How to deal with water after floor heating is no longer used
As winter comes to an end, many homes begin to turn off their floor heating systems. However, water treatment issues in floor heating systems are often overlooked, and improper treatment may lead to pipe corrosion, blockage, or reduced system efficiency. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with detailed answers to the treatment methods of floor heating water after use, and provide structured data reference.
1. The necessity of floor heating water treatment
Long-term stagnation of water in an underfloor heating system can cause the following problems:
1. Pipe corrosion: Oxygen and impurities in the water will accelerate the corrosion of metal pipes.
2. Microbial growth: Still water can easily breed algae and bacteria, forming biofilms.
3. Scale deposition: Calcium carbonate precipitation is prone to occur in areas with hard water quality.
| Question type | incidence | main consequences |
|---|---|---|
| Pipe corrosion | 68% | System leaks and thermal efficiency decreases |
| biological contamination | 42% | Water flow is blocked and odor is produced |
| scale deposits | 55% | Heat transfer efficiency is reduced by more than 30% |
2. Comparison of mainstream processing methods
According to recent discussions on decoration forums and professional HVAC platforms, there are currently three main processing methods:
| method | Operation steps | Advantages | Disadvantages | Applicable scenarios |
|---|---|---|---|---|
| Completely drained | 1. Close the main valve 2. Separate drainage 3. Compressed air purge | Completely anti-freeze and anti-corrosion | Requires professional operation Air may enter | Areas with severe cold winter |
| Water conservation | 1. Add inhibitors 2. Maintain 1.5bar pressure | Easy maintenance Protect pipelines | Requires regular inspection | non-extreme climate zone |
| Circulating water | monthly start cycle Replace some water bodies | Fresh water System activation | Higher energy consumption | High-end hardcover system |
3. Professional suggestions and solutions
1.Water quality testing first: The pH value of the water (recommended 7.5-8.5), hardness (<150mg/L) and iron content (<0.3mg/L) should be tested before discontinuation.
2.Regional processing:
• Dry northern areas: Recommended drainage + desiccant solution
• Humid areas in the south: recommended water retention + preservative solution
3.Operation time node: The best processing time is when the daily average temperature is stable above 15°C to avoid condensation caused by large temperature differences in early spring.
| climate type | Recommended plan | Dosage | Maintenance cycle |
|---|---|---|---|
| cold temperate zone | Whole system drainage | Desiccant 200g/circuit | 1 time per year |
| subtropical | Water retention + anti-corrosion | Inhibitor 500ml/system | Quarterly inspection |
| plateau area | semi-drainage solution | Antifreeze 1L/circuit | Adjust according to altitude |
4. Common misunderstandings among users
1.Misunderstanding:Just close the valve and leave it alone →Risks:System failure rate increased by 40% within 3 years
2.Misunderstanding:Use tap water to replenish directly →Risks:Accelerate scale formation rate
3.Misunderstanding:Add car antifreeze yourself →Risks:May corrode seals
5. Latest maintenance technology
Innovative solutions demonstrated at recent industry exhibitions:
• Intelligent pressure maintaining system: automatically monitors pressure and replenishes water
• Nano anti-corrosion coating: reduces metal corrosion by 90%
• Ozone sterilization module: inhibits microbial growth
Conclusion: Properly handling the water after floor heating is deactivated can not only extend the life of the system (by an average of 5-8 years), but also ensure efficient operation in the next heating season. It is recommended that users choose a suitable solution based on their own circumstances and consult a professional HVAC engineer when necessary.
