Whether to choose above ground and ShopPropaneTanks underground propane tanks generally depends on space, appearance and budget. Above ground installations carry a lower price initially and more accessible for repairs. Buried tanks are out of sight and provide better temperature stability, but cost more because of digging and corrosion protection.
Propane tanks are built to either an ASME or DOT rating, and distinction being important. ASME tanks are built for permanent installation and are not subject to requalification. Portable DOT tanks are designed to be moved though they must be requalified periodically. Getting this wrong can fail inspection.
Going factory direct eliminates the middleman and this inflates prices at local suppliers. The price gap can be substantial on 500 and 1,000 gallon units. Ordering direct usually gives shorter lead times, since units are dispatched directly. New, reconditioned and used vessels allow you to match budget to requirement.
Setting up a propane tank involves more than dropping it in the yard. Required clearances govern how far the tank must sit from buildings, property lines and ignition sources. Requirements differ by jurisdiction and by the size of the tank. Surface installations call for a level stable base, and below-ground installations need proper excavation. Licensed installers handle the gas connection.
Sizing a propane tank depends on your real consumption. Most homes use between 120 and 500 gallons, whereas larger operations typically need 1,000 gallons or more. Space heating draws far more than cooking alone, so choosing a smaller tank means more deliveries. Check the size chart ahead of purchase.
