HeatBloC mixed heating circuit without pump

Pump group for flexible integration of mixed heating circuits.

If you are designing a heating system where a circulation pump is already installed, or you want to use a specific pump, this heating circuit module is the ideal solution. The pre-assembled unit with 3‑way mixing valve and adjustable bypass can be precisely matched to mixed heating circuits, allowing you to control the flow temperature accurately – whether for radiators or underfloor heating.

The integrated thermometer ball valve, gravity brake and flexible thermal insulation provide an installation-friendly, easy-to-service solution with minimised heat losses. The prepared pump connection gives you full freedom to select or retrofit the appropriate high-efficiency pump.

Ideal for systems with multiple temperature zones, both in new-builds and renovation projects.
