Steamers have a wide variety of uses from baking and roasting to warming and reheating. Steam is used as a vehicle for spreading an even heat throughout the unit, with that warmth released immediately upon contact with the food. Savings occur primarily from reductions in steam consumption in closed-system designs and in advanced open-system designs. Additional savings are possible from reductions in shell losses and improved heat transfer from gas combustion. Efficient models consume as little as 10% of the water consumed by inefficient open-system models.
The RTF has measure applications for both electric and gas steam cookers in a range of pan capacities. This measure is applicable in Idaho and Montana, and in Oregon in 2021 only. In Washington, the state appliance efficiency standard for steamers is the current ENERGY STAR Commercial Steam Cookers specification. The RTF anticipates this same standard being approved and effective in Oregon starting in 2022.
