The present invention relates to a device for adjusting the heating power of a hot water generator comprising several heating elements Ra, Rb ... Rf, a programmer acting selectively on contacts connected to the said elements, this generator being included in an electrical installation comprising a priority circuit comprising at least one sensor D, characterised in that it comprises, in combination: - means for defining the heating rate of the generator by selecting the number of elements Ra ... Rf which must remain in service and - on opening the contact of the said sensor D of the priority circuit, means for controlling the programmer of the generator until it applies power to or keeps power applied to the said selected elements Ra ... Rf such that load-shedding of the installation is carried out on only a portion of the heating elements of the hot water generator. <IMAGE>
