- Energy Efficiency: I wanted a heater that warms efficiently without skyrocketing my electricity bill, so I checked for models with adjustable thermostats and energy-saving modes.
- Portability: I preferred a heater with wheels or a handle so I could move it easily between rooms.
Features I Found Most Useful
Based on my experience, these features made a big difference:
- Adjustable Thermostat: This allowed me to set the exact temperature I wanted, helping save energy.
- Multiple Heat Settings: Having options like low, medium, and high gave me flexibility depending on how cold it was.
- Quiet Operation: Since I sometimes used the heater in my bedroom, a quieter model was important for a good night’s sleep.
- Timer Function: This helped me avoid running the heater all day and wasting power.
