- Have you often wondered why your propane is running out so quickly?? Or maybe you just want to know if you have enough propane to get through a week of RVing? If you want to find out EXACTLY how to calculate how long your propane will last, then this video is for you! Don't be stuck out in the cold without heat! Let Ian Baker teach YOU how to ensure you'll have enough propane for every trip or adventure you take.

Finally, somebody who can tell me a non-guessing and objective way to calculate how much propane do I need!
Thank you very much, that was very helpful!
Glad it was helpful!
Glad to hear it helped!
Ian your one great guy!
Thanks Mark, I appreciate it! Let me know if there is something you’d like to see a video on and I’ll try to work it in!

That was great! Thanks
Thank you very much, I always appreciate feedback!

Thanks for explaining it now I have a better idea how fast I might use the propane.
My pleasure!! I thought it was interesting and I'm glad others do too!

How long it lasts depends on what you use. The biggest offender from our standpoint is the furnace. The water heater and fridge when traveling sip it. When we lost power last February and it was 0 degrees and we slept with the generator running we burned up our entire tank in one night.
All I would use is my rv furnace at 75 degrees.with a 40 pound propane tank.will it last 3 days.it would only run 10 hours a day.
Heres a real world example: (Could I have a leak?) I have a 1999 Admiral Hloday Rambler 30ft Motorhome in really good cond. It was lived in 4 a while by the prev owner/bush pilot, so everything works. I just filled up the empty 25gal(170lb) tank at $3.57/gal/propane. In N AZ with a temp range of 18-50° over the past week, the tank's empty(also running hot/cold water in all sinks/shower to avoid busted pipes). I'm thinking I've got a massive leak. A guy here in YT many seem to agree with said in the dead of winter single digit temps,he averages 30lbs over 6 days with furnace running almost constantly. . But then I'm finding others claiming 30lbs in one day but no examples. SO WHICH IS IT? I've never been a fan of propane bcuz it's way to overpriced,& it's an added thing on top of the electric that's already required to run the furnace blower, appliances, etc..A good back up if your rich. I'm poor. I'd have much rather spent that $100.00 on better electric heaters/blowers, pipe heat tape, etc., than light it in fire, 4 overpriced dinosaur farts. That was my last $100.00 too..Sunuva##$%

Run electric heaters when u can
Wrong. A 20lb propane tank should have 20lbs of propane in it. That is what it is designed to hold. The tank's internal volume exceeds 4.7 gallons by about 20%. In other words, if somehow you overcame the overfill valve, and tried to fill it up to the valve, you could (in theory) fill it with about 24lbs of LP. However. many exchange services rely upon this confusion and only fill the tanks with 15lb of LP and market it as a "20lb tank". Several companies were fined by Missouri for misleading consumers this way.
If you don't believe me, refill your tank and weigh it. Subtract the tare weight (which can vary by several pounds) and you should be right around 20lb.
Hi There! I apologize for the delay in getting back to you, as I was reaching out to our technical institute to get a more comprehensive answer/response.
You're correct that a 20-pound tank should have 20 pounds of propane in it.
DOT portable containers are calculated at 80% full already, no further mathematical hoops to jump through.
ASME containers permanently installed in motorhomes are labeled at 100% full and the technician must multiply by .8 to calculate the fill capacity.
The BTU/hr, BTU/lb, and BTU/gal statements in the video are all correct. That said, it is not helpful to subtract the BTU/hr inputs from other appliances as it doesn’t translate into actual LP savings.
When calculating how much LP will fit in a container, you must choose a method. NFPA 1192 states that only 2 methods are legal: volumetric and weight. Since we cannot weigh an ASME tank on a motorhome, we must use the volumetric method.
This means we open the 80% fixed maximum liquid level gauge and stop filling when we see white liquid come out. We use both when filling a DOT cylinder. First, know that propane expands and contracts a lot with small changes in temperatures, 1.5% for every 10 degF up or down.
Water is comparatively stable and this is why we use water capacity as a reference point for container capacity. Next, know that propane has 42% of the mass of water, so we multiply the water capacity by .42.
For example: WC 47.7 x .42=20lbs. 20 lbs + TW18.7= 39 lbs scale weight.
So when filling the cylinder, we know it is correctly filled when any one of these happens: the scale trips, white liquid comes from the 80% fixed maximum liquid level gauge, or the overfill prevention device valve closes at 80%.
When we use the generic weight of a cylinder (20lb, 30lb, 40lb), we take a risk we teach our students to never take: assuming the actual weights of a container. We absolutely must read the data off of the container and perform the math each time we fill it because accuracy counts when it comes to propane safety.
At Camping World, we charge for the actual amount of LP dispensed, just like getting gasoline in your car at the gas station.
Other providers often charge by the container regardless of the actual amount of LP dispensed.
Hope all this helps, but please let us know if you have follow up questions!

@@campingworld Now that's a great reply! Thanks!
Pretty much 17 hours max the your screwed. Propane is too expensive basically to live in an RV.
Hey Amy, Ian Baker here. It honestly depends on the usage. If it's the middle of winter in Minnesota and you don't have dual pane windows or your RV doesn't have great insulation, then yes, you will most certainly go through propane in a hurry. However, there are a lot of people who live in an RV full time and manage it just fine. This is part of the reason "snow birds" are so common. You won't use nearly as much propane if you travel south during the cold months. I agree with the fact that propane can be pricey though! Thanks for watching Amy!

You're completely wrong. 30lb or 7 gallons lasts 3 weeks for me when in RV. I also use a buddy heater in winter on a 5 gallon tank also about 3+ weeks. Furnace I don't use it sucks power not propane
