What are the requirements for the installation and design of floor heating pipes in household floor

1) The temperature of floor heating water supply should not exceed 60;

2) The flow rate of hot water should not be less than;

3) There should not be more than 8 circuits of a distributor device;

4) The main water supply and return pipeline should be equipped with a globe valve or a ball valve. A filter should be set on the inside of the valve;

5) The length of each loop pipe should be as close as possible, not more than 90m, and the pipe spacing should not be greater than 300mm;

6) The thickness of the protective layer of cement mortar on the floor heating pipe should not be less than 20mm, and when the ground load is greater than 20kn m2, the protective layer should be reinforced with structural measures, generally with 6@300 steel mesh;

7) The interface of the combined matching fittings adopts staggered design, which is convenient for installation and pipe layout;

8) Add a lock nut between the mating valve and the main pipe.

Installing underfloor heating requires attention:

1.The problem of floor height, where there is no floor heating and where floor heating is installed, how to connect the floor height?

2.If there is a problem with the installation area, pay attention to the space under the fixed problem, especially for various cabinets and storage rooms.

3.Company selection, boiler selection, water separator selection, pipe selection, this depends on personal preference, mainly because of brand protection! But the price should also be right!

4.The positioning of the water separator and the concealment work in the future should be both good maintenance and beautiful.

5.The positioning of the control panel, to have enough space, to be thoughtful, sometimes the position of our customers when the initial positioning is enough, after the actual construction found that it is not enough, although it is very small but very critical

6。Acceptance: In addition to observing the pressure, you should also pay attention to the appearance inspection, some owners are very busy, but personal advice is to send someone to the site to take a look, don't wait for the cement leveling to see the pressure is over.

There are a lot of resources online, look for them.

In the north, in order to cope with the extremely cold winters, every household has installed underfloor heating. After the floor heating is installed, it must be decorated with the floor. However, not all floors are suitable for laying on top of floor heating, and floors that meet certain requirements can be used.

So, what are the requirements for flooring for floor heating? Let's introduce the four main requirements to Gu Zeheti, let's take a look!

1. The thickness of the floor for floor heating needs to meet the requirements to be thin.

The thickness of the floor for floor heating is as thin as possible, not more than 10mm.

2. The floor for floor heating needs to meet the requirements of Sun Shengpai's dimensional stability.

The dimensional stability mainly depends on the density of the substrate and the internal bonding strength of the floor, the higher the internal bonding strength, the better the ability of the floor to withstand temperature changes, and the phenomenon of cracking will not occur. Only the floor with a relatively dense substrate can ensure that it will not crack or deform at high temperatures for a long time. The size of the floor for underfloor heating should not be too large, the smaller the size, the better its stability.

3. The heat transfer of the floor for floor heating needs to meet the requirements quickly.

In order to achieve a better heat transfer effect, the floor for floor heating should be adhered to the ground, so that there will be no room for bacteria to survive, and the purpose of more environmental protection and prolonging the service life can be achieved.

Fourth, the floor for floor heating needs to meet the requirements of low formaldehyde content.

When consumers buy floors for floor heating, they must choose floors with low formaldehyde content as much as possible. Because the higher the temperature, the more formaldehyde will be released, and in a relatively closed room, it will cause indoor formaldehyde to exceed the standard, causing great harm to the human body.

1. Spiral pipe: This simple method can usually produce a uniform ground temperature, and can meet the special requirements of the local area by adjusting the pipe spacing, because the pipeline is only bent by 90° when using the spiral pipe, and the bending stress of the material is small, so we recommend this method.

2. Roundabout pipe routing: This method usually produces a high temperature at one end and a low end, and the pipeline should be bent by 180° when wiping, and the stress on the material is large, so we only recommend using it in a small space.

3. Mixed pipe routing: Due to the complex and diverse structure of the room, in addition to the above-mentioned typical pipe routing methods, the hybrid pipe routing method is also often used.

1. Spiral pipe routing: This method can usually produce a uniform ground temperature, and can meet the special requirements of the local simple destruction area by adjusting the pipe spacing, because the pipeline is only bent 90° when using spiral pipe routing, and the bending stress of the material is small, so we recommend this method.

2. Roundabout pipe routing: The temperature usually generated by this method is chaotic, the resistance end is high and the end is low, and the pipeline should be bent by 180° when wiping, and the stress of the material is large, so we only recommend using it in a small space.

3. Mixed pipe routing: Due to the complex and diverse structure of the room, in addition to the above-mentioned typical pipe routing methods, mixed pipe routing methods are also often used.

The installation of the supervisor must be paid attention to:

1. The installation of the supervisor must be constructed in the position indicated in the design drawings, and there shall be no error; (If it needs to be changed during the actual installation, please note the position of the supervisor on the drawing, provided that the designer's consent is obtained).

2. The supervisor must do thermal insulation;

3. The installation of the supervisor should be horizontal and vertical;

The installation of underfloor heating should be carried out in accordance with the construction steps and drawings. Among the things to note include:

1. The construction team you are looking for must be a construction team with professional knowledge of floor heating. As the saying goes, "three points of flooring, seven points of installation", the effect of the amateur decoration team is not worth guaranteeing.

2. Before paving the floor heating, we must check the tightness of the floor heating system.

3.The paved ground must be kept dry (which can be judged by experimental phenomena), and the moisture content of the cement floor should be lower than that; And the humidity in the room should not be too much, regardless of whether there is geothermal heating, we should ensure that the ambient humidity is about 60 degrees before and after installation.

4.It is strictly forbidden to nail on the ground during construction. After the construction of the home, it is also forbidden to nail the ground to prevent damage to the heating coil.

5.Before laying laminate flooring, we need to lay EPE composite film (and the EPE composite film must be marked with the words "underfloor radiation") to isolate moisture and release moisture from the surrounding skirting boards.

6.Do not lay the keel. We all know that the thermal conductivity of air is relatively small, and if the keel is laid, it may affect the heat dissipation effect and may damage the pipe.

7.When laying the floor, it is necessary to use special glue for floor heating, which can increase the time and effect of use, and there is basically no need to worry about the emission of harmful gases when using this glue.

8.Leave enough expansion joints between the floor and the wall, and use baseboards that are thicker than the current floor.

9.Paving the floor and installing the baseboard should be carried out in two phases. Wait 48 hours after laying the floor for the glue to dry completely, then remove the fastener before making the baseboards.

10.It takes 24 hours after installation to allow the floor to be heated.
