What is a space heater?

First and foremost, before we go any further, we’ll begin by looking at exactly what space heaters are. Put simply, space heaters are heaters, commonly running from mains electricity, which have been specially designed to heat up certain specific areas, as opposed to entire homes, as you would expect with central heating systems.

So for example, having a space heater in a room would be primarily for heating that specific room, making them perfect for enclosed spaces. There are many different types of space heaters currently available, which is what we’ll be looking at next, to help give an idea of some of the different and more popular models.

Different types of space heater

As mentioned, not all space heaters are the same, which is why finding the most energy efficient space heater isn’t quite as easy and as straightforward as you may have thought. Nevertheless, here’s a look at some of the different types to choose from:

Convection heaters – Convection heaters are specially designed to help them warm the air within the room they’re used in, as opposed to the people. They generate warm air which rises, as hot air does, which quickly helps to increase the temperature of the air in that room. The cool air plummets to the floor, which in turn allows the air within the room to circulate. These ones are often oil-filled.

Radiant heaters – Up next we have radiant heaters, also known as radiative heaters. These heaters are specially designed to heat up specific objects, and people, in a room, as opposed to the air. Generally they are placed directly in front of a person where they will generate heat which will then warm the person in front. They heat up almost instantaneously, so if speed is your goal, a radiant heater is ideal.

Combi heaters – Combi heaters are basically a combination of convection space heaters, and radiant space heaters as they help to distribute warm air around the room using a fan, whilst generating direct heat at the same time.

Reviews of the Top 5 Efficient Space Heaters

Dr. Infrared Heater DR968 – Small Yet Efficient

Dr. Infrared Heater Space Heater Model: DR-968


Dr. Infrared Heater DR968 can deliver more heat up to 60% while maintaining its efficiency. The advanced dual heating system generates heat and increases its flow to warm space immediately. You can barely hear the noise of this heater because its blower is engineered to produce less amount of sound perceptible to human ear.


Though this heater’s heat flow is considerably great, it takes time to warm spaces larger than 500 square feet.

Bottom Line

The Dr. Infrared Heater DR968 delivers ample amount of heat just enough to warm rooms up to 1000 square feet. You may consider this unit as your first in hand heater for its efficiency while maintaining its great heating production.

Dr. Infrared Heater is one of the neatest designs that you will see and was only recently released to the US. It is an efficient way for you to heat up your home and stay warm during the winter months. So, what makes Dr. Infrared Heater so unique? The Dual Heating System which combines PTC and Quartz element so that you have two different sources and it combines that with a high velocity blower that makes very little noise. This is one of the safest heaters around as well, and is certified by the UL in the US and Canada for maintaining high safety standards.

Performance & Features

This little heater has a lot of great features. The first is the design of the heater itself. It looks quirky, kind of like a little robot, but it is a fun design that you should be able to put in any room without making it look clunky.

Second, the price is just right for a heater of this quality. There are space heaters that are priced twice or three times as much and provide exactly the same heat. This is a great price and a quality heater as well.

In fact, since the Dr. Infrared Heater delivers sixty percent more heat than even the ‘High’ 1500 watt setting on most heaters,t it doesn’t use any more electricity than those other heaters. This is accomplished by transferring heat more efficiently.

It also has an amazing blower (not a fan) that moves more air at lower speeds than the competition. That means that you’ll get less noise.

There are three power settings so you can get the perfect temperature. There is an auto setting, a low (1000 watt) setting and a high (1500 watt) setting. You can also set the timer if you want.


The Dr. Infrared heater pretty much blows all of the other heaters on this list out of the water. There isn’t a comparison. This heater does exactly the same things that the other ones do and has an amazing price tag attached to it. The only reason to go with a more expensive heater is because you want more control over the exact temperature. With the Dr. Infrared, you have more limited options. However, it has great safety features and it does save money when it comes to energy consumption so the price makes up for the lack of control.

Safety Features

The Dr. Infrared heater is listed by Underwriter’s Laboratories in the US and in Canada. They ensure safety standards on appliances like space heaters. They have listed this one because it has no exposed heating elements or moving parts for kids and pets to get hurt on and it shuts down when it is tipped over or if it overheats.

Energy Consumption

Between 1000 and 1500 watts when it is running. However, because the heater delivers sixty percent more heat without consuming additional energy, and because of the way it transfers heat, it is more energy efficient than the average 1500 watt model.

Why choose Dr. Infrared Heater DR968?

This is a great space heater to buy and probably one of the best on the market. The price is great, it has the right safety features and it puts out more heat than others heats which means it saves you money. There really is no reason not to go with this heater.

Lasko 6435 Designer Series – The Best Bang for the Buck

Lasko 6435 Designer Series Ceramic Oscillating Heater with Remote Control


The Lasko 6435 Designer Series is creatively designed to fit with any decor on your home. It is not just design-attractive. Its oscillating feature does a very good job in heating home in wide coverage while the remote control is very helpful for ease of access.


This heater works best in an area of 100 square feet though may take a lot of time to deliver on a 300 square feet area. Also, the thermostat can only function on high setting.

Bottom Line

Although this space heater seems designed more for looks than function, it definitely works well. It can heat up a small space in a few minutes and although it doesn’t work in rooms much larger than 300 square feet, it is still a solid purchase.

