How to learn underfloor heating installation 5, how to learn underfloor heating installation

There are several steps to learn how to install underfloor heating:

1. Install the water collector: install the water collector against the wall according to the pre-demarcated position, and the installation should be straight and firm.

2. Connect the main water pipe: the main pipe should maintain a slope of 3%, install the fixed bracket or drop the card at a certain distance, and complete the installation and acceptance for thermal insulation; The arc of the coil at the position of the separator should not exceed 90 degrees.

4. Laying extruded plastic board: first cut the insulation board according to the actual size, and then lay, leaving a gap for the pipeline when laying; The gap between the plates is not more than 5mm, and the gap is not more than 5mm.

5. Laying the reflective film: the reflective film must be close to the insulation board, and the edges of the two reflective films must also be glued with tape.

6. Laying floor heating pipes: laying floor heating coils in strict accordance with the design and construction drawings, and fixing the pipes on the insulation layer with plastic nails.

7. Backfill leveling ground: backfill fine stone concrete, and the cushion should be manually compacted, and it is not allowed to use mechanical vibration or step on the laid pipeline.

8. All these steps are reasonably arranged, hopefully.

This is simple, first of all, to understand how it works. You can see the specific construction at a glance at the site.

In fact, if you look for this knowledge in the library, there are some professional things that should be useful. There are also books from bookstores that you can also study. It's better to find a friend who understands it, so that you can learn faster.

Floor heating is divided into two kinds: water floor heating and electric floor heating, the floor heating heated by hot water is water floor heating, and the floor heating heated by cable electric heating film is electric floor heating. The principle of floor heating is to heat the ground, through the ground heat conduction and.

I can't tell you for a while, you can go to the forum or something, and look at the on-site construction drawings.

Underfloor heating is a concealed low-temperature radiant heating system installed underground, which can provide a comfortable indoor temperature and a healthy way to heat the room. How do you need to install floor heating? The steps for installing underfloor heating are roughly as follows:

1.Level the ground. Before construction, it is necessary to ensure that the civil ground wall has been completed, and the foundation has been leveled, and there is no other type of work in the site.

Check the flatness of the ground with a level, and the height difference within 1 meter is less than or equal to 5 mm. The protruding part of the wall or ground is removed with a shovel, and the ground groove is filled with concrete.

2.Install a manifold. The manifold is an important part that connects the boiler and the piping, and it can control the flow and temperature of each circuit.

The manifold should be installed horizontally at a certain height from the ground, and the protective bender should be used to fix and protect the ground coil in the part of the pipe entering the ground from the manifold.

3.Laying insulation. Insulation prevents heat from being lost downwards and improves heating efficiency.

The insulation material should cover the entire construction area and fit tightly with the wall. Toilets or floors that are in direct contact with the soil or have moisture gas invasion should be covered with a waterproof layer or a moisture-proof membrane.

4.Laying underfloor heating pipes. The floor heating pipe is the main carrier of heat transfer, it should be evenly distributed on the ground and leave a certain distance from the wall.

The distance between the pipes between each circuit and the circuit length should not exceed 20m to ensure even heat distribution. When laying, care should be taken to avoid damaging the pipeline, and the pipe should be fixed with steel wire mesh.

5.Hydrostatic test of pipelines. The hydrostatic test is an important part of checking whether the pipeline has water leakage, blockage, deformation and other problems.

During the test, the boiler and manifold should be isolated, and all circuits should be opened, and then the pipeline should be pressurized and stabilized with professional equipment until the design pressure is reached and stabilized for a period of time.

6.Backfill leveling the ground. Backfill leveling is the process of burying pipes in concrete and bringing the surface layer to the desired height and flatness.

When backfilling and aligning, pay attention to protecting the pipeline and monitor the pressure change of the pressure gauge. If there is a harsh environment during construction in winter, the water in the tunnel should be drained to avoid freezing and damaging the pipeline.

Underfloor heating is now a popular heating method, because the heating effect is very good, and it is generally used in the colder winter in the north. But many people don't know much about the installation of floor heating systems, so what are the specific steps for the installation of floor heating systems? First of all, it is necessary to install a manifold, which is a very important place to control the temperature, and secondly, to remove debris from the ground before construction.

The most important place is to install the pipes for floor heating, and this step must be careful when constructing. Finally, it is enough to lay the insulation layer, and it is best to test the pipeline first, so that it can be put into use!

