4. Type of Heater
There are several types of space heaters available in the market, including convection, radiant, and oil-filled heaters. Each type has its advantages and is suitable for different settings. For large rooms, convection and oil-filled heaters are often recommended as they provide consistent warmth over extended periods.
5. Portability
If you plan to move the heater from room to room, consider the weight and whether it has wheels for easy transport. A lightweight model can be a great choice for flexibility.
