The most direct impact of discharging hot water for heating is that the heating cycle pressure of the whole building or the whole area is unbalanced, and hot water cannot be replenished to the homes of high-rise residents, thus affecting the heating effect of more residents' homes. When a large number of users discharge hot water, the corresponding heating pressure will be reduced and a lot of heat will be lost. Adding a lot of cold water will reduce the heating temperature and affect the heating quality.
