From small cylinders for a backyard barbecue to behemoths for business use, propane tank sizes differ significantly, as do their prices and uses. With costs set by tank size, installation type, and extra services, buying the right tank is more than a spontaneous trip to the hardware store. The guide below breaks down all you need to know, from cost and details to where you’ll get the best deals in 2025. Whether you are a homeowner, farmer, or business owner, we’ve got your back when it comes to propane.
Regardless of whether you’re fueling a grill or warming an entire house, propane tank prices differ significantly depending on size and installation method. For your planning purposes, here’s a step-by-step breakdown.
Grill-sized cylinders (15–20 lb) tend to be in the $35 to $60 bracket, while larger portable models (e.g., 100 lb) can be around $150. Perfect for occasional usage such as BBQs, portable heaters, or compact camping setup, most of them are pre-filled or even with exchange points for a slight added convenience.
They are suited for small houses or RVs. Installation cost is between $400 and $1,200, depending on whether it’s above or below ground. They offer limited home heating or cooking needs and are generally chosen for cabins or weekend cottages. Propane delivery is normally scheduled monthly or bi-monthly.
This is the typical size for whole-house heating and runs $700–$3,000 when installed above ground, with owners paying approximately $1,400 in total. It’s the largest standard home size due to its balance of capacity and refill cycle, ideal for families that use propane twelve months a year. Underground installation increases lifespan and curb appeal.
Ideal for larger homes or small farms. Above-ground installations cost $1,500–$3,000; underground installations cost $2,500–$5,500. Perfect for residential with pools, generators, or appliances running simultaneously. Also more effective on repeated refills, hence best for high-usage properties.
Used in industrial or agricultural settings. Installation prices vary $11,000 to upwards of $80,000 depending on site complexity and tank size. Tanks are usually custom-installed with protection devices and service agreements. They provide the manufacturing, greenhouse, or fleet fueling businesses.
Leasing tanks typically costs $50–$200 yearly and includes maintenance, while buying yields long-term cost savings and vendor leeway. Leases are best for short-term needs or for customers wanting convenient service. Ownership is better for controlling refill cost and vendor choice.
Buying a propane tank isn’t just about size, it’s also about placement, materials, labor, and added services. Know the hidden costs before you commit.
As would be expected, the bigger the tank, the more costly it is. Steel tanks cost more than composite tanks, especially at larger capacities. Composite tanks are lighter and corrosion-resistant but less common in large dimensions. Steel remains the norm for pressure resistance and strength.
Above-ground installations cost between $400 and $3,500 and buried tanks cost between $1,500 and $5,500 because of excavation and piping charges. Underground tanks are more time-consuming and need permits but are hidden from sight and less weather-exposed. Above-ground tanks are simpler to install and maintain.
Labor is between a few hundred dollars and a few thousand dollars depending on permitting, trenching, and gas line installation. Bumpy terrain, rocky terrain, or frost line problems may contribute time and expense. Local ordinance may also affect overall project schedules.
Permit fees usually cost between $25 and $150. Underground tanks can be subject to annual inspections which cost between $50–$75. Some safety inspections, especially for high-capacity tanks or neighborhood areas with more stringent zoning restrictions, can be required by local municipalities or fire departments.
Addition of concrete pad ($50–$175), gas line installation ($15–$25/ft), and old tank removal ($100–$1,500) are added on. Suppliers bundle such services for convenience for some, and bill them separately for others. It is wise to include these while factoring to avoid surprise bills later.
Ownership provides market flexibility and long-term savings; leasing is easy setup, low maintenance, but restricts provider choice and can have minimum usage contracts. Buying is ideal for homeowners who plan to remain in the home long-term. Leases suit rented properties or brief businesses.
Stores like Home Depot/Walmart offer bare or pre-filled propane tanks—usually AmeriGas or Flame King tanks. Refillable 20 lb tank prices usually range from $40–$70. Tank exchanges and restricted refill locations can be found in these stores as well. Their advantage is being close by and having longer return periods.
Full-service packages are offered by local providers: installation, tank, delivery tracking, and refill contracts. Popular choices include Ferrellgas, AmeriGas, and local co-ops. Local sellers tend to have improved refilling prices and quicker customer support. They are capable of offering in-home installations under rent-to-own schemes.
Retailers like Flame King and Manchester Propane offer tanks directly online ranging from small portable 10 lb cylinders to mid-range 100 lb ones sold for $30–$800 based on size and coming with certification included. Direct buying ensures warranty protection and compliance with regulations. Some models come with additional accessories like gauges or valve kits.
These stores service portable tanks for mobile use. They deal in DOT-approved tanks for mobility and safety. Massive with outdoor clubs, these locations provide light-weight and stackable configurations ideal for grills, heaters, and trailers.
Tractor Supply-type retailers sell mid-cap tanks with exchange or refilling on the premises, ideal for rural and farm customers. They’re also a source for installation parts, regulators, and hoses. Prices are comparable, especially for quantity or repeat business.
Industrial energy suppliers with large capacity tanks and installation, as well as contractual delivery and servicing options, cater to commercial use. They provide businesses with long-term fueling options that offer continuous energy supply. They are equipped with telemetry systems that enable automated refilling.
How much a propane tank costs is more than up-front price, it’s about considering lifetime cost, tank longevity, safety, and fuel savings. Most homeowners pay between $600 and $2,500 total for residential tank installation, with an average of roughly $1,400, according to industry data. Renting might be suitable for low-volume or short-term uses, but purchasing offers more value over the long term. Ensure your tank is DOT certified and adhere to local zoning laws, and schedule regular inspections when buried.
When deciding where to buy a propane tank, consider your long-term needs. HomeDepot/Tractor Supply offer convenient choices for small sizes, while local propane dealers offer full-service solutions such as tank size recommendations, installation, and refill schedules. Online manufacturers offer competitive prices for do-it-yourself clients. For bulk or industrial need, specialty distributors offer capacity to fill demand with flexible delivery terms.
