Choosing the right type of wood for burning in fireplaces is essential for ensuring maximum combustion time and minimizing the accumulation of harmful substances like heterophen oil. While comparing the burning time and heterophen oil production, it is important to prioritize woods that produce less heterophen oil, as its accumulation can lead to fire hazards and pose health risks.

Hardwoods such as oak, walnut, willow, and mountain hair are excellent choices for fireplaces. Although they may be harder to ignite, these woods burn for a longer duration. On the other hand, evergreen trees like fir, pine, and cedar produce more smoke, resulting in the production of higher amounts of heterophen oil. These trees contain flammable aromatic resins and oils, making them suitable for fires.

It is crucial to always burn dry wood in fireplaces. Green logs that have just been cut will produce excessive smoke, especially in rooms with poor ventilation. Additionally, logs with a diameter greater than 10-12 cm should be cut into smaller pieces before using them in fireplaces.

The price of firewood can vary depending on market factors such as weather conditions and supply and demand. Therefore, it is important to purchase firewood before winter when it is in high demand.

Now that you have gained basic knowledge about the types of wood suitable for fireplaces, let's summarize the most suitable wood options:

1. Oak: Known for its density and energy, oak is often considered the "gold standard" for fireplaces. The heat value of a bundle of oak firewood ranges from 24 to 39 million BTU. It burns at a low heat but maintains a stable high temperature. Oak logs may take a year or two to completely dry, so ensure that the logs you purchase show signs of dryness, such as radial cracks, color changes, and loosening bark.

2. Douglas Fir: This type of wood is popular due to its fast growth rate, ease of splitting, and moderate and stable heat output. It is suitable for all seasons and year-round use.

3. Fruit Woods: Woods from fruit trees such as apples, cherries, and pear trees produce distinct aromas when burned. Although they have a low burning point, they generate high temperatures. The thermal energy content of each bundle of fruitwood firewood ranges from 20 to 26 million BTU. They are ideal for fireplaces and outdoor barbecue stoves due to their rich smoky and fruity flavors.

4. Birch: For mild autumn and spring weather, birch is an excellent option as it produces high flames and has a high energy content. Each bundle of birch firewood contains approximately 20 million BTUs. The moisture content should not exceed 15-20%, requiring a dry treatment process of at least three to six months. Burning birch in fireplaces creates beautiful blue flames, enhancing the visual appeal. Additionally, birch has decorative value with its silver bark, making it a great addition to home decor.

It is important to note that certain woods should never be burned in fireplaces, including chip, ivy, and lacquer trees, as they release toxic substances when burned.

By considering the characteristics and qualities of different types of wood, you can make an informed decision about the best wood to use in your fireplace. Remember to prioritize wood that produces minimal harmful substances while providing efficient and long-lasting heat.
