Abstract: This is a new fireplace, which is either constructed in place or is totally prefabricated in advance and placed within a building where desired. The fireplace is particularly characterized by a pair of overlapping hollow members placed within the throat of the fireplace above the combustion chamber, wherein one of the hollow chambers receives cool air which is heated and then expelled for use, and a second chamber in which an arrangement of tubular members is embedded carrying water into the tubular arrangement for purposes of heating and then bringing the water out of the fireplace. A humidifying liquid is presented into the first chamber and an adjustment for changing the size of the throat is also provided. A method of constructing and assembling the fireplace, or combustion apparatus, in such a manner that it can be prefabricated away from the site of installation.

Abstract: This is a new fireplace, which is either constructed in place or is totally prefabricated in advance and placed within a building where desired. The fireplace is particularly characterized by a pair of overlapping hollow members placed within the throat of the fireplace above the combustion chamber, which hollow members are interconnected on each side to ducts, one side of which receives cool air and the other side of which expels hot air. Blowers are provided in the duct lines in order to force the hot air into the areas desired for maximum heating.
