Definitions
- the invention generally relates to a heating system, and more particularly to a heating system utilizing electrolysis of water.
- the present heating system provides an efficient heat source for a home or other space where the system utilizes water, which is generally widely and abundantly available, as a fuel source without producing dangerous emissions.
- the present heating system further provides a heating unit that captures the heat emitted by various components within the unit, rather than relying upon only the burning of the hydrogen gas produced from the electrolysis process. Further, certain embodiments of the present invention allow a user to utilize commonly-available parts to construct the unit. Thus, the manufacturing cost of the system is kept minimal and the technology is made available to a greater percentage of the public.
- the heating system includes a tank in which water is stored.
- the water from the tank is passed to separation cells wherein electrolysis is performed.
- electrolysis the hydrogen and oxygen comprising the water molecules are separated to form hydrogen gas and oxygen gas.
- the hydrogen gas, oxygen gas, and any non-separated water are passed through a first heat exchanger, wherein the fluid within is cooled and heat is emitted. After passing through the first heat exchanger, the fluid is returned to the tank where the hydrogen gas and oxygen gas gather at the top of the tank and exit to a gas bubbler.
- the burn unit includes a flashback arrestor, an igniter, and a torch. After traveling through the flashback arrestor of the burn unit, the hydrogen gas is burned by the igniter and the torch flame resulting therefrom is directed to a second heat exchanger. The heat from the first heat exchanger, the separation cells, and burn unit are pushed through the system and out into the space to be heated by a series of fans. Other heat emitted by devices within the system is also gathered by the air flow directed by the series of fans.
- the heating system utilizes relatively little energy to perform electrolysis of water and generates a relatively large amount of heat for the amount of energy used.
- the emissions from the system are essentially only hydrogen gas, oxygen gas, and steam, i.e., non-toxic and non-harmful gases.

- the water, or water-electrolyte mix exits the tank 12 at the first tank outlet 16 , travels along the first conduit 74 and enters the pump inlet 28 of a pump 26 .
- the pump 26 compels the water, or water-electrolyte mix, to exit the pump 26 via a pump outlet 30 , where it is carried along a second conduit 74 to the cell inlet 34 of at least one separation cells 32 .

- the lower rear fan 68 in the back internal side of the internal case 70 pulls the environmental air from inside the internal case 70 to outside the internal case 70 and past the primary segment 44 of the first heat exchanger 42 . This encourages cooling of the fluids within the primary segment 44 , while the heat emitted from the primary segment 44 increases the temperature of the environmental air flowing by.
- the upper rear fan 68 then pulls the environmental air up past the separation cells 32 , and the heat emitted from the electrolysis process within the separation cells 32 further increases the temperature of the environmental air flowing thereby.

Description
- This application claims the priority date of the provisional application entitled “Home heating unit that utilizes hydrogen and oxygen separated from water” filed by Randy M. Bunn and Mark R. Akkerman on Jan. 29, 2009, with application Ser. No. 61/148,214, the disclosure of which is incorporated herein by reference.
- The invention generally relates to a heating system, and more particularly to a heating system utilizing electrolysis of water.
- Many different fuels have been used as heating sources, including wood, coal, natural gas, propane, heating oil, methane, and animal excrement, to name a few. Typically, these fuels are burned to generate heat. However, these fuels are not always in ready and abundant supply. Further, the fuels readily available in one area are not necessarily readily available in other areas. For example, in some parts of the world, wood and coal are readily available while propane and natural gas are not. In these areas, a heating system designed to utilize propane or natural gas as a fuel source will not be terribly helpful. Further, even in the areas where propane and natural gas are available, the cost of such fuels can often be prohibitive. Still further, the availability of such fuels is often largely dependent upon a third party. When such third parties unilaterally decided to limit the supply of the fuel, the end-user suffers from increased prices due to high demand or the bitter cold of insufficient supply. Finally, many of these fuels, when burned, produce emissions that are not safe for prolonged human exposure and that worsen problems of pollution.
- The present heating system provides an efficient heat source for a home or other space where the system utilizes water, which is generally widely and abundantly available, as a fuel source without producing dangerous emissions. The present heating system further provides a heating unit that captures the heat emitted by various components within the unit, rather than relying upon only the burning of the hydrogen gas produced from the electrolysis process. Further, certain embodiments of the present invention allow a user to utilize commonly-available parts to construct the unit. Thus, the manufacturing cost of the system is kept minimal and the technology is made available to a greater percentage of the public.
