A deck oven bakes from below and around the product through heated stone or steel decks. A convection oven bakes by moving hot air with a fan. Deck ovens suit bread, pizza and other products that need a crisp base and a strong crust. Convection ovens suit mixed menus, pastries, cookies and tray-based production. Many commercial kitchens in Singapore end up choosing on product range, floor space and utility supply, not on which type is “better”.
This guide explains how each oven works, where each one performs well, where each has limits, and what to check before ordering.
TL;DR
- Deck ovens transfer heat by conduction from a hot deck, which gives bread and pizza a crisp base and a well-developed crust.
- Convection ovens circulate hot air with a fan, which gives faster, more even tray baking for pastries, cookies, cakes and mixed menus.
- A deck oven needs more floor space and more hands-on work. A convection oven is more flexible but can dry out or darken some products if it is not managed.
- For Singapore premises, check gas or three-phase power, ventilation requirements and production volume before choosing.
- Bread-focused businesses usually start with a deck oven. Pastry and mixed-menu businesses usually start with a convection oven. Some operate both.

How the two ovens heat food
The main difference is the way heat reaches the product.
Deck oven: heat from the surface
A deck oven has one or more baking chambers, called decks. Each deck has a stone or steel floor that is heated and holds that heat. Dough sits directly on the deck, or on a peel or tray placed on it. Heat passes from the deck into the base of the product by conduction, and the heated chamber adds radiant heat from above and around it.
Because the deck stores heat, the oven recovers quickly after the door is opened and loaded. Trade coverage of deck ovens notes that they retain and conduct heat, and that this quick recovery helps a kitchen bake other menu items efficiently.
Each deck is usually controlled separately, so one chamber can run hotter than another. A bakery can bake bread in one deck and finish something that needs less heat in another.
Convection oven: heat carried by moving air
A convection oven has a fan, and often a heating element, at the back or side of the chamber. The fan moves hot air around the food. The moving air removes the cooler layer of air that forms around the product, so heat is transferred faster and more evenly across the tray or rack.
The result is that several trays can bake at once with similar colour, and baking times are often shorter than in a static-heat oven. The same air movement also dries the surface of the product, which suits crisp pastry and cookies but is less suited to a loaf that needs steam and a slow crust.
Side-by-side comparison
| Criterion | Deck oven | Convection oven |
|---|---|---|
| Main heat transfer | Conduction from stone or steel deck, plus radiant heat | Forced hot air from a fan |
| Typical products | Artisan bread, pizza, bagels, flatbreads | Pastries, cookies, cakes, croissants, mixed trays |
| Crust and base | Crisp base, strong crust | Even colour, lighter crust |
| Capacity style | Product placed directly on decks, often by hand | Several trays or racks in one chamber |
| Floor space | Larger footprint per unit of output | Generally more compact |
| Operator involvement | Higher: loading, rotating, monitoring | Lower: load trays and set the programme |
| Flexibility | Narrower product range | Wider product range |
| Heat loss when opened | Lower per deck, as each deck opens separately | Higher when large doors are opened with the fan running |
What a deck oven is good for
Deck ovens are the standard choice where the base and crust define the product.
- Artisan and sourdough bread. Direct contact with a hot deck helps the loaf rise and develop a crust. Steam injection, available on many deck ovens, adds to this.
- Pizza. A stone deck gives the base the char and crispness customers expect. The client range includes a single deck pizza oven for this use.
- Bagels, flatbreads and baguettes. These are loaded straight onto the deck and benefit from steady bottom heat.
- Kitchens that bake all day. Because the decks hold heat, the oven recovers quickly between loads, which suits a bakery with a steady flow of batches.
The deck formats most buyers consider are single deck for small shops and double deck for higher volume in the same footprint. We list a double deck oven, a double deck gas oven and a double deck gas oven with wheels for bakeries that want two chambers with separate control.
Disadvantages of a deck oven
Deck ovens have real limits, and they should be weighed before buying.
- Limited production capacity per unit. Industry guidance on pizza ovens points out that deck ovens may have limited capacity.
- Hands-on operation. The same source notes that staff must set temperatures, rotate pies and monitor the bake. A trained baker makes a visible difference.
- Space. A deck stack takes more floor area than a tray-based oven of similar daily output, which matters in a Singapore shophouse or a small central kitchen.
- Longer preheat. A stone or steel deck takes time to come to temperature, so opening-time planning matters.
- Narrow range. Delicate pastries and trays of small items are harder to manage on a deck than in a fan oven.
What a convection oven is good for
A convection oven is the more general-purpose machine.
- Pastries and cookies. Moving air gives even colour across a tray, which suits croissants, puff pastry, cookies, scones and muffins.
- Cakes and tray bakes. Several trays can bake together without the large temperature differences seen in a static oven.
- Roasting and reheating. Many kitchens use convection ovens for roast vegetables, chicken pieces, or finishing prepared dishes, so one unit serves both bakery and kitchen.
- Mixed menus and smaller sites. A cafe that bakes several items across the day can run different products without changing equipment.
Our range includes a full convection oven with four tiers, which suits tray-based baking in a compact footprint.
Disadvantages of a convection oven
The fan that makes a convection oven useful also creates its limits.
- Surface drying. Airflow can dry the outside of products that need a soft, steamed crust, including some breads.
- Uneven results if overloaded or poorly positioned. Chefs commonly report that airflow runs in one direction, so trays at the fan side can colour faster and need to be turned. Check the manufacturer’s loading guidance for your model.
