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: 1.8 m³/h
  • Max power: 28 kW
  • Temperature tolerance: up to 110°C
  • Pressure: 10 bar
  • Capacity: 1 l.

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 28 to 420 kW
• SHE-OC: Insulated versions (PUR foam + leatherette coating), powers from 28 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.

SHE Hydraulic Separators – Headers for Central Heating Systems

A properly designed central heating system should deliver reliable, efficient, and energy-saving performance for many years. One of the key components responsible for achieving these results is a hydraulic separator. This essential element is widely used in both modern and upgraded heating installations, ensuring the stable and efficient operation of the entire system.

SHE hydraulic separators are suitable for heating systems powered by solid fuel boilers, condensing boilers, and heat pumps. In solid fuel boiler installations, they effectively protect the boiler against excessively low return water temperatures, helping to extend the service life of the heating equipment and improve its reliability.

What Is the Purpose of a Hydraulic Separator?

The primary function of a hydraulic separator is to hydraulically separate the heat source circuit from the heating distribution circuit. This allows flow rates and pressure differences between the individual circuits to be balanced, enabling each circuit to operate independently and efficiently.

Hydraulic separators are particularly beneficial in installations where the required flow rate on the heat source side differs from that of the heating system. They are also an excellent solution for underfloor heating systems, where the temperature difference between the supply and return water is relatively small.

Hydraulic separators are commonly used in:

• systems with wall-mounted boilers equipped with integrated circulation pumps,
• compact heating units with a low water volume,
• heating systems featuring multiple heating circuits.

By maintaining the correct water flow rate, a hydraulic separator effectively separates the boiler circuit from the heating circuit, resulting in improved system stability, enhanced operating efficiency, and greater user comfort.

Why Choose low loss headers from Culm Stores Distribution Elterm Ltd?

SHE hydraulic separators are premium-quality products designed to ensure efficient operation in a wide variety of central heating systems. Available in six different sizes, they can be easily matched to the requirements of virtually any installation.

Depending on the model, the separators are manufactured from high-grade stainless steel (INOX) or carbon steel protected with a durable powder-coated finish that provides excellent corrosion resistance and long-lasting durability.

All SHE hydraulic separators feature a universal connection spacing compatible with Elterm 2D+ and 3D+ distribution manifolds. Standard equipment includes:

• an automatic air vent,
• a drain valve,
• a robust, durable construction designed for long service life.

Selected models are additionally equipped with a flow guide that reduces the recirculation of hot water directly back to the heat source, improving the overall efficiency of the heating system.

Benefits of Using SHE Hydraulic Separators

Installing a SHE hydraulic separator offers numerous advantages, including:

• balancing flow rates and pressure within the heating system,
• improving the overall efficiency of the installation,
• reducing the risk of air accumulation within the system,
• ensuring smooth operation of multiple heating circuits,
• extending the service life of boilers and circulation pumps,
• providing safe, reliable, and efficient operation of the entire central heating system.

SHE hydraulic separators are a proven solution for professional installers and end users looking for high-quality workmanship, reliable performance, and seamless integration with modern heating systems.
