This invention relates generally to a heating system, and more particularly to an improved closed loop heating system which is durable and reliable, that possesses easily removable or replaceable heating elements, and which can be easily installed in a home.
It is well known that furnaces are used to heat homes. Traditionally, such furnaces were oil furnaces. However, as the demand for oil has risen sharply in the last decade, the price has correspondingly risen sharply, reducing the ability of such furnaces to be economical to the home or business owner. Recently, gas-fired furnaces, using natural gas, have been much in demand for homeowners in economically heating their home. However, much as has occurred with oil, natural gas has also seen large price increases in the last couple of years, which has also reduced the economical viability of gas-fired furnaces.
It is also well known to heat homes using, for example, electrical baseboards, but, as hydro rates have risen quite sharply recently, and can be expected to continue upwardly in the future, these types of devices are not necessarily economical also. What is required is a heating system which is very economical, and which can generate substantial amounts of heat to heat larger spaces, such as in a home or business. Thus, there is a further need for an improved environmentally friendly heating system for heating a space which has a generally uncomplicated and simple design, which may be installed easily, and is durable and reliable, and which possesses easily removable or replaceable heating elements.
There is also a need for an improved closed loop heating system which utilizes environmentally friendly heating elements which have a generally uncomplicated and simple design, which may be installed or removed easily, and which, by virtue of its design, are more durable and reliable to withstand the constant flow of coolant or fluid flowing around it over time. There is also a further need for an improved closed loop heating system using heating elements having a greater surface area so as to contact the coolant or fluid flowing past and around it, therefore heating the coolant or fluid in a faster and more efficient manner. In this regard, the present invention substantially fulfills this need.
It is an object and advantage of the present invention to provide an improved heating system which is environmentally friendly and extremely economical, and which has a generally uncomplicated and simple design, and which may be installed easily.
It is another object and advantage of the present invention to provide an improved heating system which is durable and reliable, and which possesses easily removable or replaceable heating elements.
It is another object and advantage of the present invention to provide an improved heating system which can be run with a minimum of electrical power, and yet which can generate substantial amounts of heat to heat larger spaces.

A preferred embodiment of the present invention is described below with reference to the accompanying drawings, in which:
In the preferred embodiment, and with reference to
As can be seen in
The housing 3 is interconnected with a first flow pipe 19 and a second flow pipe 21 which are interconnected at ends 23 thereof to form a closed loop fluid flow circuit, wherein the heat transfer fluid 7, or water, may flow. The closed loop fluid flow circuit will preferably be in a vacuum environment. A pump 6 is also utilized to continuously circulate the heat transfer fluid 7, or water, through the fluid flow circuit.
As can also be readily seen in
When positioned within the internally defined chambers 11 within the body of the housing 3 the heating element 17 comprises, as shown in
The heating elements 17 in the housing 3 are supplied with electrical power from a power source 25 for enabling the heating elements 17 to heat the heat transfer fluid 7, or water, within the fluid flow circuit. For example, some electrical heating elements can be heated to 3500 degrees, or temperatures in varying other degrees, and this, in combination with the temperatures generated by other elements in the housing, amounts to a considerable temperature which can be generated to heat the fluid flowing in the fluid flow circuit. In one embodiment, the power source 25 is an electrical type power source, or a DC power pack that can be plugged in by means of a power cord (not shown), though it is conceivable that, alternatively, other types of power sources could be utilized, such as solar power cells, A/C power, DC power pack, wind generated power sources or the like, as would be apparent to one skilled in the art. Of course, it would be readily apparent that such a power cell could also be re-energized or re-charged also, as is also known in the art. The power from the power source 25 is connected to the heating elements 17 by means of data board 27 and wiring 29. In a preferred embodiment, the power source 25 is a DC power pack and can be easily unplugged and replaced from the system if necessary, whereby a new power pack can be inserted.
A lower end 35 of the stem 34 will, preferably, be L-shaped, the lower end 35 thus being substantially perpendicular in relationship to the stem 34. The outermost end 36 of the lower end 35 will preferably be tapered, at least slightly. In this manner, when the heating element 17 is inserted into chambers 11 of the housing 3, so as to project downwardly into the passage 5 of the housing 3 to be direct contact with the heat transfer fluid 7, the tapered outermost end 36 of the lower end 35 will act as a breakwater to the onrushing coolant flowing past it in the passage 5, (the directional passage flow of the fluid being shown as “A” in
Moreover, by virtue of the lower end 35 of the stem 23 being L-shaped, the lower end 35 possesses a greater surface area with which to contact, and thus heat the heat transfer fluid 7. This effectively means that heat transfer fluid 7 can be heated at a faster rate than a conventional electric heating element, since the heat transfer fluid 7 is separated and heated by both sides of the lower end 35, rather than just encountering, and being heated by, the immediate, and only, surface of a straight conventional electric heating element projecting downwardly in passage 5 to contact the flow of the heat transfer fluid 7. And, by virtue of the tapered outermost end 36 of the lower end 35 forcing the heat transfer fluid 7 to flow past both side of the lower end 35, the lower end 35 is thus enabled to heat the heat transfer fluid 7 in smaller quantities, since the heat transfer fluid 7 is effectively being split in half by the breakwater qualities of tapered outermost end 36.
