Will the heating and drainage upstairs affect the heating downstairs?

The heating and drainage upstairs will not only affect the heating downstairs, but also affect the heating of the whole building and even the heating of the whole community.

1, the reason why the heating and drainage upstairs affect the heating downstairs and the whole building;

If a building has a large amount of drainage, according to the law of node pressure balance, the water supply pressure of the branch nodes downstairs will be reduced, which will seriously lead to the pressure at the entrance of the building. Under the condition that the return water main pressure is constant, the inlet pressure will decrease, the pressure difference between supply and return water will decrease, the circulating flow will decrease, and the heating quality will be affected.

2. The heating water is discharged upstairs, which affects the heating of the whole community;

Drainage upstairs will reduce the circulating water in the system. At this time, in order to ensure the normal operation of the heating system, it is necessary to replenish water to the system. The supplemented water is softened water with a temperature lower than that of the heating return water, which is equivalent to reducing the total temperature of the return water. If the temperature of circulating water passing through the boiler is fixed, it is equivalent to reducing the total temperature of water supply, so it has an impact on the heating of the whole community.
