2. Detailed steps for radiator installation
1. Preparation of tools and materials
| Category | Item list | Things to note |
|---|---|---|
| Tools | Impact drill, wrench, level, pipe wrench | Check battery charge/accessory integrity |
| Material | Radiator body, valve, pipe, bracket | Check whether the model matches the house area |
| Auxiliary materials | Raw tape, sealant, expansion screws | Give priority to high temperature resistant products |
2. Installation process (6 key steps)
①Positioning measurement: Use a level to determine the installation location, 10-15cm from the ground and 3-5cm from the wall.
②Drilling and fixing: Use an impact drill to install the expansion screws, ensuring that the horizontal error of the bracket is ≤2mm.
③Pipe connection: First install the water inlet and outlet valves, and wrap the raw material tape for more than 15 turns to prevent leakage.
④System water filling: Slowly inject water and exhaust, the pressure test needs to maintain 1.5 times the working pressure for 2 hours
⑤Debugging and testing: Check the leakage of each interface and test the sensitivity of the temperature control valve
⑥Beautify the edges: Use special decorative covers to cover the pipes, and be careful to leave access openings.
3. Answers to the 5 questions that netizens are most concerned about
| question | Professional advice | Related data |
|---|---|---|
| When does it need to be deflated? | When you hear the obvious sound of water flowing or the area is not hot | About 85% of poor circulation is caused by air blockage |
| What is the spacing between each set of radiators? | It is recommended to keep a distance of 50-100cm | Requires 80-100W cooling power per square meter |
| Can I change the direction of the pipeline myself? | Property reporting is required and modification of main pipes is prohibited | Fines for illegal renovations range from RMB 200 to RMB 2,000. |
4. Safety precautions
1. The main valve must be closed and the remaining water in the pipeline must be drained
2. The weight of a single set of cast iron radiators exceeds 20kg and requires the cooperation of two people
3. Prepare a water container to prevent splashing during the water injection test
4. The first temperature rise should be adjusted in steps (5°C per hour)
According to the latest research data, correctly installed radiators can increase thermal efficiency by more than 30%. It is recommended that after DIY installation, you make an appointment with a professional for final acceptance to ensure that the system is safe and reliable.
