Which Is The Most Energy-Efficient Space Heater? Six Reviews & Some Tips

Will is an avid energy efficiency guru, testing systematically to get that electricity bill down (especially in cold Canadian winters.)

Finding an Energy-Saving Space Heater in 2019: Keep Warm on a Budget

Winter is on approach, and it's getting colder. I live in a part of the world where heaters are a necessity, and it can get pretty expensive burning natural gas all winter. Sometimes central air heating isn't practical. A small, energy-efficient space heater can be the perfect thing.

That said, not all space heaters are the same. Some make use of ceramics and others make use of other technology. They're all different shapes and sizes, and some of them are a huge drain on your electrical bill each month. Some are even fire hazards!

Because it can be tough to narrow down a heater that combines good energy efficiency, low price, safe operation and small size, I'm writing an article to showcase a few good ones. We'll look at six (I've added a bonus one) of the best energy saving space heaters and give a run-down of their specs and how well they operate.

I'll also briefly touch on a couple of the popular technologies these days, so you'll understand what you're looking at! Let's begin.

Different Types of Space Heaters

There are many different types of energy efficient space heaters, and they're all subtly different. Here's a brief description of a few of the popular styles:

Convection Style

These are built to gradually increase the air temperature of the whole room, by directing warm air upwards. They work slowly, but they can fill a whole room with warmth. Some examples of this include baseboard heaters and oil and water radiators1 (despite the name, a radiator heater uses convection, not radiant heat).

Radiant Style

Radiant style heaters2 work more quickly, but they direct their temperature in a single direction. They're useful for heating up a single person or single area of a room. Most ceramic and infrared style heaters are radiant style. They're quicker, but typically use a bit more electricity.

There are also some hybrid style space heaters that are very energy efficient. They make use of a combination of the two styles I just covered.

1) Lasko: A Designer Oscillating, Energy-Saving Space Heater

  • Pros: Very powerful for its size, oscillates, attractive design
  • Cons: Doesn't retain heat, so it can cycle often

If you're after a relatively inexpensive space heater that's energy efficient and looks great, this product by Lasko might be right up your alley. It has a wide range of features and it's really user-friendly.

With up to 1500 watts of heat, this is a powerful heater in a small package. It oscillates widely on its base and has a bunch of different temperature presets on the top, as well as various fan outputs that let you control how much heat is produced and how widely it's distributed in the room. That makes it wonderful for just a single person, but it's also useful for a larger space too.

It even has a timer with settings for as long as seven hours of use.

The housing is unique among space heaters in that it looks sort of like an urn or decorative vase, definitely nothing like the sterile gray that space heaters usually come in.

The heater unit is ceramic, so this should be considered a radiant heater. With that said, it's actually pretty good at warming up a pretty big room in short order.

Because it relies on ceramic elements, it warms very quickly, but it won't maintain that warmth as long. It's good for heating up a well-insulated space quickly, but it becomes less efficient if it has to run constantly.

It is sturdy, very quiet, attractive, and doesn't tip over easily. Beyond that, it's a pretty efficient electric space heater that will last.

2) Dyson Hot + Cool: A Versatile and Powerful Heater / Fan Combination

  • Pros: Probably the most energy efficient on this list, buffet-less air, high quality build
  • Cons: Expensive compared to others on this list

You may have seen the advertisements lately extolling the virtues of the new Dyson vacuum and fan products. I've checked them out and I have to say they're living up to the hype.

They may be on the expensive side, but all Dyson products are very intelligently designed and built to be not only powerful but beautiful too.

This particular space heater and fan is efficient, energy saving, and versatile. You can use it as a heater in the cold months, and then switch it to a fan to blow cool air during the summer. No more storing it in the basement for half the year!

Their "air multiplier" technology means that the air is drawn in from around the device rather than pushed through. That results in a "buffet-less" airflow that's far more relaxing than a conventional fan.

That same air multiplier means that heat is pushed efficiently through the room, so you don't have to sit directly in front of it to gain the benefits, and it's good for heating up a decent-sized space.

It tilts and oscillates, and it's capable of projecting a huge volume of air, so it can really warm up a big space quickly. Surprisingly enough, it doesn't draw a huge amount of juice either, so your electricity bill isn't going to expand too much. It even avoids that typical space heater "burning smell" generated by dust on the elements!

Overall this is a pricey but full-featured and powerful space heater that offers energy savings to boot!
