The best energy-efficient space heaters to keep you warm this winter

It’s time to face reality. The days are shorter. The holidays are over. The weather is colder. Winter, in all its stark glory, is fully upon us. And with the temperatures dropping and the potential for snow ever present, you’ll definitely want a cozy home to enjoy. The only problem? Your apartment has lousy heat. Or the one room your central heating system doesn’t reach is your beloved den. And bingeing on Netflix loses a bit of its luster when you’re shivering. Fortunately, you can easily remedy this situation by investing in an energy-efficient space heater.

Of course, there’s a lot to unpack when purchasing a space heater. For starters, there are two basic types from which to choose: electric and petroleum based. Petroleum-based heaters use oil, propane, natural gas, kerosene, or gasoline for power. These are often quite efficient because they burn fairly completely. This is why they are frequently used for central heating systems whenever possible. However, the downside to petroleum-based space heaters is that they require good ventilation. In fact, they must either tap into a direct vent that connects to an exhaust or be used exclusively outdoors.

Electric heaters are less efficient but typically safer and more versatile. They can also be further subdivided. For starters, you have convection heaters. These tend to be the most energy efficient, especially for large, enclosed spaces. Convection heat works by warming the surrounding air. And though it can take a little while for a room to heat up, the warmth will linger even after you turn off the device.

Conversely, you can opt for a radiant or infrared heater. These models direct heat at specific people (or objects). They warm up rather quickly. However, the hot air dissipates just as fast the minute you turn off the heater. Ceramic heaters are another option. These have the ability circulate air while focusing the heat on where it’s most needed. And they can remain cool to the touch. Finally, you can also purchase panel (or micathermic) heaters which combine both radiant and convection technology. These appliances often heat up rapidly and distribute warm air throughout the entire room.

Factors to consider

Heat Distribution – The best energy efficient heaters have the ability to quickly and evenly distribute hot air around the room. This means that they don’t just provide warmth to whichever people or objects are directly in front of them. They are designed to have a wider distribution and push air farther away. Space heaters made with oscillation systems are especially adept at this. And since they are relatively fast at heating rooms, you don’t have to use them for as long a time.

Timers – We’ve been saying it for years: timers are a great way to conserve energy. You can use them to set specific times/parameters for when your heater turns on and off. This will prevent you from running the heater unnecessarily.

Thermostats – Most energy efficient space heaters are equipped with easy-to-use thermostats. This affords you the opportunity to precisely choose the temperature you want so you don’t expend additional energy.

Programming Capabilities – Some of the more high tech heaters on the market today have programming capabilities. Hence, you can pre-set different temperatures for different times of day. Moreover, a handful of space heaters are smart devices so you can control them via your phone. All of this lets you maximize your comfort while curbing your energy output.

Automatic Shut-off – You don’t want to a space heater that will run indefinitely. Aside from being a safety risk, that’s simply not efficient or cost effective. The best heaters will automatically shut off once they’ve been running for a while. If you’re not done using it, you will need to physically turn it back on.

Overheating Safety/Kill-Switch – A growing number of space heaters are manufactured with overheat protection. Should your heater become too hot, this feature will cut power. That way you don’t have to worry about damaging your electric circuits or starting a fire, both of which we assume you would like to avoid if possible.

Portability – You can also cut down on your appliances and conserve energy by choosing a space heater that’s portable. After all, you really only need one good device that’s capable of being moved from room to room (unless you live in a massive, crowded house). Be on the lookout for lightweight heaters that are equipped with handles and/or casters.

Room Size – Certainly, you want to select a space heater whose power is appropriate for the size of the room. The higher the heat output, the more energy used. A small space might only require 750 watts of power while a larger space might need 1,500 watts. Choose a heater that will provide enough warmth for the square footage and nothing more.

Fan-Only Option – Space heaters that are made with a fan-only option offer a nice little benefit. As the seasons change and the weather gets warmer, you can then use your heater as a fan. Imagine that!

Size of Heater – As with nearly all devices, you certainly want to take size into consideration. Many people want space heaters that are relatively compact. This makes them easier to move and to store and also means that they’ll be relatively unobtrusive whenever you need to use them.

Noise – Noise is another factor you must think about. While most space heaters are relatively quiet, there is definitely a range. Some might whir or click or hum. Make sure you find a heater that’s as quiet as possible or emits a white noise that you know you’ll be able to tolerate.

Intuitive Controls – As with any piece of technology, you want to find a space heater that is simple to use. You don’t want to accidentally set your heater to the highest temperature possible and then not know how to adjust accordingly.

Before we finally delve into specific heaters, we just want to briefly touch upon a few safety issues. That’s because there are risks involved if you use these appliances improperly; they can lead to everything from burns to house fires. Therefore, it’s highly recommended that you avoid leaving the heater running in unattended rooms. Moreover, don’t leave it plugged in overnight while you’re sleeping (c’mon, have some trust in your blankets). You also shouldn’t place space heaters on a rug or near any object that’s combustible or flammable. And given their high current, they should not be used in conjunction with extension cords or power strips. Of course, you should also avoid having your heater near anything wet. That’s just common sense! We also encourage you to look for space heaters designed with a kill-switch; these machines automatically turn off should they ever accidentally tip over. Lastly, you’ll want to consider whether or not your heater has a protective housing that remains relatively cool to the touch, even after the device has been on for a while.

All right, we’ve cleared our conscience and have faith that you’ll operate your space heater safely. So now you are ready for our top picks:
