What is an Energy-Efficient Space Heater?
Energy-efficient space heaters are small units that use less electrical power and are usually placed in small to medium rooms. Typical energy-efficient space heaters produce between 500 and 1500 watts.
An energy-efficient 900-watt space heater, if run for 60 minutes per day, 7 days a week, would cost about $5.00/month to operate (based on $0.18/kWh).

Best Tower Heater: Lasko 755320 Ceramic Tower Space Heater
The Lasko 755320 Ceramic Tower Heater is a great option if you’re looking for a top-notch tower heater.
Standing just under 23 inches tall, it is a tall tower heater with the proper heat and doesn’t take up much floor space.
Key features of this Lasko Heater include:
1,500-watt maximum power
Ceramic heating element with overheating shut-off switch
High and low thermostat settings
Automatic Timer
Blower included
Remote control
Comes fully assembled
It does not have a Tip-Over shut-off switch
Users of the Lasko 755320 find it great for spaces up to 350 square feet. While it isn’t made to be an independent heat source, some keep it in their garages to maintain more comfortable temperatures during winter.
Another major plus is how quickly it heats the space. Thanks to its blower feature, it can quickly distribute heat, so users spend less time waiting for their rooms to reach the desired temperature.
With its height, cool-to-the-touch exterior, and automatic timer, we also rate the Lasko tower heater as the best space heater for a nursery and kids’ bedrooms.
One note: The Lasko tower space heater only offers its oscillation feature when the heat temperature is high.
While this isn’t a huge problem, some users may prefer an oscillating tower heater that will work on any heat setting.
LASKO – SPACE HEATER
Best Oscillating Space Heater: Lasko 16″ High Heater
Yet another energy-efficient space heater from Lasko is the Space-Saving 16″ High Oscillating Heater. This stylish, attractive space heater is perfect for small spaces and fits well into almost any home decor scheme. Key features of this product include:
Ceramic heating elements – Only 16″ High – Oscillating Tower

Reviews of this designer space heater are generally positive, with many users praising its overall quality, energy efficiency, looks, and value.
Our reviews of this Lasko model show its versatility. We value it for heating relatively large rooms and keeping RVs warm during cold months.
One of the few issues with the Lasko Oscillating heater is that its thermostat adjusts only in five-degree intervals, making it tricky to control the room temperature precisely.
When adjusted, the controls also beep and lack a volume control. While this can be slightly obnoxious, it’s a minor issue compared to this heater’s advantages.

Best Radiant Heater – Pelonis “Oil Filled” 1500 Watt Heater
Pelonis has created one of the most popular heaters with its 1500-watt oil-filled radiant space heater.

Most Efficient Space Heater: Buyer’s Guide
Choose an Infrared Space Heater
Infrared space heaters are considered the most energy-efficient type. They convert electricity into radiant heat, directly warming objects in the room rather than heating the air first.
This means that there is less heat loss and more energy efficiency.
Benefits of using infrared space heaters:
- Energy efficiency: Infrared heaters are up to 30% more energy-efficient than other space heaters.
- Targeted heating: Infrared heaters can be directed to specific areas, so you don’t have to heat the entire room.
- Quick heating: Infrared heaters heat objects quickly, so you’ll feel warm almost immediately.
- Quiet operation: Infrared heaters are extremely quiet so they won’t disturb you.
Here are a few drawbacks of using infrared space heaters:
- Limited heating area: Infrared heaters can only heat a limited area, so they may not be suitable for large spaces.
- Not suitable for all rooms: Infrared heaters are not ideal for high ceilings or drafty rooms.
- Higher cost: Infrared heaters can be more expensive than other space heaters.
Infrared space heaters are a good choice for people seeking an energy-efficient, targeted heating solution.
However, they may not be the best choice for everyone, so consider your needs and budget before deciding.
Consider Space Heaters that Use Less Electricity
Oil-Filled Space Heaters, relatively new to the Efficient Space Heater market, use the least electricity.
An oil-filled radiant space heater, such as the Pelonis Oil-Filled heater featured in our reviews (above), is typically a 1500-watt device but consumes, on average, 20% less electricity than infrared radiant space heaters.
Frequently Asked Questions (FAQ)
What “Size” Space Heater Should I Buy?
Generally, 10 watts per square foot of space you’re trying to heat with a space heater is recommended.
For example, a 1500-watt space heater can provide a “primary heat” source for a room up to 150 square feet (10′ x 15′ room); summary: 150-square-foot room x 10 watts = 1500-watt heating requirement.
What’s the Difference Between Ceramic and Infrared Heaters?
- Infrared heaters can produce more heat than typical ceramic element space heaters by using Quartz Tubes or “short wave” radiant infrared heat.
- Because they radiate heat to warm objects around them, infrared heaters provide a better living and breathing environment than ceramic heaters.
- Ceramic heaters are less expensive than infrared heaters and typically use forced air to heat the space. Forced air heat can dry out your skin and other room objects more quickly.
- Quartz “radiant’ Infrared heaters are known for their very quiet to nearly silent heating.
- This is because many Infrared heaters don’t require a fan, which is generally the source of noise in space heaters. Infrared space heaters are an excellent choice for the bedroom or an office.
- Infrared heaters have no moving parts and require less maintenance than infrared heating units. They don’t need cleaning or maintenance, and they have no motor parts, fans, or filters.
Do Space Heaters “Save Money“?
The short answer is “Yes.” Space heaters save money for stand-alone rooms or smaller spaces. A thermostat-controlled space heater is even more cost-effective if you’re heating one or two small rooms.
Note: If you’re attempting to heat an entire house or apartment, gas furnaces are far more efficient than multiple space heaters, as shown on Wikipedia.org. Electric space heaters.
What is the Energy Cost Savings for Space Heaters?
Here is a handy cost-saving formula for Space heaters:
Using the space heater in a typical mid-range setting will employ about 900 Watts.
Running the space heater 24 hours a day, 7 days a week, for a month would cost approximately $120 (assuming an electricity cost of $0.18/kWh).
However, using the same setting for only 30 minutes daily would cost $2.50/month (again, at $0.18 kWh/hr). The cost of a typical 1500-watt heater would be approximately double that of a 900-watt heater.
It is vital to mention that space heaters are not a “high-efficiency” heat source. That is why the appliance rating site Energy Star doesn’t rate their energy use.
However, space heaters serve a valuable function for quick, temporary heat in homes, offices, RVs, etc., and can take the “chill” out of small—to medium-sized living spaces.

