How an Electric Cup Warmer Works

• Electric cup warmers are coaster-like devices that keep mugs and other heat-conductive cups warm, no matter how long they sit at a desk or on a counter. Office workers commonly use mug warmers to maintain a constant temperature for a cup of coffee or tea without needing to refill the cup with warm liquid. Electric cup warmers can also help keep soups and broths warm. Many mug warmers have a standard electrical plug, but other designs allow the mug warmer to be powered by plugging it into a computer's USB port.
• A mug warmer does not actually heat up a liquid; it simply helps keep an already hot liquid warm, much like a coffeepot keeps its contents heated indefinitely. Once a drink reaches the preset temperature based on the heat of the warmer, it will not decrease in temperature no matter how long it sits.
• Most cup warmers use small heating coils to heat the surface. A heating coil is often cylinder-shaped and built into the warmer under the surface. Depending on the brand, some mug warmers may use voltage regulators as the main heating element. The regulators are soldered to the inside of the warmer, and when the mug warmer is turned on, electricity flows through the coil or regulators to the surface of the warmer.
• The electric cup warmer works on the scientific principles of heat transfer. As the warmer heats up, the molecules gain kinetic energy. When someone places a cup on the warmer the molecular energy from the device transfers to the mug. As the mug's molecular energy increases, it transfers the heat to the liquid in the cup. This heat transfer process keeps the liquid in the cup warm.

How to Keep Coffee Warmer for Longer?

Coffee just isn't the same when it's lukewarm. Coffee is best when it is either very hot or over ice, not tepid. Keeping coffee warmer longer requires just a little innovation and thinking ahead. Keep your coffee warmer by making it hotter initially, using a different way to prepare the coffee, using an electric coffee warmer or using a glass-lined thermos. Using a microwave to reheat coffee changes its taste and composition. Avoid having to use a microwave by trying these tips.

• Make it Hotter
• Make your coffee hotter initially to ensure it stays hot longer in the day. If you're ordering it from a coffee shop, ask the barista to prepare the coffee drink extra hot.
• Turn the temperature up on your current coffee pot. Most coffee pots come with a temperature control that can make the water hotter or cooler depending on your preference.
• Use hot water in your drip coffee maker instead of cold water. Although the manufacturer encourages the consumer to only add cold water, hot water can be used to make the coffee hotter when it is brewed. Check with your warranty for your specific coffee maker to ensure this won't void the warranty.
• Brew With a French Press
• Brew your coffee with a French press instead of a traditional drip coffee brewer. A French press allows you to add your own water at any temperature to make it as hot as you like.
• Pull the plunger out from the press. Add 3 tablespoons of ground coffee. Heat 3 cups of water on the stove to the temperature you want.
• Pour the hot water into the plunger and let it steep for 4 minutes. Press the plunger down to strain the coffee from the water.
• Pour and prepare your coffee the way you like it.
• Use a Glass-Lined Thermos
• Use a glass-lined thermos to keep coffee hot for 3 to 4 hours.
• Avoid using any other type of thermos as they will not hold the heat as long.
• Pour boiling water into the glass-lined thermos before using for coffee. Let it sit for 5 minutes.
• Dump out the hot water and add hot coffee immediately. Screw the top on and keep it secure until you're ready to drink.
• Use an Electric Coffee Warmer

• Purchase an electric coffee warmer available at retailers such as Target or Office Depot .
• Plug it in where you will be spending most of your time drinking your coffee and wait for the heating element to warm up.
• Place your ceramic mug on the warmer. Do not use paper or Styrofoam with an electric coffee warmer.
