New Guideline for Low Temperature District Heating

摘要

Low temperature district heating systems comply with two main requirements for the future district heating and the whole energy sector: high energy efficiency and high share of renewable energy. A number of demonstration projects have proven that a district heating supply temperature at slightly above 50℃ can meet the end-user's space heating and domestic hot water demands in central-northern European climates, in properly designed and operated district heating networks and in-house installations. Based on the experiences from the demonstration projects a guideline for low temperature district heating has been elaborated.
