The 320 Gallon Horizontal Above Ground Propane Tank is a new ASME vessel for a home that wants one supply for central heating, water heating and a handful of other appliances.
A licensed local installer we arrange sets the tank on a prepared pad, fits the regulator and gas line, and leak-tests every joint before handover. Save 5% on the tank and installation together.
256 gallons is 80% of this tank's 320-gallon capacity, the legal fill limit, at $2.67 per gallon. The tank still ships empty: a licensed local propane supplier fills it after it is installed and passes its leak check - usually a few days to two weeks after installation. The pre-fill leak check and account setup are free when you order the fill with your tank. Save 5% on the tank and fill together, or 10% with professional installation as well. How refueling works

Valves & fittings included
- Fill valve
- Double-check filler valve - the connection the delivery truck fills through. 250 gallons and up take the 1-3/4 inch ACME bulk-fill connection.
- Service / vapor withdrawal valve
- The vapor outlet your installer connects the first-stage regulator to.
- Pressure relief valve
- Required safety device. Vents to atmosphere if tank pressure rises above the set point, then reseats.
- Float gauge
- Dial gauge reading tank level as a percentage of capacity.
- Liquid withdrawal valve
- Draws liquid propane rather than vapor, for transfer and high-demand liquid service.
- Vapor return valve
- Returns vapor to the delivery vehicle during filling and relieves pressure back to another vessel.
Valves are factory-fitted to the vessel. The regulator, gas line and the propane itself are not included - a licensed installer connects the tank and a licensed supplier makes the first fill.
Home delivery - shipped by freight to your address
- Liftgate service is included on residential freight deliveries.
- Delivery is curbside: the driver brings it to the vehicle access point, not to the pad. Moving and setting the tank is installation work.
- The carrier calls the number on your order to book a delivery window, and someone must be there to receive it.
- Delivery is one flat rate, shown and charged at checkout - there is no separate freight invoice afterwards.
- Ships from the nearest of our nine US yards - in CT, NJ, PA, OH, MI, IL, MO and TX.
- Delivered anywhere in the 48 contiguous states.

About the 320 Gallon Horizontal Above Ground Propane Tank - ASME
The 320 Gallon Horizontal Above Ground Propane Tank is a new ASME vessel for a home that wants one supply for central heating, water heating and a handful of other appliances. It is about 40 inches in diameter and 9 feet long, weighs 620 lbs empty, and sits on the surface, so there is no excavation. Professional installation can be added for $1,150.
What it runs
Owners usually put a tank of this capacity behind whole-house service: a furnace or boiler, a water heater, a standby generator or a pool heater, with a range or dryer on the same line. The listing also places it in light commercial duty such as space heating, commercial kitchens, dry cleaning and crop drying. How long a fill lasts comes down to your appliances, your winters and how well the building holds heat, so have your propane supplier estimate your load before you commit. The propane tank size chart sets this capacity against the sizes either side of it.
Key specifications
- Water capacity: 320 gallons
- Outside diameter: 40 inches
- Overall length: 9 feet (108 inches)
- Head type: elliptical
- Empty weight: 620 lbs
- Orientation: horizontal, for above-ground use
- Built to ASME code
Above ground or buried
A surface tank skips the digging, so the site work is quicker and cheaper, and every valve stays in plain view for inspection. It also avoids the risk a buried tank carries of shifting or floating in waterlogged ground when it is not bedded on a firm base. The trade-off is appearance: the tank is visible, so choose a spot that a delivery hose can reach without crossing the whole yard. Distances from the house, property lines and ignition sources are set by fire code and your local authority; your installer sites the tank. If hiding it matters more, browse the underground propane tanks.
Common questions
Can it be filled as soon as it arrives? It ships empty and still under its factory vacuum seal. On the first visit your local propane provider breaks that seal by putting methanol through the POL valve, then fills it.
When should I order a refill? Lift the dome lid, read the float gauge, and call your supplier once it shows around 20 to 30 percent. Never let anyone fill it past the maximum safe level.
