Abstract
A heat exchange device is disclosed herein to be used in conjunction with a standard fireplace. The heat exchange device is made from a continuous tube fabricated into loops that surround the burning fuel. The ambient room air, introduced through an opening for air entry into the tube, is blown through the internal lumen of the tube fabricated into loops, the external surfaces of which are in direct contact with burning fuel and flame. The air passing through the internal lumen of the tube fabricated into loops is heated to a high temperature by the burning fuel and flame.
