Advantages Of A District Heating Network
District heating networks provide the means to transport heat efficiently. They can currently be built up to around 30km from generating plant and distribution networks can be hundreds of kilometres long. This is sufficient to carry heat across our cities, smaller communities and industrial areas. The distance a network can reach is also easily extended by simply adding more providers of heat, or heat sources, along the way.
A heat network enables valuable energy, which currently is all too often wasted in power generation or industrial processes, to be harnessed and delivered to a point of use. This removes the need for additional energy to be generated. It also allows for economies of scale, as the generation of heat in one large plant can often be more efficient than production in multiple smaller ones.
Heat networks can also be supplied with heat from a diverse range of sources like:
Networks also have the ability to balance the supply and generation of heat, across location and over time. Over the course of the day, heat demand shifts between residential consumers to commercial, industrial and public buildings and back again. A heat network can match and manage these flows, whilst maximising the utilisation of the plant providing the heat. Demand can also be managed across seasons, with networks supporting the operation of distributed absorption cooling plants in the summer providing cooling on a significant scale.
