The Client required the existing boilers to be replaced as two had been condemned and spare components were no longer available, thus rendering them obsolete.
The plate heat exchangers and buffer vessels providing the hot water were also struggling to meet the additional demand. The hot water requirements for the wing have increased therefore rendering the existing system lacking in capacity at peak usage times.
Due to the need for an uninterrupted supply of hot water to serve the wings during the works, it was necessary for the decommissioning of existing and installation/ recommissioning of new boiler plant to be phased in order to maintain hot water / heating provision. Any planned downtime during switch overs, gas supply upgrades etc. to be managed for times of low demand and to allow for sufficient time for water in systems to heat up.
