Project overview

Imperial College London required the replacement of an existing three-phase electric heating element connected to its Building Management System (BMS). The work was carried out on behalf of principal contractor Dalkia.

The hot water storage tank was drained before the existing element assembly was removed. A new three-phase element was installed, with the connections prepared and sealed before the electrical wiring was completed.

The replacement was connected to the existing supply and BMS. Additional control wiring provided a cut-out signal at the specified water temperature of 60°C, allowing the BMS to respond to that limit.

The completed installation

The heating element replacement and associated wiring were completed within one day. The work restored the system’s heating functionality and connected the replacement element to the existing BMS control arrangements.

The installation brought together the heating equipment, three-phase supply and temperature-control wiring, including the dedicated 60°C signal connection.
