Hi,
Is it better to have a one line system or two line system on the typical
oil burner (line going to the head and to the tank). I read that a two
line system pumps more oil then is needed to fire and the rest is sent
back to the tank. I also read that a one line system is better for not
rustling up the sludge on the bottom of the oil tank? Are there pros and
cons for both? I read that the big guys are going away from two line
systems because if the line breaks you could pump a lot of oil into your
boiler room.

It all depends on the installation. A two pipe system can lift higher
and will allow longer oil lines. A single pipe system will need manual
purging of the oil pump if run out of oil, a two pipe system will not
need manual purging. I don't think rustling up the sludge is an issue.
It is true that if the return line breaks you can pump out oil, but in
the same token if a single pipe line breaks and the tank is above the
pump, the oil will flow out or siphon out also. I think the likely
hood of any line breaking is remote, leaks usually occur at the
fittings, pipes don't break if installed correctly and are not damaged.

A single pipe system requires half the copper and fittings, I suspect
this could be a consideration for some.
