Can I use ecological logs in my wood stove?

Ecological logs are different than those found in cords of wood. You can use them, with moderation, in certain types of wood stoves. In order to use ecological logs, you must first choose a type that is compatible with your stove and be familiar with its combustion properties. By doing so, you will be able to use them without damaging your heating unit and benefit from its advantages.

What is an ecological log?

An ecological, or "dense", log is made of wood particles that are compressed to the point that they split up. The result of this process is a small log which burns quicker and generates more BTU than a traditional log.

We refer to them as ecological because they are made solely of wood residue that would otherwise have been discarded had it not been recycled to specifically make these logs. In addition, it is considered a dry wood because the humidity level contained inside the log is controlled.

Which log to choose?

Unfortunately, there are no rules that indicate the components of an ecological log. Some manufacturers sell logs containing wax. We recommend avoiding to burn wax in any wood stove or fireplace. Pay particular attention to the components before choosing your log supplier. An ecological log should contain only wood particles.

There are many types of ecological logs available on the market. The most commonly sold ecological logs measure approximately 12 inches and have grooves. These logs burn for about 2 hours and generate close to 13,000 BTU. There are also those referred to as night logs, which don't contain any grooves and are larger. These logs also generate 13,000 BTU but they burn for at least 6 hours. They are much more appropriate for EPA certified wood stoves as they resemble traditional logs (7,500 BTU in 6 hours).

How to use them?

Ecological logs are smaller and generate more heat than traditional logs. Also, they stop producing flames and reduce themselves to ashes faster than other logs. These ashes remain very hot and efficient. Caution! You may therefore add more logs in the wood stove or fireplace, generate more heat than necessary, overheat the unit and therefore seriously damage it.

The night log is much safer as it burns for 6 hours. It therefore generates less heat per hour.

Caution to be used

Many ecological log manufacturers suggest not using more than 3 logs simultaneously in an EPA certified wood stove. Wood stove and fireplace manufacturers generally don't issue warnings related to ecological logs. They are unable to do so because there is no rule or official recognition that they can rely on. The content as well as the performance of the log may vary greatly from one ecological log company to another. The only warning a manufacturer may express is a caution related to overheating. Please note that a unit that has been overheated is not covered under warranty.

Certain manufacturers, like Jotul, discourage the use of ecological logs. As they generate heat quicker, it is possible to create a thermal shock while lighting the fire, and therefore damage the unit. If you use ecological logs in a cast-iron unit, always keep the bottom full of ashes at all times and avoid lighting the stove with ecological logs.

By following these guidelines and suggestions, you should be able to choose the right log that is best suited for your needs. Ecological logs have many advantages related to storage, performance and use. When used correctly, they allow you to fully appreciate your heating unit.
