I I.

INVENTIO)N TITLE: WATER HEATING, STORAGE AND DISTRIBUTION SYSTEM. THE FOLLOWING STATEMENT IS A FULL DESCRIPTION OF THIS INVENTION, INCLUDING THE BEST METHOD OF PERFORMING IT KNOWN TO ME:- TIS INVENTION RELATES TO IMPROVEMENTS IN CONFIGURING SOLAR HEAT COLLECTION DEVICES, STORAGE FACILITIES AND DISTRIBUTION METHODS OF SOLAR HEATED WATER. FOR MANY PEOPLE THE ECONOMIC COST OF INSTALLING AND MAINTAINING- A. SOLAR WATER HEATING SYSTEM IS BEYOND THEIR REACH FINANCIALLY. THE SOLAR HEAT ,IN ECONOMIC AM) ENVIRONMENTAL T-ERMS,IS TOO VALUABLE A RESOURCE NOT TC-BE UTILISED TO ITS MAXIUM POTENTrIAL IN RELATION TO DRAWING ENERGY FROM THE SUN AND USING IT. EFFECTIVELY IN A COST EFFECTIVE WAY. THERE ARE MANY SOLAR BEATING SYSTEMS AVAILABLE ON THE MARKET WHICH ARE EFFECTIVE,IN RELATION TO THEIR PERFORMANCE, BUT THE COST OF MANUFACTURE, INSTALLATION AND MAINTENANCE MAKES THEM PROHIBITIVE TO MANY PEOPLE. FOR EXAMPLE THE PROBLEMS ASSOCIATED WITH THE EXPANSION OF WATER AT BOTH BELOW FOUR DEGREES CENTIGRADE AND AT TEMPERATfURE RISES ABOVE FOUR DEGRE~ES CENTIGRADE HAVE MADE IT DIFFICULT TO MANUFACTURE PRESSURISED SYSTMS10 WITHOUT THE NEED FOR ELABORATE SAFETY CONTROL DEVICES AND /OR HEAT AECONANGPLG UITS THE HIGH COST OF REPLACEMENT OF SOLAR COLLECTORS DAMAGED BY HAIL AND FALLING OBJECTS SUCH AS TREE LIMBS AND ALSO THE CORROSIVE EFFECT OF THE ENVIRONMENT ON MANY COMPLEX COLLECTORS. A THIRD EXAMPLE ESPECIALLY IN ROOF OR CEILING MOUNTED SYSTEMS IS THE NEED FOR EXTRA STRUCTURAL SUPPORT NECESSARY TO ACCOMMODATE THE EXTRA WEIGHT INCURRED AS A RESULT OF THIE NECESSITY TO STORE LARGE QUANTITIES OF WATER ADJACENT TO THE SOLAR COLLECTOR.

