| Appliance | Typical input | Duty cue | Daily BTU cue |
|---|---|---|---|
| RV furnace | 16,000 to 40,000 BTU/hr | 5% to 60% of day | Weather drives the result most. |
| Absorption fridge | 1,000 to 2,200 BTU/hr | Cycles across 24 hr | Often 15,000 to 45,000 BTU/day. |
| Water heater | 8,800 to 12,000 BTU/hr | 15 to 90 min/day | Showers and dishes raise burn. |
| Cooktop burner | 5,000 to 9,000 BTU/hr each | 15 to 90 min/day | Total active burners matter. |

💡Propane Planning Tips
Propane availability require that you understand in what length of time your propane supply will decrease while you are on the road. Many traveler find that their propane supplies will decrease quick while on the road due to the operation of appliances that use propane, such as the furnace taking longer to run while camping through the night, taking more longer showers, or the refrigerator running while propane is being used. Beyond considering propane level in your propane tank alone, you should also consider the length of the night that you will have propane to support your camping appliances.
Each of your appliance will contribute to the propane use that you will experience daily. For instance, the furnace will not necessarily run at its full capacity while you are on the road; instead, the furnace will cycle on and off according to the outside temperature, the wind, and how well your RV retain heat. Appliances like the stove will use propane in short burst, but appliances like the refrigerator will run continuous.
How Long Will Your Propane Last While Camping
Additionally, water heater will use propane according to the number of showers and number of dish that are washed daily. Each of these factor will contribute to the daily propane burn that you experience, and each of these factor will reduce your available number of day that you can enjoy your vacation with propane that is supplied by your propane tank. You can use a propane calculator to determine the number of days that you will have propane based off the size of your propane tank, the amount of propane that you currently have, the amount of propane that you would like to leave in your tank as a reserve, and your daily propane burn rate.
Additionally, weather factor in the amount of propane that is used; for instance, if the outside temperature drop, the furnace will need to run longer to heat your RV. The same is true for altitude; at higher altitude, the propane appliance will not run as efficiently. Both of these factor is considered in the calculator, but you will need to know the altitude at which you will be camping and the weather forecast to make certain that you accurately enter these factor into the calculator.
Another factor to consider prior to travel is the amount of propane to leave in your tank as a reserve. Some traveler may choose to reserve 15-20% of their propane tank as a reserve to ensure they dont run out of propane while traveling. While some may use their propane reserve to cover travel day in addition to potential emergency, both of these use of propane are valid.
It is essential that you enter the amount of propane that you plan to leave as a reserve in your tank in the calculator, rather than an estimated amount. Common mistake when estimating propane use for travel is to either consider the propane tank gauge to determine propane use; however, the gauge indication may not accurately represent the amount of propane in the tank. Additionally, travelers may only consider the propane use of the appliances that use the most propane, such as the furnace.
While the refrigerator will use propane each and every day while camping, the amount of propane that the refrigerator uses daily is small but contribute to the total amount of propane that will be used each week. Each of these factor can be entered into the calculator to determine the total number of days that you can travel on the propane that you have in your tank prior to needing to refill it. The value of calculating propane use prior to departure on a camping trip is in the fact that you will no longer have to guess at the length of time until the propane that you have in your tank will be use up.
Additionally, you will be certain of the number of day that you will have propane for camping, as well as when you will need to refill the propane tank for the next portion of your trip. This information will eliminate the worry associated with propane use while on the road.
