Hello Rupert
I have very briefly answered some of your questions
It should be ensured that hot water is stored within the HWS cylinder at equal to or greater than 60C and hot water services temperature at the outlets should achieve a temperature of at least 50C within one minute of flushing.
Temperatures exceeding 60C at the outlets pose a significant scalding risk. I suggest that the outlets are identified and clearly labelled ?Very Hot Water? using the appropriate signage in accordance with The Health and Safety (Safety Signs and Signals) Regulations; 1996.
You state that your hot water is currently too hot to use. I would therefore consider fitting mixer taps or thermostatic mixing valves as suggested by our Peter Kay & Pheonix Nights fan, Brian
It should be ensured that hot water supply to thermostatic mixing valves/taps is equal to or greater than 50C. Additionally, temperatures ranging between 38 ? 42C should be obtained to prevent scalding of users.
WRc/WRAS Approved Type 3 fail safe thermostatic mixing valves and taps are utilized to prevent scalding of users. (NHS Estates Specification D08 - refer to section 3.6)
I would suggest, that a full and detailed Legionella Risk assessment is carried out on your water plant and distribution systems. The RA will identifiy the sentinel outlets for monthly temperature profiles, asset all water related plant and a 2 dimensional schematic should be produced
