小户型（如廉租房）用地板采暖比较好，可增大可使用面积。但家具尽量不要采购落地的，比如床（柜子一般落地，没办法），如果落地，会减少3平米散热面积，盘管得先加热床体，才能加热房间，效果不好，设计师最好提醒甲方。

双管上供上回最不好，最多两层，三层或更多的话，高差太大，重力水头太大，容易失调。lwxjigevlkyarsbsxo
平房一般做上供上回。

双管系统忌讳出现四通，容易上边热，下边的不热，可以考虑把错开一定距离，四通改为两个三通，如下（详见李娥飞通病分析）

2.卫生间淋浴器墙体防水要做高于1.8m，没有淋浴头的地方，防水距地400mm，所以卫生间出的采暖管道应从门进出（没有防水），否则就得买防水套管，不应穿卫生间的墙，这样会破防水，时间长了会阴湿到下一层。tclzbqgvfbklucrjlknatihbv

华北标（91SB1-1第 67 页做法）是错的，5（手动调节阀或平衡阀）装得太多了，实际工程中出现问题了。应采用国标图集04K502第16页。vlspoqojhpkfzza
