Claims.
This invention relates to air heating systems for buildings having one or several or all of the rooms substantially covered by an attic which is sealed at its top and sides to the exterior, the
5 building preferably being a small, single-story residence with its main rooms on the ground floor. The air heater of the system is preferably located in the attic but may merely open into the interior thereof, and likewise there is preferably located in the attic the means, such as a fan, for maintaining a diierence of air pressure in the interiors of the room or roomsv and the attic whereby a circulation of heated air is maintained therebetween. The primary object of the invention is to maintain a circulation of heated air in a build ing in such manner as will provide an inexpensive and eiicient heatingsystem by reason of the circulation not only in the room or rooms xwhich are generally occupied but also in the attic which then acts as an eective heat insulator between the ceiling of the room or rooms and the exterior of the building.
Another object is to utilize the attic as a large and usually unobstructed chamber or duct of the heating system in which is contained at least a portion, and preferably all, of a main duct, for conducting the heated air between the heater and the branch ducts for the rooms, the attic `being capable also of containing if desired the air heater and the fan so that loss of heat from the heating system. is conserved and the loss from the building minimized, and so that the cost of construction of the building is reduced. Other objects and advantages will appear from the following description of the preferred arrangement for a single-story residence as an example, and from the accompanying drawings thereof in which Fig. 1 is an elevational cross section of a building in which, as an example, the attic is arranged over all the rooms on the ground floor andthe air heater and a fan are located in the attic; Fig. 2 is a plan View of the ground iioor thereof; 45V and Fig. 3 is a plan View of the attic thereof. Referring to the drawing, reference numeral I represents end walls of suitable construction, 2 represents interconnected rooms on the ground iioor, and 3 represents the attic arranged over the ceilings 4 and sealed to the exterior by the roof 5 and the upper parts of the side and end walls I by the complete absence of openings therethrough and suitable wall boards secured thereto. The gas-red air heater 6 with an air linlet 'I, having a damper if desired, is located in the attic to preclude the necessity for a basementor the use therefor of a portion of the ground floor and to permit a short chimney or ue 8, with a damper if desired, for the discharge of products of combustion from the furnace of the heater. A fan 9, located alongside the heater ii, is connected to the air outlet theren of by the air duct I@ and also to a main air duct il which has branches I2 extending to registers I3 in the lower parts of the rooms 2. Other air ducts Ill extend through the ceilings Yi of the rooms to connect the interiors of the rooms and attic. A trap door I5 or the like provides access to the attic.
When the outdoor temperature is suiciently low, gas preferably but if desired electricity or other kind of fuel preferably requiring no pump or cartage for supplying it to the heater and preferably adapted to the use of suitable temperature controlling `devices in the rooms, is.
utilized for heating the air n the well known manner. The fan 9 is operated, preferably electrically, to draw air from the interior of the attic 3 into the inlet 'I of the heater E where it is heated to a suitable temperature and if desired also cleansed, puried and humidied. The heated air is then forced by the fan 9 through the main air duct il extending within the attic, and thence through the branched air ducts I2 and registers I3. The resulting reduction of air pressure in the attic and the increase of air pressure in the rooms vassist the natural tend# ency of the heated air to rise-through the rooms from the registers to the ceilings and to pass through the air ducts ill back into the interior of the attic from whence it is again drawn into the heater for reheating. In this circulation, the heated air is mixed with accretions of fresh air naturally leaking through windows and doors of the rooms, thereby maintaining the air within the rooms and attic at a suiiicient degreevof purity.
The heated air circulating in the attic acts as an eiective insulator for the ceilings il against 'the colder temperature on the'outside of the roof 5 and the upper parts of the end walls and the `side walls I. Furthermore; as a result of the absence of loss of any substantial amount of heated air from the rooms and attic to the eX- terior of the building, and also since the heat radiated and conducted from the heater E, the interior portion of the chimney or liue 8 and the main air duct II heats the. air in the attic, the .amount of gas or other heating medium consumed by the heater in maintaining the desired temperature throughout the building is reduced.
' Furthermore, by locating the heater and fan in the attic, no basement or extension is required and the cost of constructing the building is reduced thereby and also by the possibility of a shorter chimney or iiue 8. In effect the attic constitutes a sealed chamber or duct from which -the air to be heated is drawn and in which is arranged the main supply yduct for the heated air for the rooms below. By omitting partitions and other obstructions in the attic as shown, the circulation of the heated air in the rooms and attic is enhanced and the volume of heated air forming the source of supply for circulation therein and for the insulation of the ceilings 4, is increased. The air for combustion of the gas in the furnace of the heater may be heated air taken from the interior of the attic or air taken from outdoors through a duct.
If desired, the air heater or the fan or both may be located elsewhere than in the attic, in which case the heater would merely have an opening into the interior of the attic and the main air duct Il would merely have a portion in the attic. Also, if desired, the air heater may be located in the attic but enclosed therein by a fire-resistive partition or door, in which case the heater would likewise have an air opening, whether inlet or outlet, extending into the interior of the attic for circulation of the heated air. Furthermore, in any of these arrangements, the heating system could be arranged to discharge the heated air from the heater into the interior of the attic and withdraw it from the rooms through the main duct Il. Still other modifications may be made without departing from the spirit of the invention as defined 1n the appended claims.

air duct connected to the heater and extending within the attic, a second air duct connecting the rst one to the interior of the room, and a third air duct connecting the interiors of the room and attic whereby al path of circulation for the heated air is provided from the heater to the room to the sealed attic and to the heater from the attic for reheating and recirculation thereof in an eicient manner, said sealed attic providing an effective heat insulator between the ceiling of the room and the exterior of the building, and means for maintaining a diiference of air pressure between the interiors of the room and attic whereby the heated air is maintained in circulation in said path.
