Abstract
A heat exchanger for use with a source of heat in the form of a burner arrangement. The heat exchanger includes a relatively high flow resistance main passage for collecting combustion products from directly above the burner and a low flow resistance secondary passage opening forwardly of the main passage inlet and conveying any combustion products not collected by the main passage relatively directly to the flue. Flue downdraft principally affects flow in the secondary passage. The main passage may include a plurality of chambers to increase the heat exchange surface area. Water condensing in the main passage can be collected and drained to an evaporator rear the burner.
