Why Choose Hornet Heaters?

Hornet heaters have passed all safety and certification requirements and meet ISO 8846, SAE J1171 and the USCG ignition protection standards. 

Hornet heaters are the safest and most reliable aircraft heaters on the market. They provide extremely safe engine and cockpit pre-heating, as well as, in-flight personal heating. They are manufactured with the most advanced semi-conducting, self-temperature regulating materials ever created. They do not contain conventional resistive style heating elements. It is impossible for our heaters to start a fire because the electrical resistance of the material increases as the temperature increases. Once the heating modules reach 375° F the electrical resistance approaches infinity and there is essentially no electrical flow, this is a physical characteristic of the material and is not accomplished by switches or relays.



For best results, place the heater in the cowl directly behind the prop. This will maximize the benefit of the heater and will provide easy engine starting in cold weather. 


  • Semi-Conducting, variable wattage waterproof heating modules

  • Long life, DC, ball bearing, waterproof, brushless fans

  • Waterproof DC power supplies

  • Waterproof thermostats

  • Non-conductive fire rated fiberglass housing


Each Hornet heater contains one to four of each of the following:

Hornet heaters are available in a variety of voltages: 12DC, 24DC, 120AC or 240AC. There are also many wattage options available. Our Twin Hornet models are the only heaters on the market that utilize two fans, thermostats and heating modules. This greatly reduces the possibility of a complete heater failure. The Hornet heater is built by hand in San Angelo, Texas, and has the longest warranty in the industry. You are guaranteed three years of trouble free service. 

For Pilots - 


Most pilots are aware of the excessive engine wear that may occur when a cold engine is started, but most have never considered the cold weathers effect on an aircraft’s costly avionics. A gyro goes from zero to thousands of rpms in a matter of minutes. The owner of a well known avionics shop in Oklahoma confided in me, “pre-heating of the cockpit would eliminate 50 percent of my repair work on gyros."  What effect do you think extremely low temperatures have on the expensive glass panels? I can guarantee it does not help them. Keeping a Hornet Heater in the cockpit is the best insurance you can buy to help preserve your valuable investment.