From Lasko, the 6435 Designer Series oscillating space heater is one of the most attractive space heaters on the market. It is set into a wire metal basket that will match décor beautifully and it can go in any room of the house. It comes with a remote control that you can use to go through the many functions of the device and is able to heat up an entire room quickly.

Performance and Features

There is actually a lot to love about this unit. This is a space heater that looks great and functions amazingly as well. It is set into a carved iron stand that is actually very sturdy and keeps the unit from tipping, and the unit itself has an attractive, aesthetically pleasing surface.

There is no set up with this space heater. As soon as you take it out of the box it is ready to go. It is also one of the quietest units on the market and so, you can easily heat a room without affecting the look and feel of the room.

  • Fully oscillating to cover the entire room
  • Ceramic element that maintains and regulates itself
  • Overheating protection
  • Up to 1500 watts with the low setting at 900 watts
  • Adjustable thermostat (60 to 90 degrees) that regulates temperature of the room
  • Timer (1 hour to 7 hours)
  • High-Low switch
  • Full remote control


The Lasko is a decent heater when compared to the others in this group. It definitely outperforms the Dyson without any question, but what about going up against the “budget” heaters who which seem to do the same thing as this. The Lasko does have a few more features like the timer and the adjustable thermostat, but if you don’t need very specific temperature settings, you should probably go with the Dr. Infrared heater or the DeLonghi.

Safety Features

This unit has a protective internal switch that will stop it from overheating and it has a solid base that will prevent any tipping over.

Energy Consumption

There are two settings that control the energy consumption that the Lasko oscillating heater uses. The low switch uses 900 watts and the high switch uses 1500 watts.

Why choose Lasko 6435 Designer Series?

The Lasko 6435 Designer Series is a great space heater that will definitely get the job done if you have a small room that needs to be heated. It heats up fast, it heats up the entire room and it looks great no matter where you put it. But there are a couple of design flaws that customers have noticed. For one, you can’t use the thermostat unless you run the space heater on high. This might be the only way that a thermostat could be included, but it is still annoying to those who have overloaded breakers. Also, it doesn’t heat up huge rooms, but all in all this is a great space heater that you’ll get a lot of use out of.

Dyson AM05 Hot + Cool – High Performance Bladeless Heater

Dyson AM05 Hot + Cool Fan Heater, White/Silver


The Dyson AM05 works like a furnace that heats or cools entire room in no time. With Dyson’s popular bladless technology, this heater makes efficient and powerful. Likewise, this heater requires very less maintenance compared to other heaters.


This unit’s price is pretty high and may not favorable for those with a tight budget. There are heaters like Lasko 6435 Designer Series and Dr. Infrared Heater DR968 which are twice or thrice cheaper and can heat up rooms almost the same as this unit. On the other hand, the cooling feature does not perform quite well compared to heating.

Bottom Line

So, should you go ahead and get this space heater? Well it does come from a solid brand and many people have had a great deal of success with it but the price is pretty high, especially when there are other space heaters that do basically the same thing but are priced at half what the Dyson sells for. However, it does have great safety features, looks great and heats up a whole room right away.

The Dyson AM05 Hot/Cool fan heater is one of the best whole room space heaters on the market. It is able to keep you cooler in the summer months and provide heating for an entire room in the winter. The Dyson uses Air Multiplier technology to expand the heated air in all directions and it has a great deal of airflow. There are no blades, no elements and no safety issues because if this heater tips over it shuts off immediately, so you’ll never have to worry about a fire with this built-in fail-safe. Finally, it is an extremely energy efficient product, partly because of the way that it moves air.

Performance & Features

The Dyson AM05 Hot/Cool fan heater uses Air Multiplier technology with a well-designed motor to move heat much more efficiently, which means that it can heat up an entire room super fast and keep it warm even without the thermostat. It is also a cooling fan, and it can keep you from baking in the summertime by drawing in six gallons of air every second and generating high air velocity to cool the entire room. You get control over what temperature you want the room to be and over where you want the air (heated or cooled) to be directed.

Dyson AM05 has a two year warranty on the parts and labor so you’re protected if the unit fails for some reason.


Compared to the Dr. Infrared and the DeLonghi, this isn’t a great choice. It is pretty much the same heater as those two, and doesn’t have any distinguishing features that would make it worth spending the extra money on. It does heat up the entire room, but there is no reason to spend that much money on a space heater that does the same job as one that costs less than a hundred bucks. Unless you are attached to the Dyson brand, you should probably choose another product wisely.

Safety Features

Besides having no moving blades to cause injury, the Dyson AM05 also has a fail-safe that shuts off the unit completely if it gets tipped over. Those safety features added to the fact that there are no visible heating elements make this one of the safest space heaters available.

Energy Consumption

Because of how fast this unit heats up a room and because it is made to be energy efficient, this will use a great deal less electricity than most space heaters.

Why choose Dyson AM05 Hot + Cool?

Dyson AM05 is a solid product. Although it costs quite a bit more than many other space heaters on the market today it is worth the extra money because of the safety features that come with it, and the fact that it can heat up a whole room and then be shut off rather than run the space heater all day long.
