Devices and methods for heating fuel hoses and nozzles

A fluid dispensing system, comprising:

• a first rigid tube configured to receive, in a first inner lumen of the first rigid tube, fluid from a fluid supply;
• a second rigid tube configured to pass air therethrough in a second inner lumen of the second rigid tube;
• a flexible hose with
• a first passageway therein that is in fluid communication with the first inner lumen of the first rigid tube such that fluid in the first inner lumen is configured to flow therefrom into the first passageway, and
• a second passageway therein that is in fluid communication with the second inner lumen of the second rigid tube such that air in the second inner lumen is configured to flow therefrom into the second passageway, the second passageway being separate from the first passageway such that the air within the second passageway cannot mix with the fluid within the first passageway;
• a nozzle configured to receive the fluid from the first passageway of the flexible hose and to dispense the received fluid out of an opening of the nozzle and into a vehicle, and the nozzle being configured to receive the air from the second passageway of the flexible hose and release the air out of an opening of the nozzle;
• and
• a heat element configured to heat the air in the second passageway such that the heated air can heat fluid within the first passageway, wherein the heat element is configured to heat the air in the second passageway after the air has passed into the second passageway from the second inner lumen of the second rigid tube.

A fluid dispensing method, comprising:

• pumping unheated air from a second inner lumen of a second rigid tube into a second passageway of a flexible hose, wherein
• a first rigid tube is configured to receive, in a first inner lumen of the first rigid tube, fluid from a fluid supply,
• a first passageway in the flexible hose is in fluid communication with the first inner lumen of the first rigid tube such that fluid in the first inner lumen is configured to flow therefrom into the first passageway,
• the second passageway is in the flexible hose and is in fluid communication with the second inner lumen of the second rigid tube such that air in the second inner lumen is configured to flow therefrom into the second passageway, the second passageway being separate from the first passageway such that the air within the second passageway cannot mix with the fluid within the first passageway,
• a nozzle is configured to receive the fluid from the first passageway of the flexible hose and to dispense the received fluid out of an opening of the nozzle and into a vehicle, and the nozzle is configured to receive the air from the second passageway of the flexible hose and release the air out of an opening of the nozzle, and
• a heat element is configured to heat the air in the second passageway such that the heated air can heat fluid within the first passageway, and the heat element is disposed within and extends along a longitudinal length of the second passageway of the flexible hose such that the air in the second passageway is heated by the heat element after the unheated air enters the second passageway from the second inner lumen.
