Project
Following a series of leaks, we have been asked to provide a cost for replacing the LTHW pipework that serves the CSSD plantroom and a DHWS Calorifier.
The existing heavy steel pipework had reached the end of its operational life, necessitating a transition to stainless steel pipework. This replacement had to be executed while ensuring continuous heating to the air handling units and domestic hot water, with the operation constrained to a single 24-hour downtime window.
The Solution
We replaced the external Low-Temperature Hot Water (LTHW) heating pipework that extended from the plant room, traversing the roof and passing over the CSSD AHUs and DHW heater.
All new pipework was installed using stainless steel crimped fittings.
A new big foot bracket system was implemented.
The pipework was insulated with Rockwool insulation and clad in aluminium.
downtime, the pipework was switched over during off-hours. The system was then rebalanced, dosed, and re-energised.
The Benefits
The old pipework was failing and leaking regularly, causing downtime and call-outs for the leaks to be repaired and putting the system at risk due to the loss of water treatment protection chemicals. The new stainless steel pipework offers an installation that should last for many years, reducing (if not eliminating) loss of services due to leaks
