- 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.
- 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.
- Used as a separation point between boiler and system loop for troubleshooting purposes.
