Here's what most space heater listings won't tell you: nearly every plug-in model on Amazon draws the same 1,500 watts from a standard outlet. A 1,500-watt heater turns that electricity into about 5,100 BTUs of heat per hour, whether it is a budget model or a premium one. Claims about "60% more heat" or "200% farther reach" describe how the heat is moved around the room, not how much is made.
So the useful questions are different. How does the heat reach you: a fan blowing warm air, a radiator that warms the room slowly and silently, or infrared that warms what it faces? How loud is it at 2 a.m.? Does the thermostat hold a steady temperature, and what happens if a dog knocks it over? Those answers decide whether a heater works for a bedroom, a home office, or a drafty living room.
We compared current Amazon US listings and owner-feedback patterns for six space heaters on October 3, 2026, covering four heater types. We didn't test them hands-on, and prices, availability, and listing details can change. Whichever you choose, read the safety section below before the first cold night.
Our Top Pick
The DREO HSH006 is the best space heater for most rooms up to a typical bedroom or home office. It's small, quiet, holds a temperature in 1-degree steps, and shuts off if it tips over. Choose a different type for silent all-night radiant heat or for a large open room.

The six best space heaters
DREO HSH006 Space Heater with Thermostat and Remote
The DREO HSH006 is the most popular indoor space heater on Amazon for good reasons. It's a 10-inch, 3-pound ceramic heater that fits on a floor, a desk, or a nightstand, and its listing covers the details that make daily use easier: a thermostat from 41 to 95°F in 1-degree steps, Power, ECO, and Fan Only modes, a remote, a 12-hour timer, and a claimed 34 dB noise level from a brushless fan motor.
Safety features are thorough for a heater this small. The listing specifies a tilt sensor for tip-over shut-off, overheat protection, flame-retardant V0 housing, and a child lock. DREO rates it for about 200 square feet, which matches a typical bedroom or home office.
Owner feedback is strong on what matters most: it heats quickly, holds a steady temperature, stays quiet, and the remote gets used far more than people expect. The recurring complaint is reliability. A noticeable share of owners report units that stopped working after several months, so keep the receipt and register the warranty.
Skip this if you need to heat a large open room or want silent, fan-free heat.
Pros
- Precise thermostat in 1-degree steps
- Quiet enough for a bedroom or video calls
- Tip-over, overheat, and child-lock protection
- Small enough for a desk or nightstand
Cons
- Sized for one room, not open-plan spaces
- Recurring reports of units failing after months
Lasko 751320 Ceramic Tower Space Heater with Remote
The Lasko 751320 is the classic ceramic tower: 22.5 inches tall, 1,500 watts, with wide oscillation that sweeps warm air across a room instead of heating one spot. It has two heat settings, an adjustable thermostat, a remote, and a 7-hour auto-off timer. The listing highlights ETL certification, a self-regulating ceramic element, overheat protection, and a cool-touch housing. Lasko lists a 3-year limited warranty.
It's one of the most reviewed heaters on Amazon, and owner feedback is consistent: it warms a living room or medium bedroom quickly, stays reasonably quiet, and the remote and timer are genuinely useful. The trade-offs show up repeatedly too. The thermostat moves in 5-degree increments, so fine-tuning the room is harder than with the DREO, and a share of owners report reliability problems.
The tower shape is the reason to buy it. Heat leaves at a height closer to where you sit, and oscillation spreads it across a couch or a bed.
Skip this if you want precise temperature control or a heater for a desk.
Pros
- Oscillation spreads heat across a medium room
- Remote with a 7-hour timer
- ETL listed with cool-touch housing
- 3-year limited warranty
Cons
- Thermostat adjusts in 5-degree steps
- Some reliability complaints
De'Longhi EW7707CM Oil-Filled Radiator Heater
The De'Longhi EW7707CM is an oil-filled radiator, the most different heater on this list. There's no fan. Electricity warms a sealed reservoir of oil inside steel fins, and the fins warm the room through radiant and convective heat. The result is near-silent operation, no blowing dust, and heat that keeps radiating for a while after the element cycles off.