- As described in more detail below, the heating system includes a tank in which water is stored. The water from the tank is passed to separation cells wherein electrolysis is performed. During electrolysis the hydrogen and oxygen comprising the water molecules are separated to form hydrogen gas and oxygen gas. The hydrogen gas, oxygen gas, and any non-separated water are passed through a first heat exchanger, wherein the fluid within is cooled and heat is emitted. After passing through the first heat exchanger, the fluid is returned to the tank where the hydrogen gas and oxygen gas gather at the top of the tank and exit to a gas bubbler. In the gas bubbler water vapor and steam that may have exited the tank remain within the gas bubbler fluid while the hydrogen and oxygen gas pass out of the gas bubbler to a condenser and then to a burn unit or pass out of the gas bubbler and then directly to a burn unit. The burn unit includes a flashback arrestor, an igniter, and a torch. After traveling through the flashback arrestor of the burn unit, the hydrogen gas is burned by the igniter and the torch flame resulting therefrom is directed to a second heat exchanger. The heat from the first heat exchanger, the separation cells, and burn unit are pushed through the system and out into the space to be heated by a series of fans. Other heat emitted by devices within the system is also gathered by the air flow directed by the series of fans. As such, the heating system utilizes relatively little energy to perform electrolysis of water and generates a relatively large amount of heat for the amount of energy used. Further, the emissions from the system are essentially only hydrogen gas, oxygen gas, and steam, i.e., non-toxic and non-harmful gases.
- The purpose of the Summary is to enable the public, and especially the scientists, engineers, and practitioners in the art who are not familiar with patent or legal terms or phraseology to determine quickly, from a cursory inspection, the nature and essence of the technical disclosure of the application. The Summary is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.
- Still other features and advantages of the claimed system will become readily apparent to those skilled in the art from the following detailed description describing preferred embodiments of the system, simply by way of illustration of the best mode contemplated by carrying out the system. As will be realized, the system is capable of modification in various obvious respects all without departing from the invention. Accordingly, the drawings and description of the preferred embodiments are to be regarded as illustrative, and not restrictive.

- In the following description and in the figures, like elements are identified with like reference numerals. The use of “e.g.,” “etc.,” and “or” indicates non-exclusive alternatives without limitation unless otherwise noted. The use of “including” means “including, but not limited to,” unless otherwise noted.
- As shown in the
FIGS. 1 through 15 , disclosed is aheating system 10 utilizing electrolysis of water for heating a space. According to the depicted embodiments, theheating system 10 is contained within anexternal case 72. Theexternal case 72 preferably comprises a box-shaped housing made up of a front external side, a right external side, a left external side, a back external side, a bottom external side, and a top external side. Theexternal case 72 houses aninternal case 70 that divides the interior of theexternal case 72 into two sections. Theinternal case 70, which has an interior surface and an exterior surface, preferably comprises a box-shaped housing made up of a front internal side, a right internal side, a left internal side, a back internal side, a bottom internal side, and a top internal side. The bottom internal side rests atop the bottom external side. The front external side of theexternal case 72 has afan 68 attached in a lower area, i.e., a lowerfront fan 68. The front internal side defines afront fan opening 92. As arranged within theexternal case 72, thefront fan opening 92 aligns with thefan 68 in the lower front area of the front external side. Accordingly, thefront fan opening 92 is configured to encourage environmental air from the space to be heated to enter theexternal case 72 and theinternal case 70 from the space. - As shown in
FIG. 3 , theheating system 10 also includes atank 12 located mostly within theinternal case 70. Thetank 12 is configured to holdwater 96 and gases, specifically hydrogen and oxygen gases. Preferably, thetank 12 is configured to hold such gases under pressure. Further, preferably, thetank 12 includes an electrolyte such that thewater 96 and electrolyte form a water-electrolyte mixture. The electrolyte is preferably a compound configured to enhance the conductivity of water when the electrolyte is mixed therewith. Preferably, the electrolyte is a compound that is prone to disassociate into cations that are of a greater standard electrode potential than a hydrogen ion and into anions that are of a lower standard electrode potential than hydroxide. In some embodiments the electrolyte includes potassium hydroxide. In other embodiments, the electrolyte includes sodium hydroxide. In still other embodiments, the water-electrolyte mixture further includes an anti-foaming agent. In one such embodiment, the water-electrolyte mixture includes potassium carbonate as the electrolyte along with an anti-foaming agent, such as polydimethylsiloxane, silicone oil, vegetable oil, or another known, non-toxic, anti-foaming agent. - The
