Bonfire for heating and overnight should be larger than for cooking. A bonfire for heating and spending the night should give a lot of heat and little smoke, and not vice versa. Sparks should be minimized. Fresh needles give a lot of thick smoke and very little heat. Dry needles burn quickly and give many dangerous sparks that can set fire to hair, seriously injure eyes and unprotected parts of the body. Set fire to things, clothing, fuel supplies, grass in the surrounding area, trees, and the like.

A small bonfire for heating is easier to build and maintain than a large one. Several small bonfires arranged in a circle will give more heat than one large one. The constant maintenance of fire requires significantly less effort than lighting a new fire. To extinguish a fire for the night, it is necessary to fill the coals with ash. In the morning they will still smolder. It will be easy to make and inflate the fire. Bonfire warms only those surfaces that are directly facing it. Therefore, barriers and walls are needed to reflect and retain the thermal energy of the fire. Barriers will significantly save fuel, protect the fire from attenuation, and cause smoke to rise only up. They are also protection from wind and drafts.
Natural barriers: a cliff, a large boulder, a thick trunk of a fallen tree and the like. Artificial: reflective walls, a tent, a hut and the like. Or their combination. Reflective walls can be made from any material at hand: branches, young trunks of trees or bushes, stones, tarpaulin, pieces of sheet metal. Between the sleeping place and the bonfire (if you have to sleep on the ground next to the bonfire), it is important to establish some tangible obstacle so that you do not get on fire during sleep. Drive a few short but strong stakes into the ground or lay some heavy stones. The labor costs of a person to maintain a fire and the effectiveness of the fire itself for heating depend on the options for the location of fuel on a fire.
Bonfire for heating and spending the night like Star.
Place thick logs in a circle at one end towards the center of the fire. As it burns, move the logs to the center. The bonfire burns for a long time without adding twigs and branches. Very comfortable for spending the night.
Bonfire for heating and spending the night like Hunter or Taiga.
Three long logs should be laid on a stand, a transverse short log or a large stone, connecting their ends from the side of the fire. As it burns, you need to move the logs forward and bring their burning ends together. It is convenient for small one-sided screeners from bad weather. Burns 6-8 hours without much care.
Bonfire for heating and overnight stays like Nodia.
Two thick logs are laid close to the ground. Make inward grooves in the logs. Place a kindling between them (best of all are coals from another fire). And press them on top with the third log. The bonfire flames up gradually and for a long time gives an even, steady, hot flame, which can be adjusted by spreading or shifting the lower logs.
Bonfire for heating and spending the night like Felling.
It is necessary to fold logs in the form of a log house. Intra-dilute fire. Such a fire gives a low and wide flame..
Bonfire for heating and spending the night with a suspended log.
Over the bonfire, it is safe to install a thick log so that the upper part of the flame envelops it. Support for this log: stones, soil, other logs and the like. The log will slowly burn out in the middle and will automatically (automatically) slide both halves into the fire, freeing from the need to periodically toss firewood.
Bonfire for heating and drying clothes in the ground.
Dig a small pit for a fire. Dig a recess near the fire pit so that its bottom is slightly below the level of the fire pit bottom. With a sharpened stick, punch (at an angle) the hole between these pits so that air can flow freely to the fire of the bonfire from below (blow). You can simply dig a groove to the side and cover it tightly with stones or branches from above and sprinkle with soil along the entire length.
Overlay the walls and floor of the fire pit with stones or coat with clay. Make a bonfire. Access to fire is mandatory. The greater the difference in levels between the air inlet and its exit to the fire, the greater the thrust. The air inlet level should be lower or equal to the lower fire level (coal level).
