What is the best material for an adjustable electric blanket?

A wide array of fantastic materials is available in adjustable electric blankets. These are fire-resistant while also providing a comfortable and soft surface that distributes heat evenly. However, it’s usually going to be some version of polyester that will appear in the form of fleece, faux fur or micro plush fibre.

What to look for in a good adjustable electric blanket?

Aside from appearance, size and price, you also want to keep your eye out for the materials it comprises its wiring construction, the voltage, the number of adjustable settings and other technical specs.

Different Settings

The most important component of an adjustable electric blanket is the number of available settings. Some have a basic on-off switch and yet others have three settings: low, medium or high.

There are others with seven to as many as 10 settings or more. Some manufacturers list these as numbers while ones that are more luxurious offer programmable heat settings. These controls attach to the blanket by a wire for ease of use.

Material Quality

While almost all modern adjustable electric blankets will have quality fire-resistant materials, some will be cheaper and scratchier than others. It’s safe to say that almost all will have some type of polyester, but some still incorporate itchy acrylic. In the rare chance, a manufacturer makes theirs with cotton, run fast and far; cotton is highly flammable.


The price of an adjustable electric blanket can run the gamut depending on overall engineering, materials, size and rarity of features. They can be as little as £25 for something the size of a typical throw blanket with simple controls. But, electric blankets can cost as much as £150 or more for a king-size with all the fancy features.

Blanket Features

Adjustable electric blankets have many safety features to consider things as automatic shutoff, timers and dual controls. Some people may want to focus their attention on overall weight along with insulation capability. Also, the position of the blanket’s cord and the controller will be important for placement and orientation.

Automatic shutoff is often standard with most modern electric blankets. It’s not uncommon to see a blanket stay on for eight to 10 hours before turning off on its own. But you should always ensure this is something the company promotes and advertises.

In regards to timers, there’s a world of options in this arena. You can get programmable ones that turn on before bed or you can manually adjust how long the timer stays on. Dual controls are excellent when sharing the blanket with another. It means you can have conditions on how you like them while your partner can set their side to what they prefer.

Voltage/Cost to Run

The amount of voltage an electric blanket has will affect how much it costs to run. Some with intricate settings will have variable voltage ranges, which means running costs will differ depending on the setting. Some have built-in transformers to regulate the voltage from the outlet.

Others feature low voltage. This means it will take a while for the blanket to warm up. However, it will be the least expensive to run.

Cleaning Features

Most adjustable electric blankets are machine washable, but make sure the manufacturer prominently lists this. Also, each model will have specific care and washing instructions, so follow those accordingly.

Are electric blankets affordable to run?

Electric blankets are affordable to run and they have the potential to lower heating bills. With inflation being what it is, an adjustable electric blanket might be the perfect solution. 

The average adjustable electric blanket has a range of around 40 to 60 watts on a medium setting. King-sized ones can be as much as 100 to 200 watts. But, for the sake of example, let’s say you have one with 100 watts.

If you leave it on for eight hours, it will only use 0.8 kilowatts per hour (kWh). Since the average cost for a typical home is about £0.28 per kWh, this translates to approximately £0.20 to run the electric blanket all night.
