Best Electric Space Heaters for Winter 2026–2027

1. How We Chose These Heaters

Start with the honest part. We did not run our own heat-up tests for this guide, so you will not find invented numbers about how many degrees a heater raised a room in how many minutes. Every specification here comes from the manufacturer's spec sheet, owner's manual or product listing, and where those sources disagree or leave something out, we say so.

That is less limiting than it sounds, because the most important fact about electric space heaters is not something a test would reveal: every 1,500-watt resistance heater turns its electricity into the same amount of heat. So we judged heaters on the things that genuinely differ.

First, thermostat quality. An electronic thermostat that steps down to a low setting holds a room steady without running at full power longer than needed; a heater with no thermostat runs flat out until you switch it off. Second, documented safety: a tip-over switch, overheat protection and a listing mark from a recognized testing laboratory such as UL, Intertek (ETL) or CSA. Third, how the heat arrives, fan-forced or radiant, which decides whether a heater suits a bedroom or a drafty den. Finally, we chose one pick per heater type rather than seven versions of the same ceramic box, and favoured long warranties and available replacement parts.

2. The 5,118 BTU Truth About "Energy Efficient" Heaters

One watt of electricity converted to heat equals about 3.412 BTU per hour. A heater drawing 1,500 watts therefore produces about 5,118 BTU per hour, whether it is a ceramic cube, an oil-filled radiator, a mica panel or a wood-cabinet infrared heater. Resistance heating is effectively 100 percent efficient at the point of use: all the electricity becomes heat, because there is nowhere else for it to go. The fan motor and the display lights end up as heat in the room too.

So claims of "more heat" from a plug-in heater should make you suspicious. One manufacturer on our list advertises up to 60 percent more heat output, while its own manual rates the heater at 5,200 BTU, which is 5,118 rounded up. Another says its panel converts 100 percent of electricity into heat, which is true of the cheapest heater on the shelf too. The 1,500-watt cap is practical: at 120 volts it draws 12.5 amps, close to the limit of the 15-amp circuits most rooms are wired with.

So what does "energy efficient" mean on a heater box? Done honestly, it means a heater that wastes less of its output. A precise thermostat and a low setting stop it overheating a room you only needed warm. Timers and occupancy sensing stop it heating an empty room. Good air circulation or radiant delivery lets you feel comfortable at a lower setpoint. Those features can save real money. The heating element itself cannot.

3. The 7 Best Electric Space Heaters for 2026–2027

One pick per heater type, from a fan-forced ceramic circulator to a hardwired wall unit. Specifications come from each manufacturer's spec sheet, owner's manual or product listing, and where a source leaves something out, such as a listing mark or a tip-over switch, the card says so. Prices move constantly, so check the current one at the link.

Best OverallVornado AVH2 Advanced Whole Room Heater

Ceramic Fan-Forced Circulator, 1,500/750W

Best Overall

The AVH2 is the heater we would put in most bedrooms, home offices and living-room corners, and the reason is control rather than output. Like every plug-in heater on this list it tops out at 1,500 watts, but Vornado's Auto Climate control is an electronic thermostat that steps between the 1,500-watt high and 750-watt low settings to hold the temperature you set, instead of cycling the full 1,500 watts on and off. Vornado's vortex fan is designed to throw the warm air across the room rather than leave it pooled in front of the grille, and how evenly a room warms decides how comfortable you are at a given setting far more than any efficiency claim does. The owner's guide lists a tip-over switch and a multilevel overheat shut-off, the case is rated cool-touch, the grille spirals are tight enough to keep small fingers out, and a timer runs up to 12 hours. At 4.48 pounds it is easy to carry from the office to the bedroom at night, and Vornado backs it with a five-year warranty, the longest of the portables here. The trade-offs are a fan you will hear, no remote, and a spec sheet that does not name its safety listing, so check the rating label for a UL, ETL or CSA mark before you keep it.

