2 Claims. (01. 237-49) This invention relates particularly to a system for heating homes, apartments and the like;
Cine ofthe objects of my invention is to provide a radiant heating systemthat can be applied to practically any type of existing home without any alterations to" said home. This'takes in a twostory home with basement and attic space; a onestory home with basement; a one-story home withoutia basement, but with an attic space.
A'further object isto do away with the necessityfor all firestopsas shown in my application No'. 6'1,840, filed December 29, 1948, now aban doned or in-my application Serial No. 85,949, filed April 7', I949. I
A further object is to provide a means of heating certain rooms, such asbathrooms, to a higher temperature than other rooms.
*A further object is to provide a warm air radiant-heating system that is simple, safe and eifective, with no danger of developing air temperatures that will set the house on fire.
A-= further object is to provide a warm air radiant heating system that uses the structure of the building, "(i.*e., wood joists, etc.) for conducting the air and. for storing heat, that is simple, low in cost, safe and efiective.

Figure 7 shows an enlarged sectional view of the second floor ceiling, showing the arrangement of insulation I have found desirable at this point.
Referring to the drawings, (see Figure 1), the letters A, B, C and D indicate the basement, first floor, second floor and attic, respectively.
The numeral 1 indicates a steam boiler. 2 is a steam coil which is connected to the boiler I by the steam pipe 3 and the return pipe 4. 5 is a between all joists.

Air dampers 20 are located in-the return air ducts IQ-near-the'pQints where these ducts spill the airinto du'ct'I3L See Figures 1, 2 and 4. It will be noted that the top of air duct I9 is covered,under joists H, leaving onlya narrow slot 21, seeFIgure- 4.:. The slots 212 are for thepurpose of getting. even-distribution of the heated air to all spaces If I did not provide these narrow slots 2| .asshown, I would get little or no heat into the joist. spaces that'arelocated away. fromthe heat coil 2.. The air dampers 20 may be used to regulate the heat in the four different sections of the building.
It will be noted that I provide an opening 22 (see Figure 6) which connects to the heated air supply. By so doing, hot air will enter into the space 23 between the wall studs and will furnish additional radiant heat to the room or rooms adjacent to said wall. This may, for example, be a bathroom. If it is desirable to heat only one side of the wall, insulation 24 can be used so that practically all of the heat from the wall will be rediated one way. I provide stops 25 so as to limit the wall area I desire to heat. This makes a convenient and simple method of getting a bathroom five or six degrees warmer than other rooms.
The numeral 26'indicates the basement walls, 21 the basement floor, 28 an I beam for supporting the basement ceiling joists H.
The housing 21A encloses the blower, which blower discharges air into the housing 9, which air passes upward through the heat coil 2 and into the duct I and from the duct I0 between all joist spaces 29, through th slot openings 2| and into the return ducts I9 and space I3 back to the suction side of the blower 8.
The numeral 30 is a toilet. 3| is a bathtub. 32 is the ceiling of the first floor, 33 is the floor of the second floor, 34 indicates the first fioor ceiling joists. 35 is the ceiling of the second floor. 36 indicates the second floor ceiling joist, IBA indicates insulation located near the top of the second floor ceiling joists, 38 is a paper board which covers and seals the top of joists 36. 39 is insulation on top of the paper board 33.
The method of heating the ceiling 35 of the second floor is identical to heating the floor I of the first floor. I use a blower 8A, a heat coil 2A which is connected to the boiler I by the pipe 3A and the return pipe 4A. An air relief valve 5A is connected to the return pipe 4A. The blower 8A discharges air through the heat coil 2A and then into the heat duct I HA. I use the same type of return air ducts which connect to the space I3A which space connects with the air intake of blower 8A. The housing 21A covers the blower 8A. I use a similar insulation I4A near th ceiling 35 under the duct IDA. I use insulation I 6A to reflect the heat between joists 36 to ceiling 35. All of the parts used above the ceiling 35 of the second floor are, generally speaking, the same and function the same as similar parts used to heat the floor of the first floor, therefore I feel that my general description of the function and operation of parts for heating the floor of the first floor should serve and apply to heating the ceiling of the second floor and that no further description is necessary.
The numeral 40 indicates the side walls of the building, 4| is the roof.
1. A heating system adapted for installation in a standard building construction, which includes floor and ceiling walls supported by spaced transverse joists forming air passages extending to an outer wall of thebuilding, including in combination therewith a heat exchanger located on one side of said floor-ceiling, a housing for said heat exchanger in open communication with a centrally located portion of one of said walls, a plurality of air inlet ducts extending in difi'erent directions away from and in closed communication with said housing and extending transversely of the joists and in communication with the air passages therebetween, a blower in said housing for forcing a heated air stream in contact with said heat exchanger and through said duct and along said air passages, a first return duct at the opposite end of said joists in proximity to a building wall extending transversely of said joists and in communication with the discharge end of the air passages therebetween at the opposite ends from said inlet ducts, a second return duct in communication with said first return duct for returning the air stream to the suction side of said blower, and damper means located between said return ducts for controlling the flow of the air stream to selected areas of the floor and ceiling walls.
, cludesp in combination, first and second walls horizontally disposed in parallel spaced relationship, vertical joists arranged in spaced relationship between said walls and forming therewith a plurality of closed air passages extending to opposite exterior walls of the building, a plurality of air inlet ducts extending in different directions in transvers communication with said air passages and opening into a housing which is centrally located relative to and in open communication with one of said walls, a heat exchanger in said housing in closed communication with said ducts, a blower in said housing for forcing a heated air stream through said ducts and in different directions along said air passages to opposit vertical walls of the building, a first return duct at the opposite end of said joists from said inlet ducts and in proximity to said vertical walls and extending transversely of said joists and in communication withthe discharge end of the air passages therebetween and a second return duct in communication with said first duct for returning the air stream to the suction side of said blower.
