Buying Guide – How to Choose the Best Energy Efficient Space Heater
Selecting the right heater depends on your room size, budget, and specific heating needs. This guide explains the key factors to consider for making an informed purchase.
Heating Capacity
Check the wattage and coverage area to ensure the heater can warm your specific room size. Most efficient models offer around 1500 watts for standard indoor spaces.
Choose a unit that matches your square footage to avoid wasting energy on a unit that is too small or too large.
Thermostat Settings
A built-in thermostat allows the heater to cycle on and off automatically to maintain a set temperature. This prevents overheating and reduces electricity usage significantly.
Look for precise controls with small increments so you can fine tune your comfort without overshooting the desired warmth.
Safety Features
Essential safety features include tip-over protection and overheat sensors to prevent fires. Many modern units also have cool-to-the-touch housings for added security.
Ensure the model has ETL or UL certification to confirm it meets strict safety standards for electrical devices.
Noise Levels
For bedrooms and offices, look for heaters rated under 40 decibels. Quiet operation ensures you can sleep or focus without distraction from a loud fan.
Models with brushless DC motors often produce less noise and consume less power than standard fan designs.
Oscillation and Coverage
Oscillation helps spread heat evenly across the room rather than concentrating it in one spot. Wider angles like 70 degrees improve overall comfort.
Select a heater with oscillation if you want to warm a larger area without moving the unit manually.
Portability
Consider the weight and handle design if you plan to move the heater between rooms. Wheels are helpful for heavier units while compact designs are easier to carry.
Ensure the power cord is long enough for your outlet placement to avoid using dangerous extension cords.
Additional Features
Features like timers, remotes, and ECO modes add convenience and help save energy. These options make the heater easier to manage during long periods of use.
Decide which features are essential for your daily routine to avoid paying for extras you do not need.
Energy Efficiency
Models with ECO mode adjust power based on the room temperature to reduce consumption. This is crucial for keeping electricity bills low during winter months.
Prioritize heaters that offer automatic adjustments to maintain warmth without running at full power constantly.
How to Use and Care for Your Energy Efficient Space Heater
Always place your heater on a flat, stable surface away from flammable materials like curtains or bedding. Keep at least three feet of clearance around the unit to ensure safe airflow and operation.
Clean the intake vents regularly with a soft cloth or vacuum to remove dust. Accumulated dust can block airflow and reduce efficiency or cause the heater to overheat.
Store the heater in a dry place during warmer months and unplug it when not in use. This protects the internal components from moisture and prolongs the lifespan of the device.
Frequently Asked Questions
Are space heaters energy efficient?
Yes, many modern space heaters are highly efficient when used correctly. They focus heat directly where you are which reduces the need to heat the whole house. Look for models with ECO modes for optimal savings.
How much does it cost to run a space heater?
The cost depends on the wattage and how long you use it. Generally a 1500 watt unit costs a few cents per hour to run. Using a thermostat helps keep these costs down.
Is it safe to leave a heater on overnight?
Only leave a heater on overnight if it has specific safety features like an automatic shutoff. Most experts recommend turning it off when you sleep for maximum safety and energy savings.
What is the difference between ceramic and oil heaters?
Ceramic heaters warm up faster while oil heaters retain heat longer. Ceramic units are better for quick warmth but oil units are better for steady heat over many hours.
Do space heaters dry out the air?
Some fans may dry out the air slightly by moving air quickly around the room. Oil radiators tend to preserve humidity better than fan-based ceramic models. Use a humidifier if needed.
Can I use a space heater in a bedroom?
Yes, but ensure it has noise levels below 40 decibels for quiet sleep. Look for models with automatic safety shutoffs and cool touch exteriors for added peace of mind.
What safety certifications should I look for?
Look for ETL or UL certification to ensure the device meets safety standards. These certifications mean the product has been tested for fire and electrical safety hazards.
How often should I clean my heater?
You should clean the vents at least once a month during heavy use. Dust accumulation reduces efficiency and can become a fire hazard over time.
