Amazon is where most Americans now buy space heaters, and it is also where the choice is most overwhelming. Search for “space heater” and you get hundreds of listings, many from brands that did not exist two winters ago, all promising to heat “large rooms” in seconds. The good news is that the heaters people buy again and again on Amazon tend to be the ones that actually work.
For this guide we started with Amazon’s best-selling and most-reviewed space heaters for the 2026 season, then filtered out anything without a recognized safety certification, a clear warranty or consistent owner feedback over time. We compared the rest on heating method, thermostat, oscillation, noise and value, using manufacturer specifications, independent tests and owner reviews. Looking for newer launches instead? See our guide to the best space heater 2026 models. Our Editorial Policy explains how we choose products.

1. DREO Atom One Space Heater with Thermostat
Best Overall Space Heater on Amazon
- ECO mode adjusts heat automatically
- Precise 41–95°F thermostat in 1°F steps
- 70° oscillation spreads heat across the room
- Brushless motor, rated as quiet as 37.5 dB
- Fan-forced heat, so not silent
- 12-month warranty unless you register for an extension
- Type: PTC ceramic, 1500W
- Oscillation: 70°
- Thermostat: 41–95°F
- Timer: 1–12 hours
- Safety: ETL listed, tip-over, overheat, enhanced safety plug, V-0 flame-retardant materials
- Filter: detachable
The DREO Atom One is one of the best-selling space heaters on Amazon and one of the most reviewed, and it earns that popularity. It packs a 1500W ceramic element into a small tower with 70° oscillation, so it warms a bedroom or office evenly rather than blasting one spot. The digital thermostat runs from 41 to 95°F in 1°F steps, and ECO mode lowers output on its own once the room hits your target.
Safety is handled by what DREO calls Shield360°: ETL-listed tip-over and overheat protection, an enhanced safety plug and V-0 flame-retardant materials. A brushless DC motor with nine fan blades keeps noise around 37.5 dB, and a 1–12 hour timer lets you set it and forget it. DREO’s standard warranty is 12 months, extendable to 30 months when you register the product.
Who the DREO Atom One fits best
Most buyers who want one proven, well-reviewed heater for a bedroom, home office or small living room at a mid-range price.
Who should skip the DREO Atom One
If you want completely silent heat for sleeping, choose the De’Longhi oil-filled radiator. For a big open room, the Dr. Infrared DR-968 has more reach.

2. Lasko 751320 Ceramic Tower Space Heater
Most Trusted Tower Heater
- A best seller on Amazon for many seasons
- Adjustable thermostat and 7-hour timer
- Wide oscillation and remote control
- 3-year limited warranty
- Only two heat settings
- No ECO or auto mode
- Type: 23-inch ceramic tower, 1500W
- Heat: 2 settings + adjustable thermostat
- Timer: up to 7 hours
- Safety: ETL listed, self-regulating ceramic element, overheat protection, cool-touch housing
- Warranty: 3-year limited
Lasko has been making heaters since 1906, and the 751320 tower is one of the longest-running best sellers in Amazon’s space heater category. Its appeal is simple: a slim 23-inch tower that oscillates widely, warms a medium-size room with 1500 watts of ceramic heat and stays cool to the touch on the outside.
Controls are basic but complete. You get two heat settings, an adjustable thermostat, a timer of up to seven hours and a remote. Safety includes a self-regulating ceramic element, overheat protection and ETL certification. The 3-year limited warranty is longer than most rivals in this price range, which helps explain why so many buyers keep choosing it.
Who the Lasko 751320 fits best
Buyers who want a familiar brand, a long warranty and straightforward controls for a bedroom or living room.
Who should skip the Lasko 751320
If you want a precise digital thermostat with an ECO mode, the DREO Atom One or DREO 24-inch tower offers more control for similar money.

