Heating technologies in District Heating

District heating networks can be fed by various heat generation sources, including combustion plants (based on fossil fuel or biomass), CHP (combined heat & power) plants or renewable-based plants. The characteristics of each of these heat technologies are outlined in this article. This review is included in the document "D4. 1 - Energy Price Assesment", that provides an insight to energy cost in the context of district heating. Download this article here >> The combination of multiple heat sources is beneficial, especially for large district heating schemes, as it allows shifting from source to source depending on specific conditions and market prices. In Figure 1 is shown the heat production mix for European countries. Figure 1 Heat sources for district [...]

Energy Price Assessment: an insight to energy costs in the context of District Heating

The energy price assessment performed in the document “D4.1 – Energy Price Assessment" provides a comprehensive review of the main heat production systems and primary energy sources associated with District Heating systems in Europe. Geothermal heat flow density in Europe. EC 2012. © EC, 2012. District heating (DH) systems are one of the most energy efficient heating systems in urban environments and they are also key systems in the de-carbonization of heating energy in European Cities. Renewable and waste heat sources are foreseen at the same time as de-carbonized heat sources and the way to guarantee competitive energy costs with limited influence of fossil fuel supply price volatility. To achieve this, conversion of DHs is needed. RELaTED will [...]

Unglazed Solar Thermal Systems for Building Integration, coupled with District Heating Systems

The connection of a solar thermal (ST) façade system to a district heating system allow for the direct use of ST heat in the building, while taking profit from the network for delivery/selling of excess heat and purchase of heat during periods of underproduction. The use of unglazed collectors for low-intrusive architectural interaction in façades is discussed. Studies are carried out on the heat production of the system and its capacity to cope with local demands. Economic studies are carried out in order to balance the investment and operational costs/profits of the system. In this paper, presented in the ICAE conference in Donostia-San Sebastian, the energy performance of a solar thermal (ST) façade system is studied in relation to its [...]

Know more about Low Temperature District Heating solutions

RELaTED project trifold. District heating is one of the most energy efficient systems to deliver heat in urban environments. Despite this fact, energy market requires a conversion of actual DH concept. This is the main objective of RELaTED concept, that will provide an innovative system of decentralized Ultra-Low Temperature (ULT) network solution that can pave the way for expanding and modernizing existing district heating networks. Find more information about RELaTED low temperature DH solutions in project dissemination materials. […]
