Melt Snow for Water Without Burning Your Fuel
Snow is water you have to pay for in fuel — here's how to cut the cost and why you should never eat it straight.
This is for educational purposes only. Not professional medical, electrical, or safety advice.
- 01
Never eat snow directly
It drops your core temperature fast and can burn your lips and gums. Melt it first — your body would pay the same energy cost with none of the hydration.
- 02
Start with liquid water
Put a cup of water in the pot first, then add snow as it heats. Snow dropped into a dry hot pan scorches and gives your water a burnt taste.
- 03
Budget the fuel
Fluffy snow is roughly 10:1 by volume (10 pots of snow for 1 pot of water); wet snow is 4–6:1. That's why melted water is a planned task, not an emergency one.
- 04
Insulate the pot
A lid plus a wool sweater or cardboard cozy around the pot cuts fuel use by a third. In sun, a black bag or solar cooker melts snow for free.
- 05
Melt ahead of the morning
Melt the night before and store it in an insulated jug wrapped in a blanket, off the floor and out of the cold. Water re-freezes faster than you can melt it at 6 a.m.
- 06
Treat it like any other water
Melting is not disinfecting. Boil snow collected near trails, animal droppings, or polluted ground, and skip discolored (yellow or pink) snow entirely.
