Low Loss Header 2K PRO-Insulated

 Low Loss Header PRO 2K by Elterm is a professional hydronic system component used in central heating (CH) installations, underfloor heating systems, and domestic hot water (DHW) systems. They ensure proper and stable operation of heating systems and are manufactured by the Polish company Elterm, a well-known producer of heating equipment and hydronic accessories.

What is a low-loss header?

A low-loss header is a component that:

• Separates the boiler circuit from the heating circuits (e.g. radiators, underfloor heating, DHW tank),

• Allows independent operation of pumps in different circuits without the need to balance their flows,

• Stabilises flow rates and pressure in the system,

• Protects the boiler against too low return temperatures (reduces low-temperature corrosion),

• Facilitates air venting and dirt/sludge separation in the system.

What does “PRO” mean in Elterm low loss headers?

In Elterm’s product range, “PRO” denotes more advanced versions of SHE-PRO low loss headers, often equipped with additional features or improved insulation (e.g. EPP thermal insulation), and designed to work seamlessly with other system components such as KRE PRO manifolds.

Example models from the PRO series include:

• SHE-PRO up to 40kW - for heating systems up to 40kW

• SHE-PRO up to 70 kW – for heating systems up to approx. 70 kW,

• SHE-PRO up to 156 kW – for larger systems up to approx. 156 kW,

• SHE-PRO 2K – a version designed for two heating circuits or pump groups.

Main functions of Elterm PRO low-loss headers

✔️ Hydraulic separation – isolates the boiler side from the distribution side, preventing flow interference
✔️ Simplified pump cooperation – multiple pumps can operate without precise hydraulic matching
✔️ Air and sludge separation – improves system cleanliness and efficiency
✔️ Boiler protection – prevents cold return water from entering the boiler, extending its service life
✔️ Thermal insulation – PRO versions are factory insulated (EPP), reducing heat losses and improving efficiency

✨ Why use Elterm PRO low loss headers?

• They improve the reliability and stability of the entire heating system

• They simplify design and future expansion of multi-circuit installations

• They help extend the service life of boilers and pumps by optimising hydraulic conditions
