District Heating System’s links the heating systems of a number of dwellings, buildings or units on a site or development. These links allow the system to transfer heating from one site to another increasing efficiency. This is achieved by using larger more efficient equipment located in the basement, by matching thermal demand on different sites to maximise efficient plant operation, and by using Renewable, Sustainable or Alternative Heating. It also creates cost efficiencies through improved management, reduced maintenance and the bulk purchase of fuel.
So does it work. Well like all large systems it comes down to the management. A well managed district heating system is far more efficient than individual well maintained boilers. In some cases I’ve come across systems that are horribly badly designed and managed. These ones suck and give the rest a bad name.
