Space heaters: every one is 1500 watts, so buy on the other things
The Dreo takes it on the stated thermostat, the Amazon Basics does the same job for less, and only the two towers and the infrared cabinet change how the heat is spread.

Side by side
The picks
Dreo Space Heater with thermostat
4.6 across 21,232 ratings, the highest average here, and the listing states a thermostat. Temperature control is the whole argument for spending above the bare-minimum tier.
Watch outThe title states neither oscillation nor wattage, so confirm the spread before buying it for a large room.
GiveBest Portable Space Heater
The largest rating pool on this page by a wide margin, at under thirty dollars. The listing says almost nothing beyond portable and indoor, so the record is doing all the work here.
Watch outNo thermostat, wattage, oscillation or protections stated in the title. Assume none of them.
Amazon Basics Ceramic Heater, 1500 W
The listing spells out a thermostat, overheat and tip-over protection, and gives real dimensions: about nine inches tall. It is the cheapest heater here and produces the same 1,500 watts as anything else on this page.
Watch outNon-oscillating, as the title says. It heats a direction rather than a room.
Black+Decker BHDC201 Personal Heater, 1500 W
A personal ceramic unit rated at 1,500 watts. It does roughly what the Amazon Basics does at a higher asking price, and unlike that listing, its title states no thermostat and no tip-over protection.
Watch outNo struck-through list price either, so there is nothing to judge the asking price against.
WINHL Space Heater, 70-degree oscillation
The 70-degree oscillation is the reason to look at it, since a swept arc warms a seating area instead of one side of one person. Nothing else in the listing stands out, including the brand.
Watch out2,391 ratings is the thinnest record here, too short to show a failure pattern, and there is no brand behind it worth chasing for support later.
Lasko 751320 Ceramic Tower, 23 in
A 23-inch ceramic tower with a remote and more than 40,000 ratings behind it. Tall units release heat higher up and mix a room more evenly than a box sitting on the floor, and that is what the extra money buys.
Watch outIt asks far more than the small units here for the same ceiling on heat output, and the title does not claim oscillation.
Pelonis 23-inch Oscillating Ceramic Tower
The same tower height as the Lasko, with oscillation, a timer and a remote all stated in the title. For four dollars more than the Lasko, that is the more complete specification of the two.
Watch outNo list price, and with fewer ratings than the Lasko behind it, you are paying for the spec sheet rather than the history.
Dr Infrared DR-968, 1500 W cabinet heater
An infrared cabinet unit rather than a ceramic fan, which warms objects and surfaces in its path rather than blowing hot air past them. The same 1,500 watts, delivered in a way that feels different in a large room.
Watch outFive times the price of the Amazon Basics for the same power ceiling, and cabinet units are heavy to move between rooms.
What actually matters here
- 01Nearly every plug-in heater sold in the US tops out at 1,500 watts, because a 15-amp household circuit cannot safely carry more. Two heaters at that rating make the same heat, so the price is buying controls and distribution.
- 02Plug a heater directly into a wall outlet. Extension cords and power strips are not built for a sustained 12.5-amp draw, and that is where heater fires start.
- 03A thermostat is worth more than an extra heat setting. Cycling the element to hold a temperature uses less power across an evening than running at full output and then opening a window.
- 04Oscillation matters more than it sounds like it should. A fixed unit heats a cone of air; a swept arc raises the temperature of a whole seating area instead of roasting one side of one person.
- 05A listing that does not mention a thermostat, tip-over protection or oscillation is not withholding good news. Read the absence as an absence.
- 06Ceramic, oil-filled and infrared all turn electricity into heat at the same efficiency. The difference is how quickly it arrives and how long it lingers: oil-filled is slow and steady, ceramic is fast and stops the moment it switches off, and infrared warms what it points at.
Questions people actually ask
- Will a space heater lower my heating bill?
- Only if you turn the central heat down and live in the one room the heater is in. Electric resistance heat costs more per unit of heat than gas across most of the US, so adding a heater without lowering the thermostat simply adds to the bill.
- Is it safe to run a space heater overnight?
- Only with tip-over and overheat protection, on a hard flat surface, three feet clear of bedding and curtains, and plugged straight into the wall. Even then, a unit with a thermostat that cycles off is a safer choice than one that runs continuously.
- How many square feet will 1,500 watts heat?
- As a working rule, about 150 square feet of reasonably insulated room, using the usual 10 watts per square foot estimate. Claims of 1,000 square feet assume the rest of the house is already warm. A space heater takes the chill off one room and does not replace central heat.
