Key Features to Consider
When selecting a space heater, consider the size of the room and the heater's heating capacity. Look for features such as adjustable thermostats, timers, and oscillation for better heat distribution. Safety features like tip-over protection and overheat shut-off are also crucial for peace of mind.
Energy Efficiency
Energy-efficient heaters can help save on electricity bills. Look for models with energy-saving modes or those that automatically adjust their output based on the room temperature. This not only conserves energy but also prolongs the heater's lifespan.
Noise Levels
If you plan to use the heater in a bedroom or office, consider the noise levels. Some heaters operate quietly, while others may produce noticeable sounds. Reading user reviews can provide insights into how noisy a particular model is.
