Floor heating has become a popular choice among homeowners due to its comfort and convenience. Integrating it during the renovation process can save a lot of future hassle. However, beyond selecting high-quality materials, proper installation is equally important. To ensure a smooth and efficient system in the long run, it's essential to follow the correct installation procedures and standards. Here’s a detailed guide on how to install floor heating properly.
**First, Preparations – Essential Conditions for Floor Heating Installation**
1. Ensure that all design drawings and technical documents are complete and have been reviewed.
2. The construction plan or organization design must be approved and thoroughly discussed with the team.
3. Only qualified personnel and agencies should carry out the work to guarantee quality and efficiency.
4. Prepare the construction site: walls should be plastered, floors should be screeded, and temporary facilities like water, electricity, and storage areas must be ready.
5. Inspect all pipes, fittings, and materials according to the design specifications to ensure they meet the required standards.
**Second, Construction Procedures and Technical Requirements**
1. Lay insulation material on a level ground. Make sure it is smooth and tightly lapped, using plastic staples only where necessary to secure the heating pipes.
2. Install a polyester film or reinforced aluminum foil reflective layer, either pre-made or installed on-site.
3. Laying the heating tubes:
- Follow the design layout. If the reflective film is already marked, you can skip this step.
- The bending radius of the heating tube should not be less than 8 times the outer diameter.
- No joints should be present within the filling layer, and the pipe must be fixed using three methods.
- For straight pipes, fix every 700mm; for bent pipes, every 350mm. At 180-degree bends, use five fixing clamps.
4. Install the heat medium collection device (water separator):
- It can be mounted on the wall or in a special box. The spacing between the water separator and collector should be 200mm, and the collector should be at least 500mm above the ground.
5. Connect the heating pipes to the distribution device using a dedicated clamp or a card sleeve. Add insulation sleeves at the ends to prevent overheating.
6. After connecting, flush each channel until the water runs clean.
7. Coordinate with the construction team for the filling layer. The water pressure system must be maintained at no less than 0.6MPa, and attention must be paid to expansion joints and concrete pouring.
**Third, Acceptance of the Heating Project**
The acceptance process includes both intermediate and final inspections. The intermediate inspection is conducted by the construction company and the supervising unit, while the final inspection involves the construction authority, design, supervision, and construction teams.
**A. Intermediate Acceptance:**
- Starts after the heating pipe and collection device are installed and pressure-tested.
- Self-test pressure: After installation, check the pressure (usually 0.8MPa).
- Middle acceptance test pressure: Should not be less than 0.3MPa (static pressure) and not below 0.6MPa.
- During winter testing, take anti-freezing measures or use air pressure tests with approval from the construction and supervision units.
**B. Final Acceptance:**
- Required documents include construction drawings, as-built drawings, design changes, product certificates, intermediate acceptance records, and project evaluation reports.
- Conduct inspections during a 24-hour warm-up period. Start with a slow warm-up, keeping the water temperature between 25°C and 30°C for the first 24 hours, then increase by 5°C every 24 hours until reaching the design temperature.
- All acceptance processes must be documented, signed, and archived.
**Editor's Note:** Floor heating installations are complex and prone to issues if not done correctly. It's crucial to choose a reliable service provider to avoid future problems. Since the system is hidden beneath the floor, any mistakes or poor maintenance can lead to costly repairs.
When choosing a heating system, it's important to protect your rights and ensure quality. Always consult professionals during the installation process, sign a clear contract, pay attention to details, and supervise the work to avoid future complications.
**Key Tips for Warming Construction Projects:**
- Choose a professional heating company. A well-designed and properly installed system requires expert involvement from start to finish.
- Select companies with extensive experience. Experienced contractors can tailor the system to your home's layout and structure for optimal performance.
- Opt for high-performance pipes. As a hidden project, the quality of the pipes directly affects the system's longevity and efficiency.
- Use high-quality insulation materials. Good insulation ensures energy efficiency and reduces waste.

Continuous basalt fiber (abbr. CBF) is a continuous fiber made of natural volcanic extrusive rock as the exclusive raw material. After melting at 1450-1500℃, continuous basalt fiber is manufactured by special technology. Basalt fiber is high performance non-metallic inorganic fiber, which has unique excellent properties in tensile strength, high and low temperature resistance, corrosion resistance, heat insulation, sound insulation, flame retardant, chemical resistance and electrical insulation.
