In this video, we break down how radiant heat from a campfire works, why distance and line-of-sight matter more than flame size, and how you can dramatically improve warmth by using fire placement, thermal mass, and shelter orientation.
You’ll learn:
• What radiant heat actually is (and what it isn’t)
• Why convection heat rises and doesn’t warm you effectively
• How distance reduces radiant heat through the inverse square effect
• Why facing the fire matters
• How fire backers and thermal mass re-radiate heat
• How shelters can either block or capture radiant energy
• Practical, field-tested ways to stay warmer with less firewood
This is Part 1 of a definitive ground camping series focused on radiation, the most misunderstood heat source in cold-weather camping.
If you camp, hunt, bushcraft, or operate outdoors in winter conditions, mastering radiant heat will change how you build fires and shelters forever.