As can be seen in
Surrounding a substantially middle portion of the stem 59 and the insulating sheath 55 is a threaded portion 57, by which the electric heating element 52 can be threadably fixed and inserted into chambers 11 of the housing 3. A lower end 61 of the stem 59 is substantially angled at a 45 degree angle and projects into the passage 5 of the housing 3 whereby the heating element 52 is in direct contact with the heat transfer fluid 7, the lower end thus being substantially perpendicular in relationship to the stem 59 and the remainder of the heating element 52, giving the lower end 61 of the heating element 52 a greater surface area with which to contact, and thus heat the heat transfer fluid 7.
The outermost point 63 of the lower end 61 will preferably be tapered, at least slightly. In this manner, when the electric heating element 52 is inserted into chambers 11 of the housing 3, so as to project downwardly into the passage 5 of the housing 3 to be in direct contact with the heat transfer fluid 7, the tapered outermost point 63 of the lower end 61 will act as a breakwater to the onrushing heat transfer fluid 7 flowing past it in the passage 5, (the directional passage flow of the heat transfer fluid 7 being shown as “A” in
Moreover, by virtue of the lower end 61 of the stem 59 being substantially angled at a 45 degree angle, the lower end 61 possesses a greater surface area with which to contact, and thus heat the heat transfer fluid 7. This effectively means that heat transfer fluid 7 can be heated at a faster rate than that accomplished by a conventional heating element, since heat transfer fluid 7 is separated and heated by both sides of the lower end 61, rather than just encountering, and being heated by, the immediate, and only, surface of a conventional heating element projecting downwardly in passage 5 to contact the flow of heat transfer fluid 7. And, by virtue of the tapered outermost point 63 of the lower end 61 forcing the heat transfer fluid 7 to flow past both sides of the lower end 61, the lower end 61 is thus able to heat the heat transfer fluid 7 flowing past it in smaller quantities, since the heat transfer fluid 7 is effectively being split in half by the breakwater qualities of tapered outermost point 63, and the lower end 61 is effectively in contact with both halves of the heat transfer fluid 7 flowing past it. It will of course be understood that the lower end 61 of the stem 59 of the electric heating element 52 can be substantially angled at from between a 45 degree angle to a 90 degree angle when it is inserted into the housing 3 to project into the passage 5.
In a preferred embodiment, and as shown in
In a further embodiment, the heating system 1 includes a thermostatic safety control 18 in association with the heating elements 17, which could be installed within or on the housing 3 so as to be in association with the heating elements 17 and the other components therein, in a conventionally known manner. In a preferred embodiment, each of the heating elements 17 will have a corresponding thermostatic safety control 18 associated therewith. Each thermostatic safety control 18 is adapted to turn the heating element 17 off when a temperature of the heat transfer fluid 7 within the fluid flow circuit and the housing 3 exceeds a pre-determined level, or when it is detected that a component has failed. For example, if the pump 6 malfunctions and is no longer circulating the heat transfer fluid 7 in the housing 3, each thermostatic safety control 18 activates to shut down each of the heating elements 17. Moreover, in the event of a power surge to the system, or in the event the system is too hot or too cold, each thermostatic safety control 18 activates to shut down each of the heating elements 17 to prevent damage to the system.
In an alternative embodiment, as shown in
In a further embodiment, the heating system of the present invention, for example, could be utilized as a radiant floor heating system. With reference to
The housing 91 is interconnected with a first flow pipe 81 and a second flow pipe 84 which are interconnected at ends 83 thereof to form a closed loop fluid flow circuit, wherein the heat transfer fluid may flow. The closed loop fluid flow circuit will preferably be in a vacuum environment. A pump 93, which can of a conventional sort, is also utilized to continuously circulate the heat transfer fluid through the fluid flow circuit.
As can also be readily seen in
The heating elements 87 in the housing 91 are supplied with electrical power from a power source 71 for enabling the heating elements 87 to heat the heat transfer fluid within the fluid flow circuit. For example, some electrical heating elements can be heated to 3500 degrees, or temperatures in varying other degrees, and this, in combination with the temperatures generated by other elements in the housing, amounts to a considerable temperature which can be generated to heat the fluid flowing in the fluid flow circuit. In one embodiment, the power source 71 is an electrical type power source, or a DC power pack that can be plugged in by means of a power cord (not shown), though it is conceivable that, alternatively, other types of power sources could be utilized, such as solar power cells, A/C power, DC power pack, wind generated power sources or the like, as would be apparent to one skilled in the art. Of course, it would be readily apparent that such a power cell could also be re-energized or re-charged also, as is also known in the art. The power from the power source 71 is connected to the heating elements 87 by means of circuit board 89 and wiring 78. In a preferred embodiment, the power source 71 is a DC power pack and can be easily unplugged and replaced from the system if necessary, whereby a new power pack can be inserted.
The embodiment of the heating system 70 includes a thermostatic safety control 79 in association with the heating elements 87, which could be installed within or on the housing 91 so as to be in association with the heating elements 87 and the other components therein, in a conventionally known manner. In one embodiment, each of the heating elements 87 will have a corresponding thermostatic safety control 79 associated therewith. Each thermostatic safety control 79 is adapted to turn the heating element 87 off when a temperature of the fluid within the fluid flow circuit and the housing 91 exceeds a pre-determined level, or when it is detected that a component has failed. For example, if the pump 93 malfunctions and is no longer circulating the fluid in the housing, thermostatic safety controls 79 activates to shut down each of the heating elements 87. Moreover, in the event of a power surge to the system, or in the event the system is too hot or too cold, thermostatic safety controls 79 activates to shut down each of the heating elements 87 to prevent damage to the system.
