Commercial Combi Ovens
Choose a combi by pan capacity (6-pan countertop for cafés and retherm, 10-pan full-size for a full-service kitchen, 20-pan / roll-in for production) and boiler vs boilerless steam — a boiler makes dense steam for heavy volume but needs descaling and treated water, while boilerless is simpler and lower-maintenance. Most combis want treated water.
Compare commercial combi ovens across every brand by fuel and size. A combi runs convection, steam, or both — filter to the format and footprint you need, then compare on build. Specs are shown where the manufacturer publishes them; most combis have no published online price.
Commercial combi ovens: buying guide
A combi (combination) oven runs convection, steam, or both at once — one box that roasts, bakes, steams, retherms, and holds. They are sized by pan capacity and by boiler vs boilerless steam. Here is how to read the 67 models above.
Boiler vs boilerless
A boiler (steam-generator) combi makes dense steam fast for heavy volume, but the boiler needs descaling and treated water. A boilerless combi injects water onto a hot surface — simpler and lower-maintenance, well suited to most restaurants.
Capacity
Combis are sized by pan count: countertop 6-pan units for cafés and retherm stations, full-size 10-pan units for a full-service kitchen, and 20-pan / roll-in units for high-volume production and banquet kitchens.
Water and drainage
Because it makes steam, a combi usually wants treated/filtered water to avoid scale — a water-treatment cartridge is commonly recommended and sometimes tied to the warranty — and drains to a floor sink through an indirect, air-gapped connection.
Hood and code
Some listed combis run under a lighter Type II (condensate) hood, or in a few cases ventless, but that is set by your local mechanical code and the unit’s listing. Confirm the hood, water, and drain requirements before you set it.

Frequently asked questions
Boiler vs boilerless combi oven?
A boiler (steam-generator) combi makes steam in a separate tank for fast, dense steam and heavy volume, but the boiler needs descaling and treated water. A boilerless combi injects water onto a hot surface — simpler and lower-maintenance, well suited to most restaurants. Match to your volume and your willingness to maintain a boiler.
Do I need a hood for a combi oven?
It depends on the model and your jurisdiction. Some listed combis are approved to run under a Type II condensate hood or, in a few cases, ventless — but this is set by your local mechanical code and the unit's listing, not a universal rule. Confirm with your AHJ before you plan the line.
Does a combi oven need special water?
Usually. Because it makes steam, a combi commonly wants treated or filtered water to prevent scale, and a water-treatment cartridge is often recommended — sometimes tied to the warranty. Check the model's water-quality spec.
What can a combi oven do?
One box roasts, bakes, steams, retherms, and holds by running convection, steam, or both at once — it can replace several single-function pieces on the line, which is why capacity (pan count) is the main sizing decision.
How is a combi drained?
To a floor sink through an indirect, air-gapped connection, never a direct connection — that's a plan-review item your health department checks.
About this data
Last verified: August 2026. Specs are compiled from manufacturer spec sheets and authorized dealer listings; where a value isn't published we leave it blank rather than guess.
Methodology: every combi oven model is compared on the same set of specifications, and dimensions are checked (for sinks, overall width must exceed the combined bowl widths) — figures that fail validation are corrected from the manufacturer model number or omitted. “Street price” is the lowest legitimate published price we've found and can change.
Sourcing: product specs come from the manufacturer; regulatory statements link to the source (e.g. the FDA Food Code and NSF). Code requirements vary by jurisdiction — confirm with the authority reviewing your plans.
