  • pre-assembled and tightness-tested assembly
  • high-grade, robust mixer
  • virtually any standard pump can be installed without reworking of the insulation
  • easy, fast mounting
  • sophisticated wall mounting kit
  • cable routing integrated in insulation

Heating pump assembly for use in mixed heating circuits. With the 3-way mixer and the actuator, the flow temperature can be adjusted to a desired temperature by adding water from the return. The new mixer with adjustable flow coefficient Kvs offers the HVAC professional maximum flexibility in adapting the system to individual control requirements. The flow coefficient Kvs can be modified at any later point in time, even if the system is under pressure. This way, a great variety of mixer/pump assemblies can be covered with a single version. PrimoTherm® 180-2 is also available as version RTA. It can be used to increase the return temperature with solid fuel burners which have a controller for increasing the return temperature.

Complete, pre-assembled and tightness-tested heating pump assembly with all required functional components, form-fit insulation.
