How to wash the filter for floor heating
With the advent of winter, floor heating has become the main way of heating many homes. However, the problem of filter cleaning in floor heating systems is often ignored, resulting in reduced heating efficiency and even equipment damage. This article will introduce in detail the cleaning method of the floor heating filter, and attach relevant data to help you easily complete this maintenance work.
1. Why do you need to clean the floor heating filter?

The main function of the floor heating filter is to filter impurities in the pipes and prevent blockage. After long-term use, the filter will accumulate a large amount of dirt, affecting the water flow rate and thus reducing the heating effect. The following are common effects of clogged filters:
| Impact type | Specific performance |
|---|---|
| Decreased heating efficiency | The room temperature is difficult to reach the set value |
| Increased energy consumption | Significant increase in electricity or gas bills |
| Shortened equipment life | Water pumps and other components are damaged due to overloading |
2. Steps to clean the floor heating filter
Cleaning the floor heating filter is not complicated, just follow the steps below:
1. Turn off the floor heating system
Before cleaning, be sure to turn off the power and water source of the floor heating system to ensure safety.
2. Find the filter location
The floor heating filter is usually located near the water inlet of the water distributor. Please refer to the equipment manual for the specific location.
3. Remove the filter
Use a wrench or special tool to unscrew the filter cover and take out the filter. Be careful not to use excessive force to avoid damaging components.
4. Clean the filter
Rinse the filter with clean water and scrub gently with a soft-bristled brush if necessary. If the dirt is stubborn, soak it in neutral detergent and then rinse.
5. Check filter status
After cleaning, check whether the filter is damaged or deformed. If the damage is serious, it is recommended to replace the filter with a new one.
6. Reinstall the filter
Put the cleaned filter back into place and tighten the filter cover to ensure tightness.
7. Restart the system
Turn on the water source and power supply, and check whether the system is operating normally and whether there is any water leakage.
3. Cleaning frequency recommendations
Depending on the use environment and water quality, the cleaning frequency also varies. The following are recommended cleaning cycles:
| Usage environment | Recommended cleaning frequency |
|---|---|
| Areas with better water quality | Clean every 1-2 years |
| Areas with poor water quality | Clean every 6 months |
| Newly installed floor heating system | Clean 3 months after first use |
