Malcolm. I think we need a definition of Liquid petroleum gas as you
mention it. From my experience in heating the house and our food with
it -- the two names (propane and LPG) are interchangeable. I call the
lpg company to order a refill for the big tank outdoors and he brings
the stuff in a tanker truck labelled "propane". The guy pumps a
compressed liquid, but at ambient temperature, into the tank, and as
it flows through a regulator is gassifies into propane. To my
knowledge they're the same -- at least on this side of the Atlantic.
Would you be so kind as to enlighten me if there's a difference where
you are?
