Heat Exchanger

A heat exchanger is a device that transfers heat from one source to another. For example, there is a heat exchanger in your furnace – the propane flame and combustion products are contained inside the heat exchanger that is sealed from the inside area. Inside air is blown over the surface of the exchanger, where it is warmed and the blown through the ducting system for room heating. The combustion gases are vented to the outside air.
