Portable heating apparatus

Abstract

A portable apparatus for connecting to an external heating unit to safely heat an enclosed area such as a house under construction comprises an air transfer assembly for positioning in the house, said assembly having an air intake conduit for connecting to the external heating unit; a flue for carrying exhaust gases to an outside window of the house; and an electric fan for blowing air over the air intake conduit and through a vent in the air transfer assembly. The apparatus may further include a thermostat for shutting off the system at a preset temperature, a plurality of raised legs, a humidifier attachment, and a draft fan for an inlet end of the external heating unit to reduce backflow of exhaust gases when the external heating unit is cycled off and purge ignitable gases before the external heating unit cycles on.

1 . An apparatus suitable for connecting to a portable external heating unit for safely heating an enclosed area, said apparatus comprising: 
 (a) a air transfer assembly for positioning in the enclosed area, said assembly having a frame with at least one wheel for portability, an air intake connector for connecting to the external heating unit, a flue for carrying exhaust gases to an area outside the enclosed area, a heat transfer coil between the air intake connector and flue and an electric fan for blowing air over the heat transfer coil and through a vented opening in the air transfer assembly; and    (b) a thermostat for shutting off the apparatus at a preset temperature.    
   
   
       2 . The apparatus of  claim 2  which further includes an attachable draft fan for an inlet end of the external heating unit to reduce backflow of fumes when the external heating unit shuts off.  
   
   
       3 . The apparatus of  claim 2  which further includes an electrical outlet into which the external heating unit may be plugged.  
   
   
       4 . The apparatus of  claim 3 , wherein the air intake connection comprises an interconnecting sleeve for attachable connection to an outlet end of the external heating unit.  
   
   
       5 . The apparatus of  claim 3 , wherein the exhaust gas flue includes flexible tubing and an adjustable window cover for temporarily installing in an open window of the enclosed area.  
   
   
       6 . The apparatus of  claim 3  which further includes a humidifier.  
   
   
       7 . The apparatus of  claim 3 , wherein the air transfer assembly frame is raised on a plurality of legs at least two of which include the wheels.  
   
   
       8 . An apparatus for connecting to a portable external heating unit for safely heating a house on a temporary basis, said apparatus comprising: 
 (a) a heat transfer assembly, said assembly having an air intake connector, an interconnecting sleeve adaptor for attachable connection to an outlet end of the external heating unit, a flue for carrying exhaust gases to an outside window of the house, a heat transfer coil mounted between the air intake connector and flue, and an electric fan for blowing air over the heat transfer coil and through a vented opening in the air transfer assembly; and    (b) a thermostat for cycling on and off the apparatus at a preset temperature range.    
   
   
       9 . The apparatus of  claim 8  which further includes an electrical outlet into which the external heating unit may be plugged.  
   
   
       10 . The apparatus of  claim 9  which further includes an attachable draft fan for an inlet end of the external heating unit to purge ignitable gases before the external heating unit ignites.  
   
   
       11 . The apparatus of  claim 10  which further includes a humidifier.  
   
   
       12 . The apparatus of  claim 10  which further includes a plurality of legs at least two of which include wheels for transport.  
   
   
       13 . A mobile apparatus suitable for connecting to a portable external heating unit for heating a house under construction, said portable apparatus comprising: 
 (a) a heat transfer chamber for positioning adjacent an exterior window of the house, said chamber having an air intake connection for connecting to the external heating unit, a flue for connecting to a window adapter and carrying exhaust gases to an area outside the house, a heat transfer coil between the air intake connector and flue, and an electric fan for blowing air over the air intake conduit and through a vented opening in the air transfer chamber; and    (b) a thermostat for shutting off the apparatus at a preset temperature.    
   
   
       14 . The mobile apparatus of  claim 13  further comprising a draft fan attachment to an inlet end of the external heating unit for reducing backflow of exhaust gases when the external heating unit is cycled off and purging ignitable gases before the external heating unit cycles on.  
   
   
       15 . The mobile apparatus of  claim 14  wherein the air intake connector is attachably connected by a sleeve adaptor for fitting to an outlet end of the external heating unit.  
   
   
       16 . The mobile apparatus of  claim 15  wherein the heat transfer chamber further comprises a humidifier attachment.  
   
   
       17 . The portable apparatus of  claim 15  wherein the air transfer chamber assembly has a frame raised on a plurality of legs at least two of which include wheels for assembly transport.
