Definitions

  • the invention relates to a hot water heater with a storage tank through which water flows, with a cold water inlet in the lower tank area and a hot water outlet in the upper tank area, and with a heating element arranged in the storage tank.
  • a storage hot water heater with a lower hot water inlet and an upper hot water outlet and a heating control thermostat is known, for the purpose of rendering harmless of bacteria present in the water, the thermostat is arranged in the upper area of the storage tank and is set to a switching temperature of 80 ° C.
  • This measure is intended to ensure that in the upper region of the storage tank, the hot water in this zone is guaranteed to be heated to temperatures of around 80 ° C. at which the harmful bacteria are killed.
  • the heating of all escaping process water to values around 80 ° C can be counteracted by the problem of bacterial multiplication, but this solution is not suitable for the large number of low-temperature systems in use, and it does not prevent the multiplication of bacteria in sludge deposits in the Bottom area of the process water tank, so that there is still the risk of bacteria infiltrating the process water if, for example, the temperature in the upper tank area drops significantly due to a fault.
  • a water reservoir which has in its lower region a water inlet directed towards the bottom of the water reservoir, a heating element arranged above the water inlet and a water outlet arranged in the upper region of the water reservoir.
  • the object of the invention is to avoid the formation and multiplication of bacteria, in particular Legionella, in a hot water heater of the type specified by simple measures which do not require any additional energy expenditure and, above all, to exclude the dangers arising from deposits and sediment formation in dead spaces.
  • a hot water heater with a storage tank through which water flows a cold water inlet in the lower tank area, a hot water drain in the upper tank area, a heating element arranged in the storage tank and a cold water drain in the lower tank area is used in such a way that all cold service water is removed from the cold water drain in the lower tank area during operation.
  • the cold water inlet is directed to the bottom of the storage tank by means of a pipe bend in the lower tank area, a deflection part being arranged in front of the outlet opening of the cold water inlet.
  • the cold water drain is then preferably arranged below the deflection part on the bottom of the storage container.
  • the heating element is arranged above the lower container area.
  • the endangered tank area 1 Due to the arrangement of the cold water inlet 4 and the cold water outlet 5 in the lower tank area 1, the endangered tank area 1 is always rinsed with fresh water and flows through, so that no sludge formation can occur.
  • the cold water inlet 4 is formed by a curved tube which opens out as a deflection part 3 in relation to a baffle plate. In this way, a particularly effective flushing of the end of the container at risk is ensured.
  • the total amount of cold water used is routed through the hot water heater shown, but at the same time the hot water is also generated.
  • the pressure level in the cold water area and in the hot water area is the same, which means fluctuating mixing temperatures at the consumer can be avoided.
  • the hot water heater covered with insulation 10 is equipped in the usual way with a thermostat 9, which makes it possible to regulate the hot water temperature to the desired value, in particular to about 60 °.
  • a thermometer 8 is provided in the usual way for visual checking of the respective temperature.
