Good news though, for most of us, bringing a standard 20lb tank is more than enough if heading out for the weekend! People tend to vary the height of their campfire flame depending on the weather and the number of people around it so it usually works out that you will get about 10 – 13 hours out of a 20 lb tank. A simple way to think about this is that the Campfire uses about 1 1/2 lb of propane per hour.
Most campfires will allow you to make the fire smaller but you can’t make the fire any larger than the maximum BTUs it was designed to generate. The size of the fire you want is typically determined by how many people are sitting around it, as well as the outside temperature.. or a combination of both. There are a lot of variables that go into this answer so you need some information to start with.
Formula to find burn time of a 20lb / 5.28 US gallon propane tank: US Gallon Propane tank capacity multiplied by propane BTUs per gallon = total tank BTUs 5.28 gallons X 91,502 BTUs = 483,130 BTUs Total campfire BTU burn rate divided into total tank BTUs = hours of continuous burn 45,000 BTUs divided into 483,130 BTUs = 10.7 hours. Pounds Propane tank capacity multiplied by propane BTUs per gallon = total tank BTUs 20 pounds X 24,156 BTUs = 483,130 BTUs Total campfire BTU burn rate divided into total tank BTUs = hours of continuous burn 45,000 BTUs divided into 483,130 BTUs = 10.7 hours
25,000 BTUs 35,000 BTUs 45,000 BTUs 55,000 BTUs 65,000 BTUs After taking all the above information and feedback from our customers you can usually expect 10 – 13 hours out of a 20lb / 5.28 gallon tank. *Note: The best course of action to take is to buy a campfire that does not limit how large or small your campfire can be, keep all your options open and enjoy your campfire.