Pros

• Auto Climate electronic thermostat steps between 1,500 W and 750 W to hold a set temperature
• Tip-over switch and multilevel overheat shut-off, per Vornado's owner's guide
• Cool-touch case and tight grille spirals around the fan
• Timer up to 12 hours, plus continuous or auto fan modes
• Five-year warranty and a 4.48 lb weight that makes it easy to move between rooms

Cons

• Fan-forced, so it is never silent; light sleepers may prefer a radiator
• No remote, and the listing mark is not stated on the spec sheet, so check the label

The Bottom Line

For most rooms, the Vornado AVH2 is the electric space heater to buy: every 1,500-watt heater makes the same heat, so what you are paying for is a real electronic thermostat, a tip-over switch and a five-year warranty, and the AVH2 has all three.

Best Smart HeaterLasko AR122 22-Inch Smart Ceramic Tower Heater

Smart Ceramic Tower, 750/1,300/1,500W

Best Smart Heater

If the heater in your house routinely runs in an empty room, this is the one that can genuinely cut the bill, because the cheapest heat is the heat you never make. Lasko's ClimaSense feature is built to detect whether the room is occupied, hold your set temperature while it is, and switch the heater off on its own when the room empties. Around that sits a full smart-home kit: control and scheduling in the Aria for Home app, voice control through Alexa or Google Assistant, front touch controls, a 12-hour timer and a Night Mode that dims the display. Output steps through three settings, 750, 1,300 and 1,500 watts, which gives the thermostat a useful middle ground. Lasko lists 360-degree topple sensing with lift and tip-over sensors, automatic overheat protection, a cool-touch housing and ETL listing, and the tower weighs 4.0 pounds. It oscillates to spread warm air across a living room. The caveat is the usual one for connected appliances: the smart features depend on the app and your Wi-Fi, and an app is only as good as the company's willingness to keep supporting it. Lasko's warranty is three years.

Pros

• ClimaSense occupancy detection can turn the heater off when the room is empty
• Three output levels: 750, 1,300 and 1,500 watts
• App scheduling plus Alexa and Google Assistant voice control
• Topple, lift and tip-over sensing, overheat protection and ETL listing, per Lasko
• 12-hour timer and Night Mode; three-year warranty

Cons

• The features that save money depend on the app and Wi-Fi
• A fan heater, so expect some noise on high

The Bottom Line

Pick the Lasko AR122 if heaters in your home get left on: occupancy sensing and app schedules are the features that actually cut running hours.

Best Oil-Filled RadiatorDe'Longhi Dragon Digital TRD40615E Oil-Filled Radiator

Oil-Filled Radiator, 700 to 1,500W

Best Oil-Filled Radiator

An oil-filled radiator does not make heat more cheaply than a ceramic heater; the oil is a heat store, not a fuel. What it does is change how the heat arrives. The Dragon's sealed oil reservoir and six fins warm up slowly, then give off steady radiant and convected heat with no fan at all, and they keep radiating after the elements cycle off, which evens out the temperature swings a thermostat creates. That makes it the quiet choice for bedrooms and nurseries. This digital version has an LED control panel, three power settings between a 700-watt minimum and 1,500-watt maximum, an ECO function De'Longhi says regulates power and temperature, a 24-hour timer, anti-freeze protection, a child lock, a thermal cut-off and a safety thermostat. It rolls on pre-assembled SmartSnap castors, which you will appreciate, because De'Longhi lists it at 25.61 pounds. Two honest notes from De'Longhi's own US listing: it says the heater is only suitable for well-insulated spaces or occasional use, and its spec table does not spell out a tip-over switch, so confirm that on the box if it matters to you. The listing shows a two-year warranty.

Pros

• No fan: silent operation suited to bedrooms
• Digital thermostat, three power settings from 700 to 1,500 watts, and an ECO mode
• 24-hour timer, child lock, anti-freeze setting and thermal cut-off
• Keeps radiating after it cycles off, which smooths temperature swings
• Pre-assembled castors and a sealed reservoir that never needs refilling

Cons

• Slow to warm a cold room compared with a fan heater
• Heavy at 25.61 lb, and the US spec table does not list a tip-over switch

The Bottom Line

The De'Longhi Dragon is the quiet bedroom pick: no fan, steady radiant warmth and a real digital thermostat, at the cost of a slow warm-up and a lot of steel.

