     DETAILED DESCRIPTION OF THE INVENTION 
     Referring now in detail to the drawings for the purpose of illustrating the present invention, a heating apparatus 10 as shown in FIG. 1, 2 and 3 comprises a water container 30, adapted to contain water 28, a burner 11 operatively associated with a fire box, disposed in the lower portion of the front side wall of the water container 30, a fireplace door 14 disposed at the middle portion of the front side wall of the water container 30, a water storage tank 22 extending from the top of the water container 30, a plurality of heating chamber 45 disposed in the upper area of the water container 30, and a chimney 41 disposed on the top of the water container 30. 
     The fire box disposed in the water container 30 includes a first floor 31 and a second floor 33 for burning either firewood or liquid fuel, respectively. The fire box is divided into the first and second floors 31 and 33 by a fireplace shelf 32. Also, the water container 30 includes liquid fuel storage tanks 44 disposed in the lower portion thereof, a plurality of upper and lower heat conduits 37 and 38 while communicate with the fire box for conveying heat from the fire box, and a fan 43 disposed at the upper rear side wall thereof (FIGS. 2 and 3). 
     The burner 11 mounted to the front side wall through a hinge 12 is provided with an electric wire 13 for igniting and the nozzle 17 is disposed in the second floor 33 of the fire box. The fire box door 14 which has a handle 15 is mounted to the front side wall through hinges 12 and includes a glass 16 having high temperature mechanical properties for viewing the heat conduits 38 (FIG. 1). The fire box shelf 32 contains a plurality of projecting members 49 holding the firewood 34. An air controlling member 48 is mounted to the lowest portion of the front side wall of the water container 30 through hinge 12, and includes a handle 50 and a gauge 51 for controlling the volume of fresh air to the fire boxes 31 and 33 by moving the gauge 51 in the direction indicated by arrow (D) and (E) as shown in FIG. 1. Also, the air controlling member 48 functions as door for cleaning out the ash 36 disposed below the fire boxes 31 and 33. 
     The lower heat conduits 38 disposed in the middle area of the water container 30 and the plurality of upper heat conduits 37 having a smaller diameter than that of the heat conduits 38 pass through the water container 30 and deliver the heat from the fire boxes 31 and 33 to the chimney 41, heating the water 28 in the water container 30 during the process. The lower heat conduits 38 communicate with the upper heat conduits 37 is a serpentine configuration. The plurality of heat chambers 45 containing a plurality of heat emitting members 46 are heated by the hot water circulating in the water container 30. The fan 43 inserted in a fan housing 21 blows air through chamber 42 in indirect heat exchange with the exhaust gas passing through conduits 38 and 37 into the plurality of heat chambers 45 and heat emitting members 46 for blowing hot air to the outside of the heating apparatus 10 through a plurality of louvers 18. The louvers 18 control the direction of the heat in any desired direction. 
     The water storage tank 22 comprises a bottle 23 which communicates with the water container 30 and a cap 24 having a handle 25, an extension member 27 (FIG. 3) and a plurality of raised portions for providing a space between the bottle 23 and the cap 24 to permit steam 29 to escape. Thus, the steam 29 from the water storage tank 22 can maintain the humidity in the room. When necessary, the water can be supplied through the top of storage tank 22. Also, since the open water storage tank 22 communicates with the water container 30, the water container 30 is prevented from exploding due to the accumulation of excess temperature or pressure in the container 30. 
     A controller 19 and a controlling panel 20 are disposed at the front portion in the top wall of the water container 30. The controller 19 controls the temperature in the water container 30 and actuates the fan 43 disposed in the fan housing 21 at a predetermined indoor temperature of the blowing chamber 45. Also, an on/off switch is disposed on the control panel 20 to actuate the burner 11 mounted to the front side wall of the heating apparatus 10. 
     The liquid fuel storage tanks 44 include feed inlets 40. Usually, the liquid fuel 39 is kerosene. The water container 30 is provided with a water draining member 47 for discharging the water in the container 30. 
     In the operation, after the water container 30 is filled with water as shown in FIG. 1 and pieces of firewood 34 are disposed on the plurality of the projecting member 49 of the fireplace shelf 32, the on/off switch disposed at the controlling panel 20 is actuated to ignite the nozzles 17 of the burner 11. 
     The burning firewood 34 heats the water in the water container 30, and the plurality of heat emitting members 46 disposed in the heat chambers 45 are heated by the heated water of the water container 30. At this time, the fan 43 disposed in the fan housing 21 is actuated to blow air through the blowing chamber 42. Accordingly, the hot air around the heat emitting members 46 is blown out in the direction indicated by an arrow (C) as shown in FIG. 3. The hot air is thus transferred to the room environment. The temperature in the indoors can be automatically controlled by the controller 19. By actuating the on/off switch disposed at the controlling panel 20, the burner can be continued or discontinued, as necessary, to burn the firewood 34. Also, the water inlet storage tank 22 is provided with a space so that it can prevent the heating apparatus 10 from exploding and add humidity to the room during the operation of the heating apparatus. 
     The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included in the scope of the following claims.
