上海某小区居民反应冬天热水器放不出水是水管冻住了还是什么情况？怎么解决？
1、当水流过大，热水与进水温差超过25度时，每分钟热水流出量达不到额定热水升。
2、没有足够的汽油，没有汽油，没有水，天气不会热。
3、点火装置故障，如果电池点火，看电池是否没电。
4、热水器换热器积炭过多，机器燃烧时容易出现积炭现象，大大降低了热水器的热水功率。
5、如果热水管道太长，冬天会很快散热。没有办法保证热水到达出口时的温度是温暖的。
燃气热水器使用注意事项：
1、定期清洁。由于水中杂质较多，用于消毒的余氯、管道中的沉淀物、铁锈等都会带入热水器，使水质恶化；如果长期不清洗，加热棒上附着的水垢会影响加热效率，增加能耗。此外，水中沉积的杂质和金属屑也会引起皮肤病，对敏感皮肤、老人和儿童会引起皮肤瘙痒、过敏等不适。因此，清洁是热水器使用中不可忽视的问题。
2、热水器应该每两三年清洗一次。操作时注意拔出塞子，关闭电热水器下冷水和热水的角阀，待水冷却后清洗水缸。为保证安全，防止清洗不干净、缺少专业设备和损坏热水器，建议在条件允许的情况下请专业维修人员进行清洗。
现在很多居民使用的PPR水管是塑料件，传热能力差，有一定的防冻能力。但如果温度太低，则会结冰（2.5mm管壁能抵抗-5℃左右的低温，3.2mm管壁能抵抗-10℃左右的低温）
1、如果水管结冰，太阳出来后，可以晒一会儿太阳，看看能不能打开水管。前提是白天最高气温在0度以上。如果最高气温仍然低于零度，解冻的希望就不大了。
2、如果太阳不融化，那就是热水。但一开始不要直接用热水，否则水管容易损坏。应用温水倒几次，然后取一壶热水，均匀地倒在管子上来回，注意不要烫伤自己。如果冻得很厉害，可以浇几次直到水管打开。
3、你也可以用电吹风吹冷冻水管取暖。吹的时候，你需要把它转到一个大的位置。你得先从水龙头开始。有时水龙头结冰了。如果水龙头打开，滴水，你就不需要再吹水管了。如果水不流动，沿着水龙头慢慢加热水管直到它打开。
4、对于较厚的管道，可采用内加热法，即在拆除管接头后，向管道内注入温盐水，管道会迅速解冻。但是，这种方法很麻烦，应该仔细考虑。
5、为了防止水管再次结冰，可以用破棉衣、塑料泡沫或塑料保温管来盛装水管。必须从水龙头底部绑到水管底部，然后用铁丝捆扎。这样可以防止管子结冰。
6、如果水管里的水是限时供应的，也就是说，过了一定时间就不会流了，等水用完了再关水龙头，这样水管里就不会有太多的水了，这样水管就不会结冰。怕浪费水，可以把水接到水桶或其他地方备用。
7、如果室内水管结冰，不要用热水烫伤。你可以把热炉子放在水管旁边，如果有暖气，也可以打开暖气。当室内温度升高时，冷冻水管会融化。
8、如果水管只是部分冻结，可以在水管上敷一个热水袋，让热水袋的持续热量融化冻结的水管。热水袋冷时，应及时更换热水。
9、若预算足够，可以在热水器上面安装WATERSUNNY循环泵，加速水管内的水循环，更好地防止管路内的水冻住。
1、一旦水管结冰，居民喜欢往上倒热水，这更容易造成水管爆裂。如果冻蜀黍的水管长度只有50厘米左右，可以锯掉换新的水管。如果它有几十米长，用这种方法太浪费了。但我们也没有更好的办法，只能等它自然解冻。
2、首先烘烤或倾倒，然后寻找再生棉、石棉等作为保温层。如果地下结冰了，去自来水公司解决。他们有义务处理此事。
3、供水部门表示，市民还可以为供水设施提供简单的防冻保护。如果你能使用棉和亚麻织物和塑料泡沫，你可以包水管，水表和水龙头。晚上，应关闭厨房和卫生间的窗户，或轻轻打开水龙头，使水管里的水流动起来，而不是结冰。如果水管被冻住了，可以用电吹风吹干，也可以用毛巾包好，然后用温水慢慢倒。不要用火烤或开水烫，否则会使水管和水表爆裂。
水管冻结时，可根据管材采用以下解冻方法：
A 烘烤方法：如果水管是镀锌钢管，可以用电吹风烘烤水管。洪水烘烤要来回进行，不要在一个点上停留太久，否则水管会破裂。铝塑管、PVC管不能用这种方法。
B 热水溶解法：将冻结的管子倒入热水（温度要高一点），特别是在弯头处，直到溶解为止。此方法比较“温和”，对水管的损害几率较小，推荐此方法。
好了，以上就是冬天热水管路没水的可能原因以及水管冻住后的解决方法，更多水管和水泵的技术问题，欢迎与上海龙亚泵阀技术部探讨。
Shanghai residents of a community response in winter water heater water is frozen or what? How to solve it?
1. When the water flow is large and the temperature difference between the hot water and the inlet water is more than 25 degrees, the hot water outflow per minute can not reach the rated hot water rise.
