What should I do if the floor heating pipe is blocked? ——A complete guide to causes, troubleshooting and solutions
As winter approaches, floor heating has become the main heating method for many families. However, clogged floor heating pipes can lead to reduced heating efficiency or even system breakdown. Among the floor heating failure issues that have been hotly discussed on the Internet recently, "pipe blockage" has become a high-frequency keyword. This article combines hot topics and technical discussions in the past 10 days to provide you with structured solutions.
1. Common causes of blockage of floor heating pipes
| Reason type | Specific performance | Proportion (whole network data) |
|---|---|---|
| Impurity deposition | Scale and rust accumulation | 42% |
| gas blockage | Gas accumulation in pipes | 28% |
| construction legacy | Debris left during installation | 15% |
| biological slime | Microorganisms grow to form sludge | 10% |
| Others | Pipe deformation, etc. | 5% |
2. Self-examination steps: quickly determine the blockage location
1.Observe temperature abnormalities: Use an infrared thermometer to detect the ground temperature. Areas with a temperature difference greater than 5℃ may be blocked.
2.Check the water distributor: If the temperature of the return pipe of a certain branch is significantly lower than that of other branches, the probability of blockage of this branch is high.
3.water flow test: Close other branch valves and test the water flow rate of the suspected blocked branch separately.
| degree of blockage | Water flow rate (L/min) | Handling suggestions |
|---|---|---|
| Mild | >1.5 | chemical cleaning |
| Moderate | 0.8-1.5 | Pulse cleaning |
| Severe | <0.8 | Physical dredging + high pressure washing |
3. Comparison of 5 mainstream dredging methods
| method | Applicable scenarios | Cost (yuan/㎡) | effectiveness |
|---|---|---|---|
| chemical cleaning | Scale/biological slime | 8-15 | ★★★☆ |
| Pulse wave cleaning | Moderate impurity clogging | 20-30 | ★★★★ |
| high pressure water jet | stubborn deposits | 35-50 | ★★★★★ |
| physical unclogger | Local hard object blockage | 15-25 | ★★★ |
| Full pipeline replacement | Severely aged pipes | 120-200 | Complete solution |
4. Three key measures to prevent blockage
1.Regular maintenance: Professional cleaning every 2-3 years (chemical + physical combination works best).
2.Install filter: Y-type filter can intercept more than 80% of impurities, and the filter needs to be cleaned every month.
3.water quality treatment
5. Emergency treatment plan
If there is a sudden blockage during the heating season, you can try:
① Close all branches and exhaust one by one
② Use a wrench to tap the pipe below the water distributor to promote the flow of impurities
③ Temporarily increase the water supply temperature (not exceeding 60°C) to soften the sediment
According to statistics from a home furnishing platform, 90% of floor heating pipe blockage problems can be solved through scientific cleaning. It is recommended to choose a professional organization with "Floor Heating Cleaning Service Certification" to avoid pipeline damage caused by violent cleaning. Do preventive maintenance in advance to ensure a warm winter!
