Quick Answer: Gas pizza ovens reach higher peak heat (~900-950°F claimed by Ooni and Gozney) and cost less at the entry level (Gozney Roccbox $399.99, clearance Ooni Koda 12 $299), but they’re outdoor-only — an open propane flame isn’t safe indoors. Electric ovens top out lower (Ooni Volt 2 at 850°F, per Ooni’s own spec) and — contrary to what most buyers assume — don’t preheat any faster, but they run on a standard 120V outlet and are the only option for apartments, condos, or any kitchen without outdoor space. The decision isn’t really about heat or cost; it’s about where you’re allowed to put the oven.
Most people frame this as a performance question — which oven bakes a better pizza — but after comparing the two fuel types on temperature, preheat time, and where each is legal to use, the real decision axis is location. According to Ooni’s own spec sheets, the gas-fired Koda 16 and Koda 12 are rated to roughly 950°F, while the hottest electric model, the Ooni Volt 2, tops out at 850°F — a real but modest gap, and one that’s closed further once you account for real-world preheat and bake times. The bigger practical difference is that gas ovens burn an open propane flame and are built exclusively for outdoor use, while electric ovens plug into a normal household outlet and can run on any countertop, indoors or out.
Electric vs gas by the numbers
- 850°F vs ~950°F: the peak temperature Ooni rates its hottest electric oven (Volt 2) against its hottest gas ovens (Koda 12/16) — gas still wins on paper, per Ooni’s own product specs.
- 20-25 minutes vs 15-20 minutes: the real preheat gap runs backwards from what most buyers expect. Engadget and Tom’s Guide both measured the Volt 2 at 20-25 minutes to full temperature, slower than the 15-20 minutes Ooni and Gozney quote for their gas ovens.
- 905°F: the deck temperature the AVPN (Associazione Verace Pizza Napoletana) specifies for a true 60-90 second Neapolitan bake — gas ovens clear this comfortably; the Volt 2 sits just under it.
- 25-40 bakes per 20 lb tank: roughly how many pizzas a gas oven gets from a single full propane tank, keeping gas fuel cost in the same ballpark (pennies per pizza) as an electric oven’s well-under-1-kWh draw per bake.

Where you can actually put the oven decides more than heat does
This is the part most comparisons skip. A gas pizza oven runs an open propane flame that needs to vent freely — every manufacturer, from Ooni to Gozney to Solo Stove, specifies outdoor use only, on a stable non-combustible surface with clearance from walls and structures. There’s no certified indoor gas pizza oven on the consumer market. If your only cooking space is an apartment kitchen, a condo balcony with fire restrictions, or anywhere an HOA or lease bans open flame, gas isn’t a legal option regardless of how good the Roccbox or Koda 16 looks on paper.
Electric ovens sidestep that entirely. The Ooni Volt 2, Breville Pizzaiolo, and Cuisinart CPZ-120 all run on a standard 120V household outlet — the same circuit a microwave or space heater uses — and none of them produce combustion byproducts, so they’re fine on an indoor countertop. That’s the actual reason to buy electric: not speed, not lower running cost, but the ability to make a 900°F-class pizza somewhere a gas flame simply isn’t allowed.
Ooni Volt 2 — the electric oven that gets closest to gas heat
- 850°F per Ooni's spec — the smallest gap to gas of any plug-in oven on the market.
- Runs on a standard 120V outlet on any indoor countertop — no ventilation retrofit needed.
- One-touch pizza presets and a dough-proofing mode take the guesswork out of a first bake.
Once the oven’s picked out, groceries are the other half of pizza night — Amazon Fresh can get fresh mozzarella, basil, and 00 flour to your door before the stone even finishes preheating.
The preheat gap runs backwards from what people expect
It’s tempting to assume a plug-in appliance heats up faster than something you have to light and wait on, but the measured numbers say otherwise. Engadget’s and Tom’s Guide’s independent testing both clocked the Ooni Volt 2 at 20-25 minutes to reach its full 850°F — slower than the 15-20 minutes Ooni and Gozney quote for their gas ovens reaching a comparable or higher temperature. The reason is physics, not marketing: an electric heating element has to warm the oven’s mass gradually, while a propane flame delivers concentrated heat directly to the stone from the first minute. If speed to your first pizza matters more than anything else, gas still wins — electric’s real edge is location, not a faster route to dinner.
Gozney Roccbox — the gas pick that undercuts most electrics on price
- ~950°F claimed ceiling with a built-in thermometer, per Gozney's spec sheet.
- 15-20 minute preheat — faster to a finished pizza than any electric oven here.
- Outdoor use only, on propane or an optional wood burner.
Fuel cost isn’t the deciding factor either way
A 20 lb propane tank fuels roughly 25-40 pizza sessions on a gas oven, working out to pennies per bake. An electric oven pulling 1,500-1,800 watts through a 20-25 minute preheat plus a 2-minute bake uses well under 1 kWh total — also a few cents at typical US residential electricity rates. Neither fuel type has a meaningful cost advantage over the other; don’t let running cost drive this decision.
Who should buy which
Buy gas if you have a yard, patio, or balcony where an open flame is allowed. You’ll get a higher claimed ceiling, a faster route to your first pizza, and — with picks like the Ooni Koda 12 at $299 or the Gozney Roccbox at $399.99 — a lower entry price than most electrics.
Buy electric if your only cooking space is indoors, or your lease/HOA bans open-flame cooking outside. The Ooni Volt 2 gets you within 100°F of gas-oven heat on a standard household outlet, and the Breville Pizzaiolo automates the hardest part (balancing top and bottom heat) for total beginners.

The bottom line
Gas wins on peak temperature and price at the entry level; electric wins on being usable somewhere a propane flame legally can’t go. If you have outdoor space, the Gozney Roccbox ($399.99) or a clearance Ooni Koda 12 ($299) beats any electric oven on heat and price. If you don’t, the Ooni Volt 2 ($699, often ~$499 on sale) is the closest a plug-in oven gets to real gas-oven performance — just don’t expect it to preheat any faster.
