Space Heaters
every plug-in heater on this sheet runs on the same household outlet, so this table skips the wattage and lines them up on the things that actually differ: what kind of element they use, how much they weigh, whether they sweep the room, how exactly you can set the temperature, and how long the maker backs them. sort any column, then open a row's ai score to see why it landed where it did.
 BLACK+DECKER BHDC201 Personal Ceramic Heater | 6.4 A cheap desk heater that adds the tip-over switch the Lasko cube lacks, limited to spot heating with a vague knob and short warranty. | Ceramic | 2.8 lb | 1 yr | |||
|---|---|---|---|---|---|---|---|
 Comfort Zone CZ442E Personal Ceramic Heater | 5.9 Has the safety basics for a desk or nightstand, but a vague knob, the shortest warranty and no independent testing. | Ceramic | 2.5 lb Retailer-listed weight. | 1 yr | |||
 De'Longhi ComforTemp EW7707CM Oil-Filled Radiator | 7.6 A proven, silent bestseller radiator with a solid warranty, but a mechanical dial and no timer leave temperature control to guesswork. | Oil-filled | 23.4 lb | 3 yr | |||
 De'Longhi Dragon Digital TRD40615E Oil-Filled Radiator | 8.3 The silent bedroom heater done right: exact 1-degree set points, ECO mode and a timer on a radiator, if you accept slow warm-up and 25 pounds. | Oil-filled | 25.6 lb | 3 yr De'Longhi US lists a 3-year limited warranty; some older Dragon manuals state 1 year. | |||
 De'Longhi Dragon4 TRD40615T Oil-Filled Radiator | 6.8 Silent and steady, but Consumer Reports found it slow to warm a seated person with a hot exhaust, and the digital sibling fixes its dial. | Oil-filled | 24 lb | 3 yr De'Longhi US lists a 3-year limited warranty; some older Dragon manuals and Consumer Reports list 1 year. | |||
 Dr. Infrared Heater DR-968 Portable Space Heater | 7.3 Quiet, gentle heat with a remote and a long warranty, offset by 19 pounds, settings that reset after outages and some thermostat-accuracy complaints. | Infrared | 19 lb | 3 yr | |||
 Dreo Atom One Space Heater | 8.1 A digital thermostat and oscillation in a quiet, tiny, cheap box that owners love; no lab test yet and only one winter of warranty. | Ceramic | 3.8 lb | 1 yr | |||
 Dreo Solaris Slim H3 Tower Space Heater | 8.5 Bob Vila's tested best overall: quiet, precise in 1-degree steps and punches above its size, held back only by fiddly controls and a one-year warranty. | Ceramic | 4.6 lb | 1 yr | |||
 Dreo WH719S Smart Wall-Mounted Space Heater | 7.1 The only app and voice control here and quiet in small rooms, but it needs drilling, struggles in big rooms and has confusing buttons. | Ceramic | 9.2 lb Retailer-listed weight. | A motorized louver sweeps the airflow; the wall-mounted body does not rotate. | 1 yr | ||
 Duraflame 3D Infrared Electric Fireplace Stove Heater | 6.6 You're paying for the convincing flame show; the heat is ordinary, the legs are plastic and the warranty lasts one year. | Infrared | 28.6 lb | 1 yr | |||
 Honeywell HCE322V Digital Ceramic Tower Heater | 7.4 Light, well-reviewed tower with a real set-point thermostat and tip-over switch, but no remote and an audible fan. | Ceramic | 4.4 lb | 3 yr | |||
 Honeywell HCE323V Safeguard Motion Sensor Ceramic Heater | 8.0 Strong room heating in Consumer Reports' testing plus remote, timer and a motion-sensor safety layer; its fan is among the louder ones. | Ceramic | 4.6 lb | 3 yr | |||
 Honeywell HCE840B HeatGenius Ceramic Heater | 7.0 Clever floor, personal and room modes with a precise thermostat, but it doesn't oscillate and costs more for the same output. | Ceramic | 5 lb Consumer Reports' listed weight. | 3 yr | |||
 Honeywell HHF360V 360 Degree Surround Heater | 6.1 Durable and cheap with a good warranty, but Tom's Guide measured it as the loudest heater it tested and it only warms a small zone. | Fan-forced coil Retailers describe a fan-forced wire element. | 4.2 lb Consumer Reports' measured weight; Honeywell does not publish one. | Blows heat in all directions at once instead of oscillating. | 3 yr | ||