Best Panel HeaterDe'Longhi HMP1500 Mica Thermic Panel Heater

Micathermic Panel, 750/1,500W

Best Panel Heater

A micathermic panel sits between an oil radiator and a fan heater. Its heating element is sheathed in thin sheets of mica, so there is no reservoir of oil to warm first and the panel starts radiating sooner, while still heating mainly by radiation and convection. One caution about De'Longhi's own listing: it says in one place there is no fan and in another that the unit has a dual lateral fan system for heat distribution, so expect quiet rather than guaranteed silence. The HMP1500 is a slim panel with two settings, 1,500 and 750 watts, an adjustable thermostat on a dial, an internal tip-over switch, a thermal shut-off and a standby setting De'Longhi says helps prevent frozen pipes. It ships with roll-around castors and a wall bracket, so you can hang it on a wall and get it off the floor entirely, which is a real advantage in a room with pets or toddlers. De'Longhi's marketing says mica heaters convert 100 percent of electricity into heat, which is true and also true of every other resistance heater on this page. The dial thermostat is less precise than the electronic controls on our top picks, and some colour versions show as out of stock on De'Longhi's US site, so check the exact model number when you buy. The listing shows a two-year warranty.

Pros

• Slim panel that heats mostly by radiation and convection, so it is quiet
• Two settings, 1,500 and 750 watts, with an adjustable thermostat
• Internal tip-over switch, thermal shut-off and anti-freeze standby setting
• Includes castors and a wall bracket for floor or wall mounting
• Light enough to move easily, unlike an oil-filled radiator

Cons

• Dial thermostat is less precise than an electronic one
• Some versions show out of stock on De'Longhi's US site; match the model number

The Bottom Line

Choose the HMP1500 when you want radiator-style quiet without radiator weight, or a heater you can hang on the wall out of reach.

Best Infrared HeaterDr. Infrared Heater DR-968 Portable Space Heater

Infrared Quartz and PTC Cabinet, 1,000/1,500W

Best Infrared Heater

The DR-968 pairs infrared quartz tubes with a PTC element and a blower inside a wood-look cabinet. The manual lists 1,500 watts on high, 1,000 on low, and an ECO mode that switches between the two to reach and hold the set temperature, with an electronic thermostat Dr. Heater lists at 50 to 85 degrees. It comes with a remote, an LED display, a 1-to-12-hour timer and a Night Mode that, once the room reaches the set temperature, samples it only every 30 minutes instead of every 4, for quieter nights. Safety is well covered: the manual describes a tip-over switch, an overheat cut-off, a separate inlet-air overheat cut-off if the intake is blocked, and a cool-touch cabinet, and Dr. Heater says the unit is UL certified. Ignore the marketing line that it produces up to 60 percent more heat. The same manual rates it at 5,200 BTU, which is simply the 5,118 BTU per hour every 1,500-watt heater produces, rounded up. What earns it a place is longevity: Dr. Heater sells replacement heating elements, blower motors, thermal fuses and control boards for this model, which is rare in a category where most heaters are thrown away when one part fails. The washable rear filter needs cleaning about monthly, and the manual lists 23.5 pounds. It carries a three-year limited warranty.

Pros

• Electronic thermostat, ECO mode and a remote control
• Tip-over switch, overheat cut-off and inlet-air overheat protection, per the manual
• UL certified, per Dr. Heater
• Replacement elements, blower motor and control board sold for this model
• Night Mode reduces how often the blower cycles; three-year warranty

Cons

• "Up to 60% more heat" marketing is not physically possible at 1,500 watts
• Bulky cabinet at 23.5 lb, and the filter needs regular cleaning

The Bottom Line

Buy the DR-968 for its thermostat, remote and replaceable parts, not for its "more heat" claim; it makes the same heat as every other 1,500-watt heater.

