Outdoor fireplace: gas vs wood
This is the decision this page exists to settle, and it is not close once you know which thing you care about.
Gas wins on permission and on effort.Where wood fires are banned, a certified propane appliance is frequently allowed, and that is a binary advantage no amount of wood-fire charm overcomes. It also lights with a knob, produces no ash, no smoke and no ember risk, needs no woodpile, and goes out instantly — which means you can have a fire for forty minutes on a Tuesday, which with wood you realistically cannot.
Wood wins on heat and on character. A gas flame radiates less usable warmth than its BTU figure implies, because a great deal of the energy goes straight up. A 50,000 BTU gas fireplace does not feel like 50,000 BTU of wood fire at your shins. Wood also crackles, smells like a fire and throws light that moves. If what you want is the thing a fire actually is, our wood-burning outdoor fireplace picks are the page you want, and they cost less for more heat.
Running cost favors wood if you have access to firewood and favors gas if you are buying bundles at a gas station. A 20 lb tank running a 50,000 BTU burner does not last long at full output, which is exactly why an adjustable burner is worth having.
Outdoor gas fireplace or gas fire pit?
Same fuel, different shape, and the shape decides what the thing is for.
- A fireplace is vertical. The flame sits at seated eye height behind a firebox opening, it radiates in one direction, and it works as a focal point against a wall or a fence. It warms the people in front of it.
- A fire pit or fire table is horizontal. You sit all the way around it, the flame is below eye level, and it is a social center rather than a feature. See our gas fire pit picks.
If your patio has a wall and the seating runs along it, buy a fireplace. If the seating is a circle, buy a pit or a table — a fireplace at the center of a circle means half your guests are looking at its back. This is the same logic that decides between a chiminea and a bowl, which our outdoor fireplaces hub goes through in full.
What to check on an outdoor gas fireplace listing
- CSA certification, stated on the listing. The permission question, and the one with a real consequence.
- Whether the output is adjustable. A single-setting burner runs flat out or not at all.
- Where the tank goes. Built-in storage keeps the hose short and protected and the patio tidy; a tank strapped to the outside is both ugly and more exposed.
- Overall dimensions. Width is presence, not heat. Check the figure against the wall you are putting it against, because these are furniture-sized objects.
- What the listing does not publish.Several in this category are silent on material, weight and exact dimensions. Our spec tables say “Not published” where that is the case rather than filling in a plausible number.
Safety, even without wood smoke
A gas fireplace removes the ember risk that makes wood fires a problem on decks and under cover, and it does not remove the combustion. These are outdoor appliances.Running one in an enclosed porch, a garage or any space without free air exchange produces carbon monoxide in a place where it accumulates — and the CPSC reports more than 200 accidental non-fire carbon monoxide deaths a year in the US from consumer products. Under a covered patio, the rule is free airflow on at least two sides, and clearance from the roof.
Beyond that: keep the clearances the manual gives from the fence or wall behind it, check the hose and regulator each season, and turn the tank off at the valve rather than only at the control knob. If you want heat on a covered porch specifically and not a fire at all, an electric infrared heater has no combustion products whatsoever and is the honest answer there.
Buying one for a covered space? Gas is the fuel that makes that workable, but the clearance figure still governs and the sides of the space have to be genuinely open. outdoor fireplaces for covered patios walks through the checks before you spend anything.
