Fuel Delivery in Washington

We're not in Washington yet — drop your email and we'll tell you the moment local dealers join.

Washington pairs the wet Puget Sound corridor and the Olympic Peninsula with the Cascade volcanoes, the Columbia Basin, and the dry plateau east of the mountains; propane is the off-grid heating fuel for the Cascades and the Okanogan country. Across the Pacific Coast, propane fills the gap for whole-home heat, hot water, cooking, and standby generators across the parts of Washington that sit beyond the natural-gas mains.

How Washington heats its homes

American Community Survey 2022 5-year estimates, rounded for narrative use:

  • Natural gas: ≈33% of housing units
  • Heating oil and kerosene: ≈5% of housing units
  • Propane (LP-Gas): ≈5% of housing units
  • Electricity: ≈53% of housing units
  • Wood, solar, and other / no fuel: ≈4% of housing units

The mix tilts toward natural gas in the populated corridors and propane out in the dispersed rural counties.

Heating climate in Washington

Washington averages about 5,000 heating degree days per year — a long, cool heating season. Heating demand drives the propane delivery cycle from the first hard frost through the last spring cold snap, with usage swinging sharply between mild and severe winters.

Nearby states

Washington shares a land border with Idaho and Oregon. Once dealers join from any of these states we’ll surface them here so you can compare delivery options across the regional market.

Propane installations are governed by NFPA 58, the Liquefied Petroleum Gas Code — the consensus standard for storage, transfer, dispensing, and use of LP-Gas. NFPA 58 is widely adopted by reference into state and local fire codes, and state and local Authorities Having Jurisdiction (the AHJ) — typically the state fire marshal’s office, local fire departments, and building/permitting offices — enforce setback distances, tank-placement clearances, installer-licensing requirements, and any state-specific overlay on top of NFPA 58. Always confirm permitting and inspection requirements with a licensed installer and your local AHJ before any tank install, modification, or fuel switch.

“This code shall apply to the storage, handling, transportation, and use of liquefied petroleum gas (LP-Gas).”
