Heaters – We All Took Them For Granted
Wherever you live, chances are high that you will need a heater of some sort in your life. Since early mankind discovered fire, heaters have been used for warmth, cooking, and protection from potential enemies. The Encarta dictionary defines a heater as “a device that uses some kind of fuel to produce heat in order to make something warm or hot, especially a device to heat the air in a room or vehicle.” However, heaters have many other usages as well; unless you eat only raw food, including meat, you will need a heater to cook with; a stove, oven and various electrical appliances that cook your food. You need to heat your bath or shower water when you wish to shower; this not only provides personal comfort, but aids in killing harmful bacteria on your skin. Even if you live in the hot and desert areas of the world, it’s well-known that deserts cool down dramatically at when night comes; you’ll find yourself shivering without a heater. Heat also plays a crucial industrial role by liquefying metals so they can be formed into tools, appliances, automobiles, etc. Many chemical reactions such as gasoline also require heaters that produce energy.
Just How Do Heaters Work?
Heating processes are designed to produce and stabilize thermal conditions within buildings, for industrial use, and for comfort. Heaters cause a rise in temperature via electricity, gas, or solar energy. Thus, if you have stove and oven in your home, it could be heated by electrical current or by natural gas. Other forms of fuel such as propane, gasoline and kerosene are also used. All these substances form the chemical reaction of heat production; this is good if you want to cook your food or warm up a room. It can be disastrous if gasoline and other flammables are over-exposed to a heat source that subsequently causes an explosion of flames and intense heat, destroying structures and life alike.
Heaters, therefore, must be used cautiously so that they perform their desired purpose without causing destruction. Any heat source carelessly used or unsupervised can mean unprecedented disaster that could result in loss of human live.
Extreme cold can causes illness, injury and even death. Inhabitants of northern or southern arctic regions of the world employ some sort of heater to help them survive the long, dark, and cold winters. These devises range from simple open fires to built-in contain fireplaces. Similarly, livestock just like human beings must also be kept warm during winter. Many species of animals have cold-resistant fur or feathers, but domesticated animals like cows, sheep, hogs and horses will need a heating device in their stables or barns to keep them warm. Losing livestock to extreme cold weather can mean economic devastation to farmers and ranchers.
Heat is a life-giving necessity. Excesses in temperature (heat or cold) are responsible for loss of life as well as personal discomfort. Heaters have indeed become a necessities of life.