First, the installation of the manifold floor heating system The first step of installation is to install the manifold, determine the location and elevation according to the actual use, and then install it. It can be fixed with expansion screws, and in order to prevent heat loss, a special protective sleeve can be installed on the section of pipe that connects the manifold to the room. Finally, install the two ends of the pipeline!

2. Remove the debris on the ground before construction, clean up the indoor ground first, ensure the smoothness of the ground, and eliminate all debris. Then measure and inspect the area of the room, and determine the installation location of all wall-hung boilers and manifolds, and then proceed to the following steps!

3. Installation of floor heating pipes The most important step in the installation of floor heating systems is to install floor heating pipes. When laying floor heating pipes, it is necessary to carry out the overall construction according to the pipe spacing and direction calibrated in the drawings. Keep it straight and secure.

It should be noted that the location of the main water pipe must be the use of hot water pipes. PP-R or aluminum-plastic pipes can be used, which will be safer!

Fourth, laying the insulation layer After all the pipes are laid, the last step of the floor heating system installation can be carried out. After laying the insulation layer, it is necessary to pay attention to keep it flat and cut neatly, which can be more convenient for construction. Also keep the seams tighter, the height difference should not exceed 5mm, and the gap should not exceed 5mm!

That's all for the installation of floor heating systems! Floor heating installation is the need for professionals to carry out the construction, if you want to do your own construction, you must first understand the relevant knowledge!

The steps for laying underfloor heating are as follows:

1.Level the ground first. Floor heating construction has requirements for the flatness of the ground, and the flatness of the original ground before the floor heating is laid needs to reach a drop of less than 2 cm (2 meters of ground height difference by the ruler), so as to ensure that the floor heating insulation board can be laid at the same flatness and will not be dented.

2.Then install the water collector and separator, install it horizontally in the designated position, the water separator is on the top and the water collector is below, keep the spacing of 200 mm, and keep the water digging branches.

3.Paving insulation boards. For the general thickness of the insulation board, we will use a white crystal plate with a thickness of 2 cm, and its load-bearing capacity must be at least not less than 35 kg; If the height of the space is sufficient, we can choose a 3 cm thick insulation board.

And set up shrinkage joints according to the requirements, in addition, all the insulation belts along the wall of each floor heating area should be done, and they can not be omitted or set up randomly.

4.Pipeline water pressure test: inject cold water into the paved pipeline, after the pipeline is filled with water, then use a special press machine to inject 10kg of pressure, seal for 24 hours, if the pressure of the pipeline is not less than 6kg at this time, it means that the pipeline has no leakage and can be used normally.

5.Backfill leveling ground: the general floor heating project is to use cement mortar to smooth it, the ground height difference after concrete leveling shall not be greater than 5mm, and the horizontal line of the whole house must be at a height.

When laying concrete, it must be marked at the door, aisle, floor drain and other locations to prevent improper behavior in the later construction from damaging the floor heating pipes.

Floor heating is a widely used heating tool now, but many people don't know much about floor heating. So what does underfloor heating look like? It has many benefits that can help people not suffer from the cold air in the cold winter, so that people do not have to be wrapped like bears at home, and at the same time, it can greatly improve people's living experience.

And the heat he provides to people is very even, so that everyone will not feel warm and hot. The first step to understand floor heating is to understand its installation process, and the following will introduce you to how to install floor heating.

Before installing floor heating, the ground should be dealt with, in this step, what we have to do is to clean the ground, try to keep the ground level, and remove the uneven places, which is also the preparation for the installation of floor heating.

Generally, when installing floor heating, the design drawings will show the installation position of the master control system, and we only need to install the master control system at the specified location according to the drawings. However, it should be noted that the water separator is on top of the water collector, and the protection of the water separator must also be done.

As the name suggests, the laying of the dry temperature layer and the reflective film is to prevent heat loss, so this step must be done well. The insulation layer and the reflective film must be laid flat, and the seams of the insulation layer must be pasted firmly.

It is good to lay the floor heating coil according to the steps given in the construction drawings, but pay attention to the pipe must be cleaned in advance, and try to choose the thick and high-quality floor heating pipe, which can increase the service life of the floor heating, because the maintenance of floor heating is very difficult to do.

Once you've completed the above steps, check the floor heating to see if it's working properly, or if there are any holes, such as water leaks, etc. It's a great way for everyone to understand what underfloor heating is like.

This is how the installation process of floor heating is, but this is only the first step to understand what floor heating is, to further understand what heating is, but also to analyze its advantages and disadvantages and development process, etc., but we don't have to worry too much about this problem, ordinary people do not know what floor heating is also not affected.
