How Much Does It Cost to Fill a 20lb Propane Tank?

The cost to fill a 20lb propane tank typically ranges from $15 to $25, depending on factors like location, the current propane market price, and the vendor you choose. Prices can fluctuate significantly, so it’s always wise to shop around for the best deal.

Understanding the Cost of Propane: A Deep Dive

Propane, that seemingly ubiquitous fuel powering everything from backyard grills to RV refrigerators, isn’t priced in a vacuum. The cost to fill a 20lb tank is a dynamic figure influenced by a complex interplay of factors. To truly understand what you’re paying, let’s dissect the key components.

The Price of Propane Per Gallon: The Foundation

The most fundamental factor is the current price of propane per gallon. This price is volatile, responding to seasonal demand (think grilling season vs. winter heating needs), geopolitical events affecting energy markets, and even weather patterns impacting distribution. You can often find the average propane price per gallon in your area by checking online resources like the Energy Information Administration (EIA) website or by contacting local propane suppliers. A 20lb propane tank holds approximately 4.7 gallons of propane. So, if propane costs $3 per gallon, you’re looking at around $14.10 for the propane itself, before considering filling fees and taxes.

Filling vs. Exchange: A Critical Choice

You have two primary options when acquiring propane: refilling your existing tank or exchanging it for a pre-filled one. While exchange services are convenient and readily available at many gas stations and big-box stores, they often cost more per gallon. This premium is for the convenience and the assurance of a full tank. However, the tanks you receive in exchange may not always be completely full. Refilling your own tank, especially at a dedicated propane filling station, usually offers a lower price per gallon and guarantees you only pay for the propane you receive. You also ensure your tank is filled to its maximum capacity, which is typically around 80% to allow for expansion.

Location, Location, Location: The Geography Factor

Like real estate, the location of your propane supplier significantly impacts the price. Rural areas, where propane might be the primary heating source, can sometimes have higher prices due to increased demand and transportation costs. Metropolitan areas, while often having more competitive pricing, might be subject to higher overhead costs that get passed on to the consumer. Also, prices can vary greatly from state to state, depending on local regulations and taxes.

Taxes and Fees: The Hidden Costs

Don’t forget to factor in state and local taxes, as well as any filling fees charged by the vendor. These can add a significant percentage to the overall cost. Some places might charge a flat fee for the filling service, regardless of the amount of propane dispensed. Always ask about these fees upfront to avoid surprises.

Vendor Choice: Shopping Around Pays Off

Different vendors have different pricing strategies. Big-box stores often prioritize convenience and might charge a higher price per gallon for exchange services. Dedicated propane filling stations, local hardware stores, and even some gas stations might offer more competitive pricing for refilling. Shopping around and comparing prices is the best way to secure the most affordable option. Online price comparison tools, if available in your area, can also be helpful.

Making the Most of Your Propane Dollar: Practical Tips

• Monitor Propane Prices: Keep an eye on local propane prices and fill your tank when prices are lower, especially during off-peak seasons.
• Fill, Don’t Exchange (If Possible): Refilling is generally more cost-effective than exchanging.
• Check for Leaks: Regularly inspect your propane tank and connections for leaks to avoid wasting propane. A simple soapy water test can help identify leaks.
• Optimize Grill Usage: Avoid preheating your grill for extended periods and use it efficiently to conserve propane.
• Proper Tank Storage: Store your propane tank in a cool, dry place, away from direct sunlight and heat sources.
• Consider Tank Size: If you use propane frequently, consider investing in a larger tank. The cost per gallon typically decreases with larger volumes.

Frequently Asked Questions (FAQs)

Here are some frequently asked questions to further illuminate the world of propane and tank filling.

1. How do I know when my propane tank is empty?

The most obvious sign is when your appliance (grill, heater, etc.) stops working. You can also gauge the weight of the tank. A full 20lb propane tank weighs around 37 pounds, while an empty one weighs about 17 pounds. You can also purchase a propane tank gauge for a more accurate reading.

2. Is it safe to transport a full propane tank in my car?

Yes, but with precautions. Ensure the tank is securely upright, preferably in a well-ventilated area like the trunk. Avoid smoking or using any open flames while transporting propane. It’s best to transport the tank as directly as possible and avoid leaving it in a hot car for extended periods.

3. Can I refill a propane tank that’s expired?

No. Propane tanks have an expiration date stamped on the collar. Expired tanks must be recertified before they can be refilled. You can find certified facilities that can inspect and recertify your tank.

4. How often should I get my propane tank inspected?

Regular visual inspections are recommended before each use. Look for signs of rust, damage, or leaks. Professional inspections are typically required when recertifying an expired tank.

5. What is the difference between propane and butane?

Both are liquefied petroleum gases, but propane has a lower boiling point than butane. This makes propane more suitable for use in colder climates, as it can vaporize and fuel appliances even in freezing temperatures. Butane is more commonly used in lighters and portable stoves in warmer environments.

6. Is it cheaper to use propane or charcoal for grilling?

Propane is generally more cost-effective in the long run than charcoal. While charcoal might offer a unique smoky flavor, propane grills are easier to use, provide more consistent heat, and eliminate the need to constantly purchase charcoal.

7. Can I fill my propane tank myself?

While technically possible with the right equipment and knowledge, it is strongly discouraged and potentially illegal in many jurisdictions. It’s best to have your tank filled by a trained professional at a certified filling station to ensure safety and compliance with regulations.

8. What should I do if I smell propane?

If you smell propane, immediately extinguish any open flames or sources of ignition. Evacuate the area and contact your local fire department or propane supplier from a safe distance. Do not operate any electrical switches or appliances, as they could create a spark.

9. How long will a 20lb propane tank last?

This depends entirely on the appliance and its usage. A 20lb tank typically provides about 20 hours of grilling time on a medium-sized grill. High-demand appliances like space heaters will deplete the tank much faster.

10. What is the 80% rule for propane tanks?

Propane tanks are only filled to approximately 80% of their capacity to allow for expansion of the liquid propane due to temperature changes. This prevents over-pressurization and potential hazards.

11. Where can I find the best deals on propane?

Shop around! Check prices at local hardware stores, gas stations, dedicated propane filling stations, and even big-box retailers. Online searches for “propane refill near me” can also help you find nearby options.

12. Can I store a propane tank indoors?

No! Propane tanks should never be stored indoors, in basements, garages, or any enclosed space. They should be stored outdoors in a well-ventilated area, away from direct sunlight, heat sources, and potential ignition sources.
