Heat Recovery Atmospheric-Pressure Vat

Abstract

A hydronic heating system. A vat of water is heated on a hot wood stove. The water is recirculated through a heat exchanger to heat a remote living space.

Claims

1. A hydronic heating system water heater, comprising: a vat, an inlet pipe and an outlet pipe, the vat having a bottom, sides and an open top, the inlet pipe positioned through and sealed to the side of the vat, the outlet pipe positioned through and sealed to the side of the vat so that when the vat contains water and the vat is placed on a hot wood stove, the water in the vat is heated by the hot wood stove so that the hot water can be flowed from the vat through the outlet pipe through a heat exchanger and then back into the vat by way of the inlet pipe.

2. The system of claim 1, wherein the heat exchanger is a radiator for heating a living space.

3. The system of claim 1, wherein the heat exchanger heats a recirculated fluid flowed through a radiator for heating a living space.

4. A method for heating a first living space from heat generated by a wood stove located in a second living space by the steps of: heating an open container of water on a hot wood stove in a second living space to produce hot water; flowing the hot water through a radiator and then back to the open container, the radiator located in a first living space to heat the first living space.

5. A method for heating a first living space from heat generated by a wood stove located in a second living space by the steps of: heating an open container of water on a hot wood stove in a second living space to produce hot water; flowing the hot water through a heat exchanger and then back to the open container, conducting heat from the heat exchanger to a recirculated fluid flowed through a radiator to heat the first living space.

6. A method of cooling a first living space from cold well-water or a chilled liquid via a vat located in a second living space by the steps of: cooling an open container of water in a second living space from a well, flowing the cooled water through a heat exchanger and then back to the open container, conducting heat energy from the heat exchanger to a recirculated fluid flowed through a radiator to cool the first living space.

7. A method of heating domestic hot water used in conjunction with existing buffer tank technology.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0004] FIG. 1 is a drawing, part in cross section and part in full, of a highly preferred heat recovery vat (previously referred to as boiler pot) of the instant invention; and

[0005] FIG. 2 is a schematic drawing of a hydronic heating system incorporating the heat recovery vat shown in FIG. 1.

[0006] FIG. 3 is a drawing from above of a customized version of the heat recovery vat used to heat remote areas of the home.

DETAILED DESCRIPTION OF THE INVENTION

[0007] Referring now to FIG. 1, therein is shown a drawing, part in cross section and part in full, of a highly preferred heat recovery vat (2) of the instant invention. Stainless steel outlet pipe (5) is welded in an aperture in the side of stainless steel pot (2). Stainless steel inlet pipe (4) is welded in an aperture in the other side of stainless steel pot/vat (2). Pot/vat (2) is filled with water (6) and placed on a functional woodstove or alternative heating device (1).

[0008] Referring to FIG. 2, therein is shown a schematic drawing of a hydronic heating system incorporating heat recovery vat (8) shown in FIG. 1 (as 2). Heat Recovery Vat (8) is placed on hot wood burning stove (7) to heat the water contained in Heat Recovery Vat (8) to be flowed from outlet pipe (9) through liquid conduit 10, through heat exchanger (11), through liquid conduit 12, through pump (13) and then back into vat (8) by way of liquid conduit (14) through the outlet pipe (15). Heat exchanger (11) can be a radiator placed in, for example a bedroom while stove (7) is placed in a living room. However, the instant invention can also be incorporated with a pressurized hydronic system as shown in FIG. 2 wherein a heat transfer fluid is recirculated by pump 19 via liquid conduits 16, 18 and 20 through radiator (17).

[0009] Referring to FIG. 3, therein is shown a 2D drawing of a customized heat recovery vat (21), designed to maximize heat recovery from the chimney and woodstove surface. The welded inlet and outlet pipes are replaced with welded threaded apertures (22 & 23).

CONCLUSION

[0010] While the instant invention has been described above according to its preferred embodiments, it can be modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the instant invention using the general principles disclosed herein. Further, the instant application is intended to cover such departures from the present disclosure as come within the known or customary practice in the art to which this invention pertains.