 Lasko 751320 Ceramic Tower Space Heater with Remote Control | 7.2 One of Amazon's most-bought heaters for good reason, but the indicator-light thermostat is vague and Lasko lists no tip-over switch. | Ceramic | 5.7 lb | Set points are chosen by button or remote and shown with indicator lights, not a numeric readout. | 3 yr | ||
 Lasko 754200 Ceramic Portable Space Heater | 5.3 A beloved cheap cube that warms only your feet and keeps running if knocked over; Lasko's own 754201 revision fixes that. | Ceramic | 3.2 lb | 3 yr | |||
 Lasko 755320 Oscillating Digital Ceramic Tower Heater with Remote | 7.5 Years of reliable sales and a true numeric thermostat on the remote; no tip-over switch listed and auto mode only on High. | Ceramic | 7.3 lb | 3 yr | |||
 Lasko FH500 DUO Comfort Tower Fan and Ceramic Space Heater | 8.8 Tom's Guide's room-heating winner, with a real set-point thermostat and tip-over switch, plus a summer tower fan that earns its 42-inch footprint. | Ceramic | 11.5 lb | 3 yr | |||
 Pelonis PTH15A4BGB Ceramic Tower Space Heater | 6.3 Feature-rich for a budget tower, but no independent testing, inconsistent published specs and a one-year warranty keep it mid-table. | Ceramic | 6.4 lb Converted from the listed 2.9 kg. | 1 yr | |||
 Vornado MVH Whole Room Vortex Heater | 7.7 Quiet, even whole-room heat and the longest warranty here, undercut by an unmarked dial thermostat and no remote or timer. | Fan-forced coil Vornado describes a non-ceramic element; type inferred from the identical VH200. | 4.1 lb | Spreads heat with vortex air circulation rather than oscillating. | 5 yr |
How the AI score works, and who wrote it
A language model rated these, not a test lab. Every score from 1 to 10 is an AI assessment of how good the product is against the other 20 in this comparison, formed from the specifications we verified plus the published lab reviews and owner reception found while researching each one. Nobody at Slopsheets listened to, wore or plugged in any of it.
It weighs the things a spec table cannot show: how a product is actually reviewed, how well the software works, build quality, and what you get for the money. That is deliberate. An earlier version of this column was pure arithmetic on the table and it ranked a bundle of cheap boxes above a class-leading single unit, because counting hardware is not the same as judging it.
Treat it as an informed starting point and read the sourced comparison, not as a verdict. The score is relative to this comparison only, so it means nothing across categories, and it carries no price, star rating or review count. Every specification behind it is sourced and checked; the score on top of them is opinion.
Frequently asked questions
Which column should I sort by first when choosing a space heater?
Start with heater type. Ceramic models warm you fast and weigh little, oil-filled radiators are silent but slow and heavy, and infrared units warm people and objects directly. Once you know the type, filter on the digital thermostat column, since a set-point thermostat holds a room far more steadily than a dial.
Does a heavier space heater put out more heat?
No. Weight on this sheet tracks the type of heater, not its output. Personal ceramic units weigh under 3 lb and oil-filled radiators weigh over 23 lb, yet both top out at the same 1,500 watts. The radiator's extra mass just stores heat and releases it more slowly.
Is app control worth looking for on a space heater?
Only if you want schedules or voice control. Just one heater on this sheet has an app, and its main payoff is starting the heat before you get up or get home. A remote and a timer cover most of the same ground on the other models.
How much does warranty length vary between space heaters?
From one year to five on this sheet. Most brand-name heaters carry three years, several popular budget and newer brands offer one, and Vornado offers five. For a device that runs for hours every day through the winter, that spread is worth sorting on.
Why doesn't this sheet list wattage or heated square footage?
Because wattage is the same 1,500 watts across the board for standard plug-in heaters, and square-footage figures are set by each brand with no common test behind them, so they can't be compared fairly.