2. There's not enough gas, there's no gas, there's no water, it won't be hot.
3. Ignition device failure, if the battery ignites, see if the battery is dead.
4. There is too much carbon deposit in the heat exchanger of the water heater, and the phenomenon of carbon deposit is easy to appear when the machine is burning, which greatly reduces the hot water power of the water heater.
5. If the hot water pipe is too long, it will dissipate heat quickly in winter. There is no way to ensure that the temperature of hot water at the outlet is warm.
Precautions for use of gas water heater:
1. Clean regularly. Because there are many impurities in the water, the residual chlorine used for disinfection, sediment and rust in the pipeline will be brought into the water heater, which will deteriorate the water quality; if it is not cleaned for a long time, the scale attached to the heating rod will affect the heating efficiency and increase energy consumption. In addition, impurities and metal filings deposited in the water can also cause skin diseases, which can cause skin itching, allergy and other discomfort to sensitive skin, the elderly and children. Therefore, cleaning is a problem that can not be ignored in the use of water heater.
2. The water heater should be cleaned every two or three years. When operating, pay attention to pull out the plug, close the angle valve of the cold water and hot water under the electric water heater, and clean the water tank after the water is cooled. In order to ensure the safety and prevent the water heater from being cleaned unclearly, lack of professional equipment and damage, it is recommended to ask professional maintenance personnel to clean if conditions permit.
Now many residents use PPR pipes are plastic parts, which have poor heat transfer ability and certain antifreeze ability. But if the temperature is too low, it will freeze (2.5mm tube wall can resist the low temperature of - 5 ℃, 3.2mm tube wall can resist the low temperature of - 10 ℃)
1. If the water pipe freezes, after the sun comes out, you can bask in the sun for a while to see if you can turn on the water pipe. The premise is that the maximum temperature during the day is above 0 ℃. If the maximum temperature is still below zero, there is little hope of thawing.
2. If the sun doesn't melt, it's hot water. But do not use hot water directly at the beginning, otherwise the water pipe is easy to damage. Use warm water to pour several times, then take a pot of hot water and pour it evenly on the pipe. Be careful not to scald yourself. If it's very cold, you can pour it several times until the water pipe is open.
3. You can also use an electric hair dryer to blow water pipes for heating. When blowing, you need to turn it to a big position. You have to start with the tap. Sometimes the tap freezes. If the tap is on and dripping, you don't need to blow the pipe. If the water doesn't flow, heat the pipe slowly along the faucet until it turns on.
4. For thick pipes, internal heating method can be used, that is, after removing the pipe joint, warm brine is injected into the pipe, and the pipe will thaw quickly. However, this method is troublesome and should be considered carefully.
5, in order to prevent water pipes from re freezing, they can be packed with broken cotton padded clothes, plastic foam or plastic insulation pipes. It must be tied from the bottom of the tap to the bottom of the water pipe and then tied with wire. This prevents the tube from freezing.
6. If the water in the pipe is supplied within a limited time, that is to say, it will not flow after a certain period of time. Turn off the tap when the water is used up, so that there will not be too much water in the pipe, so that the pipe will not freeze. For fear of wasting water, you can connect the water to the bucket or other places for standby.
7. If the indoor water pipe freezes, do not scald it with hot water. You can put the hot stove next to the water pipe. If there is heating, you can also turn it on. When the indoor temperature rises, the chilled water pipe will melt.
8. If the water pipe is only partially frozen, a hot water bag can be laid on the water pipe to allow the continuous heat of the hot water bag to melt the frozen water pipe. When the hot water bag is cold, the hot water should be replaced in time.
9. If the budget is enough, WATERSUNNY circulating pump can be installed on the water heater to accelerate the water circulation in the water pipe and better prevent the water in the pipe from freezing.
1. Once the water pipe freezes, residents like to pour hot water upward, which is more likely to cause the water pipe burst. If the water pipe length of frozen corn is only about 50 cm, it can be sawed off and replaced with a new one. If it's tens of meters long, it's too wasteful to use this method. But we also have no better way, can only wait for it to thaw naturally.
2. First bake or pour, and then look for recycled cotton, asbestos, etc. as insulation layer. If the ground freezes, go to the water company. They have an obligation to deal with it.
3. The water supply department said that the public can also provide simple anti freezing protection for water supply facilities. If you can use cotton and linen fabrics and plastic foam, you can wrap water pipes, water meters and faucets. At night, you should close the windows of the kitchen and toilet, or turn on the tap gently, so that the water in the pipe can move instead of freezing. If the water pipe is frozen, you can dry it with an electric hair dryer or wrap it with a towel, and then pour it slowly with warm water. Do not use fire or hot water, otherwise the water pipe and water meter will burst.
When the water pipe is frozen, the following thawing methods can be adopted according to the pipe material:
A baking method: if the water pipe is galvanized steel pipe, electric hair dryer can be used to bake the water pipe. Flood baking should be carried out back and forth. Do not stay at one point for too long, or the water pipe will break. Aluminum plastic pipe, PVC pipe can not use this method.
B hot water dissolving method: pour the frozen pipe into hot water (the temperature should be higher), especially at the elbow, until it dissolves. This method is "mild" and less likely to damage the water pipe, so this method is recommended.
Well, the above are the possible reasons for the lack of water in the hot water pipeline in winter and the solutions after the water pipe freezes. For more technical problems of water pipes and pumps, welcome to discuss with Shanghai Longya pump and valve technology department.
