Definitions

  • the invention relates to a hot water tank with a thermostat arranged in the central or upper region of the storage space, which monitors the temperature of the tap water to be drawn, and a thermostat arranged in the floor area of the storage space, which monitors the temperature below this limit in this floor area Heating.
  • Such a hot water tank has become known from DE-OS 3 346 513.
  • a heat pump is used to heat the tank, and switching between the two sensors is carried out in order to either heat a small amount of water at a high temperature when there is little hot water or an increased amount when there is a large amount of water To be able to provide water.
  • a gas-heated hot water tank has become known, which can both store service water and can give off heat to the circulating water of a heating system.
  • the motor of a circulation pump of the heating system is acted upon by a temperature sensor, which senses the interior of the store.
  • a temperature sensor which senses the interior of the store.
  • a second temperature sensor that controls the heating of the storage tank.
  • a directly heated hot water tank has become known from DE-OS 3 310 023, in which three temperature sensors are provided which control the heating of the tank in connection with an automatic burner control.
  • the object is achieved according to the invention in that the lower thermostat is coupled to a timer which only switches on the heating of the storage water if within a predetermined period of time no heating controlled by the thermostats arranged in the middle or upper area of the storage space has occurred.
  • This configuration makes it possible to query within selectable periods of time whether the store has been reheated. If this has not happened, the heating is released via the timing element in such a way that the entire contents of the memory are heated to a temperature which ensures that the bacteria are killed.
  • the only drawing figure shows a schematic vertical section of a storage tank 1 with a raised floor 2.
  • the flow line 4 of a burner-heated water heater not shown, opens, the hot water of which flows through the storage space 3 for heating the storage water in a coil 5 and then flows back to the water heater in the return line 7 passing through the storage ceiling 6.
  • a cold water supply line 8 also passes through the storage ceiling 6 and opens into the floor area of the storage space 3.
  • a hot water supply line 9 extends from the storage ceiling 6.
  • a thermostat 10 is - as usual - arranged in the middle or upper area of the storage space 3. If the temperature falls below a threshold value, he switches the heating of the storage water through the coil 5 flowing hot water, and switches off the heating when an upper limit is reached.
  • the lower additional thermostat 11 in the floor area ensures that the water temperature in this floor area does not drop too long, allowing a development of microorganisms below a threshold value that enables development.
  • this thermostat 11 can be coupled to a timer which only causes heating of the storage water controlled by this thermostat 11 if no heating controlled by the upper thermostat 10 has occurred within a predetermined period of time.
