Best Space Heater
The best space heater is a plug-in electric one with a thermostat, a tip-over shutoff and a rating that covers your room. For a large room, get the Lasko DUO Comfort Tower or, if you don't need a timer, the Vornado Vortex whole room heater. For a small room, get the Lasko High Velocity Hybrid. For a bedroom, get the Honeywell slim ceramic tower heater and use it to warm the room before you get in bed. Plug any of them straight into a wall outlet, and never run one while you sleep.
Best Space Heater for Large Room
The best space heater for a large room with a thermostat covers your floor area, holds the temperature you set and shuts off if it tips over. Find your room below and pick the heater at the end of that line.
- The room is a big living space and you want a thermostat and an 8-hour timer: the Lasko DUO Comfort Tower.
- The room is a big living space and you don't need a timer: the Vornado Vortex whole room heater.
- The room is a spare room or small office of 150 square feet or less: the Lasko High Velocity Hybrid.
- The room runs 150 to 200 square feet and you want it to draw less power on a low setting: the Dreo Solaris Slim.
- You sit in one spot, at a desk or in a chair, and want the warmth on you instead of the room: the Dr. Heater infrared heater.
- You want the bedroom warm before you get in bed: the Honeywell slim ceramic tower heater.
- You want a heater running while you sleep, or alone in a room with a baby: no space heater should do that. Warm the room while you're in it, then switch the heater off.
The Lasko DUO Comfort Tower is [ETL Listed and rated for 300 square feet]( https://lasko.com/products/lasko-duo-comfort-high-velocity-dc-motor-tower-fan-and-space-heater-with-remote-control-black), with an adjustable thermostat, an 8-hour timer and 900 to 1500 W settings. If your room is bigger than that, put the heater where you sit instead of expecting it to warm the whole floor. The Vornado Vortex has two heat settings, a fan-only mode and Auto Climate Control. If you want a timer, get the Lasko instead.
The Dreo Solaris Slim [heats up to 200 square feet]( https://www.mantripping.com/stuff/dreo-slim-h3-space-heater-review.html). The Dr. Heater has 1000 W and 1500 W settings and uses an infrared quartz tube plus a PTC element.
Every heater here plugs [straight into a wall outlet, never into an extension cord or power strip]( https://www.cpsc.gov/Newsroom/News-Releases/2023/CPSC-Warns-Consumers-to-be-Cautious-When-Using-Space-Heaters-Furnaces-and-Fireplaces-This-Winter). Keep every other appliance off that outlet too. Keep the heater 3 feet from drapes, furniture and bedding, keep children and pets supervised around it, and keep it out of the bathroom. If you're between two sizes, take the bigger one.
Best Space Heater for Small Room
The best space heater for a small room is the Lasko High Velocity Hybrid when the room is 150 square feet or less. It has three heat settings from 900 W to 1500 W, an adjustable thermostat with Auto Eco, an 8-hour timer, a tip-over safety switch and automatic overheat protection. It's [ETL Listed with a 150 square foot maximum]( https://lasko.com/products/lasko-all-season-high-velocity-hybrid-tower-fan-and-space-heater-in-one-with-remote-control-fhv820-white) and carries a 3-year warranty.
That makes it the best space heater for a small room with a thermostat: set a temperature and it cycles to hold it, so you never switch it on and off by hand. If the room runs past 150 square feet, get the Dreo Solaris Slim instead.
The kind of heater that's best for a small room is a 1500 W model with a lower setting, not a small low-watt unit, because low-watt models are generally hit or miss. Keep it electric too. Fuel-burning heaters cause carbon monoxide poisoning, an odorless, colorless, poisonous gas.
Best Space Heater for Bedroom
The best space heater for a bedroom with a thermostat is the Honeywell slim ceramic tower heater, used to warm the room before you get in bed and not to run while you sleep.
Its thermostat mode cycles to the temperature you set, and the timer runs 1, 2, 4 or 8 hours. Set the timer for a stretch that ends before bedtime, then switch the heater off. It also has a remote, a 360° tip-over switch and a Safeguard motion sensor that turns it off if an object gets too close, which suits a room with a bed, a nightstand and a laundry pile. It measures 8.74 by 6.69 by 23.15 inches and carries a 3-year warranty. Among electric space heaters for a bedroom, that combination is the one to buy.
