Indoor vs. Outdoor: Where Will You Use It?

This is the first question to answer, because it determines which fuel types and product styles are available to you.

Indoor fire features must be ventless or designed for enclosed spaces. Gel fuel and bio-ethanol are the two real-flame options that work indoors without a chimney or gas line. These include tabletop fire pits, wall-mounted fireplaces, and freestanding ventless units.

Outdoor fire features have more flexibility. You can use gel fuel, bio-ethanol, propane, natural gas, or wood-burning fire pits. Your choice depends on how much heat you want, how much maintenance you are willing to do, and whether you have a covered or open space.

Fuel Types Compared

Each fuel type has distinct advantages. Here is an honest comparison:

Gel Fuel

  • Best for: tabletop units, covered patios, indoor fireplaces
  • Heat: low (~3,000 BTU per canister)
  • Burn time: 2-3 hours per 13 oz canister
  • Pros: no smoke, no soot, no installation, indoor safe, cap and reuse
  • Cons: lower heat output, recurring canister cost

Bio-Ethanol

  • Best for: wall-mounted fireplaces, larger freestanding units
  • Heat: moderate (~6,000-8,000 BTU)
  • Burn time: 4-5 hours depending on reservoir size
  • Pros: clean burn, no smoke, higher heat than gel, indoor safe
  • Cons: liquid fuel requires careful pouring, higher initial cost

Propane

  • Best for: large outdoor fire pits, fire tables
  • Heat: high (~40,000-60,000 BTU)
  • Burn time: 8-10 hours per 20 lb tank
  • Pros: high heat, adjustable flame, long burn time
  • Cons: outdoor only, tank storage, no indoor use

Wood-Burning

  • Best for: open outdoor spaces, traditional campfire experience
  • Heat: varies widely
  • Pros: traditional experience, crackling sounds, high heat
  • Cons: smoke, ash cleanup, sparks, not for covered spaces, not indoor safe

Size Considerations

Match your fire product to your space:

  • Tabletop units (6-12 inches): Perfect for dining tables, coffee tables, small patios. Gel fuel or bio-ethanol.
  • Medium freestanding (18-30 inches): Good for patios, screened porches, living rooms. Multiple fuel options.
  • Large fire tables (30-48 inches): Outdoor entertaining centerpiece. Usually propane or natural gas.

For indoor use, smaller is generally better. A tabletop gel fuel fire pit on a dining table creates more ambiance than a large unit that overwhelms the room.

Safety Essentials

Regardless of which fire product you choose, these rules apply:

  • Never leave unattended. Any open flame should be supervised.
  • Keep away from flammable materials. Maintain clearance from curtains, paper, and other combustibles.
  • Use on stable, level surfaces. A fire pit that tips over is dangerous.
  • Follow manufacturer instructions. Every product has specific placement and fuel requirements.
  • Keep a fire extinguisher accessible. Especially for indoor use.
  • Never add fuel to a burning flame. Wait until the fire is completely out and the unit has cooled.
  • Keep away from children and pets. The flame is real and the unit will be hot during and after use.

Maintenance

Fire products that use gel fuel or bio-ethanol require minimal maintenance:

  • Wipe the unit with a soft cloth after use
  • Remove empty gel fuel canisters and dispose of them properly
  • Check the burner or canister holder for debris before each use
  • Store outdoor units in a dry location or use a weather cover when not in use
  • Inspect for cracks, chips, or damage periodically

Propane and wood-burning units require additional maintenance including tank inspections, ash removal, and seasonal deep cleaning.

Frequently Asked Questions

A small tabletop gel fuel fire pit is usually the best option. It produces no smoke, requires no hookups, and is approved for use in enclosed outdoor spaces. Check your building rules first, as some apartments prohibit open flames on balconies.

Gel fuel and bio-ethanol tabletop units are generally safe on wooden decks since they produce no sparks and minimal heat at the base. For larger units, use a fire-resistant mat underneath. Never use a wood-burning fire pit directly on a wooden deck.

Quality tabletop gel fuel fire pits start around $40-80. Wall-mounted bio-ethanol fireplaces range from $150-500. Large propane fire tables can run $300-1,500. Buy for the quality and features you need. A $60 gel fuel tabletop unit that you use weekly is a better purchase than a $500 unit that sits unused.

Gel fuel and bio-ethanol fire features typically do not require permits. Propane and natural gas installations may require permits depending on your local codes. Wood-burning fire pits may be restricted or banned in some areas. Check your local fire department or municipal codes.
