The last thing you want to do is run out of propane in the middle of a camping trip. But determining how long your RV propane tank will last can be challenging due to various factors. For instance, if you’re in warmer temperatures, you won’t require as much propane to run your heater. Similarly, the amount of propane required for your hot water tank will depend on how frequently you take a shower.

Many traveling RV and motorhome enthusiasts will refill their tanks when below half; it just depends on how remote of an area you’re traveling to. If you’re interested in calculating your estimated propane usage, it’s not difficult. However, keep in mind that it’s just an estimate; so if possible, it’s always a good idea to have extra tanks or use dual tanks.

First, determine the size of your tank. RV propane tanks, like all propane tanks, are only filled to 80% capacity. If you’re filling an empty tank, you can see the gallons filled on your receipt.

Next, multiply the number of gallons in your tank by 91,502 (the number of BTUs per gallon of propane). You can find the BTU demands of your stove, water heater, and furnace in the owner’s manual or on a tag on the appliance. The BTU rating will differ from appliance to appliance.

Hours of Propane =

Total Gallons x 91,502 / Total BTU Requirement

Add the BTU demands together to obtain your total BTU requirement. Divide this number by your total BTUs, and you’ll know the number of hours of propane you’ll have for the appliances you calculated.Bear in mind that this can fluctuate since some appliances may be used more than others, but it’ll give you a rough idea of how long your propane will last in hours.