Best Wall HeaterCadet Com-Pak CSC151TW 1500W Wall Heater

Hardwired Fan-Forced Wall Heater, 1,500W 120V

Best Wall Heater

For a room that is cold every single winter, such as a bedroom over the garage or a finished basement room the ducts never reached, a hardwired wall heater beats any portable. There is no cord to trip on, nothing to tip over, nothing for a curtain to fall onto and no outlet doing a job it was never built for. The CSC151TW is Cadet's complete Com-Pak unit: a recessed heater assembly with a built-in thermostat, galvanized wall can and grille, rated by Cadet at 1,500 watts, 120 volts, 12.5 amps and 5,120 BTU. It recesses into a rough opening of 8 by 10-1/8 by 4 inches, Cadet recommends mounting it about 12 inches off the floor, and it includes a high-temperature safety shutoff. Because it is a fixed heater on its own circuit, it needs wiring: Cadet's manual limits the load on a breaker to 80 percent of its rating, and 12.5 amps is more than 80 percent of a 15-amp breaker, so plan on a 20-amp circuit and a licensed electrician if you are not comfortable in the panel. Cadet also makes 240-volt versions that draw half the amperage for the same heat. The warranty is two years.

Pros

• Built-in thermostat, wall can and grille in one complete unit
• Hardwired: no cord, no outlet strain and nothing to tip over
• High-temperature safety shutoff
• Recesses into an 8 x 10-1/8 x 4 inch rough opening
• 240-volt versions available for a lower-amperage circuit

Cons

• Requires a dedicated circuit and wiring, so budget for an electrician
• Fixed in place; it heats one room, permanently

The Bottom Line

The Cadet Com-Pak is the right answer for a room that is always cold: a permanent, thermostat-controlled heater with no cord to misuse.

Best for a DeskLasko CD09475 9-Inch Oscillating Ceramic Space Heater

Personal Ceramic Heater, 900/1,500W

Best for a Desk

Sometimes the efficient move is to heat the person rather than the room, and a small heater under a desk does that well. The CD09475 is a 3.1-pound, 9-inch ceramic heater with high and low settings that Lasko's spec sheet puts at 1,500 and 900 watts, base oscillation to spread the warmth across your legs, a tip-over switch, what Lasko calls 2X overheat protection, a cool-touch housing, ETL listing, a removable easy-clean filter and a 6-foot cord. Here is the honest catch, and the reason it is not ranked higher: it has no thermostat. The manual shows a heat button that toggles high and low and a timer you can set for 1, 2 or 4 hours; without the timer it shuts itself off after 8 hours. That means it draws its full wattage the whole time it runs, so used as a room heater it can cost more than a thermostat-controlled model that throttles back. Used as intended, for a couple of hours at a desk with the house thermostat turned down, it is a sensible, cheap way to stay warm. Lasko's warranty is three years.

Pros

• Small and light at 3.1 lb, with oscillation for under-desk use
• Tip-over switch, overheat protection, cool-touch housing and ETL listing
• 1, 2 or 4-hour timer, plus an automatic 8-hour shutoff
• Removable easy-clean filter; three-year warranty

Cons

• No thermostat: it runs at full wattage until the timer or you switch it off
• Sized for personal warmth, not for heating a whole room

The Bottom Line

Use the Lasko CD09475 to warm yourself at a desk for a few hours, not to heat a room; with no thermostat it never throttles back.

4. Ceramic, Oil-Filled, Mica, Infrared or Wall: Which Type Fits

Since every type makes the same heat per watt, the choice comes down to how quickly the heat arrives, how it feels, how much noise you will tolerate and where the heater has to live.

Ceramic fan heaters

A ceramic heater blows air across a self-regulating ceramic element. It warms you within a minute or two, it is light and cheap, and a good one, like the Vornado AVH2, circulates the warm air instead of blasting a hot spot. The costs are fan noise and dust; Vornado's manual recommends cleaning the outside weekly.

Oil-filled radiators

An oil-filled radiator heats a sealed reservoir of oil, which warms the fins and the room by radiation and convection. It is silent and keeps giving off heat after it cycles off, but it is slow to take the chill off a cold room and it is heavy. It suits a bedroom you warm before you need it.

