500-Gallon propane tanks

This tank’s moderate size offers an ideal balance between capacity and convenience. Our standard above-ground 500-Gallon propane tank measures approximately:

• Length: 9.5 feet (114 inches)
• Diameter: 37.5 inches
• Requires a horizontal footprint of 10 feet by 4 feet, including clearances.

Underground models have similar dimensions but need additional excavation space

An empty 500-Gallon tank weighs about 950-1,150 pounds. When filled to maximum capacity, it holds around 1,520 pounds of propane bringing the total weight to 2,470-2,670 pounds.

It’s important to note that tanks are filled to 80% capacity for safety reasons, meaning they actually hold about 400 gallons. Given the weight, professional installation and solid surface reinforcement are required.

The amount of time a full 500-Gallon propane tank lasts varies depending on usage:

• 3-6 months on average for households using 2-3 propane appliances.
• 2-3 months in cold weather when homes rely on propane heating
• 4-6 months in mild climates or when only using propane for specific appliances.

We recommend customers schedule a refill when the gauge reads 20-30% to maintain uninterrupted service.

A 500-Gallon propane tank maintains internal pressure of approximately 125-175 psi at average temperatures (60-70°F).

The pressure in a propane tank will naturally fluctuate - increasing during hot weather (200+ psi on very hot days) and decreasing during cold weather (below 100 psi in freezing conditions).

All our tanks have pressure relief valves that activate if pressure exceeds safe limits.

A 500-Gallon tank must be installed at least 10 feet from any buildings, property lines, and ignition sources to comply with NFPA 58 safety standards.

Above-ground tanks require a solid level surface like a concrete pad, while underground tank installation involves excavation and backfilling.

Professional installation is mandatory to ensure proper pressure testing, leak checking and connection.
