Definitions
- the invention relates to a method for controlling a water heater according to the preamble of claim 1.
- the point in time of the start of charging or Heating of the stratified storage by lowering the temperature of the content of the Storage determined below a predetermined temperature.
- the aim of the invention is to propose a method of the type mentioned at the outset can be carried out in practice with only a small outlay on equipment.
- the proposed measures make it possible to use a single one Temperature sensors to find the end, since ultimately only an exceeding the Temperature at any point of a run over the stratified storage Water cycle needs to be recorded.
- the memory is at least activated during each of the selected switch-on times cooled to a certain extent u. between both through radiation losses, as also by tapping, so that reheating even when using a corresponding one Sensor would have taken place.
- Another object of the invention is a device for performing the method to propose.
- the temperature sensor is only used as a switch-off sensor, which is used when a certain limit is exceeded Temperature ends charging.
- the features of claim 4 have the advantage that the achievement of a full charge of the stratified storage can be detected exactly.
- the features of claim 5 have the advantage that in addition to heating at a specified point in time, intermediate heating if the temperature is too high Unloading is possible due to an unusually strong tap. Such will be triggered when the temperature in the central area of the memory is below one predetermined value decreases. This creates a very high level of comfort for the user ensured.
- the water heating device has a store 1 operated as a stratified store, which is provided with insulation 25 on all sides.
- a cold water drain 4 leads from the lowermost area 26 of the store 1 to a heat exchanger 6 leads. Furthermore, a cold water inlet 2 opens into the bottom Area of the memory 1. In the cold water drain 4, a pump 5 is provided, which for a corresponding circulation of the water ensures.
- a hot water inlet 7 leads from the heat exchanger 6 into the uppermost region 27 of the storage 1.
- a hot water pipe 3 leads away from this uppermost area.
- a temperature sensor 12 is arranged, which when charging of the memory 1 detects the temperature of the incoming hot water.
- a temperature sensor 14 is arranged in the lowest area of the memory 1.
- the temperature sensor 14 is connected to a controller 10 via a signal line 24, which also has a switching timer 11. This sensor 14 delivers when one is exceeded predetermined temperature a signal that indicates the full charge of the memory and ended this by means of the control.
- the temperature sensor 12 is also connected to the controller 10 via a signal line 22 connected. This controls a motor of the pump 5 and the via a control line 21 Acting on the primary branch 6 'of the heat exchanger 6 via not shown Control devices of a water heater.
- control 10 or its switching timer 11 delivers a signal to start charging
- the controller 10 emits a signal to start the pump 5 via the control line 21, wherein the heat exchanger 6 is acted upon at the same time Primary branch 6 'is applied.
- Cool water is drawn off from the lowermost region 26 of the reservoir 1 and conveyed to the heat exchanger 6 and heated there.
- the warm water flows in the uppermost area 27 of the memory 1. Reaches the temperature in the range of Sensor 14 a certain value, this emits a signal, and the controller 10 ends the charging of the memory 1, the pump 5 being stopped and the Actuation of the primary branch 6 'of the heat exchanger 6 is ended.
- cold water overflows the cold water inlet 2 and in the lowermost area 26 of the reservoir 1.
- the delivery rate of the pump 5 can be carried out by the controller 10 in such a way that this is chosen so that the temperature of the outflowing process water is sufficiently high.
