London Fire Station, Heating Upgrade


The heating and hot water plant was at the end of its economic working life and was in need of major upgrade to new, modern and efficient equipment.
The works included the provision of two modular condensing boilers and a new Combined Heat and Power Unit serving a low loss header together with a new Hot Water Storage calorifier to provide hot water to all sanitaryware throughout the Station.

Secondary circuits were taken off the low loss header to serve five separate variable temperature heating zones and an HWS primary circuit to the new hot water storage calorifier.

All circulating pumps were electronically speed controlled and the entire pipework system was insulated, and colour coded.

A completely new Trend based control system was installed with a new control panel/outstation and an all new carcass and wiring system installed within the boiler room and Appliance Bay.

All heating pipework and heat emitters were installed throughout the Station complete with new thermostatic radiator vales, regulating and isolating valves.

The heating system was thoroughly flushed out and the completed system dosed with a suitable corrosion inhibitor and biocide and the hot water system was chlorinated.

The complete installation was commissioned, regulated and handed over in full operating order. The new systems were run under automatic control for a period to time before handover to prove the system were fully operational
