Introduction
Heating pads serve as a safe and affordable means of staying warm during the cold months. Since their invention, heating pads have been manufactured to meet the needs of different situations. Each of these types of heating pads works in different ways. These various types can range in both size and function, serving to warm different types of body parts for different reasons.
Chemical Heating Pads
Chemical heating pads utilize a heat recess fueled by chemicals. One of the most implemented types of chemical heating pads is sodium-acetate heating pads. As the name entails, this heating pad uses mixtures of sodium acetate to heat the pad. These chemicals crystallize when placed against the metal disc inside the pad.
Because this solution is so dense in its chemical properties, the crystallization does not happen instantaneously over the entire pad. The result is a pad that can heat for a long period of time in relation to its size. Once a section's heating capabilities are exhausted, it will solidify. Even after the reaction process is complete, the crystallized section will continue to retain heat. These pads can be placed in boiling water to recharge them.
Electrical Heating Pads
Electrical heating pads are reusable heating apparatuses that work through plugging them into a standard electrical outlet. These are one of the most common household types of heating pads. The physical structure of a heating pad consists of three essential parts. These electrical heating pads often contain controls to adjust the levels of heat at which they run. That controller runs inside the blanket and fuels insulated wires to produce heat through electricity, which comes from an electrical cord extending from the bedside control into a power outlet. For safety purposes, these electrical wires are insulated by a unique type of plastic. In order to best release and retain adequate amounts of heat, the outside blanket is usually constructed of a mixture of polyester and acrylic fabric.
