Some users do complain about the heat settings, which do not correspond directly to actual temperatures, making the heater a bit hard to use for new owners. At least one review also mentions a slight problem with noise, as this heater tends to hum a bit while it runs.

AmazonBasics 500-watt Ceramic Small Space Personal Mini Heater

AmazonBasics 500-Watt Ceramic Small Space Personal Mini Heater - Black

While many reviewers commented on the high value of the Andily heater, our pick for the best value on this list has to go to the AmazonBasics 500-watt Ceramic Small Space Personal Mini Heater. This is definitely one of the most energy efficient space heaters on the market. This ultra-compact space heater is also one of the cheapest space heaters, while still delivering very good quality. Despite its seemingly small 500-watt power rating, this model is also surprisingly powerful. Key features of this product include:

500-watt power
Ceramic coil heating elements
Tip-over protection safety feature
Available in 4 colors

One of the features that stands out most in reviews of this personal space heater is its impressive heating abilities relative to its size and power rating. Several users find that it works quite well for bedrooms, offices and other small spaces. Reviewers also note its energy efficiency and value as significant advantages of this heater. Because it is available in four colors, you can even pick out a version of this unit that is visually appealing to you and which fits in well with your home decor.

While there aren’t all that many criticisms of this heater from AmazonBasics, some reviewers do note that they purchased it for uses that are beyond its abilities. While this unit will add some heat to a bedroom or office, it’s not designed to be used as a sole heat source or to warm up larger rooms or apartments. This isn’t truly a problem with the heater itself, but it is vital to understand before you decide to buy this particular model.

Best Energy Efficient Tower Heater: Lasko 5615 Ceramic Tower Heater

Lasko 5165 Digital Ceramic Tower Heater with Remote Control

If you’re looking for an excellent tower heater, the Lasko 5615 Ceramic Tower Heater is an excellent option. Standing just under 23 inches tall, the Lasko 5615 is a reasonably large tower heater that puts out a right amount of heat and doesn’t take up much floor space. Key features of this product include:

1,500-watt maximum power
Ceramic heating element
High and low thermostat settings
Automatic Timer
Blower included
Remote controllable
Comes fully assembled

Users of the Lasko 5165 find that it does a great job in spaces of up to about 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 the wintertime. Another major plus of this heater is the speed with which it can heat up space. Thanks to its blower feature, it is capable of rapid heat distribution, allowing users to wait less time for their rooms to come up to temperature.

One downside of this heater that comes out in some reviews is the fact that its oscillation feature only works when the heater is set to high. While this isn’t a huge problem, some users may prefer an oscillating tower heater that will work on any heat setting. A few users have also found the fan on this unit to be a little underpowered for their needs.

Best Oscillating Space Heater: Lasko Designer Series Ceramic Space Heater

Yet another energy efficient space heater from Lasko is the Lasko Designer Series Ceramic Space Heater. This stylish and attractive space heater has a somewhat vintage appearance to it that helps it fit nicely into almost any home decor scheme. Key features of this product include:

1,500-watt maximum power
Ceramic heating elements
Overheating protection

Reviews of this designer space heater tend to be extremely positive, with many users commenting on its overall quality, high energy efficiency, good looks, and value. User reviews of this Lasko model also show just how versatile it is, as reviewers have used it for everything from heating relatively large rooms to keeping RVs warm during the cold months.

One of the few issues that come up with this heater is the fact 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. The controls also make a beeping sound when they are adjusted 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.

Infrared heaters are great for heating up large spaces quickly, making them very popular among people who are looking for whole-house heaters.

A few buyers have found that this heater doesn’t perform quite as well in large rooms with high ceilings, as the volume of air in these rooms is more significant than in a room with a standard 8-foot ceiling. Some reviewers have also noted that the heater lacks an automatic timer, a feature which many competitive heaters do offer.

Conclusion:  Things to Keep in Mind When Buying Your Space Heater

Before you select the best energy efficient space heater for your needs, there are a few factors you should keep in mind. First and foremost, you need to know how large your space is. Many buyers select units that aren’t sufficient for the spaces they’re trying to heat and end up disappointed in the products they get as a result.

Another thing to keep in mind 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, though, it’s also worth investing in a heater with tip-over protection.

Finally, be sure to consider the features you want. If your heater is mostly used in a bedroom, for instance, it may be a good idea to get a remote controlled model that you can adjust without getting out of bed. Carefully considering the features that will be most useful to you is the best way to make sure 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 be a good fit for you. While we recommend the Lasko 5409 as the best option for the largest number of users, you may find that one of the other models we’ve reviewed here is a better fit for your unique needs and preferences.
