You’re freezing. Your landlord hasn't turned the heat up, or maybe that one guest bedroom feels like a meat locker. Either way, you're hovering over your laptop waiting for a Black Friday space heater deal to drop so you can finally stop wearing three layers of wool indoors. It makes sense. Why pay full price for a plastic box that blows hot air when you can get it for 40% off during the November madness?
But honestly, most people buy the wrong one.
They look at the price tag, see a bright red "Sale" sticker, and click buy without thinking about square footage, wattage, or whether that specific unit is actually going to smell like burning dust for three weeks. Shopping for heaters during the holidays is a minefield of overstock clearances and "special edition" models that were manufactured specifically to be sold cheap on a pallet in the middle of a big-box store aisle.
If you want to stay warm without burning your house down or spiking your electric bill to $400, you need to know what you’re actually looking at.
The Myth of the "Energy Efficient" Space Heater
Let’s get one thing straight: nearly all electric space heaters are exactly the same level of "efficient."
Whether you buy a $15 ceramic fan or a $300 "infrared wooden console" that looks like 1970s furniture, they almost all pull a maximum of 1,500 watts. This is a hard limit based on the standard 120-volt household circuit in the United States. If a manufacturer claims their Black Friday space heater is "50% more efficient than the competition," they are basically lying to you. 1,500 watts in equals a specific amount of heat out (about 5,118 BTUs). That’s just physics.
The real difference lies in how that heat is delivered.

Ceramic heaters use a fan to blast hot air. It feels great immediately, but the second you turn it off, the room goes cold. Oil-filled radiators take forever to warm up. You'll be sitting there shivering for twenty minutes. But once they’re hot? They stay hot. They provide a steady, silent warmth that doesn't dry out your sinuses as much as a forced-air fan does. Then you have infrared heaters. These don't heat the air at all; they heat you. It’s like standing in the sun on a cold day. If you’re sitting at a desk all day, infrared is your best friend. If you’re trying to keep a nursery warm, an oil-filled radiator is the gold standard for safety and consistency.
Watch Out for the "Black Friday Special" Models
Retailers like Walmart, Target, and Best Buy often commission specific model numbers just for the holiday season. You might see a brand name you trust, like Lasko or Honeywell, but the model number is slightly different from the one that has 5,000 five-star reviews on Amazon.
Why does this matter?
Often, these "doorbuster" units have shorter power cords, cheaper plastic housings, or—most importantly—they lack a tip-over sensor. Never, ever buy a heater that doesn't have an automatic shut-off if it gets knocked over. Your cat, your toddler, or your own clumsy feet will eventually tip that thing over. If it keeps running while face-down on a shag carpet, you’re looking at a structure fire in minutes.
Always check the specs on a Black Friday space heater for "overheat protection" and "tip-over switch." If the listing doesn't explicitly mention them, skip it. No discount is worth your house.
The Best Brands to Actually Watch This Year
If you're scanning the ads, look for names that have a track record of longevity. Vornado is a favorite among enthusiasts because their "vortex" technology actually circulates the air in a room rather than just creating a hot spot right in front of the unit. They’re usually pricier, so a Black Friday discount on a Vornado AVH10 or a TAVH10 is a genuine win.

De'Longhi dominates the oil-filled radiator market. Their Dragon4 series is a beast. It’s heavy, it’s slow to start, but it’s the most comfortable heat you’ll ever experience in a bedroom. If you see the De'Longhi Comfort Temp models on sale, grab one.
On the budget side, Dreo has been killing it lately. Their PTC ceramic heaters are surprisingly quiet and have much better thermostats than the cheap-o brands you’ve never heard of. A lot of the $30 heaters you see on Black Friday have "dumb" thermostats—they just run until the room is a sauna, then turn off until it’s a fridge. Dreo’s digital logic is a bit more refined, keeping the temp stable.
Where to Put Your Heater (And Where Not To)
You’ve got your deal. It’s sitting in a box on your porch. Now what?
First, throw away the extension cord. Seriously. Do not ever plug a space heater into an extension cord or a power strip. Most extension cords aren't rated to handle a continuous 1,500-watt draw. They will get hot. They will melt. They will start a fire behind your couch where you can't see it until it's too late. Plug it directly into the wall outlet.
Keep the "three-foot rule" in mind. Three feet of clearance on all sides. That means no curtains, no bedding, no stacks of mail, and no laundry drying on top of the unit. It sounds like common sense, but the NFPA (National Fire Protection Association) reports that space heaters account for 44% of home heating fires.
The Math: Is It Actually Saving You Money?
A lot of people buy a Black Friday space heater thinking they’ll save money by turning down their central furnace. This is "zone heating." It works—if you do it right.

If you turn your whole-house thermostat down to 62°F and use a space heater to keep your home office at 70°F while you work, you’ll likely see a drop in your gas or electric bill. However, if you leave the space heater running in an empty room, or if you try to use three space heaters to warm a whole floor because your furnace is broken, you are going to get absolutely crushed by your utility company. Electric resistance heat is one of the most expensive ways to warm a home.
Smart Features: Worth the Extra Cash?
You’ll see a lot of "Smart" heaters this year with Wi-Fi connectivity and app support. Are they a gimmick? Kinda. But they’re a useful gimmick.
Being able to check your phone at 10:00 PM to make sure you actually turned the heater off in the basement is a massive peace-of-mind upgrade. Some Govee or Atomi models allow you to set complex schedules so the heater kicks on 15 minutes before you wake up and shuts off the moment you leave for work. If that prevents you from accidentally leaving a 1,500-watt appliance running for 10 hours while the house is empty, the "smart" tax pays for itself in one season.
How to Spot a Fake Deal
Prices fluctuate wildly in the weeks leading up to the holidays. A common tactic is to raise the "MSRP" in October so the "40% off" discount in November looks more impressive. Use a tool like CamelCamelCamel (for Amazon) or Honey to look at the price history. If that $80 heater was $65 in September, the $70 Black Friday "deal" isn't a deal at all.
Also, look at the warranty. A reputable company will give you at least a one-year or two-year replacement warranty. If the box says "90-day limited warranty," it’s a sign the manufacturer doesn't expect the internal heating element to survive more than one winter.
Actionable Steps for Your Shopping Trip
- Measure your room first. A small ceramic heater won't do anything for a vaulted living room. You need to know the square footage to match the heater's capability.
- Check your outlets. If you live in an old house with two-prong outlets or loose-fitting sockets, a high-draw appliance like a space heater can cause an electrical arc. Have an electrician check your wiring if the plug feels hot to the touch after 20 minutes of use.
- Prioritize safety tech. Look for the UL (Underwriters Laboratories) or ETL label on the box. This means the device has been independently tested for safety. If it doesn't have one of those stickers, put it back on the shelf.
- Buy for the noise level. If this is for a bedroom, avoid cheap fan-forced heaters. They sound like a jet engine taking off. Go for an oil-filled radiator or a high-end "DC motor" fan heater which is significantly quieter.
- Clean it. If you’re pulling last year’s heater out of the garage instead of buying a new one, use compressed air to blow the dust out of the heating elements. Dust is flammable, and that "smell" of a first-time start-up is literally dirt burning off.
Don't wait until the first polar vortex hits to start looking. By then, the good units—the ones with the solid thermostats and the quiet fans—will be sold out, leaving you with the noisy, dangerous leftovers.
Start tracking the prices on a Vornado or a De’Longhi now. When the price drops on Friday morning, you’ll know exactly which one to grab without having to guess if it's a piece of junk or a life-saver.
