Various exemplary devices and methods for heating fluid dispensers, hoses, and nozzles are provided. In general, the devices and methods for heating fluid dispensers, hoses, and nozzles can be configured to heat fluid dispensable by a user into a fuel tank or other type of container. In some embodiments, a fuel dispensing device can include a first passageway configured to pass fluid therethrough and can include a second passageway configured to pass heated air therethrough. The heated air passing through the second passageway can be configured to heat the fluid passing through the first passageway. In some embodiments, a fuel dispensing device can include a single hose configured to pass fluid and heated air through separate passageways therein, and the device can include a manifold configured to facilitate passage of the fluid and the heated air from separate sources into the single hose.

1. A fluid dispensing device, comprising: a hose configured to pass fluid therethrough, the hose having first and second coaxial passageways extending therethrough, the first and second coaxial passageways being configured to facilitate heating of the fluid flowing through the hose;a nozzle attached
1. A fluid dispensing device, comprising: a hose configured to pass fluid therethrough, the hose having first and second coaxial passageways extending therethrough, the first and second coaxial passageways being configured to facilitate heating of the fluid flowing through the hose;a nozzle attached to a distal end of the hose, the nozzle being configured to dispense the fluid therefrom;a nozzle boot configured to removably and replaceably seat the nozzle; anda heating element configured to heat air directed into the nozzle boot so as to allow the heated air to heat the nozzle when the nozzle is seated in the nozzle boot. 2. The device of claim 1, wherein one of the first and second coaxial passageways is configured to pass the heated air therethrough, and the other of the first and second coaxial passageways is configured to pass the fluid therethrough, the one of the first and second coaxial passageways having an exit opening oriented to direct the heated air into the nozzle boot. 3. The device of claim 1, wherein the first and second coaxial passageways are not in fluid communication with one another such that the fluid can flow through one of the first and second coaxial passageways and out of the nozzle, and the heated air can flow through the other of the first and second coaxial passageways. 4. The device of claim 1, further comprising an elongate tube having an inner lumen extending therethrough and configured to pass the heated air therethrough, the elongate tube having an exit opening oriented to direct the heated air flowing through the inner lumen into the nozzle boot. 5. The device of claim 4, wherein the first and second coaxial passageways are in fluid communication with one another and are configured to circulate the fluid therein. 6. The device of claim 5, wherein the heating element is configured to heat the fluid circulating in the first and second coaxial passageways. 7. The device of claim 4, further comprising a second elongate tube having a second inner lumen extending therethrough and configured to pass the heated air therethrough, the second elongate tube having a second exit opening oriented to direct the heated air flowing through the second inner lumen into a cabinet of the fluid dispensing device. 8. The device of claim 1, further comprising a second hose configured to pass the fluid therethrough, the second hose having third and fourth coaxial passageways extending therethrough, the third and fourth coaxial passageways being configured to facilitate heating of the fluid; a second nozzle attached to a distal end of the second hose, the second nozzle being configured to dispense the fluid therefrom; anda second nozzle boot configured to removably and replaceably seat the second nozzle therein;wherein the heating element is configured to heat air directed into the second nozzle boot so as to allow the heated air to heat the second nozzle when the second nozzle is seated in the second nozzle boot. 9. The device of claim 8, further comprising a first elongate tube having an inner lumen extending therethrough and configured to pass the heated air therethrough, the elongate tube having an exit opening oriented to direct the heated air flowing through the inner lumen into the nozzle boot; and a second elongate tube having a second inner lumen extending therethrough and configured to pass the heated air therethrough, the second elongate tube having a second exit opening oriented to direct the heated air flowing through the second inner lumen into the second nozzle boot. 10. The device of claim 9, further comprising a fan located downstream of the heating element, the fan being configured to direct the heated air into the first and second elongate tubes. 11. The device of claim 1, wherein the fluid comprises diesel exhaust fluid (DEF).
