Winter has come. A good friend of mine, Jane is sleeping out in the winter lean-to that has just been built in this previous post. To make these shelters more useable in cold weather a long log-fire is used along with a fire reflector. The beauty of this set-up is that a fire that is positioned one pace from your sleeping body, is as long as you are lying down (so it will kick out heat sideways down its full length), and has a reflector on the other side of the fire to reflect back what would be wasted heat – all radiates this heat back into the shelter and down on you and even behind you to keep you warm and toasty. I have slept out in around -17 celsius without a sleeping bag. Although you need to keep a strong fire going all night for this.
So here is a very short step-by-step for the fire reflector and the principle behind it.