tank 12 defines atank refill port 14 in the upper area of thetank 12. Thetank refill port 14 is covered by a selectively-removable cap, which, when removed enables a user to refill thetank 12 via thetank refill port 14 withadditional water 96, electrolyte, or anti-foaming agent. Preferably, thetank refill port 14 aligns with atank port opening 84 defined in the top internal side of theinternal case 70. Thetank refill port 14 of thetank 12 extends out of theinternal case 70 through thetank port opening 84. As such, thetank refill port 14 is accessible outside of theinternal case 70 and readily accessible when theexternal case 72 is removed. - Also located within the
internal case 70 is apump 26 that has apump inlet 28 and apump outlet 30. Thepump 26 is powered by a power source. Thepump inlet 28 is operatively connected to afirst tank outlet 16 defined in thetank 12 via afirst conduit 74. Thefirst tank outlet 16 is preferably defined in a lower region of thetank 12, below the level of thewater 96 or water-electrolyte mixture within thetank 12. Thefirst conduit 74 is configured to pass thewater 96 or water-electrolyte mixture between thetank 12 and thepump 26 via thefirst tank outlet 16 and thepump inlet 28. Preferably, thefirst conduit 74 is insulated along its length so that the temperature of thewater 96 or water-electrolyte mixture within theconduit 74 is not excessively heated by the air within theinternal case 70 as it flows between thetank 12 and thepump 26. - Attached to the
pump outlet 30 is asecond conduit 74, which, according to the first depicted embodiment, passes outside of theinternal case 70 via a back conduit opening 90 defined in the back internal side (FIG. 5 ). Preferably thesecond conduit 74 is insulated along its length by being covered with insulation 76 (FIG. 7 ). Thesecond conduit 74 is also configured to pass the water or water-electrolyte mixture from thepump 26. - The
second conduit 74 is operatively connected to and is configured to pass the water or water-electrolyte mixture to thecell inlet 34 of aseparation cell 32 located outside of theinternal case 70 and mounted to the exterior surface of theinternal case 70. Preferably, and according to the depicted embodiments, a plurality ofseparation cells 32 are so mounted. For example, in the first depicted embodiment, shown inFIGS. 1 , 3, and 7, theheating system 10 includes twoseparation cells 32 operatively connected to one another in series. As another example, in the second depicted embodiment, shown inFIG. 2 , theheating system 10 includes twoseparation cells 32 operatively connected to one another in parallel. In the second depicted embodiment, the twoseparation cells 32 are operatively connected to one another via a number ofconduits 74. - While it is preferred that the water-electrolyte mixture pass from the
tank 12 to theseparation cells 32 via the use of apump 26, in other embodiments, nopump 26 is used, such that thetank 12 will be more directly operatively connected to theseparation cells 32, such as by oneconduit 74 extending between thefirst tank outlet 16 and thecell inlet 34. In some embodiments, theseparation cells 32 are incorporated with apump 26 as a single unit, such that noseparate pump 26 is necessary. In such embodiments, thepump 26, being contained within theseparation cells 32, will be located outside theinternal case 70. In still other embodiments,multiple pumps 26 are utilized or other devices are included along the flow between thefirst tank outlet 16 andcell inlet 34. In any regard, the water-electrolyte mixture exiting thetank 12 via thefirst tank outlet 16 is transported to theseparation cells 32. - Each of the
separation cells 32 contains a series of negatively-charged plates and positively-charged plates accordingly to knownseparation cell 32 designs. In some such designs, neutrally-charged, or non-charged, plates are also included in the series of positive and negative plates. In some embodiments, the plates within theseparation cells 32 are made of stainless steel. In other embodiments, the plates are made of platinum. In any regard, theseparation cells 32 are configured to perform electrolysis of water, preferably in the presence of an electrolyte. The size and number of plates included in eachseparation cell 32 is chosen depending on the amount of hydrogen and oxygen that is desired to be produced. That is, the larger the space to the heated, the greater the amount of hydrogen production will be desired, and the larger the surface area of the separation plates will likely be wanted. - The
separation cells 32 receive the water or water-electrolyte mixture via thesecond conduit 74, perform electrolysis of thewater 96 in the mixture in the presence of the electrolyte in the mixture, and produce a cell outlet mixture containing hydrogen gas and oxygen gas. Absent a completely efficient electrolysis performance, theseparation cells 32 will also produce water vapor. The electrolyte and other components of the water-electrolyte mixture, such as the anti-foaming agent, if used, will also be included in the cell outlet mixture. According to the first embodiment, the cell outlet mixture will be the mixture exiting the second of the twoseparation cells 32 in series. According to the second embodiment, the cell outlet mixture will be the combination of the mixtures exiting each of the twoseparation cells 32 in parallel. In either regard, the cell outlet mixture exits theseparation cells 32 via a cell outlet 36 (FIG. 7 ). The electrolysis process emits heat; thus, the cell outlet mixture exiting theseparation cells 32 will tend to be hotter than the water or water-electrolyte mixture that entered theseparation cells 32. - Connected to the
