Why Choose Our Heater
At Sparks Overland, every detail of our heater is designed with performance, safety, and real-world use in mind.
1. Real Metal Fuel Tanks
We use sealed, pressure-vented metal fuel tanks—not cheap plastic. They’re built to last, built for safety, and built for the field.
2. Warm, Protected Fuel
Our fuel tank is mounted inside the heater box, shielded from the cold. External tanks and lines are exposed to freezing temperatures—diesel can gel at just 10°F. We keep fuel warm so your heater runs when you need it most.
3. A Real Engine—Not a Toy
We power our heaters with the Velit engine for its high-altitude capability, fuel flexibility, and proven safety record. This is an engine you can trust in the mountains or the desert.
4. Premium Components
Every single part is hand-selected for reliability—from the Kawasaki snowmobile fuel lines, new exhaust with muffler, to the stainless hardware. We’ve scrutinized every component inside the box, so you never have to.
5. Only Fresh Air
We engineered our heater to draw air exclusively from outside the unit—clean, fresh air. Many competitors pull air from inside their engine bay, contaminating your tent with chemical smells that never go away.
6. Hand-Built Quality
We don’t mass-produce. Each heater takes six hours to build by skilled hands right here in Colorado. Real people, real craftsmanship—no shortcuts.
Why Gasoline?
We’ve developed the most advanced portable heating system on the market — and the first portable gasoline heater available in the U.S. No more carrying diesel just for your heater. If you already have gasoline for your vehicle, chainsaw, or other gear, you’re set.

• Up to 4X cleaner than diesel — far less carbon build-up
• Quieter operation
• Gasoline remains usable down to -40°F
