老房子改造，如何将暖气改成地暖？

Old house transformation, how to heat the heating?

冬天将至，暖气也被慢慢使用起来。暖气是一种新技术，在当今社会用的越来越广泛了。暖气的初始温度一般都比较低，不会超过暖管里面热水的温度；暖气的工作原理遵守物理的定律，受到加热的物体，温度会升高，但是升高的温度远远没有初始的温度高。那么暖气改地暖怎么改？

The winter is coming, and the heat is also used slowly. Heating is a new technology. It is used more and more widely in today's society. The initial temperature of the heat is generally low and will not exceed the temperature in the warm pipe. The principle of the heating is observed by the laws of physics. The temperature will rise, but the temperature rising is far from the initial temperature. So how to change the heat to the ground heating?

暖气改地暖怎么改

How to change the heat to the earth

如果是新房子，相对来说比较简单，旧房子的话，就比较困难。

If it is a new house, relatively simple, the old house will be more difficult.

第一、要知道用户家里的暖气是否在用，是自己供暖（如自用燃煤锅炉、燃气壁挂炉等），还是集中供暖（小区模块锅炉、燃煤大锅炉、市政供暖等）。区分这个的原因是要搞清楚供水温度，暖气片的供水温度一般为80℃上下，而地暖只能使用低于60℃的水。如果使用壁挂炉，要调低供暖出水温度，如果是集中供暖，要加装自动混水装置，降低地暖供水温度。

First, to know whether the heating of the user's home is in use, it is their own heating (such as the use of coal fired boilers, gas wall hanging furnaces, etc.), or central heating (District module boilers, large coal fired boilers, municipal heating, etc.). The reason to distinguish this is to find out the water supply temperature, heating water supply temperature is generally about 80 degrees Celsius, and floor heating can only use water below 60 degrees Celsius. If wall-mounted furnace is used, the temperature of heating water should be lowered. If central heating is used, automatic mixing device should be installed to reduce the temperature of ground heating water supply.

第二、看用户家里的地面是否允许破坏，铺设地暖后室内地面将抬高10厘米左右，将妨碍防盗门、室内门的开闭。有两个处理方法：1、将需要破坏地面进行下挖，2、把所有门都换掉，重新定制。

Second, to see whether the user's home floor is allowed to destroy, the indoor floor will be elevated by 10 centimeters after heating, will hinder theft-proof doors, indoor doors open and close. There are two ways to deal with it: 1, we need to destroy the ground and dig down, 2, replace all the doors, and re customize them.

第三、地暖施工后，要重新做地面，比如铺地砖/木地板。

Third, after the construction of the floor heating, it is necessary to remake the floor, such as floor tile / wooden floor.

如果能确定以上两点，剩下的工作就很简单了。综上所述暖气片改地暖的费用会比较高，尤其是旧房，牵涉甚多，改造施工费用甚至高于同等条件下新房的地暖施工费用。

If we can confirm the above two points, the rest of the work will be very simple. In summary, the cost of heating the radiator will be higher, especially in the old house, which is much involved, and the cost of the renovation of the construction is even higher than that of the new housing under the same conditions.

地暖改造的三大要点

Three main points of the transformation of ground heating

一、暖气和地暖供回水温

1. Heating and heating to supply the temperature of the water

地暖是将温度不高于60℃的热水或发热电缆，暗埋在地热地板下的盘管系统内，再加热整个地面，通过地面均匀地向室内辐射散热的一种采暖方式。暖气的供回水温度一般是95/70℃，而地暖的供回水温度不高于60/50℃。如果整个小区是暖气采暖，只有单层用户想改装地暖，为确保加热盘管使用寿命，通常做法是在供回水进户处增设板式换热器或混水降温装置。这一装置的安装，能把采暖系统高温水置换成低温水，安装时切记不可直接将地暖管与采暖供回水管道相接。如直接相连，地暖管承载水温过热会致使管材损坏，影响地暖系统的寿命。

The ground heating is a heating mode that is buried in the coil system under the geothermal floor, reheating the whole ground and radiating heat evenly through the ground, which is not more than 60 degrees of hot water or heating cable. The temperature of heating and supplying water is generally 95/70 C, while the temperature of supplying and returning water is not higher than 60/50 C. If the whole area is heating heating, only one single user wants to refit the heating, in order to ensure the service life of the heating coil, the usual practice is to add the plate heat exchanger or the mixed water cooling device to the house for the return water. The installation of this device can replace the high temperature water of the heating system with the low temperature water, and it should be noted that the ground heating pipe should not be directly connected with the heating water supply and return pipe. If connected directly, the overheating of the ground heating pipe will cause damage to the pipe and affect the life of the floor heating system.

