District energy systems are used widely across Europe, providing cities and towns with affordable, low-carbon heating and cooling.

District heating networks supply heat and are fuel and technology agnostic, i.e., any source that can heat water can be used to supply the network. This means district heating supports all potential suppliers of heat, from geothermal, biomass and industrial waste heat to solar thermal and CHP.

As a result, district energy indirectly supports these other industries, and IrDEA in turn benefits from this shared interest with other associations representing these industries in Ireland.
