A warming device and system for warming medical gel to a comfortable temperature prior to application to a patient. A warming chamber configured to receive one or more gel containers (e.g., packets or bottles) disposed in a horizontal orientation with a cover sealing the chamber. Multiple protrusions and/or depressions disposed on an inside surface of the chamber can be used to soften thermal conduction of heat to the gel containers and inhibit hot spots. A flexible heating element and an intermediate thermal conducting member can extend up one or more sides of the warming chamber. Multiple buttons can be used to set different gel temperature settings.
