Here in the UK, heating tends to be supplied on-site in individual buildings. The most common sources of heat are gas boilers, electric heaters and oil powered boilers.
However, in many parts of the world, it is common to have networks to transport heat to consumers through insulated pipes. This process is called “District Heating”.
In these cases, the heat source is not contained inside the individual building. It is generated locally and is distributed to many consumers via a network of pipes. It’s not dissimilar to a domestic central heating system, but on a much larger community scale.
As it is built on a far larger scale than a typical domestic central heating system, District Heating Schemes allow those participating in them to benefit from low carbon technologies and the economies of scale. A more efficient generation of heat and fewer carbon dioxide emissions also helps the environment.
In addition, as there is no gas supply or gas boiler in your home and therefore your home is inherently safer, and annual safety checks associated with a gas boiler due to the risk of carbon monoxide are not required.
