The Whitehall District Heating Scheme (WDHS) was first designed way back in the 1930s to replace the inefficient open coal-fire heating of offices that were used at the seat of the UK Government in London. The installation of boilers began in the 1950s, and the full scheme began operating by 1966. Since then, the central boiler plant has had several upgrades in order to improve its performance and economy. The scheme supplies 23 government buildings through 24 km of distribution pipework that are routed through a complex network of underground tunnels. The buildings that are covered by the scheme includes downing street, the Ministry of Defence, the Foreign and Commonwealth office, the Department for Environment, Food and Rural Affairs, Horse Guards, the Treasury. The Whitehall District Heating Scheme (WDHS) supplies 33.9 GWh per year. Heat losses from the extensive distribution pipework network come to approximately 2 GWh per year, about 6 per cent of the total heat generated. This figure for heating losses is similar to schemes of the same vintage.
