"In Consumer Reports’ space heater tests, we found multiple models that work well and even look good."

"We also found that you don’t have to pay a premium for top performance—many models we rate highly cost less than $100."

"A machine that makes a racket can be annoying if you’re running it while trying to watch TV (or work)."

"The oil-filled radiator-style 1,500W De’Longhi electric heater features a digital control panel with programmable settings, timers, and high-low automatic temperature settings. It has thermal chimneys that allow cold air to pass through the fins more effectively, heating the room faster and more evenly through quiet convection."

"Digital control panel with timer"

"Programmable settings and thermostat keep spaces consistently comfortable"

"If you’ve got a large space to heat up, you need a heater that can handle the square footage."

"This affordable model from Amazon Basics can heat up to 1,000 square feet—that’s a really big great room."

"And reviewers attest that it is, in fact, great at heating a large space."

"This popular DeLonghi space-heating tower comes with a large digital display that lets you easily see the room's temperature, plus controls that make it easy to adjust the temperature to your liking."

"On top of being quiet, it also includes a tip over feature, automatic shutoff if the room gets too warm, a programmable timer, and a remote that lets you crank the heat up or down without getting up from the couch."

"According to the brand, this heater suits spaces up to 150 square feet in size, so it should be a good fit for bedrooms, smaller living rooms and offices."

"For warmth and peace of mind, consider the ample safety features of the AirNmore Comfort Infrared Space Heater."

"The power level is adjustable, and the heater has a built-in thermostat to maintain a consistent temperature."

"A tiny remote control let us change modes (low or high) and temperatures while working at a desk, and we liked that we could precisely adjust the temperature setting and see it on the display."

"The AirNmore Comfort Deluxe Infrared Space Heater is great for heating up a small space quickly and efficiently."

"Amazon Basics 1500W Oscillating Ceramic Heater is a great choice for large areas."

"The DeLonghi TRD40615E Full Room Radiant Heater is a great choice for those who want to heat a large space quickly and evenly."

"In looking at portable space heaters, are all 1500W heaters the same? Or will some heat more efficiently than others, thereby requiring less actual on-time?"

"Basically, yes. Electricity converts one hundred percent to heat, so (barring losses to run electronics, which even so contribute a bit), 1500 watts of electricity is 1500 watts of heat, period."

"Yes"

"We bought a Honeywell ceramic space heater with fan, close to the HCE860BWM at Walmart."

"Ours would’ve readily heat a good size living room and was still working when we donated it five years later."

"I’d get one that doesn’t oscillate. Less to break."

"How are infrared ones? Something like this..."

"The one you linked has an IR element, but also a fan. So it makes noise, and distributes some fraction of the heat more widely by convection. To maximize the radiant heat--to better be able to feel it on your skin, for example, you would be better off choosing one that doesn't use a fan and is as close as possible to all IR."

"I have one of those fake fireplace IR heaters in the living room. It usually lives about 8-10 feet from the couch and after 15 minutes I can tell it's working."

"Ceramic heaters - can be either radiant (heats people and objects not air), or forced air (heats air which in turn heats people and objects) - very efficient at spot heating but can cycle too hot to too cold depending on distance, room, and thermostat accuracy"

"Convection heater. I had one, could heat the entire 700+

"A heating pad under your feet, and an electric heated throw around your torso and a blanket or something else on top of the throw. You will be toasty, but not throwing off tons of heat into the surrounding air."
