# Can you use an outdoor pizza oven indoors? Source: https://peelandflame.co.uk/blog/can-you-use-a-pizza-oven-indoors Published: 2026-10-12 Publisher: Peel and Flame **In short:** No. Gas, wood, charcoal and pellet pizza ovens are designed for outdoor use only and must never be used indoors, in a garage, shed, conservatory, tent, caravan or under an awning. Burning fuel produces carbon monoxide, a poisonous gas you cannot see or smell, and the ovens get hot enough to set nearby materials alight. If you want pizza in the kitchen, choose an electric pizza oven made for indoor use. When the rain sets in, it is tempting to carry a portable pizza oven into the garage or kitchen. Please do not. Fuel-burning pizza ovens produce carbon monoxide and run at temperatures of several hundred degrees, and they are built to vent fumes and heat into open air. This guide explains why gas and wood-fired ovens are outdoor only, which spaces still count as indoors, and the electric countertop ovens that are made to be used safely in a kitchen. ## Why fuel-burning ovens are outdoor only Any appliance that burns gas, wood, charcoal or pellets uses oxygen and gives off combustion gases. One of these is carbon monoxide (CO). In open air it disperses harmlessly. In an enclosed or partly enclosed space it builds up, and breathing it in stops your blood carrying oxygen properly. Early symptoms such as headache, dizziness, nausea and tiredness are easy to mistake for a cold or food poisoning. High levels can cause collapse and death. Portable pizza ovens have no flue to take fumes outside. Wood and pellet ovens also produce smoke and sparks from the chimney. On top of that, the oven body, chimney and opening get extremely hot, and they are designed to stand clear of walls, ceilings and anything that can burn. Every maker of gas and wood-fired pizza ovens says they are for outdoor use only. Note: Never use a gas, wood, charcoal or pellet pizza oven indoors, including in a garage, shed, conservatory, tent, caravan, gazebo with sides or under an awning. Carbon monoxide can kill. Fit a carbon monoxide alarm in your home, and if anyone feels unwell near a fuel-burning appliance, get them into fresh air and seek medical help. ## Spaces that still count as indoors Outdoor means in the open air, with fumes free to disperse. Some spaces feel outdoors but are not safe for a pizza oven. A garage with the door open still traps fumes near the ceiling and towards the back. A conservatory or garden room is an enclosed room. A gazebo with side panels, a covered pergola with walls on several sides, or a deep porch can all hold smoke and gas. Tents, awnings and caravans are especially dangerous because fumes reach the people inside quickly. Even outdoors, place the oven well away from open doors and windows, air vents and air bricks so fumes do not drift into the house. Keep it clear of fences, sheds, overhanging branches and anything that can catch fire. - Not safe: kitchen, garage, shed, conservatory, summer house, tent, caravan, awning. - Not safe: a gazebo or pergola with sides, or a tight corner against the house. - Safe: an open patio or lawn in free air, on a stable heat-proof surface, away from doors, windows and vents. ## What about rain and a covered patio? Many people want to cook under cover when it is wet. A fully open-sided roof well above the oven may be acceptable for some appliances, but the oven's manual has the final word, and many specify clearance above the oven as well as around it. If in doubt, cook in the open and simply wait for a dry spell. A wet stone takes longer to heat, and the guide to [how long pizza ovens take to heat up](https://peelandflame.co.uk/blog/pizza-oven-heat-up-times) explains why weather matters. If you want to cook through the winter regardless of the weather, an electric oven indoors is the safer and more practical answer. ## Electric pizza ovens made for the kitchen Electric countertop pizza ovens are designed for indoor use. They use heating elements above and below a stone, plug into a standard socket and produce no combustion fumes. Several reach around 400°C or more according to their makers, which is far hotter than a domestic oven and enough for a thin, blistered crust in a few minutes or less. Examples in our data include the Sage Smart Oven Pizzaiolo, the Kenwood My Pizzeria, the Chefman 30 cm indoor oven, the Daewoo 12 inch electric oven and the BIG HORN OUTDOORS 14 inch electric oven. Compare them in our [best electric pizza oven for indoors](https://peelandflame.co.uk/best/best-electric-pizza-oven-for-indoors) guide. Give them clear space on a heat-resistant worktop, as the outside gets hot, and follow the maker's guidance on clearances.

The Ninja Woodfire outdoor oven, for example, is electric but burns a small amount of wood pellets for smoky flavour, so it belongs outside. The Ninja Artisan is sold as an electric outdoor pizza oven. Being electric does not make an oven safe for indoors: check the listing and manual for the words indoor use. Equally, a few countertop ovens say they can be used indoors or outdoors. That is fine, as long as you keep them dry and use a suitable outdoor socket.

Permanent indoor wood ovens exist, but they need a proper flue built and signed off by professionals. **Is there an indoor Ooni pizza oven?** Ooni sells an electric model aimed at indoor use, while its gas and wood ovens are outdoor only.