cell outlet 36 is afirst heat exchanger 42. In some embodiments, anotherconduit 74 operatively connects thecell outlet 36 to thefirst heat exchanger 42. According to the first embodiment, thefirst heat exchanger 42 includes aprimary segment 44 and a secondary segment 46 (FIG. 1 ). According to the second embodiment, thefirst heat exchanger 42 includes a plurality of tubes connected to one another in series in an S-configuration (FIG. 8 ). In other embodiments, thefirst heat exchanger 42 uses different conventional designs of simple heat exchangers. Also, according to the first embodiment, theprimary segment 44 of thefirst heat exchanger 42 is covered withinsulation 76 as it immediately exits theseparation cells 32 via thecell outlet 36. In other embodiments, theprimary segment 44 is not insulated. - The
first heat exchanger 42 is configured to pass the cell outlet mixture between theseparation cells 32 and thetank 12, where thefirst heat exchanger 42 is connected to thetank 12 at afirst tank inlet 18 defined in thetank 12 wall. According to the first depicted embodiment, thefirst tank inlet 18 is defined in a lower part of thetank 12, below the level of thewater 96 or water-electrolyte mixture within thetank 12. According to the second depicted embodiment, thefirst tank inlet 18 is defined in an upper part of thetank 12, above the level of thewater 96 or water-electrolyte mixture within thetank 12. - As shown in
FIG. 7 , theprimary segment 44 of thefirst heat exchanger 42 is preferably located outside of theinternal case 70 and is arranged in a coil configuration. Theprimary segment 44 is configured to accommodate cooling of the cell outlet mixture as it passes through theprimary segment 44 from theseparation cells 32. That is, as the cell outlet mixture travels through theprimary segment 44, heat from the cell outlet mixture will be emitted to environmental air. In other embodiments, thecell outlet 36 of theseparation cells 32 is connected with theprimary segment 44 of thefirst heat exchanger 42 via another conduit 74 (as shown inFIG. 1 ). - After traveling through the
primary segment 44, the cell outlet mixture will pass into athird conduit 74, which is connected to theprimary segment 44 of thefirst heat exchanger 42. Thethird conduit 74 passes from outside theinternal case 70 to inside theinternal case 70 via a back heat exchanger opening 98 defined in the back internal side of theinternal case 70. Preferably, the back heat exchanger opening 98 is defined in a lower area of the back internal side of theinternal case 70. Thus, thethird conduit 74 is configured to carry the cell outlet mixture that exits theprimary segment 44 of thefirst heat exchanger 42 into theinternal case 70 and to thesecondary segment 46 of thefirst heat exchanger 42, thesecondary segment 46 being connected to thethird conduit 74. - Though the first depicted embodiment connects the
primary segment 44 andsecondary segment 46 of thefirst heat exchanger 42 via aconduit 74, in other embodiments, theprimary segment 44 andfirst heat exchanger 42 are seamlessly joined. - The
secondary segment 46 of thefirst heat exchanger 42 receives the cell outlet mixture from thethird conduit 74 and eventually deposits it into thetank 12 via afirst tank inlet 18 defined in thetank 12 wall. Preferably, thefirst tank inlet 18 is defined in a lower area of thetank 12 wall, below thewater 96 or water-electrolyte level line. Thesecondary segment 46, located inside theinternal case 70, is arranged so as to encircle the tank 12 a number of times, preferably winding a number of times around thetank 12, winding from the top of thetank 12 to the bottom of thetank 12 where thesecondary segment 46 connects with thefirst tank inlet 18. Thus, thesecondary segment 46 is configured to pass the cell outlet mixture from thethird conduit 74 to thetank 12 via thefirst tank inlet 18. It is expected that the water-electrolyte mixture within thetank 12 will generally be cooler than the cell outlet mixture passing through thesecondary segment 46. As such, thesecondary segment 46, wound round thetank 12, is configured to accommodate further cooling of the cell outlet mixture, whereby additional heat is emitted from thesecondary segment 46. - When the cell outlet mixture is returned to the
tank 12, water vapor, electrolyte, and anti-foaming agent from the cell outlet mixture will tend to re-mix with the water-electrolyte mixture in thetank 12. The hydrogen gas and oxygen gas from the cell outlet mixture will tend to bubble up through the water-electrolyte mixture within thetank 12 to gather near the top of thetank 12. The hydrogen gas and oxygen gas will then be available to exit thetank 12 via asecond tank outlet 20 defined in an upper area of thetank 12 wall. Afourth conduit 74 is operationally connected to thesecond tank outlet 20 and is configured to pass the hydrogen gas and oxygen gas from thetank 12. Water vapor or steam that has accumulated in the same area will also pass out of thesecond tank outlet 20 via thefourth conduit 74. - The
