Vaillant Wh95 Low Loss Header

Vaillant WH95 Low Loss Header Overview

The Vaillant WH95 Low Loss Header is designed to maintain the correct flow of water through the boiler while ensuring a consistent temperature supply to multiple heating circuits. It plays an important role in larger heating systems where more than one heating circuit is in use, helping to balance the system and improve overall performance. By separating the boiler circuit from the heating circuits, the low loss header helps prevent flow rate issues and allows the boiler and heating circuits to operate efficiently without affecting each other.

System Performance and Efficiency

The main function of the Vaillant WH95 Low Loss Header is to ensure the correct flow rate is maintained through the boiler while providing a steady flow of heated water to downstream heating circuits. This helps improve system efficiency, reduce strain on the boiler, and ensure consistent heating performance across multiple zones or circuits. Low loss headers are commonly used in larger properties or commercial installations where multiple heating zones, underfloor heating systems, or radiator circuits are connected to one boiler.

Installation and Specifications

The Vaillant WH95 Low Loss Header is designed for use in larger heating systems and includes 2" BSP female connections for easy integration into the system. It is built to handle high flow rates and maintain stable system pressure and temperature.

FAQs

What does a low loss header do?

A low loss header separates the boiler circuit from the heating circuits, ensuring the correct flow rate through the boiler while supplying a steady flow of heated water to multiple heating zones.

When do I need a low loss header?

A low loss header is typically required in larger heating systems with multiple heating zones, underfloor heating, or commercial systems where different circuits need to operate independently.

Is the Vaillant WH95 suitable for high flow systems?

Yes, the WH95 is designed to handle high flow rates up to 8 m³ per hour, making it suitable for larger domestic or commercial heating systems.
