How to vent geothermal heat
The geothermal system is an efficient and environmentally friendly heating method, but during use, gas accumulation may occur, affecting the heating effect. This article will introduce in detail the steps, precautions and solutions to common problems of geothermal venting to help you better maintain your geothermal system.
1. The necessity of geothermal venting
In a geothermal system, water circulation is the core of heating. If air accumulates in the system, it will cause poor water flow and affect heating efficiency. Bleeding can remove air from the system, ensuring smooth water circulation and improving heating efficiency.
2. Steps of geothermal venting
| steps | Operating Instructions |
|---|---|
| 1. Turn off the geothermal system | Before deflating, turn off the power to your geothermal system to ensure safety. |
| 2. Find the bleed valve | The purge valve is usually a small screw or knob located above the geothermal manifold. |
| 3. Prepare tools | Prepare a small basin or towel to catch the water that comes out when deflating. |
| 4. Slowly open the air release valve | Use a screwdriver or your hands to gently turn the air release valve. A "hissing" sound indicates that the air is being discharged. |
| 5. Watch the water flow | When the water flow is stable and there are no bubbles, it means that the air has been exhausted, close the bleed valve. |
| 6. Check the system | Restart the geothermal system and check whether heating returns to normal. |
3. Precautions
1.Safety first: Be sure to turn off the power when deflating to avoid the risk of electric shock.
2.avoid burns: The water temperature in the geothermal system is relatively high, so be careful to prevent hot water from splashing out when deflating.
3.Regular inspection: It is recommended to check the geothermal system once a year before the heating season to ensure that there is no air accumulation.
4.Professional help: If the problem is not solved after deflating, it is recommended to contact professional maintenance personnel.
4. Common problems and solutions
| question | Solution |
|---|---|
| Bleed valve cannot be opened | Check the valve for corrosion and replace if necessary. |
| There are still bubbles after deflation | There may be a leak in the system, and the pipe tightness needs to be checked. |
| Heating effect not improved | It may be that the water pump is faulty or the pipe is blocked, and further investigation is required. |
5. Maintenance recommendations for geothermal systems
1.Clean pipes regularly: After a geothermal pipe is used for a period of time, impurities may accumulate, affecting the heating effect. It is recommended that pipes be cleaned every 2-3 years.
2.Check pressure gauge: The pressure of the geothermal system should be maintained between 1.5-2.0 bar. If the pressure is too low or too high, it will affect the operation of the system.
3.Use demineralized water: Hard water can easily cause pipes to scale, so using softened water can extend the life of the pipes.
6. Summary
Geothermal venting is an important step in maintaining your geothermal system. Regular venting can ensure heating efficiency and extend the life of the system. This article details the steps, precautions and solutions to common problems of deflating air, hoping to help you better use and maintain your geothermal system. If you encounter complex problems, it is recommended to contact professionals in time to handle them.
