BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention relates to a wood burning stove for heating water and 
more particularly pertains to a wood burning stove capable of heating both 
radiator water and potable water as well as the room in which it is 
located. 
2. Description of the Prior Art 
The use of wood burning stoves is known in the prior art. More 
specifically, wood burning stoves heretofore devised and utilized for the 
purpose of heating water, air and the like are known to consist basically 
of familiar, expected and obvious structural configurations, 
notwithstanding the myriad of designs encompassed by the crowded prior art 
which have been developed for the fulfillment of countless objectives and 
requirements. 
Prior art efforts for improving stoves for heating water and additional 
functions are disclosed in the prior art. Note for example, U.S. Pat. Nos. 
5,123,360 to Burke and 5,139,082 to Timpano which disclose fuel burning 
stoves with air flow means for increasing efficiency. In addition, U.S. 
Pat. Nos. 4,250,864 to Bergman and 4,534,319 to Manno disclose fuel 
burning stoves wherein the fuel is supported on tubes as for conveying 
water. The Manno device also includes a heat exchanger connected to a 
domestic hot water supply. Lastly, additional patents of interest are 
disclosed by Walsh in U.S. Pat. No. 4,261,329 and by Labigner in U.S. Pat. 
No. 4,467,959. The Walsh disclosure relates to a modular solar panel 
energy system while Labigner teaches mechanisms adjacent the flue of a 
stove for providing heat to a room in which it is located. 
In this respect, the wood burning stove for heating water according to the 
present invention substantially departs from the conventional concepts and 
designs of the prior art, and in so doing provides an apparatus primarily 
developed for the purpose of heating radiator water, potable water, air 
and the like. 
Therefore, it can be appreciated that there exists a continuing need for 
new and improved wood burning stove for heating water. In this regard, the 
present invention substantially fulfills this need.

DESCRIPTION OF THE PREFERRED EMBODIMENT 
With reference now to the drawings, and in particular to FIG. 1 thereof, a 
new and improved wood burning stove for heating radiator water embodying 
the principles and concepts of the present invention and generally 
designated by the reference numeral 10 will be described. 
More specifically, it will be noted that the stove 10 is for the generation 
of heat from the burning of wood for heating water and for heating the 
room in which it is located. The stove comprises a drum 12 which has 
cylindrical side walls 14 oriented and supported about a horizontal axis. 
Support legs 16 depend therefrom. Circular end walls 18 and 20 are 
provided. A door 22 is formed in the upper half of one end wall 18 for the 
introduction of scrap wood to be burned onto the horizontal pipes. A tray 
24 is located at a lower extent of the drum for supporting the ashes. A 
second door 26 is formed in the lower half of the end wall 18 beneath the 
first door 22. The second door 26 is for the removal of ashes from the 
tray 24. Note FIGS. 2 and 3. 
An array of tubes is provided for conveying water to be heated. Such tubes 
include a water input tube 28 and a water output tube 30. These tubes 
extend to radiators exterior of the drum. Such tubes extend through the 
end wall 20 opposite from the door 22. 
The tubes interior of the drum include a rectangular array 34 in a 
horizontal configuration adjacent to the widest part of the drum. The 
rectangular array 34 is coupled to the water input tube 28. The tubes 
interior of the drum also including an array of semicircular tubes 36 
extending upwardly from the rectangular array in parallel alignment about 
the axis of the drum 12. The tubes interior of the drum also including a 
linear output tube 38. The output tube is parallel with the axis of the 
drum at the topmost part of the semicircular tubes. The output tube 34 
functions to discharge the heated water from the drum. 
Coupled to an upper extent of the drum 12 is a chimney 42. The chimney 42 
is coupled to the drum for conveying away smoke from interior of the drum. 
An air input tube 46 is located at one side of the drum. The tube is 
provided with a damper 48 interiorly thereof. A thermostat 50 is coupled 
to the damper for controlling the damper. The thermostat functions for 
determining the extent of opening up a damper allowing air to the drum 12 
to determine the heat output of the stove and heated water. 
In addition to heating water for radiators which heat space in a house, the 
stove 10 of the present invention also can heat the potable water of the 
house. A copper domestic cold water inlet line 54 of copper tubing is 
located adjacent to water input tube 28 and extends therethrough. Inlet 
line 54 extends within tube 28 horizontally along the length of the 
horizontal array 34, up the endmost semicircular tube 36, back 
horizontally along output tube 38 and then through output tube 30. Where 
it emerges as the domestic hot water is outlet 60. The copper line 54, 56, 
58, 60 heats the potable water flowing therethrough by the heat of the 
fire in the furnace as well as by being in heat exchanging relationship 
with the radiator water flowing through the array of tubes from the input 
tube 28 to the output tube 30. The copper tubing is of sufficiently small 
size so as to allow radiator water to flow over and around the copper 
tubing for maximum heat transfer while achieving its objective of heating 
both radiator water and potable water as well as heating the air in the 
room where the stove is located. 
As to the manner of usage and operation of the present invention, the same 
should be apparent from the above description. Accordingly, no further 
discussion relating to the manner of usage and operation will be provided. 
With respect to the above description then, it is to be realized that the 
optimum dimensional relationships for the parts of the invention, to 
include variations in size, materials, shape, form, function and manner of 
operation, assembly and use, are deemed readily apparent and obvious to 
one skilled in the art, and all equivalent relationships to those 
illustrated in the drawings and described in the specification are 
intended to be encompassed by the present invention. 
Therefore, the foregoing is considered as illustrative only of the 
principles of the invention. Further, since numerous modifications and 
changes will readily occur to those skilled in the art, it is not desired 
to limit the invention to the exact construction and operation shown and 
described, and accordingly, all suitable modifications and equivalents may 
be resorted to, falling within the scope of the invention.
