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?
