Who else recommends it? Reviewed, TechRadar, and Good Housekeeping all picked the Dyson AM09 Hot & Cool Fan Heater.

What do buyers say? 900+ Best Buy reviewers rated this product 4 stars or above.

The Dyson Hot + Cool Jet Focus Fan Heater is one of the most expensive products on the market. This innovative, sleek model is incredibly efficient. It can heat up a room faster than other space heaters, giving it a strong edge over the competition. Yet when testing this product in the winter and summer, we found that in large rooms, the heater excels at heating a specific area rather than the entire space. This multifunctional unit operates as a heater and fan. You can easily customize the airflow to suit your needs. The Jet Focus function allows you to send air in a single direction, while the diffuse setting oscillates air throughout the room. 

This unit is jam-packed with user-friendly features to justify its high cost. It has automatic temperature maintenance, a sleep timer, and a remote that magnetically attaches to the unit. With safety features, such as a bladeless design and tip-over shutoff, it’s an ideal choice for households with children and pets. We found that even in the heating mode, the unit stays cool to the touch thanks to a buffer of cool air circulating between the thermoplastic plates and the interior ceramic plates. With all its features, we rated this design 5/5 overall.

What Our Testers Say

"Oscillation is one of the remote-controlled features and one of our favorites. The fan moves quietly along a wide arc, delivering a blast of warm air across the length of a room. It also tilts up and down, so you can direct the airflow right where you need it."Kelly Hodgkins, Product Tester

What We Like
  • Sleek design

  • Lightweight

  • Easy to use

  • Remote control for convenience

What We Don't Like
  • No automatic tip-over shutoff

  • Does not heat a large room effectively

If you’re looking to heat a small- to medium-size room, this tower-style heater stands out for its sleek design. Offering 1,500 watts or 1,000 watts of power, it’s recommended for use in rooms up to 300 square feet. The adjustable temperature ranges from 70 to 85 degrees Fahrenheit. We tested the Lasko Ceramic Heater and found it easy to use. Thanks to its slim, space-saving profile, our tester could use it almost anywhere in the house. Our tester used it multiple times a day and found the device could heat up a small bedroom in 15 minutes. We also appreciated the nice selection of features, which include oscillation, a timer, and remote control. 

The Lasko heater lacks one key safety feature: an automatic tip-over shutoff, earning a 4/5 for special features. However, the tower design is very stable, and the plastic housing remains cool to the touch when in use. While this heater did an excellent job warming up the smaller rooms, we would opt for something more powerful to heat a large open-concept living room or basement.

Best Budget: Honeywell 360 Degree Surround Heater

What We Like
  • Incredibly lightweight

  • 360-degree heat output

  • Top-mounted handle for easy carrying

  • Great selection of safety features

What We Don't Like
  • Manual dial

If you want to bring on the heat without breaking the bank, consider this affordable model from Honeywell. This small yet powerful space heater offers 750 or 1,500 watts of power to warm small to medium-size rooms. The fan blows air in a 360-degree rotation, allowing for even heat distribution. This unit relies on a manual dial to select from two power settings (low and high), along with a dial that adjusts the temperature. 

Unlike some other budget space heaters, this unit comes with an impressive array of safety features. It shuts off automatically if it tips over or overheats, and the plastic housing is cool to the touch. Other convenient features include a top-mounted handle and timer. At just over 5 pounds, this heater can be easily carried from room to room.

What We Like
  • Heats rooms evenly and efficiently

  • Can heat rooms up to 1,000 square feet

  • Great selection of safety features

What We Don't Like
  • Heater must be turned on manually

  • Remote is required to use the timer

  • A bit heavy and awkward to lift

This portable model uses a dual heating system, combining infrared heat and convection heat, to evenly warm up a large room. It has three power modes: high (1,500-watt operation), low (1,000-watt operation), and eco (which maintains the desired temperature while consuming less energy). The adjustable temperature can be set between 50 and 85 degrees. We tested the Dr. Infrared Heater and were very impressed with its performance. It was able to heat an open-concept living area and primary bedroom evenly and efficiently. Our tester wasn't a fan of its vintage look, rating the product 2/5 for appearance. With its industrial look and large heating capacity, it may be better suited for a basement. 

If you’re using the heater in a room that’s not monitored consistently, safety features are an important consideration. This unit will shut off automatically if it overheats, it tips in any direction, or the inlet air duct is obstructed. It comes with a remote control, but the heater must be turned on manually, which our tester found to be an inconvenience.

What We Like
  • Equipped with realistic-looking flames

  • Five different flame settings

  • Simple setup

  • Impressive heat that doesn't dry out skin

  • Small form factor

What We Don't Like
  • Top is too warm to display items

  • Somewhat expensive

This freestanding model from Duraflame is one of the most popular fireplace space heaters. The 3D technology creates a realistic flame effect. Features include an adjustable digital thermostat, five different flame settings, a timer, and a remote control for added convenience. The metal body of the heater is available in several different finishes, including options such as black, bronze, cream, and navy. 

