Are Electric Blankets Waterproof? – Protect From Water

When my electric blanket got wet, I was worried because water could damage the electric heating system in the blanket. After that, are electric blankets waterproof? Was the first question in my mind, and I searched so many things about it and prepared a helpful post about it, including many details.

Are electric blankets waterproof? Electric blankets are made as waterproof to protect the electric system from wetting. It has protected with a specially woven cloth heating element and the form of an insulated wire. Hence electricity will not leak when it gets wet while it plugged into the power supply.

But you should pay attention to some factors when you are using an electric blanket. So it is better to refer this guide until end.

How are Electric Blankets Made as Waterproof?

The electric blanket consists of three main components. Those are;

  • A specially woven cloth called a shell.
  • The heating element in the form of an insulated wire.
  • A bedside control and power cord.

➤ The shell is made by using a blend of polyester and acrylic, which has been formulated for the industry.

➤ The wiring is made by a positive temperature coefficient material. It is heat-producing and heat sensitive along its entire length. Therefore, eliminating the need for thermostats. This is special wiring for this product. It is encased in an insulated jacket made of a proprietary blend of plastic.

➤ The bedside control and power cord – Made of a combination of plastic and metal materials.

➤ Basically, the coil in the electric blanket is covered by thermal insulation, so the heating system of an undamaged electric blanket is waterproof. But the fabric cover of the blanket will absorb water like a normal blanket.

➤ The waterproof electric blanket is manufactured with a noiseless waterproof barrier fused between two layers of soft coral wool.

➤ Some of the blankets are made of premium polyester with cotton padding and it will help to waterproof of blanket.

Breathability and Waterproofness of Electric Blankets

First, if we examine the meaning of the word breathability; it means how much the fabric allows air and moisture to pass through it.

Poorly breathable fabrics can accumulate heat or moisture in the microenvironment inside.

Generally, electric blankets like this are often used in countries or regions with a high cold environment. Therefore, after the electric blanket is activated, the heat generated in it leaks out, the manufacturers work to finish this blanket with a fabric with minimum breathability. Or the heat flows out too quickly, making it difficult to get the desired benefit.

The system of electric blanket is made as waterproof. Otherwise, water enters the system (coil and wire) an electric shock may occur from the system. But the fabric part of the blanket is not waterproof.

Types of Waterproof Electric Blankets

There are two types of electric blankets. They are;

  1. Under blanket
  2. Over blanket.

Under blankets act a bit like mattress toppers. It is also available in the market as an elastic band or attached sheet so that you can secure them to your bed.

On the other hand, over blankets are warmer than under blankets. You can use them on the sofa or even at your desk, making them a more versatile choice.

An electric blanket can also come with extra legs and different heat zones and heat settings.

The size of the blanket affects this. Most twin or top blankets have left and right zones, so settings can be customized if there are two people in a bed. Dual controls allow you to set settings at night without disturbing the other person. Therefore, it is the best choice for a home office worker.

With the advancement of technology, the products that come to the market for the convenience of the consumer are designed to avoid the problems that may arise. So, you might be skeptical that this might be a bit unsafe.
