# Which Ooni pizza oven? The range explained Source: https://peelandflame.co.uk/blog/ooni-pizza-oven-range-explained Published: 2026-10-12 Publisher: Peel and Flame **In short:** Ooni groups its ovens by fuel. Koda ovens run on gas, Karu ovens burn wood or charcoal and take a gas burner, the Fyra burns pellets and the Volt is electric. Within each family, the number or name shows the size, from 12 inch up to large Koda 2 Max models. Pick the fuel first, then the size. Ooni, the Scottish brand that helped make portable pizza ovens popular, sells a wide range with similar-looking ovens and similar names. The good news is that the names follow a pattern. Each family is defined by fuel, and each model within it by size and features. This guide maps the main families so you can narrow down quickly. Ooni updates its range often, so check uk.ooni.com for current models and specs. ## The four families by fuel Koda is Ooni's gas line. These ovens connect to a propane bottle and are the easiest to use: light, wait about 15 to 20 minutes and bake. They range from the compact Koda 12 to the Koda 2 family, which includes larger models with redesigned burners. Karu is the multi-fuel line. Out of the box, these burn wood or charcoal, and you can add an Ooni gas burner. Fyra is the pellet oven, fed from a hopper. Volt is the electric oven, designed for use indoors or outdoors with a mains socket. | Family | Fuel | Typical sizes | Best for | | --- | --- | --- | --- | | Koda | Gas | 12 inch to large Koda 2 models | Ease and speed | | Karu | Wood, charcoal, gas with burner | 12 to 16 inch | Flame flavour plus gas option | | Fyra | Wood pellets | 12 inch | Light, portable wood flavour | | Volt | Electric | 12 inch | Kitchens, covered spaces | Ooni families at a glance ## Choosing a fuel Gas is the easiest and most consistent. Wood and charcoal give real fire and smoke, but take more practice and more time. Pellets sit between the two: wood flame with less fuss than logs, though you need to keep the hopper fed. Electric removes flame and bottles entirely and is the only option for indoor use. If you are unsure, our [gas or wood-fired pizza oven](https://peelandflame.co.uk/blog/gas-or-wood-fired-pizza-oven) and [electric vs gas pizza oven](https://peelandflame.co.uk/blog/electric-vs-gas-pizza-oven) articles go through the trade-offs. ## Choosing a size Ooni's 12 inch ovens are lighter, cheaper to run and easier to store and carry. They bake one pizza at a time for one or two people. The 16 inch and larger ovens give more room to turn, bigger pizzas and space for a cast iron pan, but they are heavier and need a bigger table.

The shape helps too: Koda ovens have a gas inlet and control knob and no chimney. Karu ovens have a chimney and a fuel tray at the back. The Fyra has a hopper at the back. The Volt has a mains cable and digital controls. Knowing your model matters when buying spare stones, covers or burners, as many parts are model specific. Ooni's support pages have a guide to identifying older models. ## Accessories that work across the range Whichever Ooni you choose, the same few accessories make the biggest difference: a launching peel sized to the oven, a small turning peel, an infrared thermometer and a fitted cover for wet British weather. Ooni sells model-specific covers and stones, while peels and thermometers are interchangeable across brands. Ooni also sells mixers, pans and dough tools. They are nice to have but not essential at the start. Our [pizza oven accessories you actually need](https://peelandflame.co.uk/blog/pizza-oven-accessories-you-need) article separates the essentials from the extras. ## Where to start For most first-time buyers in a UK garden, a 12 inch gas oven is the simplest start. If you want fire, a Karu gives you wood and the option of gas later. If you live in a flat, look at the Volt or another indoor electric oven. Ooni ovens are not always listed on amazon.co.uk, so our guides include alternatives sold there.
