Propane Tanks

Propane Tanks for Sale – Buy ASME and DOT Certified Tanks

Whether you are heating a house through the winter, running a farm, or keeping a standby generator fueled, the tank is the part of the system you buy once every few decades. This category holds our full range of propane tanks for sale, from 24-gallon Manchester cylinders up to 2,000-gallon ASME vessels, in both above ground and underground configurations. Every tank is certified and inspected before it leaves the yard, and every order ships nationwide on flat-rate freight.

Choosing the right size

Size is the decision people get wrong most often, usually by buying small to save money and then paying for it in delivery minimums and winter run-outs. A 120-gallon tank suits a single appliance such as a range or a dryer. A 250 to 330-gallon tank covers a small home with a couple of gas appliances. The 500-gallon class is the common choice for whole-home heating, and 1,000 gallons and up serves large homes, farms, and standby generator loads. Remember that tanks fill to 80 percent, so a 500-gallon tank holds about 400 gallons of usable propane. Our guide to what size propane tank you need walks through the BTU math.

ASME or DOT, above ground or underground

Stationary tanks are built to the ASME Boiler and Pressure Vessel Code and filled on site by a delivery truck. Portable DOT cylinders are taken to a filling station and must be requalified on a federal schedule. If you are not sure which one your application calls for, read ASME vs DOT propane tanks before ordering. Placement matters too: underground tanks free up your yard and hold steadier vapor pressure in cold weather, but they need excavation, a riser, and an anode bag for corrosion protection. We compare both in above ground vs underground propane tanks.

Finding the Right Propane Tank Size

Sizing comes down to how many appliances the tank feeds and how often you want to refill. A 120- or 250-gallon tank covers a home with one or two propane appliances, say a range and a fireplace. The 500-gallon tank is our steady best seller because it handles whole-home heating, a water heater, and a pool without needing constant top-offs. Move up to 1,000 gallons and you are into large homes, farms, and light commercial demand, where buying propane in volume during the off-season is part of the appeal.

One rule holds across every size: a tank fills to about 80% of its rated capacity, leaving room for the liquid to expand in the heat. A 500-gallon tank gives you roughly 400 usable gallons, and that is the number to plan your winter around, not the label. As a rough guide, a filled 500-gallon tank can carry an average home through most of a heating season before it needs a refill, though your mileage depends on climate, insulation, and how many appliances you run. The larger the tank, the fewer delivery visits you schedule and the more room you have to buy propane when summer prices dip. That is why plenty of buyers who could get by on a 500 choose the 1,000-gallon instead.

Small Tanks and Portable Cylinders

Not every job needs a stationary tank. For cabins, food trucks, forklifts, and grill setups, a portable cylinder is the practical choice. Our 100-pound ASME Manchester tank ships with a multi-valve and gauge and suits a low-demand appliance or two. If you need something rated for transport rather than a fixed install, the 200-pound DOT propane tank is built to be filled, moved, and refilled without a permanent connection.

Above-Ground vs. Underground Tanks

This is the question we field most, and there is no universally correct answer, only trade-offs. Above-ground tanks cost less to install, sit ready for inspection, and are easier to monitor and service. You will see the tank in the yard, which some people mind and some do not. Our 1,000-gallon above-ground tank is a straightforward pick for a rural property where looks take a back seat to easy access.

Underground tanks disappear from view and shrug off freezing weather, since the surrounding earth insulates the propane. The catch is excavation, a proper foundation, and a bit more care against a tank shifting or floating if the site is not settled right. A 1,000-gallon underground tank with riser keeps the regulator and gauges reachable while the vessel itself stays buried. If curb appeal matters or you are tight on usable yard, underground usually wins despite the higher install cost.

What ASME and DOT Actually Mean

You will see both ratings across our tanks, and the difference is simple once it clicks. DOT tanks are portable cylinders, built to be transported, filled at a depot, and moved again. ASME tanks are made for permanent installation and stay where they are set. A 100-pound cylinder for a grill is DOT territory; a 500-gallon tank feeding your furnace is ASME. Buy for how the tank will live, because using the wrong type for the job creates headaches at inspection and refill time.

Propane is a safe, clean-burning fuel when the equipment is sound and installed correctly, but it deserves respect. Stationary tanks should be sited, connected, and leak-tested by a licensed professional in line with NFPA 58 and your local code. We supply the certified tank and its paperwork; the install belongs to a qualified technician.
