Indoor and electric ovens
Indoor or outdoor: which pizza oven will you actually use?
The specification comparison favors outdoor gas. The usage comparison often does not, and usage is what determines whether the purchase was worth it.
The short answer
Outdoor gas wins on temperature and size: 950 F and up to 20 in of pizza, against 850 F and 12 in for the best indoor oven. Indoor wins on frequency — no cylinder, no weather, no setup, and it gets used in February. If your honest answer to "how often?" is weekly year-round, buy indoors. If it is "weekends in summer", buy outdoors.
What the placement rating actually protects
These ratings are not marketing segmentation, and they are not interchangeable. An outdoor gas oven is an open-flame combustion appliance: it consumes oxygen and produces combustion products, which is why it needs genuine outdoor ventilation and open sky above it. Bringing one indoors, into a garage, or under a low enclosed roof is a carbon monoxide question, not a convenience question.
An indoor electric oven is rated for a kitchen because it has no combustion at all and because it manages its own exhaust — the Ooni Volt 2's filtration system is what makes it a kitchen appliance rather than a patio one. Ooni nonetheless specifies it as indoor only, because outdoor rating involves moisture ingress and temperature range that the design does not cover.
Read the rating for the specific model. The older Ooni Volt 12 was rated for both; the Volt 2 is not. The Ninja Woodfire is outdoor only. These differ within one brand and one product line.
The specification gap, honestly stated
| Best indoor electric | Best outdoor gas | |
|---|---|---|
| Peak temperature | 850 F | 950 F |
| Max pizza | 12" | 20" |
| Bake time | 90 s to 2 min | 60 s |
| Thickest stone available | 0.4" | 0.8" |
| Runs in February | Yes | Weather permitting |
| Setup per session | Plug in | Cylinder, position, weather check |
The two categories at their best, on published figures. The size limit on electric ovens is not a market gap — it is the wall socket, and it is not going to change.
But the specification is not the decision
Making good pizza at home is a skill, and skills need repetitions. Launching, turning, reading the stone, adjusting dough — none of it improves by owning a better oven, and all of it improves by cooking more often.
That reframes the whole question. An 850 F oven used forty times a year produces far better pizza than a 950 F oven used eight times, because the person operating it has forty sessions of practice rather than eight. The friction that decides the difference is not the oven's ceiling — it is the cylinder, the weather, the setup and the fifteen minutes of getting everything outside.
Who should buy which
Buy indoors if you live in an apartment, have a real winter, have no suitable outdoor surface, or want pizza to be a weeknight option. Also buy indoors if the alternative is an outdoor oven that will live in a garage nine months of the year, which is a very common outcome.
Buy outdoors if you want 16 in pizzas, a true 60-second Neapolitan bake, wood fire, or to cook for more than four people at once. All four of those are genuinely unavailable indoors and no amount of frequency argument changes that.
Buy the Ninja Woodfire if your patio is covered, you have a suitable 20 A circuit, and you want to sidestep both cylinders and fire management. It is the awkward middle option and for a specific setup it is the right one.

Top pick · 850 F on a normal kitchen outlet
Ooni Volt 2 Electric Indoor Pizza Oven
Ooni · Electric
1600 W on a standard 120 V outlet, and 850 F on a stone floor. It is the only oven here that turns a kitchen counter into something close to a pizzeria deck.
Published specification
- Power
- 120 V / 1600 W, standard North America Type B plug
- Temperature
- 70 F to 850 F (450 C)
- Stone
- Cordierite, 0.4 in (10 mm)
- External size
- 21.5" x 17.4" x 10.4"
- Opening height
- 3.6 in
- Weight
- 38.8 lb
- Body
- Powder-coated carbon steel, triple-paned tempered glass door
- Placement
- Indoor use only
What it does well
- 1600 W draws about 13.3 A, which fits inside a standard 15 A North American kitchen circuit — that is the whole reason this oven is practical. See power requirements
- A proof mode that goes down to 70 F means the same appliance proofs the dough it later bakes
- Triple-paned glass and a filtered exhaust are why this can live in a kitchen and a Koda cannot
- 850 F is roughly 300 F hotter than a domestic oven's maximum, which is the entire difference in crust
What you give up
- 0.4 in stone is the thinnest floor in this registry. Consecutive bakes need recovery time and the oven's control system spends its effort managing exactly that
- 850 F, not 950 F: a true 60-second Neapolitan is out of reach and Ooni does not claim it
- 3.6 in of opening height rules out deep pan builds
- Indoor use only, stated by Ooni — this is not an outdoor oven that also works inside
Buy it if
Apartments, winter, and anyone whose real obstacle is that the oven has to live indoors.
Skip it if
Anyone whose target is a 60-second, 950 F Neapolitan.

