Cleaning Floor Heating Pipes

1. Is it Necessary to Clean Floor Heating Pipes?

Floor heating systems involve extensive piping laid beneath the floor, through which hot water flows to provide heat. These pipes are relatively narrow and can carry impurities such as sediment, rust, and scale. Over time, these impurities can accumulate on the inner walls of the pipes, reducing the efficiency of the heating system and potentially causing malfunctions. Regular cleaning is essential to maintain optimal performance and prevent issues.

2. Floor Heating Pipe Cleaning Method

  1. Open the floor heating hot water inlet pipe.
  2. Pour the floor heating pipe cleaning solution into the pipe according to the instructions.
  3. Ensure the pipes are filled with water, close the cold water valve, and start the circulating pump for 30 minutes.
  4. Open the cold water valve and drain the turbid water.

3. Cleaning Frequency of Floor Heating Pipes

The accumulation of dirt on the inner walls of the pipes can reduce indoor temperatures by 3-5°C. Over time, this can worsen the heating efficiency and even cause blockages. It is recommended to have the geothermal pipeline professionally cleaned every 2-3 years to ensure proper maintenance and repair.

4. Important Considerations When Cleaning Floor Heating Pipes

  1. Always seek professional assistance for floor heating pipe cleaning to avoid damaging the system.
  2. During pulse cleaning, ensure that the sewage does not block the drainage system by installing sewage buffering equipment.
  3. Avoid unnecessary cleaning of newly installed floor heating systems if they are not blocked.
  4. It is normal for the temperature of cleaned floor heating systems to be initially low. The temperature will rise gradually, typically requiring about two days to reach normal levels.
  5. After cleaning, maintain the temperature at around 55°C to prevent rapid impurity accumulation.
  6. If the floor heating system will not be used for an extended period after cleaning, ensure that it is thoroughly dried to prevent freezing and cracking.

Maintenance of Floor Heating Pipes

1. Daily Maintenance Methods for Floor Heating Pipes

Avoid touching or striking the ground where the floor heating pipes are laid, and do not wedge any sharp objects into the floor. The pipes are only about 3-4 cm below the surface and can be easily damaged if not handled carefully.

2. Precautions for Maintaining Floor Heating Pipes

In addition to regular cleaning of the pipes, the entire heating system requires maintenance, including the heat source (such as a wall-mounted furnace), sub-collector, and water tank. Proper maintenance of the entire system ensures optimal performance and energy efficiency.
