I've been wondering- with these units, what happens to the nasties
that're in the used oil? Metals, sludge and toxins. Where
do they go when you use the oil for heat? Up the stack and
into the atmosphere, or is there a filter that keeps
the worst bits from getting burnt? Then, what do you
do with the leftovers?
