What's wrong with the floor heating? Full analysis of common causes and solutions

With the coming of winter, whether the floor heating is hot or not has become a focus issue for many families. This article combines the hot discussion data of the entire Internet in the past 10 days to systematically analyze the common reasons why the floor heating is not hot, and provide structured solutions.

1. Analysis of the popularity of floor heating issues across the entire network (last 10 days)

2. Six core reasons why floor heating is not hot

1.System is not vented: Air obstruction causes poor water flow, accounting for 42% of failure cases

2.clogged pipes: Scale deposition causes circulation obstacles, and the risk of not cleaning for more than 3 years reaches 67%

3.abnormal pressure: Heating efficiency drops significantly when the working pressure is lower than 0.8MPa

4.Temperature control failure: Problems caused by sensor failure or setting errors accounted for 18%

5.Installation defects: Pipe spacing is too large or circuit design is unreasonable

6.Heat source problem: The power of the wall-hung boiler is insufficient or the efficiency of the heat exchanger is reduced.

3. Structured solution comparison table

Failure performanceDetection methodSolutionsTools/Materials
Some rooms are not hotWater distributor valve temperature detection1. Exhaust operation
2. Adjust flow valve		Exhaust key, thermometer
Overall temperature is lowPressure gauge detects system pressure1. Hydration and boosting
2. Check circulation pump		Pressure gauge, water supply pipe
Slow heating rateCheck the combustion status of the wall-hung boiler1. Clean the filter
2. Professional descaling		Cleaning agents, professional equipment

4. Professional maintenance suggestions

1.Annual maintenance cycle: It is recommended that basic maintenance such as system exhaust and filter cleaning be completed every year before heating.

2.Deep cleaning standards: Systems that have been used for more than 3 years should undergo professional chemical cleaning, and the flow rate needs to be restored to more than 90% of the design value.

3.Pressure Monitoring Specifications: Under normal working conditions, the pressure should be maintained in the range of 1.0-1.5bar. If it is lower than 0.8bar, it must be dealt with immediately.

5. User self-examination flow chart

1. Check the thermostat settings → 2. Observe the pressure indication → 3. Test the temperature difference of the water distributor → 4. Check a single circuit → 5. Check the working status of the heat source

According to network maintenance data, about 65% of floor heating problems can be solved through user self-examination, and the remaining 35% require professional handling. It is recommended to give priority to troubleshooting simple faults before contacting after-sales service, which can save more than 70% of waiting time.

Note: The statistical period of this article is from December 1 to December 10, 2023, covering discussions on mainstream social platforms and professional home furnishing websites.