3. Amazon Basics 1500W Ceramic Space Heater
Best Budget Pick on Amazon
- Very low price
- High (1500W), Low (900W) and fan-only settings
- Tip-over and overheat protection
- Light at about 3 lb
- No digital thermostat or timer
- Not for bathrooms or damp rooms
- Type: ceramic, 1500W / 900W
- Modes: high, low, fan only
- Noise: about 43 dB
- Size: 7.5 x 6.3 x 9.5 in
- Safety: tip-over and overheat protection, power indicator light
Amazon’s own Basics ceramic heater is one of the most purchased space heaters on the site, mainly because it does the essentials for a very low price. It offers two heat levels, 1500W and 900W, plus a fan-only mode, in a compact box small enough for a desk or the floor next to your chair.
There is no digital thermostat, remote or timer, so you manage comfort by switching settings yourself. Safety covers the basics with tip-over and overheat protection and a power indicator light. Amazon rates the noise at about 43 dB, a little louder than DREO’s brushless models. Amazon also warns against using it in bathrooms, laundry rooms or other humid spaces.
Who the Amazon Basics heater fits best
Anyone who needs an inexpensive heater for a desk, dorm or small room and does not need smart features.
Who should skip the Amazon Basics heater
If you want a thermostat that holds a set temperature, spend a little more on the DREO compact heater. For more budget options, see our guide to the best budget space heater.

4. Dr. Infrared DR-968 Portable Space Heater
Best Best-Selling Infrared Heater
- Infrared quartz plus PTC heat for large rooms
- Electronic thermostat and 12-hour timer
- Quiet blower at about 39 dB
- 3-year warranty
- Heavy at about 19 lb
- Draws 12.5 amps, so give it its own outlet
- Type: infrared quartz + PTC, 1500W
- Heat output: about 5,200 BTU
- Thermostat: electronic, with Eco mode
- Timer: 12 hours
- Safety: tip-over and overheat protection
- Weight: about 19 lb, casters
The Dr. Infrared DR-968 has been one of Amazon’s top infrared heaters for years. It combines an infrared quartz tube with a PTC element and a high-pressure, low-noise blower rated at about 39 dB. The result is heat that reaches across a large room and feels gentle rather than blasting and drying.
An electronic thermostat with an auto energy-saving mode, a 12-hour shut-off timer and a remote make it easy to live with. At about 19 pounds it is heavy, but casters let you roll it between rooms. It draws 12.5 amps on high, so plug it into an outlet that does not share a circuit with other big appliances. A 3-year warranty adds confidence.
Who the Dr. Infrared DR-968 fits best
Large living rooms, basements and drafty older homes where a small ceramic heater cannot keep up.
Who should skip the Dr. Infrared DR-968
For a small bedroom or office, a lighter ceramic heater like the DREO Atom One is a better fit and costs less.

5. DREO Compact Space Heater with Thermostat
Best Small Heater with a Real Thermostat
- Digital thermostat from 41 to 95°F in 1°F steps
- ECO, power heat and fan-only modes
- Quiet 34 dB brushless motor
- Tilt-detection sensor for tip-over protection
- No oscillation
- Small footprint limits reach in big rooms
- Type: PTC ceramic, 1500W
- Modes: power heat, ECO, fan only
- Thermostat: 41–95°F
- Noise: as low as 34 dB
- Safety: tilt-detection tip-over sensor, overheat protection, child lock, V0 flame-retardant materials
- Weight: about 3 lb
This compact DREO heater is one of the most popular small heaters on Amazon, and it is the step up we recommend from the bare-bones budget models. It weighs about 3 pounds, has a carry handle and still puts out a full 1500 watts through a redesigned heat funnel that DREO says throws warm air much farther than older small heaters.
The real advantage is the thermostat. You can set any temperature from 41 to 95°F in 1°F steps and let ECO mode hold it, which avoids the on-off blasts of simpler heaters. A brushless motor keeps it as quiet as 34 dB, and safety features include a tilt-detection sensor, overheat protection, a child lock and V0 flame-retardant materials.
Who the DREO compact heater fits best
Bedrooms, dorms and home offices where you want quiet, steady heat and precise temperature control for under the price of a tower heater.
Who should skip the DREO compact heater
It does not oscillate, so if you need to warm a whole living room, the DREO 24-inch tower or Atom One spreads heat more widely.

