The requirement
The hospital’s boiler-room piping was largely insulated, while many fittings were exposed. The project specified reusable covers with a target outside-surface temperature.
How the design was approached
The team surveyed exposed components and agreed materials, closures and identification tags. Hospital maintenance staff installed blankets on the steam header, instantaneous heater and condensate pumps.
Construction and fit
The hospital specified 38 mm of needled glass-fibre mat, PTFE-impregnated glass cloth, opening straps and a drainage eyelet for wet locations. Its specified outside-surface objective was below 49 °C.
Reported outcome
The project report describes a weather-normalised comparison of steam production before and after installation. The reported annual cost avoidance was nearly three times the audit projection.
