Why Choose Our Heater
At Sparks Overland, every detail is designed with performance, safety, and real-world use in mind.
1. Real Metal Fuel Tanks
We use sealed, pressure-vented stainless steel 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 Proven AUTOTERM Core
We power our heaters with the AUTOTERM Air 2D, known for its high-altitude performance, efficiency, and proven safety record. This is a heater you can trust in the mountains or the desert.
4. Premium Components
Every single part is hand-selected for reliability—from Kawasaki snowmobile fuel lines and a stainless exhaust with muffler to every fastener inside the box. We’ve scrutinized every component so you never have to.
5. Only Fresh Air
We engineered our heater to draw intake air exclusively from outside the unit—clean, fresh air. Many competitors pull air from inside their engine bay, contaminating your tent or camper with chemical odors that never go away.
6. Hand-Built Quality
We don’t mass-produce. Each unit is hand-built in Colorado by skilled craftspeople. Real people, real craftsmanship—no shortcuts.
