SKE Distribution Low-Loss Headers (Hydraulic Balancers) – Basic Versions

Function and Application

The SKE distribution low-loss header, also known as a hydraulic balancer, is designed to hydraulically separate the boiler circuit from the heating circuit. It is primarily used in medium- and high-power heating systems (starting from 25 kW and typically from 40 kW upward), which may include:

  • One or more boilers (solid fuel, gas condensing, or heat pump-based)

  • Multiple heating zones or circuits (e.g. underfloor heating, radiator heating, and domestic hot water (DHW))

In such complex systems, the SKE eliminates the need for manual flow balancing between pumps. It allows each circuit to operate independently and without interference, ensuring optimal pump performance and stable hydraulic conditions.


Key Features

  • Hydraulic Separation: Enables independent operation of boiler and heating circuits, preventing mutual pump interference.

  • Integrated Desilter and Air Vent: Enhances system reliability by removing sludge and air from the circuit.

  • SMART Magnetic Separator: A built-in neodymium magnet captures fine magnetic particles, preventing corrosion and rust caused by circulating debris.

  • Boiler Protection: Prevents low return water temperature to solid fuel boilers (avoiding condensation and corrosion).

  • Flexible Installation: The unit can be installed in any orientation, adapting to site-specific requirements.


Operating Scenarios

  1. Heat Demand = Boiler Output
    The system operates under equilibrium. Boiler output matches the heating circuit demand.

  2. Heat Demand < Boiler Output
    When thermostatic valves (e.g. on radiators) begin closing, excess heat circulates back through the hydraulic balancer. This signals the boiler to reduce output or shut down.

  3. Heat Demand > Boiler Output
    Increased suction from the heating circuit through the balancer signals the boiler to increase power to meet demand.
