Heat exchangers are designed to transfer heat more efficiently from one medium to another. Typically, heat exchangers use fluids to store heat but recently, with the creation of more advanced technology; gases can now be used to transfer heat. Heat transfer can take the form of absorption or dissipation. Unknown to many, heat exchangers are found in everyday equipment • Boilers, furnaces even refrigerators and air conditioners!

Most people think that heat exchangers are used only in industrial process, but the truth is, it is now used in the household to transfer heat more efficiently. This sentence has huge implications • With energy bills going up, heat exchangers can help store heat so that you can now cut down on your heating or cooling bills. Heat exchangers recover wasted heat to make it useful again.
