Zusammenfassung:This paper introduces the current state of solar heating system among Wanzleben city heating net. In view of low efficiency (only 20-30%) of this system, it analyses the shortcomings of this applied system from sensors' situation, fixed flow problem, the influence of the user's water temperature and the length of pipe separately. Some improving methods which are effective by theoretical analysis are suggested. The implementation steps have to be discussed in more detail with the utility.
