With any one of them, you will be cutting on utility costs all through the winter.

Best Energy Efficient Space Heater Reviews

1. Aikoper NT15-20A PTC Space Heater

Aikoper is a registered trademark under the company Foshan Kupo E-Commerce Co., Ltd.

It produces many electric home appliances, including barbecues, coffee machines, fans, steamers, humidifiers, and heaters.

The brand understands that it is not always smart to warm up the whole house if you only stay in a few rooms at a time.

Instead, it would be more cost-effective to run a space heater to generate soothing warmth in a more confined space.

One of Aikoper’s solutions for immediate small-space heating needs is the NT15-20A PTC space heater.

Review

Like the previous unit, the NT15-20A uses a PTC ceramic heater with an ultra-efficient fan for fast heating.

Two top dials let you control the device and make adjustments for more comfortable settings.

One dial is for an adjustable thermostat. The other is for choosing between three pre-set temperature settings: Low, Medium, and High.

These three settings run at 600 watts, 900 watts, and 1500 watts, respectively.

Aikoper brings portability to a whole new level with the NT15-20A PTC space heater.

It is so small that it measures only 6.4 by 4.8 by 9.1 inches and weighs only 2.99 pounds.

The device does not oscillate, though, which means it only occupies the same space as its dimensions.

Its fixed blowing direction also means that it only warms up a smaller space than oscillating models.

Aside from being an adjustable space heater, the Aikoper NT15-20A has a fan-only option, giving the device a total of four operation modes.

Thanks to these modes, you can use the unit to cool off during the summer instead of storing it away to collect dust in the basement until the next winter season.

Next to flexibility and adjustability, you can stay complacent with the added safety features of the Aikoper NT15-20A.

You will like that it comes with an ETL certification, ensuring its safety for everyday use.

Also, the device automatically shuts down during accidental tip-overs and power surge overheating.

What’s more, you can enjoy a good night’s sleep or a quiet, cozy time reading a book or listening to music because of its low noise output.

2. GAIATOP K-116 Portable PTC Space Heater

GAIATOP has several space heaters in its product line, but we’ll be discussing their most popular model.

Its popularity comes from its quick-warming feature, more advanced PTC heating technology, portability, and safety.

Review

GAIATOP brings a unique addition to this list.

While other space heaters seem typically bulky and unsightly, the GAIATOP K-116 space heater can bring a stylish look and a homey feel to a room.

It has a very modern appearance that any visitor can mistake for a speaker of some sort.

As a beautiful addition to interior space elements, it can even pass off as an excellent conversation starter.

The heater has a sleek, round head with three very modern wooden pegs as its legs. It fits right in with any room décor.

Without its legs, the reduced height makes it more portable than any other model on this list.

The K-116 Portable PTC is an energy-efficient unit that could make a small space more comfortable during the cold winter months.

Its ceramic heating element is ETL-listed, which means it is safe to use in any residential or office setting.

Aside from the device’s main controls, there is an independent on and off switch at the rear.

Shift between three modes using the main controls: 1000-watt high heat mode, 600-watt low heat mode, and normal blow fan mode.

The GAIATOP K-116 measures 8.1 by 6.9 by 7.3 inches and weighs only 1.61 pounds.

Its wind tunnel design uses a wide pipe’s cross-section to ensure smooth airflow and reduce heating and cooling times.

For safety, it has an automatic thermostat that enables it to shut down automatically during accidental overheating and tip-overs.

The device’s shell is made of class V0 fire-resistant material that passes UL, CE, and ROSH safety certifications.

As for functionality, any user can benefit from its flexibility.

The GAIATOP K-116 is usable both in the cold months of fall through spring. And it can even double as a simple blow fan during the summer.

This feature is a property it shares with the AUZKIN A5836 and the Aikoper NT15-20A.

Compared to those two units, though, it uses a more energy-efficient low wattage for its high heat mode.

3. Dr. Heater DR968 Portable PTC Space Heater

Dr. Heater boasts products that offer a lot more savings on electric bills with their infrared heating technology.

Space heaters from Dr. Heater combine convection heating with energy-efficient infrared heating.

Infrared heating technology heats objects within a room, unlike others that only heat the air.

Within an enclosed space, hot air rises and causes drafts that further make the area more difficult to warm.

You can attain exceptional energy efficiency by using a space heater that heats objects instead of the air around you.

This technology is at the core of the design for the Dr. Heater DR968 Portable Space Heater.

Review

The DR968 measures 17 by 12.5 by 13 inches and weighs 25 pounds.

It uses up to 1500 watts of power and comes with a six-foot-long power cord.

Using an electronic thermostat, the unit keeps the heat between 50 and 86 degrees Fahrenheit for overheat protection.

As an added safety feature, it also shuts down automatically when it tips over.

The DR968 has a front panel LED display and button controls for manual adjustments.

Even so, it also comes with infrared remote control for even more convenience.

The dimension and shape of the Dr. Heater DR968 make it look like a nightstand.

It has a natural-looking wood finish that makes it fit perfectly beside a bed, in a room’s corner as an end table, or beside a sofa.

Among all the models on this list, the Dr. Heater DR968 is the heaviest, which means it offers the best stability.

The problem is, its weight reduces portability. Dr. Heater remedies this problem by adding casters at the unit’s bottom.

With these, the DR968 fits perfectly anywhere as a small, movable piece of furniture.

You will like that when it comes to heating, the DR968 is able to heat up to 1000 square feet of space.

Impressively enough, it can provide 60 percent more heat than other 1500-watt models.

It doesn’t have an oscillatory feature like the TaoTronics TT-HE003.

Instead, it uses infrared heating technology that warms objects in the room for more cost-effective heating.

Infrared heat only comes out through a front portal above the manual controls, which means the top and the sides are safe to touch.

What’s more, the top can double as a usable flat surface.

The electronic thermostat ensures the DR968 is heating a room within the safe levels.

Thanks also to this feature, it automatically shuts down as soon as the thermostat detects a spike in temperatures.

For those conscious about their electricity consumption, Dr. Heater boasts energy savings with the DR968.

It has a very efficient energy-saving mode that automatically adjusts the heating temperature based on ambient heat.

The dual heating system that combines convection with infrared heating also makes the heating costs way cheaper than in other models.

Another perk of the DR968 is that it uses a very quiet blower fan.

It has a ball-bearing high-pressure low noise blower that only produces 39 decibels of sound.

A reading of 39 decibels means you’ll be hearing the same noise level present in a quiet library.

While energy efficiency is the focus of these reviews, you shouldn’t overlook how well it heats up a space, too.

Since the DR968 can heat a space as large as 1000 square feet, it can work as a full-room heater.

Its controls make it fully adjustable to work as a small space heater with very efficient low power usage.

Finally, the Dr. Heater DR968 has a lifetime filter, and its parts are UL-listed both in the US and Canada.

You might also like that it is proudly engineered and designed in the USA.

Though included in every purchase, many would not find the need to take advantage of the three-year warranty.

Which Is the Most Efficient Space Heater?

Among these five models, there’s no denying that the Dr. Heater DR968 is the best energy-efficient space heater.

It uses dual heating to warm a large space efficiently with the same wattage available to the other models on this list.

Moreover, it does not have to heat a whole room or basement and can double as a nightstand or a side table.

With its manual and remote controls, you can adjust the settings to match your preferences and make a tiny space feel toasty and cozy.

The problem is, it does not offer much portability.

If you want something you can carry around with you into different rooms in your house, go for the GAIATOP K-116 Portable PTC Space Heater.
