Abstract: A heating vent conduit with a heater unit is disclosed, being primarily utilized to heat a room independently of other rooms. The heating vent conduit can be controlled a personal thermostat, which depending on the selected temperature will regulate a heating element within the heating vent conduit. The heating vent conduit is designed to be easily installed on existing ventilation systems by replacing the end boot at vent outlets, and will allow for individual preference and comfort by allowing independent room temperature, while lowering energy costs by reducing the main heater's workload.

Abstract: An infrared, room heater system for installation in a wall or on a floor. An electric fan assembly draws room air into a housing, then through three parallel, air transit channels where the air is heated by infrared radiation within and about a heat exchanger assembly, and then back out into the room. One or more ceramic heating elements attached to a first copper plate emit infrared radiation when electrically energized. The first copper plate lies adjacent to, but spaced away from, a second copper plate such that radiation emitted from the heating elements reflects back and forth between the plates. Room air passed between the copper plates is heated by heat radiation concentrated between the plates, thereby achieving both energy and space efficiency.

Abstract: A fan apparency arrangement for an appliance having a fan for moving air in an interior of the appliance, including a pipe disposed in the airflow path of the fan and having first and second ends; a heater disposed in the pipe, the heater being energized when the fan is turned on; and a thermal switch disposed in the pipe, the thermal switch being closer to the first end than the heater. The fan is operative in normal operation to move air in the pipe in a direction from the first end to the second end. The pipe is disposed so that when the fan fails to move air in the pipe after turned on, air heated up by the heater passes the thermal switch in a direction from the second end to the first end so that the thermal switch is activated to signal malfunction of the fan.

Abstract: Heating flange (1) for heating a flow of gas as it flows though a cross-section of flow (S), wherein the heating flange (1) is designed such that it can be inserted or interposed in an intake line (A) of an internal combustion engine and has at least one heat conductor (5) that extends through the cross-section of flow (S) from a mounting point (6a) to an immediately following further mounting point (6b) on the heating flange (1), as well as a retaining leg piece (2), which is provided with at least one of the mounting points (6a).

Abstract: An infrared, room heater system for installation in a wall or on a floor An electric fan assembly draws room air into a housing, through three parallel, air transit channels where the air is heated by infrared radiation within and about a heat exchanger assembly, and thence back out into the room One or more ceramic heating elements attached to a copper plate incorporate a resistive conductor that causes the elements to emit infrared radiation when electrically energized The first copper plate lies adjacent to, but spaced away from, a first heat insulated housing sidewall, thereby defining a first air transit channel The second air transit channel is defined by the space between the second copper plate and the second housing sidewall, and the third air transit channel is defined by the space between the two copper plates.

Abstract: The performance of a thermal insulation for a building surface 6, subject to a thermal gradient emitting from the building interior, is enhanced by a neutral thermal gradient. For this purpose an electrical heating element 1 is adapted to release very low Wattages of thermal energy and is contained within an inner layer 4 and an outer layer 5 of thermal insulation. Adjusting the thermal efficiency of the insulation layers controls the magnitude of the thermal energy required to maintain the temperature of the element 1 at the equivalent temperature level to the building interior. The element 1 may be provided with a moisture controller and discharge sizeable quantities of thermal energy to dry moisture from the thermal insulation materials of the assembly.

Abstract: A heating convection unit and a method of mounting the same, provided with an envelope having a front face, a rear face, a top, a bottom and peripheral side walls. The front face and the peripheral side walls define an inner enclosure. The unit is also provided with a medial shield having front face, a rear face, a top, a bottom and peripheral side walls. The medial shield is mounted within the inner enclosure defined by the envelope and spaced apart therefrom. The rear face and peripheral side walls of the medial shield and the front face and peripheral side walls of the envelope define a ventilation passage having top and bottom openings in communication with ambient air. The medial shield preferably has an intermediate opening communicating with the ventilation passage. The unit is also provided with a cover having a front face, a rear face, a top and a bottom. The cover is fixed over the medial shield. The cover has top and bottom openings in communication with the ambient air.

Abstract: A refrigerator having an apparatus for thawing frozen food includes food case mounted on the lower side of a partition for partitioning cooling compartments from each other, and a heater and a blowing device installed in the partition. The operating time of the heater and the blowing fan is counted in a timer. A user accommodates frozen food in the food case and sets a time for thawing by the timer. Then the frozen food is thawed by the operation of the heater and the blowing device. Thus, the frozen food can be thawed conveniently and rapidly.

Abstract: A cabin has a heating system integrated into one of its side walls. The heating system is arranged between an inner wall layer and an outer wall layer and has an ambient air channel with an inlet at the bottom and an outlet at the top. The heating system is designed to be space-savingly arranged within the cabin and to ensure a uniform heat distribution inside the cabin. The cabin thus has a large-surface radiant heating system built into the side walls and supplemented at its rear side relative to the outer wall layer by a reflecting layer that reflects the radiation of the radiant heating system into the cabin through the wooden inner layer.

Abstract: An assembly for efficiently supplying heated air to an enclosed area for drying the body of a person after bathing. The assembly has particular application for installation in an existing bathing area with a minimum of remodeling and with virtually all components being installed behind the walls and ceiling of the bathing area. The assembly includes blower means, duct means and heating means of special construction and location so as to more efficiently supply heated air to the bathing area.
