 What is an Energy-Efficient Space Heater?

Energy-Efficient Space heaters are small space heaters, which require a smaller amount of electrical power to operate, and are usually placed in small to medium room spaces.  Typical energy-efficient space heaters produce between 500-1500 watts.

An energy-efficient space heater of 900 watts, if run for 60 minutes per day – 7 days a week, would cost approximately $5.00/month to operate (based on $0.18 kWh/Hr.).

Best Tower Heater: Lasko 755320 Ceramic Tower Space Heater

Lasko Oscillating Digital Ceramic Tower Heater for Home with Adjustable Thermostat, Timer and Remote Control, 23 Inches, 1500W, Silver, 755320

If you’re looking for an excellent tower heater, the Lasko 755320 Ceramic Tower Heater is a perfect option. Standing just under 23 inches tall, the Lasko 755320 is a taller tower heater that puts out the right amount of 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 does a great job in spaces of up to 350 square feet. While it isn’t made to be an independent heat source, some users even keep this heater in their garages to maintain more comfortable temperatures during winter.

Another major plus of this heater is the speed with which it can heat space. Thanks to its blower feature, it can rapidly distribute heat, allowing users to wait for less for their rooms to come up to temperature.

With its height, cool-to-the-touch exterior, and automatic timer, we also rate the Lasko tower heater as the best space 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.




Best  Oscillating Space Heater: Lasko Heater 16″ High

Lasko Designer Series Ceramic Space Heater-Features Oscillation, Remote, and Built-in Timer, Beige

Our reviews of this Lasko model show how versatile it is, and we value it for everything from heating relatively large rooms to keeping RVs warm during the cold months.

One of the few issues with the Lasko Oscillating heater is that its thermostat control is adjustable only in intervals of five degrees, making it somewhat tricky to exert precision control over the temperature in a room.

When adjusted, the controls also make a beeping sound and do not feature a volume control function. While this can be slightly obnoxious, it’s a reasonably minimal problem compared to the advantages of this heater.

Frequently Asked Questions: FAQ

What “Size” space heater do I need?

As a general rule of thumb, it is advised to have 10 watts of power for every square foot of space you’re trying to heat with a space heater.

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 is the Difference Between Ceramic and Infrared Heaters?

  • Infrared heaters can produce more heat than typical ceramic element space heaters by using a Quartz Tube or “short wave” radiant infrared heat.  Infrared heaters provide a better living and breathing environment than ceramic heaters because they radiate heat to warm objects around them.
  • Ceramic heaters are generally 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. No cleaning or maintenance is needed, with 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.  And, If you’re heating one or two small rooms, a thermostat-controlled space heater will be even more cost-effective.

Note: If you’re attempting to heat an entire house or apartment, gas energy furnaces are far more efficient than multiple space heaters, as shown here at Wikipedia.org  Electric space heaters.

Energy Cost Savings Formula for Space Heaters:

Here is a handy Cost savings formula for Space heaters: 

Using the space heater on a typical mid-range setting, it will employ about 900 Watts.

If you run the space heater 24 hours a day x 7 days a week for a month, it would cost approximately $120 (assuming the electrical cost is $0.18/kWh).

However, If you used the same setting for only 30 min a day, it would cost $2.50/month – (again, at $0.18 kWh/Hr.).  The costs of a typical 1500-watt heater would be approximately double that of a 900-watt heater.

It is vital to mention space heaters are not indeed a “high efficiency” source of heat.  This is why the appliance rating site “Energy Star” – does not rate the energy use of space heaters.

However, space heaters serve a valuable function for quick temporary heat in homes, offices, RVs, etc., and take that “chill” out of your small to medium size living space.

“Safety Features” to Consider for Space Heaters:

  • Auto shut off – In case the space heater Overheats,” the unit shuts off automatically
  • Tip Feature – If a space heater is Tipped over – this feature shuts off the space heater.
  • Thermostat – Better space heaters include a thermostat to set maximum temperature and avoid overheating a space.
  • 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 without plugging into a GFI.
  • Extension cords – Most space heaters are sold with a six-foot max. Length power cord.  This cord is specifically designed for this device to avoid overheating the cord.  Never use an extension cord or power strip with a space heater.

How To Use a Space Heater:

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.
  • If using a space heater around pets or children, consider space heaters with cool-to-the-touch surfaces.
  • Do not use space heaters near stored gasoline or combustible chemicals in a garage or basement.
  • Turn the space heater off when going to bed or leave the room for longer.
  • Always unplug the heater by grasping the plug, not the cord, when you uplug it.
  • Make sure all smoke alarms are installed and working correctly.

Do Space Heaters Work in a Garage?

Well, Yes & No.  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 want to change the temperature of your entire garage, you should look at the Best Garage heaters you can buy at Amazon. 

Garage Heaters are designed with more powerful heating capability, perfect for unheated – outdoor spaces.

How to Select the Right Heater For Your Home


How To Select Best Space Heater For Your Home | Best Home Gear
How To Select The Right Space Heater For Your Home


Before selecting the most energy-efficient space heater for your needs, you should consider a few factors. First and foremost, you need to know how ample your space is.

Many buyers select units that aren’t sufficient in size for the areas they’re trying to heat and end up – disappointed in the products they get.

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, be sure to consider the features you want. If your heater is primarily used in a bedroom, for instance, it is an excellent idea to get a remote-controlled model or one with a built-in thermostat – that can adjust without getting you out of bed.

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 pick out an energy-efficient heater that will meet your needs and perform as you need it to. Whatever your needs, there’s a good chance that one of the models on this list of the top 8 most energy-efficient space heaters will keep you toasty warm.

While we recommend the Lasko 5409 Space Heater as the Best space heater for the most significant number of users, you may find that one of the other models, like our Best Value space heater from JoyDay, is a better fit for your budget or needs.
