SunFire Heaters will outperform torpedo-style heaters in multiple important categories. They are more quiet, virtually odorless, and have zero carbon monoxide emissions for indoor commercial applications. This improves the health and performance for you and your employees.

In addition, radiant heat is more efficient by heating people and objects directly rather than the less efficient heat transfer heating process used by forced air heaters. Our radiant heaters warm objects just like the sun and offer a breeze free and dustless heating experience.

SunFire radiant heaters produce zero up to 1 ppm of carbon monoxide when kept properly tuned. They offer a safe indoor commercial experience.

Yes. You can run on full kerosene or a mixture of both diesel and kerosene at any ratio. We do recommend adding some kerosene to your tank for starting in frigid conditions below 15 degrees since kerosene has a lower gel rate.
