  • Such type pumps usually operate in continuous operation.
  • heating circulation pumps for the purpose of e- nergieeinsparung via a manually operable and often connected to the heating circulation pump control several, mostly 3, set different speeds and thus influence the funded flow in the heating circuit and energy consumption. In general, this is done by switching parts of the stator winding via taps on it.
  • heating circulation pumps have a number of disadvantages.
  • a pump used in continuous operation also promotes medium even if there is no heat requirement at all and above all no decrease in heat quantities.
  • heating circulating pumps are also subject to cavitation during operation, it is generally recommended by installers to always select the lowest flow and lowest power among the manually selectable settings. This des- half, so that cavitation kept low and ultimately the life of the heating circulation pump is increased.
  • the continuous operation creates an unnecessary need for electrical energy.
