地暖进水热回水不热的谜团：工人上门检查令人吃惊
一、地暖进水管热回水管不热原因
管道和地暖内没排气，回水管道阀门没打开
在地热首次运行过程中，因管道里有压力与水阻容易产生气塞，造成供回水不循环、温度不相等。应当进行逐路排气。地暖在钢柱满水后的管道中，会有一定的气体，这有可能导致“地暖进水”。打开排气阀直接排气，直至放出热水为止。
循环动力不足，水压不足
进water pipe和回water pipe会出现一定的water pressure。依靠water pressure使hot water流通。如果water pressure不足，backflow pipe不能流入hot water，就会出现geothermal heating system not working properly.
回water pipe 道坡度不够
如果geothermal heating system ring road pressure is insufficient, it may cause the hot water to flow in one direction and not circulate properly, resulting in geothermal heating system not working properly.
冰凉各个分支中的负荷分布不均匀
就是说 the hot side of the loop has a shorter pipeline or less heat output, causing the hot water to flow directly back out without circulating through the entire system. The solution is to first purge the air from each loop and then measure the water pressure before closing off any valves.
回flow pipe被堵塞
Geothermal heating systems can become clogged over time due to sediment buildup in pipes or other debris that enters the system during installation or maintenance.
二、常见误解的原因有以下几点:
在geothermal heating initial operation phase, supply temperature may be lower than expected and takes longer to rise.
Geothermal radiation provides warmth by emitting heat from below upwards; if there are many objects on top of it (e.g., thick rugs), they can block this process.
三、解决办法:
1-6: Follow steps 1-6 outlined above for troubleshooting common issues with geothermal heating systems.
结论: Geothermal Heating Systems are an efficient way to provide warmth during cold weather but sometimes they malfunction due to various reasons such as low supply temperature, inadequate circulation or improper installation/maintenance practices which need proper attention at home by regular inspection & maintenance activities carried out under supervision of professional technicians when needed!
