在自然循环情况下,系统的循环压力来自水的比重差,所产生的循环压力通常只有大气压的千分之几,因此,往往在系统中出现一个气泡就会严重阻碍循环的实现。使用了家用暖气循环泵后，使暖气的安装大大简单化。在自然循环情况下，为了保证系统的循环压力，暖气片和炉具必须在重力方向离开必要的距离，由此产生了“散热器高挂”或“炉具入地”等问题。采用强迫循环，不用考虑散热器及炉具的相对位置，甚至炉具高于散热器，也不会影响系统的循环。由于自然循环的动力很小，因此通常采用很粗的干管以减小系统阻力，即便如此，系统也经常出现循环或散热问题。使用了家用暖气循环泵后，可以适当减小干管的直径，从而简化安装、优化循环、美化外观。自然循环的最大的缺点是散热器利用效率低。一般情况下散热器的上下温度差高达40度以上。采用强迫循环，可以减少散热器的上下温差。按相同的散热量计算，估计可以节省散热片20―30%。加上由于减小干管的因素，每个系统可以节省一笔可观的费用。

按在暖气的回水管上.循环泵装在回水管上的好处是：1.回水管的水温低，对水泵寿命有好处；2.必须在回水管路上(水泵之前)安装一个过滤器，并定期打开疏通。