The listing specifies 1,500 watts with three settings, an adjustable thermostat with a ComfortTemp mode, an anti-freeze mode that switches on below 41°F, a thermal cut-off, built-in wheels, and a 3-year warranty. It weighs 23.2 pounds, and De'Longhi says the sealed oil never needs refilling.
Owners repeatedly call it dead quiet and well suited to small rooms. The mixed feedback is what you'd expect from a radiator: it takes longer to warm a room than a fan heater, some owners expected more heat output, and a few mention an odor during the first runs. Turn it on before bedtime rather than when you're already cold.
Skip this if you want instant heat or need to carry the heater between rooms often.
Pros
- No fan, so near-silent for sleeping
- Gentle heat without blowing dust around
- Anti-freeze mode and thermal cut-off
- Wheels and a 3-year warranty
Cons
- Slow to warm a cold room
- Heavy at 23.2 pounds
- Some owners report an odor during first use
Dr Infrared Heater DR-968 Portable Space Heater
The Dr Infrared DR-968 is a 19-pound wood-finish cabinet heater for spaces where a small ceramic heater runs constantly and never catches up. It combines infrared quartz tubes with a ceramic PTC element and a blower the listing rates at 39 dB. It adds an electronic thermostat from 50 to 85°F, a 12-hour timer, a remote, casters, tip-over and overheat protection, and a lifetime filter.
Treat the large-room claims with care. Like every heater here, it draws 1,500 watts and produces about 5,100 BTUs per hour, so it can't create more heat than the compact models. What it does differently is distribution: a large blower, a heavy cabinet, and steady output that owners say works well in basements, open living areas, and drafty rooms.
Owner feedback praises heat output, quiet operation, and the furniture-style look. Reliability is the main negative: most owners report years of use, but some describe failures after around three years.
Skip this if you're heating one small room. A compact heater does the same job for less money and floor space.
Pros
- Built for larger rooms and basements
- Quiet blower with an electronic thermostat
- Casters make a heavy unit movable
- Furniture-style cabinet
Cons
- Same 1,500-watt output as smaller heaters despite the claims
- Heavy and bulky
- Some reports of failure after a few years
DREO Smart Wall Heater DR-HSH009S
The DREO Smart Wall Heater solves a problem portable heaters create: floor space and the risk of something getting knocked over or covered. It mounts on the wall, oscillates 120 degrees, and its listing specifies a thermostat from 41 to 95°F in 1-degree steps, schedules in the DREO app, Alexa and Google Home voice control, and a display that dims automatically in a dark bedroom. The box includes mounting accessories and a drilling guide.
Owners find installation easy, around 15 minutes for several of them, and like how quietly it runs and how well it blends into a room. The smart controls let you warm a room before you wake up or get home. The weak spot is durability: multiple owners report units that stopped working after weeks or months.
A wall heater makes the most sense in a small bedroom, a kid's room, a home office with little floor space, or anywhere a pet would sniff around a floor unit. If you're building out the rest of a connected home, see our best smart home devices guide.
Skip this if you rent and can't drill, or need to move the heater between rooms.
Pros
- Off the floor, out of reach of pets and kids
- App schedules and voice control
- Precise thermostat and auto-dimming display
- Straightforward installation
Cons
- Requires drilling into the wall
- Not portable
- Durability complaints
Amazon Basics Ceramic Space Heater with Tip-Over Protection
The Amazon Basics ceramic heater is the low-cost option that still includes the safety basics: tip-over and overheat protection, plus High (1,500 W), Low (900 W), and Fan Only settings. At 2.8 pounds and under 10 inches tall, it fits under a desk or in a small bedroom, and the listing rates it at 43 dB.
Owners say it warms small spaces quickly and is good value for the money. Amazon's own listing tells buyers to keep it out of bathrooms, laundry rooms, and other humid spaces, which is good advice for any portable heater. The trade-off is lifespan: reliability and durability complaints are more common here than for any other pick, with owners describing units that failed early or within a year. Noise feedback is also mixed.
Buy it for a small room you need to warm for one winter or for occasional use, and keep the packaging for returns. For a heater that runs every day, the DREO is the better long-term buy.
Skip this if you want a heater that will run daily for several winters.
