How to change the water in a gas wall-hung boiler
Gas wall-mounted boilers are important equipment for home heating. Regular water changes can avoid scale accumulation, improve thermal efficiency and extend service life. The following are detailed water changing steps and precautions to help you complete the operation easily.
1. Preparations before changing water
1.Turn off the power and gas valve: Ensure safe operation and avoid accidental startup of equipment.
2.Preparation tools: Bucket, hose, wrench, waterproof gloves, etc.
3.Check water quality: If the water quality is hard, it is recommended to add softener.
| Tools/Materials | Purpose |
|---|---|
| bucket | Receive drained old water |
| hose | Connect the drain valve to the diversion |
| wrench | Unscrew the valve |
| waterproof gloves | Protects against burns and dirt |
2. Detailed explanation of water changing steps
1.drainage stage: - Locate the drain valve at the bottom of the boiler and connect a hose to the bucket. - Slowly open the drain valve to drain out the old water (note that the water temperature may be high). - Observe the color of the drainage water. If it is turbid or contains impurities, rinse it thoroughly.
2.flush system: - Close the drain valve, open the water inlet valve and inject clean water to circulate and flush the pipes. - Repeat draining 2-3 times until the water is clear.
3.Water filling and exhausting: - Close all valves and inject demineralized water from the water inlet to standard pressure (usually 1-1.5Bar). - Open the exhaust valve to exhaust the air until the water flow is stable.
| steps | Operational points |
|---|---|
| Drainage | Open the valve slowly to avoid water splashing |
| Rinse | Multiple cycles ensure cleanliness |
| water injection | The pressure must comply with the instructions |
3. Precautions
-Frequency: It is recommended to change the water 1-2 times a year. In areas with hard water, the cycle needs to be shortened.
-safe: To avoid burns, wear gloves when draining water.
-pressure monitoring: Check the pressure gauge after filling with water. If it is too low or too high, it needs to be adjusted.
4. Frequently Asked Questions
Q: The wall-mounted boiler won’t start after changing the water?
A: Check whether the pressure reaches the standard or whether there is air that has not been exhausted.
Q: What should I do if the drain valve leaks?
A: It may be that the sealing ring is aging and the valve needs to be replaced or tightened.
Through the above steps, you can efficiently complete the water change operation of the gas wall-mounted boiler. Regular maintenance not only improves heating efficiency, but also reduces the risk of failure. If you encounter complex problems during operation, it is recommended to contact professional after-sales service.
