Geothermal installation options concrete filling precautions

The sound of the cold wind makes people tremble. The friends who live in the north have installed heating. In fact, the floor heating is also a good choice! Maybe there are many friends who don’t know yet. In fact, we usually say that the floor heating is It is called geothermal, and Xiaobian is popular for everyone! The floor heating is based on the entire ground as a radiator. Through the heat medium in the radiation layer of the floor, the whole ground is evenly heated. The floor heating uses the law of the ground's own heat storage and heat upward radiation from bottom to top. Conduct to achieve the purpose of heating. Do you know how to install the floor heating? Follow the small series to see the geothermal installation :

First, geothermal installation options:

1. Select floor heating materials

Choosing floor heating materials can be described as a large project. How can we choose the floor heating materials with high cost performance and reliable quality? The first choice of materials is very keywords, such as: water pipes, temperature control instruments, floor heating boilers, etc. . A good brand for after-sales and service.

2. Cost investment

Each floor heating equipment should comprehensively calculate the input cost and installation cost. Generally, the heating company will have a floor heating installation quotation. Users can refer to whether to choose the company.

3. Technology

After the user has determined the installation, the user should work side by side with the technician and the hydropower master in the shortest time. To achieve a reasonable and effective matching work, the floor heating can be installed normally.

4. Pipe slotting and punching

Before the main pipe and the flue are slotted and punched, the position of the previous hydropower concealed project and the person in charge of the owner and the decoration company are confirmed to avoid unnecessary damage to the previous hydropower concealed project.

5. Construction attention

The same construction operation surface does not cross-work with other types of work, so as not to affect the construction quality and the integrity of the equipment materials.

Second, concrete filling precautions

1. After the installation of the floor heating pipe is completed and the hydraulic pressure test is completed, the concrete filling layer is completed within 48 hours;

2. The construction of concrete filling layer shall be undertaken by a qualified civil construction party, and the unit shall cooperate closely;

3. During the construction of concrete filling layer, the water pressure in the heating pipe should not be lower than 0.6 MPa. During the filling layer curing process, the system water pressure should not be lower than 0.4 MPa;

4. The filling layer is a structural layer for protecting the plastic pipe and making the ground temperature uniform. Generally, it is bean stone concrete, the particle size of stone should not be more than 10mm, the volume ratio of cement mortar is not less than 1:3, and the concrete strength grade is not less than C15. The thickness of the filling layer should meet the design requirements, and the flatness is not more than 3mm;

5, the floor heating system needs to lay expansion joints at the vertical intersection of the wall, column, crossing door and the ground. The width of the expansion joint should not be less than 10mm. When the area of ​​the ground surface exceeds 30 m2 or the side length exceeds 6m, expansion joints and expansion joints should be set. The width should not be less than 8mm; the above expansion joints have been laid before the concrete filling layer is applied. When the concrete filling layer is constructed, care should be taken to protect the expansion joints from being damaged;

6. In the construction of concrete filling layer, it is strictly forbidden to use mechanical vibrating equipment; construction workers should wear soft-soled shoes and use flat-headed iron shovel. Floor heating - 10

Through the above introduction, I believe that everyone has a certain understanding of the installation of geothermal heat and the matters needing attention during installation. If you want to install geothermal heat, you must read this article in a small series. The help for you is very big! If you want to know more about decoration, please continue to pay attention to the decoration home network.
