How to reduce the water pressure of wall-mounted boiler? Analysis of hot topics on the Internet in the past 10 days
Recently, with the increase in heating demand in winter, the issue of wall-hung boiler water pressure has become a hot topic on the Internet. The following is a summary analysis of related topics in the past 10 days (as of November 2023):
| Ranking | Popular questions | peak search volume | Main discussion platform |
|---|---|---|---|
| 1 | Is it dangerous to have too high water pressure in a wall-hung boiler? | An average of 23,000 times per day | Baidu knows, Zhihu |
| 2 | How to reduce water pressure manually | An average of 18,000 times per day | Douyin, Kuaishou |
| 3 | Differences in adjustment methods for different brands | 12,000 times per day | Brand Tieba, JD Q&A |
1. Why do we need to pay attention to water pressure?
The standard water pressure of wall-hung boilers should be maintained between 1.0-1.5Bar. The recent cold wave has caused the following typical situations in many places:
| Problem phenomenon | Proportion | Hazard level |
|---|---|---|
| Pressure gauge exceeds 2.0Bar | 43% | ★★★ |
| Safety valve automatic drainage | 27% | ★★☆ |
| Display error code | 30% | ★☆☆ |
2. 5-step safe pressure reduction method (effective in actual testing on the entire network)
Based on videos with millions of likes from the Douyin life service account "HVAC Lao Guo":
| steps | Operational points | Things to note |
| 1 | Close heating valve | Make sure the boiler is completely cool |
| 2 | Find the location of the drain valve | Usually the red knob on the bottom |
| 3 | Connect drain pipe to floor drain | Prepare a large-capacity water container |
| 4 | Rotate slowly counterclockwise | Drainage no more than 30 seconds at a time |
| 5 | Observe changes in pressure gauge | Stop when it drops to 1.2Bar |
3. Special treatment solutions for different brands
The differences compiled by Zhihu's hot post "Cheats for Lowering Blood Pressure of Various Brands":
| Brand | Drain valve type | reset mode |
|---|---|---|
| power | Quick pressure release button | Need to press and hold for 3 seconds to confirm |
| Bosch | Hidden valve | Requires special tools to open |
| Haier | Electronic drain menu | Need to enter engineering mode |
4. Tips for preventing high voltage in winter
According to Baidu Index data, the number of inquiries about water pressure issues increases by 300% from November to December every year. It is recommended that:
1. Check the pressure gauge value every week
2. Keep the system water replenishment valve in a normally closed state
3. Install automatic pressure relief device (Jingdong’s sales increased by 150% monthly)
4. Floor heating users pay special attention to the status of the expansion water tank.
In case of sustained high voltage or frequent alarms, it is recommended to contact the manufacturer’s after-sales service immediately. Most brands provide free door-to-door inspection services. Do not disassemble core components by yourself.
