Can hot and cold water temperature and outlet flushing move from a fixed interval to a condition-based check?

Partly: part of the task converts to a condition and part stays on the calendar. Monthly temperature checks and weekly flushing follow HSG274 and AS/NZS 3666; the risk assessment sets the interval, and continuous sensing with alarms is an accepted way to meet it, but the annual risk assessment review stays.

What condition would trigger hot and cold water temperature and outlet flushing instead of the calendar?

Yes. Temperature sensors at sentinel outlets and calorifier flow and return log continuously and alarm when hot drops below 50 C or cold rises above 20 C; flushing of little-used outlets can be automated with timed flush valves.

What reading proves hot and cold water temperature and outlet flushing was done?

Hot water at the outlet above 50 C within one minute, cold below 20 C within two minutes, calorifier flow above 60 C and return above 50 C. Observed by: Wireless temperature sensors at sentinel points; automatic flush valves with a run log.

What evidence does hot and cold water temperature and outlet flushing produce for an ISO 55001 or ISO 45001 audit?

Temperature log per sentinel outlet (sensor export or monthly readings) and the flush log for little-used outlets

Hot and cold water temperature and outlet flushing

A monthly temperature reading is a single point on a curve that a sensor draws continuously. The regulator wants the curve; give it the sensor export.

Condition that replaces the interval: Yes. Temperature sensors at sentinel outlets and calorifier flow and return log continuously and alarm when hot drops below 50 C or cold rises above 20 C; flushing of little-used outlets can be automated with timed flush valves.
Reading that proves it: Hot water at the outlet above 50 C within one minute, cold below 20 C within two minutes, calorifier flow above 60 C and return above 50 C
Why the interval stays: Monthly temperature checks and weekly flushing follow HSG274 and AS/NZS 3666; the risk assessment sets the interval, and continuous sensing with alarms is an accepted way to meet it, but the annual risk assessment review stays.
Evidence an auditor accepts: Temperature log per sentinel outlet (sensor export or monthly readings) and the flush log for little-used outlets
First move: Name the sentinel outlets in the register and attach the sensor to those, not to a random tap on each floor.
