Frequently Asked Questions
WHERE CAN I PURCHASE A SUNFIRE HEATER?
You can purchase from local SunFire Dealers and retailers, various online retailers, or directly. Find all options available here or call (855) 251-1649.
ARE SUNFIRE HEATERS BETTER THAN TRADITIONAL FORCED AIR HEATERS?
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.
WHAT ABOUT CARBON MONOXIDE?
SunFire radiant heaters produce zero up to 1 ppm of carbon monoxide when kept properly tuned. They offer a safe indoor commercial experience.
CAN I USE KEROSENE?
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.
NOTE: Kerosene burns at a lower temperature so we recommend increasing fuel flow rate slightly within the fuel pump. Please view your operating manual for instructions on changing the fuel flow rate.
CAN I USE "RED DYE" DIESEL?
Yes. Red dye diesel is safe to use and covered under warranty.
WHERE DO I FIND PARTS FOR MY SUNFIRE?
CAN I REGULATE MY HEATER WITH A THERMOSTAT?
Yes. Each radiant heater is compatible to connect any standard manual or battery operated wall thermostat of your choice that can be purchased from any local hardware and many large retail stores. Connecting a thermostat is easy. For more information, review your product manual which can be found HERE.
Note: Do not use a wall thermostat that requires a 120V power source, such as a NEST, as that will damage the internal control primary.
WHAT IS THE WARRANTY?
We have a 2-year bumper to bumper limited warranty on all parts. Contact a local Dealer for support or call our free technical support line M-F 8am-4:30pm at (608) 527-9141.

WHERE DO I GO FOR SERVICE?
ARE SUNFIRE HEATERS EASY TO SERVICE MYSELF?
Yes, if you are reasonably handy with tools you should be able to handle needed repairs yourself. Our technical support department is here to help and walk you through any issues you may have. We offer free technical support for the life of you heater. Our team is available M-F 8am-4:30pm at (608) 527-9141.
WHAT CAN HELP MY HEATER START IN FRIGID CONDITIONS?
There are several things that can help these heaters start in frigid conditions below 15 degrees. The SF150 comes standard with a heated fuel filter to prevent gelling as long as it's plugged in. The heated fuel filter wrap can be purchased as an accessory for the SF80 and SF120.
We do recommend adding some kerosene to your tank and mix at any ratio with your diesel fuel as kerosene has a lower gel rate. Diesel and kerosene can be mixed at any ratio. However, kerosene does burn at a lower temperature so we recommend increasing fuel flow rate slightly within the fuel pump. Please view your operating manual for instructions on changing the fuel flow rate.
WILL SUNFIRE HEATERS WORK WITH A GENERATOR?
Yes, assuming the generator is in good working order, there is no problem and this is a common application.
If your generator hasn't been used in several months, let if run for approximately 15-20 minutes to build a proper charge in the capacitor before using your SunFire with the generator.
CAN I RUN A SUNFIRE HEATER OFF OF A CAR OR TRUCK BATTERY?
Yes, but it does require a pure sine wave inverter with a minimum capacity of 800 Watts. This type of inverter is common in many construction and trade vehicles.
