Heated Blanket vs Space Heater: Which Costs Less, Which Is Safer?

• A heated blanket uses a small fraction of the power. Of the 27 heated blankets, throws and pads we checked, 5 print their wattage, and they use 100 to 115 watts. A plug-in space heater uses 1,500 watts on high.^[8]
• One night costs about 16 cents vs $2.18. That is 110 watts vs 1,500 watts for 8 hours at 18.19 cents per kWh, the U.S. average for January to July 2026. Over a five-month winter of nights, that is $24 vs $327.^[1]
• Both cost less in real use. These are full-power numbers. A blanket's controller (the plug-in switch with the heat settings) and a heater's thermostat both turn the heat off and on to hold your setting.
• To buy, they cost about the same. Our blanket picks cost $37 to $80. Our space heater picks cost $24 to $70.
• They do different jobs. A blanket warms you, not the room. To warm the whole bedroom, see whether a space heater beats your furnace. For one night where you live, see the table for every state.

• Space heaters are tied to more fires. The CPSC (the federal product safety agency) counts about 1,600 fires and 70 deaths a year from portable heaters (2020 to 2022).^[3] The NFPA, a fire safety research group, puts space heaters and heating stoves in one group. That group causes about 3 in 10 home heating fires but 73% of the deaths from them (2020 to 2024).^[2]
• Old heated blankets are the main blanket risk. The Electrical Safety Foundation, an industry safety group, says heating pads and electric blankets cause almost 500 fires a year. Almost all involve blankets more than 10 years old. Its page gives no year for this count.^[6]
• Neither is meant to run while you sleep. The CPSC says to turn heaters off when sleeping.^[3] UL, the safety lab that tests electric blankets, says to warm the bed with the blanket, then turn it off.^[5]
• So, on a cold night: warm the bed with the blanket, then turn it off and pull your comforter up. If you keep the blanket on, set it to low, put nothing on top of it, and let the auto shut-off be your backup.^[4]
• Recalls are common. Since January 2025, the CPSC has recalled about 381,560 heated blankets and throws from JKMAX, OCTROT, MaxKare, and warned buyers about Melinora. Check the model number on your blanket's tag or controller against the list below.^[7]

Heated blankets recalled since 2023

From each recall page on cpsc.gov, read October 17, 2026. Space heater recalls are on our space heater page.

Use a heated blanket safely

• Lay it flat. Don't tuck it in, fold it, or pile blankets or pets on top of it. Let the edges hang over the sides of the bed.^[4]
• Check it each fall for dark, charred or frayed spots and a cracked cord. Replace an old or worn one.^[6]
• Don't use one for a baby, a young child, or anyone who can't work the controls. People with diabetes burn more easily.^[5]
• Never buy a used electric blanket.^[5]

Each pick's own listing states its wattage, a UL or ETL mark (labs that test products to safety standards) and an auto shut-off. Among those, it is the top seller of its type on Amazon. We checked each model number against every recall below.^[8]

Bedsure recalled about 350,000 blankets and pads sold in late 2022 (models BS-HB5060, BS-HB6284, BS-HB7284, BS-LV0A and pads BS-HP1224, BS-HP2433, BS-HP2422). The Bedsure models picked here are newer and not on that list; each card shows its model number. On a blanket you own, the model number is on the tag and the controller.^[7]

One night = watts ÷ 1,000 × 8 hours × the state's average home electricity price (EIA). Winter = 150 nights.

• You need the room warm, not just you. Getting dressed, working at a desk, or a cold bathroom. A blanket can't do that.
• Someone else wants the room warm. A blanket only warms the person under it. A partner who won't use one may want the heater on while you're both awake.
• You're awake and in the room. Run it while you're there, and turn it off when you leave or go to bed.^[3]
• Buy one with a thermostat, tip-over shutoff and a UL or ETL label. See our space heater picks, and why a pricier heater doesn't make more heat.

How much does it cost to run an electric blanket all night?

A 110-watt queen blanket on high for 8 hours uses 0.88 kWh: about 16 cents at the U.S. average of 18.19 cents per kWh, or $24 for a five-month winter of nights. That is the most it costs. The controller turns the heat on and off to hold your setting, so on low it uses less. ^[8][1]

Do electric blankets use much electricity?

No. The heated blankets, throws and pads we checked that state their wattage use 100 to 115 watts. A plug-in space heater uses 1,500 watts on high, about 14 times more. ^[8]

Is it safe to sleep with a heated blanket on all night?

UL says to use the blanket to warm the bed, then turn it off before you go to sleep. If you leave it on, use a blanket with an auto shut-off, keep it on low, and never tuck it in, fold it or pile other blankets or pets on top of it. Do not use one for a baby, a young child, or anyone who cannot work the controls. People with diabetes should take extra care: they burn more easily. ^[5][4]

Is it safe to sleep with a space heater on?

No. The CPSC says to turn heaters off when sleeping. Keep a heater 3 feet from bedding and furniture, and plug it straight into a wall outlet, never a power strip or extension cord. ^[3]

Heated blanket or heated mattress pad: which is better?

They use about the same power: the pad we list uses 100 watts. A pad heats you from below, under your sheet. A blanket can also go on the couch. For a bed shared by two, pick one with dual controls. ^[8][4]

Is a heated blanket safe for an older adult?

Yes, if they can feel heat and work the controls. The CPSC home safety checklist for older adults says to lay the blanket flat, never tuck it in, and keep everything off the top of it. UL warns that people with diabetes burn more easily, and that anyone who cannot work the controls should not use one. ^[4][5]

Can I use a heated blanket and a space heater together?

Yes, one after the other. Run the heater while you get ready for bed, turn it off when you lie down, and let the blanket keep you warm. The CPSC says to turn heaters off when sleeping, and UL says to turn the blanket off once the bed is warm. ^[3][5]

Is a heated blanket the same as an electric blanket?

Yes. Both names mean a blanket with heating wires inside and a plug-in controller.

Has my heated blanket been recalled?

Check the model number on the tag or controller against the recall list on this page. Since 2023, the CPSC has announced 6 recalls of heated blankets, throws and pads, plus one warning. Never buy a used electric blanket. ^[7][5]
