Local Heating Networks with Waste Heat Utilization: Low or Medium Temperature Supply?
Energies, 2020 District heating enables an economical use of energy sources that would otherwise be wasted to cover the heating demands of buildings in urban areas. For efficient utilization of local waste heat and renewable heat sources, low distribution temperatures ...

Integration of space heating and hot water supply in low temperature district heating [PDF]
Energy and Buildings, 2016 Abstract District heating may supply many consumers efficiently, but the heat loss from the pipes to the ground is a challenge. The heat loss may be lowered by decreasing the network temperatures for which reason low temperature networks are proposed for future district heating. The heating demand of the consumers involves both domestic hot water and

Minimizing the supply temperature at the district heating plant – dynamic optimization [PDF]
E3S Web of Conferences, 2019 The constraint contains two elements, namely the heat losses and the electricity consumption for pumping at the producer. The aim was to achieve the lowest acceptable costs in an operation. The options with the supply temperature at the area starting point set to 80/60, then 60/40, and eventually 50/30 (low temperature, 4th generation district heating)

Performance Analysis of a District Heating System
Energies, 2013 Lowering the exergy content of heat required for heating purposes decreases the primary energy consumption. District heating systems are often an important link between facilities that generate heat with low exergy content and consumers.
