Design:
Early models of electric blankets were large, bulky, and difficult to use. Modern electric blankets have overcome some of these restrictions. They are constructed of thick, acrylic polyester, which is lightweight. Heating is by internal heating wire under the control of an analog-based solid-state controller. Electric blankets can have up to 9 heat settings to cater to varied comfort levels and an automated shut-off function after a certain period. Once the blanket is sufficiently heated up, the heat is distributed evenly throughout the blanket.
Energy savings:
Electric blankets consume much less electricity as compared to other heating systems like space heaters, radiators, etc. Proper usage of the blankets can also go a long way towards reducing energy consumption. The most energy-efficient way to use an electric blanket is to switch it on to its highest setting and warm the bed. Once the bed is sufficiently warm, the blanket should be switched off. Using an electric blanket allows you to turn down the thermostat and thereby save on heating costs.
Precautions during usage:
Electric blankets should be used carefully. While purchasing a blanket, ensure it meets all standards of quality and safety and follow the manufacturer's instructions. Never fold blankets as this can damage their wiring. For storage purposes, rolling up a blanket is sufficient. Blankets may also be tied to the bed to minimize damage due to creasing.
Electric blankets require replacement every ten years. Blankets may also need to be replaced before ten years if they show signs of wear and tear such as scorch marks, exposed wires, creases or folds, damp or soiled areas, frayed fabric, and loose connections. If a blanket gets wet, avoid using it till it dries and do not dry the blanket by switching it on.
