What is Community Heating?

Community Heating, also referred to as District Heating, is a system for distributing heat generated in a centralised location through a network of insulated pipes to multiple buildings or residences. This approach is particularly efficient for densely populated areas, as it reduces the need for individual heating systems in each property.

Community Heating systems are typically powered by a variety of energy sources, including combined heat and power (CHP) plants, waste-to-energy facilities, geothermal energy, or large-scale heat pumps. The heat is transported via hot water or steam through an underground network of pipes, delivering it to homes, offices, and other buildings. This method is highly energy-efficient, as it minimises heat loss and maximises the use of renewable or low-carbon energy sources.

In the UK, Community Heating aligns with the government’s Net Zero Strategy and Building Regulations, particularly Approved Document L (Conservation of Fuel and Power), which emphasises energy efficiency and carbon reduction in building design and operation.

Practical Example:
A notable example in the UK is the Pimlico District Heating Undertaking, which has been supplying heat to over 3,000 homes and businesses in London since the 1950s. This system uses waste heat from Battersea Power Station, demonstrating the potential for integrating Community Heating with existing infrastructure.
