic hotwater through the
I live in Maine (brrrrrrr)
I'd like to know what the most efficient hi and low setting are for
the aquasat. My furnace guy set them at 190 and 170 -- but I don't
trust him completely because he sells me my oil as well.
Are there any rules of thumb on this?
As a rule, I tend to trust the professionals, but in this case I'm
curious if there are others out there with different information.
