Abstract
A fireplace heat exchanger apparatus and method utilizes a tubular grate for holding fuel to be burned having a bottom portion for collecting a liquid such that the liquid will be vaporized by the heat from the fuel burned in the grate and carried into a space to be heated by air forced through the tubular grate to substantially increase the amount of heat obtained from burning of fuel.
