Definitions

  • the amount of heat supplied to the water flowing through the instantaneous water heater is regulated as a function of the temperature of the water flowing out of the instantaneous water heater and the drawn hot water quantity, that is to say on the hot water side.
  • electronic instantaneous water heaters are so-called electronic instantaneous water heaters.
  • the energy supplied to the heating device is regulated down until the temperature of the water leaving the instantaneous water heater has dropped to the setpoint temperature.

  • a mechanical switching element so that when a high hot water demand switching to a high power level occurs and so the water supplied heat and to increase the energy supplied to the heater.
  • switching to a low power level occurs, so that the energy supplied to the heater and thus also the amount of heat supplied to the water is reduced.
  • the flow measurement is usually carried out in such flow heaters in the flow area, ie cold water side. Furthermore, the control of the energy supplied to the heating device or the amount of heat supplied to the water takes place at discrete switching levels, ie is not continuously increased or reduced with the flow rate, but only for different flow intervals, d.
