This. Commercial stoves and ovens don't have any where near the fire safety constraints as consumer models. A typical commercial setting will include stainless steel jacketed walls, and a mandatory fire suppression system.

- The manufacturer of a commercial appliance usually won't provide a warranty for it if it's used in a residential setting. - Your homeowner's insurance probably won't cover anything related to using commercial appliances in your home. - In certain cases (probably not a washing machine, but certainly other cases like kitchen appliances), commercial equipment has different standards and codes that can be hard to accomodate for (this can be especially relevant for stoves and ovens)
