Who Invented Heated Blankets?

Heated blankets have become essential for staying warm during colder months. This innovative invention has revolutionized the way people stay warm and comfortable. The concept of heated blankets has been around for centuries, but the modern-day heated blanket is a result of technological advancements in electrical engineering. But who exactly invented heated blankets? Read on to find out.

What are heated blankets?

Heated blankets are electric blankets designed to provide the user warmth and comfort. They heat the blanket through electrical resistance and maintain the desired temperature. Heated blankets come in different sizes and shapes to fit different beds and can also be made from various materials. They are usually controlled by a separate control unit or a built-in thermostat, which allows the user to adjust the temperature to their preference.

Who invented electric blankets?

Electric blankets have been around for several decades, and their invention has been credited to many people. However, the first electric blanket was patented in 1912 by Dr. Sidney Russell of Berlin, Germany. Dr. Russell’s invention was far from the blankets we know today. It was a bulky, heavy, and expensive machine, only available to the wealthy.

When were heated blankets invented?

The date of the invention of heated blankets is unknown, but it is believed that the concept of heating blankets dates back to the 18th century. In the early days, heated blankets were made using materials like feathers, wool, and other natural fibers filled with hot coals or heated stones to provide warmth. However, it wasn’t until the early 20th century that electric heated blankets were invented.

The first electric heated blankets were developed in the 1920s, and they quickly became popular among people who wanted to stay warm during the colder months. Over the years, heated blankets have undergone numerous improvements and innovations, with new materials, technologies, and designs being introduced to the market.

What are heated blankets made of?

Heated blankets are made of various materials depending on the manufacturer and the intended use. The most common materials are fleece, microfiber, cotton, and wool. Some newer, high-tech blankets are made of space-age materials like silk and bamboo. The heating element of the blanket is usually made of thin metal wires, such as copper or nickel-chromium, woven into the fabric of the blanket. These wires are controlled by a thermostat that regulates the temperature, ensuring the blanket stays comfortable and safe.

The outer layer of the blanket is often made of soft, plush materials that are gentle on the skin and provide a comfortable sleeping surface. Some heated blankets are used as a top layer on a regular bed, while others are designed to be used alone as a standalone blanket. Some heated blankets also come with a removable cover, making them easier to clean and maintain.

Heated blanket how does it work?

Heated blankets use electrical current to heat thin metal wires woven into the blanket’s fabric. The wires are connected to a control unit, usually located at the end of the blanket, which regulates the temperature. This control unit has a thermostat that automatically adjusts the heat level based on the user’s preferences.

When the blanket is plugged in, the electrical current flows through the metal wires, heating them and creating a warm surface. The blanket is designed to provide an even distribution of heat across its surface, ensuring the user stays warm and comfortable. The heating elements are often surrounded by an insulating material to prevent overheating and to keep the heat within the blanket.

The blanket’s temperature can be adjusted using the control unit, and some blankets come with additional features such as timers, automatic shut-off, and multiple heat settings. Most heated blankets are safe to use, as they have safety features such as overheating protection and automatic shut-off. They are also designed to be low voltage, reducing the risk of electrical shock.

Can you wash heated blankets?

Most heated blankets are machine washable, but it is essential to follow the manufacturer’s instructions to ensure that the blanket remains in good condition. Some heated blankets have removable controls, which can be detached before washing. This helps to protect the controls and prevent damage during the washing process.

When washing a heated blanket, it is vital to use a gentle cycle and a mild detergent. Avoid using bleach or fabric softeners, as these can damage the heating elements and reduce the effectiveness of the blanket. It is also essential to avoid overloading the washing machine, as this can cause the blanket to become tangled and damaged.

After washing, it is important to air dry the blanket thoroughly before using it again. Do not use a clothes dryer or any other direct heat, as this can damage the heating elements and reduce the lifespan of the blanket.

Are heated blankets safe?

Heated blankets are generally safe to use as long as they are used according to the manufacturer’s instructions. Most heated blankets are equipped with safety features such as overheat protection and automatic shut-off, preventing overheating and reducing the fire risk.

It is important to use a low-voltage blanket, as these are less likely to cause electrical shock. Also, avoiding using the blanket with any damage or frayed damage is important, as these can pose a safety risk.

Following safe sleeping practices when using a heated blanket is also essential. Do not use the blanket with any loose bedding, such as loose sheets or comforters, as these can become entangled in the heating elements. It is also important to avoid using the blanket with any pets or young children, as they may accidentally damage the heating elements or pose a risk of overheating.

What are heated blankets good for?

Heated blankets are good for a variety of purposes, including:

  • Providing warmth: Heated blankets are designed to provide warmth and comfort, making them ideal for use during the colder months. They are especially useful for people who struggle to stay warm, such as the elderly or those with medical conditions.
  • Relieving pain and discomfort: Heated blankets can help to relieve pain and discomfort associated with conditions such as arthritis, muscle aches, and menstrual cramps. Heat therapy can also help to reduce stress and tension.
  • Improving sleep: Heated blankets can help to improve sleep quality by providing a warm and comfortable surface. This can help reduce the frequency of waking up at night, leading to a more restful and rejuvenating sleep.
  • Soothing sore muscles: Heated blankets can help to soothe sore muscles after exercise or physical activity. Heat therapy can help to increase circulation and reduce muscle tension, promoting faster healing and recovery.
  • Providing comfort during outdoor activities: Heated blankets are also useful for outdoor activities such as camping or picnicking, as they can provide warmth and comfort even in cold weather.


Over the years, various people have improved the design and functionality of heated blankets. Today, heated blankets come in various sizes, shapes, and materials, making them versatile and essential for staying warm and comfortable. Despite the uncertainty of the inventor, the heated blanket has become an indispensable item for many households, and it is safe to say that it has made life a lot more comfortable for millions of people.
