暖色旳夢變栤涼旳枷鎖 07-10 10:11

冬季，当室外温度接近或低于0oC以下以及遇到大风天气，每次使用完热水器必须进行排水处理，放尽热水器内的积水，以防冻坏水箱，损坏热水器，排水方法如下：
1、常用防冻：当气温低于0℃，每天最好少量、多次使用热水器里的水。尤其在睡前和起床后，放少量水使管道内的水流动，依靠水温来增加管道温度。气温越低越要多放水，以防水管冻堵。
2、滴水防冻：平时留心天气预报，当气温降到-7℃以下时，晚上用完热水后，将水箱上满水。然后在喷头或水龙头下接一水盆，把热水阀松开一点，使其慢慢滴水，以保持管道内水的流动，一般一晚上一盆水的流量可避免管道冻堵。
3、排空防冻：如果管道在安装时没有反坡的话，用完水后，可将热水器放空，并保持放水阀常开，这样就不会使管道冻堵。
希望可以帮到您，祝您生活愉快~

1，燃气热水器一般安装在厨房，在室内应该不会冻住吧。要放水，在机子下面有一个长螺栓，松开就可排水，排完用手拧紧。
2，平时在家的时候，也就是家里用热水高峰期，保持热水器电源开启状态，气阀开启状态，热水器只要不通水，它是不会启动的，用的时候，只需要开启热水龙头就行了，热水器会自动启动。家里没人，建议关掉热水器电源即可，没有电，热水器里面的电磁阀是不会开启的，就没有泄露危险。家里长时间没人，比如外出旅游，度长假，关闭气阀，关闭电源，插头不用拔掉(这是为了北方机型，有些是防冻的，气温过低会自动启动加热装置，如果拔掉插头，加热不会自动启动，也就没有保护措施了，家里温度过低会冻裂热水器水管)，也可以放掉热水器里面的剩水，具体操作参照说明书，肯定有此项，这样的话，插头也可以拔掉

是的
燃气热水器防冻装置的工作原理：
防冻是通过电加热元件来实现的。在热水器水管上安装电加热装置，一旦检测到水管温度过低时，即接通电源进行加热。热水器的电源插头必须始终接通电源自动防冻装置才能起作用。
