Method and system for cooling of a device

A system for cooling a device, the system comprising:

• a first device configured to generate a first heat flow dependent upon operation and the first device is a potable water supply;
• a space surrounding the first device and configured to absorb the first heat flow;
• a second device which differs from the first device, the second device configured to generate a second heat flow, and the second device being a data center;
• a second space surrounding the second device, the second space separate from the space, and the second device is thermally isolated from the second space;
• and
• a thermal conduction system which thermally couples the second device and the first device to cool the second device and which is configured to conduct the second heat flow to the first device via a heat exchanger disposed between the first device and the second device, wherein no fluid which flows within the thermal conduction system is compressed or expanded,
• wherein the potable water supply is configured to absorb the second heat flow and an operating power of at least one water heating system associated with at least one consumption point of the potable water supply is automatically reduced based on the absorbed second heat flow.
