Renewable and Waste Heat Recovery for Competitive District Heating and Cooling Networks

REWARDHeat aims to demonstrate a new generation of low-temperature district heating and cooling networks, which will be able to recover low-grade renewable and waste heat, available at low temperature.

Watch the video below to learn more about the innovative research into low-temperature networks being carried out by the REWARDHeat project!


72% of the European population (EU28) live in urban areas, characterised by large demand for heating and cooling services. A large amount of low-grade waste heat is available in these areas, emitted by air conditioners, refrigeration, data centres and industrial processes. The new generation of DHC networks will increase production and distribution efficiency by recovering this locally-available, renewable heat.

The focus is on the exploitation of the energy sources available within the urban context, allowing to maximize the replicability and upscaling potential of the decentralized solutions developed in the project. The REWARDHeat solutions promote a cost efficient and technically viable decarbonization of the European DHC sector.

REWARDHeat will promote punctual metering, thermal storage management, network smart control as means to enable and optimise the exploitation of renewable and waste heat in DHC networks. At the same time, this approach permits a change of paradigm with respect to the business models devised: thermal energy will be sold as a service to the customers, rather than being viewed as a commodity.

Solutions will be developed at 8 demonstration sites across 7 European countries. Additionally, 3 early adopters not implementing actual demonstration measures, but fully involved in the project consortium, will develop preliminary projects for the upgrade of their networks integrating waste heat from different sources.
