1. A system for heating a body of liquid, the system comprising: a cylindrical housing having a bottom surface, an upper lid, and at least one attachment point;a cylindrically coiled heated line having an inner coil, an outer coil disposed within said cylindrical housing, the cylindrically coiled heated line having heated fluid traveling therethrough for heating the liquid that is in contact with an external surface of the cylindrically coiled heated line;a first port connected to and extending vertically from said outer coil and through the upper lid of said cylindrical housing;a second port connected to and extending vertically from said inner coil and through the upper lid of said cylindrical housing; andsaid cylindrically coiled heated line forming a continuous opening extending from said second port, through said inner coil, through said outer coil and to said first port. 2. The system for heating a body of liquid according to claim 1 where said first port is an outlet port. 3. The system for heating a body of liquid according to claim 2 where said second port is an inlet port. 4. The system for heating a body of liquid according to claim 3 further comprising a pump to deliver the heating fluid to said inlet port. 5. The system for heating a body of liquid according to claim 1 wherein said attachment point is sufficiently rigid to support the weight of said cylindrical housing, said cylindrically coiled heated line and any fluid therein. 6. A system for heating a body of liquid, the system comprising: a boiler for heating fluid, the boiler having a first line and second line;a cylindrical housing having a bottom surface and an upper lid;a cylindrically coiled heating line having an inner coil, and an outer coil disposed within said cylindrical housing, the cylindrically coiled heating line for heating the liquid that is in contact with an external surface of the cylindrically coiled heating line;a first port connected to and extending vertically from said outer coil and through the upper lid of said cylindrical housing and connected to said second line;a second port connected to and extending vertically from said inner coil and through the upper lid of said cylindrical housing and connected to said first line for receiving the heated fluid provided by the boiler;said cylindrically coiled heating line forming a continuous opening extending from said first port, through said inner coil, through said outer coil and to said second port. 7. The system for heating a body of liquid according to claim 6 where said first line is a supply line and said second line is a return line. 8. The system for heating a body of liquid according to claim 7 where said first port is an inlet port. 9. The system for heating a body of liquid according to claim 8 where said second port is an outlet port. 10. The system for heating a body of liquid according to claim 6 further comprising a pump to deliver a heating fluid to said inlet. 11. The system for heating a body of liquid according to claim 6 where said cylindrical housing further comprises at least one attachment point. 12. The system for heating a body of liquid according to claim 11 wherein said attachment point is sufficiently rigid to support the weight of said cylindrical housing, said cylindrically coiled heating line and any fluid therein. 13. A method for heating a body of liquid at risk of freezing or forming ice, comprising the steps of: placing a cylindrical housing in the body of liquid at risk of freezing such that the cylindrical housing is at least partially submerged therein, said cylindrical housing having a bottom surface, an upper lid, at least one attachment point and a cylindrically coiled heating line having an inner coil and an outer coil disposed therein, including contacting the body of liquid with an external surface of the heating line;connecting a first line of a boiler to a first port of the heating line that is connected to and extends vertically from said outer coil and through the upper lid of said cylindrical housing;connecting a second line of the boiler to a second port of the heating line that is connected to and extends vertically from said inner coil and through the upper lid of said cylindrical housing; andpumping heated fluid from said boiler and through a continuous heating passage comprising said second line, said second port, said inner coil, said outer coil, said first port and said first line for heating the body of liquid that is in contact with the external surface of the heating line. 14. The method of claim 13 where said first line is a return line, said second line is a supply line, said first port is an outlet port and said second port is an inlet port. 15. The method of claim 13, further comprising attaching a crane to the at least one attachment point and hoisting the cylindrical housing including the cylindrically coiled heating line therein.
