Are Heated Blankets Safe for Your Home?
Heated blankets offer cozy warmth during winter, but are they safe?
4 minute read • Last update November 2025
Electric blankets provide warmth during cold winter months in Texas, but are heated blankets safe to use in your home? Most modern models have built-in safety features, but improper use can pose risks.
This guide covers electric blanket safety in detail, highlighting how they work, potential dangers, and best practices for safe use so you can stay warm.
How do heated blankets work?
Electric blankets use insulated wires inside that generate heat when electricity flows through them. Most models use 60-150 watts and include adjustable temperature controls. Electric blanket wattage typically varies between 60-150, although most have a control unit that allows you to adjust the temperature settings to your preference.
Safety features in modern heated blankets
Many of the dangers of electric blankets apply primarily to older models, as most modern designs have introduced safety features to prevent accidents. For example, many electric blankets are equipped with:
- Auto shut-off mode: The blanket turns off after a specified time to prevent overheating.
- Temperature sensors: The blanket monitors heat distribution and auto-adjusts the current flow to prevent hotspots when maximum heat settings are reached.
- Flame-resistance: Blankets made using flame-resistant materials like fiberglass, Kevlar, Nomex, and wool treated with fire-retardant compounds minimize the risk of electric blanket fires.
In addition to improving heated blanket safety, many newer models are also designed for low power usage, which can help to reduce your electricity costs.
Potential electric blanket dangers to your home
While newer designs include features that improve safety standards, improper use can still pose risks. Here are the top three heated blanket dangers to be aware of.
Fire hazards
Electric blanket fires are most likely if you leave a heated throw on for too long, fold it improperly, or expose it to flammable materials like curtains or bedding. However, worn-out electric blankets can also become fire hazards, especially if they have damaged wires or frayed cords.
Overheating
While many newer models include features that reduce safety concerns, using an electric blanket for extended periods can increase the risk of overheating. If you fall asleep on a bunched-up blanket with heat concentrated on one part of your body, you are at higher risk of burns.
Electrical issues
As with any other electrical appliance, old or damaged circuitry can lead to malfunction, and failure to follow well-established electrical safety tips could cause damage to your home’s power supply. Using a heated blanket with damaged cords or plugging it into an overloaded power strip increases the risk of short circuits.
How much electricity does an electric blanket use?
Like other devices, your heated blanket energy usage is measured in kilowatt-hours (kWh). The precise wattage of your blanket will depend on its size and model. For example, queen and king sizes designed for use on your bed will likely range from 100-150 watts, whereas the smaller twin blankets you’d use to stay cozy on the couch or in a recliner chair may use only 60-100 watts.
If you like knowing how to reduce your energy bill, you’ll likely want to see the effect on your utility costs if you use an electric blanket regularly. Regardless of size, the power draw of any electric blanket is minimal. Even if you left one on for several hours, the cost would be relatively insignificant—typically between 1-3 cents per hour or $0.10–$0.20 per night.
Electric blanket safety tips
Follow these safety tips to prevent accidents:
- Only buy a blanket certified by a reputable testing agency like UL or Intertek.
- Follow the manufacturer’s directions for cleaning, storage, and instructions for proper use.
- Check for signs of wear and tear regularly, and never use a heated blanket with frayed wires, exposed cords, or charred spots.
- Avoid sitting on an electric blanket. Use a heating pad instead if you require under-body heating.
- When using an electric blanket to heat your bed, turn it off (or set a timer to turn it off) before you sleep.
- Turn off and unplug after use whenever it’s feasible.
- Only use one blanket at a time. Layering multiple blankets for additional warmth can cause overheating.
- Never fold an electric blanket. Instead, store it flat or rolled to avoid damaging the wires inside.
- Avoid placing your heated blanket near flammable materials like curtains, mattresses, sofas, or other upholstery.
Implementing these tips will help you stay cozy with confidence and enjoy your heated blanket worry-free.

FAQs
Browse our FAQs below for a quick recap and final thoughts on electric blankets, bad practices to avoid, and recommendations for use around children and animals.
Are electric blankets safe for children to use?
Yes, generally speaking. However, kids should not be permitted to use an electric blanket or select heat settings without supervision.
Do electric blankets use a lot of electricity?
No, most heated blankets are low-power and cost little to run, making them a popular alternative to heating an entire room.
Are electric blankets dangerous for pets?
They can be, yes. So, if you have pets that may chew on the wires and risk receiving an electric shock, it’s usually better to consider more pet-friendly alternatives.
Are electric blankets washable?
Yes, most electric blankets are machine washable, provided you check the care label and follow the instructions carefully. However, you should never dry clean a heated throw because the solvents involved may damage the inner wiring.
Do electric blankets cause fires?
While rare when used as intended, electric blanket fires can occur when blankets are old, damaged, or used incorrectly.
Are heated blankets safe to sleep with?
Many are, but if you don’t have a design with an auto shut-off, experts recommend preheating before bedtime and switching off when you turn in.
Are electric blankets energy-efficient?
Yes. Electric blankets use less energy than heat pumps and other stand-alone heating devices like space heaters.
How do you store an electric blanket safely?
Store flat or rolled up to avoid damaging the wires inside, and never fold or place heavy objects on top of an electric blanket.
