Best Electric Space Heater With Thermostat Review
How to Choose the Right Electric Space Heater with Thermostat
Understanding Heating Capacity & Room Size
The first, and arguably most important, consideration is matching the heater’s heating capacity to the size of the room. Heaters are typically rated in Watts (W) or British Thermal Units per hour (BTU). A general rule of thumb is 10 watts per square foot. So, a 150-square-foot room would ideally need a 1500W heater. However, factors like insulation, ceiling height, and window size impact this calculation. Larger rooms (over 250 sq ft) may benefit from oil-filled radiators or heaters designed for whole-room coverage, while smaller spaces (under 100 sq ft) can get by with more compact models. Choosing a heater with insufficient wattage will result in ineffective heating, while an overpowered heater can be inefficient and potentially unsafe.
Thermostat Precision & Control
A thermostat is essential for maintaining a consistent temperature and avoiding wasted energy. However, the precision of the thermostat varies significantly. Look for heaters offering 1°F or even 0.5°F increments for finer control. Some models, like the Dreo Smart Wall Heater, boast exceptionally accurate temperature settings. Features like ECO mode, which automatically adjusts heating based on room temperature, can further enhance energy efficiency. Consider if you prefer manual thermostat adjustments, digital displays, or smart features controllable via an app.
Safety Features: A Non-Negotiable
Electric space heaters, by their nature, involve potential safety risks. Prioritize models with robust safety features. Essential features include:
- Tip-Over Protection: Automatically shuts off the heater if it’s accidentally knocked over.
- Overheat Protection: Prevents the heater from reaching unsafe temperatures.
- Flame-Retardant Materials: Look for heaters constructed with V0 flame-retardant materials, as seen in the Dreo models.
- Cool-Touch Housing: Minimizes the risk of burns.
- Safety Plug: Reinforced plugs and some heaters have additional layers of safety.
Models like the Comfort Zone Baseboard Heater emphasize these features, offering peace of mind, especially in homes with children or pets.
Heating Technology & Noise Level
Different heating technologies offer different benefits.
- Ceramic Heaters: Heat up quickly and are generally more energy-efficient. Often found in portable heaters like the GiveBest Portable Ceramic Heater.
- Oil-Filled Radiators: Provide gentle, consistent heat and are known for their quiet operation. (Dreo Oil Filled Radiator)
- PTC Heaters: A type of ceramic heater known for its safety and efficiency.
Noise level is also crucial, particularly for bedrooms or offices. Some models, like the Dreo 25″ Ceramic Heater, utilize airflow designs to minimize noise to as low as 25dB. Consider the decibel rating if quiet operation is a priority.
Additional Features to Consider
- Oscillation: Distributes heat more evenly throughout the room.
- Remote Control: Offers convenient operation from a distance.
- Timer: Allows you to set the heater to turn on or off automatically.
- Smart Connectivity: Enables control via smartphone apps and voice assistants (Alexa, Google Home).
- Portability: Consider the weight and size if you plan to move the heater frequently.
