Heating system with adjustable louver

Abstract

A heating system including at least one louver coupled with the housing of a heater including a blade and end caps on the blade for holding each louver in a fixed position during operation of the heater assembly, but also releasing the louver for adjustment in positioning relative to the axis of rotation of the louver to change air flow direction or other characteristics as desired.

What is claimed is: 
     
         1 . A heating system comprising:
 a housing through which air flows through a heating element from an inlet to an outlet;   at least one elongated louver having a first end and a second end and a central axis of rotation;   an element at each end of said louver to engage the housing, with a first element engaging said housing in a fixed position and also adjustable to other fixed positions and a second element engaging said housing in a resilient position to release said first element to be adjusted to a second fixed position;   a blower for continuously forcing air through said compartment; and   a heating element.   
     
     
         2 . A heating system as set forth in  claim 1  further comprising multiple louvers. 
     
     
         3 . A demand radiant heating system as set forth in  claim 1  wherein said louvers can be adjusted a various intervals by a disengagement and re-engagement of toothed gears disposed in said first element. 
     
     
         4 . A demand radiant heating system as set forth in  claim 1  including means disposed adjacent said burner for igniting an air/fuel mixture in said burner and for sensing a predetermined temperature of said burner. 
     
     
         5 . A demand radiant heating system as set forth in  claim 6  wherein said igniting and sensing means comprises a glow bar ignitor. 
     
     
         6 . A louver for a heating system comprising: an elongated blade having a first end and a second end;
 a housing in which the louver is disposed, the housing defining a compartment into and out of which air flows and includes an element for heating the air passing by the heating element;   a fan continuously forcing air into said compartment;   said louver including elements to attach the first and the second end to the housing, comprising caps at each of the louver;   One cap having an adjustable element relative to the housing and the other cap having a releasable element relative to the housing to permit the adjustable element to move from a first fixed position to a second fixed position.   
     
     
         7 . An invention as set forth in  claim 6  further comprising that multiple louvers are engaged with the housing. 
     
     
         8 . A heating system comprising:
 A housing having a heating element, a fan to continuously blow air over the heating element, and an outlet for the heated air;   At least one louver at the outlet of the housing, said louver having an axis of rotation and a mechanism to adjust the louver to alter the direction of air flow from the heating system flowing past the louver by rotation around the axis of rotation, comprising engagement elements at each end of the louver, with a first element engaging at least a portion of the housing and a second element engaging at least a portion of the housing; and   one of said elements moveable ; and   said first element having a lock to engage at least a portion of the housing in place and release to permit the second element to rotate and return the louver to lock engagement when the release is no longer engaged.
