Before anything about fuel, one paragraph that most buying guides put at the bottom or leave out.
A fire pit is a combustion appliance, and every fuel on this page produces carbon monoxide. That is why every one of them is an outdoor product and why "outdoor" is not a marketing word. Carbon monoxide is colorless and odorless, and the US Consumer Product Safety Commission is direct about the class of behavior that kills people with it: burning fuel inside a house, a garage, a tent or an enclosed porch. Never bring a fire pit of any fuel into a garage, a screened porch you have closed up, a tent, or under any structure that traps the exhaust. If a covered space is where you want to use it, that is a specific question with a specific answer, and it is not the same question as which fuel to buy.
With that said, here is the decision.
The honest first question: do you need one at all?
You are reading a page about fire pits, so this will sound odd coming from us. But a large share of fire-pit regret is not about picking the wrong fuel. It is about buying a thing that gets used four times.
Ask what you actually want. If the answer is heat on a cold evening, a fire pit is a poor heater: it warms what faces it and does almost nothing to the air. If the answer is a place for people to sit around and look at, a fire pit is excellent, and the fuel matters far less than where you can legally and safely put it.
If your yard has no spot that meets the clearances, if your municipality restricts open burning, or if your HOA prohibits it, the honest answer is that no fuel solves that. Check where it can go before you decide what to buy. That order saves more money than any comparison.
The four fuels at a glance
| Fuel | Worst at | Best at | Buy it if |
|---|---|---|---|
| Wood | Smoke, sparks, ash, storing seasoned wood, and it is the fuel most likely to face local restrictions | The fire people actually want: real flame, real heat output, no fuel cost if you have wood | You have space, no burn ban, neighbors not immediately downwind, and you enjoy tending a fire |
| Propane | A uniform, obviously-not-wood flame, a bulky tank to hide and refill, and it will not stay lit in a breeze | Instant on and off, almost no smoke, no ash, often permitted where wood is not | The yard is small, the neighbors are close, or you want a weeknight fire without a project |
| Natural gas | Not portable, ever, and the connection is licensed work with a real installed cost | Never runs out, no tank, lowest running cost of the gas options, permanently installed | You already have gas at the house, you are staying put, and you have priced the installation |
| Gel and ethanol | Very little heat, high fuel cost per hour, a small flame | No smoke, no tank, no gas line, no ash, the smallest footprint | The space is tiny, the goal is atmosphere rather than warmth, and the building's rules allow it |
The four fuels, worst attribute first
Wood
What it is bad at. Smoke, and there is no version of a wood fire that does not produce it. Sparks, which is why wood pits carry the largest clearance requirements and why spark screens exist. Ash, which you have to remove. Storage, because you need somewhere dry to keep seasoned wood. And local rules: open burning is the fuel category most likely to be restricted where you live, and restrictions often tighten seasonally during dry spells.
What it is good at. The fire people actually want. Real flame, real heat output, the sound and smell. No fuel cost if you have wood. No tank to run out mid-evening.
Buy it if you have space, no burn ban, neighbors who are not immediately downwind, and you genuinely enjoy tending a fire. That last one is not a joke: wood is the fuel that requires participation.
Propane
What it is bad at. It looks like a fire and behaves like a gas appliance. The flame is uniform and, to most people, obviously not wood. The tank is a bulky thing you have to hide, refill and store, and storing it is its own set of rules: outdoors, upright, never in a basement or a closed garage, and never indoors. Wind is a real weakness, and a propane pit that will not stay lit in a breeze is a common complaint rather than a defect. Cost per evening is not nothing.
What it is good at. Instant on, instant off, which in practice is the difference between using it on a Tuesday and not. Almost no smoke, which matters on a small lot. No ash. It is the fuel most likely to be permitted where wood burning is not, though that is a question for your own authority rather than an assumption.
Buy it if the yard is small, the neighbors are close, or you want a fire on a weeknight without a project attached.
Natural gas
What it is bad at. It is not portable, at all, ever. And the connection is not homeowner work. Running a natural gas line to a fire pit is licensed work in essentially every jurisdiction, and this article does not describe it. You are hiring a licensed gas fitter or plumber, you are probably pulling a permit, and the installed cost is a real number that has nothing to do with the price on the fire pit's box. Get that quote before you buy the pit, not after.
What it is good at. Never runs out, no tank, lowest running cost of the gas options, and permanently installed so it looks like part of the yard rather than a thing parked in it.
Buy it if you already have natural gas at the house, you are staying put, and you have priced the installation.
