What kinds of businesses use commercial propane delivery?

The most common commercial propane accounts are: warehouses and distribution centers (forklift cylinder exchange), restaurants and food trucks (cooking and water heating), construction sites (temporary heat for drying drywall, curing concrete, and worker comfort), greenhouses (heating and CO₂ enrichment), and any rural commercial building without natural-gas service. Propane also runs auxiliary systems like backup generators at hospitals, data centers, and cell-tower sites.

What is forklift propane cylinder exchange?

Forklift cylinders (typically 33 lb steel cylinders) are too small to refill on-site economically and too heavy to handle frequently in a working facility. The standard arrangement is cylinder exchange: the propane supplier maintains a cage at your facility with full cylinders, and a route truck swaps empties for fulls on a fixed cadence (weekly is typical). Pricing is per cylinder; the supplier owns the cylinders and is responsible for re-qualification and inspection.

Do restaurants need a permit to install a propane tank?

Yes — commercial propane installations are subject to building, fire, and mechanical code review. The Authority Having Jurisdiction (AHJ) — typically the local fire marshal — issues the permit, inspects the installation, and signs off before fuel is connected. Permit requirements, setbacks, and tank placement rules differ from residential and from state to state. Your propane supplier handles permit submission for most commercial installs.

How quickly can a commercial propane account be set up?

For an existing tank or cylinder cage, a same-week start is typical once you sign a service agreement. For a new bulk tank installation requiring excavation, permitting, and inspection, plan on 2–6 weeks depending on AHJ turnaround and weather. Construction temporary-heat accounts (skid tank delivered to the job site) can usually be set up in a week.

Are there volume discounts for commercial propane?

Yes — commercial pricing is typically tiered by annual gallons, with the steepest break above ~10,000 gal/year. Most suppliers will negotiate a fixed per-gallon rate or a posted-rate-minus-discount agreement for accounts above a certain volume. Multi-site accounts (chains, contractors with multiple job sites) can usually consolidate into a single agreement.

Commercial Propane Delivery: Forklifts, Restaurants, Construction, and Heat

How commercial propane delivery works for forklift cylinder exchange, restaurant kitchens, construction temporary heat, and bulk-tank business heating — plus what to ask a supplier.

Commercial propane covers everything from a single forklift cylinder cage at a small warehouse to multi-site auto-delivery across a chain of restaurants. The fuel is the same — LP-gas — but the service model, billing, and delivery cadence differ enough from residential that it is worth understanding the categories before requesting quotes.

Common commercial propane categories

Category	Typical setup	Delivery pattern
Forklift cylinder exchange	33 lb cylinders in a cage	Weekly route swap
Restaurant cooking	250–500 gal bulk tank	Monthly auto-fill
Temporary construction heat	Skid tanks (250 gal, mobile)	Job-site delivery as needed
Greenhouse heat / CO₂	Bulk tank, often 1,000+ gal	Heating-season auto-fill
Backup generator	Buried tank, 500–2,000 gal	Annual top-off + post-event refill
Off-grid commercial heating	500–2,000 gal bulk	Auto-delivery, winter cadence

The cleanest divide is between cylinder service (forklifts, food trucks, small kitchens) and bulk delivery (everything with a permanent on-site tank). Cylinder service is priced per cylinder and cycle; bulk delivery is priced per gallon at delivery.

What changes vs. residential

Commercial accounts differ from residential in three meaningful ways:

Pricing tiers. Posted residential per-gallon rates rarely apply;
most suppliers offer a posted-rate-minus-discount or a fixed
contract rate based on projected annual gallons.
Delivery SLAs. Commercial customers typically negotiate an
uptime SLA — for example, a guaranteed refill within 24 or 48 hours
of an order, with credit if missed. Auto-delivery customers expect
the supplier's degree-day modeling to keep them above their reorder
point.
Documentation and permitting. Commercial installs require AHJ
plan review and approval before construction:

“Plans for new installations shall be submitted to the authority having jurisdiction prior to installation. The authority having jurisdiction shall approve plans for installation prior to construction.”
NFPA 58, Chapter 15 (Operations and Maintenance, 2024 ed.). View source

The supplier typically pulls the permit, files schematics, and coordinates the post-install inspection on behalf of the customer.

Forklift cylinder service in detail

Forklift propane is its own product category. The standard cylinder is 33 lb steel (or 43 lb for heavier-duty applications), with a specialized fuel coupler and a vertical-orientation requirement on the truck. The supplier maintains a cylinder cage on your property — a fenced, ventilated outdoor enclosure — and a route truck swaps empties for full cylinders on a fixed cadence. Cylinders remain the supplier's property; you pay per fill and per cylinder rental.

Re-qualification (visual + hydrostatic inspection) of forklift cylinders is a federal DOT/PHMSA requirement; a cylinder past its re-qualification date cannot legally be filled and shipped:

“Each specification cylinder that becomes due for periodic requalification, as specified in this section, must not be filled with a hazardous material and offered for transportation or transported until the cylinder has been requalified or replaced.”
US DOT / PHMSA — 49 CFR §180.205, General requirements for requalification of specification cylinders. View source

The cycle runs 5, 10, or 12 years depending on cylinder type. The supplier handles re-qualification — one of the reasons cylinder exchange is more economical than owning the cylinders outright.

Construction temporary heat

Job-site temporary heat is propane's other dominant commercial use, particularly in cold-weather climates. The standard delivery is a 250 gal skid tank — a self-contained, portable above-ground tank with feet — placed near the heater inside the building shell or just outside it. A construction-grade direct-fired heater pulls vapor from the tank to dry drywall mud, cure concrete, and keep workers warm.

Skid-tank rental terms vary: some suppliers include the tank in the delivered fuel price, others bill rent per week. NFPA 58 setbacks apply to skid tanks the same as to permanent installations — temporary status does not relax the rule:

“The location of containers and the filling connection of underground containers shall comply with Table 6.4.4.1 with respect to the following: (1) The nearest important building or group of buildings or line of adjoining property that can be built upon.”
NFPA 58, Chapter 6 (Installation of LP-Gas Systems, 2024 ed.). View source

What to ask a commercial propane supplier

Posted residential rate vs. tiered commercial rate — what tier do you
fall into based on projected annual gallons?
Is the per-gallon rate fixed for the term of the agreement, or
posted-rate-minus-discount?
What is the standard delivery SLA (hours from order to fill)?
Who pulls the install permit and handles AHJ inspection?
Cylinder-service rate per fill, plus per-cylinder rental?
Tank ownership: leased, rented, or owner-operator?
After-hours emergency delivery surcharge?
