How do you diagnose it?
Log tank temperature at multiple heights; Verify recirculation flow and direction; Mixing valve test at varying demand; Draw-off profile measurement. The readings are recorded so the repair decision is based on data.
Can I keep using the system in the meantime?
No — isolate the plant and call 069 268 0988. Running it in this condition risks further damage or an unsafe situation.
