How to deflate the earth heater
With the arrival of winter, earth heaters have become an important equipment for heating many homes. However, it is inevitable that the heater will not heat up during use. One of the most common reasons is that there is air blockage in the radiator. This article will introduce in detail the steps and precautions for deflating the earth heater to help you quickly solve the problem of the heater not being hot.
1. The necessity of deflating the earth heater
During the use of earth heating, air will accumulate in the pipes, causing air blockage. Air blockage will prevent the normal circulation of hot water, thus affecting the heat dissipation effect of the heater. Timely deflation is a key step to ensure the normal operation of the heater.
2. Steps to deflate the earth heater
The following are the detailed steps for deflating the earth heater:
| steps | Operating Instructions |
|---|---|
| 1 | Turn off the power or valves to the heating system and make sure the system is at rest. |
| 2 | Locate the bleeder valve on the radiator, usually located on the top or side of the radiator. |
| 3 | Use a screwdriver or a special bleed key to gently unscrew the bleed valve. A "hissing" sound indicates that the air is being discharged. |
| 4 | Wait until water comes out, indicating that the air has been exhausted, then quickly close the bleed valve. |
| 5 | Turn the heating system back on and check if the radiator is back to normal operation. |
3. Precautions during the deflation process
1.Safety first: To avoid burns when deflating, it is recommended to wear gloves when operating.
2.Avoid over-watering: When deflating, only discharge the air. Do not discharge water for a long time to avoid affecting the system water pressure.
3.Check system pressure: After deflating, check the pressure gauge of the heating system to ensure that the pressure is within the normal range (usually 1-2bar).
4.Regular maintenance: It is recommended to conduct a comprehensive inspection and bleeding operation on the heating system before the heating season every year.
4. Common problems and solutions
| question | Possible reasons | Solution |
|---|---|---|
| The air release valve does not discharge water | The valve is clogged or the system is short of water | Clean valves or replenish system water |
| The heater is still not hot after deflating | Blocked pipes or pump failure | Contact a professional for maintenance |
| Air release valve leaking | Valve seal is not tight | Replace the bleed valve or sealing ring |
5. Recommended tools for deflating earth heaters
The following are tools you may use when deflating:
| Tool name | Purpose |
|---|---|
| deflate key | Special tool to easily unscrew the air release valve |
| screwdriver | An ordinary slotted screwdriver can replace the deflation key |
| Water container | Prevent water from flowing to the ground when deflating |
| gloves | Avoid burns or scratches |
6. Summary
Draining the earth heater is an effective way to solve the problem of the heater not getting hot. It is simple to operate but you need to pay attention to safety. With the steps and precautions in this article, you can easily complete the air bleeding operation and ensure that your heating system is running efficiently. If you encounter a problem that cannot be solved, it is recommended to contact professional maintenance personnel in time.
I hope this article can help you make better use of earth heaters and spend a warm winter!