Pros
- Lowest cost of the six
- Tip-over and overheat protection
- Low setting for smaller spaces
- Very compact
Cons
- Most frequent reliability and durability complaints
- Basic controls without a precise thermostat display
- Noise feedback is mixed
Space heater safety: the rules that matter more than features
Space heaters are a leading cause of home heating fires, and most of those fires come down to how the heater is used rather than which model it is. These basics apply to every heater on this list:
- Plug it directly into a wall outlet. A 1,500-watt heater draws about 12.5 amps. Extension cords and power strips can overheat at that load.
- Keep three feet of clear space around the heater: away from beds, curtains, sofas, clothing, and paper.
- Don't leave it running when you leave the room or go to sleep, unless it's designed for unattended overnight use and you're comfortable with that. A timer helps.
- Keep it on a hard, level floor, not on a rug or carpet that can block the air intake or tip it over.
- Keep it out of bathrooms and other wet areas unless the manufacturer specifically allows it.
- Look for tip-over and overheat protection and a safety certification mark such as UL, ETL, or CSA.
- Run one heater per circuit. Two 1,500-watt heaters on the same circuit can trip a breaker.
How to choose a space heater
Start with the room size. A typical 1,500-watt heater comfortably supplements heat in about 150 square feet, depending on insulation, ceiling height, and how cold it is outside. For larger spaces, a well-designed heater spreads heat better, but none of them heats a whole house.
Pick the heater type for how you'll use it. Ceramic fan heaters warm a space quickly and suit offices and bedrooms during the day. Oil-filled radiators are slower but silent and steady, so they work well overnight. Infrared heaters warm what they face, which helps in drafty rooms. Wall heaters free up the floor.
Insist on a real thermostat. A heater that cycles to hold a set temperature uses less energy than one that runs flat out. Fine steps of 1 degree are more comfortable than 5-degree jumps.
Check the noise. Fan heaters typically run around 35 to 45 dB. If you sleep with it on, a radiator or a heater with a quiet mode matters.
Watch running costs. At 1,500 watts, a heater uses 1.5 kWh per hour on high. Heating only the room you're in can save money compared with raising the whole-house thermostat, but running several heaters for many hours can cost more than central heat.
Winter air also gets dry and stale when windows stay shut. Our best air purifiers guide covers the other half of a comfortable room.
How we made these picks
We reviewed current Amazon.com listings and owner feedback for the US market, then compared heater type, safety features, thermostat range and precision, noise, size, warranty, and recurring positive and negative themes. We gave extra weight to reliability complaints, because a heater that fails mid-winter is worse than one with fewer features. Dynamic Amazon metrics informed the ranking but aren't reproduced here because they change; the Amazon buttons show the current listing.
This is research-based editorial analysis, not a hands-on lab test. Coverage area, noise, and BTU figures are manufacturer claims unless stated otherwise. Follow the safety instructions in the manual for the model you buy.
What is the best space heater for a bedroom?
For quiet, steady overnight heat, an oil-filled radiator such as the De'Longhi EW7707CM is the best fit because it has no fan. For faster heat and precise temperature control, the compact DREO HSH006 is the best choice.
Do more expensive space heaters produce more heat?
Not usually. Nearly all plug-in heaters are limited to about 1,500 watts by a standard household outlet, which produces about 5,100 BTUs per hour. Higher prices pay for better heat distribution, quieter operation, safety features, and build quality.
Is it safe to leave a space heater on overnight?
Fire-safety guidance is to turn heaters off when you leave the room or go to sleep. If you use one overnight, choose a model with tip-over and overheat protection, keep three feet of clearance, plug it directly into the wall, and use the timer.
Can I plug a space heater into an extension cord or power strip?
It's not recommended. A 1,500-watt heater draws about 12.5 amps, which can overheat many extension cords and power strips. Plug it directly into a wall outlet.
What size space heater do I need?
A typical 1,500-watt heater supplements heat in roughly 150 square feet. Larger rooms benefit from a heater that distributes heat well, like a tower or an infrared cabinet, but no plug-in heater replaces central heating for a whole home.
Are space heaters expensive to run?
A 1,500-watt heater uses 1.5 kWh per hour on high. Your cost depends on your electricity rate and how long it runs. A thermostat and lower settings reduce the cost because the heater cycles instead of running constantly.
