To comply with legionella prevention guidance; water must be stored at no less than 60 degrees and distributed at no less than 50 degrees, however where the risk of scalding has been identified thermostatic mixer valves (TMV's) are fitted to regulate the temperature at the outlets.
It is a requirement that all TMV's are checked once a year to ensure they are still achieving the desired temperature. If temperature control fluctuates more than 2 degrees from the original setting then a full service will be required. The valves can easily become scaled or blocked which needs to be rectified to ensure they work properly.
