Wood-fired and multi-fuel
Solo Stove Pi: the multi-fuel oven that arrived complete
Wood assembly and gas burner, both in the box, in a 30.5 pound stainless drum. Nothing else here does that — and the published 850 degree ceiling is the price.
The short answer
The Pi was the oven for trying both fuels without a second purchase. The wood-burning assembly and the gas burner both shipped in the box, the body is 304 stainless at 30.5 lb, and propane preheat was published at about 15 minutes. The real cost was the ceiling: 850 F, which is 100 F below almost every rival and puts a true 60-second Neapolitan out of reach.
Every other multi-fuel oven on this site makes you choose a starting fuel and buy the other one later. Ooni's Karu line ships wood-ready with the gas burner separate; Gozney's Roccbox ships gas-ready with the wood burner separate. Both are honest about it, and both mean the advertised price is not the multi-fuel price.
The Solo Stove Pi and the Bertello bundles were the exceptions — and neither is sold on Amazon any more.
What arriving complete is actually worth
More than it sounds, for a specific reason: it removes the decision. Owners who have to buy a second burner mostly never do, and end up permanently on whichever fuel their oven shipped with — which quietly turns a multi-fuel purchase into a single-fuel one.
With both systems in hand from day one you can actually run the experiment the fuel guide describes: gas on a weeknight, wood on a Saturday, and an honest answer within a month about which one you reach for. That is a genuinely different ownership experience from reading about it.
304 stainless, and why it matters outdoors
The Pi's body is 304 stainless steel throughout, where most ovens in this bracket use powder-coated carbon steel.
For an appliance that lives outside, gets rained on when somebody forgets, and sits under a cover through a winter, that is a materially better material. Powder coat chips, and what is under it rusts outward from the chip. Stainless does not have an underneath. It is the same argument that runs through the Pi Prime review, and it is the most durable-feeling thing about both ovens.
The 850 degree ceiling is the real trade
Solo Stove publishes 850 F. Almost everything else in this category publishes 950 F — the Bertello Grande is 900 F, and the Pi is the lowest outdoor figure on the site.
One hundred degrees sounds marginal and is not, because of where in the range it sits. Neapolitan is defined partly by a 60-to-90-second bake, and that needs a floor around 800 to 900 F. At an 850 F ceiling you are working at the very bottom of that window with no headroom, and in practice you are cooking a slightly longer bake — which is a good pizza and not that one. How hot a pizza oven should be sets out the target ranges by style.
Worth noting that it is exactly the same ceiling as the indoor Ooni Volt 2 — an electric countertop oven limited by a wall socket. The Pi is an outdoor wood-and-gas oven with no such constraint, and it lands in the same place.
The rest of the specification
15.125 in high by 20.5 in diameter, 30.5 lb. A round drum rather than a box, and round bodies carry more comfortably than rectangular ones of the same mass — though there are no retractable legs or carry strap, so this is light rather than purpose-built for travel.
A 13 mm (about 0.51 in) cordierite stone. Solo Stove publishes the thickness, which several makers at this price do not. It is on the thin side, and wood firing is where floor heat does the most work, so expect a recovery pause between bakes.
About 15 minutes to preheat on propane, which is quick — quicker than the Roccbox's published 20 to 30 minutes. See how long to preheat for why the published figure is the chamber and not the stone.
Where it falls down
12 in, permanently. The round chamber caps it, and there is no larger Pi.
850 F. Stated again because it is the specification most likely to disappoint someone who bought on the multi-fuel headline without reading the ceiling.
0.51 in of stone under a wood fire. The thinnest floor of any wood-capable oven here, in the application where floor heat matters most.

Max pizza and weight are the makers’ published figures, sourced on each write-up below. Neither is a measurement we took, and no column here is a score — we have not cooked on these ovens and will not pretend otherwise.
Top pick · Both fuels and a peel in one order
Ooni Karu 2 Multi-Fuel Pizza Oven, Ultimate Bundle with 12 in Perforated Peel and Gas Burner
Ooni · Multi-fuel
The Karu 2 sold with the two things it otherwise lacks: its gas burner and a 12 in perforated peel. Same oven, same glass door and 0.6 in stone — the bundle removes the second-burner trap and the first accessory purchase.
Published specification
- Max temperature
- 950 F, reached in about 15 minutes per the listing
- Stone
- 13.3 in cordierite, 0.6 in (15 mm)
- Max pizza
- 12 in
- Weight
- 33.6 lb, oven unboxed
- In the bundle
- Karu 2 oven, Karu 2 gas burner, 12 in perforated peel
- Fuel
- Wood or charcoal, or propane through the included burner
- Door
- Borosilicate glass with ClearView, built-in thermometer
- Warranty
- 1 year, extended to 5 years on registration with Ooni
What it does well
- Both fuel systems arrive together, so you are not left permanently on whichever fuel the oven shipped with
- A correctly sized 12 in perforated peel in the box — the accessory every oven needs first
- The same glass door and built-in thermometer as the standalone Karu 2, which is the feature that makes wood firing manageable
What you give up
- Still a 12 in chamber: turning room around a 12 in pizza is tight, and the one-side burn problem is real
- You pay for the gas burner up front whether or not you end up using gas
- No cover and no infrared thermometer in this bundle — the built-in gauge reads the chamber, not the stone
Buy it if
Someone who wants to cook on wood and on gas from the first evening without placing a second order.
Skip it if
Anyone certain they will only ever burn wood — the standalone Karu 2 is the same oven without the burner.
Pick 2 · The one maker that publishes its burner rating
Solo Stove Pi Prime Propane Pizza Oven
Solo Stove · Propane
A demi-dome over a cordierite stone, 304 stainless throughout, and — almost uniquely here — a published 15,000 BTU burner and a published 20-hour runtime on a 20 lb cylinder.
Published specification
- Max temperature
- 950 F; about 15 minutes to preheat
- Bake time
- Listing states 90 seconds, not 60
- Opening
- 13 in wide
- Body
- 20.5 in wide x 15.5 in tall, 304 stainless steel
- Weight
- About 30 lb
- Burner
- 15,000 BTU
- Fuel runtime
- Up to 20 hours on high from a 20 lb LPG cylinder
What it does well
- Solo Stove publishes both a BTU figure and a tank runtime. Almost nobody else in this category does, and it is the reason our propane runtime guide can use real arithmetic
- The demi-dome pushes heat back down onto the pizza rather than out the front — a genuinely different shape from the flat-top Kodas
- 304 stainless rather than powder-coated carbon steel: the better material for something that lives outdoors
- About 30 lb, so it stays in the carry-it-yourself class
What you give up
- The listing's own claim is a 90-second bake, not 60. That is an honest number and it is also a slower oven
- 13 in opening means 12 in pizzas, and the stone thickness is not published
- Propane only, and the wide mouth that makes turning easy also loses heat faster on a cold evening
Buy it if
The buyer who wants to compare burners on paper before buying, and who values a stainless body outdoors.
Skip it if
Anyone who has decided 16 in is the minimum.
Where these numbers came from
Solo Stove's current answer for wood is not a standalone oven at all. The Pi Fire is a chamber that sits on top of one of its fire pits, and its listing publishes a 650 F stone ceiling — about 300 F below what the Pi itself published.
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.
