A modular furnace for adaptation to a conventional domestic heating system includes a firebox which is enclosed on both sides, the top and the bottom. The front portion of the firebox includes an access door for introduction of the combustible fuel onto a grate, and the back of the firebox includes a first opening for an air inlet tube and a second opening for air flow beneath the grate. The inlet tube extends above the grate and provides a single air outlet adjacent the front portion. Surrounding a majority of the firebox is an external housing and extending up the sides and front portion of the firebox between the firebox and the housing are a plurality of air flow passageways. These passageways extend across a V-shaped finned heat exchange plate which comprises the top of the firebox. Heat from the heat exchange plate is convected to circulating air which then exits from the furnace by means of a conduit which is suitable for adaptation to the main heating duct of a conventional domestic heating system. |
