Buying Guide – How to Choose the Best Energy Efficient Space Heater
Selecting the right heater involves evaluating several factors to ensure you get the best value and performance for your specific space.
Heating Technology
Different heaters use ceramic infrared or oil technology. Ceramic units warm up quickly and are efficient for general use while oil radiators provide steady gentle heat without a fan.
Choose ceramic for speed and oil for silent comfort in bedrooms.
Energy Efficiency Mode
Look for an ECO mode that adjusts power output based on ambient temperature. This feature prevents the heater from running at full power unnecessarily to reduce energy consumption.
Prioritize models with adaptive ECO settings for lower utility bills.
Room Size Coverage
Check the square footage rating to ensure the heater can warm your intended space effectively. Undersized units will run constantly wasting energy while oversized units may be noisy.
Match the heater rating to your room dimensions for optimal performance.
Noise Level
Noise levels vary from 25dB to over 50dB depending on the fan design. For bedrooms or offices you should seek models that operate below 40dB for quiet comfort.
Consider whisper quiet models if you need noise-free operation.
Safety Features
Always verify the unit has tip-over protection and overheat protection built in. Look for ETL or UL certification to ensure the device meets industry safety standards.
Ensure certified safety features are present before purchasing.
Controls and Remotes
Heaters with remote controls allow you to adjust settings without standing up. Digital thermostats with precise degree increments help you find the exact temperature you need.
Select units with remote control and digital thermostats for convenience.
Portability
If you need to move the heater between rooms look for lightweight designs with handles or wheels. Heavy units may be difficult to relocate frequently.
Choose portable units with handles if frequent movement is required.
Timer and Scheduling
Timers allow you to set the heater to run for specific periods or turn off automatically. This helps save energy by ensuring the heater does not run unattended.
Opt for heaters with at least an eight hour timer.
How to Use and Care for Your Energy Efficient Space Heater
Place your heater on a flat stable surface away from walls and furniture to ensure proper airflow. Keep at least three feet of clearance from curtains or bedding to prevent fire hazards.
Regularly wipe the exterior and vents with a dry cloth to prevent dust buildup. Dust can obstruct airflow and reduce efficiency over time so clean the unit monthly.
Store the heater in a dry place when not in use to protect internal components. Unplug the device before moving or cleaning it to ensure safety.
Frequently Asked Questions
Are energy efficient space heaters safer than old heaters?
Yes modern heaters often include tip-over and overheat protection that older models lacked. They also use better materials that resist fire risks compared to older electric coils.
How much electricity does a space heater use?
Most 1500 watt heaters use about 1.5 kilowatt hours per hour of use. ECO modes can reduce this consumption by adjusting output based on temperature needs.
Can I use a space heater in a bedroom?
Yes but choose a quiet model with an auto shut-off timer for safety. Ensure the unit is certified and placed away from bedding to minimize risks.
Do space heaters dry out the air?
Fan heaters may circulate dry air while oil radiators retain moisture better. If you use a fan heater consider using a humidifier to balance humidity.
What is the difference between a tower and a box heater?
Tower heaters are vertical and save floor space while box units may offer wider oscillation. Both work similarly but towers are better for tight spaces.
How do I reset my space heater?
Most units have a reset button near the plug or bottom. Press it while the unit is plugged in to restore operation after an overload.
