How is floor heating installed?
As an efficient and environmentally friendly heating method, geothermal systems have been favored by more and more families in recent years. This article will introduce in detail the installation process, precautions and related data of the geothermal system to help you fully understand the details of geothermal installation.
1. Introduction to geothermal system
The geothermal system is a way to achieve heating by evenly transferring the heat from hot water or electric heating cables to the room through pipes buried under the floor. Its advantages are energy saving, comfort and not occupying indoor space.
2. Geothermal installation process
The installation of a geothermal system is mainly divided into the following steps:
| steps | content | Things to note |
|---|---|---|
| 1. Design planning | Design pipeline layout according to house area and structure | Heat load and zoning control need to be considered |
| 2. Ground treatment | Clean the floor and lay insulation and reflective films | Make sure the ground is flat and dry |
| 3. Pipe laying | Lay geothermal pipes or electric heating cables according to design drawings | Pipes should be evenly spaced to avoid crossing |
| 4. Stress testing | Water injection and pressure testing to detect pipe tightness | The test pressure needs to reach 1.5 times the working pressure |
| 5. Filling layer construction | Pouring concrete to cover pipes | The thickness is usually 3-5cm and needs to be dried naturally. |
| 6. Floor decoration | Laying floor or tiles | Choose materials with good thermal conductivity |
| 7. System debugging | Start the system and adjust the temperature | Need to warm up slowly for first time use |
3. Key data for geothermal installation
The following are the technical parameters that need to be paid attention to during geothermal installation:
| parameters | Standard value | Description |
|---|---|---|
| Pipe spacing | 15-30cm | Adjust according to heat load and zone |
| Water supply temperature | 35-55℃ | The maximum temperature does not exceed 60℃ |
| System working pressure | 0.3-0.5MPa | Test pressure is 0.6-0.8MPa |
| Filling layer thickness | 3-5cm | Too thin affects heat storage, too thick reduces efficiency. |
| Heating rate | 5-10℃ every day | Need to warm up slowly for first time use |
4. Precautions for geothermal installation
1.Choose the right installation time: It is recommended to carry out geothermal installation in the early stage of decoration to avoid conflicts with other projects.
2.Material selection: Pipes should be made of PEX or PERT pipes that are resistant to high temperatures and corrosion, and high-density extruded boards should be used as the insulation layer.
3.Partition control: It is recommended to divide the house into different temperature zones and control each zone independently to improve energy efficiency.
4.Professional construction: The geothermal system has high requirements for construction technology. It is recommended to choose a qualified professional company for installation.
5.Later maintenance: Regularly check the system pressure and clean the pipes every 2-3 years to ensure efficient operation of the system.
5. Advantages of geothermal systems
1.High comfort: Heat rises evenly from the ground, ergonomically designed.
2.Energy saving and environmental protection: It saves 20%-30% energy than traditional heating and reduces carbon emissions.
3.save space: Concealed installation, does not occupy indoor space.
4.Long service life: High-quality geothermal systems can last more than 50 years.
6. Summary
The installation of a geothermal system is a systematic project that requires professional design and construction. Through the introduction of this article, I believe you will have a more comprehensive understanding of geothermal installation. Be sure to pay attention to technical details during installation and choose high-quality materials to ensure long-term stable operation of the system.
With the improvement of environmental awareness and the development of technology, geothermal heating will surely become one of the mainstream choices for home heating in the future. It is recommended to consult professionals before installation to develop the most suitable installation plan based on the actual situation of the house.