6. DREO 24-Inch Oscillating Tower Heater
Best Best-Selling Tower for Bedrooms
- Very quiet at about 34 dB
- ECO mode switches between 1000W and 1500W
- 70° oscillation with a smooth trackball mechanism
- 12-hour timer and 24-hour auto shut-off
- Larger and pricier than compact heaters
- Fan-forced heat can dry the air
- Type: PTC ceramic tower, 1500W
- Oscillation: 70°
- Thermostat: 41–95°F with ECO mode
- Noise: about 34 dB
- Timer: 12 hours, plus 24-hour auto-off
- Safety: ETL, tip-over, overheat, V0 flame-retardant materials
DREO’s 24-inch tower is another long-time Amazon favorite and the tower we would choose for a bedroom. It is rated at about 34 dB, close to library-quiet, thanks to an oblique airflow fan design. A trackball oscillation system sweeps 70° and is rated for more than 750,000 cycles.
ECO mode uses a built-in temperature sensor to switch between 1000W and 1500W as needed to hold your set temperature. A 12-hour timer covers bedtime, and the heater also turns itself off after 24 hours without interaction. Safety features include tip-over and overheat protection, V0 flame-retardant materials and ETL certification.
Who the DREO 24-inch tower fits best
Light sleepers and anyone who wants a quiet tower heater with a real thermostat for a bedroom or living room.
Who should skip the DREO 24-inch tower
If you want zero fan noise, an oil-filled radiator like the De’Longhi is completely silent. For more bedroom options, see the best space heater for bedroom guide.

7. De’Longhi ComfortTemp Oil-Filled Radiator
Best-Selling Oil-Filled Radiator
- No fan, so completely silent
- ComfortTemp mode is up to 20% more efficient
- Gentle heat that does not stir up dust
- Wheels and handle for moving between rooms
- Slow to warm a cold room
- Heavy at about 23 lb
- Type: oil-filled radiator, 1500W
- Controls: power level and adjustable thermostat
- Energy mode: ComfortTemp
- Design: thermal slot fins with low surface temperature
- Warranty: 3 years
- Weight: about 23 lb
De’Longhi’s oil-filled radiator is the best-selling heater of its kind on Amazon. Oil-filled radiators have no fan; they heat sealed oil inside the fins, which then radiates warmth into the room. That makes them completely silent and gentle on allergies, since nothing blows dust, pollen or pet dander around.
The ComfortTemp feature automatically picks a temperature and power level, which De’Longhi says is up to 20% more efficient than running the thermostat at maximum. Its thermal slot design pushes more heat into the room while keeping the surface cooler. Built-in wheels and a handle help you move it, which matters because it weighs about 23 pounds. Expect it to take longer to warm a cold room than a ceramic heater, but it holds steady heat well once it gets there.
Who the De’Longhi radiator fits best
Bedrooms, nurseries and allergy-prone households that value silent, steady heat over fast warm-ups.
Who should skip the De’Longhi radiator
If you want a room warm within minutes, a ceramic heater like the DREO Atom One reacts much faster.

