a controller that selectively operates the heating element to warm the container placed on the support surface;

a first mating structure formed on an upper surface of said back wall;

a second mating structure formed on a lower surface of said back wall;

wherein the first mating structure of the modular fluid warmer is configured to mate with a second mating structure of another modular fluid warmer to stack the modular fluid warmers;

wherein the back wall of the support structure is attached to a back plate that is sized to receive the at least one modular fluid warmer; and

wherein the back plate includes a power source having a plurality of wires for connecting to each of the at least one modular fluid warmer to provide power the at least one modular fluid warmer.

2. The modular fluid warmer of claim 1 , wherein said support surface for receiving the item to be heated is essentially C-shaped.

3. The modular fluid warmer of claim 2 , wherein the support structure is an extruded piece of aluminum.

4. The modular fluid warmer of claim 1 , wherein the item is at least one of a bag and a bottle containing intravenous fluid.

5. The modular fluid warmer of claim 1 , wherein the heating element is composed of a resistive material.

6. The modular fluid warmer of claim 5 , wherein the resistive material includes silicon.

7. The modular fluid warmer of claim 1 , further comprising an optical sensor to detect placement of an item on the support surface, the optical sensor signaling to the controller that the support surface is occupied.

8. The modular fluid warmer of claim 1 , further comprising an item temperature sensor extending from the support surface for measuring a temperature of the item being heated, the item temperature sensor being connected to the controller.

9. The modular fluid warmer of claim 1 , further comprising a heating element temperature sensor that measures a temperature of the heating element, the heating element temperature sensor being connected to the controller.

10. The modular fluid warmer of claim 1 , further comprising a support surface temperature sensor that measures a temperature of the support surface, the support surface temperature sensor being connected to the controller.

11. The modular fluid warmer of claim 1 , wherein the modular fluid warmer is attached to a wall.

12. The modular fluid warmer of claim 1 , wherein the modular fluid warmer is attached to a mobile pole assembly.

13. The modular fluid warmer of claim 1 , wherein the modular fluid warmer sits on a horizontal surface.

14. The modular fluid warmer of claim 13 , wherein the modular fluid warmer docks in a countertop pedestal.

15. The modular fluid warmer of claim 1 , wherein the controller further includes a timer for measuring a time at temperature for the item being heated.

16. The modular fluid warmer of claim 15 , further comprising a display and a recall button, such that, when the recall button is pressed, the display indicates at least one of a temperature and time at temperature of the item being heated and, when the recall button is not pressed, the display indicates whether the item is received on the support surface.

17. A method of stacking a plurality of modular fluid warmers comprising:

providing a back plate sized to receive a number of modular fluid warmers, each of the modular fluid warmers configured to heat a fluid disposed in a container;

stacking the modular fluid warmers by attaching each of the modular fluid warmers to the back plate and nesting a first mating structure of one of the modular fluid warmers into a second mating structure of another of the modular fluid warmers; and

wherein the stacking of modular fluid warmers by attachment to the back plate and nesting the modular fluid warmers into one another forms a stacked assembly.

18. The method of claim 17 , further comprising adding a top portion to the stack of fluid warmers, the top portion including a power switch that turns a power to the stacked assembly on and off.

19. A transportable fluid warmer assembly comprising:

a stacked assembly including a plurality of modular fluid warmers, each of the plurality of modular fluid warmers for heating a fluid disposed in a container to a desired temperature, each of the plurality of modular fluid warmers including:

a shelf having a substantially horizontally extending support surface for supporting the container having said fluid disposed therein;

a support structure supporting said shelf and including a back wall;

a heating element proximate the support surface;

a controller that selectively operates the heating element to warm the container placed on the support surface;

a first mating structure formed on an upper surface of said back wall; and

a second mating structure formed on a lower surface of said back wall;

wherein the first mating structure of each modular fluid warmer is configured to mate with a second mating structure of another modular fluid warmer to stack the plurality of modular fluid warmers; and

an I.V. pole having the stacked assembly attached thereto.

20. The transportable fluid warmer assembly of claim 19 , wherein the I.V. pole supports the stacked assembly.