What are the “Safety Features” of Space Heaters?
- Auto shut off – If the space heater “Overheats,” the unit shuts off automatically.
- Tip Feature – If a space heater is tipped over, this feature shuts it off.
- Thermostat – Better space heaters include a thermostat to set the maximum temperature and prevent overheating.
- Certification—Most space heaters in the U.S. carry a certificate “label” on the device itself. Look for a UL (Underwriters Laboratory), ETL, or CSA International safety label.
- Ground fault interrupter (GFI). Do not use electric space heaters near water unless they are plugged into a GFI.
- Extension cords—Most space heaters are sold with a six-foot maximum Length power cord.
- This cord is specifically designed for this device to prevent the line from overheating. Never use an extension cord or power strip with a space heater.

How Do You Use a Space Heater Safely?
Our friends at the American Association of Appliance Manufacturers (AAAM) offer these smart “Safety Tips” for using Space Heaters:
- According to Energy.Gov, Only place portable heaters on a firm, level surface
- Establish a 3-foot perimeter “safe space” for pets or children’s safety.
- Consider space heaters with cool-to-the-touch covers when using one around pets or children.
- Do not use space heaters near stored gasoline or explosive chemicals in a garage or basement.
- Turn off the space heater before bed or when leaving the room for a while.
- Always unplug the heater by grasping the plug, not the cord.
- Make sure all smoke alarms are installed and working correctly.
Do Space Heaters Work in a Garage?
If you intend to place an indoor space heater on your workbench to take a little “chill off your boots,” energy-efficient space heaters could help.
However, if you’re serious about changing the temperature in your entire garage, check out the Best Garage heaters on Amazon.
Garage Heaters are designed with more powerful heating capability, perfect for unheated outdoor spaces.
How to Select the Right Heater For Your Home
Conclusion:
Before selecting the most energy-efficient space heater, consider a few factors. First and foremost, you need to know how much space you have.
Many buyers select units that aren’t large enough for the areas they’re trying to heat, and are disappointed with the products they receive.
Another thing to remember is the range of safety features you want. Overheating protection is essential and comes standard on almost all heaters.
If your heater will be placed in a location that receives foot traffic or if you have pets or children, it’s also worth investing in an electric space heater with tip-over protection.
Finally, consider the features you want. For instance, if your heater is primarily used in the bedroom, getting a remote-controlled model or one with a built-in thermostat that can adjust without getting you out of bed is an excellent idea.
Carefully considering the features that will be most useful to you is the best way to ensure you get a product you’re happy with.
By keeping these things in mind, you can choose an energy-efficient heater that meets your needs and performs as needed.
Whatever your needs, one of the models on this list of the top 8 most energy-efficient space heaters will likely keep you toasty warm.
While we recommend the Lasko 5409 Space Heater as the Best choice for most users, you may find that one of the other models, like our best-value space heater from JoyDay, better fits your budget or needs.