- Heat loss with large doors. A multi-tray door is large, so opening it releases a lot of hot air.
- Small, light items. Light products such as thin cookies can be moved by strong airflow, so the fan speed control is worth checking.
A lower fan speed or a programmable fan setting reduces most of these problems, so ask for these features when comparing models.
Energy use: how to compare fairly
It is tempting to ask which type uses less energy. The honest answer is that it depends on load, schedule and insulation more than on the oven type alone.
The National Environment Agency (NEA) of Singapore gives guidance that applies to both. Its best practice guide on energy efficiency for food and beverage premises recommends operating baking equipment close to full load and planning production cycles so there are no long gaps between uses. It also lists insulating walls and doors, reducing gaps or openings, and using pressure controls where possible.
For a fair comparison between two quotations, use the same basis:
- Estimate the daily number of loaded hours for each oven, not the opening hours of the shop.
- Check the rated power (kW for electric, or gas consumption for gas) on each datasheet.
- Check preheat time and how many products each unit can bake per cycle.
- Check door and chamber insulation and whether the door seals well.
- Estimate how often the oven would run partly empty. A large oven used at half load wastes energy whichever type it is.
A convection oven often bakes faster at a lower temperature, which can reduce energy per tray. A deck oven with good insulation holds heat well and suits continuous production. In both cases, a unit sized to your volume matters more than the label.
Our own guides cover practical steps that need no new equipment. See five low-cost oven fixes for Singapore bakeries and the guide to cutting commercial oven energy with no capital spend.
What to check before you choose
The oven type is only part of the decision. Premises and workflow often narrow the options before the menu does.
Utilities
Confirm whether your unit has piped gas, and whether the electrical supply is single-phase or three-phase with enough capacity. The NEA guide advises checking existing utility infrastructure before selecting equipment. Many larger electric ovens need three-phase power, and a gas deck oven needs a gas connection that your landlord and licensed installer approve.
Ventilation and hood requirements
Ovens add heat and, with gas models, combustion products to the kitchen. Consult NEA and your landlord about hood and exhaust requirements for your premises before you buy, not after delivery.
Space and access
Measure the door, lift and corridor as well as the final position. Allow clearance around the oven for service and airflow. A double deck gas oven with wheels can ease cleaning access where the layout allows.
Volume and workflow
Write down peak production for your busiest day, in loaves, trays or pizzas per hour. Then check how each oven meets it:
- A deck oven suits fewer, higher-value items baked by skilled staff.
- A convection oven suits many trays handled by a smaller or less specialised team.
- If your peak is short and sharp, check preheat and recovery times.
Maintenance
Deck ovens need care for the stone or steel surface, steam system and decks. Convection ovens need fan, seal and element checks. Ask the supplier about spare parts and service response in Singapore.
Can a convection oven replace a deck oven?
Sometimes. A convection oven can bake bread, and a bakery with a mixed menu and a small amount of bread can get acceptable results, especially if the model offers steam and a low fan speed. It will not reproduce the base and crust of a stone deck for pizza or hearth-style loaves.
A deck oven can also bake pastry and cakes, but it is slower to manage for several trays of delicate items.
A practical rule:
| Your main product | Start with |
|---|---|
| Artisan bread, sourdough, pizza | Deck oven |
| Pastries, cookies, cakes | Convection oven |
| Even split of bread and pastry | One of each, or a deck oven plus a convection oven |
| Hot food as well as baking | Convection oven or combi oven |
| Very small start-up with a varied menu | Convection oven, upgrade later |
If you also cook with steam, such as roasting, regenerating or steaming, a combi oven may fit better than either. We compare the two in our guide to combi and convection ovens.
Our perspective
We supply commercial kitchen equipment to restaurants, caterers, food manufacturers and new food businesses in Singapore. The question we hear most is which oven to buy first, and the answer starts with the product, not the machine.
We advise buyers to list what they bake, in what quantity, and at what hours. If bread or pizza is the core of the business, a deck oven is the sound choice, and we would not steer that buyer towards a convection oven. If the menu is mixed or the space is small, a convection oven is usually the more practical purchase.
We also encourage buyers to look at energy at the same time. An oven sized to your volume, with good insulation, costs less to run than a larger unit running half empty. Energy-efficient models can also qualify for government grants. We guide customers through that process, so ask about eligibility before you order, not afterwards. The grant scheme’s conditions change, so confirm them on the official agency pages for your application.
We also suggest seeing the equipment in person. Door weight, deck height and control layout are easier to judge in our showroom than in a datasheet.

FAQ
Which is better, a deck oven or a convection oven?
Neither is better in general. A deck oven is better for bread and pizza, where the base and crust matter. A convection oven is better for pastries, cookies and mixed menus where flexibility and even tray baking matter.
Do deck ovens use more energy than convection ovens?
Not necessarily. Energy use depends on how full the oven is, how long it idles, and how well it is insulated. NEA guidance recommends running baking equipment close to full load and avoiding long gaps between uses, which applies to both types.
What is the main disadvantage of a convection oven?
The fan can dry the surface of products and cause uneven colour if trays are not positioned or rotated correctly. It is a poorer match for products that need a steamed, crisp hearth crust, unless the model has steam and adjustable fan speed.
Do I need both a deck oven and a convection oven?
Only if your menu has a large share of both hearth bread and tray-baked pastry. Many businesses start with the oven that suits their main product and add the second as volume grows. A single combi oven may cover mixed hot-food and baking needs in a small kitchen.
