Is a low loss header required for every application?
No, but recommended for most applications with multi-zones. A low loss header—also referred to as a hydraulic separator —is available for every Rinnai Boiler. The low loss header isolates the boiler from the rest of the system to protect the components within the boiler (heat exchanger, pump, etc.) and to optimize overall performance, efficiency and longevity for the Rinnai Boiler.
