Another important feature to consider when looking for a commercial rice cooker is whether the unit is powered by gas or electricity. Electric rice cookers are the most popular choice, but many require special voltages or their own dedicated circuits, so it is important to make sure that the rice cooker you are considering is compatible with your establishment’s wiring. Gas rice cookers need to be hooked up to a gas line, so you will need to make sure that the inlet size is correct for the size of your gas line and that you have the correct hoses and couplings for the installation.
