- Safety Features: Look for overheat protection, automatic shut-off, tip-over guards, and water resistance (IPX ratings) to ensure safe operation in moist or outdoor environments.
- Heating Type: Infrared heaters provide direct warmth to plants and objects, which can be more energy-efficient, while fan heaters warm the air for broad coverage.
- Noise Level: Low-noise operation is preferable, especially in quiet garden or indoor settings.
- Installation Flexibility: Options to wall-mount, hang, or place heaters on the ground can cater to different greenhouse designs.
- Additional Features: Remote or app control can offer convenient operation, and multi-speed settings enable customized airflow and heat output.
