Hearing common sense
Geothermal or heating is not hot and the reasons and solutions:
1. Indoor heating pipeline Flow control valve Not open
0Default method: Please open the flow control valve. The valve and the water pipe are in a parallel state, which is open, and the valve and the water pipe are in a cross are closed.
2, water divider filter clog
Treatment method: first close the inlet and return water control valve, close the multiple small valves on and down of the water divider, open the exhaust valve for a few seconds and do not flow water after opening the exhaust valve (long-term water flow proves that the control valve is not closed tightly, please do not continue to operate), use a live-end wrench to open the filter screws, clean the filter inside, and reinstall it. You can also find a professional person to clean it.
3. The water inlet pipe is hot, and the return water pipe is not hot.
Treatment method: Please exhaust the water distributor. There is air in the geothermal tube, which causes the hot water to not enter the circuit to circulate. Generally, water distributors will have exhaust valves, which serve as exhaust. Open the vent valve on the water distributor and degas until hot water is released. For example, if your home is a six-channel water divider, you must first close the return water control valve, and then turn off the five channels in turn (you can only operate one way, and only one way is open each time), open the return water exhaust valve, and release the water all the way until only water is discharged but not air is discharged. Then, open the return water control valve normally, listen to whether there is any sound of water flowing, observe for a while, touch whether the return pipe is hot.
4. Uneven circuit
. Treatment method: Use the small valve on the water distributor to adjust the circulation of each circuit so that it can circulate evenly and achieve the ideal heating effect. If the difference is not too great, please do not move.
5. Floor heating pipes have not been cleaned all year round
Treatment method: If the floor heating effect was normal in the past, it was only this year that the floor heating was not hot. (The above 4 reasons are excluded) This may be because after living for a long time, the floor heating water pipes will produce impurities and scales after use. After several years of long-term attachment to the inner wall of the water pipe. If they are not cleaned and maintained in time, the inner diameter of the floor heating pipes will gradually narrow, and the water flow will become smaller and smaller, which will directly affect the heating effect. In this way, you need to find a floor heating cleaning company to clean the floor heating water pipes.
6. All water is not released after the heating period ends.
Treatment method: After the heating period ends every year, all water in the floor heating pipes should be discharged. Otherwise, the long-term deposition of water in the water pipe will cause the water flow to decrease, poor flow of water, and the efficiency of heat conduction of will be reduced.
If you find that a water discharge valve and circulation pump are installed in your neighbor's home, this is also the reason why your home is not hot, you can report the situation to the heating company in time.
Many friends have also purchased various small heating, but do you know that heating also needs to be used with caution.
