Why Sparks Overland?
Built the Right Way — Inside & Out
Real Metal Fuel Tank
No plastic. Ever. Our sealed, pressure-vented stainless steel fuel tank is safer, stronger, and built for long-term field use in harsh environments.
Gasoline-Optimized Fuel System
Designed specifically for gasoline operation, with premium fuel lines and filtration to ensure clean combustion, easy starting, and long service life.
A Proven ESPAR Core
Powered by the Espar Airtronic B2, widely regarded as the gold standard in gasoline air heaters. Used by OEM manufacturers, military vehicles, and professional expedition builds where failure is not acceptable.
Ultra-Quiet Magnetic Fuel Pump
Espar’s magnetic fuel pump dramatically reduces ticking noise compared to conventional solenoid pumps — making this one of the quietest gasoline heaters available, ideal for sleep-sensitive environments.
Full System Diagnostics
Advanced diagnostics and fault reporting provide real-time system insight, serviceability, and long-term reliability. This is a professional-grade heating system, not a consumer gadget.
Premium Components Only
Stainless exhaust with muffler, high-quality fuel lines, sealed electrical connectors, and carefully selected hardware throughout. Built for durability — not cost cutting.
Fresh Air Combustion Design
All combustion air is drawn from outside the unit. No fumes, no odors, and no shared cabin air.
