A system for controlling the temperature of intravenous fluids according to the present invention includes a heating cabinet and a power supply cabinet. The heating cabinet includes a housing, a flexible cover and a heating plate with a generally curved configuration to uniformly heat a solution container. The cover wraps around the fluid container to secure the solution container against the heating cabinet. The heating cabinet further includes a heating controller to maintain the solution at a desired temperature. The power supply cabinet provides power to the heating cabinet and includes a display for indicating a solution temperature. A secondary power supply may be provided in the heating cabinet to facilitate heating controller operation when the heating cabinet is disengaged from the power supply cabinet. The system further monitors and provides reports of fluid temperature history.
