Definitions

the invention relates to a domestic water heater according to the preamble of the claim 1.
the NTC resistance is in the cold water supply arranged and is therefore very directly exposed to the influence of the incoming cold water.
This also has the disadvantage that the NTC resistance is already the lowest Tap quantities, such as those that occur through a leaky tap can, responds or recognizes these small amounts as tapping and therefore starts the heating device of the domestic water heater. Because the intended Switch-off temperature of the hot water heater, which is conveniently a storage tank has been reached very quickly, the heating device is quickly switched off again. At such operation, however, results in correspondingly high losses, and at Using a burner as a heater also has the disadvantage that it there is a correspondingly high emission of pollutants.
the aim of the invention is to avoid the disadvantages outlined at the beginning and one To propose hot water heater of the type mentioned, in which a start of the Heating device is avoided due to only very small draw quantities.
the proposed measures ensure that very small taps, such as occur with a leaky tap, can not be detected and the NTC resistor does not respond to such, so that no activation of the Heating device is carried out.
a domestic water heater that is equipped with a Heating water heater is coupled, for example via a arranged in the memory Secondary heat exchanger, the appropriate heat from the heating water circuit to be covered.
the features of claim 3 ensure that the tap is smaller Flow of the inflowing cold water that forms the quantities of process water is sufficient, to reach the wall opposite the cold water inlet and the outside wall Cool NTC resistor. It is sufficient if only a relatively small one Part of the opening cross-section of the tap is released to the tap through the Detect NTC resistance and initiate the activation of the heating device. On the other hand but it is also ensured that the resulting valve tap Cold water flow is not sufficient to cool the NTC resistor, so that he cannot record such a tap.
a domestic water heater 1 has a Plate heat exchanger 2, which is used to heat the contents of the domestic water heater 1 serves.
This plate heat exchanger 2 is with a heating water inlet 6 and one Provide heating water outlet 7.
the hot water heater 1 is provided with a cold water inlet 3, which is inside the Domestic water heater 1 is designed as a nozzle 4. Furthermore, the domestic water heater 1 provided with a hot water outlet 5.
a temperature-dependent resistor 8 (NTC or PTC resistor) arranged close to the hot water heater 1, the a good heat-conducting material is made.
the NTC resistor 8 is usually activated by means of a control, not shown kept at a certain temperature. If there is a tap of domestic water, cold water then flows in, hitting the one opposite the cold water inlet 3 Wall 9 of the hot water heater 1 and therefore cools the NTC resistor, whereby this changes its resistance value. As a result, a tap is recognized, and the heater, which is formed by the plate heat exchanger 2, is activated.
the flow rate is incoming cold water too low to the cold water inlet 3 opposite To reach wall 9 of the hot water heater 1, so that the NTC resistor 8 this Inflow of cold water can not capture. This prevents activation of the Heating device, and it also increases the efficiency of the hot water heater reducing start-stop operation of a burner of the heating device, the heated one Water passes through the plate heat exchanger 2 via connections 6 and 7, with short Operating times avoided.
