A water heater is provided by a refrigerant cycle, in which the gas cooler is utilized to heat the water. A drain is incorporated into a water circuit for draining all of the water outwardly of the circuit when the system is shut down. In a preferred embodiment, a water outlet of the gas cooler is at the vertically lowermost portion of the water circuit. A drain valve is placed in this vertically lowermost location such that the water can be easily drained.

What is claimed is: 1. A system for heating water comprising: a refrigerant cycle including a compressor for compressing refrigerant and delivering compressed refrigerant to a first heat exchanger, an expansion device downstream of said first heat exchanger, and a second heat exchanger downstream of said expansion device, refrigerant passing from said compressor to said first heat exchanger, to said expansion device, to said second heat exchanger, and then returning to said compressor; a water circuit for passing water to be heated through said first heat exchanger, such that it can be heated by refrigerant in said first heat exchanger; and a drain for draining water at a location adjacent to said first heat exchanger from said water circuit, said drain being operable for draining water from said first heat exchanger, at least said first heat exchanger being positioned in an outdoor environment. 2. The system as set forth in claim 1, wherein water flows to said first heat exchanger from a storage tank, and is heated in said first heat exchanger and returned to said storage tank. 3. The system as set forth in claim 1, wherein said drain is a drain valve located at a vertically lowermost location on said water circuit. 4. The system as set forth in claim 1, wherein a water outlet of said first heat exchanger is said vertically lowermost location on said water circuit. 5. The system as set forth in claim 1, wherein said drain is positioned remote from a storage tank for receiving water downstream of said first heat exchanger, said drain being positioned to also drain said storage tank. 6. The system as set forth in claim 5, wherein said drain is positioned closer to said first heat exchanger than to said storage tank. 7. A system for heating water comprising: a refrigerant cycle including a compressor for compressing refrigerant and delivering compressed refrigerant to a first heat exchanger, an expansion device downstream of said first heat exchanger, and a second heat exchanger downstream of said expansion device, refrigerant passing from said compressor to said first heat exchanger, to said expansion device, to said second heat exchanger, and then returning to said compressor; a water circuit for passing water to be heated through said first heat exchanger, such that it can be heated by refrigerant in said first heat exchanger; and a drain for draining water at a location adjacent to said first heat exchanger from said water circuit, said drain being operable for draining water from said first heat exchanger, said drain being operable to drain the entire water circuit when opened. 8. The system as set forth in claim 7, wherein said first heat exchanger is positioned in an outdoor environment. 9. The system as set forth in claim 7, wherein water flows to said first heat exchanger from a storage tank, and is heated in said first heat exchanger and returned to said storage tank. 10. The system as set forth in claim 7, wherein said drain is a drain valve located at a vertically lowermost location on said water circuit. 11. The system as set forth in claim 7, wherein a water outlet of said first heat exchanger is said vertically lowermost location on said water circuit. 12. The system as set forth in claim 7, wherein said drain is positioned remote from a storage tank for receiving water downstream of said first heat exchanger. 13. The system as set forth in claim 7, wherein said drain is positioned closer to said first heat exchanger than to said storage tank.
