Low Loss Header Installation explained
A correctly sized header decouples the circuits and, with proper sensor positions, finally lets the controls see true system temperatures.
- Header sizing and velocity: Confirm the component identity and model-specific requirements before deciding whether adjustment, testing or replacement is appropriate.
- Sensor pocket positions: Compare the input reading, requested output and actual equipment response; an error code is a starting point, not a diagnosis.
- Air and dirt separation: Confirm the component identity and model-specific requirements before deciding whether adjustment, testing or replacement is appropriate.
- Primary pump matching: Distinguish a pump fault from air, restrictions or closed valves elsewhere in the circuit.
Interpreting the reported fault
Define the required duty, operating hours, available space and connection routes before comparing models. Agree what commissioning and handover will cover. A product price alone is not an installed-system quote.
- Reported symptom: primary and secondary circuits fighting each other
- Record when the problem started and any recent changes
- Keep fault codes and model details for the assessment
Before specifying new equipment

What the reported symptom tells us
primary and secondary circuits fighting each other. Record when this occurs, what changed beforehand and whether other equipment is affected. These observations narrow the investigation; they do not prove which part has failed.
