Choosing tank capacity is driven by your real consumption. Residential properties use 120 to 500 gallon tanks, while commercial sites often require 1,000 to 2,000 gallon tanks. Space heating consumes much more than a cooktop, which is why undersizing results in running low in winter. Review the capacity guide before ordering.
Propane vessels are built to either an ASME or DOT rating, and distinction being important. ASME tanks are designed for stationary applications and these do not require recertification. DOT rated cylinders are portable though they require requalification periodically. Specifying the wrong type can fail inspection.
Setting up a propane tank goes beyond dropping it in the yard. Setback distances dictate the required distance away from your house, the property line and any ignition source. Rules change between municipalities and with vessel size. Surface installations require a level stable base, whereas buried tanks need proper excavation. Licensed installers handle see the propane tank size chart gas connection.
Buying factory direct eliminates the distributor margin which inflates prices through traditional retail. The price gap is often significant for commercial vessels. Direct supply also brings shorter lead times, as units are dispatched directly. New, used and refurbished options allow you to match budget to requirement.
Whether to choose above ground and underground installation generally depends on space, appearance and budget. Above ground installations are cheaper initially and are more accessible for repairs. Below-ground vessels are out of sight and offer protection from weather, though they require greater investment because of excavation and anode protection.
