When Is Hot Water Temperature Maintenance Trace Heating Required?

Hot water temperature maintenance trace heating ensures hot water at the point of use, whilst reducing power consumption and water wastage, as well as offering the option to disinfect periodically against Legionella.

The temperature of hot water cools rapidly when subjected to lower ambient temperatures and under no-flow conditions. By installing hot water temperature maintenance trace heating, under thermal insulation, the hot water in the pipework can be maintained above its minimum required temperature (usually +55°C or +65°C) in a predetermined minimum ambient temperature (usually +18°C).
