Boiler Room Upgrade at Kensington Palace

The works are located within the Boiler Room serving the offices in apartments at Kensington Palace. The project comprises the replacement of the existing end-of-life atmospheric gas boilers with new high-efficiency condensing boilers, together with the installation of new hot water cylinders, associated pipework, valves and plate heat exchangers. The new heating system shall be designed to facilitate future connection to a heat network, which is currently being investigated through a joint RHPS/HRP feasibility study. The existing boiler flues, originally designed for atmospheric boilers, shall be surveyed and either replaced or relined as required to suit the new plant. The Contractor shall also assess the adequacy of the existing gas supply and undertake any necessary upgrades, including the replacement of obsolete mechanical gas drop safety valves with modern electrically operated solenoid valves. The works shall include, but not be limited to:

• Removal and disposal of existing boilers, associated plant and redundant equipment.
• Installation, testing and commissioning of new condensing boilers.
• Installation of new hot water cylinders, plate heat exchangers, pipework, valves and associated ancillaries.
• Survey, replacement and/or relining of existing flues as required.
• Upgrades to the gas supply infrastructure where necessary.
• Removal and replacement of all electrical installations and equipment required to serve the new plant.
• Cleaning, flushing and dosing of the existing heating system to protect both the new plant and retained system components.
• Replacement of all thermostatic radiator valves (TRVs) and lockshield valves.
• Associated builders' work, making good and redecoration of the plant room upon completion of the works.
• Testing, commissioning and provision of all relevant certification, operation and maintenance manuals, and handover documentation.

The completed installation shall provide a significantly improved level of energy efficiency compared with the existing system while maintaining reliable heating and hot water services and enabling future integration with a district heat network.
