This is a modern, cost-effective solution for heating systems using Low Loss Headers (also known as Hydraulic Balancers). These components help optimize the operation of multi-boiler and multi-circuit heating systems by separating boiler circulation from heating circuits, thereby enhancing efficiency and system longevity.

Key points:

• Compatibility: All headers are tested for pressurized systems up to 10 bar.
• Functions: They balance flows automatically and incorporate desilter and air vent functions.
• Operation Modes: The balancer adjusts its operation based on the heat demand relative to the boiler’s output:
  • When heat demand equals boiler output, it maintains a stable flow.
  • If the demand is less, it signals the boiler to decrease power or switch off.
  • If the demand exceeds the boiler’s output, it signals the boiler to increase power.
• Model Example (SHE 1"):
  • Max flow: 2.3 m³/h
  • Max power: 40 kW
  • Temperature tolerance: up to 110°C
  • Pressure: 10 bar
  • Capacity: 1 liter

Advantages for investors:

• Up to 30% longer boiler service life due to protection from low return water temperature
• Increased operational comfort thanks to system desilting and aeration
• Up to 30% longer pump service life due to undisturbed mutual operation
• Quicker boiler response
• Up to 50% cost savings compared to 3- or 4-way valves

Advantages for installers:

• No system regulation needed due to automatic pump operation
• Reduced claims caused by improper system operation or air locking
• Automatic operation simplifies installation and maintenance

Available variants:

• SHE – LLH: Power ranges from 40 to 420 kW
• SHE-OC: Insulated versions (PUR foam + leatherette coating), powers from 40 to 115 kW (models with 225 and 420 kW can be insulated with ROCKWOOL if requested)
• SHE-SP: Balancers with stainless steel replaceable air separators, powers from 25 to 209 kW

Summary: Using Low Loss Headers (Hydraulic Balancers) provides a reliable, efficient, and economical solution for heating systems—contributing to longer system lifespan, improved comfort, and cost savings.

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.

Available Models and Applications

Why Choose the SKE Hydraulic Balancer?

• Simplifies multi-circuit system design and commissioning

• Enhances system longevity and efficiency

• Reduces maintenance through built-in magnetic filtration and air removal

• Compatible with modern high-efficiency boilers and heat pumps

• Modular models available for varying system sizes and configurations

Low-Loss Header, also known as a Hydraulic Balancer, is designed to separate the boiler’s circulation from the heating system, suitable for medium to high-power systems (25 kW and above, ideal for an average house). It is used in setups with one or more boilers and various heating circuits, such as floor heating, radiators, or hot utility water. The LLH automatically manages flow separation, eliminating the need for manual balancing of pump flows. Its construction includes a desilter and air vent, offering additional benefits of system cleaning and air removal while protecting the boiler from low-temperature corrosion of the return water.

Operational Modes:

1. When the heat requirement equals the boiler’s power, the system operates in balance.
2. If the requirement is less than the boiler’s capacity (e.g., thermostatic valves are closed), some heat returns from the LLH, signaling the boiler to decrease output or switch off.
3. If the requirement exceeds the boiler’s capacity, increased pump suction signals the boiler to produce more heat.
