TacoSol Circ ER HE

Pump assembly with high-efficiency pumps, balancing valve and optional safety subassembly for solar heating energy systems.


Hydraulic balancing and flow measurement can be carried out directly on the station in the case of the TacoSol Circ ER HE solar station. The integrated TacoSetter Inline 130 allows the volume flow in the primary circuit to be precisely and conveniently adjusted and checked. Systems that are correctly balanced hydraulically ensure optimal energy transfer from the collector panel to the heat storage unit and therefore allow economical operation of the solar system.
Using scales that are pre-calibrated for inhibitors, specialists locally can adjust and check the flow values. Training and costly measuring devices are no longer needed.



  • Equipped with all the necessary valves and components


  • Hydraulic balancing and functional checking of the system with TacoSetter Inline 130
  • Pump can be changed with ease as it is lockable on the intake and output sides
  • Simple filling, draining and servicing of the system owing to multifunctional ball valve


  • Highly efficient system operation owing to permanent air separation with use of HE pumps


  • Flexibility thanks to the option of integrating control systems


In combination with a solar controller, the solar station transports the solar liquid heated in the collector to the hot water/drinking water storage tank via a heat exchanger.
The integrated TacoSetter Inline 130 balancing valve enables the volume flow to be adjusted to the performance of the collector or heat exchanger and checked.
The flow measurement of this balancing valve is based on the principle of a float. The regulating screw on the flow meter is used to adjust the flow. The reading position is the lower edge of the float element.
