Can You Cover an Electric Blanket With Sheets & Duvets?

Some electric blankets are designed to be used under sheets, while others are made for use over the covers. But when can you cover an electric blanket with sheets, and when should you avoid covering it? And how can you prevent your electric blanket from overheating or getting damaged? 

You can cover most electric blankets with sheets and duvets as long as the blanket has a thermostat, is in good condition, and has an anti-overheating design. Always follow the instructions on the blanket’s label to prevent damage.

Electric blanket sheets are designed with safety controls, but this doesn’t mean you shouldn’t take precautions while using one. Wet or damaged electric blankets are the most dangerous since they can cause shocks or fires. Exposed wiring and old or second-hand electric blankets can also pose risks. Let’s look at how you can use your electric blanket safely.  

Can You Put a Cover on an Electric Blanket?

You can put a cover on an electric blanket (on Amazon) if it has a thermostat and the manufacturer’s guidelines allow for it. Most electric blankets are designed to be used underneath covers, but some may overheat if you put a cover over them. 

If you have an electric under-blanket or mattress cover, there’s no harm in placing covers. These blankets are designed with heat sensors and will automatically switch off when the blanket goes above a certain temperature. Most modern over-blankets have the same setting. 

However, if you have an electric blanket designed only to be used over the covers, don’t place it under the covers, or it may overheat. While the best electric mattresses are designed with overheat protection anyways, it’s best to use the blanket according to the manufacturer’s recommendations. 

If you have an older electric blanket, you’ll have to take special care to place it on top of the covers since these blankets have a high risk of overheating. 

Where Should You Put an Electric Blanket on the Bed?

Electric blankets either go under the duvet and above the mattress or above the covers. While different manufacturers have various “optimal” settings for electric blankets, most electric blankets can be classified as either over-blankets or under-blankets. Some people prefer to use both for optimal heat, but one should be enough with the correct heat settings. 

Over-blankets should be placed above the covers. You can cover the blanket with a sheet to avoid touching the blanket directly, but don’t use a heavy sheet that may cause the blanket to overheat. 

Heated mattress covers (on Amazon) and electric blankets that are fitted onto the bed are designed to be used under the covers and sheets. Place the blanket on a sheet directly on top of the mattress and place the sheet on top of the mattress for protection.

Some electric blankets are designed to be placed in the middle of your bedding, so check the guidelines before making your bed. 

Also, avoid placing the electric blanket directly on top of the mattress, as this could cause the material to get damaged. Rather, place a sheet or mattress cover on the mattress and fit the blanket on top. 

What Shouldn’t You Do With an Electric Blanket?

Using an electric blanket in the wrong place isn’t a major risk unless you’re using an older blanket. Most electric blankets have to overheat protection and can be used under or over the covers. However, electric blankets carry a few risks, even with all the safety measures. 

To reduce the risk of fire or burns from electric blankets, follow these tips: 

  • Use the blanket as directed on the label. Most electric blanket burns happen from improper use. 
  • Keep the electric blanket away from water. Just as with most electric appliances, electric blankets will get damaged if switched on when wet. It could also cause short-circuiting and result in an electric shock. 
  • Avoid folding the blanket since it can damage the wiring. When you fold the blanket, the delicate wiring may bend, and electrical components may get damaged. Rather, roll the blanket carefully to prevent wire damage. 
  • Don’t use a damaged electric blanket. Electric blankets with damaged or exposed wires have a high fire risk and may burn your skin. This is why you should always use a sheet under the blanket.
  • Avoid using old or second-hand electric blankets. Even if an old blanket is in good condition, it’s still a risk since older blankets don’t have the same overheating protection and have a higher risk of burning.