heating system 10 further includes agas bubbler 48 preferably located within theinternal case 70. Thegas bubbler 48 contains a gas bubbler fluid, which is preferablywater 96. Thegas bubbler 48 defines agas bubbler inlet 50 and agas bubbler outlet 52 in an upper area of thegas bubbler 48, as shown inFIGS. 9 and 10 . Thegas bubbler inlet 50 extends down below the level of the gas bubbler fluid. Thus, according to the depicted embodiments, thegas bubbler inlet 50 extends below the level of thewater 96 within thegas bubbler 48. Because thegas bubbler inlet 50 extends down into the gas bubbler fluid, the hydrogen gas and oxygen gas that are passed from thetank 12 via thefourth conduit 74 will tend to bubble 100 up through the gas bubbler fluid to gather in an upper area of thegas bubbler 48. Preferably, the amount of gas bubbler fluid contained within thegas bubbler 48 is maintained at an amount to keep the level of the gas bubbler fluid at a level low enough to allow gas to gather in an upper area of thegas bubbler 48 but high enough to keep thegas bubbler inlet 50 extending to a submerged locale. - During operation, water vapor or steam that has passed from the
tank 12 into thegas bubbler 48 will be able to mix with the gas bubbler fluid and remain within thegas bubbler 48. Thegas bubbler outlet 52, which does not extend down below the level of the gas bubbler fluid, accommodates the exit of a gas bubbler mixture, which gas bubbler mixture will include the bubbled-up gases, particularly the hydrogen gas and oxygen gas, and, in some circumstances gas bubbler fluid vapors and/or steam. - According to the second depicted embodiment, shown in
FIG. 10 , thegas bubbler 48 is constructed from a readily-available water container, in which thegas bubbler inlet 50 andgas bubbler outlet 52 are defined in the lid of the water container. In some embodiments, such water container is a drinking water container. According to the first depicted embodiment, however, shown inFIG. 9 , thegas bubbler 48 is a custom-designed container with a reservoir within. Afifth conduit 74 is connected to thegas bubbler outlet 52. Thisfifth conduit 74 is configured to pass therethrough the gas bubbler mixture that exits thegas bubbler 48 via thegas bubbler outlet 52. - As shown in
FIG. 1 , thefifth conduit 74 of the first depicted embodiment passes to acondenser 56 via acondenser inlet 58 defined in an upper area of thecondenser 56. Thus, thefifth conduit 74 carries the gas bubbler mixture from thegas bubbler 48 to thecondenser 56. Thecondenser 56, preferably located within theinternal case 70, is configured to further cool the gas bubbler mixture such that the gas bubbler fluid, water vapor, or steam within the gas bubbler mixture will tend to condense and form a gas bubbler fluid condensate or water condensate, as the case may be. As such, thecondenser 56 is further configured to prevent water from traveling out of thecondenser outlet 60. The remaining hydrogen gas and oxygen gas will not form a condensate, but will pass out of thecondenser 56 via acondenser outlet 60 defined in thecondenser 56, preferably in an upper area. These gases will pass out of thecondenser outlet 60 through asixth conduit 74 connected thereto and configured to pass the hydrogen gas and oxygen gas therethrough away from thecondenser 56, outside of theinternal case 70 via a flashback arrestor opening 86 (FIG. 5 ) defined in the upper internal side, and to aburn unit 64 that is operatively connected to thesixth conduit 74. Theburn unit 64 is situated outside of theinternal case 70 and is directed toward the front external side. - Though in the first depicted embodiment, the gas bubbler mixture is passed through a
condenser 56 before the hydrogen gas and oxygen gas are passed to theburn unit 64, according to the second depicted embodiment, aconduit 74 carries the gas bubbler mixture with the hydrogen gas and oxygen gas from thegas bubbler outlet 52 of thegas bubbler 48 direct to theburn unit 64, as shown inFIG. 2 . Thisconduit 74 is preferably angled and configured to prevent water or other liquid from making an upward siphon back to theburn unit 64. - The
burn unit 64 includes a flashback arrestor connected to an igniter, which is configured to light a torch. The igniter portion of theburn unit 64 is configured to burn, as the torch flame, the hydrogen gas passing into the igniter portion from the flashback arrestor portion of theburn unit 64. The flashback arrestor portion of theburn unit 64 is configured to prevent the igniter portion from burning the hydrogen gas contained within thesixth conduit 74 that connects to theburn unit 64. According to the embodiment depicted inFIG. 11 , the flashback arrestor portion of theburn unit 64 includes a flashback arrestornarrow fitting 104 connected to a flashback arrestor wide fitting 106, which is joined with aflashback arrestor tube 110 on a proximate end. In some embodiments, the flashback arrestornarrow fittings 104 are barb fittings. Theflashback arrestor tube 110 is joined with another flashback arrestor wide fitting 106 on the opposite, distal end. This second flashback arrestor wide fitting 106 is connected with a flashback arrestornarrow fitting 104 that is tipped with aflashback arrestor tip 102. The torch flame is produced at theflashback arrestor tip 102. In some embodiments, theflashback arrestor tip 102 is a chuck fitting that is tapped for a 0.025 mig tip and the flashback arrestorwide fittings 106 are quarter inch pipe fittings. Theflashback arrestor tip 102 includes an orifice configured to reduce the exiting gas stream to a size conducive for forming the torch flame. Between the two flashback arrestorwide fittings 106 aremesh screens 108 configured to discourage the flame from passing therethrough to ignite hydrogen gas contained on the other side. In some embodiments, theflashback arrestor tube 110 comprises a copper tube and the mesh screens 108 comprise bronze wool. In other embodiments, theflashback arrestor tube 110 is filled with the mesh, rather than just being bordered by mesh screens 108. According to the first depicted embodiment, theburn unit 64 is arranged in a bent shape, as shown inFIG. 3 . According to the second depicted embodiment, theburn unit 64 is arranged in a straight shape, as shown inFIG. 2 . In other embodiments, the flashback arrestor of theburn unit 64 is designed according to other known methods. - Should the hydrogen gas contained within the