Micathermic panels

A mica panel uses an element sheathed in thin mica sheets. With no oil to warm, it responds faster than a radiator but stays quiet, slim and often wall-mountable.

Infrared, quartz and wall heaters

Infrared heaters warm the people and objects they face rather than the air first, which is why they feel effective in drafty rooms. Cabinet models like the Dr. Infrared DR-968 add a blower, so they behave much like a quiet fan heater with a radiant component. A hardwired fan-forced wall heater, like the Cadet Com-Pak, is permanent heat for a room that needs it every winter: no cord, nothing to tip, but it needs its own circuit.

5. How to Size a Space Heater to the Room

The rule of thumb heater retailers publish, Sylvane's buying guide among them, is about 10 watts of heat per square foot of floor when the heater is the main heat source in a room with ordinary 8-foot ceilings and average insulation. By that rule a 1,500-watt heater covers about 150 square feet as primary heat, a 12-by-12 bedroom with a little to spare. As supplemental heat, topping up a room the furnace already warms, it will stretch further.

Adjust for the room you actually have. Older rooms with single-pane windows, little insulation or an outside wall on two sides need more, and installers commonly use 12 to 15 watts per square foot for drafty spaces. Ceilings higher than 8 feet need more too, because there is more air to warm. A tight, modern room can get by with less. Ignore any BTU figure printed beside a watt rule unless it uses the right conversion; a watt is about 3.4 BTU per hour, not 5.

Be wary of boxes that promise one plug-in heater will warm 500 or 1,000 square feet. At 5,118 BTU per hour that is only possible as a gentle top-up in a space that is already mostly warm. If the room is too big for one 1,500-watt heater, there is no "more powerful" plug-in to buy; the answer is two heaters on two different circuits, a hardwired 240-volt heater, or a proper fix such as a mini split. And if your heater runs on high for hours without reaching its set temperature, the room is losing heat faster than 5,118 BTU per hour, and no mode setting will change that.

6. What a Space Heater Costs to Run in Winter 2026–2027

The formula fits on a sticky note: watts divided by 1,000, times your electricity price per kilowatt-hour, equals the cost per hour. The US Energy Information Administration's most recent monthly figure, for July 2026 in its Electric Power Monthly, puts the average US residential price at 18.31 cents per kWh, up from 17.45 cents a year earlier. Your own rate could be well above or below that, so check the per-kWh price on your bill and substitute it.

At 18.31 cents, a heater running flat out at 1,500 watts costs about 27 cents an hour. That is the most it can cost, and it is the same for every 1,500-watt model. The table below shows the ceiling for each common setting on the heaters in this guide.

Those are worst-case figures. A heater with a thermostat throttles back or cycles once the room is warm, and how much of the time it runs depends on the weather, the room and your setpoint; if it runs half the time, halve the numbers. A heater with no thermostat, like our desk pick, really does draw full wattage the whole time it is on. To find your real cost, put a plug-in electricity usage meter between the plug and the wall for a week and multiply the kilowatt-hours by your rate.

7. Safety: The Features and Habits That Actually Matter

Space heaters are one of the few appliances in a house that can start a fire while working exactly as designed. The Consumer Product Safety Commission estimates that portable heaters, including electric space heaters, were involved in an average of 1,600 fires a year from 2020 to 2022, causing an average of 70 deaths and 150 injuries annually. The National Fire Protection Association counts an estimated average of 38,881 home heating equipment fires a year from 2019 to 2023, with 432 civilian deaths, and space heaters and heating stoves were the equipment involved in 29 percent of them.

Three features should be non-negotiable. A listing mark from a nationally recognized testing laboratory, such as UL, Intertek's ETL or CSA, means the design was tested against a safety standard; Massachusetts' Department of Fire Services, among others, tells buyers to look for one. A tip-over switch cuts power if the heater falls. Overheat protection shuts it down if the intake is blocked or it runs too hot. Be particularly careful with no-name heaters from online marketplaces, where a listing mark printed in a photo is not the same as one on the rating label.