I

THESE PROBLEMS ARE OVERCOME BY THE PRESENT INVENTION, WHICH PROVIDES A REMOTE STORAGE FACILITY LOCATED AWAY FROM THE SOLAR COLLECTOR ENABLING A REDUCTION IN THE STRUCTURAL SUPPORT NECESSARY TO SUPPORT THE SYSTEM DUE TO ONLY SMALL QUANTITIES OF WATER BEING DIRECTED THROUGH THE SYSTEM AT ANY GIVEN TIME. THERE IS NO REQUIREMENT FOR ELABORATE SAFETY DEVICES OR EXPANSION PROTECTION DEVICES AS THE SYSTEM IS OPEN TO THE ATMOSPHERE ALLOWING FOR EXPANSION/ CONTRACTION MOVEMEN rS AND IS DRAINABLE IN TIMES OF IMMINENT DANGER FROM TEMPERATURES BELOW FOUR DEGREES CENTIGRADE WHICH MAY DAMAGE THE COLLECTOR DUE TO EXCESSIVE EXPANSION. THIS SYSTEM HAS THE BENEFIT OF ONLY HEATING THE WATER TO A TEMPERATURE WHICH IS NOT CONSIDERED HIGH ENOUGH TO CREATE A DANGER TO USERS THROUGH SCALDING HEAT CONTACT OR EXPLOSION DUE TO PRESSURE BUILD UP. ALSO THE SYSTEM IS AVAILABLE IN AN ECONOMICAL FORM DUE TO ALL OF ITS COMPONENTS BEING SIMPLE, INEXPENSIVE AND FREELY AVAILABLE ON THE OPEN MARKET. THE SYSTEM ALSO HAS THE ADDED ADVANTAGES OF BEING USEFUL AS AN INTERNALLY LOCATED HEAT STORAGE BANK USEFUL FOR THE HEATING OF AIR SPACES WITHIN AN ENCLOSED SPACE. THIS IS DONE BY LOCATING THE STORAGE VESSEL 25 WITHIN THIS SPACE AND ALLOWING CONVECTIVE AIR CURRENTS :o TO TRANSFER HEAT FROM THE STORAGE VESSEL TO THE AIR SPACE. THE SYSTEM COMPRISES A NON PRESSURISED VESSEL CAPABLE t OF STORING THE REQUIRED QUANTITY OF WATER AND A SERIES OF RESILIENT TUBULAR CONDUITS THE FIRST CONDUIT'GOES FROM THE LOWEST AND THEREFORE THE COOLEST POINT IN THE STORAGE F.CILITY TO THE SOLAR COLLECTOR FOR HEATING. THE SECOND CONDUIT GOES FROM THE SOLAR COLLECTOR OVERFLOW EITHER DIRECTLY TO A POINT OF USER NEED OR BACK TO THE STORAGE VESSEL.THE THITD CONDUIT IS THE USER SUPPLY CONDUIT KEPT AT THE HIGHEST POSSIBLE POINT BY MEANS OF A FLOATATION DEVICE NEAR THE END OF THE :00. TUBE TO ALLOW THE USER TO DRAW THE HOTTEST WATER 0: FROM THE STORAGE DEVICE .THE SYSTEM ALSO INCLUDES A PUMPING DEVICE EITHER MANUAL OR POWERED BY ELECTRICAL ENERGY AND A GATE VALVE AFTER THE PUMP TO STOP RETURN FLOW OF THE WATER INTO THE STORAGE CONTAINER UNTIL REQUIRED OR UNTIL NECESSARY DUE TO IMMINENT TEMPERATURES BELOW FOUR DEGREES 45 CENTIGRADE.

A SOLAR COLLECTOR WOULD ALSO BE REQUIRED COMPRISING OF THE FOLLOWING COMPONENTS- TWO MANIFOLDS,. ONE LOCATED HIGHER THAN THE OTHER AND JOINED f3Y A SERIES OF RESILIENT ,HEAT, PRESSURE AND SOLAR RADIATION RESISTANT, TUBULAR WATER CHANNELS CONNECTING THE THE BOTTOM TO THE TOP MANIFOLDS IN SUCH A WAY AS TO ALLOW THE FREE PASSAGE OF WATER BETWEEN THE TWO AND SEALED SO AS NOT TO ALLOW ANY WATER TO ESCAPE. THE MANIFOLDS ARE ALSO JOINED BY MEANS OF A SINGLE LARGE BORE PIPE CONNECTED AND SEALED INTO BOTH MANIFOLDS TO ALLOW A CONVECTIVE CURRENT TO TAKE PLACE WITHIN THE SOLAR COLLECTOR AND ALLOW THE HEATED WATER TO CONVECT TO T14E HIGHEST POINT IN THE SOLAR COLLECTOR FOR TRANSFERRAL BY THE RETICULATED TUBING TO THE STORAG7, FACILITY OR THE USERS POINT OF NEED. THIS SINGLE BORE PIPE WOULD HAVE A ONE DIRECTIONAL NON RETURN VALVE INSTALLED IN LINE TO STOP PUMPED WATER FROM BYPASSING THE THE TUBULAR so WATER CHANNELS. THE DETAILS REGARDING THE SOLAR COLLECTOR ARE NOT HEREIN DISCLOSED, S""TO ASSIST WITH UNDERSTANDING THE INVENTION, REFERENCE WILL NOW BE MADE TO THE ACCOMPANYING DRAWING FIGURE 1 WHICH SHOWS A SCHEMATIC EXAMPLE OF THE CONFIGURATION so 25..OF THE SYSTEM. REFERRING TO FIGURE 1, IT CAN BE SEEN THAT THE WATER HEATING, STORAGE AND DISTRIBUTION SYSTEM ACCORDING TO THIS INVENTION COMPRISES A STORAGE VESSEL A PUMP(2) Lt ."FOR PUMPING THE WATER FROM THE LOWEST POSSIBLE POINT THE VESSEL, A VALVE (3 )FCk CLOSING OFF THE RETURN OF 30 WATER INTO THE STORAGE VESSEL UNTIL REQUIRED, A RESILIENT TUBULAR CONDUIT FOR TRANSFERRING THE WATER TO A SOLAR COLLECTOR(5 MADE FROM RESILIENT a "MATERIALS CAPABLE OF CAPTURING THE SOLAR HEAT AND TRANSFERRING IT TO THE WATER PASSING THROUGH THE SOLAR COLLECTOR( AN OVERFLOW OUTLET (6 )AT THE HIGHEST POINT OF THE SOLAR COLLECTOR A RESILIENT TUBULAR CONDUIT FOR TRANSFERRING THE HEATED WATER BACK TO THE STORAGE VESSEL OR TO THE POINT OF USER NEED, A FLOATATION DEVICE( 8) CAPABLE OF KEEPING THE OPEN END OF A RESILIENT TUBULAR CONDUIT IMMERSED AT A POINT IN THE WATERWITHIN THE STORAGE VESSEL WHICH HAS THE GREATEST HEAT ENERGY AVAILABLE.

