Buying an electric heated blanket: what to look for in warmth, safety and cleaning

An electric heated blanket can warm your bed or sofa without needing to turn up the heating throughout the room. But when choosing one, there’s more to consider than wattage and a soft feel. Look for clear temperature controls, a suitable size, reliable automatic shut-off functions and easy cleaning.

Cheap deals can often lead to avoidable disappointments. Pay particular attention to these three points:

• Unclear shut-off: Some models switch off only after a fixed time, or have a display that’s difficult to read. If you plan to use your blanket as you drift off, a selectable automatic shut-off is more practical.
• Too few heat settings: An electric heated blanket with just one or two settings offers limited flexibility for different room temperatures and personal preferences.
• Difficult to clean: If the controller can’t be removed, the blanket usually can’t go in the washing machine. This can make regular care more of a challenge.

The key things to look for at a glance

1. Heat settings, temperature control and timer

A heated blanket with temperature control should have several clearly distinct heat settings. Ten settings allow for finer adjustments than a simple H/M/L selection. An LED display can make it easier to check the selected setting and timer.

A heated blanket with a timer should ideally offer a choice of shut-off times. It’s also worth checking whether you can set the timer independently of the heat setting. Some products may link a short timer setting to a limited heat setting, so check the instruction manual before buying.

2. Automatic shut-off and safety features

A heated blanket with automatic shut-off helps prevent it from running unnecessarily after use. Other features, such as overheat protection, overcurrent protection or fuses in the controller, are also useful product specifications to consider.

If you’re buying in Germany, also check the technical specifications: 220–240 V, the correct mains frequency and a plug that’s suitable for the socket. Check the cable for damage before use. Don’t use the blanket if it’s folded, badly creased, wet, or has been damaged with pins or sharp objects.

3. Size, where you’ll use it and washability

An electric underblanket is used on or under the bed. It should cover the sleeping area without hanging too far over the sides. Couples may want to consider a double heated blanket measuring 140 x 160 cm, but check that there’s enough room for two people and whether it has separate controls.

For one person on the sofa, a size of around 130 x 180 cm is often enough. If you’re looking for a heated blanket for bed and sofa, also consider its weight, cable length and the position of the connection.

Calling a heated blanket machine washable is only useful if the controller or connection can be fully removed. Unplug the product before washing and make sure it’s completely dry before using it again.

Frequently asked questions about electric heated blankets

How much electricity does an electric heated blanket use?

Consumption depends on the rated power and how long the blanket is actually used. A 60 W model uses a maximum of 0.06 kWh in one hour, while a 180 W model uses up to 0.18 kWh. Actual consumption may be lower depending on the heat setting. To calculate the cost, multiply your electricity tariff by the energy used per hour.

Can you leave an electric heated blanket on all night?

This depends on the manufacturer’s instructions and the automatic shut-off setting. Automatic shut-off is useful, but it doesn’t replace basic safety precautions. Don’t use the blanket if it’s folded, creased, wet or damaged. If you want to use it to warm up as you fall asleep, choose a suitable timer setting and follow the instruction manual.

How should you wash an electric heated blanket?

First, unplug it and fully remove the controller or connection. Then follow the manufacturer’s care instructions. If the blanket is labelled as machine washable, make sure it’s completely dry before reconnecting it. Don’t fold, store or switch it on while it’s damp.
