Hot & Cold Water Temperature Monitoring

Temperature requirements of hot and cold water: Flow temperature at calorifier – minimum of 60˚C eg; cylinder/ calorifier stored water Return temperature to calorifier – minimum 50˚C Hot water at outlets – minimum of 50˚C – within 1 minute of running outlet. If over 60˚C then action should be taken to reduce temp or advise remedial action to prevent scalding risk Mixed water (TMV) – between 38˚C - 46˚C from water outlet Inlet to TMV – minimum of 50˚C on pipe surface Stored cold water - 20˚C or less eg; cold water storage tank. Cold water at outlets - 20˚C or less within 2 minutes of running the outlet. All sentinel outlets can be identified within the Legionella Risk Assessment or by contacting the Water Hygiene Team. Ensure all failed items be raised via the Compliance Team following completion of this PPM. I can confirm all required temperatures have been measured during this task following the above guidance with a calibrated, submersible and surface temperature probe.