8. BLACK+DECKER BHDC201 Personal Ceramic Heater
Best Personal Heater for Under the Desk
- Low price and very light at 2.8 lb
- Low (750W), high (1500W) and fan-only settings
- Adjustable thermostat dial
- Tip-over and overheat shut-off
- Manual controls only
- 1-year limited warranty
- Type: ceramic, 1500W / 750W
- Modes: low, high, fan only
- Thermostat: adjustable manual dial
- Safety: tip-over and overheat shut-off, power indicator light
- Weight: 2.8 lb
- Warranty: 1-year limited
BLACK+DECKER’s BHDC201 is a small personal heater that has become a staple on Amazon for office and under-desk use. It has three settings: fan only, low at 750 watts and high at 1500 watts, plus a manual thermostat dial so it cycles rather than running flat out all day.
Automatic tip-over and overheat shut-off cover safety, and a power light shows at a glance that it is running. At 2.8 pounds with a carry handle, it is easy to move from the office to the bedroom. The 750W low setting is a nice touch for small spaces, because it uses half the power of most heaters while still keeping your legs warm.
Who the BLACK+DECKER BHDC201 fits best
Office workers and students who want a simple, low-cost heater for personal warmth at a desk.
Who should skip the BLACK+DECKER BHDC201
If you want a digital thermostat and remote, the DREO compact heater is a worthwhile upgrade.

Buying Guide: How to Shop for a Space Heater on Amazon
Check the Safety Certification
Look for ETL, UL or CSA listing in the product details or images. A certification mark means the heater was tested by an independent lab. Be wary of listings that only say “safe” or “certified” without naming the lab.
Read Reviews the Smart Way
- Prefer heaters with a long review history over brand-new listings with a handful of perfect ratings.
- Read the 3-star and 2-star reviews; they often reveal real problems like noise, odors or early failures.
- Look for reviews written after a full winter of use, not just the first week.
- Check that reviews match the exact model, since some listings merge several products.
Know Who Sells and Ships It
Heaters sold or fulfilled by Amazon usually come with easier returns. If a listing is sold by a third-party seller, check the seller rating and return policy before you buy, and register the heater with the manufacturer to activate the full warranty.
Match the Heater to Your Room
| Room | Best type | Pick from this list |
|---|---|---|
| Desk or under-desk | Small ceramic, 750–1500W | BLACK+DECKER BHDC201, DREO compact heater |
| Bedroom | Quiet ceramic tower or oil-filled radiator | DREO 24-inch tower, De’Longhi radiator |
| Living room | Oscillating ceramic with thermostat | DREO Atom One, Lasko 751320 |
| Large room or basement | Infrared + PTC | Dr. Infrared DR-968 |
Watch the Wattage and Your Circuit
Almost every plug-in heater draws up to 1,500 watts, about 12.5 amps. Plug it directly into a wall outlet, never into a power strip or thin extension cord, and avoid running it on the same circuit as a microwave or hair dryer.
Consider Running Costs
A 1,500W heater on high uses 1.5 kWh per hour. At 17 cents per kWh, that is about 26 cents per hour. Models with ECO modes, real thermostats and low settings cost less over a winter because they do not run at full power all the time.
Frequently Asked Questions
What is the best-selling space heater on Amazon?
The DREO Atom One, Lasko 751320 tower and Amazon Basics ceramic heater are among the best-selling and most-reviewed space heaters on Amazon. Rankings change daily, so check the current Best Sellers list before you buy.
Are low-cost space heaters on Amazon safe?
Price alone does not decide safety. A low-cost heater with ETL or UL certification, tip-over protection and overheat protection can be safe. Avoid listings with no named safety certification or with many reports of melting plugs or burning smells.
Is it better to buy a space heater on Amazon or in a store?
Amazon usually has more models, more owner reviews and easy returns, which makes it a good place to compare. Buying in a store lets you see the size and hear the noise in person. Either way, check the certification and warranty.
How do I know if a space heater review is reliable?
Look for detailed reviews that mention room size, noise, use over several weeks and any problems. Reviews from verified purchases that describe both pros and cons are usually more useful than short five-star comments.
Final Verdict: The Best Space Heater on Amazon in 2026
The DREO Atom One is the best all-round space heater you can buy on Amazon right now: it is proven, precise and quiet. If you are watching every dollar, the Amazon Basics 1500W ceramic heater covers the essentials, and for big rooms the Dr. Infrared DR-968 remains the best-selling infrared heater for good reason.
