Cons
- Extended Heating Times: Some users have found that it can take longer than expected to reach peak temperatures, sometimes requiring multiple hours to get the room sufficiently hot.
- Airflow Management Needed: Reviewers mention that getting a vigorous burn often requires keeping the ash drawer slightly open or adjusting internal components to improve oxygen intake.
- High Fuel Consumption: Maintaining high heat levels can require a significant amount of firewood, leading some owners to note the unit's high wood usage during long sessions.
- Required Installation Adapters: For users in North America, additional flue adapters are often required to connect the unit to standard local chimney systems as the default fittings may not match.