二、阻力平衡问题

Two, the problem of resistance balance

地暖的阻力比暖气大，约为暖气的十倍之多。在改装地暖时如果盲目在原暖气系统上增设加热盘管，可能导致暖气系统压力不足，热水难以循环，整个地暖系统难以正常运行散热。因此在改装时，建议增设混水恒温装置，通过循环泵强制循环。注意：如果增设混水装置时，由于难以估算原暖气系统阻力，选择的循环泵过大时，有可能会影响其他用户正常采暖。专家建议在循环泵增设一个旁通，如果阻力过大不能满足地暖系统时，可开启循环泵。

The resistance of floor heating is about ten times larger than that of heating. If the heating coil is added blindly in the original heating system, it may lead to the insufficient pressure of the heating system, the hot water is difficult to circulate, and the whole heating system is difficult to run normally. Therefore, in the modification, it is suggested to add a constant temperature device for mixing water and circulate through the circulation pump. Attention: if the water mixing device is added, it is possible to affect the normal heating of other users because it is difficult to estimate the resistance of the original heating system, and when the selected circulating pump is too large. Experts recommend adding a bypass to the circulating pump. If the resistance is too large to meet the floor heating system, the circulating pump can be opened.

三、地暖管盘不宜过长

Three, the tube plate should not be too long

地暖管盘越长，产生的阻力越大，运行时耗电越多。这就要求各个环路的长度不要相差太大，以免水力失调，造成有的环路热，有的环路不热。一般各个环路长度差不要超过10%，各管路以不超过120米为宜。

The longer the ground heating tube is, the greater the resistance is, and the more power it consumes. This requires that the length of each loop should not be too different, in order to avoid hydraulic imbalance, resulting in some loop heat, some loop is not hot. Generally, the length of each loop should not exceed 10%, and the pipeline should not exceed 120 meters.

暖气片的优势：1.继续使用暖气片组，无风险

Advantages of radiator: 1., continue to use radiator unit, no risk.

缺点：1.舒适性不及地暖；2.占空间，导致不能随心所欲摆放家具；3.不美观

Disadvantages: 1. comfort is not as good as floor heating; 2. occupies space, resulting in furniture not being placed as desired; 3. unsightly.

地暖优势：1.地暖温暖的脚感和舒适性；2.节省空间

Floor heating advantages: 1. floor warm feet and comfort; 2. save space.

地暖缺点：1.改造有潜在风险，所以我们找了口碑还不错的地康地暖；2.造价略高，目前和地康地暖谈好，加上分集水器和混水中心等等各种材料及人工费共8600元。

Ground warming and shortcomings: 1. transformation has potential risks, so we found a good reputation of the earth's good health, 2. cost slightly high, and the current and health to speak well, with the diversity of water and mixed water center and other materials and artificial costs of 8600 yuan.

暖气改地暖注意事项

Matters needing attention of heating and heating to ground heating

可以，但是有几个关键问题要注意：

Yes, but there are several key issues to be paid attention to:

1、供暖水的水温要调整：地暖的供暖水温最高为60℃，而使用暖气片的话，供暖水温一般要达到70℃以上才能比较适宜。

1, the water temperature of heating water should be adjusted: the heating water temperature of the floor heating is 60 degrees centigrade, and the heating water temperature is generally more than 70 degrees centigrade.

2、家里的墙壁有适宜挂暖气片的地方。

2, the walls of the home are suitable for hanging the radiator.

3、对于已经装修的房子，暖气片的管路连接势必会造成部分明管，有的甚至要穿墙打洞、门口翻高，这样对房间的装修会造成一定破坏。

3, for the house that has been decorated, the pipe connection of the radiator is bound to cause a part of the tube, and some even have to wear walls and holes, the door turn high, so that the decoration of the room will cause certain damage.