Our tester used the heater in their Colorado home and found that it did an excellent job heating up smaller rooms and creating a cozy ambiance. Equipped with a 5,200 BTU infrared heater, this unit helps warm spaces up to 1,000 square feet. Thanks to a cool-touch exterior and overheat protection, this heater is safe to use around children and pets. Though the Safer Plug is a nice feature for shutting down when the unit gets too hot, our tester found the device shutting down too frequently. We also found it annoying that closing the door hid the control panel, though it does add to the unit's real-flame factor. Because the unit needs to stand on the floor and is too hot to put anything on top, our tester rated the product 3/5 for versatility.

What Testers Say

What We Like
  • Quick heating ability

  • Compact

  • Space-saving design

  • Great selection of safety features

What We Don't Like
  • Only heats areas up to 200 square feet

  • No remote control

Equipped with ceramic heating technology and a high-speed fan, the GiveBest heater can warm up a room in minutes. This model weighs just over 2 pounds and features a top-mounted handle, making it easy to carry. Measuring 8.3 x 6.3 x 4 inches, it can be placed just about anywhere in your home. In addition to providing two heat levels (1,500 or 750 watts), it can be used as a cool air fan in warmer weather. A knob control allows you to adjust the temperature. Unlike larger units, it has a fairly small coverage area—it’s designed for rooms up to 200 square feet.

The GiveBest heater has some great safety features that make it a popular pick, including an automatic tip-over shutoff and overheat protection. It’s made from flame-retardant material to avoid fire hazards.

Note that this space heater lacks some of the advanced features you’ll find on more expensive models, including a remote control and digital touchpad. However, it still delivers portable and powerful heat at an affordable price point.

What We Like
  • Powerful heat output

  • Runs without electricity

  • Can be wall- or floor-mounted

  • Electronic ignition

What We Don't Like
  • 4,500 feet altitude restriction

  • Not approved for use in California or Canada

With an extremely powerful 30,000 BTU heater, this gas-powered model can adequately warm a large area—up to 1,000 square feet. Because it doesn’t require electricity, it’s ideal for use during power outages. The lack of electricity also means you won’t see an increase in your energy bills. You have the option to mount the unit on the wall or floor (mounting brackets and fasteners are included). Some people have noticed a slight smell of fumes during operation. To err on the side of caution, use the heater in a well-ventilated area. 

Convenient features include an electronic ignition—which makes start-up a breeze—and an adjustable thermostat. The blue flame burner ensures even heat distribution. Thanks to a built-in oxygen sensor, the unit will shut off automatically if oxygen drops to a dangerous level. Take note that this product might not work above a 4,500-foot elevation. And it is not approved for use in California or Canada.

A push-button start and EZ flame adjuster make this unit easy to operate. A battery-operated siphon pump is included with the heater, allowing you to safely transfer kerosene without any spills. 

Other convenient features include easy-to-read fuel gauges, automatic shutoff, and safety grills to prevent damage to the unit. Because it runs on kerosene and no electricity is required, this heater will come in handy during a power outage.

How We Tested the Heaters

We sent top-rated heaters to different testers across the country to see how well they performed in different climates and home designs. The testers used the heaters daily for several weeks, placing the units in different rooms to test how much space they could handle. Besides the ability to heat, the testers scored the heaters for looks, volume, ease of use, and any special features like safety shut offs and remote controls. From their findings and our editors insights, we compiled this list of top heaters.

What to Look for in a Space Heater

Type

There are many types of space heaters, but the most common—and often least expensive—models are compact space heaters with fans. Other relatively safe compact space heaters have ceramic plates or coils. Models with ceramic plates are self-regulating to avoid overheating. Models with coils are often exposed and get very hot, posing a safety risk, especially to children and pets. Some floor-standing space heaters run off infrared heat or oil. Infrared heats up very quickly but does not stay hot, whereas oil models are very effective but large, heavy, and expensive.

Watts

Nearly all 120-volt space heaters are rated up to 1,500 watts at the maximum setting, which is suitable for approximately 150 square feet. Avoid models with less wattage—the price is often comparable, and they are much less effective. To heat a larger room, you’ll need to purchase multiple space heaters or consider a larger, more professional-grade heater.

Safety

Look for models with automatic shutoffs or temperature regulators, particularly if your space heater will be running frequently or overnight. Always buy models that meet U.S. safety standards. Look for labels that indicate the unit has been tested by recognized labs like UL, ETL, or CSA. And never use an extension cord with an electric heater—choose a model with a long power cord if proximity to an outlet is an issue.

FAQ
  • What kind of space heater is best?

    This will depend on the space you plan to heat, your budget, and individual needs and preferences. To choose a space heater, you first need to decide whether a convection, radiant, or combination model is right for your space. In general, convection heaters are most suited to heating entire rooms; radiant heaters warm up quickly for spot heating; and combination models are a good bet for everyday use. 

  • Do space heaters use a lot of electricity?

    Yes. Space heaters might be small and are often marketed as being energy-efficient. But most space heaters use 1,500 watts to power up, meaning that running them regularly for many hours a day will increase your energy consumption and electricity bill.   

  • Can you keep a space heater on all night?

    Overheating is a primary safety concern when using a space heater. As a general rule, space heaters should never be left unattended, making it a bad idea to leave one on all night. If you plan to keep a space heater on while you sleep, it is imperative that you choose a model that is equipped with automatic temperature regulators and shutoff features designed to protect the space heater from overheating. To eliminate risk, heat your bedroom before you go to sleep, turn off the space heater, and tuck in under a warm comforter and plenty of blankets instead.
