  • Radiant space heater for residential use
    Patent number: 5628303
    Abstract: A compact gas-fired radiant space heater is adapted for residential use, having an output in the 20k BTU to 40k BTU/hr range and exterior dimensions small enough to allow it to be installed in a standard two foot by four foot suspended ceiling opening. A radiator tube having a total length of approximately 15 feet is bent into a serpentine shape, and combustion control components are housed within a plenum chamber supplying combustion air to the tube, both the tube and the chamber being encircled by a frame that fits within the two foot by four foot opening. The combustion control components are attached to a chassis plate whereby the components are removable from the plenum chamber as a unit to enhance serviceability of the heater. A burner venturi of novel configuration produces a flame that is less than four feet long yet which is relatively quiet.
