Transformation of conventional heating networks towards low-temperature networks through secondary-side measures
Alternative energy sources for district heating such as waste heat, solar and geothermal energy and heat pumps only develop their full potential at low temperatures. The transformation of conventional heating networks to low network temperatures is the goal of the T2LowEx project. The AIT developed innovative business models for the implementation of measures to reduce return temperatures, evaluated them based on concrete case studies and discussed them with heating supply companies. Since these measures are often subject to customer responsibility, tariffs for customer motivation are promising: The customer implements the measures to actively reduce return temperatures, and he receives "payback" in the form of a discount on his district heating bill depending on the return temperature and the savings thus achieved - a win-win situation for the network operator and the customers.
