A Guide to Choosing Steamers


Choosing between different models and sizes of steamers should be based on the amount of food you plan to cook within the cavity at once. In addition, you’ll need to consider the space accommodations allotted for your steamer, as one model may consume a footprint within your kitchen while another can sit comfortably on top of a shelving unit.




Best for:

“The Mini” Combi Steamer

While technically a countertop model, these pint-sized steamers have the  capacity for six (3) 12" x 20" x 2 1/2" full size steam table pans or (3) 12" x 18" half size baking sheet pans.

  • Sandwiches

  • Small volume outputs (like side dishes)

  • Reconstituting foods


These can generally hold between 3-6 pans and don’t consume floor space in your kitchen. Many can be stacked if a second unit is required.

  • Small kitchens

  • Small volume outputs

  • Front of the house

Floor Model

Floor models consume floor space in your kitchen but can handle a larger output. They’re usually able to hold between 6-16 full-size pans.

Some have over-powered boilers that can also power another piece of equipment like a kettle.

  • Large kitchen

  • Large volume outputs

  • Larger items for steaming like turkey breasts

Power Source

Power Source




  • Heats items faster

  • Need room for LP tanks

  • Need natural gas hookup


  • Can be installed virtually anywhere there’s an electric and water hookup.

  • May not need a hood vent (check local regulations)

  • May not get the boiler to steam as quickly as gas models

Steam Generation

Steam units all utilize steam to cook the food within the cavity, but how that steam is created can differ based on the steam generation type you choose.

Unit Type


Best for:

Steam Generator

These stand-alone steam generators are purchased in addition to your steamer and create steam which is then directed into the steamer unit.

  • Restaurants without a boiler

  • When water isn’t potable

  • Large operations with multiple steamers or other steam-based equipment

Boilerless Steamer

These steamers generate their own steam, nullifying the need for an additional steam generator. Boilerless steamers don’t contain an enclosed boiler but rather utilizes an open water reservoir at the bottom of the unit or a spritzer which splashes cold water around the inside of the unit to create steam. The result is ‘wetter’ steam but with the benefits of easy cleanup. Remember that your foods won’t cook as fast and may not be as crisp as with other units.

  • Those without an external steam generator

  • Easier to clean and service

Boiler-Based Pressure Steamer

With an enclosed boiler, these units create their own steam and then funnel it into the cavity. You will need clean, pure water because of the risk of limescale buildup (and costly maintenance). Items typically cook faster than equivalent convection steamers.

  • Large volume outputs

  • Starchy or tough foods (like potatoes and meat)

Connectionless Steamer

The boiler for these must be manually filled and emptied each day but can save on initial costs. Remember that you will, in turn, increase your labor costs slightly.

Some newer models have an auto water feed.

  • Small operations

  • Small volume outputs

Convection vs Pressure

Along the same lines as how the steam is created is how that steam heats the food. There are two types of steamer cooking methods: convection and pressure.






Utilizes a fan to circulate heat under normal cooking pressures. The result is a lower cooking temperature (because there’s no pressure to create the extra heat).

  • Higher-Quality Results for delicate foods

  • Can open these during the steaming process to check on foods

  • Minimal taste-transfer issues

  • Ideal for steaming, poaching, thawing, stewing, reheating, and par-cooking

  • Foods take longer to cook (but still less than convection ovens)


These steamers have a tight seal which increases the temperature in the cavity to cook with a combination of high heat and steam.  Typical cabinet temperatures can get between 230 and 240 degrees fahrenheit.

  • Faster cooking times

  • Best for large batches of food

  • Works well for dense items

  • Cannot open during the steaming process to check foods

  • Higher chance for taste-transfer between batches

  • Not optimal for delicate foods

Further Reading…

Many view steamers as a cooking tool for vegetables, but the fact of the matter is that they’re ideal for vegetables as well as seafood and other tougher items. The benefits of nutrient and moisture preservation combined with fast cooking times makes it a prized niche product for many commercial kitchens.

The water quality of the incoming steam should be of top priority, as limescale buildup can wreak havoc on your system. At the same time, poor water quality can impact the flavors of the foods in the steamer unit. Investing in a water filter is essential to your steamer purchase.