Pick 2 · The default first oven
Ooni Koda 16 Propane Gas Pizza Oven
Ooni · Propane
Still the most sensible first gas oven anyone buys. 16 inches is the size where a 12-inch pizza stops feeling like a tight squeeze, and at 40 lb one person can carry it.
Published specification
- Max temperature
- 950 F (500 C), reached in about 20 minutes
- Stone
- 16 in cordierite, 0.6 in thick
- External size
- 25" L x 23.2" W x 14.7" H
- Weight
- 40.1 lb unboxed
- Fuel
- Propane, or a separate natural-gas version for a gas line
- Warranty
- 1 year standard, 5 years on registration with Ooni
- Gas input
- Ooni does not publish a BTU input rating for the Koda line
What it does well
- The 16 in stone is the real argument for this model over the 12 in ovens — a 12 in pizza sits inside it with room to turn, which is what actually stops a burnt edge
- One-piece body with folding legs: no assembly, and it is the largest oven here a single person carries comfortably
- There is a natural-gas variant, so a household with a gas line can stop buying cylinders entirely — rare in this category
What you give up
- 0.6 in stone stores less heat than the 0.8 in floors on the newer Koda 2 Pro and the Gozney Arc, so back-to-back bakes need a longer recovery pause
- Single burner across the back: no dual-zone control, so everything cooks at one temperature
- No door and no glass, so the heat you lose between launches is heat you re-earn with the flame
Buy it if
Someone buying their first serious outdoor oven who wants 16 in capacity and does not want to think about fuel beyond turning a dial.
Skip it if
Anyone who wants wood flavor, and anyone cooking two different things at once — that is the Koda 2 Pro or the Karu.

Pick 3 · Electric outdoors, with real smoke
Ninja Woodfire 8-in-1 Outdoor Oven (OO101)
Ninja · Electric
2400 W outdoors, 105 F to 700 F, and a pellet box that puts genuine wood smoke into an electric oven. It is the only appliance here that bridges the electric and wood-fired arguments.
Published specification
- Power
- 2400 W
- Temperature range
- 105 F to 700 F
- Smoke
- Half a cup of pellets per cook, in a dedicated box
- Size
- 21.5" W x 18" D x 15.1" H
- Functions
- Eight, including pizza, smoker, roast, bake and dehydrate
- Placement
- Outdoor
What it does well
- Real wood smoke without a fire to manage — the pellet box is the honest middle ground in the wood versus gas argument
- The widest temperature range here by a distance: 105 F to 700 F covers dehydrating through pizza in one appliance
- Electric outdoors means no cylinders, no ash, and no tank runtime arithmetic
What you give up
- 2400 W is 20 A at 120 V, which does NOT fit a standard 15 A circuit alongside anything else. Check the outdoor circuit before buying — see power requirements
- 700 F is the lowest ceiling in this registry; the Neapolitan preset takes about 3 minutes, not 60 seconds
- It is eight appliances in one, which means it is not the best at any of them
Buy it if
A covered patio with a suitable outlet, and a cook who wants smoke flavor without tending a fire.
Skip it if
Indoors, high-temperature Neapolitan, or a 15 A circuit.
How these picks were made
We did not cook on these ovens. Every figure on this page is the maker’s or the listing’s published specification, cited on each write-up so you can check it in one click. The ranking comes from matching those published capabilities to a stated use case — space, pizza size, fuel, and how many pizzas you cook in a row. Where a maker does not publish a number, we say so instead of estimating one.
The full version of that argument, including what we deliberately do not claim, is on our methodology page.
