How to Use a Heated Blanket: Electric Blanket Care & Buying Tips

There’s cold, and then there’s that cold. The kind that settles into your bones just as you're thinking about slipping into bed. You could throw on another jumper or bury yourself under a pile of duvets. But sometimes, you want something easier. Something that actually works.

That’s where heated blankets come in.

If you’ve never used one before, it’s normal to have a few questions. Are heated blankets safe? Can you sleep with them on? And how hot do they get?

This electric blanket guide answers all your burning questions, from daily use to washing and storing it properly, plus tips on picking the right size and style.

Whether you're cutting back on the central heating or just want to feel snug and cosy this winter, here everything you need to know about using an electric heating blanket.

How to Use a Heated Blanket Safely (Step-by-Step Guide)

Heated blankets are easy to use, but the small details make all the difference when it comes to comfort, safety, and lifespan.

Here’s how to use a heated blanket safely:

1. Lay it flat. Whether it’s on your bed or draped across the sofa, make sure it’s smooth and evenly spread out (no folds or bunching).
2. Connect the controller. Before switching it on, plug the controller securely into the blanket. You’ll feel a firm connection when it’s in place.
3. Power up. Choose your preferred setting using the remote. Vonhaus electric blankets include multiple heat levels, so you can adjust to suit your space and routine.
4. Wait a few minutes. The warmth builds gradually, usually within 5 to 10 minutes, depending on your setting and surface.
5. Switch it off when not in use. Or make use of the built-in timer to turn it off automatically after a set time. It’s safer and more energy-efficient that way.

If you're using it in bed, place the blanket above your fitted sheet. That way, the heat spreads more evenly and it stays comfortable for longer.

Are Heated Blankets Safe?

Every Vonhaus electric blanket is built with safety features designed to shut things down before there’s ever a risk. That includes overheat protection and auto-off timers, which cut the power after a set time even if you forget to.

Where to Use a Heated Blanket

Think heated blankets are just for beds? Think again. They slot into all kinds of cosy corners in your home: 

• On the sofa: Drape your heated blanket over your lap or shoulders while you binge your favourite show. Our Luxuirous Heated Throw (available in grey, pink, and emerald green) is ideal here: soft, flowing, and not at all bulky.
• At your desk: If your legs go numb under your desk, wrap one of these blankets around them instead of cranking up the radiator. More targeted warmth, less waste.
• In bed: Use the electric blanket to preheat your sheets or leave it on low with the timer. It warms the air around you, not just a patch of fabric.
• On your feet: Say goodbye to cold feet with the super cosy Vonhaus Electric Foot Warmer. It’s perfect for slipping your feet into while reading or working – six heat settings, plush fleece lining, and safety features like auto shut-off. It’s an ideal companion to a blanket when full-body heat isn’t needed. 

No matter where or how you use your electric heated blanket, the rules stay the same: lay it flat, avoid tucking into tight folds, and don’t pile heavy layers on top while it’s running. Keep airflow where the wires are, and you’ll guarantee both performance and safety.

How Hot Does a Heated Blanket Get?

All Vonhaus heated blankets give you multiple heat levels (typically up to nine), so you can fine-tune your warmth night by night.

At the highest setting, most heated blankets will reach around 40 °C (give or take). That temperature is generally enough to remove the chill from a cold night without feeling stifling. But it really depends on the model, fabric, how taut the blanket is laid out, and room temperature.

If you’re not sure where to start, try a mid-level setting (like 4–6) and see how it feels. Then you can nudge it up or down as needed – slow adjustment is safer and more comfortable than jumping straight to max.

• If you're sharing a bed and find yourself in a heating tug-of-war, check out the King Size Multi Zone Electric Blanket. Dual heating zones and controls let you and your partner set each side of the bed to your desired temperature. No more blanket battles! 
• Have a smaller bed or just want to snuggle up solo? We have a Double Multi Zone Electric Blanket, too!

Can You Leave an Electric Blanket on All Night?

In short: yes, as long as your blanket has built-in safety features and you’re using it as intended.

All Vonhaus heated blankets and throws come with automatic shut-off timers, typically ranging from 1 to 9 hours. That means they’re designed to switch off safely, even if you forget. For many people, setting the timer and leaving the blanket on overnight works perfectly, especially on lower heat levels.

That said, constant overnight warmth isn’t for everyone. Plenty of users prefer to switch it on 20–30 minutes before bed, then turn it off once the sheets are warm.

If you share a bed with someone who sleeps at a completely different temperature to you (and refuses to compromise), the King Size Multizone Electric Blanket is a gamechanger. It has dual controls, so each side of the bed can be adjusted independently – no more negotiating under the covers.

Washing and Caring for Your Heated Blanket

Yes, you can wash electric blankets – and no, it’s not as complicated as it sounds.

All Vonhaus heated blankets come with detachable controllers, so once those are unplugged, the blanket itself can be machine washed just like any other household fabric. That said, there are a few rules worth sticking to:

1. Unplug everything first. Always remove the controller and any electrical connections before washing your electric blanket.
2. Check the care label. Most Vonhaus electric blankets can be washed at 30°C, but your label will tell you exactly what’s safe for your model.
3. Air dry only. Don’t tumble dry or wring it out. Just lay it flat and let it dry naturally to avoid damaging the internal wires.

You don’t need to wash your electric blanket after every use. A gentle shake or spot clean will usually do the trick – and the less you wash it, the longer it’ll last.

Storing Your Heated Blanket in Warmer Months

When spring arrives and your heated blanket goes back into hibernation, storing it properly will help preserve its shape, performance, and safety.

Here’s what to do:

• Let it cool completely before packing it away.
• Fold it gently without creating tight creases or bends to protect the internal wiring.
• Use a breathable storage bag, like cotton or fabric, to prevent moisture build-up over time.
• Store the controller separately in a dry spot, away from anything that could knock or crush it.

Take a little extra care now, and your electric blanket will be ready to do its job just as reliably when winter rolls around.

Buying Guide: Choosing the Right Size and Style

Not all heated blankets are built for the same job. The right one for you depends on where and how to use your electric blanket. Here’s a quick overview of the different types to find the best option for you:

• Electric underblankets are designed for beds. They sit beneath your top sheet, warming the surface before you get in. Ideal for pre-heating your mattress on cold nights.
• Heated throws are more versatile. Drape one over your shoulders, across your lap, or around your legs while you read, relax, or work from home. Great for sofas, armchairs, and everyday use.
• Multi-zone electric blankets are perfect for couples who like different temperatures. With two separate controls, each side of the bed can be set just how you like it.

Vonhaus electric blankets are available in a full range of sizes, from single to king. So, whether you’re kitting out the spare room or upgrading your cosy winter setup, there’s a snug solution for you.
