ABSTRACT:
A fireplace heat exchanger comprises a plurality of laterally spaced, C-shaped heat transfer tubes, each having a mounting plate connected at its lower end. A header extends along the tube lower ends to flow air therethrough, and removable fasteners individually connect each mounting plate to the header. A bracket interconnects the outer ends of the tubes, such that a damaged tube can be easily replaced by disassembling the bracket, removing the fasteners from the damaged tube, and detaching the mounting plate. The heat exchanger also includes a humidifier, comprising a water carrying conduit which extends through one of the tubes. Water droplets are slowly metered from the conduit onto a hot upper surface of the tube, and vaporize substantially instantaneously upon impingement to therewith mix with and humidify the heated air flowing through the tube.