sixth conduit 74 become ignited, though unintentional, the gas bubbler fluid within thegas bubbler 48 will also serve as a flashback arrestor, a wet flashback arrestor. Accordingly, the gas bubbler fluid within thegas bubbler 48 is preferably a noncombustible substance, such as water. - Because the
burn unit 64 is directed toward the front external side of theexternal case 72, the heat generated from the burning of the hydrogen gas will also be directed toward the front external side of theexternal case 72. Located between theburn unit 64 and the surface of the front external side of theexternal case 72 is a second heat exchanger 66 (FIGS. 12 and 13 ). Thesecond heat exchanger 66 preferably includes a plurality of secondheat exchanger tubes 116 bound together in a bundle, in close proximity with one another, preferably coming into contact with a number of other secondheat exchanger tubes 116. The bundle is attached viacase mounting brackets 114 to the exterior surface of theinternal case 70. In some embodiments, the secondheat exchanger tubes 116 comprise pipes made of copper, aluminum, or other conductive material. In some embodiments, thesecond heat exchanger 66 further includes at least oneextended tube 112 toward which theburn unit 64 is specifically pointed. Preferably, in such embodiments, the flame from the torch of the igniter within theburn unit 64 is enters theextended tube 112 of thesecond heat exchanger 66. As such the torch flame directly heats theextended tube 112 and then the heat is dissipated through the remainder of the secondheat exchanger tubes 116. In other embodiments, thesecond heat exchanger 66 includes secondheat exchanger tubes 116 of all equal lengths. Thesecond heat exchanger 66 is configured such that the heat emitted by theburn unit 64 heats the environmental air within and surrounding thesecond heat exchanger 66 before the heated air exits the side of thesecond heat exchanger 66 nearest to the front external side of theexternal case 72. - Opposite the exiting side of the
second heat exchanger 66, anfan 68 is mounted within the front external side of theexternal case 72. This upperfront fan 68 is aligned with thesecond heat exchanger 66 and is configured to encourage heat emitted from thesecond heat exchanger 66 to exit theexternal case 72 and enter the space outside theheating system 10, i.e., the space theheating system 10 is to heat. - Another
fan 68 is preferably mounted within a back fan opening 94 (FIG. 5 ) defined in the back internal side of theinternal case 70. Thisrear fan 68 is configured to encourage environmental air to pass from inside theinternal case 70 to outside theinternal case 70, while still being within theexternal case 72. Thus, therear fan 68 encourages environmental air to flow past theprimary segment 44 of thefirst heat exchanger 42. - Preferably, a
fourth fan 68 is positioned above theseparation cells 32 and is configured to direct heat emitted from theseparation cells 32 toward the upperfront fan 68. As such, this upper rear fan 68 (shown inFIG. 1 ) is located outside of theinternal case 70, but inside theexternal case 72. In some embodiments, the upperrear fan 68 is mounted to the interior surface of theexternal case 72. In other embodiments, the upperrear fan 68 is mounted to the exterior surface of theinternal case 70. As shown in the embodiment depicted inFIG. 14 , the upperrear fan 68 comprises aduct fan subsystem 118, which includes aheating system 10 situated above theseparation cells 32 and directed upward. Situated above theduct fan 120 is avent fan 122, such as one in the style of a bathroom ceiling fan, which is configured to direct the air leaving theduct fan 120 in a direction perpendicular to the direction in which theduct fan 120 is directed. Preferably, attached to the exit port of thevent fan 122 is a reducingtube 124 configured to focus the heated air toward the direction of thesecond heat exchanger 66 and thereafter the upperfront fan 68. In other embodiments, a plurality of reducingtubes 124 are attached to the exit port of thevent fan 122 with each of the reducingtubes 124 focusing the heated air toward a different secondheat exchanger tube 116 of thesecond heat exchanger 66. - The
heating system 10, as depicted, therefore comprises a heating unit that is configured to heat a space utilizing water as a fuel for an electrolysis process. According to the first depicted embodiment, diagramed inFIG. 1 , the water, or water-electrolyte mix, is first retained within thetank 12. The water, or water-electrolyte mix, exits thetank 12 at thefirst tank outlet 16, travels along thefirst conduit 74 and enters thepump inlet 28 of apump 26. Thepump 26 compels the water, or water-electrolyte mix, to exit thepump 26 via apump outlet 30, where it is carried along asecond conduit 74 to thecell inlet 34 of at least oneseparation cells 32. Within theseparation cells 32, the electrolysis process is carried out, and the results of that process exit theseparation cells 32 via thecell outlet 36 and are carried away via theprimary segment 44 of afirst heat exchanger 42 where the fluids are cooled, or by anotherconduit 74 that connects thecell outlet 36 with theprimary segment 44. From theprimary segment 44, the fluids pass through athird conduit 74 to thesecondary segment 46 of thefirst heat exchanger 42 where the fluids are again cooled as they