a second portion after the first portion having a lower power-consumption mode that utilizes 80% or less of the maximum power available from the one or more power circuits;

wherein the control system is further configured to generate the treatment cycle based at least in part on a received first indication of whether the power cord assemblies are coupled with two or three separate electrical power circuits of the one or more power circuits, the first indication receivable via at least one of the user device and the touch screen interface;

wherein the control system is further configured to generate the treatment cycle based at least in part on a received second indication of an amperage of the two or three separate electrical power circuits of the one or more power circuits, the second indication receivable via at least one of the user device and the touch-screen interface.

2. The heating chamber system of claim 1, further comprising the heater disposed within the enclosed heating chamber.

3. The heating chamber system of claim 1 further comprising an elongated heating assembly coupled to the heater and configured to receive the heated air from the heater and introduce at least a portion of the heated air to the enclosed heating chamber.

4. The heating chamber system of claim 3, wherein the elongated heating assembly comprises a heating tube having an air-permeable mesh strip that defines a portion of a length of the heating tube.

5. A heating chamber system for treating items infested by insects comprising:

an enclosed heating chamber;

a bottom portion defining a lower portion of the enclosed heating chamber and including a floor skirt and a floor;

a top portion defining an upper portion of the enclosed heating chamber and including a plurality of sidewalls and a roof, the top portion coupled to the floor skirt about a bottom edge of the top portion;

a collapsible architecture configured to support the top portion;

a heater disposed within the enclosed heating chamber and configured to generate and expel heated air, the heater including a heating array having four electrically isolated heating elements;

an elongated heating assembly coupled to the heater configured to receive the heated air and introduce at least a portion of the heated air to the enclosed heating chamber;

a control system disposed external to the heating chamber and operably coupled to the heater and configured to control the generation of the heated air by the heater, the control system including;

a touch-screen interface configured to present controls for the heater; and

four electrically isolated power cord assemblies configured to simultaneously provide power of a same voltage to a respective heating element of the four electrically isolated heating elements, the power of the same voltage originating from four separate outlet receptacles associated with one or more circuits having the same voltage that the power cord assemblies are respectively plugged into simultaneously, each power cord assembly of the power cord assemblies having a cord and a plug;

wherein the control system is operably connected to a remote user device via a wireless network such that the control system sends data regarding a state of the heating chamber to the user device and such that the user device sends control instructions to the control system and the control system controls the state of the heating chamber based on the control instructions received from the user device;

wherein the control system is configured to generate a heating treatment cycle based on the instructions receivable from the remote user device and the touch-screen interface, where the treatment cycle includes;

a first portion that substantially utilizes a maximum power available from the one or more power circuits that the heating chamber system draws the power from, the first portion having a duration of about 3 hours; and

a second portion after the first portion having a lower power-consumption mode that utilizes 80% or less of the maximum power available from the one or more power circuits;

wherein the control system is further configured to generate the treatment cycle based at least in part on a received first indication of whether the power cord assemblies are coupled with two or three separate electrical power circuits of the one or more power circuits, the first indication receivable via the user device and the touch-screen interface; and