Habits matter as much as hardware. CPSC says to turn heaters off when sleeping, and the US Fire Administration says to turn them off when you leave the room or go to bed, so warm a bedroom before bed and let the timer finish the job. Keep pets and children out of the three-foot zone, never run the cord under a rug, and keep working smoke alarms on every level.

8. Outlets, Circuits and Why Extension Cords Are Out

CPSC's instruction is blunt: plug electric space heaters directly into a wall outlet, never into an extension cord or power strip. The heater manuals we read say the same; Lasko's adds surge protectors, multi-outlet adapters and cord reels to the banned list. The reason is current. A 1,500-watt heater draws 12.5 amps continuously for hours, and a light-duty extension cord or a cheap power strip was never designed for that load, so it heats up at its connections, which is exactly where fires start.

The wall outlet can be the weak link too. An old receptacle with worn contacts grips the plug loosely, the connection heats, and the plug or faceplate gets hot. Dr. Heater's manual tells owners to check the plug and outlet often while the heater runs and to have the outlet replaced if either gets hot. A plug that feels warm is normal; one too hot to hold is not.

Then there is the circuit. A typical bedroom circuit is 15 amps and also feeds lamps, a TV and chargers. If the breaker trips, Vornado's manual suggests running only one heater at once, unplugging other electrical products while it runs, or having an electrician add a circuit. Two heaters in one room belong on two different circuits. A hardwired heater like the Cadet Com-Pak sidesteps all of this on its own circuit; Cadet's manual caps a breaker's load at 80 percent of its rating, so a 1,500-watt, 120-volt unit belongs on a 20-amp circuit.

9. How to Use a Space Heater to Actually Save Money

A space heater only saves money when it lets you turn something else down. Run one in the living room while the furnace keeps the whole house at 70 degrees, and you have simply added up to 27 cents an hour to your bill. The saving comes from zone heating: keeping the room you are in comfortable while the central thermostat sits lower for the rest of the house. The Department of Energy says turning a thermostat back 7 to 10 degrees for 8 hours a day can save up to 10 percent a year on heating and cooling, and a space heater is what makes that setback livable in the one room you occupy.

Close the door so the warmth stays with you, set the heater to the lowest temperature you are comfortable at, and use the timer. With a smart model like the Lasko AR122, let occupancy sensing switch it off when you walk out.

Move the warm air, too. Heat rises and pools at the ceiling, so in winter run a ceiling fan on low in the reverse, clockwise direction to push it gently back down without creating a chilly breeze; our guide to ceiling fan direction in summer and winter explains the switch.

Watch the humidity rather than the marketing. Heating air lowers its relative humidity because warm air can hold more moisture, so any heater can make a room feel drier, even the radiators sold as not drying the air. If the room feels dry, that is a humidifier question; if you are fighting condensation on cold windows instead, read whether you need a dehumidifier in winter.

10. When a Space Heater Is the Wrong Answer

If you are heating the same room every evening all winter, look at the bill honestly. A heat pump moves heat from outside rather than making it from resistance, and the Department of Energy's Energy Saver guidance puts the reduction in electricity used for heating at roughly half or more compared with electric resistance heat, including plug-in space heaters. If your home already heats with a heat pump, a resistance space heater produces heat less efficiently than the system it supplements, so it only pays in a single room with the rest of the house set well back. For a cold addition or a converted garage, a ductless unit is usually the better long-term buy; see our best mini split heat pumps.

A garage or workshop is another poor fit. At 5,118 BTU per hour, a plug-in heater barely warms your hands at a bench in a two-car garage, and space heater manuals warn against using them where gasoline, paint or other flammable liquids are stored. A properly sized 240-volt or vented gas unit is the right tool, covered in our guide to the best garage heaters.

Power outages are the third trap. A space heater is one of the hungriest things you can plug into a battery: at 1,500 watts, a 1,000 watt-hour power station would be empty in about 40 minutes even before inverter losses. Our explainer on whether a portable power station can run a space heater runs the numbers and covers better ways to stay warm.

And never bring a fuel-burning heater made for outdoor or garage use into a living space. Unvented combustion heaters can produce carbon monoxide; an electric heater does not.
