1. A system for operating computing devices, the system comprising:
a device rack for supporting one or more computing devices that output hot exhaust air;
a heating chamber having a work item rack configured to hold one or more work items;
an air-to-air heat exchanger that extracts heat from the hot exhaust air and heats air in the heating chamber;
an auxiliary heater that heats the heating chamber to a desired temperature or temperature range; and
a controller that turns on and off the auxiliary heater; modifies one or more settings of the one or more computing devices to maintain a desired heating chamber temperature range; and opens and closes one or more vents to control the amount of cold ambient air drawn into the one or more computing devices for controlling temperature within the heating chamber.
