Abstract

1. Hot water heating plant comprising a hot water generator including a heat source designed to be energised electrically by means of a control circuit, a heating loop including a forward duct, heaters and a return duct, temperature controlled heater valves provided at said heaters and designed to adjust the flow rate of water through the respective heater as a function of room temperature and of respective set points as set at the respective heater valves, a circulation pump interposed intermediate said hot water generator and said forward duct and comprising a pressure difference controller interconnected intermediate said forward duct and said return duct and including an overflow valve, a short-circuit connection connected in parallel to said heaters being adapted to be cleared, when a predetermined response point is exceeded, to a higher or lower degree by means of said pressure difference controller as a function of the pressure difference existing between said forward duct and said return duct, a first switch contact (56) is provided in said plant at said pressure difference controller, said switch contact (56) being closed when said overflow valve is closed and being opened when the same opens and being connected in said control circuit of said heat source, characterised in that a second switch contact (58) provided at the pressure difference controller is connected in series with the first switch contact (56) and opens at a lower pressure difference than said first switch contact (56) and that a bridging contact controlled by means of a time switch (62) is connected in parallel to said second switch contact (58).
