LP Cylinder Options
The right propane tank depends on your generator size, lot layout, HOA rules, and how long you need to run during an outage. We help you choose the right option.
Above Ground LP Cylinders
Above ground propane tanks are the most common choice for residential standby generator fuel. Easy to access for refills, inspections, and service. Available in a range of sizes to match your generator's runtime requirements.
- 100 lb – 1,000+ gallon options
- Easy access for delivery trucks
- Lower installation cost

Buried / Underground LP Cylinders
Buried propane tanks keep your yard looking clean and uncluttered. They're protected from weather and temperature extremes, which can actually improve fuel consistency. A popular choice for HOA communities and larger properties.

- HOA-friendly installation
- Protected from weather extremes
- Requires proper excavation & permitting
Propane Cylinders (Portable)
Smaller portable propane cylinders are used for portable generators, outdoor appliances, and supplemental fuel needs. We can advise on the right cylinder size for your specific generator model and usage.

Propane Cylinder FAQs
What size LP tank do I need for a Generac generator?
It depends on your generator's kW output and how long you want to run it during an outage. A 22kW Generac typically consumes about 2.1 gallons/hour at full load. A 500-gallon tank gives you roughly 7–10 days of runtime. We size the tank during your no charge consultation.
Do I need a permit for a propane tank installation in Florida?
Yes — propane tank installations in Florida require permits and must be installed by a licensed contractor. Double A handles all permitting as part of the installation process.
How far does a propane tank need to be from my house?
Florida code requires above-ground tanks of 125 gallons or more to be at least 10 feet from any building or ignition source. Buried tanks have different setback requirements. We survey your property and ensure full code compliance.
Can I use an existing propane tank for my new Generac generator?
Possibly — it depends on the tank size, age, condition, and proximity to the generator. We inspect existing tanks as part of every generator installation consultation.