Gel and ethanol
What it is bad at. Very little heat, which surprises buyers. Fuel cost per hour is high. Refueling a hot burner is the specific hazard in this category and the manufacturer's instruction on cooling before refueling is not optional. The flame is small.
What it is good at. No smoke at all, no tank, no gas line, no ash, and the smallest footprint. On a balcony or a tiny patio where nothing else is allowed, it may be the only option that is.
Buy it if the space is tiny and the goal is atmosphere rather than warmth. And check your building's rules first, because balconies are frequently where fire restrictions bite hardest.
The specification that actually decides the outcome
Every comparison page argues about BTU. On a fire pit, the number that decides your experience is usually where it can go, and the second is how heavy it is.
Clearance requirements are set by your local authority, not by the seller, and they differ by fuel. A wood pit typically needs substantially more distance from a structure than a gas one. That distance is the real constraint on a small lot, and it is the reason a well-chosen propane pit beats a badly sited wood one every time.
Weight matters because a light pit is a pit that moves, and a moving fire is the thing to avoid. It also determines whether you will ever put it away, which is a bigger factor in how long it survives than the material it is made of.
What the sellers will not tell you
The reason this SERP is confusing is structural. Search for fire-pit safety advice and nearly every result is published by a company that sells fire pits, heat mats, or both. Ask them whether you can put a wood-burning pit on a wooden deck and you will get two confident, opposite answers depending on what the publisher sells. Neither of them is your local fire code.
So treat every clearance number you read online, including any you might expect to find here, as a starting point for a question rather than an answer. The authorities that decide are, in order: your state or provincial rules, your county, your municipality or fire district, and then your HOA, which can be stricter than all of them. The fire pit's own manual sits alongside those and is the one document written specifically about your appliance.
We do not publish a clearance figure for your yard, because we do not know your jurisdiction and a number invented for a national audience is worse than no number.
Before you buy: a five-minute check
- Call or search your municipality or fire district for open-burning rules, and ask specifically whether the answer differs between wood and gas.
- Check your HOA or lease, which is the restriction people find out about last.
- Measure the spot, from the seating to the house, the fence, the eaves, the deck edge and anything overhanging.
- Look up and then look up again. Branches, an eave, a pergola, a soffit. Overhead clearance is the one people forget.
- If it is natural gas, get the installation quote first.
If steps 1 to 4 leave you with nowhere to put a wood pit, you have learned the answer to the fuel question without comparing a single product.
Where this page stops
This page covers the buying decision. It does not tell you how far your pit must be from your house, because that is a local rule. It does not describe connecting a gas line, because that is licensed work. It does not tell you that any fire pit is safe on a deck, because that depends on the pit, the deck and the rule where you live.
If you are unsure whether a specific pit is safe in a specific place, the two documents that answer are the manufacturer's manual and your local fire authority. Neither of them is selling you anything.
Frequently asked questions
Can I use a propane or gel fire pit in a garage or on a screened porch? No. Every fuel on this page produces carbon monoxide, which is colorless and odorless, and the US Consumer Product Safety Commission is direct that burning fuel inside a house, a garage, a tent or an enclosed porch is the class of behavior that kills people. Every fire pit here is an outdoor product.
Which fire pit fuel gives the most heat? Wood delivers real heat output, and gel and ethanol deliver very little, which surprises buyers. But any fire pit is a poor heater: it warms what faces it and does almost nothing to the air, so if heat is the actual goal, a fire pit may not be the right purchase at all.
How far does a fire pit need to be from the house? There is no single number to print for a national audience. Clearances are set by your state, your county, your municipality or fire district, and your HOA, which can be stricter than all of them, alongside the manufacturer's manual. A wood pit typically needs substantially more distance from a structure than a gas one.
Can I run a natural gas line to a fire pit myself? No. It is licensed work in essentially every jurisdiction: you are hiring a licensed gas fitter or plumber, probably pulling a permit, and the installed cost has nothing to do with the price on the box. Get that quote before you buy the pit.
Why will my propane fire pit not stay lit outside? Wind is a real weakness of propane pits, and one that will not stay lit in a breeze is a common complaint rather than a defect. It is worth weighing before you buy if your yard is exposed.
Yard Insight has not run a wood, propane, natural gas or gel fire pit on its own property, and this article makes no claim otherwise. Everything above is drawn from published manufacturer guidance, regulator material and the structure of the market, and where a number depends on your jurisdiction we say so rather than printing one.
