Pocket heaters come in handy on many occasions. Widely used by hunters and outdoor enthusiasts, they also work well in emergency situations. Because they are so affordable, there really is no reason not to have one on hand, especially if you spend a lot of time outdoors.
The little warmers come in two varieties, refillable and disposable. The choice is up to you. At the time of this writing, prices range from approximately nine dollars for a pack of 10 disposable heaters to $60 for a deluxe model with electric ignition.
The concept of this heater is not a new one. It was discovered in 1923 by a Japanese inventor (Niichi Matoba) who obtained a patent for the applied principle of oxidation reaction, which ultimately produces heat by way of platinum catalysis. Although there are several brands available on the market today, one of the most popular (the Butterfly) is still produced by Matoba’s company.
The heaters are environmentally friendly. They produce no pollution or waste and light very quickly. Believe it or not, they are an adequate personal heat source, even in minus 40 degree F temperatures. It should be noted that refillable heaters produce roughly 5 times more heat than disposable versions. Once you purchase one of these pocket warmers, the only thing that will ever need to be replaced is the burner and the fuel used to operate them.
Using pocket heaters is easy. To fill one of them, first remove the top cover and then the burner. Place the filling cup into the opening in the fuel tank. Proceed to fill the cup with fuel, and then turn the cup, allowing the fuel to run into the heater. Remove the cup and turn the heater upside down and squeeze gently to discharge any extra liquid. Finally, replace the burner.
To light the burner, light the element with a lighter or match for no more than 10 seconds. Replace the cover. Be advised that after you light the burner, you will NOT see a flame. Appropriate fuels for this type of burner include pure white gas, fluid benzene and lighter fluid.
Pocket warmers can be placed in a pocket, a pouch around your neck, or in a bed. The disposable variety is ideal for placing in socks or gloves. This tiny heater makes a wonderful gift for anyone who gets cold easily or who is trying to save some money on heating costs. Chances are it is a product they would never think of buying for themselves.
