Veissman Low Loss Header - 80/60

PN: 7498 529

Includes Low Loss Header Insulation

Connections: NPT 1 1/4"

Made In Germany

When used in conjunction with the Viessmann boilers, the low-loss header acts as a hydraulic break, decoupling boiler and system circuits from each other. It is recommended to use the low-loss header in applications in which the total system flow rate exceeds the maximum boiler flow rate. The temperature sensor well located at the top of the low-loss header ensures low return temperatures to the boilers, at all times, increasing operational efficiency. In addition, the low-loss header helps eliminate air and debris from the heating system.

LOW-LOSS HEADERS

The benefits at a glance:

• To decouple high flow rate systems from the boiler loop.
• Enables constant flow through boiler.
• Avoids flow problems in secondary heating circuits.
• Promotes boiler condensation when used with condensing boilers.
• Protect boiler heat exchanger.
• Helps eliminate air, sediment, and debris from the heating system.
• Stand-by losses minimized by highly effective foamed in place or mineral wool insulation (optional accessory).
• Used as a separation point between boiler and system loop for troubleshooting purposes.

When to use a low-loss header:

• When the system flow rate exceeds the maximum boiler flow rate.
• When the boiler flow rate exceeds the maximum system flow rate (usually in multiple boiler systems with a low system delta t).
