How to adjust whether the floor heating is not hot: Solutions to the most popular problems on the Internet in the past 10 days
As the temperature drops sharply in winter, whether the floor heating is hot has become a hot topic on the Internet recently. Many users report that the floor heating effect in their homes is not good. The following is a structured solution based on the content of high-frequency discussions across the Internet in the past 10 days.
1. Analysis of common causes of insufficient floor heating
| Question type | frequency of occurrence | Typical symptoms |
|---|---|---|
| clogged pipes | 38% | Some rooms are not hot/heat up slowly |
| Not enough pressure | 25% | The overall temperature is not up to standard |
| Thermostat failure | 18% | Display is abnormal/cannot be adjusted |
| water separator problem | 12% | Single path without circulation |
| Not exhausted after first use | 7% | There is a sound of water flowing in the pipe |
2. Step-by-step investigation and adjustment methods
Step 1: Check basic settings
1. Confirm that the thermostat temperature setting is more than 3°C higher than room temperature.
2. Check the system pressure gauge (1.5-2Bar is the normal range)
3. Check whether the wall-hung boiler ignites normally (observe the flame icon)
Step 2: System exhaust operation
| Device type | Exhaust position | Operational points |
|---|---|---|
| water separator | exhaust valve | Turn counterclockwise until water comes out without bubbles |
| wall mounted boiler | Automatic exhaust valve | Press 3-5 times until the water flow is stable |
| piping system | highest valve | Need to cooperate with water pump operation |
Step 3: Adjust hydraulic balance
1. The flow regulating valve of the water distributor decreases the flow clockwise and increases the flow counterclockwise.
2. Typical room traffic distribution suggestions:
- Master bedroom: fully open (100%)
- Living room: 3/4 opening
- Bathroom: 1/2 opening
3. Key points for adjusting equipment of different brands
| brand | Special function keys | reset operation |
|---|---|---|
| Power | Press and hold the "i" key for 3 seconds | Power button + Confirm button for 5 seconds |
| Bosch | Mode key pressed continuously | Requires special reset tool |
| little squirrel | Snowflake/sun icon toggle | Unplug the power and restart after 5 minutes |
4. Judgment Standards for Professional Maintenance
It is recommended to contact professionals when the following situations occur:
1. After adjustment, there are still many groups of pipes that are not hot.
2. Wall-hung boilers frequently report errors (codes such as E1/E4)
3. System pressure continues to drop (pressure drop exceeds 0.5Bar in 24 hours)
4. There is obvious leakage in the metal parts of the water distributor
5. Auxiliary improvement plans that have been hotly discussed recently
1.Install circulation pump: Applicable to duplex/large flat floor units (discussion popularity ↑120%)
2.Duct cleaning services: The first choice for users who have not maintained maintenance for more than 3 years (Meituan data shows that order volume increased by 75%)
3.Intelligent temperature control upgrade: Mobile APP remote control has become a new trend (JD Double 12 sales increased by 200% year-on-year)
Things to note:
1. Exhaust operation must be performed when the system is cooled down
2. It is recommended to use a special expansion tank when replenishing pressure.
3. The first use should keep running continuously for 48 hours.
4. Users of solid wood flooring are advised that the surface temperature should not exceed 28°C.
Through the above structured investigation method, 90% of floor heating problems can be solved by themselves. In case of complicated situations, it is recommended to give priority to the brand’s official after-sales service to avoid system damage caused by third-party repairs.