Sleep is where heater fires turn deadly. Heating fires between midnight and 8 a.m. were 19% of the total but [48% of civilian deaths]( https://www.bismarcklibrary.org/DocumentCenter/View/34442/Heating-Fire-Facts-NFPA-Dec-2018) in 2012 to 2016.
Are room heaters safe for babies? Only when you're in the room with them.
Do not operate unattended in confined spaces with infants or with people with reduced physical, sensory or mental capabilities. The release notes an overheating hazard to children, elderly people and people with disabilities.
The best space heater for a nursery is the same Honeywell, under the same attended-use rule. Keep young children supervised in the same room, and keep clothing away from the heater's hot surface.
What Is the Warmest Type of Space Heater
The warmest type of space heater is the one that sends its heat to where you are. A radiant heater [will warm objects or people in its path]( https://dnr.mo.gov/document-search/space-heaters-pub2849/pub2849) instantly, and it heats a room slowly. A convection heater with a fan heats an area quickly and spreads the heat around. A ceramic heater [heats up faster]( https://newair.com/blogs/learn/ceramic-heaters-vs-oil-filled-heaters) than an oil-filled one, while an oil-filled radiator [disperses heat slowly and steadily into a room]( https://www.consumerreports.org/appliances/space-heaters/buying-guide) and keeps radiating after you switch it off.
If you sit in one spot, take the infrared heater from the list above. If you heat the whole room, take a fan-driven ceramic tower.
No type is the most efficient type of space heater at turning electricity into heat. All electric resistance heaters are 100% efficient at the point of use, so any difference comes from heat distribution and run time. NewAir's own blog claims oil-filled heaters can help lower energy use, and that claim is untested.
What Are the Best Space Heaters in 2026, According to Reviews?
Reviews put the Dreo Solaris Slim first overall and the Vornado Vortex whole room heater first for large rooms.
The Dreo Solaris Slim was named top pick and best overall in an [8-week test of 13 heaters]( https://www.bobvila.com/reviews/best-electric-heaters/). The Vornado Vortex was named top pick, and the large-room pick, in a [three-part test of safety, heating and thermostat precision]( https://www.yourbestdigs.com/reviews/best-space-heater/).
One large-room pick gets passed over. The De'Longhi HMP1500 raised a 180 square foot test room by [6°F in one hour]( https://reviewed.com/home-outdoors/best-right-now/the-best-space-heaters), but its maker says it is only suitable for well insulated spaces or occasional use. Skip it for a room you heat every day.
Is There a Space Heater That Doesn't Use a Lot of Electricity?
Yes, if you pick a heater with a thermostat and a low setting and run it only in the room you use. A 1500 W heater [consumes 1.5 kWh per hour at full output]( https://www.pickhvac.com/space-heater/how-much-electricity-does-a-space-heater-use/), and the Dreo Solaris Slim in ECO mode drops to 900 W, or 0.9 kWh per hour.
The thermostat does the rest. Standalone electric heaters [tend to be more energy efficient if they have thermostatic controls]( https://www.uswitch.com/gas-electricity/guides/energy-efficient-heaters/), because they switch off when they reach a set temperature. Look for a digital thermostat and an economy mode that steps between heat levels as the room reaches your setting.
Best Space Heater Electric
The best electric space heater for a large room is the Lasko DUO Comfort Tower, or the Vornado Vortex whole room heater if you don't need a timer. They are the best indoor electric heaters for large rooms because both shut off if they tip over or overheat.
Tip-over protection is the feature to confirm on any electric heater you add to your list. UL's 2009 Q&A says a listed heater [must pass a tip-over test]( https://japan.ul.com/wp-content/uploads/2014/04/ul_ElectricHeaterTipoverProtection.pdf) and may do so with temperature limiting controls or a switch.
Electric means plug-in. Fuel-burning heaters are a separate category, and [portable kerosene and propane heaters are illegal for home use in Massachusetts]( https://www.mass.gov/doc/space-heater-safety-in-english/download).
