A liquid-cooled computing and
heating system for integration into the building services of buildings, comprising at least one liquid-cooled computing unit, a primary cooling circuit for dissipating thermal power losses from the computing unit, a
heat pump for raising the temperature level of these power losses, and a secondary heating circuit, characterized in that the computing and
heating system is designed as a pre-assembled, plug-and-play
modular system from modularly combinable functional units, wherein the secondary heating circuit is fluidically connected to a topologically variable buffer storage arrangement, which is designed as a thermal
cascade consisting of at least two separately installable storage tanks connected in series, wherein at least one of the storage tanks has at least one integrated
electric heating element.and wherein an upper
storage area, maintained at a specific temperature, primarily feeds a
fresh water station for hygienic, continuous domestic hot
water heating, and a lower
storage area, maintained at a specific temperature, serves as a hydraulic cooling zone for the return flow of a space heating circuit, and wherein the
system has an automated, control-controlled bypass
system which, when the buffer storage arrangement is thermally saturated, diverts the
power loss of the computing unit to an external
waste heat unit, completely bypassing the
heat pump, in order to ensure
continuous operation of the computing unit that is decoupled from the building's heat demand.
