As you may know, once your fire is alight and blazing, it needs to be refuelled to maintain its heat. The burning cycle of a log is the time it takes from the kindling of the stack of firewood to transform into a layer of embers. Each cycle can ensure heating for a few hours, depending on how many logs are used, the size of the logs and how often the fire is refuelled.
It is imperative to add a few new logs to your fire at a time as oxygen entering the combustion chamber has the capability to reach all the pieces simultaneously. It is necessary to form a layer of embers that helps maintain both the heat and the burning.
To maximise the potency of your fire: Finely chopped logs crisscrossing one another burn quickly because the entering oxygen has the capability to reach all the pieces simultaneously. This arrangement of the logs is ideal for when you wish to produce more heat. Gather the embers up to the front of the grate and place at least three logs on top of them– freely crossed. Open the primary air vent until bright and blazing flames are evident. The influx of air can then be decreased slightly so that the flames do not die down.
To maintain your fire: For consistent and gradual heating, tightly packed logs in a parallel fashion will more burn slowly without a peak in temperature. To achieve a continuous stable fire, gather the embers on the grate and arrange the logs alongside one another, closely together. The compact arrangement of the logs slows dispersion of the oxygen and flames between them keeps the inner logs in the pile for later burning. Completely open the primary air vent and monitor when the logs on the outside are kindling in order to achieve the intensity of the fire that you desire.
