FL Gas Appliance Load Calculator
Select all gas appliances you're adding or already have. This determines your total BTU load — the foundation for gas meter sizing, pipe sizing, and utility service requirements in Florida. Typical appliance loads:
| Appliance | Approx. BTU |
|---|---|
| Whole-house generator — 10kW | ~100K BTU |
| Whole-house generator — 20kW | ~200K BTU |
| Whole-house generator — 30kW | ~350K BTU |
| Gas range / cooktop (standard) | ~40K BTU |
| Gas range — professional (6-burner) | ~65K BTU |
| Tankless water heater — small (3–5 GPM) | ~35K BTU |
| Tankless water heater — whole-home (10+ GPM) | ~199K BTU |
| Tank gas water heater (40–50 gal) | ~40K BTU |
| Gas pool / spa heater | ~75K BTU |
| Gas pool heater — large | ~400K BTU |
| Gas furnace / air handler | ~100K BTU |
| Gas dryer | ~30K BTU |
| Outdoor gas grill (permanent hookup) | ~60K BTU |
| Gas fireplace insert | ~50K BTU |
| Gas log set (decorative, no firebox) | ~25K BTU |
FL Generator Demand — Post-Hurricane Facts
Why FL Plumbers Love Generator Connections
After every major FL hurricane, generator inquiries spike 400–600%. A permanent natural gas or propane generator never runs out of fuel. FL building code requires a licensed plumber (CFC) to install gas piping to the generator pad. This is one of the highest-margin service calls in FL plumbing — typical job: $800–$3,500 installed.
- FL generators sold 2020–2024: 2.1 million units
- Permanent standby preferred: natural gas or propane
- FL license required: CFC (plumber) + electrical
- Permit required? Yes — gas + electrical both
- Average gas line run to pad: 30–80 feet in FL yards
- Most popular generator brand in FL: Generac (55%), Kohler (22%)
FL Gas Pipe Sizing Guide
Florida uses IFGC (International Fuel Gas Code) pipe sizing tables. Enter your load and run length to get the recommended pipe diameter for natural gas (Schedule 40 black iron) or CSST (corrugated stainless steel tubing).
FL Gas Pipe Material Comparison
Black Iron (Schedule 40 Steel)
Most common FL residential interior gas pipe. Threaded black steel pipe has been the FL standard for interior gas distribution for decades. Requires coating or wrapping in coastal FL (salt air corrosion). Must be bonded and pressure-tested per IFGC. Cannot be used underground without approved wrapping. Code-compliant everywhere in FL. Code-universal; heavy, slow install; lowest material cost.
CSST (TracPipe / FlexPro / OmegaFlex)
Fastest installation — 30% less labor than black iron. Corrugated stainless steel tubing is now the preferred FL gas piping method for new construction. Flexible routing eliminates many fittings. CSST requires arc-flash bonding per NFPA 54 — this is mandatory in FL. Every CSST fitting joint must be accessible. Must be bonded at every appliance connection. Popular for generator runs through tight FL crawl spaces. Fast install; bonding required; higher material cost.
PE Pipe (Underground Service)
For underground runs from utility meter or propane tank. Yellow PE pipe is the standard for underground gas distribution in FL. Used from the street tap to the meter, and from propane tanks to the structure. Cannot be used above ground inside structures. Must transition to black iron or CSST at the building entry. FL requires minimum 12-inch burial depth for PE gas pipe. Underground only; utility standard; must transition at structure.
FL Gas Pressure Zones
- Utility service pressure (NG): 0.25–2 PSI typical
- Low pressure system (standard): under 0.5 PSI (14" WC)
- Medium pressure system: 0.5–2 PSI — larger homes
- FL code pressure test: 1.5× working pressure, 10 min
- FL code leak test: soap bubble or electronic detector
- Propane tank distance (code): 10 ft from building (<500 gal)
- Propane tank distance (500+ gal): 10–25 ft depending on size

FL Generator Season Tip
June 1 – November 30 is FL hurricane season. Don't wait until a storm is forecast — permit wait times jump from 3 days to 3 weeks during storm prep surges. Schedule your generator gas line installation in April or May for guaranteed pre-season readiness. A 22kW Generac with proper gas sizing will run your entire FL home indefinitely on utility gas.
