- Realism and aesthetics: Log design, flame effects, and mantles influence the visual appeal. Hand-painted logs and life-like flames enhance ambiance in living spaces.
- Safety features: Look for overheat sensors, flame supervision, and sturdy housings. Proper clearance from walls and combustibles is essential for safe operation.
- Maintenance and installation: Consider ease of installation, availability of replacement parts, and whether the unit requires professional setup or simple plug-in use.