circle thetank 12. The fluids enter through thefirst tank inlet 18 into thetank 12. The gases within the fluids travel through the water, or water-electrolyte mixture, within thetank 12 and out thesecond tank outlet 20 to afourth conduit 74, which carries the gases or other fluids to thegas bubbler inlet 50 of thegas bubbler 48. The gases are bubbled through the gas bubbler fluid therein and exit thegas bubbler 48 via thegas bubbler outlet 52. They are carried away from thegas bubbler 48 via afifth conduit 74 and into thecondenser inlet 58 of acondenser 56. Gases that did not condense within thecondenser 56 exit thecondenser 56 via thecondenser outlet 60 and travel through asixth conduit 74 to theburn unit 64, wherein the hydrogen gas is ignited and generates heat this is directed toward thesecond heat exchanger 66. - As the fluids are traveling through the
heating system 10, environmental air from the space to be heated is also traveling through the system and being heated, as indicated by theenvironmental air flow 78 arrows depicted inFIG. 1 . That is, environmental air from the space to be heated is pulled into theexternal case 72 andinternal case 70 via the lowerfront fan 68, which pushes the environmental air past thesecondary segment 46 of thefirst heat exchanger 42, thereby encouraging the cooling of the fluids within theprimary segment 44. The environmental air picks up the heat that is emitted from thesecondary segment 46 of thefirst heat exchanger 42 and then travels past thepump 26. Thepump 26 also emits heat as it is operated, thereby increasing the temperature of the environmental air. The lowerrear fan 68 in the back internal side of theinternal case 70 pulls the environmental air from inside theinternal case 70 to outside theinternal case 70 and past theprimary segment 44 of thefirst heat exchanger 42. This encourages cooling of the fluids within theprimary segment 44, while the heat emitted from theprimary segment 44 increases the temperature of the environmental air flowing by. The upperrear fan 68 then pulls the environmental air up past theseparation cells 32, and the heat emitted from the electrolysis process within theseparation cells 32 further increases the temperature of the environmental air flowing thereby. The upperrear fan 68 directs the air toward theburn unit 64, where the heat emitted from the burning of the hydrogen gas released during electrolysis further adds to the heat of the environmental air, which heating is also aided by thesecond heat exchanger 66. The upperfront fan 68 then pulls the heated environmental air outside of theexternal case 72 and into the space to be heated. Accordingly, the heat emitted by thepump 26, the heat emitted by theprimary segment 44 andsecondary segment 46 of thefirst heat exchanger 42, the heat emitted by theseparation cells 32, and the heat emitted by theburn unit 64 all contribute to increase the temperature of the environmental air fed back into the space to be heated. - Preferably, the
pump 26,fans 68,separation cells 32, and burnunit 64 are all powered by a shared power source (not shown). Also preferably, this power source is located within theexternal case 72, if not also theinternal case 70. Therefore, the heat given off by the power source during operation will also contribute to increasing the temperature of the environmental air flowing through theheating system 10. Likewise, any heat given off by thefans 68 during operation will also be captured and fed out of theheating system 10. - As the
tank 12,gas bubbler 48, andcondenser 56 will all, during operation, hold some amount of fluid,likely water 96, it is further preferred that thetank 12 further define atank port opening 84 and atank bubbler port 22 and atank condenser port 24. Likewise, thecondenser 56 defines acondenser fluid port 62 and thegas bubbler 48 defines a gasbubbler fluid port 54. Preferably, thecondenser fluid port 62 is defined in a lower area of thecondenser 56, and the gasbubbler fluid port 54 is defined in a lower part of thegas bubbler 48. Aseventh conduit 74 operatively connects thetank bubbler port 22 with the gasbubbler fluid port 54, and an eightconduit 74 operatively connects thetank condenser port 24 with thecondenser fluid port 62. Along theseventh conduit 74 and the eightconduit 74 are located valves configured to selectively open theconduits 74 to allow communication between thetank 12 and therespective condenser 56 orgas bubbler 48. As such, when the level of gas bubbler fluid within thegas bubbler 48 becomes undesirably low, the valve along theseventh conduit 74 can be operated to allowwater 96 or water-electrolyte mixture contained within thetank 12 to flow into thegas bubbler 48 so as to raise the level of gas bubbler fluid within thegas bubbler 48. Contrarily, when the level of gas bubbler fluid within thegas bubbler 48 becomes undesirably low, the valve along theseventh conduit 74 can be operated to allow gas bubbler fluid within thegas bubbler 48 to transfer to thetank 12, thereby lowering the level of gas bubbler fluid within the 48. Similarly, when the amount of condensate within thecondenser 56 becomes undesirably great, the valve along theeighth conduit 74 can be operated to allow transfer of the condensate to thetank 12, thereby lowering the level of the condensate within thecondenser 56. Contrarily, if additional liquid within thecondenser 56 becomes desired, the valve along theeighth conduit 74 can be operated to allow transfer ofwater 96 or water-electrolyte mixture from thetank 12 to thecondenser 56, thereby raising the level of the fluid within thecondenser 56. - It is further preferred that the
