A 20 lb propane tank will cost approximately $14-$20 to fill. The rate you pay depends on the refill cost, usually $3- $4 per gallon. Since a 20 lb tank holds about 4.7 gallons of propane, multiply the cost of propane per gallon by 4.7. For example, $3 X 4.7 = $14.10.
The cost to refill a propane tank varies from $3.00 - $4.00 a gallon at most U-Haul propane refill locations. On average, you will be spending $1.76 less per gallon by refilling your propane tank rather than exchanging it. That's more money in your pocket to fill up your propane tank on your next visit!
Buying a propane tank starts around $5, with a high of $3,500 and an average around $800 to $1,000.
How Much Does it Cost To Fill a 100 Lb Propane Tank on Average?
| Size | Cost |
|---|
| 20 lbs. | $40 |
| 100 Gallons | $500 |
| 500 Gallons | $1,500 |
| 1,000 Gallons | $2,500 |
This means a “full†propane tank should weigh about 37 pounds.
The decision about propane tank exchange vs refill is less about what is the better option, and more a matter of convenience vs price. So, is it cheaper to exchange a propane tank or refill it? The short answer is refilling is cheaper.
How to Make Your Propane Last Longer
- Turn your thermostat down by 10 to 15 percent, and shut off your heat when you are not at home.
- Keep the intake vent and air filter in your home clean.
- Use a grill with an automatic ignition.
- Upgrade your equipment.
- Cook smaller portions of food.
In general, a newer RV refrigerator with around 10 to 12 cubic feet of internal volume will consume around 1.5 pounds of propane per day. This translates into roughly 1,400 BTUs per hour.
A typical RV furnace would use between 20,000 and 40,000.A 20lb tank of propane will provide @ 432000 BTU hours. So running constantly, a 20000 BTU furnace would go through a 20lb tank of propane in about 22 hours.
The average-sized RV furnace will burn about 1/3 of a gallon of propane while running continuously for an hour. Based on this estimate, a gallon of propane = 3 hours of continuous RV furnace use.
As a rule of thumb, one tank of propane will typically last between 18-20 hours if you're grilling on a medium-sized grill. Whereas larger grills can burn through 20-pounds of propane in as little as 10 hours.
To measure how many pounds of propane are left in your tank, simply weigh it on a scale and subtract the TW number. For example, if a tank weighing 27 pounds has a TW of 17 pounds, there's about 10 pounds of gas left – a little more than half a tank.
Sometimes, the easiest way to tell if your propane tank is empty is to try lighting your grill. When there's fuel in the tank, you'll be able to get a flame. But if it's empty, the grill won't light. You can also listen for sounds coming from the fuel line.
“While both gasoline and diesel fuel degrade with time, propane never goes bad,†he said. “It won't degrade through any natural process like it can with other fuels. Gone are the days of running your gas tank to empty before storing it for the winter.
An empty propane tank is practically breeding ground for air and moisture to enter, causing rust build-up inside of your tank. Not only is this permanent, but also then masks the propane odor, making it more difficult to detect a leak or when something else has gone haywire with your tank.
The easiest way to tell how much propane is left in a 100 lb tank is to purchase a propane gauge simply. If this is not possible, then you have a few other options to do so without one. Alternatively, you can check the level with hot water or by testing the weight of the propane tank.
Most grilling tanks weigh about 17 pounds when empty and hold about 20 pounds of gas. To measure how many pounds of propane are left in your tank, simply weigh it on a scale and subtract the TW number.
A 100-pound propane cylinder is heavy and should be loaded carefully and with the help of another person. If transported on its side, the cylinder may roll and shift the pressure relief valve to the bottom, in the liquid space of the cylinder.
Propane Tank Transportation-Safety Tips
NEVER keep a filled propane cylinder inside a hot vehicle. ALWAYS transport a cylinder in a secure, upright position so it will not fall, shift, or roll when you're driving. ALWAYS close the cylinder valve. Seal it with a plug if required—even if the cylinder is empty.Propane is explosive and propane can explode but a propane-LPG tank explosion is actually very rare. Propane tanks (gas cylinders) can explode but not easily or often. It is actually really hard to have a propane tank explode.
Never take a propane tank indoors. Never leave your propane tank in your vehicle. If your propane tank is left or stored in your vehicle, heat, sunlight and motion can increase pressure to an unsafe level creating a flammable, explosive environment.
When Transporting Cylinders
- Disconnect cylinders and plug or cap all outlets before you go.
- Always carry the cylinder in an upright position with the safety valve on top.
- Never put a propane cylinder in a closed vehicle.
- Secure the cylinder in the upright position so it can't tip over while you're driving.
To dispose of smaller tanks that are damaged or unserviceable, contact a propane supplier, or your local household hazardous waste collection site. Some municipalities or local regulations may allow for disposal of empty propane tanks, propane cylinders, and propane bottles with your regular household trash.
After production, propane is transported in liquid form by pipelines to a central distribution plant, where it is stored in large steel cylinders and tanks. From there it is transported by trains, trucks, barges, or ships to “bulk plants.†One gallon of propane in LPG form contains 84,250 Btu of energy.