N I

AN OVERVIEW OF THE SY3TEM IS AS FOLLOWS- WATER IS TRANSFERED FROM A STORAGE VESSEL VIA A CONDUIT THROUGH A PUMP AND GATE VALVE TO A SOLAR COLLECTOR (5).IT FILLS THE COLLECTOR UNTIL AN OVERFLOW OCCURS AT THE OVERFLOW OUTLET WHICH IS SHOWN BY A RETURN OF WATER TO THE STORAGE VESSEL (1) VIA THE CONDUIT .AT THIS POINT TIE GATE VALVE IS TURNED OFF TO STOP FLOW IN THE CONDUIT AND THE PUMPING SYSTEM IS STOPPED. A TRANSFER OF HEAT EN-ERGY OCCURS FROM THE SOLAR RADIATOR VIA THE SOLAR COLLECTOR TO THE WATER HELD WITHIN ITS CONFINES. AFTER A SUITABLE PERIOD OF TIME THE WATER IS ALLOWED TO FLOW BACK INTO THE STORAGE VESSEL IN ONE OF TWO WAYS. THE FIRST IS TO OPEN THE GATE VALVE AND ALLOW THE HEATED WATER TO FLOW BACK BY GRAVITATION TO THE STORAGE VESSEL .THE SECOND WAY IS TO START TJ7E PUMP(2) AND OPEN THE GATE VALVE WHICH WILL FORCE THE.HEATED WATER TO FLOW OUT OF THE SOLAR COLLECTOR VIA THE OVRFLOW AND CONDUIT (7) EITHER BACK TO THE STORAGE VESSEL OA TO A POINT OF USER NEED VIA A VALVE NOT HEREIN DESCRIBED. @0•THE HEATED WATER IS REPLACED, IN THIS PRCESS, IN 0: ooTHE SOLAR COLLECTOR BY COOT!ER WATIER FROM THE 25 BOTTOM LEVEL OF THE STORAGE VESSEL TO BE HEATED IN THE METHOD AS STATED PREVIOUSLY. THE GATE VALVE IS AGAIN CLOSED AND THE PUMP(2) IS AGAIN TURNED OFF. THE WATER STORED WITHIN THE STORAGE VESSEL CAN BE DRAWN OFF TO A POINT OF USER NEED VIA AN OUTLET OF RESILIENT TUBULAR CONDUIT WHICH IS ATTACHED TO A 30 FLOATATION DEVICE IN SUCH A WAY AS TO RETAIN THE OPEN END OF THE CONDUIT AT A POINT IMMEDIATELY BELOW THE WATER LEVEL WITHIN THE STORAGE VESSEL THIS ENABLES .THE WATER WITH THE GREATEST AMOUNT OF HEAT ENERGY TO BE DRAWN OFF AT ANY GIVEN TIME. THE METHOD OF DRAWING WATER FROM.THE STORAGE VESSEL IS NOT INCLUDED HEREIN, THIS SYSTEM CAN BE ELECTRONICALLY CONTROLLED BUT THIS IS NOT DISCLOSED HEREIN.
