2. Common symptoms of "gas" in the heating
1.Not hot locally: The upper part of the radiator is hot and the lower part is cool, or the temperature of some groups of radiators is significantly lower than that of other groups.
2.The sound of water flow is obvious: You can hear the obvious sound of running water or bubbles in the heating pipe.
3.Large temperature fluctuations: The heating temperature fluctuates high and low, and the heating effect is unstable.
4.Abnormal pressure gauge: The system pressure value is lower than the normal range (usually should be between 1-2bar)
3. Heating exhaust operation steps
| steps | How to operate | Things to note |
|---|---|---|
| 1. Prepare tools | Flat-blade screwdriver, water container, dry towel | Turn off heating power |
| 2. Position the exhaust valve | Usually on the top side of the radiator | Don't use too much force |
| 3. Exhaust slowly | Turn counterclockwise 1/4 turn | Stop when you hear a "hissing" sound |
| 4. Wait for water to come out | Until the water flow is stable and bubble-free | Close the valve promptly |
| 5. Check the pressure | Supplement system pressure to normal value | Reference pressure gauge standards |
4. Heating maintenance tips
1.Exhaust gas regularly: It is recommended to check once a month during the heating season, especially when the system has just been filled with water.
2.Avoid frequent rehydration: Too much new water will bring in more oxygen and accelerate system corrosion.
3.Install filter: Installing a filter in the return pipe can reduce the accumulation of impurities
4.Professional cleaning: Professional cleaning of the system every 3-5 years
5. Heating problem solving rate statistics
| Question type | Self-resolution rate | Proportion of professionals required |
|---|---|---|
| Simple exhaust | 92% | 8% |
| Valve failure | 35% | 65% |
| clogged pipes | 15% | 85% |
| System design issues | 5% | 95% |
6. When to contact professionals
1. The problem still does not improve after exhausting the gas several times.
2. There is obvious leakage in the radiator or pipe
3. The system pressure cannot be maintained and water replenishment is required frequently.
4. The heating effect of the entire building or unit is poor
From the above analysis, it can be seen that "gas" in the heater is a common problem in winter, and in most cases it can be solved by correct exhaust. It is recommended that users master basic venting skills, but also know when to seek professional help. Keeping your heating system in good condition ensures a warm and comfortable winter experience.
