Floor heating installation diagram four steps to install floor heating

China Security Network Xiaobian below focuses on the floor heating installation diagram, I hope to help friends who want to install floor heating!

First, the floor heating installation diagram step 1

Preparation - Prerequisites for floor heating construction

1. The design drawings and other technical documents are complete and have been reviewed.

2. The approved construction plan or construction organization design has been exchanged and passed.

3. Construction forces and institutions with construction qualifications can guarantee quantitative construction.

4. Preparation work on the construction site: the wall has been plastered, the ground leveling layer has been done; temporary facilities such as construction water, electricity, material storage and release sites.

5. According to the design requirements, the inspection of pipes, pipe fittings and supporting materials meets the requirements.

Floor heating construction procedures and technical requirements

1. Laying insulation materials on the ground that has been leveled, the laying should be smooth and tightly connected. Except for the plastic staples of the fixed heating pipe, there must be no other damage.

2. Lay the reflective layer of polyester film or reinforced aluminum foil (can be prepared or laid on site).

3. Supporting and laying of heating pipes:

Discharge the line according to the design drawings (if the reflective film has been printed, this item can be exempted), and the piping (if it has been supplied according to the design length, this item can be exempted). The bending radius of the heating tube should not be less than 8 times the outer diameter of the tube. No joints are allowed in the filling layer and the heating tube is fixed (there are three methods to fix). The distance between the fixing points of the heating pipe is 700mm for the straight pipe and 350mm for the curved pipe. There should be five fixed clamps at the corner of 180°C.

4. Installation of heat medium gathering device (water separator):

It can be fixed in the wall or special box. Generally, the water separator should be installed under the water collector, the spacing should be 200mm, and the water collector should not be less than 500mm from the ground.

5. The heating pipe is connected with the collecting device:

A dedicated clamp connection or a ferrule connection is available. At the end of the heating pipe, an insulated casing shall be provided to prevent the local ground temperature from being too high.

6. After the heating tube and the collecting device are firmly connected, each channel should be flushed one by one until the water is clean.

7. In conjunction with the construction unit, the filling layer must be filled with water pressure (pressure ≮ 0.6Mpa), pay attention to the expansion joint construction, the heating pipe extrusion, the pebble concrete pouring and so on.

Acceptance of floor heating construction works

Acceptance is divided into intermediate acceptance and completion acceptance:

The intermediate acceptance shall be carried out by the construction unit in conjunction with the construction supervision unit of the construction unit.

The completion acceptance shall be organized by the competent authority for construction, design, supervision, construction and related units.

A. Intermediate acceptance: The intermediate acceptance process starts from the installation of the heating pipe laying and the heat collecting device, and the pressure is applied again until the concrete filling layer curing period.

1. Self-test pressure test:

After the heating pipe and the collecting device are completed, they shall be self-tested once according to the specified pressure (generally 0.8MPa).

2. Intermediate acceptance test:

The test pressure should not be less than the system static pressure of 0.3 MPa, and not less than 0.6 MPa, should be strictly in accordance with the pressure test operation.

3. In the winter water pressure test, reliable anti-freezing measures should be taken, or the air pressure test should be carried out with the consent of the construction unit and the supervision department.

B. Completion acceptance:

1, should have the conditions:

Construction drawings, as-built drawings and design change documents; main materials, product ex-factory certificate (or inspection records); intermediate acceptance records; engineering quality inspection and evaluation records.

2. Completion acceptance is carried out for 24 hours, warming for 24 hours, and then warming for 24 hours.

The first warming should be slowly warmed up. The hot water temperature should be controlled within the range of 25 ° C to 30 ° C for 24 hours, and then the temperature should be increased by 5 ° C every 24 hours until the design water temperature is reached.

C. Intermediate acceptance and completion acceptance should be recorded, signed and archived.

Floor heating installation project is prone to problems

Since the floor heating is achieved by means of a plastic pipe concealed under the floor, it is difficult to cope with the heating effect after the completion of the entire laying process, or if maintenance is required.

In view of the above hidden dangers, the choice of floor heating is for the sake of once and for all, convenient and comfortable, so we must remind the users who want to install floor heating, do not forget to protect their legitimate rights and interests while pursuing the trend of floor heating, and first consult in the installation process. Coordination, signing contracts, pay attention to the construction details and the use of related accessories during the installation project, and supervise them to avoid the trouble caused by the convenience of drawings and the drag of engineering problems.

Precautions:

Regardless of the choice of product or installation company, in order to ensure the quality of your floor heating installation and use, the following principles should be followed when selecting:

First of all, we must choose a professional floor heating company. Floor heating systems are more complex, from design to product selection; from construction and installation to after-sales service, the overall effect will be greatly reduced without the participation of professionals. Therefore, choosing a professional floor heating company is the most critical guarantee.

Second, we must select companies with rich construction experience. The warmth effect depends largely on the quality of the construction. The experienced floor heating company can select the most reasonable construction plan according to the structure, orientation and layout of the user's room, so as to achieve a reasonable distribution of heat energy.

Third, choose a pipe with excellent performance. Floor heating is a concealed project, and the quality of the pipe directly affects the quality of the entire project.

Finally, it is necessary to select insulation materials with excellent performance. When the insulation effect is good, it will save energy. If the insulation effect is not good, it will waste energy.