heating system 10 include an on/offswitch 80, accessible from outside theexternal case 72, and configured to power on the power source so as to start the operation of theheating system 10. Ideally, theheating system 10 also includes a on/off light 82 configured to indicate whether or not theheating system 10 is turned on and in operation. In some embodiments, theheating system 10 also includes temperature sensors and fluid level sensors so as to provide data on the operating conditions of the system, which data can be utilized to prevent unsafe conditions, such as when thewater 96 levels within thetank 12 grow too low or when the temperatures within theconduits 74 grow too high. These sensors are further used to indicate to a user when thewater 96, electrolyte, and/or anti-foaming agent within thetank 12 need to be replaced or refilled via thetank refill port 14. - This
gas bubbler 48 further defines a gasbubbler fluid port 54, preferably in a lower region of thegas bubbler 48. The gasbubbler fluid port 54 is operatively connected with thetank 12 via anotherconduit 74 that is configured to pass water and/or gas bubbler fluid between thegas bubbler 48 and thetank 12 via atank bubbler port 22 defined in thetank 12 wall. Preferably - As the
heating system 10 is configured to heat a space, it is further configured to be incorporated into a traditional furnace system to form afurnace hybrid system 126, as shown inFIG. 15 . As shown, the traditional furnace system includes afurnace heat box 130 that receives air to be heated acold air return 128. The heated air exits thefurnace heat box 130 through furnacehot air ducts 132. To incorporate theheating system 10 into the traditional furnace system to form afurnace hybrid system 126, a secondarycold air duct 134 is spliced into thecold air return 128 and fed to the lowerfront fan 68 of theheating system 10. A secondaryhot air duct 136 is spliced into the furnacehot air ducts 132 and is connected to the upperfront fan 68 of theheating system 10. Breezeblockers 138, or one-way vents, are included in both the secondarycold air duct 134 and the secondaryhot air duct 136 to prevent the air within the secondarycold air duct 134 and the secondaryhot air duct 136 from traveling in the opposite direction, and against thefans 68 of theheating system 10. - Preferably, the
conduits 74 of theheating system 10 are made of conductive metal tubes or pipe, to allow ready dissipation of heat where theconduits 74 are not covered byinsulation 76. - Also, preferably, the level of the
water 96 or water-electrolyte mixture within thetank 12 is kept at a level below the top of thetank 12, so that a space is left at the top of thetank 12 wherein hydrogen and/or oxygen gas can gather and remain until the system is put into operation to burn the hydrogen gas with theburn unit 64. Accordingly, as hydrogen gas and oxygen gas are produced by theseparation cells 32, if theheating system 10 is turned off, the as-yet-unused gases will be retained largely within thetank 12 until theheating system 10 is restarted. - The exemplary embodiments shown in the figures and described above illustrate, but do not limit, the system. It should be understood that there is no intention to limit the system to the specific form disclosed; rather, the system is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the invention as defined in the claims. For example, while the exemplary embodiments illustrate the use of a number of
conduits 74, the system is not limited to use with the conduits arranged only as depicted, but may be used with a different number of conduits differently positioned. For example, in some embodiments, the front internal side of theinternal case 70 further defines a upper conduit opening 88 configured to allowconduits 74 to pass from inside theinternal case 70 to outside theinternal case 70, or vice versa. The upper conduit opening 88 is further configured to allow electrical cords to connect the power source with theseparation cells 32 or other devices external to theinternal case 70 needing power. Still further, while the exemplary embodiments locate a number of the components of theheating system 10 external to theinternal case 70, in other embodiments, the components, including theprimary segment 44 of thefirst heat exchanger 42 and theseparation cells 32 are arranged to be inside theinternal case 70. Moreover, while in the first depicted embodiment, thefirst heat exchanger 42 includes aprimary segment 44 and asecondary segment 46, with theprimary segment 44 being arranged in a coil configuration and with thesecondary segment 46 being arranged in a coil configuration winding around thetank 12, in other embodiments, thefirst heat exchanger 42 comprises a single coil that winds around thegas bubbler 48, rather than around thetank 12, before passing back into thetank 12. - Further, while the system is not limited to use with the heating of rooms in a home, it is expected that various embodiments of the system will be particularly useful in such situations. In any regard, the foregoing description should not be construed to limit the scope of the invention, which is defined in the following claims.
- Accordingly, while there is shown and described the present preferred embodiments of the system, it is to be distinctly understood that this system is not limited thereto but may be variously embodied to practice within the scope of the following claims. From the foregoing description, it will be apparent that various changes may be made without departing from the spirit and scope of the invention, as defined by the following claims.
