Firewood dimensions for fireplace and stove

SIZE MATTERS – THE RIGHT FIREWOOD DIMENSIONS FOR YOUR FIREPLACE

So that you can put the logs in the stove and your fireplace burns quickly and cleanly, the right length of firewood is also important. A length of 25 to 33 centimeters is usually recommended for this. In addition to the length of the firewood, you should also look at the diameter of the firewood logs that have been cut: this should not be more than 7 to 8 centimeters, as thick wood burns less well. If you have split logs that are too small, they will burn too quickly and you will have to add more wood. A correct length of firewood can certainly make it easier for you to light the fire.

When it comes to firewood, there are two firewood dimensions that are important: the diameter and the length of the logs. There is no uniform and optimal size of firewood. As a guide, the size of the firewood that fits in the fireplace is the optimal size. However, our stove owners often opt for wood with a diameter of 8 to 12 cm and a length of 25 to 33 cm. As a rule, you can equip 95% of the common fireplaces and stoves with these dimensions. Firewood in 50 cm is bought less often.

It can also happen that the logs are too long and don’t really want to fit into your fireplace. So you can say: It’s better to be too short than too long, because it would be annoying if the logs didn’t fit in the stove and had to be cut to the right size again.

LOG LENGTH AND STOVE SIZE

When it comes to the length of firewood, there are three dimensions: half a meter (50 cm), a third of a meter (33 cm) and a quarter of a meter (25 cm). Here you can choose the appropriate wood depending on the size of your fireplace.

Depending on your stove, you should choose the right log length. The opening of the oven is crucial for this. We would be happy to provide you with a rough orientation:

• Fireplace / stove with a small opening: wood length 25-30cm
• Medium opening fireplace/stove: wood length 30-33cm
• Fireplace / stove with large opening: wood length 45-50cm

If you lay out the corresponding area in the fireplace completely with firewood, then adequate air circulation cannot take place and the burning process is much slower. At the same time, there is a risk that the covered fireclay will be damaged. In this sense, too, it is advisable to tend to choose smaller logs for stoves and fireplaces. This can be distributed much better in the interior, so that the heating quality is optimized as a result.

If you have a built-in fireplace insert, the available combustion chamber is usually large enough to burn larger logs. Incidentally, it should be noted that with this type of fireplace, the air extraction is often even greater than with mobile stoves. This also promotes the burning of the logs. Large front panes are often located here, which then prevent corresponding embers from falling out. There is no risk for the fireclay to be damaged by logs that are too long.

If you, as a stove or fireplace owner, decide to heat with logs, then we recommend that you familiarize yourself with the manufacturer’s information for your device. If, according to the information, large pieces of firewood are also permitted, you can choose a log length according to your own preference. This means that a fireplace insert can generally also be heated with shorter firewood.

Theoretically, the use of different logs is possible and plays a subordinate role in the firing.

The advantages that speak for a consistent log length relate to the stacking and storage of your firewood. If your firewood is cut to different lengths, there is a risk that your painstakingly stacked stack of wood will suddenly collapse. In addition, with different lengths of wood, a certain proportion of the mostly limited stacking space is wasted because the different lengths of firewood increasingly create cavities. So: When using firewood, always make sure that the billets are of the same length.

And what about the firewood thicknesses? Different strengths bring advantages! Thinner firewood makes it easier to start the fire, and thicker wood is perfect for laying on if you want your fire to burn for a while without refilling.

However, we have another point of reference for you that relates to the ideal size: if you can grab the log with one hand, it has the ideal thickness for your stove.

The logs are easier to stack and waste of space on the property is prevented. Your log stack has more stability and you always have the certainty that all the logs fit into the combustion chamber of your stove.
