A hot water heater with a built in refrigerant heat recovery system is provided. A thermosyphon and Coriolis force powered refrigeration heat recovery unit is integrated into the tank of a conventional gas or electric hot water heater. The heat recovery unit is placed beneath the outer skin of the hot water heater to decrease the number of exterior connections and increase the ease of installation. The use of the Coriolis effect increases the flow rate and thus the efficiency of the heat transfer system.

I claim: 1. A heat recovery system for utilizing excess heat produced by an external heat source, said system comprising: a hot water tank for storing a reservoir of hot water; a thermosyphon system wrapped around and in direct contact with, said hot water tank in a counter-clockwise direction for removing relatively cold water from a lower region of the hot water tank and introducing relatively hot water into an upper region of the hot water tank such that water flows in said system at least in part due to Coriolis effect when the heat recovery system is used in the northern hemisphere of the world to increase a flow rate of the water from the hot water tank through the thermosyphon system. 2. The system of claim 1 wherein the system further comprises a water heater and the thermosyphon system is incorporated within the outerskin of the water heater such that the water heater only has four external connections, said four external connections comprising: a cold water inlet for receiving cold water from an external water source; a hot water outlet for providing hot water for external use; a heated fluid inlet for receiving heated fluid from the external heat source; and a cooled fluid outlet for returning cooled fluid to the external heat source. 3. The system of claim 2 wherein hot water is removed from the hot water tank from the same port that heated water is introduced from the heat transfer unit into the hot water tank. 4. The system of claim 1 wherein the relatively cold water is removed from the hot water tank trough a sediment removal port located on the bottom of the hot water tank. 5. The system of claim 1 wherein the external heat source is an air conditioning unit, refrigeration unit or heat pump unit. 6. The system of claim 1 wherein the thermosyphon system further comprises a tube-on-tube heat exchange system and wherein a heated fluid is received from the external heat source in a first tube and relatively cold water from the water tank is received in a second tube and the first and second tubes are positioned to contact one another such that heat is transferred from the heated fluid to the relatively cold water and wherein the first and second tube are wrapped around the exterior of the hot water tank such that the Coriolis effect increases a flow rate in the second tube. 7. A method of recovering heat produced by an external heat source positioned in the northern hemisphere of the world, said method comprising: providing a heated fluid from the external heat source to a water heater having a hot water tank through a hot fluid inlet; removing relatively cold water from a lower region of the hot water tank from a tank outlet; transferring heat from the heated fluid to the relatively cold water with a heat transfer unit wrapped around, and in direct contact with, said hot water tank in a counter-clockwise direction and thereby heating the relatively cold water; reintroducing the heated water to an upper region of the hot water tank through a heated water tank inlet; and returning the cooled fluid to the external heat source through a cooled fluid outlet; wherein a thermosyphon effect and a Coriolis effect are utilized to remove the relatively cold water from the hot water tank and to reintroduce the heated water into the hot water tank. 8. The method of claim 7 further comprising configuring the water heater such that the heat transfer is accomplished within an outer skin of the water heater. 9. The method of claim 7 wherein the step of transferring the heat further comprises channeling the heated fluid through a first tube and channeling the relatively cold water through a second tube wherein the first tube and the second tube are positioned to be in contact such that heat is transferred from the heated fluid to the relatively cold water. 10. The method of claim 7 wherein the step of transferring the heat further comprises transferring heat from the heated fluid to the relatively cold water through a tube-in-tube heat exchanger. 11. The method of claim 9 further comprising the step of coiling the first tube and the second tube around the water tank in a manner that results in the Coriolis effect increasing the flow rate of water through the tubes. 12. The method of claim 7 further comprising providing hot water from the water tank for external use through a hot water tank outlet wherein the hot water tank outlet is coupled to the heated waxer tank inlet. 13. The method of claim 7 wherein the step of removing relatively cold water from the water tank further comprises removing relatively cold water from the water tank from a tank sediment drain.
