Low-Loss Header, also called a Hydraulic Balancer, is designed to separate the boiler’s circulation from the heating system, suitable for medium- to high-power setups (from 25 kW up to 420 kW). It’s used with one or more boilers and supports various heating circuits like floor heating, radiators, and hot utility water.

Key Functions and Benefits:

• Flow Separation: Automatically divides flow, allowing boiler and system to operate independently without manual balancing.
• Additional Features: Equipped with a desilter and air vent, which aid in system cleaning and removing air, enhancing efficiency.
• Protection: Prevents low-temperature corrosion by maintaining appropriate return water temperatures.

Operational Modes:

1. Heat demand = boiler output: System operates normally.
2. Heat demand < boiler output (e.g., thermostatic valves closed): Part of the heat returns, signaling the boiler to decrease or switch off.
3. Heat demand > boiler output: Pump suction increases, prompting the boiler to produce more heat.

Equipment Details:

Low Loss Header SHE 2.5" Flanges

• Max flow: 24 m³/h
• Max power: 420 kW
• Connectors: 4 x 2.5" flanges
• Nominal pressure: 10 bar
• Max temperature: 110°C
• Capacity: 19.7 liters

Advantages for Investors:

• Up to 30% longer boiler lifespan due to protection from low return water temperatures
• Increased comfort through system desiltering and aeration
• Up to 30% longer pump operation life
• Faster boiler response
• Up to 50% cost savings versus 3- or 4-way valves
• No system regulation needed
• Fewer system claims caused by air locking or improper operation

Variants Available:

• SHE – LLH: Power range from 40 to 750 kW
• SHE-OC: Insulated with PUR foam and leatherette; power from 40 to 156 kW (larger units up to 750 kW can be insulated with ROCKWOOL if requested)
• Summary:

This hydraulic balancer ensures efficient, reliable operation of heating systems, reduces maintenance, and prolongs equipment lifespan—offering long-term savings and peace of mind for system owners.

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.

Features of the Low Loss Header SHE 3”:

• Max flow: 24 m³/h
• Max power: 420 kW
• Connectors: 4 x 3" DN80 Flanges
• Nominal pressure: 6 bar
• Max temperature: 110°C
• Capacity: 27.5 l.
• Vent and drain valves included

Advantages for investors:

• Up to 30% longer boiler service life through protection from low return water temperatures
• Enhanced operational comfort via system desiltering and aeration
• Up to 30% longer pump service life due to smooth, undisturbed operation
• Faster boiler reactions to changing demands
• Cost savings of up to 50% compared to traditional 3- or 4-way valves

Advantages for installers:

• No need for complex system regulation, thanks to automatic flow management
• Reduced claims caused by air locking or improper operation

Variants Available:

• SHE – LLH: Power range from 40 to 420 kW
• SHE-OC: Insulated with polyprene shell, power from 40 to 156 kW (up to 420 kW can be insulated with ROCKWOOL upon request)
