Propane Tanks 101

Everything you need to know about choosing, maintaining, and understanding propane tanks — whether you're new to propane or just want to be better informed.

Types of Propane Tanks

Above-Ground Tanks: Most common for residential use. Easier to install and maintain.
Underground Tanks: Hidden from view and ideal for aesthetic or space concerns. Require proper drainage and corrosion protection.
Cylinder Tanks: Portable tanks used for BBQs, patio heaters, and small appliances.
ASME vs DOT Tanks: ASME tanks are stationary and do not require recertification. DOT cylinders are portable and need periodic recertification.

Common Tank Sizes

120 Gallon: Ideal for single appliances (like water heaters or fireplaces).
250 Gallon: Best for small homes using multiple propane appliances.
500 Gallon: Perfect for whole-home heating and appliance use.
100 Gallon+: Used for large homes, commercial properties, or high-usage needs like generators or heating greenhouses.

Tank Placement Guidelines

120-500 Gallon Tanks: Must be at least 10 feet from buildings, property lines, and ignition sources.
Underground Tanks: Require excavation and cathodic protection systems to prevent corrosion.
Level Ground: All tanks must sit on stable, level surfaces — usually a concrete pad or blocks.
Access for Delivery: Ensure there’s safe access for our delivery truck, even in winter.

Tank Maintenance & Safety

Inspect your tank visually for rust, dents, or shifted footing after storms or deep freezes.
Keep snow, ice, and debris cleared from valves and regulators.
Never paint over warning labels or safety decals.
Schedule regular leak checks (required if service is interrupted or tank runs out).
We handle all maintenance and safety inspections on leased tanks — just give us a call.

Choosing the Right Size

Choosing the right propane tank depends on a few key factors:

Home Size: Bigger homes with multiple appliances typically need larger tanks.
Appliance Use: Are you heating your whole home or just running a fireplace?
Refill Frequency: Larger tanks mean fewer deliveries — important in remote or snowy areas.
Aesthetics & Zoning: Underground tanks may be preferred for visual or HOA reasons.
