One gallon of propane will produce 91,600 Btu's. One gallon of
kerosene will produce 134,000 Btu's of energy when burned, which
makes it similar to diesel or gasoline.
I don't know how long kerosene will keep.
Does anyone have experience?
So far, I like propane because there is no issue of shelf life. With
gas or diesel, one needs to add conditioners and worry about
condensation.
'Course, we homesteaders all like wood as we can produce it and it is
a renewable. But its Btu rating does deteriorate with age. So when I
am 102 and dropping trees and swinging a splitting maul is becoming
onerous, those stacks between the yard trees are losing it every day
and I am unlikely to feel much like replenishment beyond another brew
or three.
