ELTERM Condensing Low-Loss Header (SHE CD 1")

Modern solution for your heating system – reliable, efficient, and cost-effective!
!!! ALL HEADERS ARE TESTED FOR PRESSURISED SYSTEMS UP TO 10 BAR !!!

Condensing Low-Loss Headers feature a stainless steel flow guide, which lowers return water temperature by 2–5°Ccompared to traditional low-loss headers. This improves the efficiency of condensing boilers or heat pumps, maximizing energy savings.

Overview

The Low-Loss Header (Hydraulic Balancer) separates boiler circulation from heating circuits, making it ideal for medium- and high-power systems (from 25 kW). It supports multiple boilers and heating circuits, such as:

  • Floor heating

  • Radiator heating

  • Domestic hot water

Key Features

  • Independent pump operation: Eliminates the need for manual flow balancing

  • Desilter & air vent functions: Enhance system cleaning, aeration, and reliability

  • Boiler protection: Prevents low-temperature corrosion by maintaining optimal return water temperatures

Operational Modes

  1. Heat demand = Boiler output: System is balanced

  2. Heat demand < Boiler output: Part of the heat returns, signaling the boiler to reduce output or switch off

  3. Heat demand > Boiler output: Pump suction increases, signaling the boiler to generate more heat

Operation is fully automatic, requiring no adjustments.
