The fireplace is capable of doing one or the other, however will not be able to do them at same time. HHV fires result in quick and hot burns that rapidly use fuel and LHV fires result in slow, stable, less intense burns that lengthen the fuel consumption. Aside from the design and model of the fireplace, the following are the most influential factors for burn times: Type of Wood Different wood types will yield longer, hotter burns, while some will yield cooler and shorter burns.
Typically, hardwoods like oak, walnut, and cherry burn longer than softwoods such as pine and fir. Moisture Content Wood with high moisture content will have less lengthy burns and very high moisture content can cause damage to the fireplace, stove, or insert. The lower the moisture content the longer burn times you will receive. Make sure to always burn only properly seasoned wood to avoid damage to the unit. Burn Settings An air damper setting that is wide open no restriction will cause the fireplace, stove, or insert to burn very hot and short as the fire is able to consume as much oxygen as it wants, therefore using all the available fuel quicker.
For longer burns, restrict the airflow to the fire to draw out the length of the fuel burning. Low airflow fires will burn at a lower BTU output for long periods whereas high airflow fires will spike with a quick rush of BTUs and quickly burn out, requiring additional wood. Installation The installation of a wood stove, fireplace, or fireplace insert can dramatically affect the burn times. Skip to content Home What type of wood burns the longest?
Ben Davis June 1, What type of wood burns the longest? What wood burns easily? What is the slowest burning wood? Do different types of wood burn differently?

How do you make logs burn slower? Why do my logs burn so fast? How many logs burn an hour? How do you make fire last longer? Why are my logs not burning? Is it safe to go to bed with a fire in the fireplace? How do you keep a fire on wet wood? As soon as the burner is lit it will start heating, start timing the process with a stopwatch. Immediately turn off the heat and note the time on the watch. Continue the timing and watch until the cube of wood extinguishes after burning completely and note the time.
Repeat with the other sample of wood and compare the times. The immediate results can be expressed in a chart which shows the time the sample takes to start burning and how long the sample takes to completely burn. If you would like to interpret the results, match the burn rates with the average growth rate for the species of wood being tested and note any correlations.
