A computer-implemented method monitors and/or controls domestic hot water production and/or distribution. The method includes detecting at least two real temperatures of a fluid stored in a heat storage tank at two different positions along a height of the heat storage tank at least at points in time, and acquiring a temperature distribution pattern of heat stored in the heat storage tank and/or corresponding heat distribution pattern data by applying a temperature-distribution-pattern-algorithm to the detected real temperatures detected at the points in time. The fluid is sanitary hot water, and the heat storage tank is a pressurized tank. A computer may carry out the method. The computer may be part of a system. A computer program may include instructions to cause the controller of to execute the method. The computer program may be stored on a computer-readable medium.

Provided is a hot and cold water mixer capable of performing stable temperature control, including a cold water supply pipe, a hot water supply pipe, a mixing pipe, flow rate adjustment valves, temperature sensors, flow rate sensors, a setting unit, and a control unit.
