水经暖气片放热后，温度降低，所以水管CDA段中的水温较低，密度ρA左较大，
根据液体压强公式p=ρgh，A截面左侧CDA段中的水产生的压强大于右侧ABC段水的压强，因此水管中的水会按逆时针方向流动．
同时安装水管时又有一定的坡度，即D端高、A端低，为水的逆时针流动创造了有利的条件．
（2）当水管中有空气时，气泡会沿管道向上移动，并汇集在最高处，包括管道中向上凸起的部分、暖气片的顶部等处．
如果汇集的气体过多，会形成气柱，分断了水管中的水，阻碍水的流动，从而影响用热水供暖的效果．
（3）水箱中的水位一定要高于整个循环水路的最高点，才能在整个循环水路中灌满水，
否则循环水路中就会有空气，水就不能正常流动，从而影响用热水供暖的效果．
