Your LPG storage tank should have a gauge that shows you how much fuel it has in it. Most LPG suppliers suggest that you arrange a fuel delivery when the level in your tank gets down to about 20%. Make regular checks, particularly in the winter when you will use more, so you know when levels are low.
South Queensferry
Queensferry, likewise called South Queensferry or merely "The Ferry", is a community to the west of Edinburgh, Scotland, commonly a royal burgh of West Lothian. It exists 10 miles to the north-west of Edinburgh city centre, on the coast of the Firth of Forth in between the Forth Bridge, Forth Road Bridge and the Queensferry Crossing. The prefix South offers to identify it from North Queensferry, on the contrary shore of the Forth. Both communities acquire their name from the ferryboat solution developed by Queen Margaret in the 11th century, which remained to run at the community till 1964, when the Road Bridge was opened. Its population at the 2011 census was 9,026 based on the 2010 definition of the locality which along with the burgh consists of Dalmeny.
