Can the main pipe from a water collector be used for floor heating coils?

The floor heating coil can use the main water collector pipe. The coils in an underfloor heating system transfer heat by circulating water. In the floor heating system, water enters the main pipe of the secondary water collector from the water supply pipe, and then enters each coil through the branch pipe. After the heat transfer is completed, it returns to the water collection pipe through the return pipe. , and finally returns to the heat source equipment for the reheating cycle. Therefore, the main pipe of the secondary water collector can be used as the water collection pipe for water supply and return, evenly distributing water to each coil, realizing supply and return water from the entire underfloor heating system.

Choice of underfloor heating battery: Is it better to use Poly or Watts ? Does an expert know?

Note

Generally, the standard distance between the floor heating coil and the wall is not less than 100mm, and the distance between the tubes is between 150 and 200mm. According to the "Floor Heating Installation Specifications", the spacing between floor heating pipes is generally 15-30cm, which is a reasonable phenomenon. If the floor height is too high, the spacing between the floor heating pipes should be sufficiently denser to ensure good performance of the floor heating installation. The spacing of floor heating coils is determined by a series of factors such as the heat load of the room, the temperature and temperature difference of the supply and return water, the layer and thickness of insulation, layer and thickness of filling, layer and thickness of decorative surface. The spacing betweenunderfloor heating pipes are implemented in accordance with the "Floor heating installation specifications". In domestic underfloor heating systems, the spacing between coils is usually designed to be 20cm. The spacing between cold walls and bay windows or floor-to-ceiling rooms. with poor thermal insulation performance is generally designed to be 15 cm. In industrial floor heating systems, the spacing between floor heating coils is usually 30 to 35 cm.

What material is best for floor heating coils? Does the color of the coil affect the heating effect?

The best floor heating pipes are Poly brand and imported premium brands. Domestic Mingshi PEX pipes have the same thermal conductivity as PERT pipes. The flexibility of PERT pipes is better than that of PEX pipes. The density of PEX pipes is higher than that of PERT pipes. are superior to those of PEX pipes. PERT pipes can be welded, but PEX pipes cannot. For floor heating pipes, it is recommended to choose PERT floor heating pipes

Answer: I think copper pipes are the best choice for heating coils through the ground, followed by plastic pipes, PERT pipes. have the best heat dissipation; the color of the coil will not affect the heating effect, but it will have environmental problems. Next, I will talk about this series of things based on my professional experience.

How to select materials for floor heating coils?

The function of the floor heating coil is to dissipate heat, and the required pipe material has the characteristics of good heat conduction. Since it involves heating, in accordance withx National heating design specifications and material standards, pipes with good heat dissipation, anti-oxygen penetration, high temperature resistance and no joints should be used. Plus, I think it should be easy to build. .

Therefore, metal pipes are the first choice for good heat dissipation, such as copper pipes, aluminum pipes, steel pipes, etc. Obviously, steel pipes are not corrosion resistant, joints are easy to leak, and they are not easy to construct and install. Aluminum pipes are also not corrosion resistant, and copper pipes are also not corrosion resistant, and construction is more difficult. All three have a flaw that it is not easy to build, which is why the metal pipes were eliminated first.

Amongplastic pipes, you can choose from PPR pipes, PE pipes, PB pipes and aluminum-plastic pipes. Among them, PPR pipes, PB pipes and aluminum-plastic pipes. cannot be disposed of without seals. Among them, aluminum-plastic pipes should not be used as buried pipes, so naturally these types of pipes are disposed of first, leaving only PE pipes.

PE pipes can be used in heating systems, including PERT and PEX pipes. What are the characteristics of these types?

PERT Pipe: This is a hot melt connected pipe. The hose is flexible and has good extensibility. There is an oxygen barrier layer on its surface to form an oxygen-resistant function, which can. Effectively prevents oxygen from entering the system through the pipe wall. Its advantages are good heat dissipation and f construction.acid. Its disadvantages are that it does not withstand high temperatures and the joints leak easily.

ButThe temperature of our floor heating is below 60 ℃, and the construction process does not require any joints, so this defect does not pose a threat.

PEX pipe, It can be mainly divided into three commonly used pipes: PEXC, pexa and pexb. Long story short, these are three pipes. only crosslinked. The result of different methods is that they all have the characteristics of high temperature resistance and can generally withstand water temperatures of 110 degrees when used in heating systems, they will also add a layer of barrier film to oxygen; the surface of the pipe, thus forming an anti-oxygenation function. The advantages of Pex pipes are resistance to high temperatures, long service life and the use ofHose sleeves to tighten the connection, making joints less likely to leak. The disadvantages are poor thermal conductivity, hard pipes and construction difficulties. .

What should you pay attention to when installing these two types of pipes in heating pipes?

Pert and PEX pipes are widely used in heating pipes. Naturally, these are pipes whose function is to prevent oxygen leaks. Among them, Pert is the most widely used in floor heating coils because it is simple to construct and affordable. good thermal conductivity. Since the pipe can only be connected by hot melt, once the pipe is damaged, the entire circuit pipe can only be replaced by certain people. During construction, the pipe wall is very thin. easy to disclose later.

Pexa and Pexb pipes are widely usedlized in the main heating water pipes; Pexc pipes are often used in coil pipes because they are white and everyone thinks they are very environmentally friendly. However, during their construction. , due to its own characteristics, the pipe will be fixed on the steel wire first, otherwise it will not be fixed using staples. Such a construction process is of course more expensive than using pert. Moreover, the cost of pexc pipes is inherently higher than that of pert, so the cost of these pipes is higher than that of pert.

Summary

Heating coils come from dispersed sources. From a thermal point of view, Pert pipes are preferred; from a construction point of view, Pert pipes are preferred; Of course, it is also possible to use pexc pipes. The article gives some precautions and understandings in their constructionnot. Finally, the color of the pipe will not affect its heat dissipation, but color is a way to judge the quality of the pipe.
