Convection, Deck or Rack Oven, Which One Earns Its Space

The oven is the one piece of kitchen equipment a chef stands in front of for most of the shift. Get the type wrong and you either run out of capacity at the pass or heat a room you never fill, and you live with that mistake for years, not months.

This guide works through the real choice facing bakeries, pubs and restaurants buying an oven: deck against combi, footprint against capacity, whether you need steam injection, and what has to be in place before the installer arrives.

Match the oven to your output

Volume decides more of this than menu does. A pub adding a handful of pizzas a night has a completely different requirement from a restaurant running continuous pizza service through a Friday. Deck ovens are sized in decks, and each deck is a fixed amount of floor space you either fill or waste.

The Sammic Mini PO 1+1 Two-Deck Electric Pizza Oven gives a site two decks in a compact frame, which suits a pub or café putting pizza on the menu without needing to cook at volume all evening. Where the pizza offer is the main draw rather than a side dish, the Sammic PO-4+4 Twin Deck Electric Pizza Oven gives four decks over four, so a busier kitchen can keep several batches moving through service instead of queuing pizzas at one deck.

Footprint, stacking and rack capacity

Once a kitchen moves beyond a single-purpose oven and into combination ovens, the number that matters is grid capacity, how many GN trays the oven holds at once, set against the floor space the unit actually occupies. A ten grid combi and a twenty grid combi can sit on similar footprints depending on layout, so it is worth checking the grid count against your daily covers rather than assuming bigger case means bigger output.

The Convotherm Maxx 10 Electric Combination Oven 10 Grid suits a kitchen that needs a proper combi for roasting, baking and regeneration but does not have room, or budget, for the largest units on the market. At the other end of the range, the Convotherm 4 easyTouch Combi Oven 20 x 2/1 GN Electric holds twenty 2/1 GN trays, which is the kind of capacity that earns its space in high volume catering, contract catering or banqueting kitchens where the oven runs near constantly through service.

Steam injection and bread

Bread is where the case for steam injection is easiest to make. Steam in the first minutes of a bake keeps the crust soft long enough for the loaf to expand properly before the crust sets, which is what gives an open crumb and a good crust rather than a dense, pale one. A combi oven with steam injection does this job far more consistently than a domestic-style deck relying on ambient moisture.

The Rational iCombi Pro 10-2/1 Gas Combination Oven is worth looking at where a kitchen already has a gas supply and wants steam injection alongside general cooking versatility, roasting, baking and regeneration on the same unit rather than running separate ovens for bread and everything else. Choosing gas over electric here is mostly about what utility is already on site and what running costs suit the business, not about one fuel being the better cook.

Getting the services right before delivery day

Every oven type has a services list that has to be sorted before it arrives, and this is where installation dates slip. Electric combi ovens of any real size usually need a three-phase supply, and the exact load depends on the unit, so this has to be confirmed with an electrician against the specific model, not assumed from a similar oven you have used before. Gas ovens need a suitable gas supply and, where extraction is involved, interlocked ventilation to current gas safety requirements.

• Electrical supply confirmed against the specific oven, including three-phase where required
• Gas supply and safe extraction interlocks for gas-fired units
• Water supply and drainage for any oven with steam injection or an auto-clean cycle

Ventilation and extraction sit alongside all of this. A deck oven and a large combi both put heat and moisture into the kitchen, and the canopy has to be sized for the oven going in, not just for the space it fills on the floor.

How Advantage Catering Equipment can help

We design, supply, install and service ovens for bakeries, pubs and restaurants across Kent, and we start with output and space rather than a spec sheet. That means walking through covers, menu and footprint before recommending deck, combi or rack, and checking electrical, gas and water services against the exact model before delivery day rather than after.

If you are weighing up a deck oven against a combi, or trying to work out what grid capacity actually suits your covers, talk to us before you order. We can also handle installation and ongoing servicing so the oven keeps earning its space long after it goes in.
