High Elevation(5KW) vs. Pro(2KW) Model Comparison

Both the HE (High Elevation) and Pro models feature a premium diesel heater core unit, but the HE unit is optimized for high-altitude performance with a tuned BTU output and cold air adaptations.

Which Model is Right for You?

• Pro Unit: Best for sea-level campgrounds, ground tents, rooftop tents (RTTs), and moderate heating needs. This model is more fuel-efficient at lower altitudes.
• High Elevation (HE) Unit: Built for extreme overlanding and mountainous terrain, delivering ~20% more heating output for larger spaces and sub-zero conditions.

Key Differences

• Altitude Adaptation: The HE unit features an automatic altitude sensor that activates at 3,000 ft+, adjusting performance to maintain efficiency in thin air.
• Fuel Consumption:
  • HE Unit burns more fuel per hour but heats up faster, running for shorter durations to reach the target temperature in extreme cold.

  • Pro Unit is more fuel-efficient at lower elevations, making it ideal for extended use.

     

If your adventures primarily take you to sea-level or moderate climates, the Pro is a solid choice. But for high-altitude, sub-zero expeditions, the HE model is the tougher, more capable option.
