Do we need to install insulation cotton on the pipes when installing radiators?
 
 

Regarding the installation of radiators, whether the heating pipes need to be insulated or not depends on the specific location of our heating pipes. Because different locations have different insulation requirements for pipelines, before answering this question, we need to understand the specific functions that pipeline insulation can play and which parts need to be insulated. Then I will explain to everyone whether installing radiators at home requires insulation for the pipes.

What are the functions of insulation for heating pipes?

For exposed heating pipes, the most commonly used insulation method at present is to wrap rubber insulation pipes on the outside of the heating pipes, and there are also some that wrap rock wool insulation pipes on the outside of the heating pipes. However, the use of rock wool insulation pipes is decreasing, and rubber insulation pipes are still the main choice. Rubber insulation for heating pipes can mainly serve the following three purposes.

① Prevent the hot water from dissipating heat during pipeline transportation. Because heating and hot water rely on exchange media to transfer heat during the transportation process.

For example, radiators rely on the material of the radiator itself to exchange heat with the inside and outside. For heating pipes, they can also rely on the material of the heating pipe to exchange heat with the outside world, which will cause the temperature of the water inside the heating pipe to decrease.

② It can avoid excessive temperature in non heating areas. Because many of our underfloor heating pipes pass through different areas, and for some areas, heating is not necessary. So for these areas, we must do corresponding insulation and heat preservation for the pipelines, so as to avoid the temperature rise in these areas.

For example, if some refrigerated areas pass through the heating pipes, effective insulation must be done.

③ To some extent, it prevents corrosion and rusting of pipelines. For exposed heating pipes, if they are exposed to outdoor environments for a long time, they are prone to corrosion and rusting. Especially in the case of rainwater corrosion, if we use galvanized pipes, they will quickly corrode? If we wrap the insulation and make it very tight, it can reduce the occurrence of pipeline corrosion.

Do you need to add insulation above the heating pipes when installing radiators?

We will provide two different answers regarding whether to add insulation to the installation of radiators and heating pipes. The first situation is that the heating pipes are purely indoor heating pipes for the heating area, while the second situation is that the heating pipes belong to outdoor non heating areas. So, for these two types of heating pipes in different positions, the following treatment points are given by Home Za Tan.

① The heating pipes of the radiators in the indoor heating area do not need to be insulated. Because our indoor space belongs to the heating area, when the heating pipes are not insulated, we can rely on the heat emitted by the heating pipes themselves to raise the temperature inside our room. This is also a good way to achieve indoor heating effect together with radiators. For example, in many areas where there are only heating pipes, the temperature in these areas is very high. So, at this point, we need to utilize the heat exchange function of the heating pipes.

② For the heating pipes in outdoor non heating areas, I personally recommend that everyone must do insulation. For example, if our heating pipes are connected from the outdoor corridor, we must ensure proper insulation for the exposed heating pipes inside the corridor. Because if we don't insulate this section of the pipeline, it will exchange heat with the outdoor air, causing a decrease in the temperature of the heating water entering our indoor environment. If the distance is long, it will cause a significant decrease in temperature.

③ For non heating areas indoors, insulation should also be done well. For many households, some areas do not have heating. For example, some rooms dedicated to storing items require strict temperature requirements and cannot have very high temperatures. Therefore, when heating pipes pass through such rooms, everyone must also do a good job of insulation for the heating pipes.

What should be paid attention to when insulating heating pipes?

The insulation of heating pipes is usually done later. After the pipeline installation is completed, we install insulation pipes on the pipeline. At this point, everyone must pay attention to the following three points

① : Material selection. For the heating and heating pipes we install ourselves, if we choose insulation materials, I personally recommend choosing rubber insulation pipes. Rubber insulation pipes are generally selected with a thickness of not less than 30mm, that is, insulation with a thickness of three centimeters, so that their insulation performance is very good.

② When installing rubber insulation pipes, it is necessary to choose the appropriate rubber insulation pipe according to the diameter of our pipeline. For example, a 20mm heating pipe must choose a 20mm rubber insulation pipe. Be sure to fasten the rubber insulation pipe to the heating pipeline during installation.

③ After installation, the rubber insulation pipe must be coated with special glue to seal the interface. That is to say, after attaching the rubber insulation pipe to the heating pipeline, we apply glue to the joint area, and then press the pixel insulation pipe tightly to seal the interface. Finally, use tape to seal the entire interface.
