An apparatus for preparing a beverage from water and an instant product includes a water supply system for supplying water, a heating device for sterilizing water by heating it; and a cooling device for cooling water heated in the heating device. The cooling device uses water from the water supply system as cooling-water. The water that is sterilized in the heating device has preferably previously been used in the cooling device as cooling-water. The cooling device includes a counter flow heat exchanger.

1. An apparatus for preparing a beverage from water and an instant product, the apparatus comprising: a water supply system for supplying water to a cooling device;a heating device for sterilizing water supplied from the cooling device by heating the water supplied from the cooling device; anda mixing unit for mixing the instant product with the sterilized water, wherein an outlet of the heating device is connected to an inlet of the cooling device and an inlet of the mixing unit,wherein the cooling device is configured to cool water that has been heated in the heating device; and wherein the cooling device uses water from the water supply system as cooling-water, andwherein a first outlet of the cooling device is connected to an inlet of the heating device, and a second outlet of the cooling device is connected to the mixing unit. 2. The apparatus according to claim 1, wherein the cooling device and the heating device are arranged such, that heat withdrawn from the water in the cooling device is used to preheat water supplied to the heating device. 3. The apparatus according to claim 1, wherein the cooling device and the heating device are arranged such, that water from the water supply system, before being fed into the heating device for sterilization, is used in the cooling device as cooling-water. 4. The apparatus according to claim 1, wherein the cooling device comprises a counter flow heat exchanger. 5. The apparatus according to claim 4, wherein the counter flow heat exchanger comprises a first tube, surrounded by a second tube, which tubes are wound into a spiral. 6. The apparatus of claim 4, wherein a hot water inlet of the heating device and a cold water outlet of the cooling device are located near a center of the spiral, and a hot water outlet of the heating device and a cold water inlet of the cooling device are located near an outer circumference of the spiral. 7. The apparatus of claim 4, wherein a hot water inlet of the heating device and a cold water outlet of the cooling device are located near an outer circumference of the spiral, and a hot water outlet of the heating device and a cold water inlet of the cooling device are located near a center of the spiral. 8. The apparatus according to claim 1, wherein the heating device is arranged to sterilize water by heating said water at sterilization temperatures below 100° C., during a minimum time interval that increases with decreasing sterilization temperature. 9. The apparatus according to claim 8, wherein the heating device is arranged to heat the water at a sterilization temperature equal to or higher than 70° C. 10. The apparatus according to claim 1, furthermore comprising one or more safety provisions, for monitoring selected process parameters, and initiate an action when a threshold value is exceeded, wherein the action includes at least one of alarming a user, shut down the apparatus, and taking corrective action to bring the selected process parameters back to desired levels. 11. The apparatus according to claim 1, further comprising a bypass configured to allow heated water from the heating device to bypass the cooling device. 12. The apparatus of claim 4, wherein the counter flow heat exchanger comprises a first tube, surrounded by a second tube, which tubes are wound into a three-dimensional spiral. 13. A method for preparing a beverage from water and an instant product, the method comprising the acts of: supplying water from a water supply system to a cooling device;sterilizing water supplied from the cooling device by heating the water supplied from the cooling device using a heating device; andmixing the instant product with the sterilizing water to form the beverage;wherein the cooling device is configured to cool water that has been heated in the heating device and wherein the cooling device uses water from the water supply system as cooling-water, andwherein an outlet of the heating device is connected to an inlet of the cooling device and an inlet of the mixing unit, and wherein a first outlet of the cooling device is connected to an inlet of the heating device, and a second outlet of the cooling device is connected to the mixing unit. 14. The method of claim 13, further comprising the act of using heat withdrawn from the water in the cooling device to preheat water supplied to the heating device. 15. The method of claim 13, further comprising the act of using water from the water supply system in the cooling device as the cooling-water before feeding water from the cooling device into the heating device for sterilization. 16. The method of claim 13, wherein the cooling device comprises a counter flow heat exchanger. 17. The method of claim 16, wherein the counter flow heat exchanger comprises a first tube, surrounded by a second tube, which tubes are wound into a spiral.
