running alongside hot pipes must be heavily insulated to prevent the hot pipes from warming the cold water into the Legionella growth zone (above 20°C). Materials and Corrosion Control
BS 8558 aligns with HSE guidance (HSG274) regarding storage: : Test the system at 1
Sizing pipework, material selection, and choosing appropriate storage solutions.
By strictly adhering to BS 8558 for hot water services, you ensure: : Take water samples for microbial analysis if
Inspect the internal cleanliness of hot water storage vessels and drain accumulated debris/sludge, which can harbor bacteria. Summary of BS 8558 Hot Water Benchmarks Target Requirement Storage Temp Minimum 60°C Eradicates Legionella at the source Return Loop Temp Minimum 50°C (55°C in healthcare) Prevents temperature drop in distribution Outlet Temp Minimum 50°C within 60 seconds Ensures hot water reaches user safely Safe Tap Temp 38°C - 43°C via TMV Prevents scalding while maintaining system heat
Hot water in calorifiers or cylinders should be stored at 60°C or higher.
Hot water systems (showers, taps, storage vessels) are high-risk areas for bacterial growth, specifically Legionella bacteria, which thrive between 20°C and 45°C. is crucial because it helps minimize these risks through proper design and maintenance. 1. Design and Installation
