A solar heat plant is serving the purpose of heatening utility water, which is to be used, for example, for personal hygiene or cosumption. The plant comprises a solar collector (1) for the collecting of the incident solar radiation energy; an accumulator (2) for the accumulation of the received energy; a first liquid cycle (7) for the circulation of a heat carrying liquid (4) between the solar collector (1), where the liquid absorbs the solar energy in the form of heat, and the accumulator (2) where the liquid gives off the heat; and a second liquid cycle (16) to lead the utility water for heatening to the accumulator (2) and hot utility water from this to the place of use. The accumulator (2) consists ofa container (2) which is filled with the heat carrying liquid (4) and inserted in the first liquid cycle (7). The plant also comprises a heat exchanger (13) as well as a third liquid cycle (19) for the circulation of the heat carrying liquid (4) between the accumulator (2) and one of the sides (14) of the heat exchanger (13), while its other side (15) is inserted in the second liquid cycle (16). The utility water will consequently not be in contact with the liquid (4) in the accumulator (2) and will therefore not be infected with bacterias as is the case in conventional plants, which as accumulator use a hot-water tank containing the hot utility water and notoriously can be a hotbed for bacterial cultures. Consequently, it is not unhygienic and injurious to health to use the solar heat plant according to the invention, as is the case with the conventional solar heat plants.
